Embodiment Construction

[0033] A method of measuring a flow vector of a seepage liquid, the method comprising the steps of:

[0034] 1) Select the rock 9 for the test;

[0035] 2) Select a plurality of observation points 8 at different positions (i.e. arbitrary target positions) on the cracked surface 1 of the rock 9;

[0036] 3) Arrange paints on each observation point 8, and the colors of the paints on adjacent observation points 8 are different;

[0037] 4) Make the transparent opposite model 10 of the rock crack surface 1, the transparent opposite model is made of resin material, and the manufacturing method is made according to the technical scheme disclosed in Chinese Patent Application No. 201510017229.0;

[0038] 5) Put the transparent antithesis model 10 on the cracked surface 1 of the rock so that the cracked surface 1 of the two completely coincides, as figure 2 As shown, the edges of the transparent opposite model 10 and the rock 9 are respectively provided with relative water inlets 6...

Abstract

Provided is a method for measuring the flow vector of seepage liquid. The method includes the following steps that 1, rock is selected; 2, observation points are selected; 3, pigment is arranged on the observation points; 4, a transparent opposite face model of a rock fracture face is made; 5, the transparent opposite face model is arranged on the rock fracture face; 6, transparent sulfuric acid grid paper is placed on the upper surface of the transparent opposite face model; 7, a camera device is installed; 8, water injection is performed till seepage occurs; 9, multiple flow path lines with colors appear; 10, flow conditions are recorded; 11, a shot image is analyzed, the seepage speed of any point at the minimum time difference is calculated, and then the seepage vector of any point of the fracture face at any micro time period is measured. By means of the method for measuring the flow vector of the seepage liquid, the problem that it is impossible to trace the seepage direction of any point and calculate the seepage speed can be solved, the instant flow speed of liquid at any point in a fracture joint face can be measured, and measurement precision is high.

Description

technical field [0001] The invention relates to the technical field of rock and soil seepage, in particular to a method for measuring the flow vector of seepage liquid. Background technique [0002] The existing tracer technology (name: a visual rock seepage monitoring device, patent number: 201410352339.8) observes the seepage through uniform coloring of the seepage liquid. This technology cannot trace the seepage direction at any point on the crack surface. It is not possible to measure the seepage velocity at any point at a given moment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for measuring the flow vector of seepage liquid, which can solve the problem that the seepage direction of any point cannot be traced and the seepage velocity can be measured, and realize the measurement of the instantaneous flow velocity of liquid at any point in the crack joint surface , high measurement accuracy. ...
