Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a grouting reinforcement and correction method for high-rise building structures. Background Technology

[0002] Architectural engineering technology is an important branch of civil engineering, focusing on the design, construction, maintenance, repair, and renovation of buildings. Its core objective is to ensure the safety, durability, and functionality of structures. This field involves the interdisciplinary integration of structural mechanics, materials science, geological engineering, and construction management. It primarily addresses the stability issues of high-rise buildings, historical buildings, or existing structures. Through assessment, reinforcement, correction, and monitoring (such as grouting, carbon fiber reinforcement, and jacking technology), it addresses damage caused by foundation settlement, material aging, load changes, or natural disasters to improve seismic performance, extend service life, and meet modern safety standards. Standardization is a key technological direction for ensuring the sustainable operation of urban infrastructure. One method for grouting reinforcement and correction of high-rise building structures involves injecting specific grouts (such as cement-based or chemical grouts) into the building foundation or structure to fill voids, strengthen the soil or concrete, and adjust the building's horizontal position using a controllable grouting process. Its purpose is to solve the tilting and structural instability problems of high-rise buildings caused by uneven foundation settlement, external loads, or environmental factors. By enhancing the overall bearing capacity, correcting the tilt, and reducing crack deformation, it ultimately restores the building to safe use conditions and prevents further damage.

[0003] Existing technologies rely on manual surveys and simple instruments for data collection, resulting in limited data coverage and susceptibility to subjective errors, affecting the comprehensiveness and accuracy of the assessment. Grouting schemes are mostly based on experience-based decisions, lacking systematic simulation and optimization processes, often leading to unreasonable grouting point layouts or inaccurate grout dosages, resulting in unstable corrective effects and significant resource waste. Insufficient real-time monitoring means it is difficult to monitor and adjust dynamic changes during construction in real time, resulting in slow corrective response and potentially delaying the optimal intervention time. Traditional grouting materials have limited performance and cannot adapt to environmental changes, leading to poor durability of reinforcement effects. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0073] Example:

[0074] like Figures 1-10 As shown, this embodiment of the invention provides a grouting reinforcement and correction method for high-rise building structures, including the following steps:

[0075] S1: Based on the current structural status of high-rise buildings, UAV laser scanning and sensor networks are used to collect building tilt data, foundation soil data and environmental data, and the data are initially integrated through data acquisition algorithms to generate an initial dataset;

[0076] S2: Based on the initial dataset, data cleaning and feature extraction algorithms are used to preprocess the data, remove noise and outliers, and data analysis and pattern recognition are performed through convolutional neural networks to construct a building tilt model and generate a preprocessed data model.

The layout of grouting points, grout type and injection sequence are optimized by genetic algorithm to minimize tilting error and generate an optimized grouting scheme.

[0078] S4: Based on the optimized grouting scheme, deploy an IoT sensor network to achieve real-time data transmission, and set the monitoring frequency and alarm threshold through network configuration algorithms to ensure that the system covers key areas and generate a real-time monitoring system;

[0079] S5: Based on data collected by the real-time monitoring system, the model predictive control algorithm is used to dynamically predict the building tilt trend, and the grouting parameters are adjusted through proportional-integral-derivative control to respond to real-time changes and generate dynamic adjustment parameters.

[0080] S6: Based on dynamically adjusted parameters, the grouting equipment is controlled to perform grouting operations. Intelligent responsive grout is used and precise injection is carried out through an adaptive injection system. Priority is given to implementation in settlement areas, and grouting execution records are generated.

[0081] S7: Based on grouting execution records and real-time monitoring system data, a closed-loop control algorithm is adopted to monitor grouting effect and tilt change in real time, and optimize the injection process through feedback loop, calibrate deviations in a timely manner, and generate real-time monitoring feedback.

[0082] S8: Based on real-time monitoring feedback, a multi-objective optimization algorithm is used to evaluate the correction effect, and a comprehensive evaluation report is generated through Pareto frontier analysis.

[0083] S9: Based on the effect evaluation report, use artificial intelligence algorithms to generate a final corrective summary and subsequent maintenance suggestions, and output visualized results through a report generation tool to ensure the continuous optimization of the solution and generate the final optimized solution.

