高强度、大坡度隧洞施工运输系统设计

The Transportation System Design of Constructing the High-intensity and Large-slope Tunnel

在山西大水网工程建设项目中,输水隧洞工程项目占有相当大的比例,且有许多隧洞因地理位置及输水线路等因素造成其埋深较大,坡度很大。由此带来一些新的隧洞施工难题需要面对和克服。文中以实际工程为依托,对在工程实施中遇到的高强度、大坡度隧洞施工运输难题,有针对性地进行分析研究,在确保安全施工的前提下,设计制定了适宜的渣料装、运、卸方案及洞内所需施工材料的运输方案,对高强度、大坡度隧洞施工运输方案提出了建设性的意见。

In the construction works of the Shanxi Large Water Diversion Network Project, the quantity of water diversion tunnel projects constitutes a large proportion in the whole project, and because of problems of geological and water diversion line positions, many tunnels have the features of deep buried depth and large slope, and as a result of all these, a set of new construction puzzles is brought and must be overcomed. On the basis of an actual project, the construction transportation puzzles for constructing a high-intensity and large-slope tunnel that are encountered in many projects are purposefully analyzed and studied. Under the premise condition to ensure the construction safety, the paper draws up a proper plan to load, transport, unload the rock fragment and materials needed in the process to construct the tunnel, and puts forward some suggestions on construction transportalion plan for these kinds of tunnels.
