DCJ box culvert
Seismic resistance and water-tightness superior rubber ring joint method.
The DCJ box culvert can achieve high seismic and water-tight performance simply by inserting the "inlet" equipped with a two-layer structure special rubber ring into the "outlet." Additionally, it excels in workability as the internal joint work can be omitted. The special rubber ring features a two-layer structure, with a soft rubber base covered by hard rubber on the outside, which provides excellent followability, compression recovery, and abrasion resistance, maintaining high water-tight performance (0.06MPa) even during extraction due to seismic motion or after bending.
