Construction method suitable for lock catch steel pipe pile inner guide hole
The invention relates to the technical field of steel pipe piles, and particularly discloses a construction method suitable for locking an inner guide hole of a steel pipe pile, which comprises the following steps: S1, arranging a pipe pile, driving a guide frame, and primarily driving the steel pipe pile; s2, a driving assembly is used for driving a rotary excavating drill bit to conduct hole guiding on the interior of a drilled hole, a pipe pile is inserted firstly, then soil in the pipe pile is pumped out, the root is prevented from forming a loose area, and in order to guarantee that the rotary excavating drill bit can enter the phi 630 steel pipe pile for operation, and meanwhile it is considered that the geology of the cofferdam is mainly a sand layer, a clay layer and fully-weathered and strongly-weathered rock; two drill bits suitable for the inner diameter of a steel pipe are specially designed, the diameter of each drill bit is 55 cm, one drill bit is a closed drill bit used for guiding holes in a sandy soil layer and ensuring that sandy soil can be brought out of the water surface through river water scouring, and the other drill bit is an open drill bit used for guiding holes in a clay layer and ensuring that clay is smoothly poured out of the drill bits.
本发明涉及钢管桩技术领域，具体公开了一种适用于锁扣钢管桩内引孔的施工方法，包括以下步骤：S1，设置管桩，打设导向架，初打钢管桩；S2，使用驱动组件驱动旋挖钻头对钻孔内进行引孔，通过先插入管桩，再将管桩内的土质抽出，避免根部形成松动区，为保证旋挖钻钻头能进入Φ630钢管桩内作业，同时考虑围堰处地质主要为砂层、黏土层、全风化及强风化岩，特设计两种适合钢管内径的钻头，钻头直径55cm，一种为闭口钻头，用于砂质土层引孔，确保经过河水冲刷能将砂土带出水面，一种为开口钻头，用于黏土层引孔，确保顺利将黏土从钻头内倒出。
