NEW UNDERGROUND LINING - THE COMPOSITE SEGMENT: CONCRETE/DUCTILE CAST IRON

UN REVETEMENT SOUTERRAIN DE CONCEPTION NOUVELLE - LE VOUSSOIR MIXTE: BETON-FONTE DUCTILE

In connection with studies conducted for the Channel Tunnel, different types of precast lining were compared among them reinforced concrete segments and cast iron segments. Studies led to the development of a composite segment (concrete/ductile cast iron). Its manufacture is described together with its characteristics, functions of the concrete, tests carried out (loading, adhesion of cast iron bars sunk in concrete, etc). The authors propose a design method and describe the various possibilities of use of composite segments, installation tolerances. A comparison is made between the composite segment and the reinforced concrete segment from the economic point of view. (TRRL)
