Flood protection dyke system inserts concrete wall deep into ground and of water-protective height plus grating stones to sides on gravel bed for grass etc to grow through as further dyke reinforcement and stability.

摘要

A concrete wall is sunk deep enough below ground to prevent seepage and weak point leakage above, the wall being of sufficient height to keep floods out. Grating stones are placed to both sides of the wall to give angle 30-90degrees between stone wall and stone level. The grating stones are underlain with gravel and are heavy enough to prevent their being washing away by the water flow.
