- Abstract:
- The design of airport outdoor underground fire hydrant well in severe cold area of north China always have the problems of contradiction between design code and national standard atlas and difficulty in practical design. Traditional design schemes make it impossible for firefighters to operate on the ground, increasing the operational time and difficulty of fire rescue operations. According to the survey, most of the current fire hydrant wells have the problems of water accumulation in the well and manhole cover difficult to open in winter. For this reason, three optimization schemes including expanding wellhead, double-layer insulation manhole cover and double wellbore were proposed to solve the problems of inconvenience for firefighters to get down the well and difficulty in opening the fire hydrant. In addition, the construction scheme was optimized through improvement measures such as water-proof on the outer wall of the well, selecting water-proof manhole cover and adding spraying in the well, which provided a new idea for the design of outdoor underground fire hydrant well in severe cold area.
