A device for field survey and measurement of groundwater level comprises a tape ruler, a stainless steel barrel and a plumb cone body; the zero-point end of the tape is provided with a circular hole ring; the top plane of the plumb cone body is provided with a central ring; the stainless steel barrel is in a closed thin-walled hollow shape; and the upper plane center and the lower end of the stainless steel barrel are arranged with a central ring. A stainless steel ring with opening and closing locking is arranged at the center of the surface circle; the stainless steel ring passes through the 0-point end hole ring of the tape and is locked; the stainless steel ring at the bottom end circle of the stainless steel drum passes through the plane central ring at the top of the lead-drop cone and is locked; and the connecting body of the lead-drop cone and the stainless steel drum is locked. In the pure water with a specific gravity of 1, the water level line is located at the 1/2 part of the stainless steel cylinder. Beneficial effect: The common tape used in field survey is used as traction parts, the stainless steel cylinder with scale is used as semi-submersible body, and the plumb cone is used as sinking traction parts. It has the characteristics of simple structure, easy maintenance and non-damage.

一种野外勘察测量地下水位的装置
本技术涉及水文测量
,尤其涉及一种野外勘察测量地下水位的装置。
技术介绍
在野外勘察、施工排水、地下水供水等水文勘察监测时,都需要监测地下水位的变化。传统的测量方法有简易测法和专用仪器测法两大类。简易测法直接用测绳拴重物凭感觉或听到击水声观测,误差较大,不满足勘察规范要求的±2cm的精度要求。专用仪器测法就是利用水的导电性,用电池组提供直流电源,在水面处设置分开的带电触头,接触到水面后,电路接通,显示灯亮,此时测尺显示的数值即为地下水位埋深。该方法虽然便捷,但存在设备相对复杂,易损坏的缺点。
技术实现思路
本技术针对现有技术的不足,提出了一种野外勘察测量地下水位的装置,该装置具有结构简单、使用方便、测量精度高且维护容易的特点。一种野外勘察测量地下水位的装置包括皮尺、不锈钢圆桶、铅坠锥形体;所述皮尺的0点端头设置圆孔环所述铅坠锥形体的顶端平面设置有中心圆环;所述不锈钢圆桶呈密闭薄壁空心状;在所述不锈钢圆桶上端平面圆心处及下端面圆心处设置可开启和闭合锁止的不锈钢圆环;所述不锈钢圆环穿过皮尺的0点端头圆孔环并锁止;所述不锈钢圆桶下端面圆心处的不锈钢圆环穿过铅坠锥形体的顶端平面中心圆环并锁止;所述铅坠锥形体及不锈钢圆桶的连接体在比重为1的纯水中静止时,水位线位于不锈钢圆筒的二分之一部位。进一步的,所述不锈钢圆桶侧壁上以上端平面为起始0点做四等分标尺刻度(刻度自上而下依次增大),以毫米为单位。本技术所述技术方案的有益效果在于:利用阿基米德定律,设置半潜体,达到静力平衡时,存在唯一的水位浸润线,利用浸润变色试纸标识水位线,具有精度高的特点 ...
