Ensure sufficient strength and durability! Capable of adapting to various conditions, it is possible to construct manholes suitable for the site!

The product is a box-shaped assembly manhole developed to improve workability. Since it only requires sequential assembly of precast components, it does not need skilled workers for complex rebar or formwork tasks. Because the top slab and bottom slab are integrated with the side walls, it has high rigidity against openings, and by using bolt connections, it ensures high integrity and water-tightness. 【Features】 ■ Easy to install ■ High integrity ■ Excellent site adaptability ■ Compatible with circular and rectangular openings ■ Stable quality
