水文地质普查中,设立潜水井的目的,在于观测地下水位,水温变化,地下水运动情况,以及进行水质分析等等,提出可靠的水文地质资料。潜水井的建设好坏,对以上资料影响很大,故潜水井的设计安装是勘测地下水动态的一项重要工作。为此介绍一下我处所采用的缝式潜水井使用情况,仅供各单位参考。缝式潜水井是由纲式滤水管井改成的,具体使用方法如下:(一)用1.2—1.3公分厚,4—6公分宽,长4公尺的木板条以不锈金属箍或6—8号带铅皮的铁线捆成一个圆形的井筒,井筒外口直径18—20公分,井筒下端每隔8—10公分钻一小孔(直径1公分左右),交错形排列,长达50公分,便于水在井内流动。井箍的间距
In the hydrogeological census, the purpose of setting up a submerged well is to observe the groundwater level, change of water temperature, groundwater movement, and conduct water quality analysis, etc., and put forward reliable hydrogeological data. The construction of submersible wells has great influence on the above data. Therefore, the design and installation of submersible wells is an important task in surveying groundwater dynamics. To this end, I would like to introduce the use of slotted submersible wells in my area. It is only for the reference of various units. Sew-type submersible wells are changed from Gangue-type wells to water wells. The specific methods of use are as follows: (1) 1.2-1.3 cm thick, 4-6 cm wide and 4 m long wood strips with stainless steel ferrules or 6 - The 8th wire with lead skin is bundled into a circular wellbore. The outer diameter of the wellbore is 18-20 centimeters. The lower end of the wellbore is drilled every 8-10 centimeters (a diameter of about 1 centimeter), staggered and arranged. Up to 50 cm to facilitate the flow of water in the well. Well hoop spacing
