Double-row SMW construction method pile foundation pit supporting structure and construction method thereof
The invention provides a double-row SMW construction method pile foundation pit supporting structure. The double-row SMW construction method pile foundation pit supporting structure comprises a first cement soil mixing pile supporting wall close to a foundation pit and a second cement soil mixing pile supporting wall away from the foundation pit, the two cement soil mixing pile supporting walls are formed by sequentially overlapping first cement soil mixing piles in a lap joint mode, H-shaped steel is inserted into the first cement soil mixing piles, the two cement soil mixing pile supporting walls are connected through a plurality of rigid connecting pieces, a plurality of mixing pile walls are arranged on the side, away from the foundation pit, of the second cement soil mixing pile supporting wall, the mixing pile walls are formed by overlapping second cement soil mixing piles in a lap joint mode, H-shaped steel is inserted into the second cement soil mixing piles, and the two ends of the mixing pile walls are connected with the second cement soil mixing pile supporting wall to form a partition bin. According to the double-row SMW construction method pile foundation pit supporting structure, a leakage point can be quickly found to accelerate the construction water stopping speed, and meanwhile, the strength of the SMW construction method pile can be improved to adapt to larger excavation depth.
本发明提供了一种双排SMW工法桩基坑支护结构，包括靠近基坑设置的第一水泥土搅拌桩支护墙和远离基坑设置的第二泥土搅拌桩支护墙，上述两个水泥土搅拌桩支护墙都由第一水泥土搅拌桩依次重叠搭接而成，所述第一水泥土搅拌桩内插有H型钢，上述两个水泥土搅拌桩支护墙通过若干个刚性连接件连接，所述第二水泥土搅拌桩支护墙远离基坑的一侧设有若干个搅拌桩墙，所述搅拌桩墙由第二水泥土搅拌桩重叠搭接形成，第二水泥土搅拌桩内插有H型钢，所述搅拌桩墙的两端与第二水泥土搅拌桩支护墙连接，形成分隔仓。本发明能迅速找到渗漏点以加快施工止水速度，同时也可以提高SMW工法桩强度以适应更大开挖深度。
