Background
The rock-like material is a test block which is prepared by stirring and pouring materials such as cement, pebble, sand, water and the like according to different mixing ratios and has similar mechanical properties to natural rock. The pouring of the rock-like test block reduces the difference between the mechanical properties and the workability of two different test blocks, and simultaneously improves the test block manufacturing efficiency in the rock test. However, in natural rock, rock cracks such as joints, bedding, faults and the like are in a large number, so that more and more experimenters begin to pour rock-like test blocks with prefabricated cracks for better simulation of natural rock, which also means that the precision requirement of the prefabricated cracks during pouring of the rock-like test blocks is greatly improved.
The traditional method for prefabricating cracks mainly comprises manual cutting and prefabricated steel sheet insertion. And manual cutting, namely cutting the poured and maintained rock-like test block by using a cutting machine according to the requirement of the prefabricated crack. And the prefabricated steel sheet is inserted in the process of pouring the rock-like test block, the steel sheet is manually inserted and fixed according to the prefabricated crack requirement, then rock-like materials are poured in, and the hand is taken away after the steel sheet is fixed. The two methods for prefabricating the cracks are difficult to meet the requirement of controlling the crack precision in the process of prefabricating the cracks of the rock-like test block, and the inaccuracy of the prefabricated cracks is increased due to the inclination change which is difficult to be detected by naked eyes or hand senses in a direct manual cutting or manual insertion mode, so that the accuracy of experimental data is influenced. Therefore, it is necessary to design a pre-crack mold for laboratory test blocks.
