Design of water supply and drainage for a grand theater
Abstract：The main content of this design for a grand theater building water supply and drainage engineering design,includes architectural water supystem,and fire extinguishing system.Building storey: one floor below ground, four floors above ground. Construction area 61805.82 ㎡, of which the building area is 21004.9 ㎡,and underground construction area is 41800.92 ㎡. The height of the building is 24m.Building classification: multi-storey public buildings. Access to a DN150 pipe from the municipal road as the living water sauce and switch in a DN80 inlet pipe as a reuse water source in this project.The rainwater sewer network is completed in this theater. The water supplyment of this project is provided by the municipal water pipe network, and the pressure of city pipe network is no less than 0.3 MPa.The maximum daily water consumption anduse is 71.5 m3 / d and 27.3 m3 / drespectivly.Fire extinguishing system mainly includes the fire hydrant water supply system, automatic spray fire extinguishing system, rain system， drencher system and large space intelligent active fire extinguishing system,and the indoor fire hydrant water consumption is 15 L/s, outdoor fire hydrant water is 30 L/s, automatic water spray extinguishing system of 35 L/s, rain system water is 125 L/s, drencher system water consumption is 25 L/s.The drainage system adopts the method that combines indoor sewage wastewater with water runoff system, and the outdoor sewage water separateed system. The maximum daily sewage discharge is 77m3 / d (90% of the water used in life).The living sewage is treated by the septic tank before drained to the municipal sewage pipe network. The system adoptsa combination of siphon rain and gravity rainwater.
