Double-C-shaped diaphragm wall joint structure and construction method
The invention discloses a double-C-shaped anti-seepage wall connector structure and a construction method. The construction method comprises the steps of groove wall reinforcement, guide wall construction, transverse short wall construction, first-stage anti-seepage wall construction and second-stage anti-seepage wall construction. Before first-stage and second-stage diaphragm wall construction is carried out, transverse short walls are firstly constructed; during first-stage diaphragm wall construction, longitudinal wall concrete is cut; during construction of the second-stage diaphragm wall, transverse short wall concrete and first-stage diaphragm wall concrete are cut, and finally the C-shaped connector is formed. According to the method, the transverse short wall is pre-constructed, seepage paths are remarkably increased, the split phenomenon caused by perpendicularity deviation of the wall body of the second-stage diaphragm wall is avoided, and therefore the waterproof and water stopping effects of the diaphragm wall are greatly improved.
本发明公开了一种双C形防渗墙接头结构及施工方法，包括槽壁加固、导墙施工、横向短墙施工、一期防渗墙施工和二期防渗墙施工；在进行一期和二期防渗墙施工前，先施工横向短墙；在一期防渗墙施工时切削纵墙混凝土；在二期防渗墙施工时切削横向短墙混凝土及一期防渗墙混凝土，最终形成C形接头。本发明通过预施工横向短墙，显著增加了渗流路径，并避免二期防渗墙墙体因垂直度偏差导致的劈叉现象，从而大幅提升防渗墙的防水和止水效果。
