Description

Technical Field

[0001] The invention relates to the technical field of engineering construction, and in particular to a pile hole rapid positioning method. Background Art

[0002] Rotary drilling is a common construction method in foundation engineering, particularly for pile foundations. Traditional methods for locating pile holes often rely on manual measurement and calibration, which is prone to errors and significantly affected by factors such as the construction environment and weather. Therefore, an efficient, accurate, and convenient pile hole locating method is urgently needed to improve the accuracy and efficiency of rotary drilling. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the technical problem to be solved by the present invention is: how to improve the accuracy and efficiency of rotary drilling construction.

[0004] The technical solution adopted by the present invention to solve its technical problem is: A pile hole rapid positioning method comprises the following steps: S1: Data acquisition and modeling: Collect all design data related to construction, use BIM modeling software to convert the pile foundation design data into a 3D model; integrate geographic information and environmental information from the GIS system into the 3D model; establish a BIM platform to synchronize and update design and construction site data in real time; S2: Construction site monitoring: by installing sensors and connecting to the GIS system, the geographic information and environmental information of the construction site can be input and monitored in real time; S3: VR virtual reality simulation, based on BIM and GIS models, uses VR technology to virtualize the entire construction site and create an interactive three-dimensional virtual environment; S4: Pile hole positioning: During construction simulation in a 3D virtual environment, the system automatically detects whether there is any deviation in the pile hole and issues a timely warning message. At the same time, the pile hole is positioned on the ground, and the real-time positioning information is compared with the simulated pile hole positioning information in the 3D virtual environment. If there is a deviation in the actual pile hole position, the construction personnel can enter the virtual environment through VR technology to adjust the position. S5: Data storage and management, all design, construction, positioning and virtual adjustment data will be stored through the cloud platform.

[0005] Furthermore, the design data includes design drawings of the pile foundation, soil testing reports, pile hole dimensions, and soil layer conditions.

[0006] Furthermore, the three-dimensional model includes detailed data on pile hole location, depth, size, structural requirements of the pile foundation, surrounding environment information, and infrastructure.

[0007] Furthermore, in step S2, GIS technology is used to monitor and analyze the topography, groundwater level, traffic conditions, and building distribution of the construction site; spatial analysis tools are used to evaluate the impact of different geographical areas on pile foundation construction and optimize the layout of pile holes; and possible environmental risks in the construction area are predicted.

[0008] Furthermore, in step S3, each pile hole is positioned in the three-dimensional virtual environment, and its parameters such as position, depth, and direction are adjusted, and the pile hole is fine-tuned using virtual tools.

[0009] Furthermore, when conducting construction simulation in virtual reality, the system will automatically detect whether there is any deviation in the pile hole and issue early warning information in a timely manner. Construction personnel can use virtual reality to predict the pile hole position and potential problems in the construction process and make necessary adjustments and optimizations.

[0010] Furthermore, the field positioning uses GPS, laser scanner or drone equipment to perform real-time positioning of the pile hole.

[0011] Furthermore, the entire construction site was scanned by a laser scanner, and the scanned data was compared and analyzed with the pile hole data in the 3D virtual environment.

[0012] Furthermore, the on-site positioning data is compared with the data in the three-dimensional virtual environment. If any position deviation is found, the system will automatically record it and provide adjustment suggestions.

[0013] The beneficial effects of the present invention are: By integrating BIM with GIS, all design data is displayed in a 3D virtual environment, allowing construction workers to more intuitively check the precise location of pile holes. The GIS system also monitors pile hole positions in real time and further precisely locates them using GPS or differential GPS technology, reducing manual errors. Using VR technology, construction workers can quickly fine-tune pile hole positions in a virtual environment, making precise adjustments. This not only reduces deviations but also allows each adjustment to be verified through virtual reality simulation, ensuring accurate pile hole positioning. Construction workers no longer need to conduct complex on-site measurements and repeated adjustments. Real-time simulation and optimization in a virtual environment can identify potential problems in advance and enable thorough verification before actual construction, saving significant time. Rapid adjustment and precise control of pile hole positions can significantly shorten construction cycles and reduce ineffective work. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1 As shown, the embodiment of the present application proposes a pile hole rapid positioning method, comprising the following steps: S1: Data acquisition and modeling: Collect all design data related to construction, use BIM modeling software to convert the pile foundation design data into a 3D model; integrate geographic information and environmental information from the GIS system into the 3D model; establish a BIM platform to synchronize and update design and construction site data in real time; S2: Construction site monitoring: by installing sensors and connecting to the GIS system, the geographic information and environmental information of the construction site can be input and monitored in real time; S3: VR virtual reality simulation, based on BIM and GIS models, uses VR technology to virtualize the entire construction site and create an interactive three-dimensional virtual environment; S4: Pile hole positioning: During construction simulation in a 3D virtual environment, the system automatically detects whether there is any deviation in the pile hole and issues a timely warning message. At the same time, the pile hole is positioned on the ground, and the real-time positioning information is compared with the simulated pile hole positioning information in the 3D virtual environment. If there is a deviation in the actual pile hole position, the construction personnel can enter the virtual environment through VR technology to adjust the position. S5: Data storage and management, all design, construction, positioning and virtual adjustment data will be stored through the cloud platform.

