However, the infrastructure construction of wind farms faces many challenges, among which the stability of the foundation is one of the key factors to ensure the safe and efficient operation of wind turbines. Since wind turbines are subject to a variety of complex loads during operation, this places high demands on the bearing capacity, deformation resistance and stability of the foundation.

During the installation of the storage tank 4, a level is used to ensure that the level of the tank body is within the allowable error range, and the error does not exceed ±0.5°. When the humidity sensor and temperature sensor are installed inside the storage tank 4, the humidity sensor adopts a polymer capacitive sensor, and its probe is fixed on the inner side of the tank wall through a threaded connection, and the signal transmission line is led out through a sealed threading hole and connected to the control system. The thermocouple probe of the temperature sensor is inserted into the tank body, and insulation and sealing treatment are done to ensure the accuracy of the measurement. According to the data fed back by the sensor, when the humidity exceeds the set upper limit, the control system starts the ventilation equipment to reduce the humidity; when the temperature exceeds the range, the temperature is adjusted by the heating belt or the cooling circulating water pipe. When the precise metering equipment is installed, the spiral shaft of the spiral electronic scale 6 is connected to the motor 5 through a coupling. During the installation process, a dial indicator is used to calibrate the coaxiality of the spiral shaft to ensure that the coaxiality error is less than 0.1mm. When the inlet and outlet pipes of the chemical additive metering pump are connected, stainless steel clamps and sealing rubber rings are used to connect to ensure that the connection is firm and well sealed. When calibrating the metering pump, a high-precision measuring cylinder and a stopwatch are used to measure the actual flow rate under different pressures and flows. By comparing the set flow value with the actual measured flow value, the parameters of the metering pump are adjusted, the flow coefficient and index are determined, and the flow control accuracy is guaranteed to be within ±0.5%. The stirring blades of the mixing and stirring equipment are installed on the stirring shaft, and the stirring shaft is fixed to the top of the stirring tank through the bearing seat. When the forward action balance test of the installed blades is carried out, the blades are tested and corrected by a special dynamic balancing machine to ensure that the unbalanced amount is less than the specified value when rotating at high speed. When the stirring motor is connected to the control system, the speed control is realized by the frequency converter. The grouting pump 7 is installed on the shock-absorbing base, and the shock-absorbing base adopts a combination of rubber shock-absorbing pads and spring shock absorbers.

The installation direction of the flow sensor is consistent with the flow direction of the fluid, and its signal output line is connected to the grouting system.

[0022] The grouting system includes: The raw slurry preparation module mixes and prepares composite material slurry according to the geological conditions of the wind farm; Intelligent control module, real-time monitoring of system operating parameters and automatic regulation of each module operation; The grouting pumping module outputs slurry stably according to the preset grouting scheme and the instructions of the intelligent control module; Positioning module, using the positioning instrument to accurately position the grouting equipment; The raw pulp preparation module includes: A material storage unit for storing raw materials for preparing slurry; The mixing and stirring unit continuously stirs the prepared slurry and monitors the slurry quality in real time; Precise metering unit, using spiral electronic scale 6 to control the slurry flow; The mixing and stirring unit uses an online viscosity monitor to monitor the slurry viscosity in real time. The monitor measures the rotational torque of the rotor in the slurry. , to calculate the viscosity , when the viscosity deviates from the set range, the stirring blade speed is automatically adjusted; Specifically, the slurry storage tank 4 is installed on a stable foundation and equipped with a well-sealed feed port and a discharge port. A humidity sensor and a temperature sensor are installed inside the storage tank 4. The humidity sensor adopts a polymer capacitive sensor, and its principle is to measure humidity based on the change in capacitance after the polymer film absorbs water. The temperature sensor uses the thermoelectric effect of the thermocouple to determine the temperature by measuring the thermoelectric potential at both ends of the thermocouple. The humidity upper limit is set by the control system. , the temperature range is When the humidity or temperature exceeds the set range, the ventilation and dehumidification device is automatically started. When the system receives the grouting instruction, it accurately measures the raw materials according to the preset composite material ratio scheme, and the slurry is measured and transported through the spiral electronic scale 6. The motor 5 of the spiral electronic scale 6 adjusts the speed according to the command of the control system. The speed formula is: in, is the motor speed, is the speed adjustment factor, is the required slurry mass, is the slurry density, The volume flow of the spiral blades. Chemical additives are delivered by a high-precision liquid metering pump, which works according to the flow value and pressure value set by the control system. Flow control is achieved by adjusting the motor frequency or the stroke length of the pump, and pressure control is achieved by adjusting the valve opening at the pump outlet. Fiber-reinforced materials are metered and added through an automatic feeder. The metering accuracy of the feeder is controlled by adjusting the speed and outlet opening of the feeder. The metering model is established based on the density, diameter and length parameters of the fiber: in, is the fiber quality, is the measurement correction factor, is the fiber density, is the linear velocity of the fiber at the feeder outlet, is the feeder outlet cross-sectional area, To add time; After the raw materials enter the mixing tank in the set order and time, the stirring blades start working. The speed of the stirring blades is adjusted in real time according to the viscosity and density of the slurry. When the slurry viscosity is high, the speed of the stirring blades is increased to enhance the stirring effect, but the speed cannot exceed the maximum speed of the blades to avoid damage to the equipment. During the stirring process, the temperature and viscosity changes of the slurry are monitored in real time through the temperature sensor and viscosity sensor installed inside the stirring tank.

