大口径水井施工及基桩钻孔工程实践证明，基桩钻孔使用的旋转类钻机，可以应用于松散含水层大口径水井施工，反循环钻进是旋转钻机在松散含水层中大口径水井理想的施工方式。
The practice of large-diameter well construction and pile foundation drilling has proved that the rotary drilling rig used for foundation pile drilling can be applied to the construction of large-diameter wells in loose aquifers. Reverse circulation drilling is ideal for large-diameter wells in loose aquifers by reverse drilling Construction methods.
