Method for supporting special-shaped foundation pit of pump station
According to the method for supporting the special-shaped foundation pit of the pump station, the special-shaped foundation pit of the pump station is constructed in the sludge land beside the river channel, the one-way supporting frames, the two-way supporting frames and the lengthened supporting frames are installed on the supporting piles in the foundation pit, and therefore the interiors of the steel sheet piles can be effectively supported; and the inner support pressure of each point is adjusted in real time through pressure parameters returned by each oil cylinder, so that pit collapse caused by over-driving or over-small pressure in the steel sheet pile is prevented, the construction safety is improved, and the problem that when a special-shaped foundation pit is constructed under the silt geological condition beside a river channel, the construction cost is reduced is solved. And the steel sheet pile deforms towards the inner side due to the pressure of the sludge land, and the internal pressure and the external pressure borne by the steel sheet pile are not uniform.
本发明提供一种泵站异型基坑支护方法，本方法在河道旁的淤泥地中施工异型的泵站基坑，通过在基坑内的支撑桩上安装单向撑架、双向撑架和加长撑架，能够对钢板桩的内部进行有效支撑，并通过各油缸传回的压力参数对各点的内撑压力进行实时调节，防止钢板桩内部的压力过打或者过小导致的溃坑，提高了施工的安全性，解决了在河道旁淤泥地质条件下进行异型基坑施工时，钢板桩会受到淤泥地的压力导致钢板桩会向内侧变形且钢板桩所受内外压力不均匀的问题。