[0017] First, it's important to note that by integrating BIM with GIS, all design data is displayed in a 3D virtual environment, allowing construction workers to more intuitively check the precise location of pile holes. The GIS system also monitors pile hole positions in real time and further pinpoints them using GPS or differential GPS technology, reducing manual errors. Using VR technology, construction workers can quickly fine-tune pile hole positions in a virtual environment, making precise adjustments. This not only reduces deviations, but also allows each adjustment to be verified through virtual reality simulation, ensuring precise pile hole positioning. Construction workers no longer need to conduct complex on-site measurements and repeated adjustments. Real-time simulation and optimization in a virtual environment can identify potential problems in advance, allowing for thorough verification before actual construction, saving significant time. Rapid adjustment and precise control of pile hole positions can significantly shorten construction cycles and reduce ineffective work.

[0018] Specifically, in step S1, the design data includes pile foundation design drawings, soil test reports, pile hole dimensions, and soil conditions. All construction-related design data, including the pile foundation design drawings, soil test reports, pile hole dimensions (diameter, depth), and soil conditions, is collected. Using BIM modeling software (such as Revit or Tekla), the pile foundation design data is converted into a 3D model. This model includes information such as the pile hole location, depth, dimensions, structural requirements, and surrounding environment. Detailed infrastructure data, such as surrounding buildings, roads, and underground pipelines, is incorporated into the BIM model to ensure compatibility between the pile hole design and the actual environment. Geographic information (such as topography, groundwater level, and soil type) from the GIS system is integrated with the BIM 3D model for comprehensive analysis. Environmental data provided by the GIS, such as soil type distribution and groundwater level, is incorporated into the BIM model to accurately simulate the actual conditions of pile foundation construction in a virtual environment. Appropriate engineering constraints and conditions, such as the distance from surrounding buildings and the stability of the surrounding soil, are incorporated into the model to ensure the rationality of the design. A BIM platform is established to synchronize and update design and construction site data in real time. When there are any changes on site, the model will immediately reflect these adjustments to ensure that design and construction proceed in sync. Engineers can view detailed information about the current construction stage through the BIM model, identify problems and make adjustments in a timely manner.

[0019] In step S2, GPS positioning technology is used to obtain the construction site's geographic location and coordinate data in real time. During construction, positioning sensors or drones are installed to track the construction positions of the pile holes in real time, ensuring that the actual location of each pile hole is consistent with the designed position. The GIS system integrates data from various sensors (such as soil moisture, temperature, and pressure) to provide real-time feedback to construction personnel, ensuring that every aspect of the construction process is under control.

[0020] GIS technology is also used to conduct a detailed analysis of the construction site's surrounding environment, including topography, groundwater levels, traffic conditions, and building distribution. Spatial analysis tools are used to assess the impact of different geographic regions on pile foundation construction and optimize pile hole layout. Potential environmental risks within the construction area (such as soil erosion and geological disasters) are predicted to provide a basis for decision-making in pile foundation construction. The GIS platform integrates the construction site's geographic information with the BIM model, presenting the location and construction progress of pile holes in real time via 2D or 3D maps. Engineers and managers can use the GIS platform to fully monitor construction site progress, using maps to view the actual location of each pile hole and ensure accurate execution of the construction plan.

[0021] In step S3, the entire construction site is virtualized using VR technology based on the BIM and GIS models, creating an interactive 3D virtual environment. Engineers and construction workers, wearing VR headsets, can immerse themselves in the virtual construction site and precisely position, adjust, and optimize pile holes. Within this virtual environment, using a handle or touchscreen, users can adjust the designed pile hole position in real time and view the impact of these adjustments on the overall construction plan.

[0022] In the virtual environment, each pile hole can be positioned, and its position, depth, orientation, and other parameters can be adjusted. Fine-tuning can be performed using virtual tools. Engineers can simulate the construction process under different environmental conditions (such as varying soil types and groundwater level fluctuations) and evaluate the effectiveness of the adjusted pile holes in real time. During construction simulations in virtual reality, the system automatically detects any deviations in the pile holes and issues timely warnings. Construction personnel can use virtual reality to predict pile hole locations and potential problems during construction, making necessary adjustments and optimizations to minimize the occurrence of problems during actual construction.

[0023] VR technology can be used for construction worker training, helping new workers familiarize themselves with the construction environment and understand the procedures and precautions for pile hole construction. Through virtual training, construction workers can practice in a risk-free environment and become familiar with equipment operation and positioning processes.

