ABSTRACT:
A soil transporting vehicle for pressurized receiving and transporting of soil excavated by a shield machine. The vehicle includes a cylindrical soil container having a first opening and a second opening aligned along the longitudinal axis and being pressure-resistant. A soil conveying mechanism is arranged in the container adjacent to the opening for moving the soil axially. A chassis rotatably supports the container and a drive mechanism is provided for rotating the container about its axis from a soil introduction position where the openings are directed upwardly and a soil discharge position where the openings are directed downwardly. An inlet for introducing gas under pressure and a pressure regulating valve are provided on the soil container. The pressure is regulated to be substantially equal to that of the pressure compartment of the shield machine. A compressor is connected with the gas inlet. An opening and closing valve is arranged between the compressor and the gas inlet for admitting pressurized gas into the container to raise the pressure to be substantially equal to that of the pressure compartment of the shield machine before the soil is introduced into the soil container from the pressure compartment.
