Cast-in-place pile and steel pipe pile combined foundation construction method suitable for underwater temporary pier
The invention discloses a cast-in-place pile and steel pipe pile combined foundation construction method suitable for an underwater temporary pier, and particularly relates to the field of underwater temporary pile foundation construction work.The method comprises the following steps that an overwater steel platform is erected, after drilling is conducted through an impact drill bit, a prefabricated steel reinforcement cage with the diameter slightly larger than that of a steel pipe pile is hoisted, and the steel reinforcement cage is constructed; then welding work of a steel reinforcement cage and steel pipe pile combined component is conducted on the top of the steel casing through a crane, the combined component is lowered to a set elevation, underwater concrete is poured, finally, the steel pipe piles are lengthened, a cast-in-place pile and steel pipe pile combined foundation is formed, and the concrete, the steel reinforcement cage and the steel pipe piles serve as a bearing structure jointly. The combined structure is adopted, the problem that the bearing capacity is insufficient due to the fact that a pure steel pipe pile structure cannot be directly driven into a rock stratum is solved, and the problems that a pure concrete structure is difficult to break and influences river navigation are solved.
本发明公开了一种适用于水中临时墩的灌注桩与钢管桩组合基础施工方法，具体涉及水中临时桩基础施工作业领域，其包括以下步骤：搭设水上钢平台，通过冲击钻头进行钻孔后，吊放预制完成的直径略大于钢管桩的钢筋笼，接着在钢护筒顶部通过吊机进行钢筋笼和钢管桩组合构件的焊接工作，将组合构件下放至制定标高，并灌注水下混凝土，最后对钢管桩进行接长，形成灌注桩和钢管桩组合式基础，混凝土、钢筋笼和钢管桩共同作为承载结构，本发明采用组合型的结构，不但克服了纯钢管桩结构无法直接打入岩层，导致承载力不足的难题，而且解决了纯混凝土结构难以破除，影响河道通航的问题。
