Semi-automatic titration apparatus and testing method

Abstract

The invention provides a semi-automatic titration apparatus and a testing method. The semi-automatic titration apparatus comprises a test bed, wherein a fixed rod is arranged on the test bed and is connected with a movable rod through a bolt; the movable rod is provided with clamping pieces; the movable rod is used for fixing a flat panel through the clamping pieces; holes are formed in the flat panel; capillary tubes are placed in the holes; and a liquid box is arranged aside the test bed. The semi-automatic titration apparatus has the advantages of simple structure and low cost; and moreover, the problem of troubleshooting of different diameters of titrating tubes before an experiment can be solved; the accuracy of a test is improved, semi-automation is realized, workload is reduced, anda titration experiment on rock samples can be simply, effectively and accurately carried out.

Description

Technical field [0001] The invention relates to the field of geotechnical engineering, in particular to a semi-automatic titration device and a test method. Background technique [0002] In rock engineering, the research on internal damage of rock has received more and more attention from scientists. At this stage, the detection of rock sample damage mainly uses ultrasonic detection, CT scan, acoustic emission, etc. Most of the detection processes are complicated and the instruments are expensive. Based on this status, a simple and easy-to-operate capillary infiltration test method is proposed. [0003] Through a large number of titration experiments, the following problems have been found: 1) Because of the small inner diameter of ordinary capillary tubes on the market, there is an uneven inner diameter, which is not easy to detect with the naked eye; 2) When comparing different samples, it is often necessary Ensure that the test conditions are consistent, that is, the test tempe...

Problems solved by technology

At this stage, ultrasonic testing, CT scanning, acoustic emission, etc. are mainly used to detect rock sample damage. Most of the detection processes are complicated and the instruments are expensive. Based on this situation, a simple and easy-to-operate capillary infiltration test method is proposed.

[0003] Through a large number of titration experiments, it is found that there are the following problems: 1) The common capillary on the market has uneven inner diameters because of its small inner diameter, which is not easy to detect with the naked eye; 2) When comparing different samples, it is often necessary to Ensure that the test conditions are consistent, that is, test temperature and humidity, etc.; 3) Before titrating the test, the capillary needs to be placed in the titration solution to absorb the titration solution, but it is often difficult to ensure that the depth of the capillary into the water is consistent; 4) The test process requires human hands Fixed, labor-intensive and time-consuming, it also affects the accuracy of the test
