The invention provides an anti-sticking measuring wire for groundwater level measurement, which comprises a conductor, a metal rope and a metal elastic element; a conductor includes a core wire in an insulating skin and an insulating skin; a metal rope and a metal spring element are wound outside the conductor in turn from inside to outside and are insulated and contacted with the conductor; and the core wires at both ends of the conductor are exposed. Because the metal rope and the metal spring element winding in turn from inside to outside the conductor and insulating contact with the conductor, the conductor acts as isolation and conduction in the center, the metal rope acts as an increase in toughness and tensile force, the metal elastic element winding in the outside, can make it under its own gravity to maintain a straight state, so as to measure the line in the absence of. Under the condition of plumb, it can still be vertically inserted into the well where the groundwater is located. Because it does not need to hang heavy objects, the overall thickness of the survey line is almost the same, and the change of the thickness will not cause blockage during the process of insertion and removal. At the same time, the toughness of the anti-blockage survey line makes it difficult for other wires in the well to be entangled.

一种用于地下水水位测量的防卡测线
本专利技术涉及测量领域,更具体地,涉及一种用于地下水水位测量的防卡测线。
技术介绍
全国地下水水位监测是国家公益性项目,监测井数量庞大,监测工作繁重,以河北省为例,各级监测井共有4100多口。目前,通常测量水位方法是:将两根导线一端的绝缘皮拨开,使两根导线的金属芯彼此相临裸露,但不相连,系好铅锤,另一端连接毫安(微安)电流表。让导线在铅锤的重力下慢慢进入井中,当导线入水,两根导线就会在水中导通,电流表指针就会摆动。当导线到达水面时即刻停止放线,通过测量放入导线的长度,得到地下水的水位。以上方法虽然是目前最常用的方法,但存在着一定的弊端。在测量过程中重物或导线经常被井中的导线、水管、吊绳卡住,遇到深井或口径小的井往往没办法解开,只能把测线拽断,这样不仅经常损坏测量工具,还可能将井里的线缆拉断,引起更大的麻烦,给原本繁重的工作带来极大的不便。
