郑州轨道5号线土建08标 经开第三大街站监测方案
1. 工程概况
概述
轨道交通5号线车站位于东路与第三大街交界处，与远期13号线地下一层通道换乘，站点周边有河南和胜工程机械有限公司、河南龙工机械制造有限公司、惠安手外科医院、天明公园等。
轨道交通5号线经开第三大街站有效中心里程为DK22+，设计起点里程为DK22+，设计终点里程为DK22+，。
、结构形式及施工方法
经开第三大街站为地下两层岛式站台车站，为地铁5号线和13号线的换乘车站，换乘方式拟为通道换乘，远期13号线区间隧道下穿五号线车站。，，站台宽14m，本站共设4个出入口，2个风亭组；~；~。周边空地较多，采用明挖法施工，开挖面积约为16455m2。车站主体采用钢筋混凝土箱型结构，车站主体设全体外包防水层；车站主体基坑围护结构采用钻孔灌注桩+内支撑的支护形式。，，。开挖范围的土层主要为：细砂、粘质粉土、粉砂；基底处的土层主要为细砂、粉砂层。
