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 the DCJ box culverts 'K type/T type' that we handle. The "K type (box culvert with flexible joints)" has individual flexibility for each product, ensuring sufficient water tightness. When ground conditions are good, it exhibits seismic performance due to the small amount of extraction and bending angles caused by seismic motion. The "T type (box culvert with seismic joints)" satisfies the necessary extraction amount by increasing the insertion length of the joint section against permanent deformation of liquefied ground due to lateral flow and permanent deformation of sloped ground in artificially modified areas, ensuring sufficient water tightness. 【Features】 ■ Available in two types, "K type" and "T type," allowing for differentiation based on application ■ Capable of minimizing the extraction amount and bending angles occurring at each joint ■ Excellent followability, compressive recovery, and abrasion resistance ■ Maintains high water tightness (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.
