Method and structure for constructing permanent retaining wall by woven fabric bags filled with soil

Abstract

The invention discloses a method and a structure for constructing a permanent retaining wall by woven fabric bags filled with soil. The invention is characterized in that the soil is firstly taken and filled in woven fabric bags to obtain the woven fabric bags filled with the soil, then the woven fabric bags filled with the soil are arranged for filling to obtain a retaining wall formed by the woven fabric bags filled with the soil, then a shock tube is arranged in the retaining wall formed by the woven fabric bags filled with the soil, cement slurry or cement mortar is injected into the shock tube, and a reinforced concrete surface layer is produced on the outside and the top of the retaining wall formed by the woven fabric bags filled with the soil, thereby obtaining the permanent retaining wall. The invention can carry out the phased construction, the part of forming the retaining wall by the woven fabric bags filled with the soil is firstly constructed, the road traffic is restored, the emergency disaster relief is completed, the shock tube and the concrete surface layer are further constructed after restoring to normal state, and the construction of the permanent retaining wall by the woven fabric bags filled with the soil is finally completed. The filling part of the woven fabric bags filled with the soil is taken as an effective component part of the permanent retaining wall and does not need to be removed, thereby saving engineering cost.

Description

technical field [0001] The invention relates to a method and structure for building a permanent retaining wall with geotechnical woven bags, and belongs to the technical field of retaining wall construction. Background technique [0002] Retaining wall is a kind of retaining structure widely used in many industries such as highway, water conservancy, railway, mine and town construction. According to the function of use, it can be divided into permanent retaining wall and temporary retaining wall. As far as the permanent retaining wall is concerned, it can be divided into two types: masonry rubble retaining wall and reinforced concrete retaining wall according to the construction materials. Generally, there are the following disadvantages: [0003] Building retaining walls often takes a long time, requires cement, and also requires building materials, and some require certain mechanical equipment. [0004] It cannot be put into use during the construction period, and it can...

AI Technical Summary

Problems solved by technology

Because the woven bag is easy to weather and age under the sunlight, and its durability is poor, this kind of geotechnical woven bag retaining wall is generally only used as a temporary emergency project, and it is often dismantled after a period of time after the emergency is completed, and the permanent retaining soil such as mortar masonry is rebuilt. wall, there is a phenomenon of project waste
