Shorter construction period compared to on-site pouring! Capable of withstanding seismic motions at seismic design level 2!
The "MC Hole" is a modular rectangular manhole used for the maintenance and management of box culverts buried underground. The opening size of the installation pipe block can be adjusted to match the size of the installation pipe. The internal dimensions are standardized in ten sizes ranging from 1200×1200 to 3500×1500.
