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.
The varieties of these walls are many. Gravity, anchored, piling, and cantilever walls are major examples. They are constructed to offer support to a wedge of soil. Gravity causes retained soil to tend to shift downslope. Therefore, the way the structure is designed and installed must counteract this tendency. Lateral earth pressure starts to occur because of the gravitational pull. Generation of pressure differs according to cohesive strength and the angle of friction 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.
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.
Soft grounds and tight spaces do well with sheet pile retaining walls. The materials used to make these walls are many and diverse and they include steel bars, vinyl, and wood planks. One third of the material protrudes above the ground wile the other two third is driven underground. Theses measurements can be changed as dictated by 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.
Evolution of construction styles has been very fast. There are many diverse methods of reinforcing walls after being constructed. Retention methods are also many and the common ones include soil-strengthening, soil nailing, cellular confinement, and gabion meshes.
