Abstract

The embodiment of the application relates to the technical field of geotechnical engineering, in particular to a rock free expansion rate measuring instrument. The rock free expansion rate measuring instrument comprises a base, a bracket fixedly mounted on the base, a water container fixedly arranged on the base, an image acquisition device, and a controller. The water container is provided with an accommodating cavity which is used for accommodating a test sample and is provided with an opening in the top, and is made of a light-transmitting material; the image acquisition device is fixedly mounted on the bracket and is used for acquiring an image of the sample; and the controller is in signal connection with the image acquisition device and is used for receiving a sample image acquired by the image acquisition device and calculating a free expansion rate of the sample according to the sample image. According to the rock free expansion rate measuring instrument, manual reading and whole-course guarding are not needed, and problems that in the prior art, in the measuring process, the number of manual reading is large, labor consumption is large, and working efficiency is low are solved.

Description

technical field [0001] The present application relates to the technical field of geotechnical engineering, in particular, to a measuring instrument for rock free expansion rate. Background technique [0002] In the process of geotechnical engineering tests, in order to measure the free expansion rate of the rock, four radial measuring points which are symmetrical to the center are usually set on the circumference of the rock sample, and an axial measuring point is set on the top of the rock sample , measure the radial and axial measurement points at the same time through a measuring device such as a dial gauge, and calculate the free expansion rate of the rock according to the measurement results. [0003] During the measurement process, even if the rock sample can reach deformation stability three times before the test, at least 224 readings are required at the radial measurement point alone. The test process needs to last for 48 hours, and personnel need to be on duty all ...
