The present invention relates to a leakage prevention facility of a communication manhole, and more particularly, a door member for opening and closing the opening of the cavity through the manhole body is installed to prevent rainwater or foreign matter flowing into the manhole body from entering the cavity. Therefore, it is possible to prevent a short circuit accident, and when the cover member installed in the manhole body is seated, the door member can be closed by the pressing force generated by the self-weight of the cover member, thereby omitting the opening and closing operation of the door member. When the cover member is separated from the manhole body for work inside the cavity, the self-weight of the cover member is removed, and the door member is opened to facilitate the operator's convenience.

In general, a manhole is an underground structure installed in the middle of a pipeline for construction, inspection, and other maintenance work such as cable entry, withdrawal, connection, etc., and is installed at each intermediate distance or at the end of the apartment complex where the track is installed. .

The manhole is buried in the ground and is composed of a body such as concrete that has a space for wiring high-voltage cables, and a manhole cover that opens and closes the upper opening of the body.

Since manholes are often installed on roadways or sidewalks, manhole covers have been made of cast iron that can withstand the load of vehicles.

Therefore, there is a problem in that electric leakage occurs in a power line such as a high-voltage cable installed inside a manhole, and on a rainy day, electric shocks and deaths of passersby occur several times through electricity to the manhole cover made of cast iron.

In order to solve these shortcomings, a technique has been proposed in which the manhole cover is made of a material that does not conduct electricity. In the case of a manhole cover made of a material that does not conduct electricity, electric shock can be prevented, but because the manhole is installed in a place that receives a lot of load, the durability is very short because it cannot withstand the load transmitted from vehicles and pedestrians such as heavy equipment. Because of this, it is not practically used.

In addition, there is a problem that rainwater cannot be effectively blocked into the internal space of the manhole, so a large amount of rainwater is stored in the manhole after a certain period of time. Due to the above-described problem, the electric and communication lines located in the manhole are frequently damaged, and this causes electricity. Also, there is a problem that safety accidents often occur in which workers are electrocuted when repairing communication lines.

As a general manhole cover is disposed at the manhole entrance, when rainwater is generated, rainwater flows into the manhole through the space between the manhole cover and the inlet, thereby causing an electric accident.
