PREVENTER FOR CLOGGING WITH SEDIMENT OF WEEP HOLE IN DEBRIS BARRIER FOR FORESTRY CONSERVATION

摘要

PURPOSE:To simplify the structure and make setting operation easier by lessening the number of parts and also exactly prevent the clogging with sediment of the weep holes of debris barrier for forestry conservation. In addition, to prevent the degradation by water pressure and earth pressure by improving the strength of the barrier. CONSTITUTION:On the upstream side of a weep hole 2 formed in a debris barrier 1 for forestry conservation, a corrugated plate 3 with wave forms vertically by surrounding the hole 2 is set, and many weep openings 8 are formed in the faces directed upwards to the flow of water on the corrugated plate.
