Description

Technical Field

[0001] The present invention relates to the technical field of geotechnical engineering pile foundation equipment, and in particular to an intelligent construction method based on intelligent cast-in-place large-diameter pipe pile equipment. Background Art

[0002] PCC piles have shown many outstanding advantages in the process of reinforcing soft soil foundations. Due to the use of double-layer casing wall, the stability of the soil on both sides can be well maintained. Therefore, PCC piles are suitable for various complex geological conditions and have a large pile depth. The double-layer steel pipe cavity structure can form a pipe pile with a larger pile diameter, and the pile diameter and the wall thickness of the pipe pile can be adjusted as needed. Compared with solid piles with the same effective cross-sectional area, the PCC pile has a larger contact area with the soil around the pile, which can greatly increase the friction resistance of the pile side, save the amount of concrete used in the pile body, and reduce the project cost. The PCC pile driver adopts a flap pile shoe structure, which overcomes some of the shortcomings of using prefabricated reinforced concrete pile heads. In addition to reducing costs, it speeds up the construction progress. The inclination direction of the pile shoe can be set to adjust the direction of soil extrusion during the sinking process. Through the slurry maker, the friction resistance inside and outside the annular sleeve mold can be reduced during sinking, protecting the stability of the pile core soil and side wall soil. Due to the use of the vibrating double-layer casing molding process, the construction quality is stable and easy to control. Because cast-in-place concrete large-diameter pipe piles have the advantages of strong construction adaptability, wide application range, easy control of construction quality, low reinforcement cost per unit area, and outstanding reinforcement effect, they have great promotion and application value and have been widely used in engineering.

[0003] However, there are still some shortcomings in the existing PCC piles. First, there are various complex soil layers in engineering construction, especially when cast-in-place concrete pipe piles are promoted and applied from the soft soil areas in the east to the central and western regions, they often encounter hard and thick soil layers. The traditional sinking pipe cast-in-place pile method is difficult to penetrate the hard soil layer, and this method is not very applicable. Secondly, with the development of the economy and society, PCC pile construction faces a more complex construction environment, and the current PCC pile foundation construction has too much human participation and a low degree of intelligence. Therefore, it is necessary to achieve comprehensive intelligence in construction so that the application scope of PCC piles, construction efficiency and pile quality can be significantly improved. Based on this, it is urgent to combine artificial intelligence technology with pile foundation engineering technology, develop a new generation of new intelligent cast-in-place concrete large-diameter pipe piles (abbreviated as i PCC piles) technology and equipment, and gradually improve and improve them to form a system that can be applied in representative engineering demonstrations.

[0004] Therefore, it is necessary to develop a new type of intelligent cast-in-place large-diameter pipe pile equipment to realize fully automatic rotary excavation to form circular holes, fully automatic pouring of concrete to form piles, and real-time intelligent analysis and feedback of data from the entire construction process.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work belong to the scope of protection of the present invention.

[0036] Example

[0037] See also Figures 1 to 4 , an intelligent construction method based on intelligent cast-in-place large-diameter pipe pile equipment, which is constructed through intelligent cast-in-place large-diameter pipe pile equipment.

[0038] In this embodiment, the above-mentioned intelligent cast-in-place large-diameter pipe pile equipment includes a power equipment module 1, a double-layer casing arm module 2, a ring-shaped rotary drilling module 3, a self-propelled frame module 4 and a concrete pouring module.

[0039] Specifically, the self-propelled frame module 4 adopts a crawler walking structure, and the crawler is composed of high-strength alloy steel chains and wear-resistant rubber blocks, which can effectively disperse the weight of the equipment and reduce the pressure on the ground, thereby adapting to construction sites with various geological conditions, such as soft mud, solid rock ground and terrain with a certain slope.

[0040] In order to realize accurate automatic walking of the equipment in the construction site, in this embodiment, the self-propelled frame module 4 is equipped with an automatic navigation and positioning system (navigation and positioning method of the device). The system integrates the global satellite navigation system (GNSS), inertial measurement unit (IMU) and ultra-wideband positioning system (UWB).

[0041] Among them, GNSS provides high-precision absolute position information, IMU measures the attitude angle and acceleration changes of the equipment in real time, and UWB positioning technology is used for high-precision relative positioning in a close range (such as when obstacles block the GNSS signal in the construction area). Through the data fusion algorithm, the information obtained by these three technologies is comprehensively processed, so that the equipment can move accurately along the preset construction route, and the positioning accuracy can reach the centimeter level. At the same time, a laser obstacle avoidance sensor is installed on the rack to scan the surrounding environment in real time. When an obstacle is detected, the walking route is automatically adjusted to avoid collision.

