深浅管井由于常年抽水,带动含水层泥砂堵塞管外填砾,铁的氧化也是导致管井滤水层堵塞的原因。为恢复滤网的滤水能力,1978年曾进行了水锤洗井试验,收到了良好的效果。动水位回升3.66～8.98米,洗前单位涌水量为5.25～15.9米~3/米·时。洗后单位涌水量为10.5～28米~3/米·时。通过不同月份的水文动态观测,达到了正常最大出水量而且一直趋于稳定。
Due to the long-term pumping, the deep tube wells cause the silt in the aquifer to clog the outside of the pipe. The oxidation of iron is also the cause of blockage in the drainage pipe of the well. In order to restore the filtration capacity of the filter, the water hammer well cleaning test was conducted in 1978 and received good results. The dynamic water level rose 3.66 to 8.98 meters, and the amount of water before washing was 5.25 to 15.9 meters to 3/meter. After the washing unit, the amount of water inflow is 10.5 to 28 meters to 3/meter. Through the observation of hydrological dynamics in different months, the normal maximum water output has been reached and has been stable.
