Problems solved by technology

[0002] Point load test is a test method to obtain rock strength indirectly. It is widely used in rock mass engineering due to its rapidity, ease of operation, and strong adaptability to irregular specimens. However, the existing point load test The instrument is loaded with a manual pump, and manual loading will produce pressure fluctuations, which will lead to poor reliability of the test process and affect the stability of the rock sample point load test.

Abstract

The invention discloses a rock sample point load tester and a test method, and relates to the technical field of rock mechanics test instruments.The rock sample point load tester is characterized by comprising a clamping module and a loading module, and the clamping module comprises an upper pressing head and a lower pressing head which are used for clamping a rock sample; and the loading module comprises a jack and is used for driving the upper pressure head and the lower pressure head to extrude the rock sample and continuously and uniformly increase the pressure on the rock sample. According to the invention, the rock sample point load test process is simplified, the test time is saved, and the accuracy and reliability of test data are improved.

Description

technical field [0001] The invention relates to the technical field of rock mechanics test instruments, more specifically, it relates to a rock sample point load tester, and also relates to a rock sample point load test method. Background technique [0002] Point load test is a test method to obtain rock strength indirectly. It is widely used in rock mass engineering due to its rapidity, ease of operation, and strong adaptability to irregular specimens. However, the existing point load test The instrument is loaded by a manual pump, and manual loading will produce pressure fluctuations, which will lead to poor reliability of the test process and affect the stability of the rock sample point load test. [0003] Therefore, a new solution needs to be proposed to solve this problem. Contents of the invention [0004] The object of the present invention is to solve above-mentioned problem and provide a kind of rock sample point load tester. [0005] The above-mentioned techni...
