深圳地铁6号线施工突破亚洲第一难度

2017-12-27 11:57:18   央广网

央广网深圳12月27日消息(记者李强 通讯员陆满天)记者获悉,深圳市城市轨道交通6号线二期工程6111标主体工程民乐停车场出入线隧道线路大体呈东西走向,起点为翰梅区间,线路出区间后以R=300m曲率半径往西转,沿塘朗山西行1km,以R=260m曲率半径往东转接入民乐停车场线路。

项目负责人刘忠告诉记者,此标段TBM硬岩掘进机的小转弯半径只有260米,这个小半径在全亚洲都没有TBM施工先例的掘进。TBM理论上的转弯半径具备的能力是220米,通过理论上的模拟,基本是具备通过这个260米小半径的能力的,施工难度在亚洲属于第一。

刘忠解释说,TBM(硬岩掘进机)和盾构属于两大类,TBM主要是掘进硬岩用的,适用于30兆帕以上的岩石强度的地层的掘进。而盾构机主要针对软土、软岩,

记者了解,中铁五局电务城通公司承建的TBM区间主要依次穿越厦深高铁、地铁4号线、新彩通道、广深港高铁、侧穿牛咀水库等。中铁五局、中铁装备、中铁华隧联合研制的“韶山十六号”双护盾TBM,直径6.5米,全长130米,国产硬岩掘进机。结合深圳地铁6号线特殊的工程地质情况,中铁装备对TBM的刀盘刀具、驱动系统、尤其是260米小曲线转弯半径进行了针对性的优化设计。

中铁五局相关负责人告诉记者,TBM施工技术处于起步阶段,深圳地铁六号线停车场及出入线工程TBM隧道为通过7处断裂破碎带,个别破碎带可能水头高度较高(高度145m),施工时容易引起涌水涌砂现象、卡刀盘的情况,施工风险大。
