摘要
水文地质研究工作中,当进行大流量抽水或注水试验时,淋滤水会在普通水位计表面,形成1层水膜,导致水位计还未入水,便已处于接通状态;或由于水体入井时,携带了大量空气,使水体表层形成1层具有一定厚度的气液混合物,无法获得连续稳定的地下水液面,造成水位计读数失真。为此,制作了一种简易水位计,将导线保护在外壳内,并将外壳加长至0.5 m。经实际验证,该水位计简单实用,解决了水位计因淋滤水或存在气液混合物而造成读数失真的问题,且数据可重复性好。
During the hydrogeological study work,when the high flow water drainage or water injection test were conducted,the leaching water would form a layer of the water film on the surface of the conventional water level gauge.And the water film caused the water level gauge with no water being in a connection condition.Or due to water in the well,great air would be brought in the well.Thus the water surface would form a layer with a certain thickness air and liquid mixture,a continued stable underground water liquid surface could not be obtained and the reading of the water level gauge would be distortion.Therefore a simple water level gauge was made,a conductor wire would be protected in the shell and the length of the shell would be increased to 0.5 m.The practice verification showed that the water level gauge was simple and practical,could solve the reading distortion of the water level gauge due to the leaching water or the air and liquid mixture and the data could have good repeatability.
