Abstract
Description
Technical Field
[0001] This invention belongs to the field of pile foundation technology, and in particular relates to an intelligent construction control method and system for jet grouting piles based on stratum information inversion. Background Technology
[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.
[0003] Jet grouting piles are widely used in foundation reinforcement and waterproofing curtains. They involve drilling a grouting pipe with a nozzle to a predetermined location in the soil layer using a drilling rig, or drilling a hole first and then placing the grouting pipe in the predetermined location. High pressure forces grout or water out of the nozzle, and the grout is injected while the rig rotates, mixing with the soil to form a cement-soil pile. The diameter and quality of jet grouting piles are closely related to soil conditions and construction conditions, including borehole diameter, injection method, nozzle diameter, injection pressure, grout mix ratio, and grouting pipe lifting speed. Mismatches between construction conditions and soil conditions (such as improper matching of injection pressure, pipe pulling speed, rotation speed, and grout volume) can easily lead to serious problems such as uneven strength of the consolidated body, necking, material waste, and low construction efficiency. Therefore, to comprehensively ensure pile quality and construction efficiency, dynamic control based on soil conditions is necessary. In engineering projects, a site with similar conditions is usually selected within the construction site for on-site testing to determine the construction process parameters. However, the geological conditions in the project are complex, and the actual geological distribution is not consistent with the geological distribution of the test site. Therefore, the construction process parameters are often not suitable for the actual soil layer of the project, resulting in low construction efficiency and poor quality of some jet grouting piles, and even pile breakage.
[0004] Currently, commonly used jet grouting equipment includes a high-pressure pump, a grout mixer, a drilling rig with drill rods, and a power head device that drives the drill rods to rotate. Existing technology determines soil layer distribution based on the real-time monitoring of the current value of the drilling rig's power head during construction. However, the current value is not only related to the soil layer type but is also affected by factors such as penetration pressure, velocity, and depth. Therefore, directly determining soil layer distribution and controlling construction process parameters based on the current value is inaccurate. Summary of the Invention

[0020] A computer device includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steps in the intelligent construction control method for jet grouting piles based on geological information inversion as described in the first aspect.

[0037] Example 1
[0038] This embodiment provides an intelligent construction control method for jet grouting piles based on geological information inversion, including the following steps:
[0039] S1, Install torque sensor 21 and pore water pressure sensor 22 on drill bit 15, install axial force sensor 23 on the lower part of drill rod 11, and complete the calibration of the sensors;
[0040] S2, move the high-pressure jet grouting drill 10 to the designated position, align the drill bit 15 with the center of the hole, and at the same time level the high-pressure jet grouting drill 10, placing it stably and horizontally;
[0041] S3, Drill a hole at a designated location, use a high-pressure jet grouting drill 10 to monitor the drilling depth and the output power of the drill in real time, and use a torque sensor 21, a pore water pressure sensor 22, and an axial force sensor 23 to sense the torque, pore water pressure, and axial force during the drilling process in real time.
[0042] S4, the wireless sensor network system receives the sensor wireless signal 17 and uploads the data to the data integration terminal 20;
[0043] S5 takes the received data as the input layer of the XGBoost machine learning model, and the output layer is the soil type, strength, water content and permeability coefficient.
[0044] S6 inputs the output soil layer type, strength, moisture content and permeability coefficient into the self-learning parameter matching module in the data integration terminal 20, and matches the best combination of construction parameters based on the optimal construction parameter database;
[0045] S7 inputs the optimal combination of construction parameters into the intelligent adjustment module of construction parameters in the data integration terminal 20, and automatically adjusts the construction parameters through the variable frequency speed and pressure regulating equipment (drilling drive motor and high-pressure variable frequency pump) to realize intelligent control of the construction process;
[0046] S8. Prepare cement slurry according to the optimal mud ratio output. First, add water to mixer 4, then pour in cement and admixtures, start the mixer and mix. After mixing, unscrew the valve on the right side of the mixer, pour into the screen 9 for filtration and flow into the slurry storage tank 8, and then pump it into the slurry storage tank 7 for later use through the mud pump.
[0047] S9. After drilling to the design depth, install the jet grouting pipe 5. After the jet grouting pipe 5 is inserted to the predetermined depth, the spraying operation is carried out from bottom to top. The construction is carried out according to the matching spraying pressure, lifting speed and rotation speed. The jet grouting pipe is lifted and rotated at the same time until the design length is reached and then the spraying is stopped.
