DCJ box culvert "K type/T type"

Can be used selectively according to the purpose! The internal joints can be omitted, making it excellent in terms of workability.

We would like to introduce our DCJ box culverts, "K type/T type." The "K type (flexible joint box culvert)" has flexibility in each product, ensuring sufficient water-tight performance. When ground conditions are good, it exhibits seismic performance due to the small amount of extraction and bending angle caused by seismic motion. The "T type (seismic-resistant joint box culvert)" addresses permanent deformation of liquefied ground due to lateral flow and permanent deformation of sloped ground in artificially modified areas by increasing the insertion length of the joint, satisfying the necessary extraction amount while ensuring sufficient water-tight performance. 【Features】 ■ Available in two types: "K type" and "T type," allowing for selection based on application ■ Capable of minimizing the extraction amount and bending angle occurring at each joint ■ Excellent followability, compressive recovery, and abrasion resistance ■ Maintains high water-tight performance (0.06MPa) even during extraction due to seismic motion or after bending *For more details, please refer to the PDF document or feel free to contact us.
