Construction method of prefabricated end-bearing pipe pile
The invention mainly relates to the field of engineering, in particular to a construction method of a prefabricated end-bearing pipe pile. The construction method of the prefabricated end-bearing pipe pile mainly solves the problem that the construction quality is difficult to guarantee when a traditional cast-in-place pile is used as a cast-in-place pile, and mainly comprises the following four steps that step 1, hole forming is conducted, a hole is formed to a bearing soil layer by adopting a traditional cast-in-place pile hole forming construction method; step 2, pile sinking is conducted, specifically, before pile sinking, a hollow core of a prefabricated pile is sealed through an end steel cap at the end of the prefabricated pile, and then the prefabricated pile sinks into a designed elevation position according to a designed length and is hung up; step 3, concrete is poured, a grouting pipe is placed in the middle of the pipe pile, and then grouting is conducted; and step 4, remaining gaps in the pile hole are filled. According to the construction method of the prefabricated end-bearing pipe pile, the main stress structure of the structure is a prefabricated part, the construction quality can be well guaranteed, and pile supplementing is avoided.
本发明主要涉及工程领域，是一种预制端承管桩的施工方法，主要解决传统灌注桩作为灌注桩时施工质量难以保障的问题，本施工方法主要分为四个步骤，第一步成孔，采用传统的灌注桩成孔的施工方法成孔至持力土层；第二步沉桩，沉桩前，预制桩端头采用端头钢帽封住预制桩空芯，然后将预制桩按照设计长度沉入设计标高位置并挂起；第三步灌注混凝土，将注浆管从管桩中间放入，然后注浆；第四步填筑桩孔内剩余空隙。这种结构的主要受力结构为预制构件，施工质量可以得到很好的保证，避免补桩。
