Es-Hole - "Large Assembled Box-Type Manhole"
Assembled manhole combining box shape and circular shape.
The "S-Hole - Large Assembled Box-Type Manhole" can accommodate level 2 seismic motions as indicated in the "Guidelines and Explanations for Seismic Measures of Sewer Facilities" published by the Japan Sewer Association in most cases. To meet the needs of the site, we have standardized 13 sizes ranging from 1000mm x 1000mm to 3500mm x 1500mm. Since the components are assembled sequentially from the foundation block to the manhole cover, on-site construction is easy and does not require skilled workers. The foundation block is divided into two parts, making it easy to install inflow and outflow pipes. As a factory-produced product with quality control, there is no variation in quality or strength.
