Directly sucking and reversely circular bottom slag-removing method and equipment before filling concrete for drilling cast-in-situ pile

Номер: CN0001332309A
Автор: NING JINSHENG, JINSHENG NING
Принадлежит:

The equipment of the present invention is composed of guide pipe, mud pump support frame, upper lifting bail of frame, cyclone desander, discharge pipe, return pulp pipe etc. The mud containing a lotof sand drew out by using mud pump or sewage pump from bottom of hole of filling pile is sent through the guide pipe to desander that separates the pulp and sand. Then, the sand is circulated out from spigot opening and the pulp is returned to bottom of hole of filling pile through return pulp pipe. The pump and the guide pipe can be vibrated to make hypostases going up, in order to draw out it easily during the process of slag removal. The invention provides the features of simple, easy to operation, fast speed to remove slag, high efficiency and lower cost. It can also be used to deal with the accident that the drilling head is buried in the borehole.
