Independent Type Protective Fence Foundation PreGuard II (PG Foundation)

Independent Type Protective Fence Foundation PreGuard II (PG Foundation)

This is a concrete product whose safety has been confirmed through static load testing with actual objects.

The Preguard II (PG Foundation) is a concrete product with a cross-section shaped like an inverted T and a length of 2 meters. This product is designed to function as a unified protective fence foundation by connecting 4 to 10 units in the direction of road extension (longitudinally). The friction resistance generated on the bottom surface of the product is treated as a discrete-type spring, and the bending moments and shear forces are calculated as a beam on a finite-length elastic floor, ensuring through stress calculations that the product does not experience bending or shear failure. 【Features】 ○ Excellent workability and environmental compatibility ○ Lightweight, allowing for construction with small machinery ○ Superior economic efficiency and safety ○ Performance verified through static full-scale experiments ○ NETIS registration NO. SK-060003-V For more details, please contact us or download the catalog.

Shallowly buried protective fence foundation "Intersection-use flexible R continuous foundation"

Shallowly buried protective fence foundation "Intersection-use flexible R continuous foundation"

A precast continuous foundation that achieves early traffic regulation release, optimal for intersections with many buried objects, with pillar embedment depth of 250 mm and foundation height of 300 mm.

The "Intersection Use Free R Continuous Foundation" has a lower foundation height (300 mm) compared to the conventional Free R Continuous Foundation, allowing for the installation of protective fences in sites where only shallow embedding is possible. The foundation height is 300 mm, and it corresponds to the post installation depth of 250 mm specified in the protective fence installation standards and vehicle protective fence standard specifications. With a continuous foundation extension of 5 m, safety during collisions is ensured, and the installation of vehicle stops (bollards) is also possible. 【Features】 ■ Compatible with a post installation depth of 250 mm, foundation height is 300 mm ■ Can be installed with a short extension (minimum continuous required extension of 5 m) ■ Can accommodate a minimum radius of 5R ■ Due to the increased foundation width, the top can be lowered by one step on the sidewalk, and interlocking can be placed over it to avoid visual obstruction ■ Considering the installation of vehicle stops (bollards), the post spacing can be adjusted in increments of 0.25 m from 1 m to 2 m ■ Available nationwide in Japan *For more details, please refer to the PDF document or feel free to contact us.
