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

Abstract

The invention discloses a method and a structure for constructing a permanent soil-nailed 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; holes are drilled in the retaining wall formed by the woven fabric bags filled with the soil, soil-nailed steel bars and grouting pipes are arranged in the drilled holes, the grouting is carried out by the grouting pipes, 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 is applied in emergency repair projects and 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 grouting, the hole drilling 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 project time is short, thereby being capable of meeting the time need of the emergency repair projects. 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 geotextile bag soil nail retaining wall, and belongs to the technical field of retaining wall construction. Background technique [0002] Retaining wall is a kind of earth retaining structure widely used in many industries such as highway, water conservancy, railway, mine and urban 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 according to the construction materials: mortar masonry retaining wall and reinforced concrete retaining wall. Generally, there are the following disadvantages: [0003] Building retaining walls often takes a long time, requires cement, requires building materials, and some require certain mechanical equipment. [0004] During the construction period, it cannot be put into use, and it cannot b...

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
