The diameter of described semicircle shape hollow steel pipe is 600-800mm.
The wall thickness of described semicircle shape hollow steel pipe is 28-36mm.
The spacing of two adjacent rectangle double wedges is 200-300mm on the axial section of described semicircle shape hollow steel pipe.
The described steel making of having strong market potential to be not less than the secondary steel, its diameter is 24-32mm.
Described pin-and-hole can be screwed hole, and described screwed hole is used for two semicircle shape hollow steel pipes are fixed with the stay bolt that axially runs through rectangle double wedge on two described semicircle shape hollow steel pipes when being combined into steel pipe pile.
Described stay bolt is made with the steel that are not less than the secondary steel, and its specification is M24-M32.
The beneficial effects of the utility model are:
(1) remedied the defective of bored pile and concrete pile anchor structure, to guarantee the safety of pattern foundation pit supporting structure.
(2) realized recovery and the recycling of foundation pit supporting construction, thereby reduce project cost shortens construction period, avoids the foundation of top-out to be destroyed, and has good practicality.

The specific embodiment
The utility model is easier to be understood in order to make, and below in conjunction with drawings and Examples the technical solution of the utility model is described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3, recyclable pattern foundation pit supporting structure pile tube in the technical solutions of the utility model, comprise two semicircle shape hollow steel pipes 1, alternate rectangle double wedge 2 and the recessed tooth 2 ' of rectangle of arranging respectively on the axial section of two described semicircle shape hollow steel pipes 1, when two 1 pair of described semicircle shape hollow steel pipes were combined into steel sheet pile, staggered rectangle double wedge 2 and the recessed tooth 2 ' of rectangle in position can agree with mutually on its axial section;
Be respectively arranged with pin-and-hole 4 on the described rectangle double wedge 2, the center line counterpoise of pin-and-hole 4 is combined into one on two described semicircle shape hollow steel pipe 1 all rectangle double wedges 2, the pin-and-hole 4 of this central lines 3 is fixed axially to run through having strong market potential of rectangle double wedge 2 on it when being used for that 1 pair of two semicircle shape hollow steel pipe are combined into steel pipe pile.
The diameter of described semicircle shape hollow steel pipe 1 is 600-800mm, and the wall thickness of described semicircle shape hollow steel pipe 1 is 28-36mm, and the spacing of two adjacent rectangle double wedges 2 is 200-300mm on the described semicircle shape hollow steel pipe 1 axial section.
Described having strong market potential 3 made with the steel that are not less than the secondary steel, and it is 24-32mm that the utility model arranges its diameter.
The pin-and-hole 4 that arranges respectively on the rectangle double wedge 2 of two described semicircle shape hollow steel pipes 1 also can be screwed hole, is fixed with the stay bolt that axially runs through rectangle double wedge 2 on two described semicircle shape hollow steel pipes 1 when described screwed hole is used for that 1 pair of two semicircle shape hollow steel pipe are combined into steel pipe pile.
Described stay bolt is made with the steel that are not less than the secondary steel, and its specification is M24-M32.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, use and the recovery method of the recyclable pattern foundation pit supporting structure pile tube of the utility model may further comprise the steps;
