Method for building slope protection retaining wall during filling

Abstract

The invention discloses a method for building a slope protection retaining wall during filling. The method comprises the following steps of: a) levelling a slope and excavating a pit; b) integrally pouring a C10 concrete cushion on the slope and the bottom of the pit, and reserving holes corresponding to drain holes in a rear panel; c) integrally pouring a retaining wall structure by using reinforced concrete, wherein the retaining wall structure comprises a bottom plate, a faceplate, the rear panel, wall supporting plates, an extending panel and the like; and d) filling proper earth in the prepared retaining wall, and tamping layer by layer until the top of the slope. By the method, a defect that a foundation of the retaining wall is difficult to excavate can be effectively avoided, and the stability against overturning and slippage of the retaining wall is ensured by using the self gravity of the retaining wall filled with the earth, so that the engineering aim of easily, conveniently, safely and reliably constructing is fulfilled.

Description

technical field [0001] The invention relates to a construction fill slope protection technology, in particular to a construction method for a fill slope protection retaining wall. [0002] Background technique [0003] During road construction, when the road passes through a relatively low-lying road section, it is necessary to use filling engineering to fill up the roadbed and then lay the road surface. Filling refers to filling from the original ground to the surface of the roadbed when the surface of the roadbed is higher than the original ground. volume of rock. [0004] In filling works, in order to protect road safety and prevent slope collapse, it is necessary to set up retaining walls on the air side of the slope for protection. In traditional retaining wall structures, such as buttress-type retaining walls and gravity-type retaining walls, during the specific construction process of laying, it is necessary to cut the slope or dig out a relatively large portion of ...

AI Technical Summary

Problems solved by technology

One is that the engineering volume is large, the construction process is complicated, and the construction time is prolonged, which is difficult to implement in some difficult-to-excavate rock foundations or high-strength soil foundations; Stable and collapsed, causing safety hazards in the construction process

At the same time, with the existing slope protection technology, after the retaining wall is installed, the protective effect on the fill slope still needs to be improved.
