沪闵路地道桥是目前上海市境内最宽最深的铁路地道桥。首次在软土中采用地道桥不等高顶进技术施工,减少工程挖土和箱身工程量,加快施工进度;预留土堤增强被动土压力,减少基坑围护位移,将超宽超深的地道桥施工的安全风险降到最低。为确保基坑开挖和周围地下管线与铁路的安全,采取信息化施工。地道桥不等高顶进施工技术在沪闵路工程中取得成功。
Humin Road Road Bridge is the widest and deepest railway in Shanghai Bridge Road. For the first time, the construction of unequal height jacking technology for tunnel bridges is used in soft soil to reduce the excavation and boxing works and speed up the construction progress. The embankment is reserved for passive earth pressure and the displacement of foundation pit is reduced. Deep tunnel construction safety risks to a minimum. In order to ensure the safety of underground excavation and surrounding underground pipelines and railway, information construction should be taken. Road Bridge construction technology unequal elevation in Humin Lu project success.
