Arrangement for feeding tunnel formwork with concrete

摘要

The tunnel formwork distributor has a swivel arm (6), arranged on rail running gear (1) and rotatable about an axis essentially coaxial to the tunnel axis, as well as a concrete line (20) which is guided concentrically through the swivel joint of the swivel arm and to which concrete is admitted from a remote concrete pump. The concrete line leads via a flexible hose piece (4') into a pipe piece (4) orientated parallel to the swivel arm. The tapered discharge socket (31) of the pipe piece (4) can be displaced radially in the direction of the tunnel formwork (25) and can be pressed against the injection socket (21) arranged there by the swivel arm (6) telescopically adjustable in its length. In order to permit adaptation of the tunnel formwork distributor to different tunnel diameters, the swivel arm (6) together with the motor-driven rotary mechanism (9) is fastened to a fixed supporting member (10) in a vertically adjustable manner. <IMAGE>
