The manhole box is a 4 sided box used to construct pre-cast concrete manhole chambers, small chambers and small tanks. It delivers time and labour cost advantages over hydraulic manhole brace and trench sheets. Effective down to 5.50m, provided ground pressure does not exceed the Permissible SWL of 34.1 kN / m2 for Std and 44 kN / m2 for the BV100. Generation provide a design support to ensure the correct use. Manhole Braces are the alternative if it exceeds the SWL and if cross services are an issue on-site.
