Problems solved by technology

[0006] 1) The airtightness of the model bench is not good, so it is not suitable for similar model tests of solid-liquid coupling;
[0007] 2) The loading direction is single, and it is difficult to realize three-way loading
Most of the existing loading methods are to apply load on the top of the model without applying lateral load;
[0008] 3) Most of the existing similar simulation test benches are aimed at horizontal coal seams or near-horizontal coal seams
There are some shortcomings in these methods. First, enough space is required to suspend a test bench, and there are certain hidden dangers; second, more manpower and time are required for the physical similarity simulation experiments of coal seams with different inclination angles;
[0009] 4) The surrounding baffles of the model stand are not easy to disassemble, which brings a lot of inconvenience to the process of laying and removing materials

Embodiment Embodiment 1

[0120] By implementing Embodiment 1, it has the following advantages:

[0121] 1. Through the sealing of the front baffle, the left baffle, the right baffle and the back baffle and the periphery, the sealing performance of the three-dimensional similar model test bench is improved, and it can be applied to the similar model test of solid-liquid coupling.

[0122] 2. The three-way loading of the model is realized through the left loading unit, right loading unit and top loading unit.

[0123] 3. Push the rolling multi-directional loading platform to rotate and maintain it through the limit roller, which can conveniently simulate inclined coal and rock formations at will, and achieve the purpose of safety and reliability during the laying process.

[0124] 4. The left baffle, the right baffle and the back baffle are stacked layer by layer through multiple bars, which are easy to disassemble.

[0125] 5. By arranging the lateral loading system inside the left and right sides of ...

Abstract

The invention discloses a three-dimensional similar model test stand, which includes a rolling type multidirectional loading stand and limit rolling instruments. The rolling type multidirectional loading stand consists of a barrel-shape frame, a front baffle plate, a back baffle plate, a left baffle plate, a right baffle plate, a left loading unit, a right loading unit and a top loading unit. Thebarrel-shape frame includes a hollow housing with a cylindrical outer surface, the top surface, the front and the back of the housing are hollowed-out, the barrel-shape frame also includes a bottom plate, the bottom plate is installed at the bottom inside the housing, the front baffle plate is installed at the front of the housing, the back baffle plate is mounted at the back of the housing, the left baffle plate is installed on the left inside the housing, the right baffle plate is installed on the right inside the housing, the left loading unit is mounted between the housing and the left baffle plate, the right loading unit is mounted between the housing and the right baffle plate, and the top loading unit is used for loading at the top of the model. The limit rolling instruments are used for promoting the rolling type multidirectional loading stand to roll back and forth to set angle, and can stay at corresponding positions.

Description

technical field [0001] The invention relates to the field of similar simulation tests, in particular to a three-dimensional similar model test bench and a test method thereof. Background technique [0002] The similar simulation test was proposed by Kuznetsov of the former Soviet Union in the 1930s. And it is used in Quansu Mine Survey and Coal Research Institute. It is also widely used in Germany, Poland, Japan, Australia, and the United States. Up to now, it has become an important research method in the foreign mining industry. In 1958, my country took the lead in establishing a similar simulation test frame in the mine pressure laboratory of China University of Mining and Technology, and gradually expanded it to the Coal Science Research Institute, coal universities, metallurgy, construction, water conservancy, engineering geology and other departments. The application of similar material physical simulation technology in China in the 1950s and 1960s was mainly based ...
