近日，由葛洲坝集团基础公司承建的西藏拉日铁路TJ6标段涵洞工程项目正式开工。
拉萨至日喀则铁路东起西藏自治区首府拉萨市，向西沿拉萨河而下，途经堆龙德庆县，曲水县后，溯雅鲁藏布江西上，经尼木、仁布县后折向西南，越吉琼垭口后，线路沿年楚河右岸下至本线终点站日喀则市，正线全长253.156公里。
该工程具有排洪、灌溉和立交功能，其中包含框架涵、盖板箱涵、圆管涵共175座。涵洞施工进度及质量直接影响着拉日铁路建设的进展，按照路基工程施工总体安排，指挥部采取了多个涵洞同时施工的方案，以确保线路范围内涵洞提前完工。目前，涵洞工程已作为建设单位开展的百日会战项目，为此，葛洲坝集团西藏拉日铁路指挥部，将在保工期、保质量、保环保、保水土、保安全前提下，着力做好各项涵洞施工任务。
