Slurry-water phase interface movement tracking observation device and method under complex condition

Abstract

The invention relates to a slurry-water phase interface movement tracking observation device and a method under a complex condition. The observation device comprises a detachable test box body, a water injection pipeline, a slurry injection pipeline and a pressure release valve. The interior of the detachable test box body is configure to be the space for accumulating a crack rock body test piece, and comprise two oppositely arranged transparent side walls. The water injection pipeline is connected with the test box body and used for achieving pressure water injection. The slurry injection pipeline is connected with the test box body and used for achieving pressure slurry injection. The pressure release valve is arranged on the test box body. A first fluorescent powder charging device is arranged on the water injection pipeline. A second fluorescent powder charging device is arranged on the slurry injection pipeline. An ultraviolet ray emission device and a shooting device are respectively arranged on front and back sides which are perpendicular to the directions of the transparent side walls. According to the invention, the process of the slurry injection can be well known; the slurry injection theory is allowed to be well guide construction; and through the slurry injection process visualization and parameter monitoring, the general rule in the slurry injection process can be effectively researched.

Description

technical field [0001] The invention relates to the field of grouting simulation test equipment, in particular to a device and method for tracking and observing slurry-water phase interface movement under complex conditions. Background technique [0002] In the construction of underground engineering, engineering geological problems such as weak surrounding rock and inrush water are often encountered. These engineering geological problems and disasters will have adverse effects on construction. Grouting is a powerful way to strengthen weak surrounding rock and control inrush water disasters. means. Grouting is a comprehensive process involving multidisciplinary professional theories, but it is difficult to break through the semi-theoretical and semi-empirical state because of its concealment in the construction process and the complexity of engineering geological conditions.

Grouting is a comprehensive process involving multidisciplinary professional theories, but it is difficult to break through the semi-theoretical and semi-empirical state due to its concealment in the construction process and the complexity of engineering geological conditions

The current test method cannot effectively simulate the spatial distribution inhomogeneity of the rheological parameters of the grout, and cannot obtain the movement of the grout particles in the fracture network, so it is impossible to explore the general law of the grouting mechanism
