- Abstract:
- The composite soil nailing wall, new underground continuous wall and row pile supporting (pile anchor, pile support, double row piles, “pile wall one”), reverse building method, “zero space” foundation pit supporting method adjacent to the buildings, freezing method, combined support (soil nailing wall + pile anchor, soil nailing wall + pile support, soil nailing wall + underground continuous wall, etc.) in deep foundation pit support were summarized and analyzed. The new underground continuous wall, including “two walls in one” underground continuous wall, trench cutting remixing deep (TRD) method, cutter soil mixing (CSM) method, soil mixing wall (SMW) method, wall made of steel piles (WSP) method, continuous wall using recycled mud (CRM) method, TRUST method, prefabricated underground diaphragm wall, and prestress steel tube concrete supporting structure supporting pile wall, were emphatically analyzed. The characteristics, application scopes and applications of new technologies, new processes and new methods for existing deep foundation pit supporting were summarized. The problems that should be paid attention to when using new technology and new technology were proposed, and the future development trend and research direction of new deep foundation pit supporting technology were analyzed and prospected. The conclusion can provide guidance and reference for the development of deep foundation pit supporting technology and engineering design and construction.
