Types of Retaining Wall. Gravity Retaining Wall ; 2. Timber; 9. (8.3) which are then analyzed for stability and structural requirements and revised as required. Cantilever retaining wall composed of stem and base slab. Where foundation soils are poor, earth tieback retaining walls are another choice. However, the discharge of the tremie pipe always remains embedded in the fresh concrete. Types of Retaining Wall. The construction sequence usually begins with the excavation of discontinuous primary panels. A very basic kind of wall usually used when space is an issue, a sheet pile retaining wall is a thin wall of steel, wood, or vinyl that is driven directly into the soil. 8 Retaining Wall Designs (Diagrams) 1. Lift the sides, the ends, and the diaphragms of each unit into vertical position. Concrete retaining walls are used in various locations to keep soil and other materials firmly in place. Type # 1. Similarly, secondary panels are constructed between the primary panels, and the process continues to create a continuous wall. d. Assemble the empty gabion baskets individually and place them on the approved surface. Each unit is securely connected to each adjacent cage during construction. All Rights Reserved. Crib walls have been made of various materials, including wood, concrete, and even plastic. This attribute enables the gabion structure to be built with minimum foundation preparation. You will receive a link and will create a new password via email. Cantilever Wall; 4. Gravity retaining walls are designed to resist earth pressure by their weight. Mechanically stabilized earth retaining wall is supported by selected fills (granular) and held together by reinforcements, which can be either metallic strips or plastic meshes. Reinforced cement con­crete (RCC) sheet piles may be sometimes used in fine sand or soft clays. This type of wall is found to be economical upto a height of 6 to 8 m. More than one set of anchors or tiebacks can be used. Gabion Retaining Walls. Gabions form flexible structures that can withstand the movement of the ground without inordinate structure deformations. Retaining walls are the structural components, which are designed with the purpose to retain the soil mass of two different ground levels. There are different types of concrete blocks – interlocking, hollow, solid and half hollow manufactured in high or low density. The three main types of retaining walls are concrete, and masonry or stone. What is a retaining wall? Gabion Retaining Walls ; 4. Buttressed Retaining Walls 6. It is employed in both temporary and permanent works. For ease of handling and shipping, the gabions are bundled and folded flat. This retaining wall is massive. Considerably high retaining wall can be constructed using this type of retaining wall structure system. When designing this type of retaining wall, sliding, bearing and overturning forces should be considered and tested. 16.4. Concrete is then poured in one continuous operation, through one or several tremie pipes that extend to the bottom of the trench. Become VIP Member, Do you need to remove the ads? The base of the wall is extended into the backfill on the heel side and is known as heel slab, as shown in Fig. The main elements to consider when building a retaining wall are materials and quality of installation. This increases the width of the wall with depth, similar to the increase in lateral earth pressure with depth. Types of Retaining Walls; 1. Each unit is filled with free draining material. The thickness of sheet piles is very small compared with the depth and length of a wall. Sheet piles are made of timber, steel, or sometimes reinforced concrete. Cantilever retaining wall is either constructed on site or prefabricated offsite i.e. There are various types of retaining wall structures which are used for numerous goals. Hence, the design of cantilever sheet piles involves determination of the depth of embedment of the sheet pile to ensure its lateral stability. Crib walls are one of the oldest gravity wall systems, composed of a series of stacked members, creating hollow cells filled with soil or rock. What are the important points of FIDIC Contract we should keep in mind during tendering? The advantages of steel sheet piles are that they are water tight and can be removed and reused after the construction of the structures is completed. This is most obvious in dams, or simple dykes. Counterfort Wall; 5. 