Abstract

The invention relates to a manufacturing die for multi-angle sandwich rock mass reinforcing test. The manufacturing die aims at effectively solving the problems of improving of integral stability of the member, higher strength and deformation ability, and saving of labor and materials in the multi-angle sandwich rock mass and anchor rod reinforcing technology. The manufacturing die is characterized in that a front steel plate, a back steel plate, a left steel plate and a right steel plate are arranged on a bottom plate to form an oblong-shaped groove; the upper end of the oblong-shaped grooveis provided with a plurality of pairs of groove openings; a blocking plate is arranged in any pair of groove openings and extends into the oblong-shaped groove; a plurality of pairs of reserved anchorrod holes are formed in the side walls of the oblong-shaped groove, a PVC (polyvinyl chloride) pipe is arranged in any pair of reserved anchor rod holes, and the middle part of each PVC pipe penetrates through a center hole in the corresponding blocking plate. The manufacturing die has the advantages that the better strength, rigidity, stability and other mechanical properties are realized; the deformation of a specimen in the casting process is avoided, and the integrity of the specimen is improved.

Description

technical field [0001] The invention relates to the technical field of rock and soil mechanics tests, in particular to a mold for making multi-angle rock mass reinforcement tests with interlayers. Background technique [0002] In geotechnical engineering and underground engineering, due to the characteristics of weak and broken surrounding rock, low strength, poor self-supporting force and difficult control of stability, it is one of the important factors affecting the stability of rock mass and the safety of buildings. The accidents of many engineering projects are mostly caused by weak interlayers of rock mass or insufficient strength of weak structural planes. However, in actual work, it is impossible to directly observe the development trend and failure form of cracks around the rock mass. Through experimental simulation, the failure characteristics and failure methods of rocks are analyzed, and the development trend and influence of micro-cracks inside rocks are explor...
