Construction method for eliminating inner side construction joint of underground structure outer wall
The invention relates to a construction method for eliminating an inner side construction joint of an underground structure outer wall. The construction method comprises the following steps that bottom plate steel bars are bound, and after the bottom plate steel bars are bound, wall plate steel bars are inserted; the steel bars are welded and fixed to be used for installing a water stop steel plate; steel bars are welded to the upper portion of the water stop steel plate for reinforcement; a steel wire net is arranged on wall plate vertical stress steel bars to be connected with the bottom plate steel bars; a formwork is hung to be installed; correction is conducted, and after the side corners of the formwork are straight, concrete pouring is conducted after the formwork is reinforced; formwork removal is conducted, after formwork removal is completed, upper layer wall plate steel bar binding is conducted, a wall plate inner side formwork is installed, the bottom of the formwork directly falls on a bottom plate, an outer side formwork is erected along the construction joint, after the formwork is installed, reinforcement is conducted, concrete pouring is conducted after perpendicularity is corrected, and vibration is reinforced in the pouring process; and formwork removal is conducted. The outer wall construction joint is eliminated, the appearance quality of concrete is improved, the waterproof performance of an underground structure is enhanced, and the later-period maintenance cost is reduced.
本发明涉及一种消除地下结构外墙内侧施工缝接茬的施工方法，包括如下步骤：底板钢筋绑扎，底板钢筋绑扎完成后，再插入墙板钢筋；焊接固定钢筋用来安装止水钢板；在止水钢板上部再焊接钢筋进行加固；在墙板竖向受力钢筋上设置钢丝网与底板钢筋连接；吊模模板安装；进行校正，保证模板边角顺直后，对模板加固后进行混凝土浇筑；拆模，拆模完成后进行上层墙板钢筋绑扎，安装墙板内侧模板，模板底部直接落在底板上，外侧模板沿施工缝进行支设，模板安装完成后进行加固，校正垂直度后混凝土浇筑，浇筑过程加强振捣；拆模；本发明消除外墙施工缝接茬，提高混凝土外观质量，增强地下结构防水性能，减少后期维护费用。