16.5. Retaining Wall Types, Materials, Economy, and Applications. Gabion aprons are commonly used to protect the toe of a gabion retaining wall structure from scour that could cause undermining in channel works applications. Vegetation can be re-established around the gabions and can soften the visible edges, allowing them to blend into the surrounding landscape. Concrete Blocks; 2. Mechanically Stabilized Earth (MSE) Retaining wall. Anchored Wall; 2. It is employed for construction of erosion control structures. Semi-Gravity Retaining Walls A specialized form of gravity walls is a semi-gravity retaining wall. Gravity Wall 1; 6. Semi-Gravity Retaining Walls 3. Counter-fort wall height ranges from 8-12m. Which country provides highest salary to the civil engineer? In the case of sheet piles, lateral support is mainly derived from the pas­sive resistance of the soil below the dredge level. The depth of foundation is usually small, and passive resistance of the soil is usually neglected in the design. The anchors are provided to reduce excessive deflections. Crib Retaining Wall; 3. Piled walls offer high stiffness retaining elements which are able to hold lateral pressure in large excavation depths with almost no disturbance to surrounding structures or properties. The vertical wall (known as stem), the heel slab, and the toe slab act as cantilevers fixed at their junction and spanning to the other end. There is a wide choice of stone types, enabling you to select a material that best suits your architecture and outdoor space. 16.11. It requires smaller quantity of concrete compare with gravity wall but its design and construction shall be executed carefully. When the height of a cantilever retaining wall is more than about 7 m, it is economical to provide a vertical bracing system, known as counterforts, on the backfill side above the heel slab. The lateral pressure could be also due to earth filling, liquid pressure, sand, and other granular materials behind the retaining wall structure. Crib walls are constructed of interlocking prefabricated units of reinforced or unrein-forced concrete or timber elements. Sliding, overturning, and bearing forces shall be taken into consideration while this type of retaining wall structure is designed. Cantilever Retaining Walls 4. The stem is subjected to lateral earth pressure, causing bending away from the backfill. The bars or strips, sometimes called “dead- men” are made of wood, metal, or synthetic materials, such as geotextiles. Lost your password? Retaining walls are the structures that are built to retain the soil or retain raw materials or maintain level differences between the adjacent plots. Hybrid Systems Become VIP Member. The use of counterforts reduces the bending moment due to earth pressure and hence the size and reinforcement of the stem and the heel slab. Sheet pile walls are built using steel sheets into a slope or excavations up to a required depth, but it cannot withstand very high pressure, Sheet pile retaining wall economical till height of 6m. 1. Counterfort Retaining Walls 5. A cantilevered wall holds back a significant amount of soil, so it must be well engineered. In the case of anchored sheet piles, additional lateral support is provided by means of anchor rods fixed to the sheet pile near the top and anchored suitably, as shown in Fig. A cantilever retaining wall is one that consists of a wall which is connected to foundation. Crib retaining wall, gabions, and bin retaining wall are also type of gravity retaining walls. Individual steel sheets are joined by ball-and-socket joints to obtain the required length of sheet piles. RCC piles may get damaged or broken under driving stresses in stiff soils. Hence, the depth of foundation (embedment) is large compared with that in a retaining wall. Gabions are used to retain soil up to small heights of 3-4 m. Gabions are particularly used, where the retaining wall needs to allow high amounts of water to pass through it, such as hydraulic structures in river training works and in protection works for roads and land reclamation. The following is the procedure for installation of gabion walls: a. Mechanically Stabilized Earth (MSE) Retaining wall, Types of Drawings used in Building Construction, Types of Brick Mortar Joints in Masonry Construction, Void Forms in Foundation Construction: Their Types and Applications, Important Know-How on Progressive Collapse of Building Structures. It is commonly required in the construction of hill roads, masonry dams, abutments and wings walls of bridges and so on. Cradle Retaining Walls: They are a type of gravity wall, constructed from a particular person interlocking packing containers, which might be made from wooden or precast concrete. Gabion baskets (steel baskets filled with stones) are an excellent example of this, as they do not require concrete … For short landscaping walls, they are often made from mortarless stone or segmental concrete units (masonry units). The back of the wall on the heel side is also given a slope. The backfill over the heel slab provides significant additional lateral stability to the wall. An earth retaining structure can be considered to have the following types: Gravity Walls Reinforced Gravity Walls; Concrete Cantilever retaining wall; Counter-fort / Buttressed retaining wall; Precast concrete Ret wall; Pre-stressed retaining wall; Brick Brick Masonry retaining wall; Stone; Reinforced Soil Walls Reinforced Soil However, the soil below the dredge level may be either a cohesionless soil or a cohesive soil, depending on the soil profile at the site of construction. Cribs are made of interlocking headers and stretchers that are stacked like the walls of a log cabin. 