Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tub for mounting a power equipment tower in an underground wiring pipe for burying and burying a block for performing electrical wiring and the like underground.

[0002]

Conventionally, electric wires such as power lines and communication lines are laid around electric poles. However, these electric poles reduce the effective width of the sidewalk and prevent safe and smooth traffic for pedestrians and the like. Had become. In addition, in the event of an earthquake or typhoon, the collapse of electric poles or the cutting of electric wires may cut off traffic or cause electric shock, which may hinder firefighting and evacuation activities. For this reason, in recent years, it has been practiced to bury a pipeline block in the ground to form a pipeline, and to insert electrical wiring into this pipeline for the purpose of urban disaster prevention problems and landscape improvement as described above. I have.

In such an underground wiring pipeline, a trench is formed by excavating the ground, and a pipeline block having a through hole formed at the bottom of the trench is arranged and buried. Power equipment towers are installed at intervals of to perform voltage transformation and interruption, but at the place where this power equipment tower is installed,
After once introducing the power line from the pipeline block to the power equipment tower, it is necessary to return it to the pipeline block again, and furthermore, it is necessary to stably install the power equipment tower and inspect it as necessary by an operator. For this reason, a so-called handhole is provided between the pipeline blocks for mounting the power equipment tower, and a power line is drawn into the handhole from one of the pipeline blocks and introduced into the power equipment tower. It is returned to the other pipeline block again.

[0004] Such a handhole mounts a power equipment tower, and is large enough to allow a worker to work therein, and because it is required to be earthquake-resistant, a measure of a certain size is made of reinforced concrete. At present, they are manufactured, transported to the site and buried. However,
Such a reinforced concrete handhole has a considerable weight, and there is a problem that transportation and burying work are difficult. In addition, it is necessary to provide the handhole with various functions such as a placement section for power equipment towers, a drop-in section for wiring, and steps for workers to enter during inspections. There is a problem that the productivity is remarkably reduced when a process for imparting each function is provided.

Therefore, it is conceivable that the handhole is of a split type. However, the handhole for the mounting basin of this power equipment tower is required to have a certain level of water resistance and seismic resistance, but simply assembling the divided handhole tends to cause misalignment, etc. Is not practical because it invades.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has been made in consideration of the above-mentioned problems, and has a simple installation and is excellent in waterproofing and seismic resistance. The purpose is to provide.

[0007]

According to the first aspect of the present invention, the mounting tub of the power equipment tower in the underground wiring pipeline is connected to a pipeline block through which wires such as electric wires and cables are inserted. A mounting basin for mounting a power equipment tower provided at a predetermined interval with respect to a road block, comprising two or more main body blocks constituting a main body, and a floor mounted on the main body. Plate, a tubular member for lid installation placed on the floor slab,
A power device installation tubular member is provided, and a projecting portion is formed on one side of a joint surface of each main body block, and a receiving portion of the projecting portion is formed on the other side.

[0008] By adopting such a configuration, since the measure main body is formed by connecting a plurality of main body blocks, it can be easily transported and workability at the installation location is improved.
In addition, a protrusion is formed on one side of the joint surface of the main body block, and a receiving portion for the protrusion is formed on the other side. The fitting can be easily performed by fitting to the receiving portion, and the waterproofness and the earthquake resistance at the joint surface are greatly improved.

In the underground wiring conduit according to the second aspect of the present invention, in the underground wiring conduit, the mounting block of the power equipment tower has a thin wall portion for forming a wiring entrance formed in the main body block, and each of the adjacent blocks has The main body blocks and the main body blocks and the floor slab are connected by connecting members. By employing such a configuration, it is easy to form the wiring entrance on site. Further, since the adjacent main body blocks are connected by the connecting member, the main body blocks connected to each other are less likely to be displaced, so that the water blocking property and the earthquake resistance are further improved. further,
Since each of the main body blocks and the floor slab are connected by the connecting member, the floor slab on the basin main body is fixed, and displacement and floating of the floor slab are prevented.

[0010] In the underground wiring conduit according to the third aspect of the present invention, there is provided a mounting tub for a power equipment tower, wherein a wiring receiver is attached to an inner side surface of the tub body, and a water hole is formed in a bottom surface. It is. By adopting such a configuration, the wiring can be introduced into the power equipment tower in an orderly manner, and the inspection can be easily performed. Therefore, the wiring can be suitably used as a mounting cell of the power equipment tower. Furthermore, since the bottom of the basin has a water reservoir hole, the wiring is not exposed to water even if water slightly enters the mounting basin.
