METRO WORKS IN ANTWERP, BELGIUM: USE OF A 6.50 M DIAMETER BENTONITE SHIELD FOR THE TUNNELS AND PIPE-JACKING FOR THE STATIONS

Metro works in Antwerp were started in January, 1970; the first part, carried out by cut and cover methods, caused considerable traffic congestion and generally disturbed the business area. Pressure by the public led the national ministry of transport (which finances the entire works) to accept that the second part should be undertaken by underground methods to avoid any disruption. Previous tenders were withdrawn and a new investigation was ordered. In the revised tender-documents the use of a 6.5 M diameter bentonite shield was specified to avoid compressed-air working and to reduce surface settlement. Details of the shield are presented, together with technical information on the overall project. A method of pipe-jacking for the roof slab of tunnels is described for use where the tunnel is shallow and a shield cannot be used. The covering abstract for the proceedings is IRRD abstract no 252594.
