A large-scale three-dimensional model test transportation device

Abstract

The invention discloses a large three-dimensional model test transport device including a model platform, a support base, a pedestal and a guide rail, wherein the model platform is laid on the pedestal, the guide rail comprises an upper guide rail and a lower guide rail, the model platform includes a model casting area, a model recurvature area, a casted model temporary storage area, an abandoned model temporary storage area and a model test area, the upper guide rail is provided with the support base, the lower guide rail is provided with a transport vehicle, and the model recurvature area is provided with a transport vehicle steering device. By reasonable allocation of three aspects of model casting, model test and model test treatment in a large three-dimensional model test, cyclic utilization of a high strength counterforce frame, a loading device and other model test infrastructures and alternate use of a test model can be realized, the test period can be greatly shortened and the test cost can be saved.

Description

technical field [0001] The invention relates to a large-scale three-dimensional model test transportation device. Background technique [0002] At present, the construction of underground projects such as long tunnels, subways, hydropower stations, iron mines, and coal mines is booming in China. However, many geological disasters such as water inrush, mud inrush, and landslides occur from time to time, causing a large number of casualties and economic losses. In order to study the causes of geological disasters and find ways to avoid such disasters, domestic and foreign scholars have carried out many three-dimensional mechanical model tests. In the existing three-dimensional model tests, because the researched test models are often under the condition of large buried depth, it is necessary to Loading devices, high-strength reaction frames and other components are used to provide confining pressure for the test model. These components are fixed on the foundation by high-stren...

AI Technical Summary

Problems solved by technology

This test method will produce two disadvantages: one is that the loading device, high-strength reaction force frame and other components are expensive, and if they are used for one time, it will cause great waste, and the test funds will not be used to the maximum extent; second, this method The replacement of the cast test model cannot be realized, that is, the preparatory work for each test takes several months, but only one model test can be carried out, which will greatly reduce work efficiency and increase the test cycle
