Construction method for rebuilding existing building basement outer wall
The invention discloses a construction method for rebuilding an existing building basement outer wall. The construction method comprises the steps that S1, an upper wall body of the existing buildingbasement outer wall is dismantled, and a first joint surface is formed; S2, a steel bar protection layer on one side of the upstream face of the existing building basement outer wall is stripped, a second joint face is formed, the first joint face is connected with the second joint face, and the second joint face is located below the first joint face; S3, water swelling sealing strips are installed on the first joint surface and the second joint surface; and S4, starting from the first joint face and the second joint face, construction of a newly-built wall is conducted. According to the method, by prolonging a water seepage path and adopting conventional waterproof materials such as conventional impermeable concrete and the water swelling sealing strips, the water-stop steel plate type waterproof effect of a newly-built engineering construction joint can be achieved. Compared with a conventionally adopted post-grouting leaking stoppage method, the construction method belongs to pre-control, the structure construction method is simple and convenient, and the cost is low.
本发明公开一种既有建筑地下室外墙再建的施工方法，包括步骤：S1、拆除既有建筑地下室外墙的上部墙体，形成第一接缝面；S2、剥离既有建筑地下室外墙的迎水面一侧的钢筋保护层，形成第二接缝面，第一接缝面与第二接缝面相接且第二接缝面处于第一接缝面的下方；S3、在第一接缝面和第二接缝面分别安装遇水膨胀止水条；S4、由第一接缝面和第二接缝面开始，进行新建墙体的施工。本申请中，通过延长渗水路径，采用常规抗渗混凝土及遇水膨胀止水条等常规防水材料，便可达到新建工程施工缝止水钢板式的防水效果；与常规采用的事后灌浆堵漏方法相比，本施工方法属于事前控制，且结构施工方法较为简便，成本也较低。
