Abstract

The embodiment of the invention discloses a grouting diffusion test system and method. The system comprises a grouting diffusion test device, an image acquisition device and a data processing device,wherein the image acquisition device is used for acquiring image information in the grouting diffusion process in real time, processing and identifying the image information, calculating key diffusionparameter information which is timely and accurate in the diffusion process, drawing dynamic three-dimensional slurry diffusion animation in real time, directly acquiring a diffusion graph at a certain time point from the three-dimensional slurry diffusion animation without processing a recorded video, and carrying out subsequent diffusion research. The system has the advantages of high data acquisition precision, high result accuracy, simple and quick operation and effective labor and material saving.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of grouting engineering, in particular to a grouting diffusion test system and method. Background technique [0002] In order to realize the control of the grouting effect in the grouting project, the grouting diffusion parameters are calculated through the grouting diffusion simulation experiment, and a variety of grouting diffusion models are established to simulate and study the grouting diffusion process under different geological conditions. Traditionally, the whole process of the grout diffusion experiment is monitored through video recording, and then after the experiment is completed, the grout diffusion graph is manually drawn according to the experimental video to observe the grouting simulation process. This processing method wastes a lot of time and the accuracy of data collection is greatly affected. In addition, the video processing process is complex and difficult, an...
