A modular manhole combining rectangular and circular shapes.
■ 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 Sewerage Association in most cases. ■ To meet the needs of the site, we have standardized 13 sizes ranging from 1000mm × 1000mm to 3500mm × 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 section 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.
