Construction method for plugging split bolt hole of shear wall
The invention discloses a construction method for plugging a split bolt hole of a shear wall. The construction method comprises the following steps that S1, hole cleaning treatment is conducted; S2, an exposed PVC pipe is chiseled out; S3, flushing and wetting are conducted; S4, the outer side of the wall is plugged, specifically, an outer cement plug is wrapped with polymer cement waterproof mortar and plugged into or hammered into a hole channel of the split bolt hole from outside to inside from the outer wall, and the polymer cement waterproof mortar is used for conducting plugging and compacting; S5, the inner side of the wall is plugged, specifically, an inner cement plug wrapped with the polymer cement waterproof mortar is plugged into the inner side of the split bolt hole; S6, grouting is conducted on the inner side of the wall, specifically, a glue gun is adopted for grouting construction, a mortar outlet of the glue gun is inserted into a grouting through hole of the inner cement plug, and the polymer cement waterproof mortar is injected into the split bolt hole; and S7, cleaning is conducted, specifically, after the mortar is finally set, a scraper knife is used for scraping away redundant laitance on the periphery of the bolt hole. According to the construction method, the mode that the cement plugs and the polymer cement waterproof mortar are matched for plugging is adopted for plugging, and the problem that the mortar at the two ends of the split bolt hole is prone to cracking and falling off is avoided.
本发明公开了一种剪力墙对拉螺栓孔封堵施工方法，包括以下步骤：S1、清孔处理；S2、凿除外露PVC管；S3、冲洗湿润；S4、墙外侧封堵：使用聚合物水泥防水砂浆包裹外水泥塞从外墙由外向内塞入或锤入对拉螺栓孔的孔道中，用聚合物水泥防水砂浆封堵密实；S5、墙内侧封堵：在对拉螺栓孔的内侧塞入聚合物水泥防水砂浆包裹的内水泥塞；S6、墙内侧注浆：采用胶枪进行注浆施工，将胶枪出浆口插入内水泥塞的注浆通孔中，向对拉螺栓孔中注入聚合物水泥防水砂浆；S7、清理：待浆液终凝后，利用铲刀将螺栓孔眼周侧多余的浮浆铲除；本发明采用水泥塞与聚合物水泥防水砂浆配合封堵的方式进行封堵，避免了对拉螺栓孔两端砂浆容易开裂、脱落的问题。
