摘要

本设计为重庆市快捷大酒店，是一幢16层的大酒店的设计，设计内容主要包括给水冷水系统、排水系统、消防系统、热水系统这四大块的设计。

室内冷水系统分为低区与高区两个区供水，低区为地下室至四层，由市政管网直接供水;高区为五层至十六层，根据要求,在地下室设生活水池，然后由变频泵抽水为高区供水。室内排水系统采用合流制，每个卫生间设置独立的排水立管，地下室至四层共有9根立管，五层至十六层为标准套房，卫生间布局一样，每层有34个房间，故共需34根立管，并且由于到四层时，这些立管位于办公室、商场等的房间中部，所以需另设立管，总计59根。消火栓系统不分区，在地下室设置消防水池，楼顶设置高位水箱。按照相关规定每层都需设置闭式自动喷淋系统，共分为五个区，水源来自于地下室的消防水池。另外，根据实际情况，综合考量之后,本酒店五层到十六层还需设置热水系统，热水供应方式采用集中供热，热媒采用蒸汽，采用半循环里面的干管循环系统。

关键词：大酒店，高层，给水系统，排水系统，消火栓系统，闭式自动喷淋系统，热水系统

Abstract

The design for the Chongqing express Le Grand Large Hotel, is to design a 16 - storey Le Grand Large Hotel, design content mainly includes these four large water supply water system, drainage system, fire control system, hot water system.

Indoor water supply system is divided into low and high two district water supply, low area as the basement to the four layer, by the municipal water supply pipe network directly; the area of five to sixteen layers, according to the requirements of life, a pool in the basement, and then pumped by frequency conversion pump for high water. Indoor drainage system adopt confluence, each toilet set independently of the drainage tube, the basement to the four layer consists of 9 vertical pipes, five layer to the sixteen layer as a standard suite, room layout, each floor has 34 rooms, so a total of 34 riser, and because of the four layer, the middle the room is located in the vertical pipe office, shopping malls, so need to set up a total of 56 root canal. Fire hydrant system does not partition, setting fire pool in the basement, roof water tank. In accordance with the relevant provisions of each layer shall be installed closed automatic sprinkler system, is divided into five zones, water from the basement of pool fire. In addition, according to the actual situation, comprehensive consideration, this hotel five layer to the sixteen layer also need to set the hot water system, water supply mode with centralized heating, heat medium with steam, with half cycle inside the stem vascular system.

Keywords: Le Grand Large Hotel, top, water supply system, drainage system, fire hydrant system, closed automatic sprinkler system, hot water system
