- Abstract:
- By introducing the fire water supply system of the 416 project under construction in Nanjing, the design key points and regulatory disputes of the gravity fire water supply system for the over-limit high-rise building were discussed, and a gravity fire water supply system featuring simple logic, safe and effective operation, and easy testing was proposed. The intermediate water tank adopted the form of transfer and decompression to enhance the system’s resilience. The pressure reducing orifice plate on the gravity outlet pipe was configured to align with the discharge flow of the system’s design flow to prevent the valve group from frequently opening and closing. When the fire water supply system commenced operation, all transfer pumps initiated simultaneously, and the overflow piping system was integrated into the fire water supply system to establish a cycle flow. The system could be effectively utilized with both high and low fire water sources under diverse working conditions, and was capable of testing the reliability of the system over an extended period of time.
