Construction method of novel cast-in-place concrete stiff composite pile
The invention relates to the technical field of building construction, in particular to a construction method of a novel cast-in-place concrete stiff composite pile. The pouring method comprises a preparation stage, wherein one end of a flexible pipeline is fixed to a drill bit, and the other end of the flexible pipeline penetrates into a steel pipe from the bottom end of the steel pipe to a feeding hopper to be fixed; a grouting pipe penetrates from the top end of the flexible pipeline and is rotated in the forward direction, and the grouting pipe is connected with the drill bit through a threaded connector; the slewing mechanism is started to rotate forwards, and the steel pipe and the drill bit are driven to rotate synchronously; the lifting mechanism is started to drive the slewing mechanism, the steel pipe and the drill bit to synchronously ascend and descend; grouting is conducted in the grouting pipe, and grout is sprayed out through the grout spraying opening and evenly stirred with the soil layer till drilling is conducted to the preset depth; a concrete cast-in-place pile is constructed, specifically, concrete is poured into the flexible pipeline; after the concrete is filled, the slewing mechanism rotates reversely, and the drill is separated from the steel pipe; and the grouting pipe is reversed, the grouting pipe is separated from the drill bit, and the grouting pipe is pulled out.
本发明涉及建筑施工技术领域，具体涉及一种新型现浇混凝土劲性复合桩的施工方法。浇筑方法包括准备阶段：将柔性管道的一端固定在钻头上，另一端从钢管的底端穿入钢管至投料斗处固定；注浆管从柔性管道的顶端穿入并正向转动注浆管，通过螺纹接头将注浆管与钻头连接；正向转动钢管，将钢管和钻头锁紧：启动回转机构正转，驱动钢管和钻头同步转动；水泥土搅拌桩施工：启动升降机构驱动回转机构、钢管和钻头同步升降；往注浆管内注浆，浆液经喷浆口喷出，与土层搅拌均匀，直至钻进至预设深度；混凝土现浇桩施工：向柔性管道内浇筑混凝土；混凝土灌满后回转机构反转，钻头与钢管脱离，拔出钢管；将注浆管反转，注浆管与钻头脱离，拔出注浆管。
