项目概要

深圳地铁5 号线BT 项目由前海湾经宝安中心、新安旧城区、西丽、大学城、最后到黄贝岭。线路全长40.001km，其中 地下线路35.801 km，高架线路3.424 km，过渡段0.776km。共设27 座车站，其中地下站25 座，地上站2 座，平均站间距约1.454km。

本标段工程内容为五个地下站（前海湾站、临海路站、宝华路站、宝安中心站、翻身路站）四区间（前临区间、临宝区间、宝宝区间、宝翻区间）的安装、装修工程及其他附属工程。

四区间均为两条单洞单线隧道，多数是盾构掘进形成，局部为矿山法挖掘或明挖法形成。中间有联络通道、泵房、风井。

为保证不间断供水，车站给水系统分别从车站两端市政给水管上分别引出1 根DN150进水管（互为备用）作为车站生活、生产与消防用水。一路自水表井后变为DN150至车站消防管网，另一路从水表井后分别引出两根水管，一路DN100给水管供车站生产生活用水和冷却冷冻循环补充用水，一路DN150至车站消防管网，进入车站的每根进水管上均设置倒流防止器，生活给水管与消防水管的引入管均设水表。

车站生产生活日用水量271.1m3，最高日用水量416.4m3。其中，人员用水定额为50L/ 人·班，最高日用水为2.5m3。消火栓用水量20L/s ，火灾延续时间为2 小时，局部喷淋强度不应低于6L/min ·平方米，持续喷水时间不低于0.5h 。水消防系统进入车站后经水泵加压后接入车站消火栓管网，消火栓系统成环状管网。
