Hat Ring Method for Suppressing Manhole Uplift during Earthquakes
Always non-weighted construction method! Since no special construction is performed, it can be done easily and in a short time. [Looking for sales partners]
The "Hattling Method" involves installing buoyancy suppression blocks at a standard depth of 1.0m, utilizing the weight of the blocks and the weight of the backfill soil (crushed stone) on top of the blocks to suppress the uplift of manholes only when liquefaction occurs. This method can be applied not only to existing manholes in urban areas, which are significantly affected by uplift, but also to newly installed manholes. It can be constructed easily and at a low cost without affecting the manhole itself. 【Features】 ■ Can be installed on both existing and new manholes ■ Does not affect the manhole ■ No increase in inertial forces due to seismic motion ■ Can be constructed easily and in a short time *For more details, please refer to the PDF materials or feel free to contact us. 【Looking for Sales Partners】 We will sell your products!
