Abstract
The invention discloses a tube pile provided with a posttensioned prestressing steel noose and a posttensioned prestressing pulling tube pile, comprising a tube pile body and a bearing platform board at the upper end of the pile body, a hole is arranged at a circle of coaxial line in the pile body, the lower end of the posttensioned prestressing steel noose is provided with the expanded head, the upper end penetrates through the hole arranged on the pile body, is tensioned and is connected and fixed by virtue of a connecting piece, and the upper end of the steel noose and the connecting piece thereof are arranged in the bearing platform board. By adopting the invention, application range of the tube pile is expanded, posttensioned prestressing is adopted, rigidity of the pile body is greatly improved, the pile body is extruded under the prestressing longitudinal action and is radially enlarged, soil body is extruded, and uplift resistance is improved, thus pile length can be shortened; and meanwhile cracking phenomenon as the pile body is tensioned is overcome.
Description
Technical field
The present invention relates to building field, be specifically related to pile tube.
Background technology
The pre-tensioned prestressing reinforced concrete pipe pile is widely used in the engineering constructions such as house, road, bridge with its superior performance.It mainly acts on is to be squeezed on the harder rock stratum, the end, ground by machinery to nail is the same, can better support the weight of buildings such as house, bridge.And pile tube can not use as uplift pile, and this has received limitation with regard to the application that makes pile tube.The intensity of post-tensioned prestressing steel strand cable then is 7-8 times of plain bars, substitutes the reinforcing bar of original pretensioning as adopting the steel strand cable, will practice thrift steel using amount.Also do not see at present the resistance to plucking pile tube of this structure.
Summary of the invention
The technical problem that the present invention will solve provides a kind of pile tube and post-tensioned prestressing resistance to plucking pile tube that is provided with post-tensioned prestressing steel strand cable hole, improves the resistance to plucking supporting capacity of pile tube, simultaneously, practices thrift the steel using amount of pile foundation.
The present invention realizes through following technical scheme:
A kind of pile tube that is provided with post-tensioned prestressing steel strand cable hole comprises the pile tube pile body, and all coaxial lines are provided with the hole in the said pile body.
Each Kong Xinyu pile body center of circle in said hole is equidistant, and said hole five equilibrium is arranged at a week in the pile body.
A kind of post-tensioned prestressing resistance to plucking pile tube; Comprise the pile tube pile body; The cushion cap face of pile body upper end, all coaxial lines are provided with the hole in the said pile body, and post-tensioned prestressing steel strand cable lower end is provided with enlarged footing; The upper end is fixed through the connector connection after passing the set hole of pile body, stretch-draw, and said steel strand cable upper end and connector thereof are positioned at the cushion cap face.
The further improvement project of the present invention is, each Kong Xinyu pile body center of circle in said hole is equidistant, and said hole five equilibrium is arranged at a week in the pile body.
The present invention further improvement project is that said enlarged footing is nut or extruding anchor or concrete precast element.Said connector is an anchor clamp.
The present invention compared with prior art has following obvious advantage:
Expand the pile tube range of application, made pile tube be used for uplift pile; Adopt post-tensioned prestressing to improve pile body rigidity greatly, under effect, pile body is squeezed at pre-stressed longitudinal, radially enlarges, and the soil body is squeezed, and increases uplift resistance, and it is long to shorten stake like this; Overcome pile body owing to drawn the cracking phenomena of generation.
Description of drawings
Fig. 1 is a cross-sectional schematic of the present invention.
Fig. 2 is Figure 1A-A cross-sectional schematic.
The specific embodiment
Like Fig. 1, shown in 2, a kind of pile tube that is provided with post-tensioned prestressing steel strand cable hole comprises pile tube pile body 1, and all coaxial lines are provided with hole 3 in the said pile body 1.Each Kong Xinyu pile body center of circle in said hole 3 is equidistant, and said hole 3 five equilibriums are arranged at a week in the pile body 1.
Like Fig. 1, shown in 2, the present invention includes pile tube pile body 1, the cushion cap face 2 that pile body 1 upper end is provided with.All coaxial lines are provided with hole 3 in pile body 1, and post-tensioned prestressing steel strand cable 4 lower ends are provided with enlarged footing 5, and the upper end connects fixing through connector 6 after passing the set hole 3 of pile body 1, stretch-draw.Steel strand cable 4 upper ends and the connector 6 that is provided with on it are embedded in the cushion cap face 2.
As shown in Figure 2, each Kong Xinyu pile body 1 center of circle in said hole 3 is equidistant, and said hole 3 five equilibriums are arranged at a week in the pile body 1.
In the present embodiment, connector 6 is selected anchor clamp for use, and enlarged footing 5 is selected the extruding anchor for use.
The present invention prepares process: when prefabricated tubular pile, reserve steel strand cable hole.During use, the steel strand cable is passed hole set on the pile body 3 (aperture, aperture Daewoo top in stomidium 3 exits under the pile body is with the enlarged footing coupling) from bottom to top; Drive piles by conventional method then, behind the arrival desired location, the cast-in-place cushion cap face in the upper end of pile tube; After the cushion cap face reaches setting intensity, said steel strand cable is carried out stretch-draw, fix with anchor clamp after the stretch-draw; And then with concrete the stretch-draw hole on the cushion cap face is tamped, steel strand cable and connector are embedded in the cushion cap face.
