Description

The existing air-lift reverse circulation equipment cannot achieve the free movement of the slurry replacement conduit in the horizontal direction of the slot hole, and cannot perform hole cleaning, slurry replacement and slag discharge at different positions at the same depth layer of the slot hole, which is likely to lead to the problem of incomplete slurry replacement and slag discharge; (2). The existing air-lift reverse circulation equipment cannot achieve the vertical free movement of the slurry replacement conduit in the slot hole, and thus cannot efficiently perform hole cleaning and slurry replacement in different depth layers of the slot hole, affecting the slurry replacement efficiency. At the same time as incomplete slurry replacement and slag discharge, it is also likely to cause excessive scouring and long-term negative pressure at a certain depth layer, resulting in the serious consequence of slot wall collapse; (3). When the existing equipment uses the method of hoisting the slurry replacement pipe by a crane for hole cleaning, the equipment is numerous and messy, the operation is complicated, it is difficult to unified command, the coordination is difficult, the waste of human resources cost is large, and there are potential safety hazards such as easy damage to personnel and equipment, and excessive load at the slot hole affecting the stability of the slot hole.
