Did you ever wonder what occurs to the rocks which are being broken down by the river current? Or have you ever thought about times when landslides happen and break all the transportation links? The rocks carried down and eroded by the rivers can be reused to build blocks so that the effect of the landslides can be reduced.
So what is a retaining wall?
A retaining wall is an arrangement designed and built to resist the sideways pressure of earth when there is an anticipated alteration in ground raise that beats the angle of repose of the loam. These are constructed from a footing and upsurge above the grade on one and only side to retain an advanced level grade on the reverse side. The walls must resist the lateral pressures generated by loose soils or water pressures.
Nearly all of the retaining walls support a chunk of soil. The wedge is well-defined as the soil which ranges beyond the plane of the soil present at the side of the wall, and which can be calculated form the soil friction angle. As the hold-up of the wall increases, the size of the wedge is reduced. Therefore, this decrease in size lowers the pressure onto the retaining wall for more benefits. So we can say that Retaining Walls – Perfect for Earth Retention.
The most important aspect in proper designing and installation of such reinforcement retaining walls so that recognition and counteract of the tendency of the retained material which is to move down slope due to the power of gravity. This creates the lateral pressure of the earth or soil behind the wall which depends solely on the angle of internal friction and also the cohesive strength of the retaining material, as well as on the direction and magnitude of drive which the retaining structure experiences. This is the main idea behind the Retaining Walls – Perfect for Earth Retention.
Types of retaining walls
Gravity walls entirely depend on their total mass to resist the pressure from behind of the wall and give a setback to improve the stability by being inclined back toward the retained soil. The dry-stacked gravity walls are flexible in nature and generally do not require a rigid footing in snow-capped areas.
The cantilevered retaining walls are made up of an internal stem of steel or sometimes casted concrete or masonry works shaped like the English letter T. These walls cantilever features a large structural footing thereby converting the horizontal pressures from the back of the wall to the vertical pressures on the ground below the wall.
The third type of retaining walls being the sheet pile retaining walls are generally used in soft soils and tight spaces. Such walls are usually made out of steel, wooden or vinyl planks which are driven into the ground.
Bored pile retaining walls are usually built by assembling a complete sequence of board piles kept by digging away the excess soil from the surface.
An anchored retaining wall is constructed using any of the mentioned styles but this also includes some additional strength using cables or other measures which are anchored in the rock or soil behind it.
