Concrete diaphragm wall construction method
The invention discloses a concrete anti-seepage wall construction method in the field of water conservancy and hydropower engineering, which comprises the following steps of: firstly excavating a first-stage groove, mounting supporting templates on the left side and the right side in the first-stage groove, pouring the first-stage groove, then taking out the supporting templates, excavating a second-stage groove, mounting supporting templates on the left side and the right side in the second-stage groove, and pouring the second-stage groove. And after pouring, the supporting formwork is taken out, finally, pouring is conducted on the space reserved by the supporting formwork in the I-stage groove and the space reserved by the supporting formwork in the II-stage groove, and the wall sections of the I-stage groove and the wall sections of the II-stage groove are connected. The filling space is reserved between the wall sections of the I-stage groove and the wall sections of the II-stage groove through the first supporting formwork and the second supporting formwork, and meanwhile the end faces of the wall sections are bent, so that after concrete is poured into the filling space, the contact area between the adjacent wall sections can be increased, cracks penetrating through the anti-seepage wall are not prone to occurring at the wall section connecting positions, and the anti-seepage effect of the anti-seepage wall is improved. And meanwhile, the seepage path of the connecting part between the wall sections is increased, so that the seepage-proofing effect of the connecting part of the wall sections is improved.
本发明公开的是水利水电工程领域的一种混凝土防渗墙施工方法，包括以下步骤：先开挖Ⅰ期槽，在Ⅰ期槽内的左右两侧安装支撑模板，对Ⅰ期槽进行浇筑，之后取出支撑模板，然后开挖Ⅱ期槽，在Ⅱ期槽内的左右两侧安装支撑模板，浇筑后再取出支撑模板，最后对Ⅰ期槽和Ⅱ期槽中的支撑模板留下的空间进行浇注，对Ⅰ期槽和Ⅱ期槽的墙段进行连接。本发明利用第一支撑模板和第二支撑模板在Ⅰ期槽和Ⅱ期槽的墙段之间留出填充空间，同时对墙段端面做曲折处理，使得在该填充空间浇注混凝土后，能增大相邻墙段之间的接触面积，使得墙段连接部位更不容易出现贯穿防渗墙的裂缝，同时增大了墙段之间连接部位的渗径，从而提高了墙段连接部位的防渗效果。
