PROJECT OVERVIEW
Murton Gap Phase 3 project, required the construction of a sustainable drainage system (SuDS) corridor to intercept and attenuate surface water draining from Murton Gap and to discharge it to the existing surface water sewer that drains to Marden Quarry.
DESCRIPTION OF WORKS
From a 2.4 diameter caisson drive shaft 35 metres of DN450 Tracy Concrete jacking pipe was installed under a 15″ CICL and a 12″ CICL water main to a 1.75 metre square trench sheeted reception shaft.
During pipe installation the ground conditions changed and layers of sandstone were encountered, this required the addition of high-pressure water to be introduced.
CLIENTS REMARKS
