If there is no retaining wall support, the soil at a higher elevation would tend to move down till it acquires its natural, stable configuration. Consequently, the soil that is now retained at a steeper slope than it can sustain by virtue of its shear strength exerts a force on the retaining wall.

It is most popular types of retaining wall. Gravity wall assures its stability by its own weight. These walls are majorly designed to eliminate the overturning effect of the lateral earth pressure and do not induce tensile stresses within the section. Gravity retaining walls are suitable for the low height and are not economical for large heights. It can be made from stone, bricks, mass concrete, and precast concrete blocks.

Its section is of trapezoidal shape with a base width between 0. In the case of a concrete gravity retaining wall, a top width of 0. Reinforced concrete cantilever types of retaining wall are recommended for heights up to 7 m. This type of walls has vertical stem monolithic with the base.

A slender section can be used in this retaining wall the tensile stresses within the stem and the base is resisted by steel reinforcement.

In case the slope of the wall is exposed a small backward batter of about 1 in 50 is provided in order to compensate for any forward tilting of the wall as shown in Figure. Counterfort retaining walls are used for height more than 6m.

Its stem provided act as slab spanning between the counterfort supports. A buttress wall is a retaining wall details 2021 of counterfort walls. These types of retaining wall retaining wall details 2021 built on the face of the wall and not within the backfill, retaining wall details 2021. Buttress walls are not too popular because of their buttressed shape exposed outside which consumes space and spoils the appearance.

The crib wall is shown in the figure. Crib walls consist of a series of boxes made from timber, precast concrete or steel members, which are filled with granular soils.

It acts as a gravity wall with the advantage of a quick erection. Crib walls can withstand large displacement of soil due to its flexible nature. It is usually fitted so that its face has a batter of 1 in 6. The width of the wall varies from 0. Note that the crib wall should not be subjected to surcharge loadings.

These types of retaining wall constructed from rectangular metal cages or baskets. A gabion wall is made from a square grid of steel fabric, generally, 5 mm in diameter and spaced 75 mm apart. The gabion baskets are usually 2 m long and 1 m in cross-section. Each basket is provided with center diaphragm divides it into two equal 1 m 1 m sections and adds stability. At the time of making stone-filled baskets are secured together with steel wire of 2, retaining wall details 2021.

The base width of the gabion wall is about 0. Retaining wall details 2021 typical wall is shown in figure. A good looking face can be provided by slightly stepping back each succeeding layer. Sheet pile retaining walls are constructed from a series of interlocking piles individually driven into the Retaining Wall Quotes Near Me Uniform foundation soil. Nowadays, modern sheet piles are constructed from steel, retaining wall details 2021, timber or precast concrete sections are also used.

Sometimes, a Cantilever retaining wall details 2021 pile walls are held in the ground by the active and passive pressures that act on its lower.

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. Diaphragm walls can be of a reinforced concrete wall or sheet pile wall.

It includes a vertical concrete reinforced concrete slab fixed in position. Wall is held in position by the passive and active pressures acting on its lower portion. In this types of retaining wall the use of reinforcement to strengthen the soil has been known for centuries. In past straws are used to strengthen unburnt bricks and fascine mattresses have been used to strengthen soft soil deposits prior to road construction. The main phenomenon working in reinforced earth wall is that a mass of soil can be given tensile strength in a specific direction if the lengths of a material capable of carrying tension are embedded within it in the required direction.

Reinforced earth has been used in many geotechnical applications. Here, retaining wall details 2021, we are only concerned with retaining structures. A reinforced earth wall is a gravity structure.

Its stem provided act as slab spanning between the counterfort supports. Steel is a good choice for sheet piling, as it can also be used to create thin walls. A new section was added on the uses of retaining walls. Layered walls will be built one section at a time, with reinforcement as needed past a specific height.
