Pouring mold for manufacturing rock mass sample containing tunnel and joint model

Abstract

The invention discloses a pouring mold for manufacturing a rock mass sample containing a tunnel and joint model, which comprises a mold main body, a joint and tunnel simulation device is arranged in the mold main body, and a fixing system of the joint and tunnel simulation device is arranged on the joint and tunnel simulation device; the fixing system of the tunnel simulation device comprises an inner bottom plate and an upper top plate, tunnel bayonets are arranged in the middle of the inner bottom plate and the middle of the upper top plate, and a plurality of joint clamping grooves are formed in the positions, around the tunnel bayonets, of the inner bottom plate and the upper top plate. The joint and tunnel simulation device comprises a plurality of joint models and tunnel models located in the middle of the joint models, the upper ends and the lower ends of the joint models are embedded into corresponding joint clamping grooves in the inner bottom plate and the upper top plate correspondingly, and the upper ends and the lower ends of the tunnel models are embedded into tunnel bayonets in the inner bottom plate and the upper top plate correspondingly; the size of the prepared sample is more accurate, so that the sample preparation process is more time-saving, labor-saving and more convenient, and the workload of a user is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of rock mass mechanical test and rock-like materials, in particular to a rock mass sample casting mould used for making tunnel and joint models. Background technique [0002] With the rapid development of urban rail transit, my country's urban rail transit, construction engineering, underground space engineering, bridge and tunnel engineering, mineral resources exploration and development, transportation and other projects have been constructed on a large scale. Rock mass is the most common complex engineering medium in these civil works, and its strength and deformation characteristics play a crucial role in the construction of these civil works. For example, after a tunnel is excavated, the performance of the surrounding rock mass in a certain range to resist deformation and damage will directly affect the overall safety and stability of the tunnel. In-depth research on the mechanical properties of rock m...

AI Technical Summary

Problems solved by technology

[0005] Due to the discontinuity, anisotropy, inhomogeneity and brittleness of the rock mass itself, it is very difficult to sample rock mass materials, and it is difficult for people to obtain rock mass samples whose integrity and mechanical properties are not disturbed.