[0042] The above-mentioned double-layer casing arm protection module 2 includes an outer cylinder 21, an outer cylinder fixing clamp 22, an inner cylinder 23, an inner cylinder fixing clamp 24, an outer cylinder lifter 25 and an inner cylinder separation hydraulic cylinder 26; in this embodiment, the double-layer casing in the double-layer casing wall protection system can be assembled and locked with multiple sections of casing at different heights according to the on-site construction conditions and using a casing adapter 27, so as to flexibly meet the pile height requirements under different on-site conditions.

[0043] In this embodiment, the double-layer casing arm guard module 2 is collaboratively controlled by multiple hydraulic cylinders. Each hydraulic cylinder is equipped with a high-precision displacement sensor and a pressure sensor for real-time monitoring of the stroke and stress of the cylinder. During the casing lowering process, according to the pre-set construction parameters, the control system automatically adjusts the pressure and speed of the hydraulic cylinder according to the geological exploration data and the real-time monitored casing stress conditions to ensure that the casing sinks smoothly. After the concrete pouring is completed, the lifting process of the casing is also strictly controlled. By real-time monitoring of the friction between the casing and the concrete and the lifting speed of the casing, it is possible to avoid uneven concrete surface or pile body quality problems caused by too fast lifting speed.

[0044] The above-mentioned annular rotary drilling module 3 includes an auger 31, an auger lifting mechanism 32 and an auger fixing clamp 33; in this embodiment, the annular rotary drilling system can realize fully automatic rotary drilling to take soil into annular holes, fully automatic pouring of concrete to form piles, and real-time intelligent analysis and feedback of data from the entire construction process.

[0045] During construction, the double-layer casing wall protection module 2 and the annular rotary drilling module 3 are pressed down synchronously to drill to the specified depth. The inner tube 23 is pressed down and forcibly squeezed and implanted into the soil by the inner tube separation hydraulic cylinder 26 to prevent the inner tube 23 from being pulled out or the bottom shaking when the auger 31 is lifted. Finally, the auger 31 is lifted, and concrete is poured, and the pipe is pulled out by vibration to form a pile. The whole process realizes fully automatic control of the auger pulling speed, and intelligent analysis and feedback of the pile effect data.

[0046] In this embodiment, the intelligent construction method based on intelligent cast-in-place large-diameter pipe pile equipment includes the following steps:

[0047] S1. Preparation before construction, treatment of the work site and determination of pile positions;

[0048] In this embodiment, in the early stage of the operation, all irrelevant debris and underground facilities that may affect the construction are removed. During construction, the ground of the construction site is kept as flat as possible, the soft surface needs to be treated, and the drainage work of the site should be done well.

[0049] Through the intelligent pipe pile design software, the engineering geological profile and stratum parameters are obtained from the site survey, and the corresponding data is transmitted to the platform, which integrates finite element analysis, Lizheng and other geotechnical software. The platform then outputs the design parameters (such as pile length, pile diameter, pile spacing, and pile layout plan, etc.). The axis control piles and leveling point piles must be set and numbered, and the PCC pile hole positions must be marked and marked. The drilling and bearing capacity tests must be done in advance to determine the construction parameters and ensure that the bearing capacity can meet the requirements. The construction personnel must calibrate the control points according to the plan and PCC pile position map, draw the PCC pile position layout map according to the detailed number of PCC piles in the engineering design, and mark the determined PCC pile positions.

[0050] S2. Equipment installation and commissioning: Install intelligent cast-in-place large-diameter pipe pile equipment, connect each module with the intelligent pipe pile design platform, and perform automatic navigation and positioning through the IPCC pile intelligent control system;

[0051] S3, during the drilling process, the i PCC pile intelligent control system controls the double-layer casing wall protection module and the annular rotary drilling module to synchronously press down and drill to the specified depth;

[0052] In this embodiment, the method for controlling the double-layer casing wall protection module by the i PCC pile intelligent control system includes the following steps:

[0053] S31 a. During the casing lowering process, according to the pre-set construction parameters, the control system automatically adjusts the pressure and speed of the hydraulic cylinder according to the geological exploration data and the casing stress conditions monitored in real time to ensure the casing sinks smoothly; when the casing is lifted, the friction between the casing and the concrete and the lifting speed of the casing are monitored in real time to avoid uneven concrete surface or pile quality problems caused by too fast lifting speed;

[0054] S32a. During construction, the double-layer casing wall protection system and the annular rotary drilling system are pressed down synchronously to drill to the specified depth; the inner tube is pressed down and forcibly squeezed into the soil by the inner tube separation hydraulic cylinder to prevent the inner tube from being pulled out or the bottom from shaking when the auger is lifted.

