Box culvert with seismic-resistant rubber ring
The "DCJ Box Culvert" is a box culvert that ensures high seismic and watertight performance simply by inserting the inlet with a special rubber ring featuring a two-layer structure into the outlet. It allows for the omission of internal joints, resulting in excellent workability. Additionally, by absorbing ground displacement at each joint of the product, it reduces the stress generated in the structure and minimizes the amount of pull-out and bending angles at each joint. 【Features】 - Available in two types: K-type and T-type, allowing for differentiation based on application. - The special rubber ring excels in followability, compression recovery, and wear resistance, maintaining high watertight performance (0.06 MPa) even during pull-out due to seismic motion or after bending. - Certified product by the Japan Precast Concrete Products Technology Association. *For more details, please download the PDF or feel free to contact us.
