DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underground single-port fire hydrant.

[0002]

2. Description of the Related Art Conventionally, an underground single-port fire hydrant is buried in an underground cavity, and a hose mounting portion is covered with a lid to prevent mud and sand from entering the valve. However, since it was only to prevent foreign matter such as mud and sand from entering, it protected only the base.
Mud or sand could get into the gap between the base and the remover, causing the remover to malfunction.