[0055] S4, during the concrete pouring process, the circular rotary drilling module is lifted, and the concrete pouring module is controlled by the i PCC pile intelligent control system to pour concrete, and the pipe is pulled out by vibration to form piles;

[0056] In this embodiment, the method for pouring concrete by controlling the concrete pouring module through the iPCC pile intelligent control system includes the following steps:

[0057] S31 b, the concrete delivery pipe connected to the ground pump is spirally connected to the liquid inlet pipe through the winding disc frame to form a concrete pouring system;

[0058] S32b, the mixed concrete is pressed into the concrete delivery pipe through a ground pump, and is delivered to the inner and outer sleeve cavity structure through a liquid inlet pipe connected to the movable slide rail and a feed hopper.

[0059] S5. Real-time monitoring of pile quality is carried out through the intelligent pipe pile design platform.

[0060] In this embodiment, the real-time monitoring of pile quality is performed through the intelligent pile design platform as follows:

[0061] The pile quality is tested by static load test, core drilling method, low strain method, high strain method and acoustic wave transmission method, and the pile quality assessment model is established by using data analysis and processing technology.

[0062] Furthermore, the model comprehensively considers the data collected by various sensors, such as strain data, stress wave propagation data, ultrasonic detection data, etc., as well as the design parameters and construction process data of the pipe piles. A large amount of detection data and the corresponding pile quality assessment results are trained through machine learning algorithms (such as decision trees, support vector machines, etc.) to establish a quality assessment model. According to the results of the model output, the pile quality is quantitatively evaluated to determine whether the pile body meets the design requirements, whether there are quality problems and the severity of the problems. At the same time, according to the quality assessment results, a basis is provided for subsequent construction improvements and quality control measures.

[0063] In this embodiment, the above-mentioned iPCC pile intelligent control system includes an intelligent pipe pile design subsystem, a fully automatic construction subsystem, and an integrated sensing monitoring and remote control subsystem.

[0064] The developed iPCC pile intelligent control software mainly includes: intelligent pipe pile design software, fully automatic construction system, integrated sensing, monitoring and remote control platform system. The intelligent pipe pile design software obtains engineering geological profiles and stratum parameters through site survey, including the depth, thickness, soil type (such as clay, sand, silt, etc.) of different soil layers, and the physical and mechanical parameters of each soil layer (such as density, internal friction angle, cohesion, compression modulus, etc.), and transmits the corresponding data to the platform, which integrates finite element analysis, rationalization, BIM and other software, and then outputs design parameters (such as pile length, pile diameter, pile spacing and pile layout plan, etc.).

[0065] In this embodiment, the intelligent pipe pile design software uses software automation design algorithms to automatically generate a variety of design drawings and construction plans for selection based on input parameters (such as geological conditions, load requirements, etc.), combined with finite element analysis software simulation results and integrated machine learning algorithms to analyze historical design data and construction feedback, thereby providing optimization suggestions and improved design plans, and realizing visual design through BIM multi-professional collaboration.

[0066] Among them, in supervised learning algorithms, support vector machine (SVM) algorithm can be used for classification and regression analysis, can handle nonlinear problems, and is suitable for complex pile foundation design optimization; gradient boosting machine (GBM): integrates multiple weak prediction models to improve prediction performance; random forest: integrates multiple decision trees to improve prediction accuracy and robustness. In unsupervised learning algorithms, clustering algorithms: such as K-means, are used to identify natural groupings in data, and may be used to analyze construction data and discover different construction modes or anomalies. Principal component analysis (PCA): used for dimensionality reduction, reducing the number of variables in the data set while retaining the most important information, and can be used to simplify design parameters. In reinforcement learning algorithms, Ql earning: learns the optimal strategy through interaction with the environment, and may be used to dynamically adjust parameters during the construction process to achieve the best construction effect. In deep learning algorithms, convolutional neural network (CNN): suitable for image data, design software involves image analysis (such as image analysis of geological profiles), CNN can extract features and make predictions; recurrent neural network (RNN): suitable for sequence data, analyze time series data (such as time series data during construction), RNN can capture time dependencies.

