Description
Technical field
The invention belongs to level measuring technical field, be specifically related to a kind of water level metering device, particularly a kind of subsoil water
Water level metering device.
Background technology
Water is the natural resources that human survival and development is relied on, and seems more precious in today of water resource worsening shortages
Expensive.Wherein subsoil water is as important resource of water supply, the aspect such as is drinking, municipal, industrial, agriculture at human lives, national warp
Ji is built and plays an important role in social development.Investigate the purpose that the objective law of groundwater occurrence and formation is important,
First consist in how reasonable development and sustainable utilization groundwater resources.In the place that groundwater resources are barren, we are to be done just
It is searching ground water, but to do is to how to utilize, protect this portion at our more need of the more rich place of groundwater resources
Divide resource, and the geologic Environment Problem that exploitation reducig subsoil water or the motion due to subsoil water itself are caused as far as possible.
Human being's production and life activity are existed by subsoil water in some cases, and the mechanics purpose of monitoring subsoil water exists
In being lowered so that elimination subsoil water harm as far as possible, such as, monitor the change of groundwater level, prevent mine pit water discharge in mine, dash forward
The security incident that water etc. cause.
But groundwater resources relatively surface water resources is complicated, the therefore change of the quality and quantity of subsoil water and cause underground own
The environmental condition of water change and the migration rule of subsoil water can not directly be observed, and meanwhile, the pollution of subsoil water and subsoil water surpass
Adopting the surface subsidence caused is slow change type, once runs up to a certain degree, just becomes irreversible destruction.The most accurately develop
Protection subsoil water is necessary for relying on long-term groundwater monitoring, grasps dynamic situation of change in time.
From the point of view of most of groundwater resources survey taskses, the elementary item of groundwater dynamic monitoring all should include underground
Water water level, water temperature, water quality, the water yield etc..To having surface water water level and the flow of hydraulic connection with subsoil water, and mine working and
The EXIT POINT of other ground water engineerings, displacement and water level elevation also should be monitored.
In recent years affect the geological disaster phenomenon caused for a long time again and again to occur due to subsoil water, cone of depression, surface subsidence,
Crack, karst collapse, seawater invasion, water pollution etc., while generating a panic, remind people complete to the monitoring of subsoil water
The space that face property, accuracy also improve a lot.
By the research of groundwater level, it will be appreciated that subsoil water is under field conditions (factors) or the fortune of disturbed Water Under
Dynamic.In porous media.Mutually restrict, therefore in the process of monitoring owing to affecting the factor complexity of groundwater activities rule
In bring many troubles；Meanwhile, the surface subsidence that the pollution of subsoil water and groundwater mining cause is slow change type, once amasss
Tiring out to a certain extent, just become irreversible destruction, therefore accurately exploitation protection subsoil water is necessary for relying on long-term subsoil water
On-line monitoring, level of ground water are monitored automatically, grasp dynamic situation of change in time, pinpoint the problems and propose in long term monitoring contrasts
Solution.
The distance on surface to the ground of the water body existed with Free water form in underground is groundwater level.Well is utilized to do
Two kinds of better simply ways are commonly used: 1, electrical measuring method during groundwater dynamic water level monitoring, 2, listen clock method, i.e. at the zero graduation of rope chi
If electrode (wire) or clock (bell), roll off the production line, see note rope footage value when table is dynamic or listens clock to ring.When both approaches is actually used
The most very inconvenient, and it is not accurate enough to be affected measured value by outside environmental elements.If electrical measuring method is in the environment that underground is moist,
Electrode moisture-sensitive wet environment affect false triggering, cause measuring inaccurate；And listen clock rule to need well to be straight, at some
Being difficult in environment realize, the well of bending is then not suitable for use and listens clock method.And two kinds of methods are required to monitoring personnel to be had quite
Many experiences, the most key, both approaches is required to monitoring personnel and measurement is repeated several times, and can not realize supervising in real time
Survey.
