Waterproof structure at underground wall and construction method thereof
The invention provides a waterproof structure at an underground wall. The waterproof structure is formed between an existing bottom plate and a to-be-formed bottom plate of a foundation pit, a height difference exists between the to-be-formed bottom plate and the existing bottom plate, the end part of the existing bottom plate is constructed to form a side wall, and an enclosure wall is formed on one side, far away from the existing bottom plate, of the side wall. The waterproof structure comprises a waterproof layer laid below the existing bottom plate, and the protruding part of the waterproof layer is attached to the side face, close to the enclosure wall, of the side wall; a first backfill layer is filled between the side wall and the enclosure wall, and an upward inclined slope surface is formed on the top surface of the first backfill layer; the top of the enclosure wall is filled with a second backfill layer, and the waterproof layer is attached to the top face of the first backfill layer and the top face of the second backfill layer; and a third backfill layer is filled between the top of the first backfill layer and the side wall. The technical problem that the waterproof layer is prone to failing and being damaged in traditional construction is solved, the service life of the waterproof layer is prolonged, and the stability of the waterproof layer is improved.
本发明提供了一种地下墙体处的防水结构，防水结构形成于基坑的既有底板和待形成底板之间，待形成底板和既有底板之间具有高度差，既有底板的端部施工形成有侧墙，侧墙远离既有底板的一侧形成有围护墙，该防水结构包括：铺设于既有底板下方的防水层，防水层的凸伸部分贴合于侧墙靠近围护墙的侧面；填充于侧墙和围护墙之间的第一回填层，第一回填层的顶面形成有向上倾斜的坡面；填充于围护墙的顶部的第二回填层，防水层贴合于第一回填层和第二回填层的顶面；以及填充于第一回填层的顶部和侧墙之间的第三回填层。本发明解决了传统施工中防水层容易失效且容易被破坏的技术问题，提高了防水层的使用寿命和稳定性。
