Middlewood Locks Project

The work consists of excavating a tunnel between secant piles and beneath an existing reinforced concrete slab. To restore the canal route beneath the newly built section of Manchester inner ring road as part of a large scale re-development project.

The tunnel was excavated using mini excavators with the material transferred to the surface using dumpers. The ground conditions vary between clay and rock and include the removal of an old lock section.

The work is being carried out for Volker Stevin, and includes shotcrete lining to the piles to form the permanent finish.
