Abstract

The invention relates to a small block model pressing equipment for simulating a rock mass structure, and belongs to the technical field of a geomechnical model test. the equipment comprises a frame base, and a small block mold, an upper mold ejection block, a push-pull cover board, a pressure lever and a range draw bar which are fixed on the frame base; the small block mold and the push-pull cover board are arranged at the upper surface of the frame base; the upper mold ejection block is arranged at the lower part of the small block mold; the upper end surface of the upper mold ejection block is inserted into a cavity of the small block mold for simulating a rock mass; and the range draw bar is arranged at one end of the pressure lever. By adopting the small block model pressing equipment, the fabrication speed of a small block model can be greatly fastened; the quality of the small block model is improved; manpower and material resources are saved; meanwhile, the size, the shape and the height of a small block can be adjusted according to the requirements; and the smooth execution of the geomechnical model test is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of geomechanics model tests, and in particular relates to fine and fast pressing equipment for small block models used for simulating rock mass structures. Background technique [0002] Geomechanical model tests can simulate the characteristics of geotechnical engineering structures, and can also approximate the influence of geological factors such as rock mass faults on engineering stability. It plays an extremely important role in the design of rock engineering such as water conservancy, mining, and tunnels It has been widely used. For example, the large and medium-sized arch dams in my country have basically done geomechanical model tests. [0003] According to the requirements of the similarity rate of the model test, the geomechanics model test has relatively high requirements on the mechanical properties of similar materials for simulating the dam body and the surrounding foundation rock mass. The Wate...
