[6. Electric pole erection method]
The pole erection method of the present invention comprises a pole erection preparation step performed before erecting the utility pole P, and a pole erection main step of actually erecting the utility pole.

[6-1. Pole erection preparation process]
In the pole erection preparation process, first, as shown in FIG. 2, after the cylindrical body 1 is placed vertically as shown in FIG. 2, the circumference of the cylindrical body 1 is filled with soil produced by excavating the foundation hole H (cylindrical body installation step). The rest of the soil generated by the excavation of the foundation hole H is placed in the soil containing member 5 and temporarily placed at an appropriate place around the foundation hole H, for example.
Next, as shown in FIG. 3, after filling the inside of the cylindrical body 1 buried in the ground G with a plurality of temporary stuffing members 2 until it is almost full, the top opening of the cylindrical body 1 is covered. The soil containing member 5, which is covered with the member 3 and finally filled with soil, is moved from the previously temporarily placed place and placed on the lid member 3 (cover closing step).
In this state, even if it is left for several hours until the next main erection process (usually several hours until the start of work on the next day) or for several days waiting for the weather to recover, people, garbage, etc. will fall into the foundation hole H. There is no fear, and since the soil containing member 5 placed on the cover member 3 is weighted, it is difficult to shift, so that the foundation hole H is effectively prevented from being mischievous. In particular, if the cover member 3 is entirely hidden by the soil containing member 5 placed on the cover member 3, there is no fear of stimulating passers-by's curiosity about the cover member 3 unnecessarily. The mischief that tries to open the door is also less likely to be induced. Moreover, since the periphery of the lid member 3 is covered with the soil containing member 5, it is effective in suppressing the infiltration of rainwater. In particular, when the soil containing member 5 is waterproof, it covers the lid member 3 in a state like an open umbrella, which is effective in suppressing rainwater infiltration.
Moreover, even if the lid member 3 is removed or is removed by mischief or the like, the cylindrical body 1 is filled with the temporary stuffing member 2, so there is no risk of accidental dropping.

[6-2. Pillar erection process]
Next, after a few hours from the end of the pole erection preparation process, if weather conditions are met, the pole erection main process will be carried out on the next business day. The utility pole P is brought into the site in accordance with this pole erection process. First, the lid member 3 is removed from the top opening of the cylindrical body 1 except for the soil containing member 5 on the lid member 3, and all the temporary stuffing members 2 are taken out from the cylindrical body 1 (cover opening step). In addition, since this temporary stuffing member 2 can be reused in the next erection of the pole, it is collected as it is.
Next, as shown in FIG. 4, the electric pole P is vertically lifted by a crane (not shown) and inserted into the cylindrical body 1 from the top opening, and the electric pole P and the cylindrical body 1 are interposed between the electric pole P and the cylindrical body 1 as shown in FIG. is filled with soil 4 in the soil containing member 5 to fill the gap S (fixing step).
According to this pole erection method, the cylindrical body 1 remains buried in the ground G together with the utility pole P and becomes disposable. may be filled with soil 4 and buried. In that case, if the cylinder 1 shown in FIG. 6 which can be divided is used, the cylinder 1 can be pulled out from the base hole H to the ground and the flange piece 10a can be removed without lifting the cylinder 1 up to the top of the utility pole P and pulling it out. , 10a are removed, and the tubular body constituent members 10, 10 can be easily removed from the utility pole P by separating them. Since the cylindrical body 1 pulled out from the foundation hole H in this way can be reused multiple times, it is effective in reducing the cost of erecting the pole.

As described above, the pole erecting method of the present invention has been described with reference to the embodiments, but the present invention is of course not limited to the above embodiments. For example, in the embodiment, a utility pole P is shown as a columnar work, but the present invention can also be applied to erecting poles such as supports for large signboards.
Further, in the embodiment, the soil generated by excavating the foundation hole H is put into the soil storage member 5, and the soil is filled between the cylindrical body 1 and the utility pole P or between the foundation hole H and the utility pole P, In this way, there is no need to waste money on transporting soil, but if there is a problem with the soil at the site, separately procured soil is put in the soil storage member 5. good too.
Further, in the embodiment, the soil containing member 5 is formed as a single body, but a plurality of soil containing members 5 may be piled up so that the cover member 3 is hidden as a whole assembly.
