Anti-pulling pile head node waterproof structure serving as temporary stand column and construction method
The invention discloses an anti-pulling pile head node waterproof structure serving as a temporary stand column and a construction method, and relates to the technical field of underground engineering such as house buildings, rail transit and municipal engineering. An anti-pulling pile is arranged and also serves as the temporary stand column, a rectangular post-pouring hole is formed in the position, at the anti-pulling pile, of a structural bottom plate, a rectangular tongue-and-groove is formed in the position, at the rectangular post-pouring hole, of the structural bottom plate, an annular first water swelling water stop strip is embedded in the middle of the rectangular tongue-and-groove, and an annular L-shaped grouting pipe is embedded in the lower portion of the rectangular tongue-and-groove. The waterproof problem of an anti-pulling pile head node also serving as the temporary stand column can be solved, the water interception effect during construction is good, the waterproof effect during use is good, and the durability is high; a reinforced concrete cushion layer and grouting pipes embedded below the cushion layer can ensure that the waterproof node is good in water interception effect during construction, tongue-and-groove water stop glue and the tongue-and-groove annular L-shaped grouting pipe can ensure that the waterproof node is good in waterproof effect during use, and the waterproof node is provided with a plurality of water interception and waterproof systems.
本发明公开是关于一种兼做临时立柱的抗拔桩桩头节点防水结构及施工方法，涉及房屋建筑、轨道交通、市政工程等地下工程技术领域。设置有抗拔桩，该抗拔桩兼做临时立柱，结构底板在抗拔桩位置设矩形后浇孔洞，该矩形后浇孔洞位置的结构底板处设矩形企口，所述矩形企口中间位置埋设环向第一遇水膨胀止水条，矩形企口下部位置埋设环向L形注浆管。本发明可以解决兼做临时立柱的抗拔桩桩头节点防水难题，施工期间截水效果好，使用期间防水效果好，耐久性能强。钢筋混凝土垫层和垫层下方预埋注浆管可以确保该防水节点在施工期间截水效果好，企口止水胶和企口环向L形注浆管可以确保该防水节点在使用期间防水效果好，本防水节点设置多道截水和防水体系。
