In Building Foundation Construction, How Does The Reverse Circulation Drill Rig Handle Different Types Of Foundation Soils? In building foundation construction scenarios, different types of foundation soils bring varying impacts to drilling operations, and the reverse circulation drill rig needs to make targeted adjustments to deal with these situations. When facing highly cohesive soil, the mud circulation system of the reverse circulation drill rig plays a role. It delivers mud with moderate viscosity to wrap soil particles around the borehole, reducing the adhesion of mud to the inner wall of the drill pipe and preventing borehole blockage caused by soil caking. At the same time, workers will properly control the drilling speed, giving the mud enough time to carry away crushed soil clods and maintaining smooth drilling. When encountering sandy soil, the anti-collapse measures of the reverse circulation drill rig are particularly critical. This type of soil has loose particles...
