Different Types of Retaining Wall

Retaining wall indicates one type of structure which are constructed and designed to hold back the side to side force of the soil materials. Because of the liquid pressure, earth filling and other sandy materials, the side to side pressure is felt on the structure of the retaining wall. Different types of retaining wall blocks are used based on different types of goals.

Different types of retaining wall:

Here we will discuss about different types of retaining wall which are so popular.

1.     Gravity

This type of wall prevents the lateral pressure depending on the self-weight. Gravity retaining wall can take the significant load to prevent the pressure of the soil. We must consider the overturning, bearing and sliding forces for designing this retaining wall.

This type of block can be made from different kinds of substances, for example, stone, masonry units and concrete. In the height of 3 meters, this can be an economical solution. Bin, gabions, and crib are also different types of retaining wall, which is very popular for construction work.

2.     One of the Best Types of Retaining Wall :Crib

These walls are constructed with the interlocking of boxes which are made from pre-cast concrete or timber. To make a free structure of drainage, using the granular materials and crushed stone, these boxes are pervaded. In the basic kinds of the crib, we may find timber and concrete for the reinforcement of the pressure.

This can work best for the support of the planter areas, but it should be avoided to use as the support for the sloppy structures.

3.     Gabion

These retaining walls have rectangular mesh boxes with multi-cells which are filled with the rock-like materials. These are very useful for controlling erosion. To fix the steep slopes, these kinds of blocks are also used.

4.     Cantilever

With the composition of the base slab and stem Cantilever retaining wall are built. It is the most used type of retaining wall. Generally, it can be prefabricated or constructed on the site. The part of the base slab is called the toe, and the material which is beneath the backfill is known as base slab.

Up to a height of ten meters, it can prove as very economical. Thought it requires less amount of concrete if we compare it with the gravity, but the construction and the design must be performed carefully. Like the gravity wall, bearing pressure, overturning and sliding must be considered.

5.     Counter-fort

This is another type of cantilever wall which reinforce the counter forts with the base slab and the wall back. From the half of the height of counter-fort, the spacing can be slightly larger or equal. The height of the wall can range from 8 meters to 12 meters.

6.     Anchored

In the limited space this kind of wall can work as a great saving. For the loose soil on the rocks, it can be very suitable. Using this type of retaining wall, great structures can be built. With concrete, the ends are surpassed, which provides a strong grip to hold the pressure.

These are the most used retaining wall to which help to support the soil steadily for roads beside the hills and other infrastructures. Before choosing a type, we should consider the holding power, sliding and the strength based on different situations. If you like this you may also check how to build a concrete retaining wall.
