　　3月15日上午，伴随着成槽机的阵阵轰鸣声，水电八局承建的长沙地铁4号线二标段砂子塘站一期主体围护结构首幅地连墙顺利开槽。至此，砂子塘站主体围护结构一期工程正式开工。
　　砂子塘站为地下三层三跨岛式车站，外包尺寸长169.6米，标准段基坑宽度22.9米，采用半盖挖法施工。车站位于黄土岭路与韶山中路交汇路口处，与远期地铁7号线呈“L”型换乘，所处地势复杂，施工难度大，根据交通疏方案把车站主体施工分为两期施工，主体围护结构采用1000毫米厚地下连续墙，一期施工17幅，二期施工59幅，共计76幅。
　　一期施工范围内的地连墙施工完成后，便可进行该区域内的路面盖板施工，进而恢复交通路面，随后完成二期交通疏解，进入二期施工阶段。
