Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for removing an underground underground portion of a utility pole and a removal machine for removing an underground buried portion remaining after removing an above-ground portion of an electrical pole erected in an urban area or the like.
[0002]
[Prior art]
Electric poles erected in urban areas and the like need to be removed for renewal when their useful lives have elapsed. In recent years, there are many cases where electric wires have to be removed when they are buried underground due to the beauty of the streets and problems during urban redevelopment.
Conventionally, in order to remove such a power pole, the power pole is supported by a crane or the like, and the ground around the power pole is excavated with a hydraulic excavator, a breaker or the like, or manually, to expose the underground buried portion of the power pole, and then the crane. The electric pole has been pulled out from the ground. If it cannot be pulled out, the utility pole may be destroyed and removed from the base.
[0003]
In addition, a method of supporting the upper part of the utility pole using a special utility pole removal machine and cutting and removing the vicinity of the ground surface of the utility pole has been proposed (see JP-A-6-58020).
[0004]
[Problems to be solved by the invention]
In order to fully pull out the power pole using the machine, it is necessary to deploy many machines such as a crane that supports the power pole, a hydraulic excavator that excavates the outer periphery of the power pole, and a truck for unloading. Since it has to be taken, the work site which can use such a removal method is limited. In addition, since hydraulic excavators and the like are general-purpose machines, the excavation range becomes wider than necessary and the efficiency is poor.
[0005]
When many machines cannot be brought in on narrow roads, it is necessary to excavate manually, but excavation work by manpower is extremely difficult, inefficient and dangerous.
When the utility pole is destroyed and removed from the base, or when the utility pole removal machine is used to cut and remove the vicinity of the utility pole surface, only the ground portion of the utility pole is removed, and the underground buried part remains. Therefore, unless the underground part is allowed to be left as it is, it is necessary to excavate the outer ground of the utility pole and remove the underground part after removing the ground part.
[0006]
However, even when only the underground section is removed, if a hydraulic excavator or the like is used for excavation, it is a general-purpose machine, so the excavation range becomes unnecessarily wide and inefficient, and excavation work by human power is extremely difficult and inefficient. That is no different.
The present invention solves the above problem in the removal work of the utility pole, and can remove the work of removing the underground buried part of the utility pole anywhere efficiently and can reduce the cost of the removal work. It aims at providing the removal method and removal machine of the buried part of a utility pole.
[0007]
[Means for Solving the Problems]
In the method for removing the underground buried portion of the utility pole of the present invention, the auger drill having a hollow portion through which the utility pole can be inserted is used to excavate the outer ground of the underground underground portion of the utility pole, and the underground buried portion of the utility pole is clamped and lifted by the clamping device. By removing it, the above problems are solved.
[0008]
The method of removing the underground buried portion of the utility pole includes an auger drill having a hollow portion through which the utility pole can be inserted, a clamp device that clamps the underground buried portion of the utility pole, and a support device that supports the auger drill and the clamp device so as to be movable up and down. The removal machine of the underground buried part of the utility pole with
If this removal machine is used, it is possible to excavate the outer periphery of the underground buried part of the utility pole in an annular shape along the utility pole with an auger drill, so there is no need to excavate the outer periphery over a wider area than necessary, enabling efficient and safe drilling. It can be carried out, and after the excavation, the underground buried portion of the utility pole is clamped by the clamp device, and the auger drill and the clamping device are raised by the support device, and the underground buried portion of the utility pole can be easily pulled up and removed.
[0009]
If the removal machine uses a truck as a carriage and is equipped with a support device that supports the auger drill and the clamp device so that it can be moved up and down, and a crane for mounting on the vehicle, the removed electric pole will be buried underground It is possible to carry out all parts up to loading and transporting with one unit.
