Furthermore, the two ends of the transverse pipe of the T-shaped communicating pipe are large and the middle is small.

Furthermore, the T-shaped communicating pipe is fixedly connected with a slag sucking port of the slag sucking disc, a lifting ring is arranged at the upper end of the transverse pipe of the T-shaped communicating pipe, and the lifting ring is connected with a steel wire rope penetrating through the top end of the cylinder.

Further, the top cover of the cylinder body is of a dense-hole net structure.

Furthermore, the bottom end of the side wall of the cylinder body is provided with a tooth-shaped end part forming a slag discharge port.

Furthermore, the bottom of the inner wall of the cylinder body is provided with clamping blocks which are oppositely arranged.

Further, the slag suction disc is an inverted funnel-shaped disc.

Has the advantages that: the slag extractor for cleaning underground piles and walls sucks the sediments in the holes into the barrel body through the Venturi effect generated by the high-speed fluid flowing into the T-shaped communicating pipe, and then the barrel body is lifted out of the underground piles and the walls to remove the slags. On one hand, the sediment is only sucked into the cylinder body, the lifting height is small, and the needed slag discharging power is small; on the other hand, the circulation of the slurry is in the hole, so that the stability of the height of the liquid level can be effectively ensured, the disturbance of the slurry in the hole can be reduced, and the hole collapse can be effectively prevented.
