From the compressive region of soil layer, arrangement of reinforcement along the circumferentially spaced glass fiber-reinforced polymer of support pile by constituting or being propped up by edge in the tensile region
The glass fiber-reinforced polymer of fender pile circumference alternate intervals arrangement is constituted with reinforcing bar；Arrangement of reinforcement is by circumferentially-spaced along support pile in the compressive region
The reinforcing bar of arrangement is constituted；The glass fiber-reinforced polymer, reinforcing bar be axially parallel to support pile axial direction.
Further, the lateral side regions between the tensile region and compressive region are the tectonic province of support pile, the tectonic province
Interior arrangement of reinforcement along the circumferentially spaced reinforcing bar of support pile by constituting.
Further, arrangement of reinforcement quantity is more than arrangement of reinforcement quantity in compressive region in the tensile region.
Further, arrangement of reinforcement is by circumferentially spaced along support pile in the support pile diameter 800mm, the tensile region
6 glass fiber-reinforced polymers are constituted, and arrangement of reinforcement along circumferentially spaced 4 reinforcing bars of support pile by constituting in the compressive region, the structure
Make in area that arrangement of reinforcement along circumferentially spaced 4 reinforcing bars of support pile by constituting, the glass fiber-reinforced polymer, the diameter of reinforcing bar are respectively
20mm。
Further, the support pile also include along support pile axially spaced-apart arrange some stirrups, the stirrup it is straight
Footpath is 10mm, and the spacing between the stirrup is 200mm.
The beneficial effects of the present invention are：
(1) support pile of the present invention with reinforcing bar mix matching somebody with somebody in tensile region using glass fiber-reinforced polymer or glass fiber-reinforced polymer
Muscle, the reinforcement manner of use causes the usage amount of reinforcing bar to be greatly decreased, saving steel and energy-conserving and environment-protective, while the glass fibre
Muscle causes support pile corrosion resistance to strengthen, and is especially suitable for the high ground environment of seashore chloride ion content.The invention enables muscle material profit
With than reaching maximization, in particular by glass fiber-reinforced polymer cost it is low, effectively reduce the cost of support pile, in addition institute
Glass fiber-reinforced polymer is stated compared to reinforcing bar more lighting, it is easy to transport and be easy to lift muscle cage when manufacturing, it is convenient and swift.
(2) present invention is compared with existing structure support pile, and in the case where meeting identical stressing conditions, arrangement of reinforcement quantity of the invention is big
Width is reduced, and cost is greatly reduced, wider using scope.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.

Embodiment
More specific detail is made to technical solution of the present invention with reference to embodiment：
As shown in figure 1, the present invention includes side close to the compressive region B of the tensile region A of soil layer and side away from soil layer, institute
State in the A of tensile region arrangement of reinforcement by constituted along the circumferentially spaced glass fiber-reinforced polymer 1 of support pile or by along support pile circumferentially alternately between
Constituted every the glass fiber-reinforced polymer 1 of arrangement with reinforcing bar 2；Arrangement of reinforcement is by along the circumferentially spaced reinforcing bar 2 of support pile in the compressive region B
Constitute；The glass fiber-reinforced polymer 1, reinforcing bar 2 be axially parallel to support pile axial direction.Support pile of the present invention is used in the A of tensile region
Glass fiber-reinforced polymer 1 or glass fiber-reinforced polymer 1 carry out hybrid reinforcement with reinforcing bar 2, and the reinforcement manner of use causes the usage amount of reinforcing bar 2
It is greatly decreased, saving steel and energy-conserving and environment-protective, while the glass fiber-reinforced polymer 1 causes the enhancing of support pile corrosion resistance, especially fits
Close the high ground environment of seashore chloride ion content.The invention enables muscle material utilize than reaching maximization, in particular by glass
The cost of fiber bar 1 is low, effectively reduces the cost of support pile, and the glass fiber-reinforced polymer 1 is lighter compared to reinforcing bar in addition
Change, it is easy to transport and be easy to lift muscle cage when manufacturing, it is convenient and swift.
Lateral side regions between the tensile region A and compressive region B are arrangement of reinforcement in the tectonic province C, the tectonic province C of support pile
By being constituted along the circumferentially spaced reinforcing bar 2 of support pile.
Arrangement of reinforcement quantity is more than arrangement of reinforcement quantity in compressive region B in the tensile region A.
By taking diameter 800mm support pile as an example, under identical stressing conditions, according to《Building pile foundation technical regulation》
(JGJ120-2012 Appendix B) calculates arrangement of reinforcement, and the present invention and the arrangement of reinforcement result of conventional support pile are as shown in the table：
Arrangement of reinforcement is along circumferentially spaced 6 glass fiber-reinforced polymers 1 of support pile by constituting in the tensile region A,
Arrangement of reinforcement is matched somebody with somebody by being constituted along circumferentially spaced 4 reinforcing bars 2 of support pile in the tectonic province C in the compressive region B
Muscle along circumferentially spaced 4 reinforcing bars 2 of support pile by constituting, and the glass fiber-reinforced polymer 1, the diameter of reinforcing bar 2 are respectively 20mm.
Calculate the present invention and the cost of conventional support pile below：
The glass fiber-reinforced polymer (GFRP)：Diameter 20mm, 7.5 yuan/m of price；
The reinforcing bar：Diameter 20mm, 10 yuan/m of price；
The concrete (C30)：350 yuan/m of price3, the volume V=3.14*0.4 of diameter 800mm support pile2* 10=
5.024m3。
The cost of support pile of the present invention is：
6*10*7.5+4*10*10+4*10*10+5.024*350=3008.4 members/root.
The cost of conventional support pile is：
20*20*10+5.024*350=5758.4 member/root.
As can be seen here, support pile of the present invention is in the case where meeting identical stressing conditions, and manufacturing cost declines to a great extent.