[0084] Generating the initial dataset based on S1 involves the following steps:

[0085] S101: Based on the need for high-rise building correction, a drone equipped with a lidar and a high-definition camera module is used to perform three-dimensional laser scanning of the building facade and surrounding environment, and a high-precision building geometric model is obtained through a point cloud data generation algorithm to generate the initial point cloud model of the building.

[0086] To address the need for high-rise building alignment correction, a DJI Matrice 300 RTK drone equipped with a Zenmuse L1 LiDAR module was used. The drone was set to fly at an altitude of 50 meters and a speed of 5 meters per second to perform a 3D laser scan of the building facade. The scan path was pre-programmed as a spiral descent around the building. The LiDAR emitted pulsed lasers, measured distances, and recorded return times. Combined with GPS and IMU data, point cloud data was acquired. For example, for a building height of 100 meters and a scanned area of ​​2000 square meters, approximately 5 million point cloud data points were obtained. The point cloud density was calculated by dividing the total number of points by the scanned area: 5,000,000 / 2000 = 2500 points / m². CloudCompare software was used for point cloud processing, applying a statistical outlier removal algorithm to calculate the average distance from each point in the point cloud to its neighbors, obtaining the mean μ and standard deviation σ. A threshold of μ ± σ was set. 2σ, for example, if μ is 10 meters and σ is 0.5 meters, then points whose distance values ​​are not in the range of 9.0 to 11.0 meters are removed. After processing, the point cloud is registered and triangulated to generate a high-precision three-dimensional mesh model with vertex position accuracy error of less than 1 cm, and the initial point cloud model of the building is generated.

[0087] S102: Based on the initial point cloud model of the building, a key point sensor network is deployed inside the building and on the foundation. The real-time deformation and tilt data of the structure are automatically collected through the wireless sensor network protocol to generate a real-time structural monitoring dataset.

[0088] Based on the initial point cloud model of the building, wireless tilt sensors and strain gauges are deployed at key locations such as corners and the foundation. The sensor type is SICK DT1000 tiltmeter, with a sampling frequency of 10Hz. They are networked via the ZigBee wireless protocol to automatically collect real-time deformation data. The tilt data is recorded as angle values, for example, the sensor reading shows a tilt angle of 0.5 degrees. The data is transmitted to the central server through the gateway. The data packet includes a timestamp, sensor ID, and measurement value. Data integrity is checked using data verification algorithms, such as CRC check, to ensure no data loss or errors. The acquisition cycle is once per minute for 24 hours, generating a real-time structural monitoring dataset containing time-series data.

[0089] S103: Based on the real-time structural monitoring dataset, the foundation exploration is carried out using ground-penetrating radar and standard penetration test methods to obtain soil layer distribution, density and groundwater level data, and then the data are digitized through geological statistical analysis to generate a foundation geological attribute database.

[0090] Based on the real-time structural monitoring dataset, ground exploration was conducted using ground-penetrating radar equipment such as the GSSI SIR-4000. The radar antenna frequency was 100MHz, and the scanning depth was 20 meters to acquire soil reflection signals. After filtering and gain adjustment, soil interfaces were identified. For example, a clay layer with high reflection intensity was found at a depth of 5 meters. At the same time, standard penetration tests were conducted using a 63.5kg hammer to record the number of blows (N) per 30cm of penetration. For example, at point A, the N value was 15, indicating medium density. Groundwater level was measured through boreholes and water level gauges at a depth of 3 meters. The data was digitized and stored in tables. The soil layer distribution was represented by a layered model, and the thickness and properties of each layer were recorded to generate a ground geological property database.

[0091] S104: Based on the initial point cloud model of the building, the real-time monitoring dataset of the structure, and the geological attribute database of the ground, a data fusion algorithm is used to perform spatiotemporal registration and integration of multi-source heterogeneous data, eliminate noise and conflicts, form a basic data package in a unified format, and generate the initial dataset.

