Problems solved by technology
However, it is difficult to completely remove the sediment by concrete impact, and the slurry change process requires certain auxiliary settings and construction procedures to ensure that it is time-consuming
In addition, after the drilling machine completes the drilling operation, the attachment can be replaced to complete the sediment removal, but it takes time to replace the attachment and occupies the drilling machine, which affects the overall construction progress and production efficiency

The invention discloses a cast-in-place pile drilling sediment removing device. In order to overcome the defects in the prior art, the cast-in-place pile drilling sediment removing device is provided. The cast-in-place pile drilling sediment removing device comprises a rack, the rack is connected with a sediment removing mechanism through a vibration mechanism, the sediment removing mechanism comprises two grab buckets symmetrically arranged on the rack, the grab buckets are installed on the rack in a hinged mode through swing arms, and the vibration mechanism is in transmission connection to the swing arms. The cast-in-place pile drilling sediment removing device consists of a mechanical device and a motor, does not generate transverse force except a rocker arm, does not generate transverse impact on a steel casing pressed in a drill hole, is easy to operate and maintain, works independently of a rotary drilling machine, does not occupy the working time of the rotary drilling machine, can work only by supplying power electricity to the outside, and is consistent with the bottom of the drill hole in shape, and the single sediment removal amount is relatively higher.
Description
technical field [0001] The invention relates to the field of infrastructure equipment, in particular to a borehole sediment removal device for cast-in-situ piles. Background technique [0002] Cast-in-place pile is a kind of pile made by forming holes in place and pouring concrete or reinforced concrete. The commonly used ones are: [0003] (1) Drilled cast-in-place piles: use auger drilling rigs, submersible drilling rigs, etc. to pour concrete into holes on the spot to form piles. There is no vibration and soil extrusion during construction, but the settlement of the piles is slightly larger. The auger drilling rig is suitable for cohesive soil, sandy soil and artificial filling soil above the groundwater level. The drilled soil block rises along the helical blade on the drill pipe and is discharged out of the hole. The hole diameter is about 300mm, and the drilling depth is 8-12m. Soil quality and water content to select drill pipe. The submersible drilling rig is suita...
