大坡度施工斜井有轨运输与皮带机运输的比选

Analysis on Selection of Rail Transport and Belt Conveyor Transport in Slope Construction

受到地质条件、施工组织、施工工期、成本投资等因素的影响,深埋长大隧洞按照“长隧短打”的思路,在越来越多的隧洞工程中得到运用,而大坡度长斜井渣料提升运输技术,是深埋隧洞施工建设长期研究的关键技术之一。以滇中引水工程香炉山2号施工斜井为工程实例,通过对皮带机运输和绞车有轨运输能力的对比分析,提出经验总结和个人见解。

Affected by geological conditions,construction organization,construction period,cost investment and other factors,deep-buried long and long tunnels are applied in more and more tunnel projects according to the idea of"multi-section short tunnel construction for long tunnels".Slag lifting and transportation technology of long inclined shaft with large slope is one of the key technologies for long-term research on construction and construction of deep tunnel.Taking Xianglushan No.2 inclined shaft of water diversion project in Yunnan as an example,this paper makes a comparative analysis on the belt conveyance capacity and the rail transport capacity of winches,and puts forward experience summary and personal opinions.