[0048] S10. After the jet grouting operation is completed, due to the water separation effect of the grout, the solidified body generally shrinks to varying degrees, causing a depression at the top. It is necessary to replenish the grout in time. Open the valve on the left side of the grout storage tank 7 and spray static pressure grout into the hole through the grouting pipe 3 until the solidified body in the hole no longer sinks.
[0049] S11. Inject an appropriate amount of clean water into the slurry storage tank 7, turn on the high-pressure variable frequency pump 14, clean the residual cement slurry in all pipelines until it is basically clean, and clean the soil adhering to the rotary jet nozzle head.
[0050] S12, move the high-pressure jet grouting drilling rig 10 to the next construction position, and repeat the above steps to complete the construction of the jet grouting pile.
[0051] In S3 above, when the drill bit drills in different depths and different types of soil layers, the torque at the drill bit, the pore water pressure, the axial force of the drill rod, and the output power of the drilling machine are all different. Multi-source sensing devices are used to sense the above parameters in real time as a basis for judging the soil layer type.
[0052] In step S4 above, the sensor wireless signal is emitted from below the ground and is affected by the real-time drilling of the drill bit. To ensure the stability and accuracy of signal transmission, a hub is set up between the wireless signal and the receiving terminal to regenerate, shape and amplify the received signal, thereby expanding the signal transmission distance and maintaining signal stability.
[0053] In step S5 above, the XGBoost model balances speed and efficiency, enhancing gradient boosting performance. Employing a parallel tree boosting method accelerates model learning, allows it to run on different platforms and in various languages, and strengthens its non-linear learning capabilities and scalability, thus offering significant advantages in terms of efficiency and portability for prediction problems and practical applications. The XGBoost model algorithm flowchart is shown below. Figure 4 As shown, the specific construction process is as follows:
[0054] This invention uses a large database of engineering soil properties as training samples, and uses borehole depth, torque, axial force, pore water pressure and output power as the input layer of the model to establish the correspondence between the perceived information and the geological conditions. It uses soil type, strength, water content and permeability coefficient as the output layer to predict the geological conditions and retrieve the geological information in real time.
[0055] The XGBoost machine learning model continuously optimizes its parameters by learning from training samples, improving the efficiency and accuracy of identifying soil types at different depths. The identified soil types are basic soil types, such as sand, silt, and clay.
[0056] In step S6 above, the self-learning parameter matching system uses an artificial neural network to represent the construction parameter matching model as a mapping relationship with multiple inputs and multiple outputs:
[0057] f:Y=f(x)
[0058] In the formula, x is the input vector, x = (α1, α2, α3, ... α n ),α1-α n Representing the construction parameter components, Y is the output vector, Y = (β1, β2, β3, ..., β2). n ),β1-β n This represents the output performance component.
[0059] The construction parameter matching model is constructed by interconnecting a large number of processing units in some way; its basic unit is called a neuron. In a neural network, each neuron receives input signals from other neurons connected to it. Each input signal corresponds to a weight, and the weighted sum of all received signals determines the neuron's activation state. These neurons have local memory and can perform local operations. Each neuron has a single output connection, which can branch into several parallel connections as needed, outputting the same signal regardless of the number of parallel connections.
[0060] like Figure 5 As shown, the structure of a single neuron can be divided into input signal, input signal weights, external input signal, activation function, and output signal. Where x... l ,x2…x j …x n Indicates the input signal, w ij The weights of the input signal, s i Let f(·) be the external input signal, and y be the activation function. i This represents the output signal. The above model can be expressed as:
[0061]
[0062] The construction process of the self-learning parameter matching model includes: using an artificial neural network to implicitly express the mapping relationship, taking the data of construction parameters and pile quality as samples, inputting them into the constructed neural network for training, finding the nonlinear mapping relationship between the jet grouting pile construction parameters and the pile quality, storing this nonlinear mapping relationship on the connection weights of the input and output neurons, taking the jet grouting pile construction parameters as input and the pile quality as output, and obtaining the optimal combination of construction parameters through algorithm matching.
[0063] Furthermore, the mechanisms by which various construction parameters affect pile quality are complex and difficult to express with explicit mathematical expressions.
