Technical Field

The utility model relates to the technical field of mold, concretely relates to a mould for making non-through joint rock sample.

Background

In geotechnical engineering, in order to research the influence of rock joint on rock strength, the rock needs to be tested, but the difficulty is higher when natural rock is prepared into a test piece suitable for the requirements of test equipment, and the test piece is damaged once, so that in the research process, in order to control variables, tests under different conditions need to be carried out on the same structural plane, which cannot be met when the natural rock is used as the test piece. Therefore, laboratory tests are generally conducted using similar materials instead of the original rock materials. Therefore, a test piece meeting the test requirements is required to be manufactured by using the die.

However, the test piece of non-through joint can not be made by the current test mould, and the test piece needs to be processed in the later period, which undoubtedly increases the consumption of manpower and material resources. Furthermore, the later-stage processing error of the joint is too large, and the length of the joint has some artificial errors and the variable cannot be strictly controlled to influence the accuracy of the test for the widths of the joints of different test blocks.

Therefore, how to design a mold for manufacturing a non-through joint rock sample becomes a problem to be solved currently.
