Description

Underground fire hydrant box system

The present invention relates to a fire hydrant system for underground burial.

In general, fire-fighting facilities are provided in each building to prevent property damage and human injury caused by fires in the building. In buildings and apartments, indoor fire hydrants are installed at specific locations on each floor according to the Act on the Installation, Maintenance, and Safety Management of Firefighting Facilities. It plays a very important role in suppressing accurately.

A fire hydrant can include a fire hydrant with a watertight outlet, a fire hose of a standard suitable for the scale of a building, and a window for spraying water directly into a flame. In the event of a fire, a fire hydrant can quickly extinguish a fire using a fire hydrant. .

The above-described fire hydrants are in recent years installed in conventional markets or residential areas where multi-family houses are concentrated, and this trend is complicated enough that fire trucks cannot quickly enter the vicinity of conventional markets. It is installed, but there is no fire hose including a window for directly spraying water, so the initial response to the fire is insufficient, and as a result, a small fire spreads into a large fire, resulting in a problem that social loss increases. In order to solve such a problem, a fire hydrant box capable of storing a fire hose including a pipe window has been installed.

In addition, if the above fire hydrants are installed in a residential area where multi-family houses are concentrated, the location of the fire hydrants can be determined even if the fire trucks cannot enter the fire zone by cars parked on the back road. A fire hydrant is installed so that only firefighters can go to the fire hydrant and take out the prepared fire hose to extinguish the fire early.
