Steel Slit Dam can capture rocks securely in case of debris flow, but sediments can go through under
normal conditions.
Slit-type structure built by combining steel pipes, which does not disrupt river flow

Characteristics

Efficient Debris Flow Capture
– Transmission-enabled design forms sediment space under normal conditions and captures debris
during flow events.
High Shock Absorption and Accuracy
– Steel pipes with excellent energy absorption reliably capture sediment and rocks during intense debris flows.
Environmentally Conscious Design
– Maintains river continuity and minimizes ecological disruption.

Applications

Approx. more than 100 projects per year in Japan.
