DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a structure in which when a utility pole of a high-voltage power distribution line is damaged from the root due to a vehicle collision, natural disaster, etc., a pillar is built using the remaining portion of the utility pole and the remaining portion on the ground is used as a pillar. The present invention relates to a temporary support method for a broken power pole and a temporary support pole for the power pole, which enables quick restoration of power transmission.

[0002]

2. Description of the Related Art When a utility pole breaks near its root, a simple pile-shaped support pole is inserted using the tubular inner wall of the utility pole that remains in the ground for temporary restoration, and a gap is created between the inner wall and the support pole. There is a method in which earth and sand or solid matter is packed and fixed, and a broken utility pole is tied to the support pillar with a wire or the like.

And rotate the outrigger to the remaining part in the ground under pressure to fix the embedment part in an upright state, and then lift the utility pole support part 3 with a mobile crane to fit it into the upright embedment part and drop it. Fix it in a sewn way, and stand the temporary support upright on the remaining part in the ground. The subsequent work is the same as that of the above-mentioned embodiment.

[0032]

According to the temporary support method for a broken utility pole of the present invention, the outrigger remains in the ground by a simple operation of inserting the temporary support pole into the remaining portion of the breakable power pole and turning the rotary shaft in the support pole. It can be fixed to the inner wall of the part by pressure, and the pillar can be erected in an upright position.The ground remaining part of the broken utility pole can be brought close to the pillar using a crane, and the pole can be tightened with a chain, wire, etc. The temporary holding work of the ground remaining part of the broken utility pole can be performed in an extremely short time, and the power transmission can be promptly restored. Compared with the conventional method, the number of people is small and labor is not required, and the time is greatly shortened.

According to the temporary pole post of the present invention, when the rotary shaft is rotated by the operating means, the outriggers are evenly projected outward, for example, in four or six directions, through the actuating shaft and the undulating arms, and the holes in the remaining portion in the ground are opened. Since the column can be evenly pressed and fixed to the inner surface of the column, the column can be easily fixed to the remaining portion in the ground in the upright state, and the temporary support of the broken pole can be remarkably stabilized and the strength can be improved as compared with the conventional case. Therefore, even if it takes a long time to completely rebuild the building, its stable strength can be sufficiently maintained. When pulling out the temporary support poles for rebuilding with a new utility pole, simply rotating the rotary shaft in the reverse direction allows the outriggers to be retracted, and the support poles can be easily removed from the remaining part in the ground, enabling efficient rebuilding.

The vertically integrated type of the pipe body is heavier than the separated type, but the mechanical power of a crane or the like may be used, and the work of fitting and fixing the upper and lower parts is unnecessary. In addition, if the separated structure is used, the rotating shaft can be operated near the ground, and the rotating shaft and the supporting frame are not required in the utility pole supporting portion.
