Description

ELECTRIC MANHOLE FOR PROTECTING ELECTRIC LEAKAGE < RTI ID = 0.0 >

The present invention relates to an electrical leakproof electrical manhole in a residential complex, and is intended to prevent penetration of rainwater into a storm generator such as a typhoon or a rainy season, and to allow rainwater to be infiltrated to be discharged to the outside, Thereby preventing the rainwater or foreign matter from flowing into the inside of the manhole efficiently. In order to prevent tilting caused by continuous and repetitive load applied to the vehicle such as heavy equipment or dump truck, In a housing complex in which a leakage current can be maintained.

In general, a manhole is an underground structure to be installed for the purpose of construction, inspection and other repair work such as cable entry, withdrawal, and connection in the middle of the pipeline. The manhole is installed at an intermediate distance or at an end do.

The manhole is embedded in the underground, and has a body such as concrete having a space in which a high-voltage cable is wired, and a manhole cover for opening and closing the upper opening of the body.

Since the manholes are often installed on the roads or on the roads, the manhole covers have been made of cast iron that can withstand loads such as vehicles.

Accordingly, there is a problem that electric shocks and deaths of passengers are generated several times on the manhole cover of the cast iron when electricity is leaked from a power line such as a high-voltage cable installed in the manhole.

In order to solve such disadvantages, a technique has been proposed in which a manhole cover is made of a material that does not allow electricity to pass through. In the case of a manhole cover which does not allow electricity to flow, it is possible to prevent an electric shock accident because electricity is not applied. However, since the manhole is installed in a place where the load is heavy, the durability is very short because it can not withstand loads transferred from vehicles such as heavy equipment and pedestrians It is impossible to use it realistically.

In addition, when installed in an electric or communication manhole, it is not possible to effectively block the storm coming in from the outside. When a certain period of time elapses, a large amount of storm is accumulated in the manhole. There is also a problem of breakage.

In addition, there is a problem that a safety accident where the operator is electrocuted when repairing the electric or communication line is frequently generated.

The general manhole cover is disposed at the entrance of the manhole, and when rainwater is generated, the rainwater flows into the manhole through the space between the manhole cover and the entrance so that an electric accident occurs.
