Outline
Traditional fire water supply systems in super high-rise buildings face several challenges, including high hydrostatic pressure, poor water supply timeliness, insufficient system reliability, and limited tactical flexibility. The dry fire standpipe system offers advantages such as low risk, high flexibility, and ease of maintenance, serving as an effective and important tactical supplement and redundancy solution. This paper analyzes the working principle and core advantages of the dry fire standpipe system, characterized by "empty pipe in normal times, water supply in disasters", and demonstrates its technical feasibility by combining domestic fire truck water supply capabilities with field test data. The study focuses on the feasibility and technical pathways for converting temporary fire hydrant standpipes or concrete pump pipes from the construction phase into permanent dry fire standpipe facilities, and proposes specific design recommendations for dry fire standpipe systems in super high-rise buildings. The analysis shows that, when combined with the immediate response mechanism of building mini-fire stations and supported by rapid water supply from fire trucks, the system can achieve effective water supply within 5 minutes after fire confirmation, meeting the "golden time requirements for initial fire control" in super high-rise buildings. This study aims to provide new ideas and technical references for improving the efficiency of firefighting in super high-rise buildings.
