Embodiment
[0041] (1) Model assembly: first determine the orientation of the baffle groove according to the inclination angle of the required rock formation, then place the bottom plate of the model flat on the level ground, and connect the four baffles to the bottom plate through bolts in turn according to the determined orientation; Determine the length of the required baffles according to the spacing of the required rock formations, select the corresponding length of the baffles, and form different rock layer pouring zones through the insertion of the ends of the baffles and the grooves of the baffles; especially note that when the baffles When it is necessary to pass through the central cylinder, one end of the partition is required to be inserted into the groove on the surface of the cylinder to form an excavation tunnel;
[0042] (2) Pouring of composite rock formations: The pouring of composite rock formations is completed in sequence according to the layout of the pouring belt. Af...

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 ...
