- Abstract:
- The enhanced measures for improving the safety of the fire water supply system of buildings with height over 250 m were discussed. The relationship between building height and fire water supply system was analyzed. Fire extinguishing in high-rise buildings should be mainly depended on self-rescue, and fire technical measures should be changed with the building height. The design principles of safety improvement and the key factors of enhanced measures were clarified. The design needed to combine with the change of building height to propose targeted solutions, and it was suggested that special over-limit high-rise buildings with building height greater than 480 m should be treated separately. The framework of enhanced measures for fire water supply system of over-limit high-rise building was preliminarily established. According to the engineering design practice, the technical measures for enhancing the safety performance of fire water supply system in over-limit high-rise building were proposed from six aspects: system setup and application site, multi-source water supply system and facilities, system classification, zoning and pipe network components, design parameters and components selection, installation, intelligent operation, intelligent maintenance and management, and system evaluation.
