  1. Effective capture of debris flow.
    Transmission-enabled structure that creates sediment accumulation space under normal conditions and effectively capturing sediment and rocks flow during debris flow
  2. Accurate capture of debris flow.
    Even in the onslaught of debris flow, steel pipes hat excel in shock absorption effectively capture sediment and rocks flow
