Problems solved by technology
[0002] At present, bored cast-in-situ piles are widely used in engineering; bored cast-in-place piles have many advantages and disadvantages, the biggest disadvantage is that dredging is not complete; the existing technology is to use water flushing to dredge, that is, to wash with high-pressure water The well hole will make the sediment turn up, and the sediment will be taken out with the water flow and mud flow; because the density of the sediment is higher than that of water and wall mud, it is impossible to completely remove it, and the sediment that has not been removed will settle at the bottom of the pile, seriously Affects the bearing capacity of the shape and affects the quality of the building

The invention provides a cast-in-situ bored pile sediment device. The cast-in-situ bored pile sediment device comprises a slag removing hole vertically formed in the ground, a slag removing barrel, a spiral slag removing piece and a plurality of one-way rods, wherein the upper end and the lower end of the slag removing barrel are both in a through shape, and the slag removing barrel is vertically and movably arranged in the slag removing hole; the spiral slag removing piece is rotationally arranged in the slag removing barrel; the tops of the one-way rods are hinged to the lower surface of the spiral slag removing piece, and the bottoms of the one-way rods obliquely abut against the upper surface of the spiral slag removing piece; and the projections of the tops of the multiple one-way rods in the vertical direction are located on the same straight line, and the length of the one-way rods is larger than the screw pitch of the spiral slag removing piece. The cast-in-situ bored pile sediment device can well remove sediment.
Description
technical field [0001] The invention belongs to the technical field of construction and relates to a sedimentation device for bored piles. Background technique [0002] At present, bored cast-in-situ piles are widely used in engineering; bored cast-in-place piles have many advantages and disadvantages, the biggest disadvantage is that dredging is not complete; the existing technology is to use water flushing to dredge, that is, to wash with high-pressure water The well hole will make the sediment turn up, and the sediment will be taken out with the water flow and mud flow; because the density of the sediment is higher than that of water and wall mud, it is impossible to completely remove it, and the sediment that has not been removed will settle at the bottom of the pile, seriously Affect the bearing capacity of the shape and affect the quality of the building. Contents of the invention [0003] The object of the present invention is to provide a bored pile sedimentation ...
