A two year, 1.75 million pound development scheme is being financed by the Yorkshire Water Authority in an attempt to find an efficient microtunnelling system. The project described utilises a Soltau RVS 250A microtunneller marketed by Decon Engineering and jacking pipes being developed by ARC Pipes. The 300,000 pound system is operated from a 6m long container placed over the access shaft. The jointed cutting head is steered by laser and rectified by hydraulic rams. Spoil is removed by the auger string and carried backwards to the bottom of the access shaft where it is hoisted out. The new sewer pipes are 1.5m long with a 600mm internal diameter and incorporate a newly designed sealing system. Progress has been 10-14m a day through boulder clay with stones and cobbles and it is planned to try out the microtunneller progressively through all Yorkshire's different ground conditions. (TRRL)
