Description

technical field [0001] The invention relates to the field of grouting simulation experimental equipment, in particular to a grouting experimental equipment. Background technique [0002] In the construction of civil engineering, we often encounter weak soil layers such as sand layers rich in water and poor bearing capacity. These weak layers have extremely adverse effects on engineering construction, and these soil layers need to be water-stopped and reinforced before construction. [0003] As an effective, convenient and low-cost geotechnical engineering technology, the grouting method is widely used in engineering construction. However, due to the complexity of the stratum conditions and the invisibility of the grouting method, the Theoretical research lags far behind engineering applications. Indoor simulated grouting test is an effective method to study grouting theory and engineering application. Model test has the characteristics of low cost, easy control, and intuiti...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a kind of grouting experiment equipment, which can effectively simulate the influence of actual formation soil pressure and pore water pressure, so that the indoor grouting test effect is close to the actual project, thereby solving the problem of existing laboratory grouting simulation. The small size of the model box cannot simulate the influence of the actual formation soil pressure and pore water pressure, and the simulation effect is very different from the actual project.
