Shore Hire’s 3M manhole boxes extend the capability of our trench box range with additional features to accommodate adjoining service trenches. The manhole box allows for wider trench support specifically at the manhole site without widening the entire trench.
Panel gaps are provided on two faces to accommodate trench runs into the manhole box, with trench sheets able to be added to close off ends.
Transport to site can be in knocked-down form with assembly possible in only a short time to suit the customer’s needs, either in a pre-existing trench or, in loose and sandy soils, via a progressive dig and push method. This allows rapid construction of manholes, chambers and interceptors, with the all-steel construction providing a robust trench shield.
A full range of working at height safety equipment is available as the perfect complement to all Shore Hire boxes and trench sheet systems, to ensure the utmost safety at all times.
Manhole boxes enable wider trench support at the manhole site while accommodating adjoining service trenches. Panel gaps on either end can be easily shored using trench sheets. They allow rapid construction and installation of precast concrete manholes, interceptors, small chambers or tanks.
The Shore 3M Manhole Box is designed to safely and effectively support trenches up to any depth, provided that the working load limit of 50kPa is not exceeded.
The Shore 3M Manhole Box can be delivered standalone or as as part of our comprehensive full-service solution. This includes:
