Experimental device for monitoring motion regularity of pipeline-fissure water flow

Abstract

The invention discloses an experimental device for monitoring the motion regularity of pipeline-fissure water flow, which mainly comprises a pipeline-fissure network-structured medium model, a water-pressure sensor system, a data-acquiring system and an image-acquiring system, wherein the water-pressure sensor system is used for measuring a whole flow field, the data-acquiring system is used for automatically reading data, and the image-acquiring system is used for capturing the motion regularity in real time. The pipeline-fissure network-structured medium model is characterized by comprising an organic glass plate with a clamping slot and an organic glass plate without the clamping slot, wherein organic glass blocks in different sizes are placed between the two glass plates to form a fissure network structure, and certain spaces are reserved at the left side and the bottom of a fissure network-structured medium to form a pipeline. The device has a reasonable structure and strong operability, and the fissure network structure can be conveniently adjusted. A pressure sensor system in a model device can be used for measuring water power conditions in the whole flow field and automatically reading the data. The motion regularity of the water flow in the whole flow field can be intuitively known in real time through the shooting technology of a high-definition video camera.

Description

technical field [0001] The invention relates to a visualization device for automatic monitoring of water flow movement rules in pipelines and fissure networks, and an experimental device capable of self-adjusting the size of pipelines and fissures, belonging to the technical field of groundwater detection. Background technique [0002] A large number of pipelines and fissure networks are developed in karst areas. Due to this special geological structure, the occurrence, distribution and migration of groundwater resources in karst areas are extremely complex, which brings difficulties to the study of groundwater flow laws. The movement of groundwater in the pipe-fracture medium can be roughly divided into two categories, one is the movement along the fracture network of the fracture medium, which is characterized by relatively dispersed water flow and good connectivity; the other is the flow along large fractures or pipes, It is characterized by concentrated distribution of w...
