建筑给水排水设计方案.doc

给水排水设计,该建筑物为中危险级建筑，给排水设计及消防要求较高。 该建筑层高为地上八层，地下一层，，建筑总高度为31.80米，总建筑面积8563平方米，要求设计的给排水系统为：室内给水系统，室内排水系统，室内热水系统,消火栓给水系统和自动喷淋灭火系统共五个系统。 1、生活冷水给水系统 采用高、低分区，低区由市政管网直接供水，高区由水箱—水泵联合供水。 2、排水系统 根据楼内结构要求，2-6层均在管道井内设排水立管，为多立管排水系统。在首层吊顶内设横干管至地面下排出，整个系统采用汇合通气管伸顶通气，公共卫生间的排水设单立管排出，通气系统采用普通伸顶通气管通气。 3、热水供应系统 利用蒸汽为热媒，在地下一层设半即热式汽—水交换器、热水补水泵及热水循环泵。 4、消火栓给水系统 各层消火栓均靠立柱并设在走廊内，由水泵加压供水，报警阀设在地下一层的泵房内，屋顶设水箱及气压罐。 5、自动喷淋灭火系统 除公共卫生间和地下一层之外均设自动喷淋灭火系统。 关键词：毕业设计、给水系统、排水系统、热水系统、消火栓系统、自动喷淋系统 Abstract This design topic is a hotel in Zhengzhou to set up the water supply drains the design.That building is inside the dangerous class construct, giving drain design and fire fights request to be higher. Should construct the story high is last for ground 8 layer,underground 1 layer, construct total high degree is 31.8 rice, design of to drain system is: cold water supply system, drain the system, hot water supply system , the fire of bolts the water supply system and sprays to pour to extinguish fire the system automatically five systems totally. 1. Cold water supply system. Adoption top, next cent area, descend the area be taken care of by municipal net direct supply water, top area from water tank — water pump unite water supply. 2. Drain the system. Request according to the construction inside the floor,2-6 layers all establish the catchment tube in piping well, draining the system for many tube.Establish in a layer hanged crest horizontal the tube concentrates to eject, this system all adopts the join stretches the crest ventilates the tube ventilates. the comfort station descending each catchment of area order to establish the single tube ejects and adopts the commonness stretches the crest ventilates t
