Sleeve type pile splicing structure and construction technology thereof
The invention relates to a sleeve type pile splicing structure and a construction technology thereof.The sleeve type pile splicing structure comprises a first prefabricated pipe pile extending to the position below the ground and a second prefabricated pipe pile located below the first prefabricated pipe pile, and the axis of the first prefabricated pipe pile and the axis of the second prefabricated pipe pile are parallel and extend in the height direction; the second prefabricated pipe pile extends upwards to be inserted into the inner ring of the first prefabricated pipe pile, and the inner ring of the first prefabricated pipe pile and the inner ring of the second prefabricated pipe pile are both filled with concrete. According to the construction technology, the pile foundation is constructed in a segmented mode, that is, the pile foundation is divided into the first prefabricated pile and the second prefabricated pile, the first prefabricated pile and the second prefabricated pile are constructed independently, and the construction difficulty is lowered; the problem that if piles with large bearing capacity are subjected to pile splicing through welding or after being subjected to pile splicing through a mechanical connection structure, due to the fact that the weight of a hammer is limited, the piles cannot be driven down when the piles cannot reach the elevation position required by design is solved.
本发明涉及一种套式接桩结构及其施工工艺，套式接桩结构包括延伸至地面下方的第一预制管桩，以及为位于第一预制管桩下方的第二预制管桩，第一预制管桩和第二预制管桩的轴线平行且沿高度方向延伸，第二预制管桩向上延伸插入第一预制管桩的内圈内，所述第一预制管桩的内圈和第二预制管桩的内圈均填充有混凝土。本发明施工工艺将桩基分段施工，即将桩基分为第一预制桩和第二预制桩，并且第一预制桩和第二预制桩单独施工，降低了施工难度；解决了承载力大的桩如果通过焊接接桩，或是机械连接结构接桩后再打桩，会存在由于锤重量有限，以至于桩打不到设计要求标高位置就打不下去的问题。
