Features

Ideal for no-flow mountain streams

A mountain stream with an unclear flow path and no continuous running water where no sediment movement is expected during normal times is called a non-flowing mountain stream. The JD fence can be installed in such streams as the main countermeasure against debris flows and driftwood. Structured with a simple combination of steel pipes and H-shaped steel beams, it is an effective countermeasure against relatively small-scale landslides and driftwood disasters.

Excellent capture performance

The interval between horizontal members (steel pipes) of JD Fence is 20 cm, which reliably captures earth, sand, and driftwood to prevent disasters.

Reasonable structure

Thanks to its simple structure combining steel pipes and H-shaped steel beams as well as modular sections, it can be installed flexibly on various terrain. In addition, the members are connected with bolts, making replacement work easy.

Foundation profile adjusted to ground conditions

Two types of foundation are available: concrete foundation and pile foundation. The optimum foundation profile can be selected according to the ground conditions on site.
