Temporary protective fence with a waiting type corresponding to the rockfall countermeasure manual.
The "QT Fence" is a temporary protective fence that can be used for emergency measures and temporary measures after a disaster. We conducted a free-fall weight drop test on a real specimen to confirm its rockfall capture performance. The applicable range for accumulated soil is approximately 1 meter. The foundation is constructed using "single pipes" primarily for on-site use, eliminating the need for large-scale foundations, allowing it to be installed not only along roads but also on slopes. ■ Waiting-type temporary protective fence ■ Complies with rockfall countermeasure guidelines *For more details, please download the PDF or feel free to contact us.

basic information
QT fences are composed of posts, diamond wire mesh, wire ropes, cushioning fittings, and spacing materials. They are primarily constructed using "single pipes" on-site, which eliminates the need for large foundations. The posts are designed to be assembled on-site with standard single pipes and post frames used for the foundation. For more details, please feel free to contact us.

Detailed information
-
"Compliance with the conditions for performance verification through experiments in the Rockfall Mitigation Handbook" The QT fence has been confirmed to withstand rockfall energy up to 10 kJ through free-fall weight drop tests on actual specimens. The experiments adhere to the "performance verification method through experiments" outlined in the "Rockfall Mitigation Handbook (December 2017 revised edition / Public Interest Incorporated Association Japan Road Association)." By using products that have been verified for performance from the stage of temporary measures until the installation of the permanent mitigation works, safety on site can be improved.
-
Can be installed quickly with manual labor. Since the foundation is constructed using 'single pipes' primarily used on-site, it does not require a large foundation. With a simple structure and lightweight components, it can be easily installed and removed. It can be transported and constructed manually, which also shortens the installation time.
-
Materials can be stored as stockpiles. Since the materials can be stored compactly, they can be kept as emergency supplies for post-disaster measures. If there is no storage space, we can quickly deliver items stored at our factory. You can choose to procure single pipes locally or purchase them from us.