[0092] Based on the initial point cloud model of the building, the real-time structural monitoring dataset, and the geological attribute database, a data fusion algorithm such as Kalman filtering is used to perform spatiotemporal registration of the multi-source data. First, the point cloud model is aligned with the monitoring data in time using timestamp matching. Then, spatial registration is performed through coordinate transformation, such as moving the sensor coordinate system to the point cloud coordinate system. Data conflict resolution uses a weighted average, with weights based on data accuracy: point cloud data weight 0.6, sensor data weight 0.3, and geological data weight 0.1. Noise removal is performed using a low-pass filter with a cutoff frequency of 0.1Hz. A unified format CSV file containing all integrated data is generated, thus creating the initial dataset.

[0093] The steps involved in generating the preprocessed data model based on S2 are as follows:

[0094] S201: Based on the initial dataset, a statistical outlier detection algorithm is used to identify and remove obvious errors and noisy data points generated during the collection process, generating a cleaned dataset;

[0095] Based on the initial dataset, a statistical outlier detection algorithm is used to calculate the outlier detection value for each data point. , Where X is the data value, μ is the mean, and σ is the standard deviation. A threshold is set: |Z-score| > 3 is considered an anomaly. For example, if the tilt data has μ of 0.4 degrees and σ of 0.1 degrees, it will be removed. Points with a value greater than 3 or less than -3, such as points with a value of 0.8 degrees. The data was removed, and after cleaning, a moving average smoothing was applied with a window size of 5 points to generate the cleaned dataset.

[0096] S202: Based on the cleaned dataset, the principal component analysis algorithm is used to reduce the dimensionality of the high-dimensional monitoring data, extract the main feature components that best represent the building tilt and settlement trend, and generate the building settlement main feature vector.

[0097] Based on the cleaned dataset, principal component analysis algorithm is used to calculate the covariance matrix of the data and extract principal components through eigenvalue decomposition. For example, if the dataset has 10 variables, the variance contribution rate of the first principal component is 80% after calculation. The first 3 principal components are retained, and the eigenvectors represent the tilt trend. After dimensionality reduction, the data is projected onto the principal component space to generate the main eigenvectors of building settlement.

[0098] S203: Based on the main feature vector of building settlement, a convolutional neural network algorithm is used to perform deep learning on historical and real-time tilt patterns to identify settlement patterns, rates and potential risk areas, and generate a building tilt pattern identification report.

[0099] Based on the main feature vector of building settlement, a convolutional neural network algorithm is adopted. The network structure includes convolutional layers, pooling layers, and fully connected layers. The input is time series data with a sequence length of 100 time points, a convolutional kernel size of 3, and a stride of 1. Historical data is used to predict tilt patterns. For example, if the input is data from the past week, the output will show the future trend. The settlement rate is identified, such as 0.1 mm per day. Risk areas are identified by outputting a probability map. A probability > 0.7 indicates high risk. A building tilt pattern recognition report is generated.

[0100] S204: The preprocessed data model is generated by combining the cleaned dataset, the main feature vector of building settlement, and the building tilt pattern recognition report, and using data standardization methods to normalize all features to the same dimension and encapsulate them into standard data objects that can be called by the model.

[0101] Based on the comprehensive cleaned dataset, the main feature vector of building settlement, and the building tilt pattern recognition report, a data standardization method was used to scale each feature to the range [0,1]. The formula is as follows: ,in and To determine the minimum and maximum values ​​of features, for example, if the tilt angle X_min = 0 degrees and X_max = 1 degree, then the value 0.5 degrees is standardized to 0.5. All features are encapsulated into JSON objects to generate a preprocessed data model.

[0102] The optimized grouting scheme for S3 includes the following steps:

[0103] S301: Based on the preprocessed data model, a high-precision three-dimensional digital twin model containing the building structure, foundation soil layer and sensor points is constructed using building information modeling software to generate a building-foundation digital twin model.

[0104] Based on the preprocessed data model, point cloud data and geological data are imported using building information modeling software such as Autodesk Revit to construct a three-dimensional digital model. The model includes building structural layers, foundation soil layers, and sensor points. The soil layer thickness is set according to the geological data, for example, the clay layer thickness is 2 meters.
