Construction method of river-crossing foundation pit support
The invention particularly relates to a construction method of a river-crossing foundation pit support. Comprising a steel sheet pile cofferdam; the cofferdam base is thoroughly removed; occluded steel sheet piles are constructed; constructing a foundation pit support; constructing a waterproof curtain and fender posts by adopting three-axis cement mixing piles and inserting profile steel; latticed column construction is conducted, cast-in-situ bored pile construction is adopted, and latticed columns and middle supporting piles used for foundation pit supporting are inserted; the double-shaft stirring pile is constructed and used for reinforcing soil bodies of the whole foundation pit and the cofferdam; and supporting construction. According to the method provided by the invention, the construction safety of the foundation pit in the riverway area is ensured, the construction progress of the foundation pit in the riverway area is improved, a reliable technical scheme is provided for the construction safety of the foundation pit, and the environment around the riverway is ensured.
本发明具体是一种跨河道基坑支护的施工方法；包括钢板桩围堰；对围堰基底彻底清除；咬合钢板桩施工；基坑围护施工；采用三轴水泥搅拌桩加插型钢进行止水帷幕和围护桩施工；格构柱施工，采用钻孔灌注桩施工，插入格构柱，用于基坑支护的中间支撑桩；双轴搅拌桩施工，用于整个基坑和围堰的土体加固；支撑施工。本发明所提出的此种方法，确保了河道区域基坑施工的安全，提高了河道区域基坑施工的进度，为基坑的施工安全提供了可靠的技术方案，保证了河道周边的环境。
