Cast-in-place pile construction device and method combined with spiral drilling suction
The invention relates to a cast-in-place pile construction device and method combined with spiral drilling suction, the cast-in-place pile construction device comprises a hollow drill bit, the hollow drill bit is provided with a suction channel, the suction channel is connected with a transportation pipeline, and the suction channel is in running fit with the transportation pipeline; an air injection hole is formed in the front end of the hollow drill bit; a pulse air pressure device provides a pulse type air source for the air injection hole; the hollow drill bit is driven by a rotary driving device to rotate, the conveying pipeline and the hollow drill bit are driven by a lifting driving device to move up and down, and the top of the conveying pipeline communicates with a suction device or a grouting device. When the hollow drill bit drills holes, the pulse air pressure device and the suction device work at the same time to improve the drilling efficiency, after drilling is finished, the hollow drill bit is matched with the grouting device to conduct grouting, the two construction steps are reasonably linked, on one hand, the cast-in-place pile manufacturing efficiency is improved, on the other hand, hole well deformation can be prevented, and the construction efficiency is improved. And the pouring quality is ensured.
一种结合螺旋钻孔抽吸的灌注桩施工装置及方法，包括空心钻头，空心钻头设有抽吸通道，抽吸通道与运输管道连接，且抽吸通道与运输管道转动配合；空心钻头前端设有喷气孔，喷气孔由脉冲气压装置提供脉冲式气源；空心钻头由旋转驱动装置带动旋转，运输管道和空心钻头通过升降驱动装置驱动上下移动，运输管道顶部连通抽吸装置或注浆装置。本发明的空心钻头在钻孔的同时，脉冲气压装置和抽吸装置同时工作，用于提高钻孔效率，钻孔结束后，空心钻头配合注浆装置进行注浆，两个施工步骤进行了合理化的衔接，一方面提高了灌注桩制作效率，另一方面也可以防止孔井变形，保证了灌注质量。
