长输管道施工中斜缆索物料运送技术

山区长输管道所经地形高低起伏,沟壑纵横,河流交错,施工机械难以通行,施工设备和材料的运输成为一大难题.在太原钢铁集团公司尖山铁精矿管道工程施工中,由于输送铁矿浆的特殊性,要求管道敷设坡度不大于10%,管道在汾河二库地段多处穿越隧道,本文结合隧道管道的运送介绍了斜缆索的结构形式、结构件的选择和安装操作技术要点等方面内容,解决了山区管道施工物料运输问题,节约了人力物力,加快了工程建设进度,取得了很好的经济效益.

Technique of Material-delivering by Inclining Rope Crossover in Long-distance Transporting Pipeline Construction

At mountain areas long-distance transporting pipeline passes through the area where landform fluctuate,gully intervein,river intersect. Construction machinery passes very difficultly, so that the transportation of construction equipment and material becomes one of the tough problems. In the construction of the pipeline for Jianshan mineral fines of Taiyuan Steel Group Company,the design requires that pipelining gradient is no more than 10%. The pipeline passes through tunnel in places at the second Fenhe River reservoir area. According to the pipe delivery used in tunnel, this article introduces the following contents, such as the formation of inclining rope structure, selection of the structural members, installation and operation technique points and so on. The method solved the problem of material-delivering in the construction of the pipeline at mountain areas, saved manpower and material resources, speeded up construction progress, obtained very Rood economic benefits.
