Summary of the invention
The deficiency existing for prior art, the purpose of this utility model is, a kind of prefabricated tubular pile with overhanging rod member of building for road and bridge is provided, this prefabricated tubular pile can reduce greatly the degree of difficulty of extruding overhanging rod member in the situation that ensureing smooth pile sinking, and make overhanging rod member can adapt to asymmetrical set-up mode, thereby the upper limit of rod member overhang is at least risen to the diameter of stake.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of prefabricated tubular pile with overhanging rod member of building for road and bridge, comprise the steel pipe that hollow pile lining and bottom are tapered, the tapered steel pipe in bottom is removably disposed in hollow pile lining, on the inwall of described hollow pile lining, be hinged with L-type wing bar, described L-type wing bar comprises extruded segment and puncture section, one end of extruded segment and the inwall of hollow pile lining are hinged, on the other end of extruded segment, be provided with puncture section, the end of puncture section is spininess, on the inwall of hollow pile lining, be provided with through hole with the corresponding position, puncture section end of type wing bar, puncture section is thrust in prefabricated tubular pile ground around through through hole.
The utility model also has following technical characterictic:
Described L-type wing bar symmetry is hinged on the inwall of hollow pile lining.
On the described asymmetric inwall that is hinged on hollow pile lining of L-type wing bar.
Described puncture section is circular-arc.
The utility model compared with prior art, has following technological merit:
Prefabricated tubular pile of the present utility model can increase greatly degree of roughness and the degree of irregularity of prefabricated tubular pile side in the situation that ensureing smooth pile sinking; Can reduce greatly the degree of difficulty of extruding overhanging rod member, and make overhanging rod member can adapt to asymmetrical set-up mode, thus by the upper limit of rod member overhang at least rise to stake diameter; Can effectively improve the vertical bearing capacity of prefabricated tubular pile and the resistance to capsizing of stake, improve the stability of prefabricated tubular pile and reduce pile body settlement.

Below in conjunction with drawings and Examples, particular content of the present utility model is described in more detail.
Detailed description of the invention
Below provide specific embodiment of the utility model, it should be noted that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, as shown in Figures 1 to 5, the present embodiment provides a kind of prefabricated tubular pile with overhanging rod member of building for road and bridge, comprise the steel pipe 2 that hollow pile lining 1 and bottom are tapered, the tapered steel pipe 2 in bottom is removably disposed in hollow pile lining 1, on the inwall of described hollow pile lining 1, be hinged with L-type wing bar 3, described L-type wing bar 3 comprises extruded segment 5 and puncture section 6, the inwall of one end of extruded segment 5 and hollow pile lining 1 is hinged, on the other end of extruded segment 5, be provided with puncture section 6, the end of puncture section 6 is spininess, on the inwall of hollow pile lining 1, be provided with through hole 4 with the puncture section 6 corresponding positions, end of L-type wing bar 3, puncture section 6 is thrust in prefabricated tubular pile ground around through through hole 4.
L-type wing bar 3 symmetries are hinged on the inwall of hollow pile lining 1.
On the asymmetric inwall that is hinged on hollow pile lining 1 of L-type wing bar 3.
The angle that when tapering of tapered steel pipe 2 bottoms, bottom does not stretch out hollow pile lining 1 with L-type wing bar 3, extruded segment 5 and hollow pile lining 1 form equates.So can more easily the puncture section 5 of L-type wing bar 3 be squeezed in prefabricated tubular pile ground around.
Use procedure of the present utility model is as described below:
One, the through hole on hollow pile lining 14 is carried out to necessary blocking, in case hollow pile lining 1 affects pile lining sinking because the Gravitative Loads of vibrations and L shaped wing bar 3 makes puncture section 6 pass in advance through hole sinking in ground process.It is to be noted: the through hole 4 blocking must be after pile sinking completes under pressure or impact force the section of being punctured 6 pass.
Two, utilize pile driver or other sinking apparatus and pile-sinking method that hollow pile lining 1 is sunk in ground.
Three, after hollow pile lining 1 installation, steel pipe tapered bottom 2 is inserted in hollow pile lining 1, is inserted in process and need on the tapered steel pipe 2 in bottom, applies necessary pressure or impact force.When in bottom, the tapered lower end of tapered steel pipe 2 contacts with extruded segment 5, the tapered lower end of the tapered steel pipe 2 in bottom will be exerted pressure or impact force to extruded segment 5, extruded segment 5 is rotated the pin joint around its end under the effect of pressure or impact force, thereby makes whole L shaped wing bar 3 that rotation occur.Due to puncture section 6 is curved and its arc radius be just in time the pin joint of extruded segment 5 ends to the distance of through hole 4, therefore in rotation process, puncture section 6 just will pass that through hole 4 thrusts in the foundation soil around hollow pile lining 1 and not with soil body generation dissection.After the tapered steel pipe 2 in its bottom is inserted in hollow pile lining 1 completely, extruded segment 5 will be vertical shape completely, and puncture section 6 has just been thrust in hollow pile lining 1 foundation soil around completely.
Four, after the tapered steel pipe 2 in bottom has been inserted in, steel pipe tapered bottom 2 and hollow pile lining 1 is fixed and is not taken out, to prevent L shaped wing bar 3 rotating backward in the prefabricated tubular pile course of work.
Five, in the space forming at the tapered steel pipe 2 of hollow pile lining 1 and bottom concrete perfusion for the gap around shutoff through hole 4 to meet requirement for anticorrosion.
