Rapid pile splicing method for cast-in-place piles under complex geological conditions
The invention relates to a rapid pile splicing method for cast-in-place piles under the complex geological condition. The method comprises the steps that the position, length and depth of an original pile are detected; the high-strength steel support is pressed down to the original pile multiple times at the original pile position; earthwork in the high-strength steel support is excavated to the pile head of the exposed original pile; the pile head of the original pile is broken through a water drill punching mode and a manual air pick mode until original pile steel bars are exposed; a cushion layer is poured around the pile head of the original pile; welding a reinforcement cage with the original pile reinforcing steel bars; concrete is poured into the reinforcement cage, and the high-strength steel support is pulled while the concrete is poured; and the high-strength steel support can be repeatedly used for pile splicing work of a next pile. The method has the advantages of being high in excavation speed, good in rigidity, free of secondary formwork erecting, capable of being repeatedly used and the like, can be carried out under the complex geological condition, and has good practicability and generalization performance.
本公开涉及一种在复杂地质情况下灌注桩快速接桩方法，方法包括探测原桩的位置、长度与深度；在原桩位置分多次下压高强度钢制支护至原桩处；将所述高强度钢制支护内的土方挖掘至裸漏原桩桩头；通过水钻打孔和人工风镐的方式破除所述原桩桩头直至裸漏出原桩钢筋；在原桩桩头周边浇筑垫层；将钢筋笼与所述原桩钢筋焊接；将混凝土浇筑至所述钢筋笼内，边浇筑混凝土边上拔所述高强度钢制支护；并且所述高强度钢制支护可重复利用进行下一根桩的接桩工作。本发明具有开挖速度快、刚度好、无需二次支模且可重复利用等优点且能够在复杂地质情况下进行，具有较佳的实用性和推广性。
