Abstract

The invention provides observation equipment for the microscopic features of rock fracture seepage based on a 3D (three-dimensional) printing technology. According to the observation equipment, firstly, a transparent resin material is adopted to be subjected to 3D printing so as to obtain a test sample required by the experiment; a servo motor controller, flowmeters and electromagnetic valves areconnected to a control mainboard through circuits so as to form a servo loop; the servo loop performs reading according to the flowmeters, the control mainboard controls opening and closing of the corresponding electromagnetic valves, so that the flowmeters with proper measuring ranges are selected to display the flow, and meanwhile, the control mainboard collects data of the flowmeters; when theflow shown by the flowmeters does not meet the requirements, the control mainboard sends a signal to the servo motor controller, the servo motor controller controls a servo motor to change the rotating speed of a water suction pump, so that the water supply amount is increased or decreased, and the flow can meet the experiment requirements; and the control mainboard automatically collects the datasuch as the pressure difference and the flow in the experiment process, and a PIV (particle image velocimetry) and nuclear magnetic resonance technology is adopted to observe and record the microscopic features of the movement of the seepage in a rock fracture network.

Description

technical field [0001] The invention relates to the field of rock mass fissure network seepage observation, in particular to a rock mass fissure seepage microscopic feature observation device based on 3D printing technology. Background technique [0002] Seepage in rock mass fissures has a very important impact on geotechnical engineering, mainly manifested in the impact of seepage on the physical, chemical and mechanical properties of rock mass. Therefore, it is of great significance to observe seepage in fracture network of rock mass. The existing rock mass fissure seepage test equipment usually still uses rock specimens, which can only measure the permeability coefficient of the rock mass fissure network, and cannot directly observe the flow of seepage in the rock mass fissures, and cannot analyze the rock mass fissures from a microscopic perspective. seepage characteristics. [0003] The invention provides a rock mass fissure network seepage microscopic feature observa...
