Manhole Boxes

3D Model

MGF Manhole Boxes are simple to assemble, robust, four sided excavation support systems that are designed to be installed by an excavator utilising the dig and push, or excavate and lower in place techniques. They are normally used for installing precast concrete manhole rings, small chambers or tanks, where ground movement is not critical. The systems comprise of base and top panels, which are propped off from each other using telescopic steel struts. Depths of up to 5.8m are possible when using 2 additional top units. Manhole Boxes are generally provided in a square configuration, with panel lengths of up to 5.2m available, suitable for use with the full range of PCC manhole rings.
