Description
Technical Field
The utility model belongs to the technical field of rock point load test device, in particular to irregular rock mass length measurement structure and have rock mass measurement function's point load appearance.
Background
The point load test is a simple method for testing the compressive strength of rock, concrete or other natural building materials under point load. During the test, the sample is clamped between two spherical loading conical heads, load is applied until the sample is fractured, and the tensile strength of the sample can be obtained according to the maximum load when the sample is damaged and the distance between the end points of the two conical heads, so that the compressive strength of the sample can be calculated empirically. The method has the advantages that the instrument and equipment are portable, the instrument and equipment can be carried to the field for testing, the sample does not need to be processed, and test data can be obtained in time. The point load test is a test for measuring the rock strength, is mainly used for rock classification and rock anisotropy measurement, and can calculate the uniaxial compressive strength and tensile strength of the rock. Because the test piece can directly select and use the drilling rock core and irregular rock blocks, the method is suitable for the field, in particular to weathered rocks, weak broken rocks and the like which are difficult to prepare samples in indoor tests.
The point load instrument is a common device for performing a point load test, for example, a portable digital rock point load instrument disclosed in chinese patent document CN208443659U, but the conventional point load instrument is very inconvenient for measuring natural and irregularly-shaped rocks during performing the point load test.
