Automatic laying device for similar material simulation test and application method thereof

Abstract

The invention discloses an automatic laying device for a similar material simulation test. The automatic laying device comprises a weighing hopper, a stirrer, an elevation type belt conveyor, a similar material test chamber and multiple material bins. Discharging openings of the multiple material bins are connected with a feeding opening of the weighing hopper. A discharging opening of the weighing hopper is connected with a feeding opening of the stirrer. The automatic laying device has the beneficial effects that a series of technological improvement is conducted based on the laying and tamping method adopted in the similar material model production process; by means of the weighing hopper and the stirrer, all materials are mixed and stirred according to certain ratios, and molding quality of a similar material model is greatly improved; after stirring, the materials are conveyed into the similar material test chamber through the belt conveyor and then compacted through pressing plates; and labor intensity is lowered, in addition, the molding speed of the similar material model can be remarkably increased, the molding quality of the similar material model can be remarkably improved, and consistency of the similitude ratio of the simulation stratum thickness to strength obtained after molding can be remarkably improved.

Description

technical field [0001] The invention relates to a simulation test equipment, in particular to an automatic paving device for similar material simulation tests and a method for using the same. Background technique [0002] Due to the complexity of the underground engineering environment and the constraints that it is difficult to conduct on-site research, similar simulation tests have become an important scientific research method to realize the reproduction of such complex engineering environments such as geotechnical, geological, and mines. Based on the similar simulation theory and different research purposes, through similar simulation experiments on rock formations, chambers, dams, slopes and lanes (tunnels) and other research contents, relevant technical parameters can be obtained, providing a basis for practical engineering applications. in accordance with. [0003] At present, similar simulation tests mainly rely on manual completion during the model paving process. ...

AI Technical Summary

Problems solved by technology

For similar material models with larger volumes, the workload of weighing, mixing, laying and compacting the materials is huge, especially under the same geological conditions, the workload is doubled for the research of different mining conditions. If it is done manually This series of work is not only labor-intensive, but also due to the lack of experience of the paving personnel, the mixing is uneven, the degree of compaction is large and uneven, and the final test results are highly discrete, which makes the reliability of the results low.
