DCJ box culvert "K type/T type"

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.

DCJ Box Culvert "Seismic Resistant Joint Box Culvert"

DCJ Box Culvert "Seismic Resistant Joint Box Culvert"

A box culvert equipped with a special rubber ring at the joint section to provide seismic performance.

■There are two types, K-type and T-type, depending on the required performance. 【K-type】 It has water-tightness that can withstand a water pressure of 0.06 MPa under level 2 seismic motion in a non-liquefied, non-inclined ground condition. 【T-type】 It has water-tightness that can withstand a water pressure of 0.06 MPa under level 2 seismic motion. ■By absorbing ground displacement at each joint of the product, it is possible to reduce the stress generated in the structure and minimize the amount of pull-out and bending angle occurring at each joint. ■The special rubber ring has a two-layer structure, with soft rubber covered by hard rubber on the outside, providing excellent followability, compression recovery, and wear resistance. ■High water-tightness can be achieved with the special rubber ring alone, eliminating the need for internal joint work.

[Construction Case] River Improvement Work - Installation of Box Culvert

[Construction Case] River Improvement Work - Installation of Box Culvert

Clear in terms of strength! Using "GPL soil retention" and "GPL long support" in the rainwater box culvert installation work!

We would like to introduce a construction case where a box culvert was newly installed next to a river (drainage) that was overflowing. The total height of the box culvert to be installed, including the crushed stone foundation height and the base concrete height, is approximately 2,500mm. Since the top of the box culvert will be at almost the same height as the ground level (GL), the cut beam of the GPL retaining wall must be above the GL, and the opening height must be secured to be at least 2,500mm. Additionally, the excavation width must be secured to W=4.6m. The challenge was to meet these three points, but under the current site conditions, we were able to meet both product and strength requirements with the "GPL retaining wall." 【Equipment Used】 ■ Aluminum sheet piles ■ GPL retaining wall ■ Hydraulic four-sided beams ■ Fence *For more details, please refer to the PDF materials or feel free to contact us.
