Drilled hole cleaning device for cast-in-place pile construction

Abstract

The invention discloses a drilled hole cleaning device for cast-in-place pile construction and relates to the technical field of hole cleaning devices. The device comprises a vertical rod and a hole,a mounting plate is fixedly arranged at the bottom of the vertical rod, a plurality of soil slag crushing mechanisms are arranged on the bottom surface of the mounting plate at equal intervals, a soilabsorption mechanisms is arranged between every two adjacent soil slag crushing mechanisms, the soil absorption mechanisms are arranged in the mounting plate, a drying mechanism is fixedly arranged between every two adjacent soil slag crushing mechanisms, and the soil slag crushing mechanisms comprise stirring shafts, stirring fragments are annularly arranged on the peripheral side of the stirring shafts, the stirring fragments are flush with the bottom surface of the stirring shafts, each soil absorption mechanism comprises a soil absorber, the soil absorbers are mounted on the top surface of the mounting plate, the soil absorbers are connected with suction pipes, the suction pipes penetrate through through holes, the through holes are formed in the mounting plate, and suction discs aremounted at the bottoms of the suction pipes. The problems that in the existing cleaning process of the sediment at the hole bottom of the cast-in-place pile, only small or light sediment can be cleaned, the sediment with larger particle size at the hole bottom and thick sediment are inconvenient to clean, the hole cleaning time is long, and hole cleaning is incomplete are solved

Description

technical field [0001] The invention belongs to the technical field of hole cleaning devices, and in particular relates to a hole cleaning device after drilling for construction of 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. Commonly used ones are: (1) Bored 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 no soil squeezing during construction, but the settlement of the piles is slightly larger. (2) Immersed tube cast-in-situ pile: sink the steel pipe with reinforced concrete pile shoe (pile tip) or valve-type pile shoe into the soil by hammering or vibration, and then pour concrete and pull out the pipe at the same time to form a pile. Due to the advantages of no vibration, no soil extrusion, low noise, and suitable for use in densely built urban a...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, in the process of cleaning the sediment at the bottom of the cast-in-situ pile, only small or lighter sediment can be cleaned, and it is inconvenient to clean the larger sediment at the bottom of the hole, and there is a phenomenon that the cleaning time is long and the hole is not cleaned completely. Engineering quality is difficult to guarantee
