大桥分两个场地同时施工,可隐约看见另一边的工地。
沿着吉首矮寨公路奇观,汽车爬上矮寨坡顶,今日,“解放思想在湖南”采访团来到吉茶高速矮寨悬索桥施工现场。只见挖土机不停作业,运输车来回穿梭,热闹非凡。矮寨悬索桥是吉首至茶洞高速公路跨越矮寨大峡谷的一座特大型桥梁,其主跨长度位居世界第三、亚洲第一。
矮寨悬索桥桥距吉首市区约20公里,跨越矮寨镇附近的山谷,德夯河流经谷底,桥面设计标高与地面高差达330米左右。桥型方案为钢桁加劲梁单跨悬索桥,全长1073.65m,悬索桥的主跨为1176m,总投资约7.2亿元,由湖南路桥集团承建。
“从去年10月28日开工至今,工程进展十分顺利,工程的建设得到了湘西州政府的大力支持,州委书记、州长多次来工地现场办公。”湖南路桥集团副总经理兼总工程师盛希说。
“大桥计划于2011年国庆前建成通车。对于建好这座亚洲第一大桥我们是有信心的,湖南路桥承建的南京长江第三大桥、南京长江第二大桥、岳阳洞庭湖大桥、宜昌长江公路大桥、安徽铜陵长江公路大桥等诸多项目荣获国家优质工程金奖、中国建筑工程‘鲁班奖’等”。”盛希告诉记者。
