Description
Technical field
The present invention relates to a kind of device and method for detecting dam seepage entry position, and in particular to a kind of constant-current field method is visited
The device and method of dam seepage entry position is surveyed, belongs to water conservancy dam hidden danger technical field of measurement and test.
Background technology
China is the multiple country of flood, substantially annual all to occur flood damage in different regions or river, is made
Into loss it is very huge.The immediate cause for causing flood damage is to break down or breach a dyke.In fact, earth dam or earth embankment burst before be
There is tendency, find piping after dykes and dams before this, and piping occurs dykes and dams and burst again after developing after a while.State in 2000
Interior R＆D institution have developed levee piping and seepage detector, and produced approved product in 2006 and promote the use of.Use this
Product can find seepage entrance in the dykes and dams upstream waters for having piping, and hydrotechnics personnel can refer to according to test result
Emergency flood fighting troop closure seepage entrance is led, dam break is eradicated and breaches a dyke dangerous situation.
The levee piping and seepage detector used at present is that exchange is set up between leakage passage is exported to the preceding waters of dykes and dams
Electric field, if dykes and dams have leakage passage, the electric current that will produce internal field in seepage entrance Its Adjacent Waters before dykes and dams is close
Degree and electric-field intensity become big phenomenon, when the probe of levee piping and seepage detector tests the local current densities into dykes and dams preceding waters
Or the unusual big position of change of electric-field intensity, it also just have found dam leakage entry position.
Actually used this levee piping and seepage detector finds that, due to skin effect phenomenon, dykes and dams do not have seepage entrance
When, the current density and electric-field intensity that water bottom location electric field is closed in waters be also it is elevated, to judge before dykes and dams it is water-bed whether
It is truly present dam leakage entrance and brings difficulty, often occurs failing to report or misrepresent deliberately seepage entrance situation, had a strong impact on equipment spy
The accuracy rate of result is surveyed, is the urgently to be resolved hurrily and long-term technical barrier not being resolved.
The content of the invention
Kelvin effect can increase Electric field edge current density, and increase degree is directly related with the frequency of electric field, and electric field is frequently
Rate is higher, and Kelvin effect effect is more notable, during constant current electric field (electric field frequency is zero), does not produce skin effect phenomenon.The present invention
According to this principle, dam seepage entry position is detected using constant-current field method, makes to close in the electric field of waters in the absence of Kelvin effect
Water bottom location current density and electric-field intensity increase phenomenon, efficiently solve failing to report for existing levee piping and seepage detector presence
Or misrepresent deliberately seepage entrance position sensing ramification problem.
The present invention adopts the technical scheme that to solve the above problems：Device of the present invention includes constant current transmitter, A poles
Plate, B pole plates, A pole plates connecting line, B pole plates connecting line, probe and constant current receiver, A pole plates are arranged on dam leakage and go out saliva
In, B pole plates are arranged in the preceding waters distant place water of dykes and dams, and constant current transmitter is arranged between A pole plates, B pole plates, and A pole plates pass through A poles
Plate connecting line is connected with constant current transmitter, and B pole plates are connected by B pole plates connecting line with constant current transmitter, and constant current receiver is set
In ship on the preceding waters water surface of dykes and dams, probe is arranged in water, and probe is connected by data wire with constant current receiver.
The method of the invention is comprised the following steps that：
Step 1: constant current transmitter is placed between A pole plates, B pole plates, A pole plates, which are arranged on after dykes and dams, leaks out saliva
In, B pole plates are arranged on the preceding waters distant place of dykes and dams, and A pole plates are connected by A pole plates connecting line with constant current transmitter, and B pole plates pass through B
Pole plate connecting line is connected with constant current transmitter；
Step 2: constant current receiver is placed on before dykes and dams in the ship on the water surface, the probe of constant current receiver connection is put into water；
Step 3: opening constant current transmitter power, constant current transmitter water before dykes and dams and dykes and dams by A pole plates and B pole plates
Constant current electric field is set up in domain；
Step 4: constant current receiver power supply is opened, the water before dykes and dams with hull of the probe in boat-carrying constant current receiver and water
Domain is moved, when the probe in water is adjacent to leakage passage entrance, and probe can just detect constant current electric field and increase extremely here
Electric-field intensity or current density value, find seepage entrance.
The beneficial effects of the invention are as follows：1st, constant current transmitter of the invention by pole plate A, pole plate B in leakage passage and dike
What is set up in the preceding waters in dam is DC electric field, without the intrinsic skin effect phenomenon of AC field, the electric current of electric field in waters
Distribution is only related to engineering structure and leakage passage entry position, drastically increases the accuracy rate that system detects achievement, effectively
Avoid wrong report, fail to report the generation of leakage passage Entrance Problem.
