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.
There are many types of these walls. Some of the examples are gravity, piling, cantilever, and anchored walls. They are meant to support a wedge of soil. The design and construction is done in a way as to counteract the tendency of retained material to shift downslope as a result of gravity. Gravity creates lateral earth pressure on the back of the wall. The pressure depends on the angle of friction and cohesive strength of the material retained.
Gravity walls rely on their mass for resistance of pressure exerted on them by pressure behind. Construction is done using stones and concrete to make them heavy. Stability is improved by incorporating batter setback. Sometimes they are made to lean toward the load. Dry-stacked variety is constructed to be flexible and when constructed in regions where frosting occurs, their footings are made rigid.
Gravity walls dominated in most sites during the first half of the twentieth century. Big stones and concrete were used in their construction. During the second half of the century, gravity walls started to be made using composite materials. Gabions, crib walls, and soil-nailed walls were the major construction materials in use. Rocks are used to fill stacked steel wire baskets to construct gabions.
Cantilevered retaining walls are constructed from an interior stem made from cast-in-place concrete, mortared masonry, or steel-reinforced. Cantilevered walls sometimes get buttressed at the front side. The back may also comprise of a counterfort to enhance the strength of the walls necessary for resisting lofty loads. Buttresses are made in the form of wing walls placed perpendicularly to the main wall trend. These walls need less material to construct compared to gravity walls.
Tight spaces and soils that are soft are suitable with sheet pile retaining walls. This variety is made from various materials including vinyl, wood planks, and steel, which are driven underground. About two thirds of the material stands above the ground while a third is driven underground. The measurement of material driven underground and the one remaining above may be varied depending on the situation.
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.
