有关宾馆给排水设计

摘要

本设计是某十层宾馆的建筑给排水设计，包括给水系统、排水系统、消防系统、热水系统。建筑高度为34.2米，总建筑面积约7823.36平方米。本建筑物所有给水排水均按高层建筑给排水要求进行设计。结合实际情况，根据建筑物的性质，用途，和室内设有完善的给水排水卫生设备，具体的给排水系统设计如下：给水系统采用水泵水箱水池联合供水的方式。由于消火栓超过十个，需设两条引入管。

排水系统采用污水废水合流制，排出水排入市政污水管网。底层单独排水，排水立管设有专用通气管。

该建筑防火等级属于中危险级Ⅰ级，设计内容包括消火栓系统，在屋顶水

箱间内设实验用消火栓装置，消火栓给水管网呈环状布置，各消火栓箱内设消

防水泵启动电钮，能直接启动消防泵；室外设地下式水泵结合器，保证消防安

全可靠。消防系统采用临时高压供水。消火栓系统设有五根立管，采用单栓。

热水系统采用开式机械全循环系统，上行下给。

Resign of Building Water Supply and

Drainage for a Hotel

Abstract

The is a design of duilding water supply and drainage for a 10-story hotel, including water supply system, drainage system, fire protection system, hot water system . It is highly 34.2 meters, total floor space approximately 7823.36square meters.

Water supply system using by pump-tank. Because the fire hydrant surpasses ten, must suppose two lead-in tubes.

The combined system is used for the drainage system.The bleed-off sewage dispersing into the municipal sewage pipe network.The first floor drains water alone and the draining vertical pipe is equipped with specific vent stack.

This building fIre protection rank belongs to the dangerous levelⅠthe level, the design content including the fire hydrant system, sprays automatically with the water curtain system. In supposes the experimental fIre hydrant installment in the roof water tank between, the fIre hydrant service pipe net assumes the rimg-like arrangement, in various fIre hydrants box supposes the fIre pump to start the push-button, can the line start fIre extinguishing pump; Room peripheral equation below water pump coupler, guarantee fIre prevention safe reliable.

The fire supply system is the fire hydrant system useing the temporary high-pressured water supply. The fire hydrant system is equipped with three pipes, using the single hitch.

A open mechanical complete alternation system is used for the hot water system. Whose vercical dirision block is the same as the water supple system.

Key words: building water supply system; drainage system; fire supply system;

hot water supply system.
