We offer sizes ranging from 240mm to 10m, and we can propose earthquake resistance, functionality, and various construction methods according to your needs.
Our Calvert products are widely used in various projects such as urban sewers, agricultural drainage ditches, underground passages, and culverts for road crossings, utilizing environmental creation technology that supports urban functions.
This is a large box culvert that can accommodate angled configurations. It can handle an internal width of 5 to 12 meters, an internal height of 2 to 7 meters, and angles from 60° to 90° (in 5° increments).
The FA box is a construction method that combines precast components divided into three sections with cast-in-place concrete to create a large cross-section box. By segmenting the top slab and side walls, it becomes easier to accommodate "slant angles." The precast components are designed as a slab structure, while the bottom slab is cast on-site, resulting in a cost-effective large box. The use of loop joints allows for easy integration of the precast components, facilitating construction and shortening the construction period. Additionally, using PCA wing walls can further reduce the construction time.
Our original box culvert
■It can be installed in a top-down manner. ■Standard sizes are from 0.3m wide × 0.3m high to 0.6m wide × 0.6m high. For specifications other than the above, please consult us.
A box culvert equipped with a special rubber ring at the joint section to enhance 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 non-liquefiable, non-inclined ground conditions. 【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.
A box culvert divided into a top slab component and a bottom slab component.
■Among large box culverts, it is applied to relatively small cross-sections ranging from 4.0m to 6.0m in width. ■The components manufactured in upper and lower sections are integrated using mechanical joints and other methods.
A box culvert composed entirely of precast components, divided into a top slab member, side wall members, and a bottom slab member.
■ It is applicable to large box culverts with a cross-section width ranging from 5.5 m to 10.0 m. ■ The components manufactured in sections are integrated using mechanical joints and other methods.
PC box culverts that contribute to the labor-saving and speeding up of construction.
PC box culverts are designed with prestressed concrete structures (using PC steel bars for transverse reinforcement) for the top slab and bottom slab, which are directly affected by variable loads (live loads). This design eliminates the occurrence of cracks, a common drawback of reinforced concrete products, and also enhances resistance to impact and repeated loads.

![[Construction Example] River Improvement Work: Installation of Box Culvert](https://image.www.ipros.com/public/product/image/050/2000693409/IPROS43394985905806343025.png?w=280&h=280)
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 of installing a new box culvert next to a river (drainage) that is overflowing. The total height of the box culvert to be installed, including the crushed stone foundation height and the concrete base 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, a trench width of W=4.6m must be secured. 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 document or feel free to contact us.

A large angled box culvert that enables shortening of construction time and labor reduction!
The "FA Box" is a construction method for building large-section boxes that utilize a combination of three-part PCa components and cast-in-place concrete. By adopting a separated structure (segmentation) for the top slab and side walls, it has become possible to standardize responses to sites with angled configurations. Additionally, at the joints between components, in addition to water-stopping gaskets, the application of waterproof materials and the use of waterproof sheets are also employed to enhance the water-stopping effect. This product has been registered with NETIS (QS-110006-VR).
Two types available! Box culvert with flexible and earthquake-resistant rubber ring joints.
This product is a box culvert equipped with special rubber rings on each individual block, providing flexibility, seismic resistance, and water-tightness. There are two types, IB10 and IB50, depending on the size of the protrusion, allowing for differentiation based on required performance. The structure incorporates IB rubber rings at the inlet of the box culvert, and installation is the same as standard boxes. 【Features】 <IB10 Type (10mm Protrusion)> ■ Does not change the joint shape or dimensions of the standard box, which has a proven track record ■ Structurally reliable and economically advantageous ■ Applicable range / nominal dimensions □1000×800 to □4000×2500 ■ Obtained construction technology review certification from the Public Interest Incorporated Foundation, Sewerage New Technology Promotion Organization *For more details, please refer to the PDF materials or feel free to contact us.
With a track record of 2,000 km nationwide and overwhelming support, flexible performance is added to the pressure pipes!
The "flexible pressure pipe" can respond to Level 2 seismic motions as described in the "Guidelines and Explanations for Seismic Measures in Sewer Facilities" by allowing individual joints to move. By absorbing ground displacement at each joint, the stress generated in the longitudinal direction of the pressure pipe can be reduced, and the amount of pull-out and bending angles at each joint can be minimized. Additionally, we also handle seismic-resistant manhole joints for pressure pipes called "Round Press." 【Features】 ■ High strength ■ Easy and convenient installation ■ Compatible with Level 1 and 2 seismic motions ■ Excellent water tightness *For more details, please refer to the PDF materials or feel free to contact us.
