Prefabricated pipe pile permanent support grouting construction method and device
The invention discloses a prefabricated tubular pile permanent support grouting construction method and device, and relates to the technical field of grouting construction.The method comprises the steps that a prefabricated tubular pile is hoisted to a preset position, and grouting pipes are arranged according to grouting requirements; the pile tip is welded to the prefabricated pipe pile and the fixing piece; grouting pipes are installed in a segmented mode and welded to the fixing pieces, and meanwhile concrete plugs are plugged into the pipe holes; the installed grouting pipe and the prefabricated pipe pile are pressed to the pile position of the guide hole section by section, the grouting pipe is installed section by section, and the prefabricated pipe pile is pressed to the construction elevation section by section; and grouting is conducted on the grouting pipe, the concrete plug is pushed out through pressure, and grouting construction is completed. The device comprises a prefabricated pipe pile, a fixing piece, a grouting pipe and a pile tip. A fixing piece is arranged on the outer surface of the prefabricated pipe pile and is welded with the grouting pipe; the pile tip is installed at the lower end of the prefabricated pipe pile and welded to the fixing piece. According to the construction method, the grouting pipe and the prefabricated pipe pile sink together by expanding the guide hole in the pile tip, so that the drilling grouting construction is reduced, and the prefabricated pipe pile is protected.
本发明公开了一种预制管桩永久支护注浆施工方法及装置，涉及注浆施工技术领域，方法包括将预制管桩吊装至预设位置，按注浆要求布置注浆管；将桩尖与预制管桩、固定件焊接；分节安装注浆管，并与固定件焊接，同时将混凝土塞塞至管孔内；将安装完成的注浆管与预制管桩分节压制到引孔的桩位，分段安装注浆管，分段压制预制管桩至施工高程；对注浆管注浆，通过压力将混凝土塞逼出，完成注浆施工。装置包括预制管桩、固定件、注浆管以及桩尖；预制管桩外表面上设有固定件，固定件与注浆管焊接；桩尖安装在预制管桩下端，且桩尖与固定件焊接。本发明通过桩尖扩大引孔，将注浆管与预制管桩一同下沉，减少了转孔注浆施工，保护了预制管桩。
