Completion of the Ahmed Hamdi Tunnel beneath the Suez Canal in 1980 will establish the first tunnel to be constructed beneath an artificial waterway. It will also be the first such construction in which the deck and roadway are placed as the tunnel is being driven. The tunnel, which will have a bored length of 1640 M and an inside diameter of 10.4 M, is being driven through a mudstone which forms part of the shallupa ridge using a bade & theelen tunnelling shield. Behind the shield a 120 M long trailer incorporates belt conveyors for mucking-out operations and loading the concrete segments for erection in the tail of the shield. The main tunnel is being lined with reinforced concrete segmental rings each 1.2 M long and made up from 16 segments each weighing 3.25 tonnes. A feature of the lining system is the use of tunnel pak deformable inserts to relieve stresses between the precast concrete segments. A sencondary lining of the vehicle tunnel will be formed from a 2-4 mm plastics laminate attached with stainless steel bolts. (TRRL)
