特长隧道投料系统优化研究

Research on the optimum of feeding system of extra long tunnel

针对象山隧道2号斜井混凝土运输难题,介绍了采用混凝土竖直投料孔与斜井内混凝土溜槽下放2号斜井施工混凝土的具体方法和步骤,从而解决2号斜井长距离衬砌滞后而潜在安全风险的问题,为后续施工积累了经验。

Aiming at the difficulty of transporting concrete in inclined shaft No.2 in Xiangshan tunnel,the thesis introduced the specific way and procedures to lay down the concrete for the construction of inclined shaft No.2 by applying the concrete vertical batching hole and concrete chute laid in the inclined shaft,then solve the safe and risk problems hiding in the construction due to the potential risks caused by long-distance lining delay in inclined shaft No.2,which accumulate the experience for the coming rest construction.
