- Abstract:
- The fire transfer water supply in the high-area of roof water tank transfer fire protection system can be implemented in three ways, the transfer water supply pipe doubles as the high-area transfer pipe, the high-area transfer water pipe is provided by a separate pipe network, the fire water supply pipe doubles as the high-area transfer water pipe, which connects with hand-lift pump and the high-area fire-fighting boosting pump adapter. There are differences among the three pipe connection methods in terms of ground fire truck operations, maximum fire water supply, rescue flexibility, and cost. The characteristics of these three pump adapters and transfer water supply systems connection ways are researched, using the high-area fire-fighting transfer water supply system of the roof water tank transfer fire protection system of a super high-rise residential community with a building height of 140-150 m in Guangzhou as the research object. When the roof water tank is used to transfer the fire protection system in a super high-rise building, it is recommended that the transfer water supply for the high-area fire-fighting system should be achieved by “using the fire water supply pipe doubles as the high-area transfer water pipe, connecting the portable pump and the high-area fire-fighting relay water pump adapter.” The number of hand-lift pumps and high-area fire-fighting boosting pump adapters should match the indoor fire-fighting system’s design flow requirements.
