A method for manufacturing a simulation tunnel deformation experiment model

Abstract

Provided is a method for manufacturing a simulation tunnel deformation experiment model. The position of a simulation tunnel is arranged at the central section of a model case, and simulation tunnel components of set dimensions are placed. Boards with a plurality of anchor pole component holes are respectively arranged in the left and right sides and the top portion positions of the simulation tunnel components. Anchor pole components with hooks at the head portions are inserted from the bottom portions of the boards with the plurality of anchor pole component holes in the left and right sides to the board with the holes at the top portion. At the same time, simulation materials are filled into the model case until the model case is full of the filled simulation materials, and the simulation materials are compacted tightly. After the filled simulation materials are molded, the simulation tunnel components are extracted, and the boards are taken away, the manufacturing of simulation tunnel model is completed. Through the dimensions of the tunnel components and the size of the boards, the size of tunnels in the model can be controlled. Through the thicknesses of the boards, the exposed lengths of the anchor pole components can be controlled. Through the adjusting of the positions of the holes in the boards, the mode of arrangement of the anchor pole components can be changed.

Description

technical field [0001] The invention relates to a method for preparing an experimental model for simulating roadway deformation, and is especially suitable for similar simulation tests related to roadway bolt support in laboratories. Background technique [0002] The use of similar simulation is an effective method for studying the laws of roadway deformation, movement and failure, especially for rock mechanics problems involving elastoplasticity, crushing, caving, etc., and multiple physical and mechanical processes with various forms of cavity structures. method. Through the simulation study of the interaction between the bolt and the surrounding rock, the relationship between the force of the bolt and the activity of the overlying strata can be found, and the effect of changing a certain support parameter on the deformation of the roadway can also be found through the analogy test of several models. law. [0003] In traditional similar simulation experiments, there are ...

AI Technical Summary

Problems solved by technology

The traditional method of pre-embedded anchor elements cannot accurately locate the anchor elements. During the model laying process, the anchor elements often move and deviate from the designed position, and the anchor elements cannot be exposed for a certain length

If the anchor element is applied after the roadway is formed, holes must be drilled in the roadway. Due to the limitation of the size of the model, it is very inconvenient to punch holes, which greatly increases the workload of model laying, and will cause the roadway wall to be uneven. It is easy to form local stress concentration in the process
