Abstract

The invention relates to a construction method of a recyclable soil nail split mounting type flexible surface layer wall. The construction method is characterized in that the construction method comprises the steps that a soil nail, a flexible surface layer and a transverse contact body are manufactured, a foundation pit slope surface is dressed and grooved, the transverse contact body is placed,a special tool is used for screwing the soil nail into a soil layer, slope body drainage construction is conducted, an assembly type flexible surface layer is mounted, the end part of the soil nail isfixed, and materials are recycled and material turnover is conducted. According to the construction method of the recyclable soil nail split mounting type flexible surface layer wall, a split mounting type flexible surface layer is mounted on the end part of the soil nail to form a reliable transmission connection structure, after foundation pit construction is finished, the assembled flexible composite material surface layer, the soil nail, transverse contact angle steel and the like are removed to use circularly in the follow-up project, hole formation and grouting are conducted, drilling hole formation, mud protection wall, grouting and other construction steps are reduced, the construction efficiency is improved, mud contamination is avoided, the quality is reliable, and the construction quality is easy to ensure and control.

Description

technical field [0001] The invention relates to foundation pit support in the foundation pit excavation process, and also relates to temporary side slope support, in particular to a recyclable soil nail assembled flexible surface wall and a construction method. Background technique [0002] Soil nail wall support is a commonly used support technology in foundation pit engineering. The traditional soil nail wall support structure, such as the soil nail wall support structure disclosed in the Chinese patent application number 201820328989.2, has a technical solution that includes The soil nails are installed on the slope of the foundation pit at fixed intervals. The slope of the foundation pit is pierced with several wooden piles at intervals. The wooden piles are vertically arranged, and the wooden piles are attached to the corresponding soil nails. The soil nails are fixedly connected with the wooden piles, the slope of the foundation pit is laid with hanging nets, the woode...
