Waterproof joint structure of prestressed anti-floating anchor rod and construction method of waterproof joint structure
The waterproof joint structure comprises an anchor plate, a foundation trench of a foundation pit is communicated with a water collecting well of the foundation pit, a plurality of anchor rod holes are formed in the bottom of the foundation trench, and the anchor plate is laid at the bottom of the foundation trench and blocks the anchor rod holes; the anti-corrosion sleeve is vertically arranged in the foundation trench, the anti-corrosion sleeve is connected to the penetrating hole of the anchoring plate, a water stop ring plate is formed outside the anti-corrosion sleeve, the upper end of the anti-corrosion sleeve is connected with an end sealing plate, a through hole is formed in the end sealing plate, and the prestressed tendon in the anchor rod hole penetrates through the anti-corrosion sleeve and the through hole and extends to the position above the pit bottom; the cushion layer is poured in the pit bottom and the foundation trench; the advanced waterproof coiled material is laid on the cushion layer in the foundation trench, the outer edge of the advanced waterproof coiled material extends to the cushion layer on the pit bottom, and the inner side of the advanced waterproof coiled material is upturned to cover the lower part of the anti-corrosion sleeve; the foundation trench is filled with the closed concrete, the concrete wraps the anti-corrosion sleeve, and conventional waterproof coiled materials are laid on the cushion layer of the pit bottom and the closed concrete. The problem that the bottom plate is prone to leakage due to post-tensioning of the prestressed anti-floating anchor rod is solved.
本发明公开了一种预应力抗浮锚杆的防水节点构造及其施工方法，包括：锚固板，基坑的基槽连通于基坑集水井，基槽的槽底形成有多个锚杆孔，锚固板铺设于基槽的槽底且封堵于锚杆孔；竖向设置于基槽中的防腐套筒，防腐套筒连接于锚固板的穿孔，防腐套筒的外部形成有止水环板，防腐套筒的上端连接有封端板，封端板开设有贯孔，锚杆孔中的预应力筋穿设于防腐套筒和贯孔并伸至坑底的上方；垫层，浇筑于坑底和基槽中；超前防水卷材，铺设于基槽中的垫层上，超前防水卷材的外缘延伸至坑底上的垫层，超前防水卷材的内侧上翻包覆于防腐套筒的下部；封闭混凝土，填充于基槽内，混凝土包覆于防腐套筒，坑底的垫层和封闭混凝土上铺设有常规防水卷材。本发明解决了预应力抗浮锚杆后张拉易导致底板渗漏的问题。
