要保証旱井能够長期使用,除了注意質量以外,还必須注意旱井的防淤。旱井淤积庫容的增加,就相对的减少了蓄水庫容,尤其是黄土丘陵区的旱井,大多数是蓄积坡面徑流,合泥量大,如果不注意防淤措施,就会很快淤廢。
To ensure long-term use of dry wells, in addition to pay attention to quality, we must also pay attention to anti-silt dry well. The increase of siltation volume in the well reduces the storage capacity relatively, especially the dry well in the loess hilly region, most of which is the accumulation of runoff on the slope surface. The amount of combined mud is large. If we do not pay attention to anti-silting measures, it will soon silt Waste.
