Completely-weathered granite cast-in-place pile hole forming device and construction method
The invention discloses a fully-weathered granite cast-in-place pile hole forming device and a construction method. The cast-in-place pile hole forming device comprises a guide assembly, a drill bit assembly, a fixed rotating assembly, a propelling assembly and an outer protection assembly. A guide assembly of the hole forming device is connected with a fixed rotating assembly, a drill bit assembly is connected with a propelling assembly, and a clamping device and a locking device are arranged on the fixed rotating assembly. The propelling assembly is connected with the power arm, and the power arm provides propelling and rotating power for the whole hole forming device. The punching drill bits and the fracturing pipes of the hole forming device are annularly arranged at intervals along the center, when holes are formed in the cast-in-place pile, the holes are punched in a fully-weathered granite stratum and filled with the carbon dioxide fracturing pipes, and the punching process of hole filling of the fracturing pipes and the fracturing pipe mounting process are integrated through rotation switching; construction of cast-in-place pile hole forming on a harder stratum such as a fully-weathered granite stratum is rapidly achieved, meanwhile, the quality of cast-in-place pile hole forming is guaranteed through accurate drilling positioning blasting, and accurate blasting of the fully-weathered granite stratum is achieved.
本发明公开了一种全风化花岗岩灌注桩成孔装置及施工方法，该灌注桩成孔装置包括导向组件、钻头组件、固定旋转组件、推进组件以及外防护组件。成孔装置的导向组件与固定旋转组件连接，钻头组件与推进组件连接，位于固定旋转组件上设有夹紧装置和锁紧装置；推进组件与动力臂相连，动力臂为整个成孔装置提供推进和旋转动力。本发明成孔装置的打孔钻头和致裂管沿中心环形间隔布置，在对灌注桩成孔时，在全风化花岗岩地层打孔并装填二氧化碳致裂管，通过旋转切换将致裂管装填孔眼的打孔过程和致裂管安装过程一体化，快速实现在较坚硬地层如全风化花岗岩地层上的灌注桩成孔的施工，同时精确的钻孔定位爆破保证了灌注桩成孔的质量，实现了对全风化花岗岩地层的精准爆破。