[0067] i PCC pile automatic construction system eliminates the tedious steps of traditional PCC pile construction. It only needs to import pile points, correct coordinates, select pile points, and construct piles to complete the construction of PCC pile foundation. It adopts Beidou real-time dynamic positioning technology, combined with the installed Beidou / GNSS antenna, and collects various sensor indicators through pile foundation sensors (current sensors, tilt sensors, injection volume sensors, etc.) and data acquisition systems to read the real-time and accurate three-dimensional position information of the PCC pile head, the inclination angle of the pile body, as well as the drilling and lifting speed, depth, drilling rig current, etc., and then transmits it to the mobile phone APP, PC computer terminal, and monitoring center of the third-party device through the Internet and cloud server to adjust the pile foundation construction parameters in real time, and the pile foundation equipment control interface displays the pile foundation construction status in real time. The remote monitoring platform integrates video monitoring, equipment operation status perception, remote operation and other functions. The quality, progress data, working status, etc. of pile foundation construction can all be managed through the cloud platform.

[0068] This embodiment provides an intelligent construction method based on intelligent cast-in-place large-diameter pipe pile equipment, which realizes rapid intelligent design according to real-time geological conditions, realizes fully automatic control of the construction process, identifies parameters such as pile penetration depth and speed in real time, inverts the rationality of soil layer parameters, and conducts research on automatic perception and detection of pile quality.

[0069] According to the relationship between data characteristics and soil parameters, select appropriate inversion models, such as artificial neural networks (ANN), Bayesian networks, etc. Use a large amount of field test data and cases with known soil parameters to train and verify the model. During the training process, cross-validation, regularization and other methods are used to prevent model overfitting and improve the generalization ability of the model. As the construction progresses, new data is continuously accumulated, and the inversion model is updated and optimized using the new data. According to the error between the new data and the model prediction results, the parameters and structure of the model are adjusted. At the same time, new geological information and construction condition change information are introduced to enable the inversion model to adapt to different construction scenarios and improve the accuracy of soil parameter inversion.

[0070] In this embodiment, a highly stable sensor is installed on the pile foundation to monitor the deformation, stress, etc. of the pile foundation in real time, accurately grasp the various parameters in the construction process, and establish a virtual model of the pile foundation construction through the digital twin of the whole process. The digital recording and monitoring of the construction process is realized by the correspondence between the physical entity and the virtual entity, and the response of the equipment and the foundation soil during the pile foundation construction is measured to analyze the influence of the pile sinking effect.

[0071] Through data analysis, a model is established to predict the load and deformation of pile foundation construction. Through data analysis, the problems existing in pile foundation construction are understood, and timely measures are taken to repair and adjust them to ensure construction quality. Based on real-time construction data and preset construction standards, expert systems and fuzzy logic control algorithms are used to make intelligent decisions. When construction parameters (such as penetration depth, speed, pressure, etc.) deviate from the preset range, the control system automatically adjusts the operating parameters of the construction equipment. For example, if the penetration speed is too fast, the control system reduces the power output of the pile driver; if the penetration depth is insufficient, the verticality of the pile driver is adjusted or the penetration pressure is increased. At the same time, according to the construction progress and geological changes, the construction sequence and construction process are dynamically optimized to ensure construction quality and efficiency. Intelligent data analysis and technology can more accurately predict and evaluate the pile sinking effect, adjust the construction plan in time, reduce construction risks, and improve construction efficiency and quality.

[0072] Research the optimal equipment parameters and process parameters, collect construction parameter data, and use data analysis technologies such as data sharing, cloud servers, artificial intelligence algorithms, etc. to achieve remote monitoring of the construction site and instant evaluation of construction quality, and establish process templates. When conducting process design for similar products, establish process templates, integrate process routes, procedures, steps and related requirements to form a process information framework. Through intelligent process parameter decision-making and control systems, the construction process can be controlled more accurately and the degree of automation of construction can be improved.

[0073] The fully automatic construction system provided in this embodiment eliminates the cumbersome steps of traditional PCC pile construction. It only needs to import pile points, correct coordinates, select pile points, and construct piles to complete the construction of PCC pile foundation. Beidou real-time dynamic positioning technology is used, combined with the installed Beidou / GNSS antenna, and various sensor indicators are collected through pile foundation sensors (current sensors, tilt sensors, injection volume sensors, etc.) and data acquisition systems to read the real-time and accurate three-dimensional position information of the PCC pile head, the inclination angle of the pile body, as well as the drilling and lifting speed, depth, drilling rig current, etc., and then transmitted to the mobile phone APP, PC computer terminal, and monitoring center of the third-party device through the Internet and cloud server to adjust the pile foundation construction parameters in real time, and the pile foundation equipment control interface displays the pile foundation construction status in real time. The remote monitoring platform integrates video monitoring, equipment operation status perception, remote operation and other functions. The quality, progress data, working status, etc. of pile foundation construction can all be managed through the cloud platform.
