The junction at Nagyszombat Street required pipe jacking, in which we chose DN1200 steel sleeves with DN1000 SN10000 FRP pipes pulled inside.
The open-ditch constructions were secured with large-plate Rollbox shoring. Demolition of the pavement came as the first phase of works, performed with the tried-and-true asphalt deep-milling technique. Pipes to be laid consist of 170 metres of 70/105 and 134 metres of 60/90 FRP egg-shaped sections. The draughty weather preceding the works had a favourable effect on groundwater levels, making dewatering unnecessary.
