Abstract

The invention provides a three-dimensional visual multifunctional grouting test model device. The three-dimensional visual multifunctional grouting test model device comprises a test module and is characterized in that the test module is of a cuboid-like structure formed by a top cover, a top cover sealing ring, a tempered glass box, a grouting pipe, a bottom plate, a bottom plate sealing ring, abottom support and bottom ribbons, the steel top cover, the tempered glass box and the tempered glass bottom plate are connected through high-strength bolts, grout diffusion conditions during groutingcan be favorably observed dynamically through the transparent tempered glass, a water injecting pipe is reserved at the center of the top cover, and the front side of the box is provided with a grouting pipe. The device has the advantages that the device can be used for simulating grouting under water-free, still-water, flowing-water and high-pressure-water environments; in addition, the device is creatively provided with the bottom ribbons, and the ribbons can be removed step by step according to test needs so as to analyze the stratum stability change conditions before and after the grouting.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, in particular to a three-dimensional visualized multifunctional grouting test model device. Background technique [0002] In recent years, with the rapid development of my country's national economy, more and more attention has been paid to the development and utilization of urban underground space. More and more cities have planned and built a large number of underground engineering facilities such as underground railways, municipal tunnels, and underground stations. In most urban underground projects, there will be situations such as loose granular matter at the bottom, water and mud inrush, etc., which will lead to instability of the surrounding rock after excavation. Grouting is to prepare a certain material into a slurry, and use pressure feeding equipment to pour it into the formation or gap to make it diffuse, gel or solidify, so as to achieve the purpose of strengthening the form...
