As optimization, pile body partly has manhole, and pile crown partly has the conical blind hole that communicates with the pile body manhole; The base portion end plate is connected with the sharp end plate of stake by the many equally distributed prestressed reinforcements that pass the prestressed reinforcement gripper shoe.So design, pile body partly has manhole, and pile crown partly has the conical blind hole that communicates with the pile body manhole, can guarantee structural strength, can alleviate the pile body deadweight again as much as possible.The base portion end plate is connected with the sharp end plate of stake by the many equally distributed prestressed reinforcements that pass the prestressed reinforcement gripper shoe, and pile body and pile crown be firm and support with the integral type prestressed reinforcement, and overall construction intensity is better, more convenient manufacturing.
As optimization, the described prestressed reinforcement that passes the prestressed reinforcement gripper shoe is 8, and wherein each middle part, one, every limit, place, four angles is each one; Be shaped on the reinforcing bar through hole on the prestressed reinforcement gripper shoe, the base portion end plate is shaped on the reinforcing bar through hole that a corresponding with it side has the reinforcing bar draw-in groove, also is shaped on the reinforcing bar through hole that the reinforcing bar draw-in groove is arranged in the circumferential equally distributed outside that is harmonious with it on the sharp end plate of stake.So design, the described prestressed reinforcement that passes the prestressed reinforcement gripper shoe is 8, and wherein each middle part, one, every limit, place, four angles is each one, and prestressed reinforcement is in the operation at stake point end plate place when then making with the least possible prestressed reinforcement is more convenient.Two ends have the reinforcing bar through hole of reinforcing bar draw-in groove then to make things convenient for tension reinforcing steel bar and fixedly allow reinforcing bar pass through through hole during the steel tension reinforcing steel bar, fixedly just reinforcing bar are clamp-oned in the draw-in groove during reinforcing bar, and the outer end reinforces clamp, cuts very convenient use again after maintenance is good.After reinforcing bar was clamp-oned draw-in groove, the through hole of vacating also can be used for being connected and fixed a top of a most advanced and sophisticated front edge of board, with other side's stake that links to each other with the base portion end plate, and promptly can the plug-in mounting alignment pin.
As optimization, the sharp end plate of stake also is shaped on center screw or through hole.So design, the top of more convenient equipped pile crown end.
As optimization, between base portion end plate and the prestressed reinforcement gripper shoe except that the main prestressed reinforcement by the sharp end plate of above sensible stake links to each other, also link to each other with the secondary prestressed reinforcement of prestressed reinforcement gripper shoe by the base portion end plate that is connected: prestressed reinforcement gripper shoe and stake point end plate is except that the main prestressed reinforcement by sensible base portion end plate links to each other, and is also continuous by steel frame.So design can improve overall construction intensity greatly.
As optimization, described reinforcing cage is formed by connecting by many axial prestress reinforcing bar and spiral reinforcements arranged side by side.So design, structural performance is better.
After adopting technique scheme, the pre-stressed concrete hollow square stake of the utility model band stake point has simple in structure, make easy to use, the vertical one of pile body stake point, can improve overall construction intensity greatly, significantly overcome out of plumb, displacement, the breakage defective that fractures, the advantage that pile quality significantly improves.
