Renewal Method for Mats and Ditches | Steel Lid Reduction Method Lifthas
A renewal method that utilizes existing gutters and manholes as they are and can be constructed using only general tools.
The construction can be completed in just a few hours, allowing for a quick project timeline and immediate traffic reopening. Additionally, it enables significant weight reduction and functional improvements of the lid while simultaneously performing repairs, thus solving various issues on-site. Structure of Liftus This method involves setting a frame that is slightly smaller than the existing lid like a "nested" structure and filling the gap with grout material (non-shrink mortar) to secure the lid support and the new frame. Both the lid and the frame are made of high-tensile steel, which has a higher strength than conventional steel. The grating is lightweight while still satisfying the conventional strength standards.
