Background technology:
High polymer grouting curtain technique is a kind of new technology of processing dykes and dams infiltrations disease, this technology have quick construction, good seepage-proof property, cost low, to advantages such as dykes and dams disturbance are little, there is wide development and application prospect.But the detection technique to high polymer grouting curtain construction effect rarely has report, this makes the development of high polymer grouting curtain technique be subject to certain restriction.How the defect of fast detecting high polymer grouting curtain becomes the key of this technical development.
Virtual instrument technique utilizes high performance modularized hardware exactly, completes the application of various tests, measurement and robotization in conjunction with the software of high efficient and flexible.It has that performance is high, extendability is strong, the development time is few and the seamless advantage such as integrated, is widely used in, in data acquisition and test, if applied in high polymer grouting curtain defects detection, well solving the existing problem of prior art.
Summary of the invention:
The utility model is for the test problems of current high polymer grouting curtain technique slip casting effect, develop a kind of dam body high polymer grouting curtain defect detecting system, object is to provide a kind of detection system fast and effectively for high polymer grouting curtain technique slip casting effect.
In order to achieve the above object, the utility model by the following technical solutions.
Dam body high polymer grouting curtain defect detecting system, it comprises electrode catheter, wire, power supply, real time data acquisition disposal system, it is characterized in that: described electrode catheter is connected with real time data acquisition disposal system with power supply by wire, totally four of described electrode catheters, along dam body, move towards vertical distribution, there are respectively two electrode catheters high polymer grouting curtain both sides, two of outside for supplying electric probe, two of inner side is measuring probe, described real time data acquisition disposal system is passed through virtual instrument technology, can show in real time the ground resistivity between the probe of high polymer grouting curtain both sides, the ground resistivity of different depth can be measured in the position of traverse measurement probe, by finding the sudden change value of ground resistivity, can determine dam body high polymer grouting curtain defective locations.
The principle of dam body high polymer grouting curtain defect detecting system is: when defect does not appear in high polymer grouting curtain, because superpolymer is insulating material, impedance is very big, so the resistivity between cut-pff wall two lateral electrode M, N is great; And when defect appears in high polymer grouting curtain, because the soil body of rejected region can conduct electricity, the resistivity between two lateral electrode M, N is reduced greatly, then rejected region is surveyed in detail, constantly change the distance between two lateral electrode M, N, thereby determine the particular location of rejected region.
Concrete implementation step is as follows:
(1) A, two of B are inserted in the dam soil body for electric probe, open power switch.
(2) M, two measuring probes of N be connected and debugged with real time data acquisition disposal system, then two measuring probes of M, N being inserted from high polymer grouting curtain in the soil body close to, measuring ground resistivity.
(3) mobile M, two measuring probes of N, increase the distance of itself and high polymer grouting curtain gradually, continues to measure ground resistivity.
(4) when the situation that runs into ground resistivity and reduce suddenly, high polymer grouting curtain defectiveness herein is described, further measures and determine that the position of fault location also records.
(5) when M, two measuring probes of N move to two of A, B for electric probe place, complete first group of test, then along dam body move towards mobile M, N, A, tetra-probes of B carry out second group of measurement.
(6) repeating step (1)～(5), until complete the testing of whole high polymer grouting curtain.
Dam body high polymer grouting curtain defect detecting system makes full use of the insulativity of superpolymer and the advantage of virtual instrument technique, adopt the method for four-point probe measurment ground resistivity to detect dam body high polymer grouting curtain defect, there is the advantages such as quick, efficient, harmless, low-cost.
