Microtunnelling Update

On site at Walbottle , sinking of the 10m diameter shaft has restarted and is expected to reach final depth next week. A sheet piled coffer dam will be constructed at the north portal this week; this will provide protection for the workforce whilst the culvert is repaired. One of the buildings within the adjoining site (Dunelm) was demolished last week. At Crosby in Liverpool, the installation of glass fibre drainage pipes from manhole No 4 to manhole 5 is complete. A new shaft (manhole 6) has been more

HDD works at Rotherham

Ground conditions for the drill consisted mainly of stiff clay with approximately 1m of made ground (including old road surface) on either side of the crossing. An estimate of 2 shifts to carry out the works was adhered to with the actual drilling works including more

Update at Holton Heath

After encountering numerous technical difficulties during the past couple of weeks the DD140 drill rig has completed piloting under the extremely environmentally sensitive RAMSAR area of heath land between pit 17 to pit 12. We look forward to reaming and pulling pipe without quite so many problems! The D50 drill rig has completed reaming from pit 24 to pit 27 and is now preparing to pull pipe. With drilling still outstanding between pits 17 and 21, the end of a very difficult job is now just appearing on the horizon! more

Flooding at Newburn

The 10 1/2m diameter shaft has been constructed approx 6m below ground level (which is approx 3m from the crown of the culvert). Following heavy rain on 11th October the area upstream of the north portal has flooded (again). To minimise damage to the culvert, the shaft has been partially flooded to equalise the water pressure in the shaft and culvert. The flood water will be pumped from the upstream area over the weekend and shaft sinking towards the blockage in the culvert will then continue. more

The project involved the HDD installation of approximately 2000 metres of 50mm and 32mm MDPE harvesting pipe within the wall garden at Morley Retreat. HDD was the preferred option of installation as it vastly reduced the amount of excavation and reinstatement and caused less disruption. more
