Foundation pit bottom plate inrush-preventing and crack-resisting structure and construction method thereof
The invention discloses an anti-inrush and anti-crack structure of a foundation pit bottom plate and a construction method of the anti-inrush and anti-crack structure. The structure comprises a first bottom plate layer (1), a second bottom plate layer (2), a water stop steel plate (3) and vertical connecting ribs (4). The first bottom plate layer is poured and constructed at the bottom of a foundation pit (5), and the second bottom plate layer is poured and constructed at the top of the first bottom plate layer, so that a horizontal layered pouring bottom plate structure is formed; a horizontal construction joint is formed between the first bottom plate layer and the second bottom plate layer; the multiple water stop steel plates are arranged at the horizontal construction joints at intervals, one ends of the multiple vertical connecting ribs are inserted into the first bottom plate layer, and the other ends of the multiple vertical connecting ribs extend to the position above the first bottom plate layer and are inserted into the second bottom plate layer. The problems that in the prior art, the exposure time of a base is long, so that sudden gushing is caused, and a super-thick bottom plate is prone to cracking through one-time pouring can be solved.
本发明公开了一种基坑底板防突涌和抗裂构造及其施工方法，该构造包括第一底板层(1)、第二底板层(2)、止水钢板(3)和竖向连接筋(4)；第一底板层浇筑施工在基坑(5)的底部，第二层底板层浇筑施工在第一底板层的顶部，形成水平分层浇筑底板结构；第一底板层与第二底板层之间形成水平施工缝；若干块止水钢板分别间隔设置在水平施工缝处，若干根竖向连接筋的一端插入在第一底板层内，若干根竖向连接筋的另一端延伸至第一底板层的上方并插入在第二底板层内。本发明能够解决现有技术中基底暴露时间长而导致突涌以及超厚底板一次性浇筑容易开裂的问题。
