Description

Technical Field

[0001] The invention relates to the technical field of sediment treatment, in particular to a sediment treatment device for pile foundation mud wall protection. Background Art

[0002] When bored cast-in-place piles are used for the construction of pile foundation projects, if mud wall protection is adopted, after the hole is formed, the suspended particulate matter in the mud in the hole will settle at the bottom of the hole under the action of its own weight before the steel cage is placed. At this time, the bottom of the hole needs to be cleaned by a sediment treatment device.

[0003] To this end, a Chinese patent with publication number "CN116220036A" discloses a "Device for treating sediment from mud-walled drilling for building pile foundations and its use method." Its main structure includes a support tube, a partition fixedly connected to the lower portion of the inner wall of the support tube, a motor fixedly connected to the inner wall of the support tube, and a wall protection mechanism movably connected between the top of the partition and the inner wall of the support tube. This device for treating sediment from mud-walled drilling for building pile foundations and its use method comprises a wall protection mechanism, a slag removal mechanism, and a water spray mechanism. The motor rotates the dragon rod, and the arc-shaped guide plate rotates synchronously. At this time, the flat surface of the bottom of the arc-shaped guide plate removes the mud residue adhering to the bottom of the hole. The removed mud residue gradually rises to the position of the dragon rod along the arc surface of the arc-shaped guide plate during rotation. During the rotation of the dragon rod, the mud residue at the bottom of the hole is crushed and transported to the upper part of the dragon sleeve, where it is extracted by a slag extraction pipe, preventing sticky mud residue from adhering to the bottom of the hole and making it inconvenient to remove, thereby improving the removal quality.

[0004] However, in the actual cleaning process, after the water spray hole in the above-mentioned mud wall drilling sediment treatment device for building pile foundation is inserted into the borehole, the water flow impact generated is perpendicular to the circumferential inner wall of the borehole, while the sediment is located at the bottom of the borehole, and under the influence of gravity, the impact ability of the water flow on the sediment after the impact is relatively weak, which makes it difficult to blow the sediment to the vicinity of the dragon rod, seriously reducing the impact force of the water flow on the sediment. In addition, the rotation of the dragon rod causes the sediment to move upward, and it sucks and discharges the fixed sediment through the sediment suction pipe, causing the sewage and sediment to be absorbed together, so the degree of separation is relatively low. Summary of the Invention
