Problems solved by technology
[0008] (1) The existing constant-pressure grouting servo control system is suitable for indoor constant-pressure grouting tests, but cannot meet the requirements of constant-flow grouting tests
[0009] (2) The existing manual grouting pump meets the test requirements of small flow and high pressure, but the control accuracy of grouting flow and grouting pressure needs to be improved, and it is not suitable for fine grouting test
[0010] (3) The existing pneumatic grouting pumping device is suitable for indoor constant flow grouting test, but cannot meet the requirements of constant pressure grouting test
At present, there is no test device for precise control of grouting parameters such as grouting flow rate, grouting pressure and grouting volume

The invention discloses a slurry injection servo control device for an indoor slurry injection simulation test and an operation method. The device comprises a pressure supply unit, a slurry storage stirring unit and a measurement and control unit, wherein the slurry storage stirring unit comprises a chamber having an accommodation space, the chamber is internally provided with a multi-stage stirring mechanism, the chamber is provided with a slurry inlet channel and a slurry outlet channel, the pressure supply unit is used for providing servo control pressure for slurry accommodated in the slurry storage stirring unit, the measurement and control unit is connected with the pressure supply unit and the slurry storage stirring unit, and slurry injection servo closed loop control is realized through controlling the applying pressure and the flow velocity or the flow of the slurry inlet channel and the slurry outlet channel. The is advantaged in that measurement and control for slurry injection pressure are carried out through a servo control loading disc, the slurry injection flow and the slurry injection amount are measured and controlled through adjusting the volume of the slurry, and random switching servo control on the slurry injection pressure, the slurry injection flow and the slurry injection amount can be carried out.
Description
technical field [0001] A grouting servo control device and operation method for indoor grouting simulation test Background technique [0002] Grouting is an effective method for water inrush disaster control and stratum reinforcement in underground engineering. Due to the complexity of the engineering geological environment and the concealment of grouting construction, the law of grouting diffusion and reinforcement mechanism in complex strata is still unclear. At present, the indoor grouting simulation test is an important means to study the grouting diffusion reinforcement theory and grouting technology. [0003] The grouting device is used to control the grouting parameters of the indoor simulation test, which is one of the keys to ensure the refinement of the grouting test. At present, the indoor test grouting device is usually formed by assembling a grouting pump, an electromagnetic flowmeter, a pressure transmitter and a grouting pipeline. The representative groutin...
