How to do a good job in deep foundation pit engineering? The overall benefits are better

The surrounding environment of the foundation pit of the fourth phase of Kunshan Yangcheng Lake Science Park Industrial Technology Research Institute is complex, the excavation area is large, the depth is deep, and the construction is difficult. By adopting the innovative technical scheme of Shanghai Qiangqiang Foundation Engineering Co., LTD. (hereinafter referred to as "Shanghai Qiangqiang Foundation"), on the basis of saving the construction period and cost, the maximum survey of the slope is not more than 2cm, and the comprehensive benefit is far better than that of the traditional concrete support scheme.

Prestressed steel composite support can be recycled

Prestressed steel composite support compared with traditional concrete support, because is to use steel component assembly, don't need to carry on the in situ conservation, in the last stage, the steel members is also more convenient dismantling is reinforced concrete, shorten construction period, reduce the construction noise, and steel component reuse, recycle to reduce the cost, Meet the environmental requirements of energy conservation and emission reduction.

The prestress of a composite brace of prestressed steel sections

Compared with the traditional steel composite bracing, prestressed steel composite bracing increases the construction procedure of applying prestress. The steel support of prestressed fish-belly foundation pit adopts special fish-belly beam structure. Under the premise of ensuring the construction quality, it further reduces the number of steel components, provides a more open construction space, makes the construction of earth digging, earth transport and underground structure more convenient, improves the construction period as a whole, and reduces the cost at the same time.
