The cut ring part of the hand-dug shield is installed with a rotating large cutter with the same diameter as the shield, and the full section of the soil is excavated, which is called mechanical shield。It is suitable for all kinds of soil layers, especially for long tunnels in sandy soil layers that are easy to collapse, and can be continuously excavated。The soil produced by cutting the cutter head enters the soil tank through the reserved notch on the cutter head, lifts and flows into the funnel, and then carries the excavator through the conveyor belt。This kind of shield has the characteristics of good working environment, labor saving, time saving, labor saving, high efficiency, more follow-up equipment, difficult to correct when deviation occurs, and high cost。

The above share by Sichuan shield mortar manufacturers to share, if necessary, welcome to inquire。
