jacking loads IVlW jacking fpmccann pipes FP McCann jacking pipes are designed to meet the requirements of British Standard 5911 Part 1 and European Standard BSEN 1916. The Maximum Jacking Force (Fjmax *) which can be applied to a pipe is determined by the pipe strength, the configuration of the thrust ring and the tunnel alignment i.e. the angular deflection between pipes. The maximum load decreases as angular deflections occur during jacking. Should deflection exceed that which can be accommodated by the packer, the maximum load decreases significantly. The figures below are for guidance...
