Description
Technical field
The utility model relates in the surface water and groundwater in environmentology in dynamic coal-mining subsidence pools zone, hydrology more
Flow rate calculation field, and in particular to a kind of dynamic sinking land in coalmining areas underground water and surface water water level difference measuring device.
Background technique
Coal is the main energy sources in China, and the North China Plain is one of the coal main producing region in China, due to the thickness pine of this area
The background condition for dissipating layer, high ground-water level, results in the formation of a large amount of coal-mining subsidence pools zone, changes the original water in the region
Literary circulation pattern, wherein the more stream exchange of surface water and groundwater is important one of cycling element, due to persistently sinking for earth's surface
It falls into, leads to the complexity of the SEA LEVEL VARIATION of surface water and groundwater, mainly include following factor: (1) due to earth's surface rainfall
SEA LEVEL VARIATION caused by process；(2) SEA LEVEL VARIATION caused by changing due to atmospheric pressure；(3) since subsidence leads to elevation
Change and gives SEA LEVEL VARIATION bring overlaying influence.China is water shortage country, and North China Plain area is even more so, from country, province, city
The protection and comprehensive utilization to Subsidence Area water resource are all paid much attention to etc. departments at different levels, proposes Subsidence Area construction " Wall in Plain Reservoir "
Conception, and had been carried out corresponding engineering measure, the water resource in the rational evaluation region is the key that be comprehensively utilized.Nothing
By being the calculating for carrying out water resources quantity using numerical value calculating or analytic method, the water-head of surface water and groundwater is accurately obtained
It is the key that be computed correctly surface water and groundwater to get over flow.
Currently, the monitoring method of existing surface water, underground water is largely the sight individually for surface water or underground water
Examining system, or surface water and groundwater is integrated into a device using law of connected vessels, the difference between water level is obtained,
Two kinds are broadly divided into according to the type of communicating pipe:
(1) surface and ground water is connected with the connecting tube of earth's surface, by being arranged in groundwater observation well
The pressure difference of sensor reading underground water and surface water.
(2) embedded underground horizontal pipeline is connected to surface water and groundwater, obtains underground by measurement internal and external casing water-head
Water and surface water pressure difference.
Both measurement methods can carry out the water level monitoring of long-term surface water and groundwater, tight but there are following two
Weight is insufficient:
(1) due to being connected between surface water and groundwater by pipeline, earth's surface communicating pipe is easy to produce bubble, subterranean communication
Tube capacity easily blocks, and causes measurement inaccurate.
(2) groundwater observation well must not be too far away with surface water distance, can only construct on bank, deeper for Groundwater buried depth
Area, increase the difficulty of construction.
In addition, the depression of the sinking land in coalmining areas is always along with process of coal mining, Subsidence Range and depth also will be with
Change together, on bank, the hydrological observation wells of construction cause measuring system to fail easily as depression is by earth's surface water submerged.Cause
This, establish can surface water and groundwater water-head monitoring system accurate, being used for a long time be to carry out coal-mining subsidence pools zone water
The key of stock number exchange research.
