摘 要

本设计一层至地上四层为市政管网直供，五至十层为变频水泵水箱联合供水的给水方式。直供部分从市政给水管网接一根DN100的引入管，另一根DN100的引入管接至地下室生活水箱。生活水池为装配式不锈钢生活水箱，消防水池采用砖砌混凝土结构，放置于地下室。排水采用生活污、废水合流制。泵房排水槽经汇集排至地下一层污水井，经潜污泵提升排至检查井再经过化粪池处理后排入市政排水管。建筑里所有给排水横管在吊顶内，将各单元生活污水管适当汇集转换到排水立管后排出室外。屋面雨水经屋面雨水斗收集后由雨水管排入雨水管网。

根据规范，该建筑为二类建筑，属中度危险II级。室内消防流量20L/s，室外40L/s。充实水柱取12m，水龙带长度取25m，水枪喷嘴流量5.2L/s，消防立管管径为DN100、DN150。在顶层设试验消火栓一个，每个室内消火栓箱内均设有远距离启动消防泵的按钮。

该建筑采用湿式自动喷淋灭火系统，报警阀设于地下一层，各层均设水流指示器和信号阀，其信号均送入消防控制中心进行处理。各层均采用自动喷淋系统，地下一层采用下垂式喷头。各层均设末端试压装置以及放空管。本工程的自动喷水灭火系统分3个区。屋顶水箱为12立方米，，贮存有生活、10min自动喷水灭火系统用水量。自动喷水灭火系统和消火栓系统的初期灭火由水箱供水，后期供水由地下室的消防水泵和自喷泵供水，各支管与立管连接处设置减压孔板。

根据重力式雨水系统和虹吸式雨水系统的设计分析及造价对比后，本设计采用重力式屋面雨水排水系统。

Abstract

The design of the first floor to the four floor for the municipal pipe network direct supply, five to ten layers for the frequency conversion pump water tank joint water supply mode. Directly from the municipal water supply pipe network to connect the introduction of a DN150 tube, the other two DN100 of the introduction of pipes connected to the ground floor of a living pool and fire pool. The living pool is an assembly type stainless steel water tank, and the fire water tank adopts the brick concrete structure and is arranged in the basement. Sewage using living sewage, waste water combined system. Pump drainage groove by pooling row to the underground a layer of sewage wells, the submersible sewage pump up and drained to the inspection well after treatment of septic tank drainage of discharged into the municipal pipe. All the water supply and drainage horizontal pipe in the building is in the ceiling, and the living sewage pipe of each unit is properly collected and converted to the outside of the water supply pipe. The roof rainwater collected from roof drain rain water pipe row to the ground for water.

According to the specification, the building is two types of buildings, is a moderate risk level. Indoor fire flow 20L/s, outdoor 40L/s. Enrich the water column 12M, 25m hose length, gun nozzle flow 5.2L/s, riser diameter is DN100 and DN150. On top of the test set a fire hydrant, fire hydrant box each are equipped with remote start the fire pump button.

The building adopts wet automatic sprinkler system, alarm valve is located in the ground floor, each layer has a water flow indicator and signal valve, the signal is sent to the fire control center for processing. Each layer adopts automatic spraying system, and the underground layer adopts the drop type spray head. Each layer were set at the end of the pressure testing device and vent pipe. The automatic water spraying fire extinguishing system in this project is divided into 3 zones. The roof water tank is 12 cubic meters, and the water consumption of the automatic water spraying fire extinguishing system is stored in the 10min. Automatic sprinkler system and fire hydrant system of early fire extinguishing by water supply, post water from the basement of the fire pump and sprinkler pump water supply, each branch pipe and pipe arranged at the connecting position of decompression orifice plate.

According to the design analysis and cost comparison of the gravity storm water system and the siphon rainwater system, this design uses the gravity type roof rainwater drainage system.
