深圳地铁3号线西延线工程3151标益田站 地下连续墙钢筋笼吊装方案

2 工程概况

2.1 工程简介

益田站站是深圳地铁3号线西延线工程第1站。车站主体围护结构采用800mm厚地下连续墙，全为钢筋笼混凝土结构，共180幅，其中“—”型168幅，“L”型6幅，“Z”型4幅、“T”型2幅。地连墙深度最大为24.8 m、最小为21.3m，标准幅宽为5m、6m等，并有少量5.2m及6.25m幅宽类型，幅间采用工字钢接头。

2.2 气象条件

深圳市的气候属亚热带季风气候，热量丰富，日照时间长，雨量充沛。气候和降雨量随冬、夏季风的转换而变化。

风向频率：深圳地区常年盛行南东东风，风向频率为17%；北北东风，风向频率为14%；其次为东风，风向频率11％；随季节和地形不同，风向频率也不同。

风速：年平均风速为2.5m/s；极端最大风速为40m/s（为南或南南东向台风）。 降雨量：深圳地区降水量丰沛，地区差异明显。多年平均年降雨量为1933.3mm，雨季（5～9月）平均降雨量为1516.1mm。年降水日数为144.7天，连续最长降水日数20天。

暴雨及台风为灾害性气候，对钢筋笼吊装工程施工有一定不利影响。

2.3 主要工程数量

本车站地下连续墙钢筋笼吊装主要工程数量见表1。
