Construction principles of fire pipeline seismic support: 1. The underground space of subway project is narrow, and the involved electromechanical pipelines are various, including ventilation and air conditioning, building electrical, intelligent buildings, water supply and drainage, fire fighting, sprinkler, communication, signal and many other professional pipelines. Due to the variety of pipeline functions, the construction methods are different, There are air ducts, water supply and fire fighting ducts, high pressure water mist ducts, air conditioning cold water ducts, high and low voltage cable trays, communication signal trunking, lighting, control, monitoring and other conduits; The characteristics of pipelines are different, and the requirements for installation are different: such as strong current and weak current, pressure and non pressure, high pressure and low pressure, large pipe and small pipe, parallel and crossing, etc. If the layout is not unified and planned in advance, the conflict of pipelines in various disciplines will accompany the whole process of construction
2. When optimizing the integrated pipeline, the avoidance principles that can be followed by many parties have been formulated: 1) All professional pipelines installed on the integrated supports and hangers follow the general principle of "on power, in wind and underwater, small pipes give way to large pipes, pressure pipes give way to non pressure pipes, weak currents avoid strong currents, flexible pipelines give way to non flexible pipelines, and pipes that do not need frequent maintenance give way to pipes that need frequent maintenance", That is, when the pipelines are arranged in parallel, the pipelines of electrical equipment are located above, the air ducts of ventilation and air conditioning are located in the middle layer, and all water pipes are located in the lower layer
