Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] Such as figure 1 , 2 As shown, a method and equipment for making a three-dimensional cavity model for a real three-dimensional model test.

[0036] Production Method The steps are:

[0037] 1) Make a wax model (wax model) 1 that is consistent with the size of the proposed cavity, and preset heating rods and catheters 5 in its body;

[0038] 2) Wrap the wax model 1 in the milk capsule 2.

[0039] 3) Laying similar materials in the model reaction frame 9 to press the three-dimensional similar material model 8 . When the model body 8 is filled to the bottom of the cavity, the wax model 1 wrapped with milk capsules is placed in the corresponding position of the proposed cavity;

[0040] 4) Lay model-like materials around the wax model 1, continue to press the three-dimensional model 8 until the wax model 1 is completely placed in the entire th...

Abstract

The invention relates to a molding method and apparatus of a three-dimensional cavity model for a true three-dimensional model test. The cavity molding adopts a molding method that an internal wax model is melted and a liquid is extracted. The specific method is as follows: a wax model with the same size as that of a cavity to be molded is produced, and a heating rod and a liquid guide pipe are pre-arranged in the wax model; the wax model is wrapped in an emulsion capsule; the wax model with the emulsion capsule wrapped outside is placed at a corresponding position of the cavity to be molded,and a pre-reserved hole is arranged at the top of the cavity; the heating rod is electrified, so that the wax model is gradually melted and a wax liquid is extracted from the model; and the heating rod and the liquid guide pipe are sequentially taken out of the emulsion capsule through the pre-reserved hole, and then the pre-reserved hole is closed by a similar material, so that the model is finally molded. By the method, the three-dimensional cavity 3D (three dimensional) geomechanical model with an accurate size, a precise position, and a shape in line with the actual project is finally manufactured. The method has the advantages of high efficiency, fastness, economy, simpleness in operation of equipment, fast cavity molding speed and the like.

Description

technical field [0001] The invention relates to a method and device for forming a three-dimensional cavity model for real three-dimensional model testing. Background technique [0002] With the vigorous development of underground resource development, underground structures have been widely used in the fields of hydropower, transportation, resources, and energy. At the same time, the construction safety of underground caverns has also received more and more attention and attention. With the deepening of underground engineering and the improvement of project scale, the engineering geological conditions and hydrogeological conditions of the rock mass in the proposed underground engineering area are becoming more and more complex. Three-dimensional geomechanics model experiments are used to analyze and evaluate the stability of surrounding rocks excavated in underground caverns, so as to effectively reveal the mechanical characteristics and deformation and failure laws of surro...
