Construction method of prefabricated pile body of carrier pile
The invention discloses a construction method of a prefabricated pile body of a carrier pile, and belongs to the technical field of composite foundation construction. The construction method comprises the following steps that S1, the prefabricated pile body of the carrier pile is put into a pile hole till the bottom end of conical steel of the prefabricated pile body makes contact with the surface of a carrier; S2, the prefabricated pile body is subjected to static pressing through a static pile press machine till the prefabricated pile body is pressed into the carrier by 0.2-0.3m; S3, cement slurry is poured into the pile hole till the pile hole is full of the cement slurry, and connection between the prefabricated pile body and the carrier is reinforced after the cement slurry is solidified and formed; and S4, the carrier pile is loaded. The conical steel is arranged at the bottom end of the prefabricated pile body, the conical steel and part of the prefabricated pile body are pressed into the carrier in a mode of performing static pressing on the prefabricated pile body, and then construction of the prefabricated pile body is achieved in a mode of cement slurry pouring. According to the construction method, the connection strength between the prefabricated pile body and the carrier can be enhanced, and the problem that an existing prefabricated pile body and the carrier are prone to being separated is solved.
本发明公开了一种载体桩预制桩身的施工方法，属于复合地基施工技术领域，包括以下步骤：S1：将载体桩的预制桩身下放进桩孔内，直至预制桩身的锥形钢底端接触载体表面停止；S2：通过静压桩机静压预制桩身，直至预制桩身压入载体内0.2‑0.3米停止；S3：将水泥浆料灌注进桩孔内，直至水泥浆料灌满桩孔停止，等待水泥浆料凝固成型，加固预制桩身与载体间的连接；S4：加载载体桩；本发明在预制桩身的底端设置锥形钢，通过静压预制桩身的方式将锥形钢以及部分预制桩身压入载体内，再通过灌注水泥浆的方式实现预制桩身的施工，这种施工方法能够增强预制桩身与载体间的连接强度，解决现有预制桩身与载体间容易产生脱离的问题。
