Assembly manhole for large diameter pipelines

Assembly manhole for large diameter pipelines

This is an assembly manhole developed for large-diameter pipelines with the aim of improving workability.

By adopting the CGP method, we have achieved a reduction in construction time through pin guiding and pin joining. The use of resin pins provides excellent elasticity and high strength against shear. The durability is permanent. With the adoption of water-swelling elastic sealing material, waterproofing measures can be completed simply by applying the sealing material to the joint slope with a gun. For more details, please contact us or download the catalog.

Sewer products Manhole K-TIK hole

Sewer products Manhole K-TIK hole

The K-TIK Hall is an assembled manhole certified and registered as Type II equipment by the Japan Sewage Works Association.

The joints use K-TIK seals, allowing for construction even in rainy weather, so the work process is not affected by the weather. The steps are made with integrated molding for sloped and vertical wall blocks, while the bottom blocks are of the bolt-fixed type, eliminating any concern about them falling out. The adoption of a monolithic bottom block design ensures there is no leakage at the lowest point. We use a flexible joint called "K-TIK Boot" that can be installed with a single touch. To prevent displacement due to uneven loads during sheet pile extraction, plates for block connection are used.

Construction materials, water supply and drainage, assembled manhole.

Construction materials, water supply and drainage, assembled manhole.

Leave the sale of manhole covers and replacement work through machine construction to us.

For the installation work of manhole covers, we recommend the Parabola method using a parabolic cutter. The Parabola method is a new technique that cuts the asphalt surface into a circular spherical shape for the replacement and repair of manhole iron covers. It finishes the work neatly and accurately. The parabolic cross-section has excellent adhesion and there is no wobbling after construction.
