Stirring pile construction device and construction method
The invention provides a stirring pile construction device and a construction method, relates to the technical field of stirring pile construction, and aims to solve the problem that horizontal stirring pile construction reinforcement is difficult to carry out on a settlement stratum below an existing overground structure at present, an arc-shaped guide pipe is adopted to establish a bent guide channel from the ground to the underground, and an elastic pipe penetrates through the guide channel to gradually adjust the orientation; the stirring drill bit can operate in the horizontal direction to form a grouting hole channel, the process of constructing the underground horizontal stirring pile from the ground is achieved in combination with an internal material pipe set, construction of the stirring pile below an existing overground structure is met, the construction difficulty is lowered, surrounding influences are reduced, and the problem of continuous sedimentation is solved.
本发明提供一种搅拌桩施工装置及施工方法，涉及搅拌桩施工技术领域，针对目前既有地上结构下方沉降地层难以进行水平搅拌桩施工加固的问题，采用弧形导向管建立从地面到地下的弯曲导向通道，弹性管穿过导向通道逐渐调整朝向，使得搅拌钻头能够在水平方向运行形成注浆孔道，结合内部物料管组实现从地面施工地下水平搅拌桩的过程，满足既有地上结构下方搅拌桩的施工，降低施工难度，减少周围影响，解决持续沉降问题。
