基于RS485总线的隧道机车控制器设计

针对隧道机车工作环境复杂等特点,出于对人身和设备安全的考虑,对机车控制器进行基于RS485总线的硬件和软件设计,这种分布式控制系统已经应用到现场隧道机车中,系统运行稳定、可靠,操作简单,起到安全保护的作用,达到了设计的目标。

隧道出碴系统的比较

隧道所采用的出碴方法对隧道进度有着决定性影响。虽然大直径隧道的设备的选择范围明显增加,但是它常常是由隧道尺寸所特定的。工程技术记者西蒙·沃尔克(Simon Walker)对其设备选择发表了一些看法。

Researches on the key technology and equipment for rapid construction of long tunnels with large section

Excavation and lining are two main important tasks in tunnel construction. Conventional sequential operations may not be appropriate due to time limit for a project and the high cost of construction. The authors developed a new mode of tunnel construction that excavation and lining can be operated simultaneously. The new mode of tunnel construction has been successfully applied to Dahuofang Water Conveyance Project in Liaoning Province. This paper makes a comparison of Main Beam TBMs and Double Shield TBMs used in Dahuofang Water Conveyance Project, and the features of Full-ring Inner-through Lining Shutter Jumbo which solves the problem of interference between excavation and lining.

德国新型隧道维修内燃机车

为了保证高速铁路隧道结构稳定性和安全使用，要对隧道进行定期检修。为此，专门开发了一种以特殊机械技术装备为基础的铁路隧道维修机车（TIF）。文中介绍了这种机车的结构、原理和主要技术参数。
