Problems solved by technology

The common defect of these models is that in order to meet the measurement requirements, the prototype has to be rotated in different degrees in the geodetic coordinates. Therefore, it can only simulate the impermeable boundary or the uneven layer interface with regular shape and simple dam structure, which cannot Use it to study a large number of three-dimensional seepage fields of dams with complex geometric shapes and internal structures

Embodiment Construction

[0028] 1) Construct the terrain shape grid ① (made of wooden boards) the upper part is cut according to the topographical coordinates, and the lower part takes the unified base coordinates. After drawing grooves in the upper part of the longitudinal grating and the lower part of the horizontal grating respectively, the vertical and horizontal gratings are inserted into the grooves to form an overall grid terrain grating; the topography covering the terrain grating ② Select insulating soft cloth material , After soaking in epoxy resin solution, cover the topographic grid. When covering, the surface of each grid should be flat and smooth to prevent the resin liquid from accumulating in the concave area.

[0029] 2) The liquid barrier ③ is made of about 5mm plexiglass plate, on which the plum blossom-shaped holes with a diameter of 1mm are drilled at a certain density, and conductive copper wires are embedded in the holes, and the two ends are flush with the surface of the plexig...

Abstract

The invention relates to a method for manufacturing a conducting solution simulation test model for studying a three-dimensional seepage field of a dam, which is characterized in that the conducting solution simulation test model integrates the terrain, the dam structure, the measuring point and other arrangements into a whole and can meet the test requirement without rotating and cutting a prototype. The conducting solution simulation test model is used for point testing and three-dimensional seepage surface arranging and overcomes the defects that a traditional model needs to penetrate through an internal structure to collect information on the elevation and the potential of the seepage surface; a seepage preventing ring made of strip-shaped watertight soft material ensures that the conducting solution of the conducting solution simulation test model can not seep and an electric field of the conducting solution simulation test model is undistorted; and the conducting solution simulation test model is made of conventional material, is strongly intuitive in appearance and is convenient for test, measurement and repair.

Description

technical field [0001] The invention relates to a method for making a conductive liquid test model, in particular to a method for making a conductive liquid test model for research on three-dimensional seepage fields of embankments. Background technique [0002] Using conductive liquid simulation technology to study the three-dimensional seepage field of dams is one of the basic methods commonly used. In the past, due to the limitations of model materials, manufacturing methods, and measurement techniques, the test model was fabricated by inversion, division, and tilting to facilitate the arrangement of measurement points and data collection. The common defect of these models is that in order to meet the measurement requirements, the prototype has to be rotated in different degrees in the geodetic coordinates. Therefore, it can only simulate the impermeable boundary or the uneven layer interface with regular shape and simple dam structure, which cannot be simulated. It is u...
