Oblique Large Box Culvert "FA Box"

Oblique Large Box Culvert "FA Box"

Large box culvert 'FA Box' with improved constructability and cost-effectiveness by combining slabs.

The FA box is a construction method that combines precast components divided into three parts with cast-in-place concrete to create a large-section box. - The product's structure consists of a combination of slabs, resulting in low manufacturing costs! - By using a separated structure (segmentation) for the top slab and side walls, it has become possible to standardize responses to sites with slopes. - The connection is made easy by using loop joints to integrate with cast-in-place concrete!

FA box large box culvert can accommodate angled configurations.

FA box large box culvert can accommodate angled configurations.

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.

Oblique Large Box Culvert "FA Box"

Oblique Large Box Culvert "FA Box"

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).
