Abstract
The utility model relates to the technical field of building construction equipment and discloses a spiral line concrete pipe pile device. The spiral line concrete pipe pile device comprises a pipe pile body; the pipe pile body is provided with a pile body; a grouting pipe is arranged in the middle of a pipe pile; the grouting pipe shares the same axis with the pile body; and the surface of the pipe pile body is provided with spiral grooves. According to the spiral line concrete pipe pile device, a spiral line is used as a dissipation channel of pore water, the ground swell is reduced, and the bearing capacity of the pile can be improved.
Description
Technical field
The utility model relates to the technical field of construction implement device.
Background technology
Chinese invention patent number: 200910193702.5 disclose a kind of concrete tubular pile; Said pile tube comprises pile body and following pile body; The said pile body of going up is an integral structure with following pile body; The cross section of last pile body is greater than the cross section of following pile body, and the cross section of last pile body is annular or hollow square, and the cross section of following pile body is an annular.The said length L that goes up pile body is 1/3 to 1/2 of said pile tube total length H; Said going up is the transition slope between pile body and the following pile body, the angle beta on said transition slope is 30 ° to 60 °.Chinese invention patent number: 200710143380.4 disclose the special-purpose bar shape tubular pile mould of a kind of building foundation engineering; It comprises core rod, upper die and lower die; Upper die and lower die are enclosed within on the core rod; Have the trapezoidal concave bar groove of ring-type in the upper die and lower die die cavity at interval; Domatic and template face included angle A are 10～60 degree before the trapezoidal concave bar groove of ring-type in the trapezoidal concave bar groove of ring-type, the back is domatic and template face included angle B is 60～10 degree, vertically are provided with one or 2 or many concave bar grooves between the trapezoidal concave bar groove of ring-type spaced apart and communicate with the trapezoidal concave bar groove of ring-type.
Traditional pile tube is linear pattern, because the pile body cross section does not have any variation, therefore soil compaction effect is obvious in the piling process, and native mesopore water can't dissipate, and often causes earth heaving, common quality defects such as adjacent studs come-up.
The utility model content
The utility model purpose aims to provide a kind of helix concrete tubular pile device, and this helix concrete tubular pile device utilizes helix as the passage that pore water dissipates, and reduces earth heaving, can improve the bearing capacity of stake.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of helix concrete tubular pile device; Comprise the pile tube body, said pile tube body is provided with pile body, is provided with grout pipe in the middle of the said pile tube; Said grout pipe and pile body are same axles, and the surface of said pile tube body is provided with helicla flute.
It is 30 millimeters-50 millimeters that said a kind of helix concrete tubular pile device, the surface of its pile tube body are provided with the spiral fluted groove depth.
Said a kind of helix concrete tubular pile device, it is 40 millimeters that the surface of its pile tube body is provided with the spiral fluted groove depth.
This helix concrete tubular pile device utilizes helix as the passage that pore water dissipates, and reduces earth heaving, can improve the bearing capacity of stake.This helix concrete tubular pile device is applicable to all pile tubes, is specially adapted to the high figure layer of groundwater table.This helix concrete tubular pile device can improve the bearing capacity of stake, eliminates pore water pressure.This helix concrete tubular pile device utilizes helix as the passage that pore water dissipates, and reduces earth heaving.This helix concrete tubular pile device is employed in the technology that the pile tube surface increases helix, and a side skin friction is increased, and the supporting capacity of stake improves, and pore water dissipates has passage.
