Small block model pressing equipment for simulating rock mass structure

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 testing, and particularly relates to a fine and fast pressing device used for simulating a small block model of a rock mass structure. Background technique [0002] The geomechanics model test can simulate the characteristics of geotechnical engineering structure and approximately simulate 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. For example, my country’s large and medium-sized arch dams have basically undergone geomechanical model tests. [0003] According to the similarity rate requirements of the model test, the geomechanical model test has relatively high requirements for the mechanical properties of similar materials that simulate the dam body and the surrounding foundation rock mass.

Problems solved by technology

However, a model test often requires tens of thousands or even more than 100,000 small block models, and the drying of each small block model after pouring is a huge amount of work, time-consuming and labor-intensive; The different volume parameters, that is, the production parameters such as the proportion of the small block model are different; and the shape and size of the small block production mold are single, which greatly restricts the test progress and technical development of the geomechanics model test.
