Preferably, the submersible pump is provided in two.
Preferably, 16 evenly distributed slurry outlets are arranged on the transverse conduit.
The invention also discloses a hole cleaning method based on the secondary hole cleaning device for the bored pile, which comprises the following steps of:
s1, after the steel reinforcement cage is installed, putting the submersible pump into the drilled pile, and lengthening the upper end of the submersible pump by a first vertical guide pipe;
s2, when the first vertical guide pipe penetrates through a covering layer of the drilled pile and enters a rock stratum, the power supply is switched on, and the submersible pump starts to work;
s3, pumping the slurry in the drilled pile into a submersible pump, pressurizing the slurry, uniformly ejecting the slurry through slurry outlet holes arranged on a transverse guide pipe, and cleaning the drilling slag between the reinforcement cage and the hole wall and at the hole bottom;
and S4, pumping the slurry carrying the drilling slag out of the drilled pile through the second vertical conduit under the action of the submersible pump until the sediment at the bottom of the hole meets the specification requirement.
Compared with the prior art, the invention has the beneficial effects that: the drilling slag cleaning device can clean the drilling slag between the reinforcement cage and the hole wall, improves the quality of secondary hole cleaning, and improves the hole cleaning efficiency because the plurality of submersible pumps can clean holes in a water jetting mode at the same time.
