Waterproof structure of tensioning end of prestressed anti-floating anchor rod and construction method of waterproof structure
The invention discloses a waterproof structure of a tensioning end of a prestress anti-floating anchor rod and a construction method of the waterproof structure of the tensioning end of the prestress anti-floating anchor rod. A first sealing strip, a waterproof layer and a polyurethane layer are used for constructing a first waterproof measure at the junction of a concrete consolidation body of the anti-floating anchor rod and a cushion layer, and a waterproof coiled material and a composite asphalt layer are used for constructing a second waterproof measure at the junction of the cushion layer and a supporting sleeve. A water stop wing ring of a supporting sleeve serves as a third waterproof measure in a bottom plate, finally, a post-pouring groove is formed in the upper portion of the bottom plate, sealing grease, a polyurethane layer and a steel cover are used for building a fourth waterproof measure, the steel cover is sealed with expansive concrete, and waterproof blocking is conducted on an anti-floating anchor rod through the four waterproof measures in the vertical direction. And the water seepage hidden danger of the anti-floating anchor rod is effectively reduced. The anti-floating anchor rod solves the problems that an existing anti-floating anchor rod is poor in waterproof effect, and the phenomenon of water seepage of anchor rod reinforcing steel bars occurs occasionally.
本发明公开了一种预应力抗浮锚杆的张拉端的防水构造及其施工方法，本发明的预应力抗浮锚杆的张拉端的防水构造的施工方法，通过在抗浮锚杆的混凝凝土固结体与垫层之间的交界处利用第一密封条、防水层、聚氨酯层构建第一道防水措施，于垫层与支撑套管的交接处设置利用防水卷材、复合沥青层构建第二防水措施，利用支撑套管的止水翼环作为底板中的第三道防水措施，最后在底板的上部形成后浇槽，利用密封油脂、聚氨酯层、钢罩构建第四道防水措施，再辅以膨胀混凝土封闭钢罩，通过竖向方向上的四道防水措施，对抗浮锚杆进行防水封锁，有效降低抗浮锚杆的渗水隐患。本发明解决了现有的抗浮锚杆的防水效果不佳，锚杆钢筋渗水现象时有发生的问题。
