超大规模深基坑钻孔咬合桩施工工艺研究

Research on Construction Technology of Large Scale Deep Foundation Excavation Drilling Secant Pile Wall

通过研究深基坑钻孔咬合桩的施工工艺,改变单一机械施工咬合桩的传统做法,在保证成桩质量的前提下,可以提高施工效率降低工程造价。结合工程实例,验证了该工艺的可实施性和推广价值,为超大规模深基坑咬合桩的施工提供参考经验,具有较好的推广应用价值。

Through the research of deep foundation excavation drilling secant piles wall construction technology, the single mechanical construction secant piles wall of tradition is changed. On the premise of guaranteeing the quality of pile, it can improve the efficiency of construction to reduce the project cost. Combined with the engineering example, the feasibility and popularization value of this Drocess are verified, and the reference experience is provided for the construction of the secant pile wall in the large scale deep foundation excavation, which has better application value.