[0023] The temperature control adopts a circulating water cooling and heating system. When the slurry temperature is higher than the set upper limit, the cooling circulating water system is started to reduce the slurry temperature through heat exchange; when the temperature is lower than the set lower limit, the heating system is started to keep the slurry temperature within an appropriate range. Viscosity control is achieved by adjusting the amount of additives added or the speed of the stirring blades. When the viscosity is higher than the preset value, the amount of water reducer added is appropriately increased or the speed of the stirring blades is increased; when the viscosity is lower than the preset value, the amount of water reducer added is reduced or the speed of the stirring blades is reduced.

[0024] During the mixing process, the amount of water reducing agent added is reduced according to the above formula or the speed of the stirring blade is reduced according to the speed formula. During the mixing process, the performance of the slurry is monitored by a real-time slurry quality monitoring device. When the water seepage rate of the slurry is detected by a pressure water seepage instrument, the working principle of the pressure water seepage instrument is to put the slurry into a sealed container, let the water flow out through the filter under a certain pressure, and calculate the water seepage rate by measuring the volume and time of the water seepage. When the water seepage rate does not meet the requirements, the system automatically adjusts the mixing parameters or the amount of additives. When the strength test instrument is used to test the strength of the slurry test block, the test block is cured for a certain period of time under standard curing conditions, and then the test block is loaded by a pressure testing machine, and the strength value is calculated according to the failure load measured by the force sensor and the cross-sectional area of ​​the test block. If the strength is insufficient, the system optimizes the slurry performance by adjusting the cement dosage, the type of additives and the dosage method. For example, when increasing the cement dosage, the amount of cement to be added is calculated according to the strength difference and the relationship model between cement strength and slurry strength, and then accurately added through the spiral electronic scale 6.

[0025] The intelligent control module includes: Parameter monitoring unit, which monitors the grouting pressure, flow, slurry temperature, viscosity, humidity and equipment operation status parameters in real time during the grouting process; The automatic control unit automatically adjusts the parameters including the raw material ratio and mixing parameters of the slurry preparation module and the grouting pressure and flow rate of the grouting pumping module according to the monitoring data and the preset algorithm; The data analysis unit records the monitoring data in the database once per second to form a detailed grouting process record document, and uses data analysis software to perform statistical analysis on data including pressure, flow, and slurry quality, draw data change curves, and evaluate the grouting effect; The parameter monitoring unit monitors the humidity of the slurry through a humidity sensor. The humidity sensor monitors the humidity by measuring the change in capacitance value. and humidity The relationship follows the formula: in, , is the coefficient obtained through experimental calibration; Specifically, during the grouting process, various parameters are continuously monitored in real time and data is collected. In addition to pressure, flow, slurry temperature and viscosity parameters, the motor temperature and vibration amplitude parameters of the grouting pump 7 are also monitored using an equipment operation status monitoring device. The motor temperature sensor measures the motor surface temperature in real time. When the temperature exceeds the set safety threshold, the cooling fan is automatically started or the motor load is reduced to prevent the motor from overheating and damage. The vibration sensor monitors the vibration amplitude of the grouting pump 7. When the vibration amplitude increases abnormally, the system issues an alarm to prompt the operator to check whether the equipment is faulty or the pipeline is blocked. The slurry diffusion range monitoring device is used to monitor the diffusion of the slurry in the foundation in real time.

Transmit monitoring data to the intelligent control system in real time to provide a basis for subsequent data analysis and decision-making; The intelligent control system analyzes and processes the collected monitoring data in real time. By establishing a data analysis model, the changing trends of grouting pressure, flow rate, and slurry performance parameters are predicted and evaluated. When it is found that the parameters deviate from the preset range or show abnormal changes, the system automatically adjusts the grouting parameters or issues an alarm to prompt the operator to intervene manually; According to the monitoring results of the slurry diffusion range, the grouting position, pressure and flow parameters are adjusted in time to ensure that the slurry can fully fill the target formation area. At the same time, the data of each grouting process is stored and sorted to form a database to provide data support for subsequent engineering quality evaluation and system optimization.

During the grouting process, the intelligent control system monitors and controls the grouting pressure and flow rate in real time according to the preset grouting pressure and flow rate curve. When the grouting pressure is lower than the set value, the pressure is increased by increasing the motor frequency of the grouting pump 7 or reducing the valve opening; when the grouting pressure is higher than the set value, the pressure is reduced by reducing the motor frequency or increasing the valve opening. Flow control is achieved by adjusting the speed and valve opening of the grouting pump 7, according to the formula: in, is the grouting flow rate, is the pressure of grouting pump 7, is the slurry viscosity, , , , The coefficient is used to dynamically adjust the slurry injection flow rate. During the grouting process, pressure sensors and flow sensors are used to collect pressure and flow data in real time and transmit the data to the intelligent control system. The control system analyzes and processes the data. When abnormal pressure or flow fluctuations are found, the grouting parameters are adjusted in time or an alarm is issued to prompt the operator to check and handle the situation. The positioning module includes: Depth monitoring unit, which monitors the depth of the grouting pipe through a depth counter; The grouting pipe adjustment unit adjusts the angle and depth of the grouting pipe to control the grouting direction.

[0028] Specifically, the total station positioning system is used to accurately position the grouting equipment to ensure that the position of the grouting hole is accurate. During the grouting process, the angle and depth of the grouting pipe are adjusted according to the design requirements. The angle of the grouting pipe is adjusted through the electric hydraulic control device. The angle sensor feeds back the angle change information in real time. The control system accurately controls the angle adjustment accuracy based on the feedback information. The depth control of the grouting pipe is monitored by a depth counter, which calculates the depth value according to the speed and time of the grouting pipe being lowered or lifted. During the grouting process, the depth and angle of the grouting pipe are adjusted in real time according to the formation conditions and grouting effect to ensure that the slurry can be accurately injected into the target formation position.
