目的:求浅层地下水之渗透系数及涌水量和水位下降之关系及单位涌水量等。特点:设备简单,动水位容易控制,涌水量能得到较准确的数字。设备:(一)铁桶2个(圆柱体,容积20000—50000公分~3)其中一个铁桶作淘水用(如有手压泵或动力水泵时,此桶可不用),另一个铁桶放在探井中央,作容纳探井里渗出来的水用,此桶在桶内离桶口1公分处用红漆画一记号,由此记号开始往桶内20公分处,再画一记号。计容积时,以此记号内之体积计算(见图1)。
Objective: To find the relationship between the permeability coefficient of shallow groundwater and the drop of water inflow and water level, and the unit of water inflow. Features: The equipment is simple, the dynamic water level is easy to control, and the water inflow can get more accurate figures. Equipment: (1) 2 iron drums (cylinders, volume 20,000-50000 cm~3) One of the iron drums is used for watering (if there is a hand pump or power pump, this drum can be used), another drum Placed in the center of the exploratory well to accommodate the water seepage from the exploratory well, the bucket was painted with a mark of red lacquer at 1 cm from the mouth of the barrel. The mark began to move into the barrel at 20 cm and a mark was drawn. When calculating the volume, calculate the volume within the symbol (see Figure 1).
