Construction method of double-layer geomembrane composite diaphragm wall
The invention discloses a construction method of a double-layer geomembrane composite anti-seepage wall, and aims to provide a construction method which can effectively solve the problems of geomembrane distortion and floating in the construction process of the geomembrane composite anti-seepage wall in the prior art. The construction method of the double-layer geomembrane composite anti-seepage wall can effectively improve the blocking effect of the geomembrane composite anti-seepage wall. The method sequentially comprises the following steps that A, an anti-seepage wall groove is constructed, specifically, TRD equipment is adopted for cutting and stirring in a foundation to form the anti-seepage wall groove; b, a double-layer geomembrane is laid, the geomembrane is lowered in a U shape, the U-shaped geomembrane comprises a left-layer side geomembrane, a right-layer side geomembrane and a bottom geomembrane connecting the bottoms of the left-layer side geomembrane and the right-layer side geomembrane into a whole, a balance weight piece is placed at the bottom of the geomembrane, and the bottom end of the geomembrane sinks to the groove bottom of the diaphragm wall groove under the gravity action of the balance weight piece; and C, the backfill material is sprayed and stirred, the filler is poured between the left-layer side geomembrane and the right-layer side geomembrane, and the double-layer geomembrane composite diaphragm wall is formed.
本发明公开了一种双层土工膜复合防渗墙施工方法，旨在提供一种不仅能够有效解决现有技术中的土工膜复合防渗墙在施工过程中存在的土工膜扭曲和漂浮问题；而且还能够有效提高土工膜复合防渗墙的阻隔效果的双层土工膜复合防渗墙施工方法。它依次包括以下步骤：A，施工防渗墙槽，采用TRD设备在地基内切割搅拌形成防渗墙槽；B,铺设双层土工膜，土工膜呈U型下放，呈U型的土工膜包括左右两层侧土工膜及将左右两层侧土工膜底部连为一体的底部土工膜，土工膜底部放置配重件，土工膜底端在配重件的重力作用下沉到防渗墙槽的槽底；C，喷浆搅拌回填料，在左右两层侧土工膜之间灌注填充料，形成双层土工膜复合防渗墙。
