Description

technical field [0001] The invention relates to an intelligent monitoring and control system and a monitoring and control method for grouting fluid parameters in the infiltration grouting process, belonging to the technical field of geotechnical engineering. Background technique [0002] Grouting technology is to use hydraulic, pneumatic or electrochemical principles to inject grout into the formation through grouting drilling or placing grouting pipes. The grout is filled, infiltrated, compacted or split. After driving away the moisture and air between the rock and soil particles or in the rock cracks, it occupies its spatial position. After a certain period of time, the grout coagulates and hardens to form a concretion or gel with a relatively complete structure, high waterproof and impermeable performance, and good chemical stability. body; and cement the original loose rock-soil particles or cracks into a whole to achieve the purpose of improving the physical and mechani...

Problems solved by technology

At present, scholars at home and abroad have developed some infiltration grouting process parameter monitoring devices. For example, Chinese patent CN 105136195 A introduces a porous media infiltration grouting multi-parameter monitoring device and its test method, which can monitor the pressure, density, Temperature and flow rate parameters; however, these devices monitor the changes in the permeation and migration parameters of the grout in porous media, and they are quite different from the actual engineering conditions of grouting

[0005] To sum up, the existing penetration test device does not consider the dynamic changes of the grouting fluid parameters (such as density, flow rate, temperature and viscosity, etc.) that diffuse and flow in the grouting pipeline during the entire infiltration grouting process. ; However, changes in these parameters of the grouting fluid have a very important impact on the size and effect of permeation grouting diffusion
