Anti-crack waterproof construction process for post-cast strip of basement exterior wall
The invention discloses an anti-crack waterproof construction process for a post-cast strip of a basement exterior wall, and belongs to the technical field of building construction. The anti-crack waterproof construction process comprises the following steps of 1, welding a steel bar framework by adopting phi 8 steel bars, and fixing a dense-hole steel wire mesh on the steel bar framework by using binding wires to manufacture dense-hole steel wire mesh frames; 2, the dense-hole steel wire net frames and water stop steel plates on the two sides of the post-cast strip are installed; 3, common waterproof concrete construction is conducted on the two sides of the post-cast strip of the basement exterior wall; 4, after the common waterproof concrete on the two sides of the post-cast strip is cured, structural steel bars and horizontal tie anti-crack steel bars in the post-cast strip are cleaned and adjusted; 5, after the strength of a painted leveling layer meets the design requirement, a coiled material is constructed for waterproofing; and 6, micro-expansion waterproof concrete with the strength improved by one grade compared with that of the common waterproof concrete on the two sides is adopted for pouring the post-pouring strip and the space on the inner side of a retaining wall. The method is easy to operate, effectively solves the problems of large potential safety hazards, resource waste and the like of traditional construction, and reduces the construction cost.
本发明公开了一种地下室外墙后浇带抗裂防水施工工艺，属于建筑施工技术领域。本发明的步骤为：步骤一：采用ф8钢筋焊接钢筋骨架，密孔钢丝网用扎丝固定在钢筋骨架上制作密孔钢丝网架；步骤二：安装后浇带两侧密孔钢丝网架和止水钢板；步骤三：进行地下室外墙后浇带两边普通防水混凝土施工；步骤四：后浇带两侧普通防水混凝土养护完成后，清理调整后浇带内结构钢筋和水平拉结抗裂钢筋；步骤五：粉刷找平层强度达到设计要求后施工卷材防水；步骤六：采用比两侧普通防水混凝土强度提高一个等级的微膨胀防水混凝土浇筑后浇带及挡土墙内侧的空间。本发明操作简易，有效地解决传统施工安全隐患大，资源浪费等问题，降低施工成本。
