It is equipped with connection screw thread.
As preferred：Described precast pile tip size is more than pile body, and precast pile tip is provided with steel immersed tube locating slot and ring sleeve pipe
Positioning table.
As preferred：Described prefabricated the size of the cover plate is more than pile body, and ring sleeve pipe insertion groove is reserved in prefabricated cover plate bottom.
The beneficial effects of the utility model are：
1st, ring tube-in-tube pile adopt bamboo joint type sleeve pipe, by one section one section telescopic joint form, solve common plastics sleeve pipe
Pile protection length of tube is difficult to control to lead to constructional difficulties.
2nd, ring sleeve belt is raised, improves the frictional force of common plasticses tube-in-tube pile and surrounding soil, thus improving carrying
Power.
3rd, ring jacket exterior posts conductive plasticss draining board, and the moisture in ground can be promoted to discharge ground from draining board
Base, dissipate the excess pore water pressure producing when constructing, and to solving, common plastics tube-in-tube pile soil extrusion in construction effect is highly effective.
4th, electroosmosis can promote the pore water between stake to flow to negative pole stake from positive pole stake rapidly, improves the carrying of inter-pile soil body
Power, also has preferable facilitation to dissipation excess pore water pressure simultaneously.
5th, because electric osmose can produce electrochemical action to the soil body, promote stake surrounding soil consolidation, improve pile body frictional resistance,
Increase the boundary strength between stake and the soil body.
6th, in precast pile tip, pre-buried connection reinforcing bar ensure that two conductive plasticss draining board conductive communication.On precast pile tip
Immersed tube groove is used for pushing pile body using steel immersed tube.
7th, pre- leaving a blank is provided with prefabricated cover plate and can ensure that drainage channel.
