Description
Technical field
The utility model is related to underground water identification sampling system technical field, and in particular to a kind of modularization underground water individual well
Multilayer identifies sampling system, and the system is applied to dirty in the investigation of complex site high accuracy, place underground pollution identification identification, underground
The industries such as thing analysis are contaminated, the underground water pollution sample that different depth layer position is collected in individual well is disclosure satisfy that, reaches differentiation not
With underground water pollution degree and the purpose of scope.
Background technology
Groundwater monitoring well is the engineering mode that a kind of conventional place groundwater environment is assessed, and is to grasp groundwater dynamic
Variation characteristic, evaluation of subterranean water resource, investigation underground water pollution, the important measures for carrying out the work such as groundwater monitoring.Underground water
Monitoring well provides sample collection platform for underground water analysis detection, and the structure of groundwater monitoring well, the quality of quality determine ground
Data stability, relevance and the integrality of lower water sample analysis result.The existing more practicality of individual well multilayer sampling monitoring well
New and apply precedent, the honeycomb well that such as eighties of last century occurs the nineties is filled out in outer well by being layered well in insertion, layering
Enter the mode of filtrate and airtight and watertight padding, also known as " cellular monitoring well ", in interior well place immersible pump, self priming pump progress machinery and adopt
Sample, or manually gathered using artificial Beile's pipe;And for example the CTM systems of Solinst companies of Canada research and development in recent years, pass through
The manufacture craft of PVC well casings in monitoring well is improved, multiple water passages, each water passage list are designed in a PVC well casing
Solely one layer of water-bearing layer of circulation, and monitor the water level and water quality in this layer of water-bearing layer.
It is dirty for heterogeneous high, a fairly large number of formation feature in stratum as space enrironment investigates the development of industry
Contaminate the required precision more and more higher of investigation, it is especially vertical on be even more to need scientific and effective to know to the pollution range of underground water
, do not judge and identify.Identification to place underground water pollution depth, is used as generally according to water level depth, water quality condition and sentences
Disconnected foundation, therefore the difference of groundwater monitoring well sampling platform determines the identification of pollution surveys basis for estimation, and investigate
As a result validity.
The application of technology is generally all constantly updated with the development and change of industry.The Cheng Jing of above-mentioned individual well multilayer sampled well
Technique is mostly using the construction method for loading well casing after traditional pore-forming, although suitable for water level monitoring, hydrogeological parameter
The industries such as measure, but when the vertical pollution for complicated underground water pollution type, small yardstick Pollution Field is distributed identification problem,
Often because of pore-forming shaft building during, drilling time length, the cross pollution of pollution of underground aquifers thing, Cheng Jinghou upper aqueous layer
Lower water is more flowed into bottom aqueous layer along drilling wall, is mixed with bottom aqueous layer underground water, is polluted arrival depth and is known
It is not difficult and produce investigation result erroneous judgement;Secondly, individual well multilayer monitoring well is also possible to the limitation because pipe well in work progress, makes
Well casing is intensive in into single hole, and well casing quantity is more especially in upper aqueous layer hole, narrow space causes closure filler to fill out between well casing
Dress is not tight, and underground water occurs more to flow in bore inner between water-bearing layer, pollutes thing and is penetrated in aqueous interlayer, it is difficult to is distinguished
The parameters such as the aqueous water quality water level of position layer by layer;Again, the investigation phase, into well process as penetrated more flow phenomenon, causes upper strata on the contrary
Pollutant spreads on vertical to deeper stratum, pollutes the risk that scope expands, degree is aggravated.Therefore, above-mentioned technology without
By being that well drilling technology or practice of construction etc. are all likely to result in the cross pollution of pollutant underground, pollution depth and determined, or actually apply
The problems such as work is difficult, in turn results in that liability for polution is difficult to differentiate, the regulation of subsequent contamination place improves more difficult carry out.
