The utility model is to buckle the clamping column to the inner side of the circular hole set on both sides of the connecting groove, so that it is fixedly connected to the support rod and the connecting rod, so that the device is convenient to assemble and connect for use, and the expansion column is pushed to expand by the adjustment rod, so that the expansion column is buckled in the ground, so that the device is firmly fixed. When the poles of the above structure are in use, although the underground fixation of the poles is improved, the height requirements of the poles are different when they are in use, which sometimes leads to the need to connect the poles to increase the length of the poles. In addition, sometimes, in order to facilitate the transportation of the poles, connectable poles are also used. Therefore, a ring-shaped partially prestressed recycled concrete pole is needed to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, a ring-shaped prestressed recycled concrete pole is provided, which can quickly solve the problem of rapid docking between poles, facilitate the transportation of poles, and improve the overall convenience of pole use.

[0005] The utility model adopts the following technical solution to solve the technical problem: an annular partially prestressed recycled concrete pole, comprising a pole body with a conical structure, wherein the pole body is a hollow structure, and a first docking hole and a second docking hole are respectively arranged at the upper end and the lower end of the pole body, and the pole bodies are docked by end-to-end plug-in connection; the overlapped portion of the first docking hole and the second docking hole is fixed by passing bolts.

[0006] It is further defined that, in the above technical solution, the first docking holes and the second docking holes are evenly arranged along the circumferential direction of the rod body.

[0007] It is further defined that in the above technical solution, the first docking hole and the second docking hole are both waist-shaped hole structures; this can facilitate their rotational positioning after alignment and insertion.

[0008] It is further defined that, in the above technical solution, a first protective cover is installed on the outer side of the second docking hole, which can effectively protect the connection.

[0009] It is further defined that, in the above technical solution, a second protective cover is also installed on the outside of the first docking hole, which can effectively protect the connection.

[0010] It is further defined that, in the above technical solution, the second protective cover is embedded in the first protective cover for fixation; it can provide effective protection after the connection is closed.

[0011] It is further defined that, in the above technical solution, a slope surface is arranged on the upper part of the first protective cover; such design is to achieve a waterproof effect and avoid leakage caused by accumulation of rainwater over a long period of use.

[0012] The beneficial effect of the utility model is that the annular partially prestressed recycled concrete pole proposed by the utility model can quickly solve the problem of rapid docking between poles, facilitate the transportation of poles, and improve the overall convenience of pole use.
