Project Overview:

The width of the foundation pit of this project is about 7.8~42.2m, and the depth of the foundation pit is about 0.2~14.5m. The local pump room is deep, and the depth of the foundation pit is 11.98~14.63m. The section jointly built with the Central Park Underground Ring Road, the depth of the foundation pit is 14.46m and 12.46m respectively, according to the depth of the foundation pit from shallow to deep, the enclosure adopts grading, Larsen steel sheet piles, ∅650@450 construction piles, ∅850@600 construction piles, ∅800@1000 bored piles and ∅1000 @1200 bored pile. The depth of the foundation pit in the grading section is 0.2~1.2m; the depth of the foundation pit in the Larsen steel sheet pile section is 1.2~4.5m, with 0~1 steel supports; the depth of the foundation pit in the ∅650@450 construction method pile section is 4~7.5m, with 1 concrete support +0/1 steel support; ∅850@600 construction method pile section foundation pit depth 7.0~10.5m, 1 concrete support +1~2 steel supports; ∅800@1000 bored piles are used for equipment rooms, A trestle is partially set up, and the depth of the foundation pit is 7~7.3m, supported by 2 lines of concrete; ∅1000@1200 bored piles are used for the pump room and the section co-constructed with the ring road, the depth of the foundation pit is 11.98~14.63m, and the ring road is co-constructed The section uses 3 concrete supports, and the pump room uses 1 concrete support + 2/3 steel supports.
