给排水及消防系统在土建预留中的细节讨论及对策

Discussion and Discussion on the Details of the Metro Water Supply, Drainage System and Fire-extinguishing System in Reserve for Civil Construction

介绍了地铁给排水及消防系统设计的概况,分析各系统的特点。指出地铁给排水设计各系统在房间配合及孔洞配合的特点,消防系统配合时应考虑消防水池的有效容积及各消防设备的占地尺寸问题;排水系统配合时应考虑雨水、污水及废水等系统排水泵坑的下沉及孔洞预留问题;给水系统配合时需考虑在供水压力不足时供水泵房的配合设置;气体灭火系统配合土建时应同时考虑受保护房间及气瓶间的合理设置。对各系统设置的楼板套管、人防套管及穿墙套管预留问题,提出相应的观点。

The design of water supply, drainage system and fire-extinguishing system in Metro is introduced, analyze the characteristics of each system. The characteristics of room matching and hole matching in the design of subway water supply and drainage system are pointed out. Fire-extinguishing System should consider the effective volume of the fire pool and the size of the fire-fighting equipment. Drainage system should consider the settlement of the drainage pump pit and the reservation of the hole when the drainage system is combined with the rainwater, sewage and waste water. Water supply system should be considered when the water supply pressure is insufficient. The gas fire extinguishing system shall consider the reasonable arrangement of the protected room and the gas cylinder in coordination with the civil construction. This paper puts forward the corresponding viewpoints on the arrangement of the floor tube, the air defense sleeve and the through wall casing of each system.
