Further, the hollow space of the pile body is provided with cross reinforcing bar, and the cross steel-bar arrangement is in distance
In 0.06 times of pile body top~long scope of 0.3 times of stake.
The beneficial effects of the utility model are：
1st, because using steel strand wires, as cage bar, steel strand wires have good ductility, can increase substantially the antidetonation of pile body
Performance, suitable for high-intensity earthquake fortification zone domain.
2nd, the construction period can be shortened by way of prefabrication, on-site consolidation, can be greatly lowered live manpower and
Construction cost, the problem of avoiding the bored concrete pile of cast in situs from existing.
3rd, the form of steel strand wires and ring flange is fixed using lockset, avoids the existing ring flange using big thickness, is reduced
The difficulty of processing and cost of ring flange, so as to reducing the cost of whole stake.
4th, the chuck set by ring flange and chuck and the combining form of screw thread, connection between lock tube and end plate is made more
It is firm, avoid the situation of lock tube disengaging occur during production tensioning and centrifugal forming.
5th, the wedge shaped shape of locking plate, it, which is internally provided with indentation, makes it more be fastened with being engaged for steel strand wires.
6th, when stake is higher than designed elevation after construction, after by pile head breaking, set dowel and cushion cap are direct
Connection, so as to realize the connection of stake top and cushion cap.
7th, set cross reinforcing bar makes stake can be used as the support frame of pallet when progress concrete fills out core, avoid existing
Field carries out the prefabricated of pallet again, improves the convenience of construction.
8th, the junction of lock tube and anchor hole sets protective case, can effectively prevent lock tube when anchoring the steel strand wires of major diameter
Destroy.
