Retailing walls are walls designed to for restraining soil to slopes that are not natural. They help to retain soils between two places of uneven elevations. They are made in different places. They are made in places to allow for severe engineering and shaping to serve other purposes like hillside farming. A retaining wall may also be made in regions with undesirable slopes.
These walls come in many types. Common examples are gravity, cantilever, anchored, and piling walls. Their purpose is supporting a wedge of soil. The retained soil tends to shift downslope because of gravitational pull. As such, the design and construction must be done in a way as to counteract this tendency. Gravitational pull results in lateral earth pressure in the supported material. How much pressure is generated varies with the angle of friction and cohesive strength of retained material.
The ability of gravity walls depends on their mass to resist pressure behind. They get made of heavy material including concrete and stone. Batter setback may be incorporated to improve their stability so that they lean back toward the material that is being held back. The dry-stacked variety of gravity walls are made flexible and in areas prone to frosting, the footing is not made rigid.
Most retaining walls constructed during the early years of the 20th century were of the gravity variety. Their construction was done using big masses of concrete and stone. Those that are being constructed in modern times are made of composite materials. Major construction materials include crib walls, soil-nailed walls, and gabions. Construction of gabions is done using stacked steel wire baskets which are filled with rocks.
The making of cantilevered retaining walls involves the use of internal stems of steel-reinforced, cast-in-place concrete, and mortared masonry. In some circumstances, buttressing is done to the front side. More strength for supporting heavier loads is achieved through the addition of counterfort. Fronts may also be buttressed. Buttresses resemble wing walls and their installation is done perpendicularly to main walls. It takes less construction material to make cantilevered walls in comparison to gravity walls.
Sheet pile retaining walls are placed in tight spaces and soft soils. They are made from a wide variety of materials including wood planks, vinyl, or steel driven into the soil. At least a third of the material is driven into the ground while two thirds remain above the ground. However, depending on the environment, these measurements may be altered.
Construction of bored pile walls involves assembling sequences of bored piles. Excess soil on the site of construction is excavated first. Many techniques are employed in the construction process including reinforcing beams, earth anchors, shotcrete reinforcement layer, and soil enhancement operations. Bored pile walls and sheet piling walls can be constructed in the same location. Bored pile walls are preferred if noise and vibration levels are not supposed to be very high.
Styles of construction have evolved a lot. In the same way, methods of reinforcing the walls are many and diverse. Some common methods of retaining include cellular confinement, soil nailing, soil-strengthening, and gabion meshes.
