Precast box culverts made of prestressed concrete according to the recommended specifications of JISA 5373 by the National Box Culvert Association.
By placing PC steel materials on the top and bottom plates, it is possible to reduce the thickness of the members, resulting in a lighter structure compared to RC box culverts. Standard sizes range from a width of 1.8m × height of 1.2m to a width of 5.0m × height of 2.5m.
A box culvert divided into a top slab component, side wall components, and a cast-in-place bottom slab component.
■ This is a box culvert that is divided into a top slab component, side wall components, and a cast-in-place bottom slab component. ■ After assembling the top slab and side wall components manufactured in the factory on-site, cast-in-place concrete is poured for the bottom slab. ■ Among large box culverts, it is suitable for large cross-sections ranging from 5.5 m to 10.0 m in width, and the components manufactured in two parts are integrated using mechanical joints and other methods.
Connecting the ancient and the modern, leaping into the future.
"Arch culvert" has an arch shape at the top and a box shape at the bottom, allowing the upper load to be transmitted as axial compressive force. The bending moment that occurs in the upper part and side walls of the member is significantly reduced compared to a box shape, enabling it to have high strength. Therefore, it is particularly effective against large soil cover and demonstrates economic efficiency. 【Features】 - Economic efficiency due to high strength - High water-tightness with rubber rings - Flexibility due to the elasticity of rubber rings - Economic efficiency through shortened construction periods For more details, please contact us or download the catalog.
Box culvert 1000×1000, recycling about 68,000 people’s daily urban waste in a 60m extension project.
This is a box culvert made using eco-cement derived from urban waste incineration ash and sewage sludge.

Just cover it.
By combining our unique oblique angle product manufacturing technology (patented), it has become possible to economically design and construct bridges and waterways that cross roads or rivers at an angle.
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.
Oblique Box Culvert "Parallel Box Culvert"
○NETIS: SK-090019-A Precast box culverts can be manufactured to match any intersection angle where rivers and roads or roads and roads intersect in three dimensions, making it difficult to approach directly. This technology allows for installation according to the effective width, enabling construction to be completed quickly with the shortest extension.
Box culvert construction method "Box Bearing Horizontal Pulling Method"
○NETIS: KT-990571-V This is a method for installing box culverts by lowering them from a designated entrance and pulling them along the rails using bearings (steel balls) and a winch or mobile machinery. It can be installed even in locations with obstacles or in narrow spaces.
Approximately 73% high green coverage! It suppresses the occurrence of unevenness and ensures walkability after construction.
The "Square Panel" is a concrete designed for green paving that supports a sustainable environment for plant growth. It was developed to protect plants during green paving. The cross-shaped protrusions effectively reduce pressure on the plants. Additionally, being made of concrete, it offers higher durability compared to plastic mat protective materials. 【Features】 ■ Reduces pressure on plants ■ Approximately 73% high green coverage rate ■ High durability ■ Shortened construction time ■ Suppresses unevenness *For more details, please refer to the PDF document or feel free to contact us.