17: Mechanically stabilized earth retaining wall. Often these have a vertically corrugated structure to provide additional reinforcement. It is constructed from reinforced concrete, precast concrete, or prestress concrete. This video is about Retaining Wall Types and Retaining Wall Design. Mechanically Stabilized Earth (MSE) Retaining wall ; 9. Gravity walls require heavy foundation due to the large size of the wall. Generally, a gabion apron and a gabion block are placed directly on the ground utilizing a geotextile filter fabric between the gabions and soil interface to prevent leaching of soils underneath the gabions. Gabion structures behave as perforated barriers, allowing water to gradually pass through them. Based on the behavior, retaining walls can be broadly classified into the following types: Gravity Walls: Soil Engineering, Retaining Structures, Retaining Walls, Terms of Service Privacy Policy Contact Us, Copyright infringement takedown notification template, Lateral Earth Pressure: Types and Derivation | Soil, Shear Failure of Soil: 3 Modes | Soil Engineering, Soil Formation: How is Soil Formed [with Factors and Processes for Class 7, 8 ,9, 10], Exam Questions with Answers on Soil Mechanics [Geotechnical Engineering], List of Objective Questions on Soil and Water Engineering (With Answers), Soil Compaction: Meaning, Compaction, Methods and Effect | Soil Engineering. What is a retaining wall? Anchored Retaining Wall ; 7. Gravity walls derive their lateral stability by their mass. The lateral stability of anchored sheet piles is derived both from the embedment into the soil below the dredge level as well as by the support provided by the anchor or tie rod. Sign Up to The Constructor to ask questions, answer questions, write articles, and connect with other people. Though there is one common use for a retaining wall, there are several different types of retaining walls. 11: Counter-fort or buttress retaining wall, Fig. Retaining wall is a structure that are designed and constructed to withstand lateral pressure of soil or hold back soil materials. It is suited to support planter areas, but it is not recommended  for support of slopes or structures. 10: Different configuration for cantilever retaining wall, Fig. Retaining wall is a structure that are designed and constructed to withstand lateral pressure of soil or hold back soil materials. These walls are counterbalanced not only by a large base but also by a series of horizontal bars or strips extending out from the vertical surface into the backfill. Diaphragm walls are commonly used in congested areas for retention systems and permanent foundation walls. precast. These have some tension reinforcing steel included so as to minimize the thickness of the wall without requiring extensive reinforcement. why risk of efflorescence formation in cement based materials is high in coastal areas? The slurry exerts hydraulic pressure against the trench walls and acts as shoring to prevent collapse. The stem and the heel slab act as continuous slabs spanning horizontally along the length of the wall between the counterforts. The lateral earth pressure is principally resisted by the mass of the wall, as in the case of a gravity retaining wall. In this article, we will review the different types of retaining walls and what they are used for in the world. Buttressed Retaining Walls 6. Retaining wall according to S ystem Rigidity Can be classif ied as follow: 1-Rigid wall 2-Flexibale wall, Sheet pile walls are more flexible than the other types Wood; 6. Counter fort spacing is equal or slightly larger than half of the counter-fort height. The toe slab acts as a continuous slab spanning along the length of the wall between the buttresses. Figure 16.6 shows a buttressed retaining wall. Achored Wall (Screw Design) B. Fig. #cd 💐 The heel slab and the toe slab are subjected to resultant upward soil pressure from the bottom and bend upward. Types of Retaining Wall. However, the heel slab acts as a cantilever slab as in a cantilever retaining wall. These types of retaining walls normally include a facing element and a reinforcement element embedded in the backfill behind the facing. 16.13. These are the reinforced concrete walls in which lateral earth pressure is resisted by structural action of its members. This type of retaining wall is employed when the space is limited or thin retaining wall is required. The facing element can be concrete, segmental block or panel, or steel wire mesh. The purpose of all retaining walls is to hold soil behind them. Hence, the back­fill for all sheet piles is a cohesionless soil. Their strength and effectiveness may increase with time, as silt and vegetation fill the voids and reinforce the structure. f. Place a well-graded stone into the gabion units in 300-mm lifts. The Cantilevered wall rests on … Stone veneer; 3. Timber sheet piles were used in the past but their reuse is limited for temporary structures up to shallow depth. Multi-tiered gabion walls can be installed using galvanized gabions as well as geogrids and geotextiles, creating a “MSE wall” (mechanically stabilized earth). In the case of cantilever sheet pile walls, if the deflection at the top point of the sheet pile wall is very large, then settlement of soil takes place at the top just behind the sheet pile wall. Sheet Piles 7. Counterfort Retaining Walls 5. The following are the various types of retaining walls: 1. It is important to use a filter fabric with the gabion to keep the adjacent soil from flowing into or through the cages along with the water. It is among the most economical and most commonly constructed retaining walls. 