Description

Technical Field

[0001] The invention relates to the technical field of highway retaining walls, and in particular to an integrated retaining wall structure. Background Art

[0002] In order to prevent the soil and gravel on both sides of the highway from rolling down and falling on the road surface, affecting safety, retaining walls are built to support the soil on both sides to avoid landslides on both sides, stabilize the embankment and cutting slopes, reduce earthwork volume, and prevent water from eroding the roadbed.

[0003] At present, the retaining walls commonly used in highways are generally constructed by integrally pouring concrete, and are generally retaining walls cast with wooden formwork. The method of making a concrete retaining wall is: first, dig a foundation trench on site, then lay a cushion layer, and after the cushion layer is laid, support the formwork and erect steel bars on site, and finally cast the wall with concrete. Since the wall of the concrete retaining wall structure is a whole cast wall, when making the wall, it is necessary to wait until the steel bars are erected before pouring. The entire construction period is relatively long, which has a greater impact on the progress of highway construction. Summary of the invention

[0004] The present invention relates to an integrated retaining wall structure, which designs a prefabricated retaining wall into an arc shape. When the inner side of the prefabricated retaining wall is subjected to soil thrust, the force is better transmitted to the left and right prefabricated columns, thereby reducing the deformation amplitude of the prefabricated retaining wall and ensuring the stress strength of the prefabricated retaining wall itself. The prefabricated columns and the prefabricated retaining wall are connected together by sliding and plugging, so that the connection between the prefabricated columns and the prefabricated retaining wall is simpler and faster, effectively shortening the construction time and reducing the construction difficulty.
