Problems solved by technology
[0011] The purpose of the present invention is to solve the technical problem that the large block model cannot be produced quickly, accurately and with high quality in the geological model test, and provides a block model pressing equipment for simulating the rock mass structure. The present invention can greatly speed up the production of the block model The production speed saves a lot of manpower, material resources and time; and the size, shape and height of the block can be adjusted accurately in a relatively large range according to the needs, thereby reducing the amount of small blocks and shortening the test period. Better meet the needs of various masonry schemes for geological model tests and ensure the smooth progress of the tests

The invention relates to pressing equipment and method for a rock mass structure simulated block model. A pneumatic jack (2) is arranged at the bottom of a supporting framework (1); an automatic control valve (7) controls up-and-down movement of a piston in the pneumatic jack (2); a die jacking component (4) is arranged on the pneumatic jack (2) and is driven to move up and down; the die jacking component (4) is located at the lower part of a block die (5), a mixture in the block die (5) can be compacted along with the movement of the die jacking component (4), and a formed block model can be pushed out; a horizontal feeler lever (3) is mounted on the die jacking component (4), limiting regulation members (6) are fixed at middle positions of the supporting framework (1), and the height of the block model is controlled through setting the height of the horizontal feeler lever (3) and the height of the limiting regulation members (6). According to the equipment and the method, large block models can be pressed, manual pressing is not required, labor load is reduced, and the efficiency of block pressing is increased.
Description
technical field [0001] The invention relates to the technical field of geomechanics model tests, in particular to a block model pressing device and method for simulating rock mass structure. Background technique [0002] Geomechanical model tests are widely used in the design of rock engineering such as water conservancy, mining, and tunnels. Based on a certain similarity principle, a specific engineering structure and its existing geological environment are simulated in scale. These geomechanical model tests can not only simulate the characteristics of geotechnical engineering structures, but also approximate the influence of geological factors such as rock mass faults on engineering stability, which has important guiding significance for the design and construction of rock mass engineering. Most large and medium-sized arch dams have basically undergone geomechanical model tests. [0003] In order to meet the similar conditions, the geomechanics model test has relatively h...
