Waterproof method and waterproof structure for pile foundation underpinning underground storey-adding basement
The invention provides a waterproof method and a waterproof structure for a pile foundation underpinning underground storey-adding basement, and relates to the technical field of underground storey-adding. The pile foundation underpinning underground storey-adding basement aims to solve the problem that the waterproof structure of the basement after underground storey-adding at present is easy to lose efficacy. The waterproof structure is arranged at the bottom of a pile hole in advance, an underpinning pile body is poured under the wrapping action of the waterproof structure, after a foundation pit is excavated, part of the waterproof structure is peeled off to be in lap joint with a waterproof layer in the foundation pit into a whole, the waterproof layer of the basement structure is integrally wrapped, underground water is effectively isolated, and the leakage problem is solved.
本发明提供一种桩基托换地下增层地下室防水方法及防水结构，涉及地下增层技术领域，针对目前地下增层后地下室防水结构容易失效的问题，通过在桩孔底部预先布置防水结构，在防水结构包裹作用下浇注托换桩体，并在开挖基坑后剥离部分防水结构使其与基坑内防水层搭接为一体，达到对地下室结构防水层的整体包裹，有效隔离地下水解决渗漏问题。
