ハイブリッドマンホール協会 List of Products and Services

The method is a self-supporting manhole rehabilitation technique that can extend the lifespan of aging manholes. The construction is simplified and consists of stable materials produced in a factory. It can rehabilitate down to the invert, making the load-bearing capacity equivalent to that of a newly constructed manhole. Additionally, it includes measures to prevent liquefaction uplift and is compatible with seismic levels 1 and 2. Furthermore, it is designed so that vertical loads do not act on the aging vertical walls. 【Features】 ■ Simple construction ■ Load-bearing capacity equivalent to new construction ■ Measures to prevent liquefaction uplift are possible *For more details, please contact us or download the catalog.
