Steel pipe pile rock-socketed construction technology under complex geological conditions
The invention provides a steel pipe pile rock-socketed construction process under complex geological conditions, which comprises the following steps: pre-formed hole construction: drilling holes to reach a plurality of pre-formed holes at design positions in complex geology through a drilling machine construction mode, and performing sand backfilling operation in the pre-formed holes; the number of the preformed holes is multiple, the preformed holes among the multiple preformed holes are arranged adjacently, and the lap joint distance between every two adjacent preformed holes ranges from 15 cm to 25 cm. Steel pipe pile sinking is conducted, specifically, the steel pipe pile is placed in the guiding device, pile sinking is conducted on the steel pipe pile in the preformed hole, and the pile sinking position and perpendicularity of the steel pipe pile are monitored according to the monitoring device; pouring of the steel pipe pile: after sand is taken out in the steel pipe pile, concrete pouring is carried out on the steel pipe pile by utilizing a guide pipe method; and the steel pipe pile is taken out, specifically, the steel pipe pile in the preformed hole is taken out, the preformed hole is filled with sand, and construction of the steel pipe pile is completed. According to the method, through the addition of the preformed holes and the like, pile sinking construction under the complex geological condition is achieved.
本发明提供了一种复杂地质条件下钢管桩嵌岩施工工艺，包括以下步骤：预成孔施工：通过钻机施工的方式，在复杂地质中，钻孔到达设计位置的若干的预成孔，并在预成孔内进行回填砂操作；所述预成孔为若干个，若干个预成孔之间的预成孔相邻设置，且相邻预成孔之间的搭接距离为15‑25cm；钢管桩沉桩：将钢管桩置于导向装置中，并对预成孔内的钢管桩进行沉桩，根据监测装置，监测钢管桩的沉桩位置和垂直度；钢管桩的浇筑：在钢管桩内，进行取砂后，利用导管法，对钢管桩进行混凝土浇筑；钢管桩的取出：取出预成孔内的钢管桩，对预成孔进行填砂，完成钢管桩的施工。本发明中，通过预成孔等的增加，实现了对于复杂地质条件下的沉桩施工。
