建筑给水排水和消防设计说明书与计算书实例远洋大厦建筑给水排水和消防设计【设计总说明】本建筑主楼建筑高度为97.4米,共25层，地上23层,地下2层。

总建筑面积14880m2, 一层为4.7米，二、三层为4.3米，四层3.9米,五〜二十三层为3.8米,地下一、二层为4.0米,地下一、二层为地下车库辆，战时物资库；地下二层中还有设备泵房，配电室等。

一〜四楼为商场；五楼办公室及小型会议室；六〜^六层为办公室每层各有一小会议室，二十三层为多功能厅。

;I I给水系统由市政管网供水，采用市政直接供水和水泵两种供水方式相结合。

为了避免直接从市政管网抽水，本系统在地下层设置调节水池。

由生活给水泵从调节水池抽水至屋顶水箱，屋顶设置10吨不锈钢板水箱。

低区为一层至三层，由市政管网直接供水；四层到二十三层由屋顶水箱供水，采用上行下给的给水方式。

分为高区和中区，中区为四层至十一层，高区为十二层至二十三层，在十二到十三层之间的管道井中设置减压阀，保证中区水压安全。

水箱进水管设置两个浮球阀门，一备一用，根据水箱内水位变化控制水泵的启闭。

同时水箱需设置溢流管,高度为高于最高水位20到30mm,排至屋面。

采用污、废分流制排水，其中生活污水排入化粪池后进入市政排水管道，生活废水直接排到市政污水管网。

卫生间内，在地面坡度方向末端设置地漏。

排水横管管径小于De110的,清扫口的直径与管径相同；排水横管管径De110及以上的，清扫口直径取De110。

污废水立管合用一个专用通气管，而且按照规范规定专用通气立管每隔二层设H 管与污水立管相连。

按规范规定，塑料排水立管设置检查口，顶层底层各设一个外，其余每隔六层设置，检查口离地高度为1.0m。

屋面雨水单独排入市政雨水系统。

屋面雨水采用单斗内排水。

内排水的设计计算包括选择布置雨水斗，布置并计算连接管、立管、排出管和埋地管的管径。

采用集中热水供应系统，供应范围为二到二十三层卫生间，给水方式为上行下给式。

配水系统的泄气由系统中最上部的龙头在放水的同时进行。

采用卧式容积式热交换器，进水温度按5C计，出水温度为60 °C ,冷水由屋顶水箱供给。

为保证热水温度，在立管上设置回水管，采用立管循环方式。

回水管需低于立管顶端0.5m 接出。

本建筑物为二类建筑, 属中危险级。

分别设置消火栓系统和自动喷水灭火系统。

自动喷水灭火系统采用闭式自动喷水灭火系统的湿式喷水灭火系统。

消火栓系统分为高区和低区, 中间设置减压阀。

屋顶设置消防水箱, 储存十分钟消防水量18m3, 室外共设置五个水泵结合器, 经过消防车从室外消火栓补给室内消防系统, 其中三个供消火栓系统, 两个供自动喷水灭火系统。

