Construction method of secant pile with independent pilot tunnel
The embodiment of the invention provides a construction method of a secant pile with an independent pilot tunnel. Retaining wall piles comprise plain piles and reinforced concrete piles which are alternately arranged, the secant pile is formed by mutually meshing the adjacent retaining wall piles, and the formed secant pile is used for a retaining wall of an underground excavation pit foundation. The method comprises the steps that the pilot tunnel facilitating construction of the retaining wall piles is excavated before construction of all the retaining wall piles according to the construction sequence of the retaining wall piles; the plain piles are constructed according to the construction sequence of jumping three and driving one; and the position of the reinforced concrete pile is located between every two adjacent plain piles, the section of each reinforced concrete pile is in lap joint with the sections of the two corresponding adjacent plain piles, and the mutually-meshed secant pile is formed. The pilot tunnel facilitating construction of the retaining wall piles is excavated before construction of all the retaining wall piles, and the cost is reduced.
本发明实施例提供一种具有独立导洞的咬合桩施工方法，护壁桩包括交替设置的素桩和荤桩，通过相邻的护壁桩互相咬合形成咬合桩，将所形成的咬合桩用于暗挖坑基护壁，所述方法包括：按照护壁桩施工顺序在各护壁桩施工前开挖便于护壁桩施工的导洞；素桩按照跳三打一的施工顺序进行施工；每相邻的两个素桩之间为荤桩位，每个荤桩的截面与相邻的两个素桩截面分别搭接，形成互相咬合的咬合桩。通过在各护壁桩施工前开挖便于护壁桩施工的导洞，降低成本。