10 Retaining Wall Materials. 3: Pressure acting on gravity retaining wall, Fig. e. Connect all adjoining empty gabion units along the perimeter of their contact surfaces to obtain a monolithic structure. The retaining wall prevents the failure of the soil mass from sliding, overturning, shearing, and toppling. When you begin the initial planning, there are several considerations that will affect the material and type of wall you build. What is the difference between Airport, Aerodrome and Airfield? Gravity retaining wall depends on its self weight only to resist lateral earth pressure. Gravity Walls: Gravity walls derive their lateral stability by their mass. A. The following are the various types of retaining walls: 1. A gabion retaining wall is also a type of gravity retaining wall, the best way to think of a gabion retaining wall is a large scale lego set. Types of Retaining Walls. ; Overturning of retaining wall, which is a vertical movement due to excessive pressure on the top portion of the retaining wall. Diaphragm walls have also been used as groundwater barriers below dams. It includes a vertical concrete reinforced concrete slab fixed in position. The wall consists of a thin stem and a base slab cast monolithically. Retaining walls are among the essential structures of a residential landscape used not only to enhance the area’s overall appearance but also to retain soil and rocks from shoving off uneven grounds. Gabion bridges have been built in the African Congo as a low-cost alternative to concrete culverts. Crib retaining walls are a form of gravity wall. The design of anchored sheet piles involves determination of the depth of embedment as well as the force (tension) in the anchor rod. 8) Anchored Earth Walls: These types of retaining walls are fixed at the base and are supported by a row or two rows of ties or struts placed near its top. It is also used to stabilize steep slopes. This is a valuable char­acteristic as hydrostatic pressure never builds up behind or under the structure to cause failure. Brick; 5. Login to The Constructor to ask questions, answer people’s questions, write articles & connect with other people. Counter-fort / Buttressed Retaining Wall ; 6. The gabions are steel wire cages filled with quarry run or river run stones available at the site of erection. They normally created of solid in situ concrete, masonry block walls, or significant timber. Retaining walls are complete walls that perform as a part of landscaping. When the triangular beams are placed on the front side of the retaining wall, instead of on the backfill side under certain situations, the retaining wall is known as buttressed retaining wall, and the triangular beams are known as buttresses, instead of counterforts. A properly installed wall will withstand the elements and last for decades. Gabion walls are constructed by stacking and tying wire cages filled with trap rock or native stone on top of one another. Crib wall systems can be aesthetically pleasing because they can accommodate complex curvature and be planted with climbing vines, giving them a much “softer” appearance than more conventional support systems. Country They are constructed of interlocking individual boxes made from timber or pre-cast concrete. Others are elements of building, road, or bridge infrastructure. The structural action of the stem is the same as in a counterfort retaining wall. For local roads, they are a preferred low-cost retaining structure. Sorry, you do not have permission to ask a question, You must login to ask question. A good retaining wall designer chooses the right type of wall … The anchorage is provided by means of an anchor or tieback at or near the head of the wall. The counterforts are triangular beams of variable depth and uniform width, connecting the heel slab and the stem, provided at a regular spacing along the length of the wall, as shown in Fig. A type of retaining wall which depends on its own weight alone to stand up is called a gravity retaining wall. Then, the boxes are filled with crushed stone or other coarse granular materials to create a free draining structure. 13: Different configuration for anchored retaining wall, Fig. The following are the different types of anchorages used for anchored sheet piles: The different types of anchorages provided to sheet pile walls are shown in Fig. The slurry, which is displaced by the concrete, is saved and reused for subsequent panel excavations. Gabion structures are regarded as permanent. 8.3.2 Tentative Dimensions of Common Types of Retaining Walls Retaining wall design proceeds with the selection of tentative dimensions, see Fig. Gabion; 8. 