Summary:Recently, tunnel construction is in the tendency of the big and long. So far, the method of mucking-out was general to use some dump trucks. This time, we are improved with a pit environment, rapid work, safety and saving labor of the tunnel construction. It developed “New muckong-out-system” which combined carrying out by endless conveyer belt, impact-roll-crasher with the temporary-moment-putting system use to some mucking vessels. This report introduces “New mucking-out-system” adopted in HAKKOUDA TUNNEL between HACHINOHE and SHIN-AOMORI at TOUHOKU SHINKANSEN.
