某建筑工地火灾隐患分析与消防设计(3)
Fire water is set up a temporary fire water supply system, the basic conditions required to be provided on or near the construction site stable and reliable water supply, and should meet the needs of the construction site temporary fire water. Fire water can be used for public water network or natural water sources, while the use of natural water sources, measures should be adopted to ensure that the frozen season, well water when the dry season the lowest level, and to meet the requirements of temporary fire water. The design selected for the fire water about 100m away from the construction site of the river.
Automatic fire alarm linkage control technology is an integrated fire control technology, is an important and emerging technologies and modern automatic fire discipline techniques. Automatic fire alarm system in the building design is an important aspect. It relates to an automatic fire alarm system type selection, determine the method of fire detection, fire detector selection, system engineering, fire equipment joint control several aspects of implementation and distribution systems and other fire constitution. Selection of the design smoke detectors, mainly for temporary buildings, such as dormitories, offices, warehouses and other inflammable and explosive dangerous goods. The mounting pitch limit graph shows the distance between each probe to determine the layout.
Selection is based on the type of fire extinguisher main fire scene to design, known from the design specification, each region may start a fire hazard level, and then determine the area of fire extinguishers set points, after the calculation formula to determine the region arrangement required several fire extinguishers, furthermore determine the type of fire extinguisher, which completed the construction site of the fire extinguishers configuration.
