Specific embodiment
Below, with reference to accompanying drawing and specific embodiment, the utility model is described further：
As shown in Figures 1 to 4, a kind of prestressed concrete precast hollow square pile, including pile body, be divided into pile body two ends use
In the end plate 1 for connecting different square piles and it is connected between pile body and end plate 1 and is used to strengthen end plate 1 and pile body connective stability
Skirtboard 2, the cross section of pile body is square, and the pile body is made up of steel reinforcement cage 3 and concrete 4, and reinforcing bar is fixed in the cast of concrete 4
Cage 3, steel reinforcement cage 3 includes multiple deformed bars 31, multiple nonprestressed reinforcements 32 and is intervally arranged along pile body short transverse
Multiple stirrups 33；Each deformed bar 31 and each nonprestressed reinforcement 32 extend along the short transverse of pile body, each prestressing force
Reinforcing bar 31 is spaced the inner edge for being fixed on stirrup 33, and nonprestressed reinforcement 32 is fixed on the inner edge of stirrup 33 and is located at adjacent two in advance should
Between power reinforcing bar 31, stirrup 33, deformed bar 31 and nonprestressed reinforcement 32 are surrounded along hollow netted of pile body short transverse
Structure.
When using, using the one side in steel reinforcement cage 3 with deformed bar 31 and nonprestressed reinforcement 32 as weight-bearing surface, use
In the weight for carrying external buildings, wherein, stirrup 33, deformed bar 31 and nonprestressed reinforcement 32 are surrounded along pile body highly
The hollow network structure in direction can ensure that steel reinforcement cage 3 has the structure of stabilization；Due to there is prestress steel simultaneously on weight-bearing surface
Muscle 31 and nonprestressed reinforcement 32, and nonprestressed reinforcement 32 is fixed on the inner edge of stirrup 33 and positioned at adjacent two deformed bar
Between 31, and the good ductility of nonprestressed reinforcement 32 itself is in the preferable anti-bending strength of deformed bar 31, can be with
