Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a utility pole cap mounting tool for covering a top portion of a reinforced concrete utility pole above a live line with a cap.

[Conventional technology]

Conventionally, a concrete utility pole was formed by a centrifugal molding method, but a discoid finish member made of concrete was attached to the top of the pole, and the periphery thereof was solidified with mortar. Erect the concrete utility pole formed in this way,
Although it was distributing electricity to businesses such as factories and hospitals or households, the mortar part that had hardened the periphery of the disk-shaped finishing member was exposed to strong direct sunlight in the summer after a long period of time. Also, in winter, it freezes in the windswept and eventually fine cracks occur. Then, rainwater permeates the cracks, or the percolated water freezes, and the permeated water freezes to increase the volume, which greatly expands the cracks, and finally cracks and fragments of the size of pebbles occur. The broken pieces could be blown especially by the wind and fall from the top of the utility pole, hitting a car parked underneath and damaging it.

Therefore, I tried to put a cap on it in order to prevent the broken pieces from falling from the top of the pole, but it is very dangerous because the electric pole that is energized at high voltage is running through the pole. Unless I did, I couldn't do a safe cap work.
