Description

[0001] The utility model belongs to the technical field of rock mechanics test molds, and in particular relates to a multi-layer test rock sample preparation device. Background Art

[0002] Physical model test is a commonly used research means and method in rock mechanics and engineering. The correct selection of similar materials is the key to correctly simulating engineering prototypes. In the simulation of rock mechanics and engineering samples, cast concrete is often used as the main material as a similar material. At the same time, in actual engineering prototypes, the strata are often distributed in layers and often face complex geological conditions of multiple strata. If the simulation of complex geological conditions is to be achieved, it is inevitable to involve multi-layer test rock sample casting methods. The existing test rock sample casting method has the following problems: 1) The current test rock sample block casting mold can only cast test blocks with a single ratio, which cannot simulate the field conditions well; 2) The existing laboratory-scale sample casting device cannot realize device integration and sample preparation automation; 3) The existing test rock sample block casting mold has a relatively single function. When using quick-setting materials to cast layered rock samples, the rock samples solidify unevenly and there are a large number of bubbles, etc., which leads to the failure of casting and the waste of materials.
