Mould for manufacturing three-dimensional compound rock stratum circular tunnel and using method thereof

Abstract

The invention discloses a mould for manufacturing a three-dimensional compound rock stratum circular tunnel and a using method thereof. The mould comprises a square bottom plate, four baffles and a plurality of partition plates, and the baffles are fixed at the periphery of the bottom plate through bolts; the two sides of the baffles are each provided with a plurality of wedge grooves of two inclined angles; the center of the bottom plate is provided with a hollow cylinder, and the outer side of the hollow cylinder is provided with inserting grooves corresponding to the wedge grooves formed in the baffles; the partition plates are obliquely arranged on the bottom plate, and the two ends of each partition plate are inserted into the wedge grooves of every two adjacent baffles, or one end of each partition plate is inserted into the corresponding wedge groove, and the other end of the partition plate is inserted into the corresponding inserting groove. According to the mould, through cooperation of the wedge grooves formed in the baffles with the partition plates and the central cylinder, pouring of compound rock strata of space different inclined angles and different distances can be achieved; the rock stratum manufacturing effect is good, the inclined angles and space distances can be controlled precisely, the experimental difficulty and experimental errors are greatly reduced, and the experimental precision is improved.

Description

technical field [0001] The invention relates to the field of physical simulation experiments of similar materials in the discipline of geotechnical engineering, in particular to an experimental device for making a model of similar materials in composite rock formations. Background technique [0002] At present, in the field of similar simulation experiments, when making physical models of similar materials for composite rock formations, due to the limitations of ordinary experimental devices, it is difficult to pour composite rock formations with a certain inclination angle, and the experimental results are not ideal. Therefore, most of the similar material simulation experiments on composite rock formations only consider the composite rock formation with a dip angle of 0°. Contents of the invention [0003] The purpose of the present invention is to propose a mold for making a three-dimensional composite rock formation circular tunnel, which can prefabricate two kinds of ...
