Description
One,
Technical field:
The utility model belongs to native resistivity measurement technical field, particularly the device of the native change in resistance of test under a kind of artificial environment.
Two, background technology:
The resistivity of soil is the concrete sign of the electric conductivity of soil, be micromechanism, the metal erosion of research soil, the important parameter of soil pollution, power ground, lightning protection, anti static grounding and infer that the aspects such as engineering mechanics property of soil have extremely important practical value.The resistivity of soil is all multifactor concentrated expressions such as the particle composition, architectural feature, salt feature, water regime, temperature characterisitic of soil, in the laboratory, there is not special-purpose, desirable proving installation at present, can not carry out native resistivity with the dynamic test of moisture, temperature variation, especially be not easy to testing research under freezing conditions.In the middle of the real work, in order to obtain the resistivity data of soil, common way is to select weather condition stable, does not have precipitation in nearly five days, carries out open-air field test under the situation that the earth does not freeze.Because the restriction of test condition, it is very limited to obtain data information, or even isolated single data, can not reflect the resistivity truth of soil comprehensively, more can not reflect the rule that changes with temperature, moisture of the resistivity of soil, especially there is being frost zone where, the limitation of original position field test is particularly outstanding, can not provide reliable native change in resistance data for engineering design, and the testing cost height, test environment is poor, wastes time and energy.
Three, summary of the invention
The purpose of this utility model is to solve the problem that present test soil resistivity exists, the device of the native change in resistance of test under a kind of artificial environment is provided, with obtain soil within the specific limits moisture, temperature to the change in resistance rule of soil, the variation amplitude of fluctuation that finds the native resistivity of test may exist under field conditions (factors) is for engineering design provides reliable native resistivity basic data.The technical scheme that the utility model is intended taking is: the device of the native change in resistance of test under a kind of artificial environment, it is characterized in that housing (8) upward fixedly has two rhones (11), uniform 4～8 water injection holes (6) in every rhone (11), water injection hole (6) is done liner with insulating material, uniform 4～8 instrument connections (10) between two rhones (11), instrument connection (10) is done liner with insulating material, the inwall of housing (8) has insulated liner (7), the two ends of housing (8) are provided with bearing plate (13), the one side of bearing plate (13) fixedly has four groups of springs (14), the other end of spring (14) links to each other with plug (1), be provided with pressure transducer (4) between bearing plate (13) and the plug (1), pressure sensor data line (3) is drawn from plug (1), the another side of bearing plate (13) fixedly has insulcrete (12), insulcrete (12) is gone up fixedly copper coin electrode (9), copper coin electrode (9) links to each other with electrode (15), electrode data line (2) is drawn from plug (1), the plug (1) at housing (8) two ends links to each other with 4 screw rods (5), and screw rod is screwed with nut on (5).The utility model is to use like this, to test the soil rough compacting in the housing (8) of packing into earlier, tighten the nut on the screw rod (5) again, pressure by pressure transducer (4) determination experiment soil, according to different experimental situation requirements, by uniform 4～8 water injection holes (6) water filling in the tank (11), reach the moisture requirement of experiment soil, again according to the requirement of experimental situation to stability, with the utility model heating or freezing, by copper coin electrode (9) and electrode (15) with insert instrument connection (10) but water cut 0～50% under the interior electrode measure analog environment, temperature-40 ℃～45 ℃ of native resistivity, to obtain soil moisture within the specific limits, temperature is to the change in resistance rule of soil, the variation amplitude of fluctuation that finds the native resistivity of experiment may exist under field conditions (factors) is for engineering design provides reliable native resistivity basic data.The utility model can overcome existing apparatus or can not enter environmental cabinet realizes the climatic simulation test, install deficiency too simple and crude, that structure is too simple, material therefor can not be tested under rugged surroundings, satisfy the actual needs of the native electrical resistivity property research under frozen soil condition, the desert condition.The utlity model has characteristics simple in structure, convenient and practical.
