Geogrid reinforced earth retaining wall technology

The so-called geogrid-reinforced retaining wall technology is to perforate a high-density polypropylene or polyethylene board and then heat it to stretch it in one or two directions. The purpose of this is to improve the directional arrangement of molecular bonds and obtain a reinforced material with high strength and low elongation.

Under the influence of its high tensile strength and continuous plate-shaped opening structure, the wall can be better fixed, and the inside of the soil can be evenly reinforced, thereby effectively preventing the sinking of the filler. In addition, there is a certain frictional resistance between the geogrid and the soil, and its wall can play a blocking role. If its design calculation is reasonable, it can ensure the safety of the structure and can withstand relatively large dynamic and static loads.

Geogrid reinforcement technology widens roadbed

In this process, the combined stress of the filler layer can be diffused and then distributed in a wide range, thereby increasing the shear strength of the roadbed and further improving the stability of the roadbed.
Among all reinforced materials, geogrid is an important material, which is widely used in modern highway construction. In the construction of a highway embankment, the most important thing is the vertical bearing capacity and the axial thrust to both sides, which can effectively reduce the vertical bearing capacity of the foundation.

In its construction, the geogrid-reinforced retaining wall can effectively reduce the horizontal load of the embankment and effectively increase the actual bearing capacity of the road subgrade. If this technical method is not used in the construction of highway embankment, the subgrade filling will be relatively loose and will not fully limit the vertical load from the surface soil of the foundation, but if the vertical load of the foundation can be well limited, it can be significantly improved The vertical load of the foundation. The unevenness of the highway embankment base will limit the surface soil of the foundation and increase the vertical load of the highway embankment. From a large amount of actual construction, this technology can play a good coordination role in the settlement capacity of the foundation and reduce the occurrence of soil arching effects.
