ICOS INNOVATION IN MANCHESTER UNDERPASS

The article discusses the construction of an icos-designed underpass in Manchester. By incorporating 1072 M of mainly post-tensioned diaphragm walls, the construction method allowed three road bridges to be completed before excavation of the roadway beneath, so resulting in savings in construction costs. The diaphragm wall construction incorporated icos-flex retaining wall panels, icos-flex bridge abutment elements and icos retaining wall panels with reinforcement cages. Design and construction details of the underpass structure are described and the advantages of diaphragm wall construction are summarized as follows: land use losses are minimal; natural vegetation can be conserved; bridges can be constructed independently of underpass; construction cost economies can be achieved, and the alternative flyovers and ramps can be avoided in the interests of environmental quality. /TRRL/
