Abstract:

With the rapid advancement of tunnel-boring machines, driving operation has recently been carried out with a higher level of speed and efficiency. However, in the case of long tunnels, a rapid transportation system that supports speedy driving is indispensable. It is also important, after carrying out accurate monitoring of a flow of work involved in tunnel driving, from workers' going-in and -out of the tunnel, construction equipment and materials supply, to spoil removal operation, to maintain proper control of the entire work process to achieve the smooth progress of tunnel driving with enhanced safety. In order to achieve this, and to ensure the safety of workers during the process of rapid transportation, automating tunnel haulage operation and thus minimizing the number of operators and workers inside the tunnel is a viable strategy. A system developed to fulfill these requirements comprises more than one unattended train that travel back and forth inside the tunnel and a train operation control device that continuously monitors on-going operations of the trains to ensure safety. This paper gives an overview of the ""automatic transportation system intended for long tunnels"" and reports the application of this system to Doushi Headrace (Hayato section) construction.
