Abstract

A perforating shield to open and at the same time cover tunnels continuously, in which using a blade shield that works without support, and whose perforating blades are supported next to one another in an axially displaceable manner on support frames transposable in pairs. The direction of the drilling and spreaders in the support position, a tunnel space is continuously opened and is provided by sections of a mixed concrete lining on site, introduced under pressure by a frontal formwork in a formwork space limited by the tail of the shield as an external formwork, and an advanced internal formwork, the front formwork being coupled through hydraulic cylinders, directed parallel to the axis of the tunnel, with the supporting frames of the shield, characterized in that, between the rear frame and the formwork trolley on one side, and between the rear support frame and one on on the other hand, hydraulic cylinders are provided in each case, the working phase of each of the groups of cylinders taking place independently of each other, as far as the advance of the knife-holder shield, of the filling of the annular space included between the formwork carriage and the follower blades as well as the advance in the dragging of the formwork trolley, and the follower blades having such a length that, in a working or damping space as large as possible, several concrete sections overlap.
