CAO JIALIN / LI XIAOWEI / PAN FEI

The invention discloses a pile head waterproof structure and a pile head waterproof construction method. The pile head waterproof structure comprises a pile body arranged on a pile head and a first waterproof coating layer arranged on the top of the pile head. The concrete cushion layer is arranged on the periphery of the pile body; the continuous first non-cured waterproof layer is positioned on the upper surface of the concrete cushion layer; the waterproof coiled material layer is positioned on the upper surfaces of the pile body and the first non-cured waterproof layer; the second non-continuous non-cured waterproof layer is positioned on the upper surface of the waterproof roll layer; the protective layer is positioned on the upper surfaces of the second non-cured waterproof layer and part of the waterproof roll layer; the concrete cushion layer comprises a first groove adjacent to the pile body and a second groove at least 500 mm away from the edge of the pile body in the horizontal direction. And the waterproof roll layer is bent in the first groove and the second groove. According to the pile head waterproof structure, the problem that the waterproof coiled material is torn due to sedimentation is effectively solved, and therefore the waterproof effect of the pile head is remarkably improved.

本发明公开了一种桩头防水结构及桩头防水的施工方法，该桩头防水结构包括设置在桩头的桩身和桩头的顶部的第一防水涂料层；设置在桩身四周的混凝土垫层；位于混凝土垫层上表面的连续的第一非固化防水层；位于桩身和第一非固化防水层上表面的防水卷材层；位于防水卷材层的上表面的非连续的第二非固化防水层；位于第二非固化防水层和部分的防水卷材层的上表面的保护层；其中，所述混凝土垫层包括紧邻桩身的第一凹槽和水平方向上距离桩身边缘至少500mm的第二凹槽；防水卷材层在第一凹槽和第二凹槽呈弯曲状。该桩头防水结构有效地改善了因沉降导致的防水卷材撕裂问题，从而显著提高桩头处的防水效果。
