TS-DC Delta

Area of Application

The TS-DC Delta is a debris flow barrier designed for large and difficult loading conditions. Unlike prefabricated systems used for rockfall mitigation, debris flow barriers must always be designed on a site-to-site basis to account for the highly variable characteristics of debris flow processes and their interaction with site topography.

Self Supported

One of the key features is that the posts are self supporting which means that no upslope retaining ropes are required. This is important because any anchors or ropes located upstream of the system will be impact by a wall of debris that could cause the system to fail. A large brace connects the upper portion of the primary post to the back of the foundation and so the support is protected by the structure itself.

Rope Guidances

The upper and lower bearing ropes are led through a rope guidance that is integrated on each post head and base plate. The middle ropes are attached to integrated post guidances. The guidance is designed to be robust and with no movable parts in order to ensure longevity and zero maintenance.

Lateral Anchorage

The system can be anchored at the open ends of the fence or internally using standard anchors or reinforced anchorage. This allows a barrier to be built in long sections, as well as be applied to areas with unconfined flows such as within debris cones. Long barriers consist of multiple sections of fencing that act independently.

Upslope Clearance

Debris Catchers are designed to address various maintenance requirements based on owners’ needs. For example, zipper seams can be installed to allow disassembly in particular fields. The unique characteristics of the Omega-Net combined with the zipper permits the system to be opened like a drape and gives access to heavy machinery for debris removal. The lack of retaining ropes on the upstream side of the system also greatly reduces the cost of maintenance following an event.

AVT-phx Brake Elements

The AVT-phx series of brake elements are steel coils that unravel when a force is applied. The gauge, width and number of coils can be specified in order to control the amount of energy absorbed and the total displacement. With no moving parts, these are some of the safest and most reliable brakes in the industry.
