It proves that a series of difficulties will be overcome in using the eccentric DTH hammer drilling with casing hole ＋ PVC tube wall construction and local double-row pile construction technology, as well as the upper and lower inner pile anchor support system of the underground substation chamber in deep foundation pit in the adjacent sea 35kV to en- sure the quality and safety of the project construction. The engineering practice shows that the technology is reliable, safe, effective, economic to similar foundation pit under compli- cated geological conditions for reference.
