1 Tunnel Overview and Mechanical Equipment 1 1 Tunnel Overview: The construction tunnel is a single-track railway tunnel with a total length of 4 767m and two tunnels with an exit of 2 344m and an inlet of 2 4 33m. The exit is the main test site. About 1km away from the door, a inclined hole of 30m was drilled. During the test, 195m of tunnels were being drilled, and full-face deep-hole blasting was used to mechanize the ballastless track transportation. Using a single push-type send