2: Materials used for gravity retaining wall construction, Fig. Standard sections of steel sheet piles as suggested by US Steel (1984) are shown in Table 16.3. Stop-end pipes are placed vertically in each end of the primary panels to form joints for adjacent secondary panels. 9) Diaphragm Walls: Diaphragm walls can be of a reinforced concrete wall or sheet pile wall. Sheet piles having water on the front side used in dock and harbor structures to facilitate berthing of vessels (ships) are known as bulk heads. Since this is a trial process, several solutions of the problem may be obtained, all of which are 9: Different pressure on cantilever retaining wall, Fig. Basic types of crib retaining walls include reinforced precast, and timber retaining walls. Sheet Piles 7. When the concrete sets, the end pipes are withdrawn. The level up to which the soil is dredged out on the front side of the sheet pile is known as dredge level. Dry-stacked gravity walls are somewhat flexible and do not require a rigid footing. Hence, the weight of a sheet pile is very small and is usually ignored in the design. Top 5 Residential Retaining Wall Types and Their Uses. Piles are forced into a depth that is sufficient to counter the force which tries to push over the wall. The soil on the front side is then dredged (removed) out. Reinforcement is therefore provided on the tension side, that is, vertically on the backside of the stem and horizontally at the bottom of the heel slab and the toe slab. Buttresses are subjected to compression due to lateral earth pressure of the backfill on the stem and that due to upward soil pressure on the toe slab. A gravity retaining wall is thick at the bottom and narrow at the top while a counterfort wall is situated above and below the ground level. Gabion retaining wall walls are multi-celled, rectangular wire mesh boxes, which are filled with rocks or other suitable materials. The market offers a wide variety of designs, types, shapes, colors and textures and a cinder block retaining wall provides both aesthetic value and structural integrity. 16.2. The depth of embedment depends on the depth of soil to be retained above the dredge level and the type and properties of the backfill and the underlying soil below the dredge level. Piled Retaining Wall ; 8. 16.3. Retaining Walls – Types, Design, Stability. Each crib is composed of longitudinal and transverse members. Sliding of retaining wall, which a linear horizontal movement of the entire structure. Cantilever Retaining Walls 4. A gabion apron will require minimal excavation and grade work. Heavy construction equipment is required to lay the courses, possibly impacting sensitive areas. Cantilevered “L” Wall; 3. Retaining wall clad in Roda Linear Walling by Lexis Design This is arguably the most attractive option, blending seamlessly with the landscape. In view of the environmentally friendly nature of the gabion construction as compared with concrete, gabions are becoming more popular in engi­neering works in river embankments which demand a natural-looking environment with growth of vegetation and potential for ecological lives. Others can help control erosion from hard rains or create a terraced yard to reduce maintenance. They can be installed in close proximity to existing structures, with minimal loss of support to existing foundations. It is a cantilever retaining wall but strengthened with counter forts monolithic with the back of the wall slab and base slab. Cantilever Retaining Wall ; 5. Cantilever retaining wall is the most common type used as retaining walls. The fill layer should never be more than 300-mm higher than any adjoining cell. 16.12. The portion of the base slab beneath backfill material is termed as heel, and the other part is called toe. Limestone; 11. There are several different types of concrete retaining walls designed for various applications. Poured Concrete; 4. Natural stone; 10. Boulders; 7. Cantilever Retaining Wall Cantilever retaining walls are made of reinforced cement concrete. Counter-fort / Buttressed Retaining Wall, 8. Gravity Walls 2. When sheet piles are used for construction of structures in coastal regions on the sea shore, water will be there up to some depth on both sides of the sheet pile. Soil bearing failure of retaining wall, which is due to the inadequate load-bearing capacity of ground soil beneath the footing or foundation of the retaining wall. What is the percentage of carbon in wrought Iron? Anchored retaining wall is suitable for loose soil over rocks. The retaining height and other factors usually decide the type of retaining wall. They are economical and suitable for only small heights. For all important structures and for depth > 3 m, steel sheet piles are more commonly used. Cantilever retaining wall is economical up to height of 10m. Then, filled with crushed stone or other coarse granular material to sort the free-drain structure. Please enter your email address. A gravity retaining wall provided with a small amount of reinforcement for reducing the mass of the concrete is known as semi-gravity retaining wall, as shown in Fig. The tremie pipes are extracted as the concrete rises in the trench.
