Box culvert installation method Box bearing lateral pulling method

Box culvert installation method Box bearing horizontal pulling method "NETIS" registered

【Features】 ○ Smooth installation work can be carried out even in narrow construction yards. ○ The loading operation (crane work) and installation work (horizontal pulling work) can be separated, allowing for rapid construction. ○ The excavation width is smaller compared to conventional methods. ○ Once the cover plates are installed, work can be conducted underground, allowing traffic above to remain open. ○ There is no need for the crane to move during installation, allowing for placement at a single lowering location. ○ Ideal for construction in densely populated residential areas, under busy roads, and for crossings under bridges and railways. ○ Installation work is possible even in areas with overhead obstacles such as elevated bridges and power lines. ○ The friction between the box culvert and the foundation is low, reducing the vertical PC tension to below 50%. ○ Construction is possible with a longitudinal slope of up to 10%. *For more details, please inquire.

RPCA-DCJ box culvert

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.

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.

Chloroguard: Concrete Resistant to Deterioration from Salt Damage and Freezing Damage

Ideal for coastal areas and cold regions! Extend the lifespan of structures and reduce lifecycle costs!

"Chloroguard" is a concrete that is resistant to deterioration caused by salt damage and freeze damage. Precast products made with this product have excellent resistance to chloride ion penetration compared to products that do not use it, due to densification and the fixation of chloride ions, resulting in high salt damage resistance. Additionally, it excels in compressive strength, drying shrinkage characteristics, and resistance to freeze-thaw cycles, contributing to the longevity of structures. It protects structures from salt damage in coastal areas and regions where freeze prevention agents are applied. [Features] - Suppresses the progression of salt damage - Exhibits high compressive strength - Minimal drying shrinkage, reducing cracking - High freeze damage resistance suppresses deterioration - Prevents deterioration of steel materials by reducing chloride ion concentration This product has been registered with NETIS (CG-150009-A). *For more details, please refer to the PDF materials or feel free to contact us.
