摘要
文章依托郑州地铁3号线工程顺城街站—东大街站区间工程,通过采用短钢套筒始发施工技术,不仅解决了端头加固质量差的难题,还有效控制了盾构始发段近距离上跨既有2号线隧道结构变形的难题,取得了良好效果,相应施工经验可为类似工程提供借鉴与参考。
Taking the running tunnel between Shuncheng Street station and Dongdajie station of Zhengzhou metro Line 3 as an example,by using the short steel sleeve launching construction technology,not only does it solve the problem of poor quality of end reinforcement,but also effectively controls the problem of deformation of the tunnel structure that crosses above the existing line 2 at a short distance from the launching section of the shield.Good results have been achieved.The corresponding construction experience can be used for reference for similar projects.
