Abstract

The utility model discloses a hole cleaning device for pile core of prestressed concrete pipe pile, which comprises a drill rod and a helical blade, wherein the helical blade is fixed with the drill rod by welding at equal intervals, the helical bit also comprises a cleaning plate for inner wall of the pile core of the pipe pile, the cleaning plate for inner wall of the pile core of the pipe pile is continuously distributed and fixed by welding along the outer edge of the helical blade, and the outer surface of the cleaning plate for inner wall of the pile core of the pipe pile is parallel to the axial direction of the drill rod; the outer surface of the cleaning plate on the inner wall of the tubular pile core is uniformly distributed with file cuts. The utility model has the advantages that: the utility model has the advantages that: helical blade takes earth out from drilling, and owing to set up the clean board of tubular pile stake core inner wall, consequently can extrude the cleanness to tubular pile stake core inner wall simultaneously, therefore easy operation improves the efficiency of construction.

Description

Hole cleaning device for pile core of prestressed concrete pipe pile

Technical Field

The utility model relates to a construction technical field, concretely relates to with clear hole device of tubular pile stake core.

Background

The prestressed concrete pipe pile has been more and more widely applied in engineering due to the advantages of high bearing capacity of a single pile, convenient construction and the like. However, a large amount of soil can be filled into the pile core in the pile driving, dormancy and excavation processes, the sundries such as soil, silt and the like in the hole after pile cutting are more, and a shovel is difficult to enter a deeper pile hole; the adoption of the Luoyang shovel easily causes sundries to sink and is difficult to draw out, so the whole operation process is complicated and the construction efficiency is low.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a when can clearing up the earth in the drilling consolidate device in arrangement to the hole inner wall. The specific technical scheme of the utility model is realized like this:

the utility model provides a clear hole device of prestressed concrete tubular pile stake core, includes drilling rod, helical blade equidistant and drilling rod welded fastening, auger bit still includes tubular pile stake core inner wall cleaning plate, tubular pile stake core inner wall cleaning plate is along helical blade outer border continuous distribution and welded fastening, the axial direction parallel of tubular pile stake core inner wall cleaning plate surface and drilling rod.

The outer surface of the cleaning plate on the inner wall of the tubular pile core is uniformly distributed with file cuts.

For the convenience of operation, the upper end of the drill rod is provided with threads, and the threads are connected with the handheld rotating handle.

In order to realize mechanized production, improve work efficiency and reduce labor intensity, the upper end part of the drill rod is connected with the output end of the motor through the reducer, and the motor and the reducer are arranged on the support which is arranged at the upper end of a drill hole.

The utility model has the advantages that: helical blade takes earth out from drilling, and owing to set up the clean board of tubular pile stake core inner wall, consequently can extrude the cleanness simultaneously to tubular pile stake core inner wall, simultaneously, prevents earth from the marginal whereabouts of blade, has improved clear hole efficiency, easy operation improves the efficiency of construction.

Detailed Description

The technical solution of the present invention will be described in detail with reference to the accompanying drawings.

The utility model discloses a drilling rod 1, helical blade 2 and tubular pile stake core inner wall cleaning plate 3, the tail end of drilling rod has connecting thread 101 to be connected with handheld turning handle, helical blade 2 equidistant and 1 welded fastening of drilling rod, tubular pile stake core inner wall cleaning plate 3 is connected along helical blade outer border 201 continuous distribution and adopt the welded mode, this tubular pile stake core inner wall cleaning plate surface 301 and drilling rod 1's axial direction parallel.

The working principle of the spiral drill bit is as follows:

for the convenience of operation, the upper end of the drill rod is provided with threads, and the threads are connected with the handheld rotating handle. The staff will the utility model discloses a device is connected with handheld turning handle, rotates handheld turning handle and can drive the device begins work. The helical blade enters the soil layer along with the rotation of the handheld rotating handle, soil is taken out along with the helical blade 2, and meanwhile, the outer surface 301 of the cleaning plate on the inner wall of the tubular pile core begins to extrude the soil attached to the hole wall, so that the hole wall becomes solid and smooth. In addition, the file 302 can be arranged on the outer surface 301 of the cleaning plate of the inner wall of the tubular pile core, after the helical blade enters the soil layer, the soil is taken out along with the helical blade 2 of the helical drill, and simultaneously, the outer surface 301 of the cleaning plate of the inner wall of the tubular pile core with the file begins to extrude and rub the attached soil and impurities on the inner hole wall, so that the inner hole wall becomes firmer and smoother. When the soil is cleaned, the rotation of the hand-held rotating handle is stopped, and the whole device is lifted out of the tubular pile core.