水泵结合器离建筑墙的距离应保持在15 到40 米之间, 而且离马路保持2 米的距离为宜。

消防系统必须两路进水, 消火栓系统应成环布置。

室内消火栓系统采用并联给水, 减压阀分区。

消火栓口距地面高度为1.1m, 在五层与六层之间设置减压阀, 即地下二层到四层为低区, 五层到二十三层为高区。

为保证消火栓栓口处的出水压力不超过50米水柱, 在五层至十层之间的消火栓支管上设置减压孔板。

为了保证有两个木柱同时到达室内任何地方, 主楼室内消火栓的间距不应超过30 米, 裙房室内消火栓间距不应超过50 米。

因此, 主楼设有四根消火栓立管, 其中两根分别位于两个消防前室（消防前室必须设置消火栓） ;裙楼也设有一根消火栓立管。

高低区消火栓各自成环,同时相互成环, 分别位于二十三层、五层、四层及地下二层。

本建筑属于中危险级，其中地上部分为中危险级I级，地下一层、二层车库属于中危险级H级。

在建筑的办公室、商场、会议室等公共活动场所、走廊、地下车库等处均应设置闭式自动喷水灭火系统。

重要设备用房等不宜用水消防的部位设置二氧化碳或干粉灭火器。

地下车库和设备间采用直立式上喷式喷头, 其余均采用标准喷头。

共设四套湿式报警阀系统, 分别为地下二层到三层、四层到八层、九层至十三层、十四至二十三层。

To avoid directly pumping water from the municipal administration pipe n etwork, the system in stalled in the baseme nt regulat ing pond. From livi ng adjustment to the pump from the pond pumped to the roof tanks, roofs in stalled 10 tons of stai nless steel tanks. Low regi on ,1F to 3F, gets water from the municipal water supply pipe network directly; 4F to 23F gets water from the roof tank water. Divided into high regi on which is from the 11th floor to 23th floor and the middle region is from the 4th floor to the 10th floor. A pressure-relief valve is placed between the 12th floor and the 13th floor to guara nteed security zone pressure. Water mai ns in stalled into two float valves, one with a prepared, in accordance with changes in water level within the tank pumps control of the rising sun. Also be equipped with water tanks overflow pipe, above the maximum height of the water level from 20 to 30 mm, the way to roof.Use of sewage and waste divers ion drain age system, sewagedischarged into septic tanks entered the municipal drainage, wastewater directly into municipal sewage pipe network. Bathroom, the slope of the ground to set the direction of the end missed. Wang drainage pipe diameters less than De110 the sweeping mouth of the same diameter and the diameter; Wang drainage tube diameter De110 and above, sweeping from De110 diameter. Sewage and waste Standpipe shared a special ventilator. In accordance with the norms and provisions of legislation governing special ventilation located at the second floor of H sewage standpipe connected. According to norms, plastic drainage tube set up checkpoints, set up the top of the bottom one, the other at a six-storey establishment, I terrain clearance checks for 1.0 m.The rain water from the roof arranges into the municipal drainage systems. Use single roof rainwater inside drainage. Within the drainage design including the choice of rain bucket layout, layout and calculate pipe, risers, and the discharge pipe buried in the diameter. Centralized water supply system, the scope of supply for the 2-23floor toilet, The hot water supply method is from the top to the bottom. The gas will go out when the watercock is opened to use. Horizontal using volumetric heat exchanger inlet temperature is 5 °C , and the temperature of the hot water heater is 60 C . To ensure the water temperature in the legislation governing the installation of water pipes to use standpipe revolving basis. Return pipe below the required legislation governing the top 0.5 m taken part.This building is a second level building, which belongs to middle- dangerous level. There are fire hydrant system and automatic sprinkler system. Automatic sprinkler system uses closed automatic sprinkler system wet sprinkler system. Hydrant system is divided into high region and low region, middle pressure-relief valve installed. A fire water tank is placed on the roof of the building, which contains 18m3 water used to 10 minutes fire fighting. There are 5 pump joint apparatus supplying indoor fire water from fire fighting trucks, 3 of which are used to the fire hydrant system and 2 of which is used to the automatic sprinkler system. The pump joint apparatusmust be fifteen to forty meters far away from the wall of the building and be 2 meters far away from the roads best. Fire fighting-protection system must be two way flow and hydrant system should ring layout.In order to ensure a two poles indoor arrived at the same time anywhere in the main building indoor fire hydrant spacing should not be more than 30 meters, PODIUM indoor fire hydrant spacing should not be more than 50 meters. Therefore, the main building with four fire hydrant Standpipe, two of which are located at two fire before Room (Room before the fire hydrant must be installed); skirt building is also equipped with a fire hydrant Standpipe. Hydrant respective district level Ring, ring each other, which are located in the 23-storey, five-story, four-storey and two- storey underground. The building belongs to dangerous levels, as part of the ground dangerous first grade level, the ground floor was covered, two- story garage belonging to the dangerous level II class. In the construction of offices, shopping arcades, meeting rooms and other public places, the corridors, underground garage and other places should be set up closed automatic sprinkler system. Space and other important equipment is not appropriate water to the fire site set up carbon dioxide, or dry powder fire extinguishers.Underground garage and equipment used between vertical up-jet nozzle, and the rest were standard nozzles. The construction totaled approximately 2,700, which consists of four sets of wet alarm valve system for the upper ground floor of the three-storey four of the 8 th floor, chiutsengta to , 14 to 23layers.【Keywords 】Building water supply and drainage; Water supply system;Hot water system; Fire hydrant system; Sprinkler system目录1 设计任务及设计资料................................ 错误!未定义书签。
