MANHOLE STRUCTURE FOR FLOODING PREVENTION

The present invention relates to an inundation-preventing manhole structure, and more particularly, a bottom plate having a plurality of through holes formed in a receiving portion formed in the manhole body, and a chamber coupled to cover an upper portion of the bottom plate in a cup shape. It relates to a flooded prevention manhole structure in which water does not flow into the interior of the chamber even though water is introduced into the receiving portion of the manhole body.

Due to the rapid industrialization and urbanization of the modern society, the demand for electric power has exploded, and facilities such as electric power facilities such as Jeonju appear in the vicinity of the city, spoiling the aesthetics of the city and hindering the efficient use of urban space. It has been acting as a factor that threatens the safety of people.

In consideration of this, underground power is currently being installed underground, but electric wires are buried underground, but related power facilities are mostly installed on the ground because they cannot solve problems such as flooding, moisture, and temperature. .

The installation of various electric power facilities on the ground prevents pedestrians from passing, and in the case of shopping malls, it is difficult to install electric power facilities in front of the mall. In addition, administrative offices do not give occupancy permits on the sidewalks for civil complaints, pedestrian passes, and urban aesthetics, and since unnecessary permits are required to construct additional facilities because they give permission to nearby green spaces or empty spaces away from places where actual facilities are needed. Not only is the initial investment cost high, but maintenance and repair costs are high.

In order to solve the problems of the existing manhole, a manhole serving as an underground storage is buried in the ground and a method of storing power facilities or other facilities inside the manhole is adopted, and to solve the heat and moisture generated from the power facilities or other facilities. In order to ventilate in a natural convection manner, air intake and exhaust ports were used.

However, in the existing manhole, since the intake and exhaust ports are formed on the ground of roads or sidewalks, in the hot summer season, geothermal heat flows into the intake, so it does not help heat dissipation of power facilities and other facilities, thus shortening the life of power facilities or other facilities. There is a technical disadvantage that it is essential to provide a drainage-related device because rainwater flows into the intake and exhaust ports as water fills the ground when there is a lot of rain.
