Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of super-large three-dimensional physical model tests, and specifically relates to a transfer system. Background Art
[0002] At present, problems such as poor safety and great engineering difficulty have long plagued the use of in-situ test methods to study the formation mechanism of complex geological structures and extreme host environments in deep engineering projects of 10,000 meters, and the breeding mechanism of major disasters in deep engineering. Now, physical models of artificially configured three-dimensional similar materials are usually used to carry out relevant experiments under different boundary conditions. The theoretical basis of ultra-large physical model experiments is the principle of similarity. This method can effectively solve many problems of in-situ test methods.
[0003] The reliability of the loading structure is directly related to the accuracy and precision of the test, and thus to the credibility of the experimental data. The similarity ratio of existing test equipment is too large to truly reflect the complex geological structure information. At the same time, there are also the following problems:
[0004] The existing three-dimensional reaction frames are usually traditional prestressed structures in both horizontal and vertical directions, and usually adopt welded structures. Such structures are still acceptable for small-sized specimens below 2 meters, but cannot meet the test requirements of ultra-large three-dimensional physical model tests, such as tests of 10,000 tons or more.
[0005] The existing three-dimensional reaction frame is usually composed of two reaction frames, one of which provides horizontal reaction force and the other provides vertical reaction force. According to the layout form, it is divided into vertical and horizontal. Whether vertical or horizontal, in order to achieve the entry and exit of the specimen, it is usually necessary to move the frame horizontally or vertically. This technical solution is feasible for the loading structure of small-sized specimens below 2m, and the moving mass is usually small. However, when facing super-large loading structures, such as loading structures of more than 10,000 tons, the moving mass is usually thousands of tons, which poses a great safety risk.
[0006] The existing three-dimensional reaction force frame, whether vertical or horizontal, has a significant disadvantage. Due to structural limitations, a heavy-duty lifting device is usually required for the specimen to enter the loading position. The appearance of this device will bring great safety challenges to the entire equipment and low reliability. In the existing horizontal layout, in order to facilitate the entry and exit of the specimen, one end of the horizontal load-bearing frame usually needs to be opened. The horizontal load-bearing frame overcomes the loading reaction force through the column, and each test requires the fixing and removal of the column nuts. The removal of heavy nuts is labor-intensive and difficult to operate, and it is necessary to ensure that the prestress of many columns is consistent, which is a very delicate and time-consuming task.
[0007] The existing horizontal loading structure uses a sample transfer system to enter the loading structure, which is usually suitable for small-sized samples below 2m, but not for super-large loading structures. Because the samples used in super-large loading structure tests are usually hundreds of tons, the existing transfer system cannot withstand such heavy loads.
[0008] In summary, it is impossible to realize super-large loading structure based on existing technology, and it must be realized by using breakthrough innovative technology. Therefore, it is very necessary to develop a super-large three-dimensional physical model horizontal loading device. Utility Model Content
