Construction method for accelerating cutting of waist beam in foundation pit supporting concrete
The invention relates to a construction method for accelerating cutting of a foundation pit support concrete inner waist beam, belongs to the technical field of building construction, and aims at solving the problem that in the construction process of high-rise buildings in coastal areas, the construction cost is reduced due to the fact that steel pipe piles and steel sheet piles are combined together through lock catches to form a support structure, and the soil retaining and water stopping effects are achieved. Soft soil deep foundation pit supporting is really a challenging technical problem. Soft soil has lower shear strength and higher compressibility, so that the strength and rigidity of a supporting structure are difficult to meet the requirements, and the supporting stability becomes a key problem. And meanwhile, the rheological property and the space-time effect of the soft soil also have obvious influence on the deformation of the deep foundation pit, so that the deformation control difficulty is increased.
本发明涉及一种加快切割基坑支护混凝土内腰梁的施工方法，属于建筑施工技术领域，利用锁扣将钢管桩及钢板桩组合在一起形成支护结构，起到挡土与止水的作用，解决了在沿海地区的高层建筑施工过程中，软土深基坑支护确实是一个具有挑战性的技术问题。由于软土具有较低的抗剪强度和较高的压缩性，这使得支护结构的强度和刚度难以满足要求，支护稳定性成为一个关键问题。同时，软土的流变性和时空效应也会对深基坑的变形产生显著影响，使得变形控制难度加大的问题。
