Tower crane foundation hole advance water stop structure and construction system thereof
The invention relates to the technical field of building construction, in particular to a tower crane foundation hole advance water stop structure and a construction system thereof. Before a tower crane foundation hole is not closed, a tower crane foundation, a first bottom plate downward turning ring beam, a first water stop belt, a foundation upward turning ring beam, a second water stop belt and a second bottom plate downward turning ring beam are included, and the first bottom plate downward turning ring beam is arranged on the edge of the top of the tower crane foundation; a first water stop belt is embedded in the middle of the inner circumferential side face of the first bottom plate downward turning ring beam; a concave-convex buckled ring beam structure is utilized, namely, two downwards-turned ring beams of a basement bottom plate and one upwards-turned ring beam of a tower crane foundation are buckled with each other, and an n-shaped deformation joint is formed; in the gaps, BW type water swelling rubber waterstops and grouting flexible materials are buried, so that four flexible advanced waterstop layers are formed, the influence of settlement difference generated by different construction forms under different bottom plate foundations on the waterstop structure is avoided, and water permeation is prevented.
本发明涉及建筑施工技术领域，尤其涉及一种塔吊基础洞口超前止水结构及其施工体系。在塔吊基础洞口未封闭前，包括有塔吊基础，第一底板下翻圈梁，第一止水带，基础上翻圈梁，第二止水带和第二底板下翻圈梁，在塔吊基础的顶部边沿设置第一底板下翻圈梁；在第一底板下翻圈梁内周侧面中间位置埋设第一止水带；利用凹凸相扣的圈梁构造，即地下室底板下翻的两道圈梁与塔吊基础上翻的一道圈梁相互扣合，形成“几”字形变形缝；在这些缝隙中，通过埋设BW型遇水膨胀橡胶止水带和注浆柔性材料，形成了四道柔性超前止水层，避免了不同底板地基下构造形式不同产生的沉降差对止水结构的影响，防止水的渗透。
