technical field

The utility model relates to the technical field of detection equipment, in particular to an adjusting device for a bearing ratio experimenter.

Background technique

The load-bearing ratio tester is suitable for various soils and mixtures (soil with a particle size of less than 40mm) to carry out the load-bearing ratio test after compaction in the specified test cylinder mold to determine the designed pavement, pavement base, subbase, and roadbed materials. The bearing capacity of the layer is one of the necessary instruments for geotechnical testing.

During the load ratio test operation, it is necessary to place the object to be tested inside the container, press it, and then read the load data, but the traditional tester needs to load the container during operation. The penetration rod inside the box is in contact with the gauge ring at the lower part of the reading dial, and then it is tested and read, but the traditional tester uses the threaded cap and the threaded post to control the height of the reading dial because of its upper indication. It is difficult to use the naked eye to observe whether the moving distances are the same. If the deviation is too large, it may cause the measuring ring and the penetration rod to not be in contact, and it may also affect the accuracy of the test data to a certain extent, which will cause certain errors. , for this purpose, we propose an adjustment device for the load ratio experimenter.
