摘要： The proposed shield comprises in its frame a drive for advancing the shield along a path, a device for absorbing the thrust force from the drive and transmitting it to concrete in the process of its being pressed, a forming unit for forming the inner surface of a concrete lining, which, according to the invention, includes a former mounted coaxially in the shield frame and adapted to move by a drive along the shield longitudinal axis, and a supporting structure installed rearwardly of the former and adapted to move along the longitudinal axis of the concrete lining. The present invention will be most advantageously used in sand or unstable soil, where it makes possible to drive a tunnel practically without setting the earth surface and to preserve overground buildings situated close to the tunnel construction area. The present invention prevents the concrete lining from cracking in the process of its being formed.
