Problems solved by technology

[0005] However, the prominent problems in current research are: (1) Many grouting diffusion theories lack systematic research on the determination of grout flow pattern
(3) There are many contradictions in the current research on slurry flow pattern and rheological parameter time-varying
In other words, there is a possibility of re-grouting some time after the pumpable period of the grout

Embodiment Construction

[0018] The grouting diffusion test device of the present invention will be further described in detail below in conjunction with specific implementation methods and accompanying drawings.

[0019] figure 1 It is a working principle diagram of a specific embodiment of the grouting diffusion testing device of the present invention. In the figure, the grouting diffusion test device includes a test fluid generation device 1, a slurry diffusion test device 2 and a recovery device 3, and the test fluid generation device 1 includes a water flow pressurizer 11 and a slurry pressurizer 12 to generate pressurized water and grouting slurry According to the designed dynamic water flow rate, grouting pressure, and grouting amount, the experimental substance is supplied to the slurry diffusion test device 2 through the pressure water delivery hose 13 and the slurry delivery hose 14 . The water flow pressurizer 11 and the pressure water delivery hose 13 constitute a water flow generating de...

Abstract

The invention relates to a slurry disperse tester, which comprises: a testing fluid generator, a slurry disperse tester, and a recycle device, wherein the testing fluid generator generates the slurry, to feed testing material to the slurry disperse tester via the slurry pressure and slurry amount; the slurry can disperse in any simulated seams in the slurry disperse tester; the slurry disperse tester has the window for watching the slurry dispersed shape and the disperse edge, and the fluid pressure tester for reading out the energy consumption in different disperse distance; the recycle device can recycle the slurry. The invention can simulate different seams and geological conditions, to confirm different pressure and amount.

Description

technical field [0001] The invention relates to a grouting diffusion testing device. Background technique [0002] Due to the complexity of the geological conditions of the rock mass and the concealment of the grouting project, it is difficult for people to control the grouting effect, such as the spread of the grout, the anti-seepage or reinforcement effect of the grouting, but only from the apparent effect and local The detection results reverse the situation in grouting. Therefore, people have always hoped to establish a grouting diffusion model, using limited known conditions to predict the grouting range. [0003] However, it is impossible to establish a theory of grouting diffusion that applies to all projects. Although a lot of literature is devoted to establishing a model capable of predicting the diffusion range of fracture grouting and deriving the formula of diffusion radius, various geological conditions, such as fracture opening, seepage properties, fracture ...
