高山滑雪赛道碎石土无动力运输施工技术研究

Research on Construction Technology of Unpowered Transportation of Gravel on Alpine Ski Course

考虑到国家高山滑雪中心高山雪道施工山体坡度极大等工程实际情况,采用传统汽运或其他动力运输系统将大大提高运输成本,且施工工艺复杂、不便实施。在施工过程中首次提出无动力溜槽碎石土运输系统,详细介绍了该系统的设计、修建与使用技术。从施工过程中的土石运输方式出发,研究溜槽运输,探讨高陡路线的快速、高效、节能运输方式。工程实践表明,改技术取得了良好的工程和经济效益。

In consideration of the actual situation of the National Alpine Skiing Center,such as the great slope of the mountain construction,the use of traditional automobile or other power transportation system will greatly increase the transportation cost,and the construction process is complex and inconvenient to implement.In the process of construction,the gravel soil transportation system without power chute is put forward for the first time.The design,construction and application technology of the system are introduced in detail.Starting from the transportation mode of earth and stone in the construction process,this paper studies the chute transportation and discusses the fast,efficient and energy-saving transportation mode of high and steep routes.Engineering practice shows that the technology has achieved good engineering and economic benefits.
