近日，由中交天和自主研发制造的17183-W1工号盾构机在成都市轨道交通13号线一期工程土建1工区瓦窑滩站~万家湾站区间左线顺利贯通。
瓦窑滩站~万家湾站区间左线全长1120.924米，区间最小曲线半径为600m，最大纵坡26‰。盾构段隧道覆土最大厚度19.85m，最小覆土厚度10m。地层主要为中密砂卵石，卵石颗粒的流塑性、改良性差，致使该地层的地表沉降不易控制，开挖面易失稳产生坍塌，对盾构施工技术有一定的要求。
面对诸多的风险源和复杂的地层地质，项目部统筹部署，合理安排专业技术人员，齐心协力、攻坚克难。技术指导服务期间，根据设备各项性能参数以及掘进地层，密切关注设备运行情况并提供优质技术服务，保障了设备高效率平稳掘进，为项目后续盾构施工作业积累了宝贵经验。