[0064] Therefore, the construction process of the self-learning parameter matching model includes:
[0065] The method uses an artificial neural network model to implicitly express the relationship between construction parameters and pile quality. This involves inputting the data of construction parameters and pile quality into the constructed neural network for training, finding the nonlinear mapping relationship between the jet grouting pile construction parameters and the pile quality, and storing this nonlinear mapping relationship in the connection weights of the input and output neurons. The jet grouting pile construction parameters are used as input quantities, and the pile quality is used as output quantities. The optimal combination of construction parameters is obtained through algorithm matching.
[0066] The optimal construction parameter database consists of jet grouting pile construction parameters under typical geological conditions obtained from a cloud platform, including mud ratio, mud volume, grouting pressure and grouting speed, as well as drilling speed, drill rod lifting speed and jet grouting pipe rotation speed.
[0067] This model features automatic learning, eliminating the need for a pre-established ideal model. It learns from the provided engineering construction data and adaptively establishes the mapping relationship between parameters, overcoming the difficulties of nonlinear mathematical modeling in traditional methods.
[0068] Furthermore, the optimal construction parameter database of the self-learning parameter matching system accumulates data on soil properties, construction parameters, and pile quality from existing jet grouting pile construction. The database supports updates and optimizations, ensuring the timeliness and applicability of the built-in data. Inputting the soil type, strength, moisture content, and permeability coefficient identified in the previous step, the self-learning parameter matching system automatically matches the construction parameters of jet grouting piles in the database, and outputs the optimal construction parameters based on an artificial neural network, with pile quality as the objective.
[0069] In step S7 above, the intelligent adjustment system for construction parameters is linked with the self-learning parameter matching system. When the soil type, strength, moisture content and permeability coefficient change, the self-learning parameter matching system updates the optimal construction parameters in real time. The intelligent adjustment system for construction parameters automatically adjusts the lifting speed and rotation speed and other construction parameters through the variable frequency speed-regulating pressure device according to the updated optimal parameter combination, so that the optimal construction parameters are used throughout the entire construction process of the jet grouting pile, thereby improving the quality and efficiency of pile formation.
[0070] The variable frequency speed and pressure regulating equipment includes a drilling drive motor and a high-pressure variable frequency pump. The drilling drive motor controls the drilling speed, the drilling rod lifting speed, and the rotation speed of the jet grouting pipe, while the high-pressure variable frequency pump controls the grouting pressure and the grouting speed.

By using the drilling rig and multi-source sensing components to sense drilling depth, torque, axial force, pore water pressure, and rig output power in real time, drilling depth, torque, axial force, pore water pressure, and output power are used as input parameters for formation inversion.
[0075] The wireless sensor network system includes a wireless transceiver chip, a low-power microcontroller 19, a hub 18, and a receiving terminal module, which are used to receive sensor data and transmit it to a data integration terminal 20.
[0076] Preferably, the microcontroller is an embedded ultra-low power microcontroller, which has the advantages of fast operation speed, strong stability and low power consumption.
[0077] Preferably, the hub is a stacked hub, which regenerates and expands the received signal to extend the network transmission interval and quickly transmit port data to the terminal system.
[0078] The data integration terminal is used to receive sensor signals, display sensor data, and input the data into the real-time formation information inversion module.
[0079] The real-time formation information inversion module is used to combine data on borehole depth, output power, torque, axial force, and pore water pressure during the drilling process with the XGBoost machine learning model to invert and obtain formation inversion data.
[0080] The construction parameter self-matching module is used to obtain the optimal combination of construction parameters based on the formation inversion data and the self-learning parameter matching model, and based on the optimal construction parameter database.
[0081] The intelligent adjustment module for construction parameters is connected to the self-matching system for construction parameters. It receives the optimal construction parameters transmitted by the self-matching system and controls the construction parameters in real time through variable frequency speed regulation equipment, thereby realizing intelligent control of the construction process and ensuring that the construction is carried out according to the optimal construction parameters.
[0082] Specifically, this includes linking the intelligent adjustment module for construction parameters with the self-learning parameter matching model. When the inversion data of the stratum changes, the self-learning parameter matching model updates in real time to obtain the updated optimal combination of construction parameters. The intelligent adjustment module for construction parameters automatically adjusts the construction parameters by controlling the variable frequency speed and pressure regulating equipment according to the updated optimal combination of construction parameters, so that the entire construction process of the jet grouting pile is carried out according to the optimal construction parameters.