[0024] In step S4, at the construction site, GPS, laser scanners, drones and other equipment are used to perform real-time positioning of pile holes. The GPS device connects to the BIM model in real time and compares the actual coordinates of each pile hole with the designed coordinates. The laser scanner can scan the entire construction site and quickly verify the position of the pile hole through high-precision scanning data to ensure the accuracy of positioning. The on-site positioning data is compared with the data in the virtual environment. If any position deviation is found, the system will automatically record and provide adjustment suggestions. If the actual pile hole position deviates, the construction personnel can enter the virtual environment through VR technology to adjust the position to ensure the accuracy of each pile hole during the construction process. With the automated monitoring system, the real-time position of each pile hole at the construction site can be displayed on the management platform through BIM+GIS technology, and engineers can check the construction progress at any time. When the pile hole position deviates, the system will automatically give an early warning signal and provide the best adjustment plan to help construction personnel correct it in time.

[0025] In step S5, all pile hole positioning data is stored on the cloud platform, creating an accuracy record archive for later verification and quality control. This data archive not only facilitates later acceptance but also provides a reference for future projects and optimizes construction methods. All design, construction, positioning, and virtual adjustment data are stored on the cloud platform, ensuring data integrity, traceability, and security. Project managers can view real-time construction progress, pile hole locations, construction quality, and positioning accuracy at any time through the management platform, providing a basis for later construction adjustments and acceptance.

[0026] In summary, the method proposed in this embodiment has the following advantages: 1. It improves pile hole positioning accuracy and reduces human error: Traditional pile hole positioning relies heavily on manual measurement and marking, which is easily affected by factors such as weather, environmental factors, and manual operation, resulting in large measurement errors. By integrating BIM and GIS, all design data is displayed in a three-dimensional virtual environment, allowing construction workers to more intuitively check the precise location of the pile hole. The GIS system also monitors the pile hole position in real time and further accurately locates it using GPS or differential GPS technology, reducing manual operation errors. Using VR technology, construction workers can quickly fine-tune the pile hole position in a virtual environment, making precise adjustments. This not only reduces deviations, but also allows each adjustment to be verified through virtual reality simulation, ensuring accurate pile hole positioning. By combining on-site laser scanners, drones, and other technologies for real-time monitoring of the pile hole, the system automatically detects deviations. If the pile hole deviates from the preset position, the system promptly issues warnings and provides adjustment suggestions, avoiding rework and material waste caused by errors. 2. It improves construction efficiency: By applying BIM, GIS, and VR technology, construction workers no longer need to conduct complex on-site measurements and repeated adjustments. Real-time simulation and optimization in a virtual environment can identify potential problems in advance and enable thorough verification before actual construction, saving significant time. Rapid adjustment and precise control of pile hole locations can significantly shorten construction cycles and reduce ineffective work. BIM models and GIS systems facilitate information sharing and collaboration on the construction site, allowing multiple construction teams to work from a unified data platform, resulting in a more coordinated and efficient construction process. Virtual reality can be used to assess every step of the construction process, allowing for proactive adjustments to prevent unexpected issues from impacting the overall progress. The integration of BIM, GIS, and VR provides real-time feedback during the construction process, helping construction personnel adjust plans at any time, avoiding delays and errors and ensuring on-time completion. 3. Improved construction quality and safety: Construction managers can leverage BIM and GIS technologies to monitor the exact location of pile holes, construction progress, and resource usage. All relevant data is synchronized in real time, ensuring controlled construction quality. Virtual reality technology can predict risks before construction begins, analyze potential hazards during construction, and implement timely measures to reduce the occurrence of safety incidents. Through VR simulation, construction workers can pre-test the pile hole construction process in a virtual environment, assessing the effectiveness of construction under different conditions (such as soil type and groundwater level), and thus optimize the construction plan. When potential risks arise, construction workers can make adjustments in the virtual environment to avoid accidents during actual construction. Virtual training through VR technology allows construction workers to familiarize themselves with on-site operating procedures and safety regulations, reducing accidents caused by improper operation. VR technology can also help novice workers better understand construction requirements and improve their operational skills.4. Resource Optimization and Cost Savings: Through the integration of BIM, GIS, and VR technologies, construction personnel can gain real-time insights into the specific construction site conditions, progress, and resource requirements, thus avoiding resource waste. Accurate pile hole positioning ensures optimal allocation of each construction resource, avoiding unnecessary resource consumption due to pile hole positioning errors. Simulating and optimizing the construction process with virtual reality technology can identify and correct potential problems before construction begins, reducing rework due to errors, design changes, or management oversights, avoiding the waste of multiple adjustments and repeated construction, and lowering construction costs. High-precision pile hole positioning eliminates material waste due to positional deviations during construction, ensuring that the construction materials used for each pile hole match actual requirements and avoiding the waste of excess concrete, rebar, and other materials. 5. Enhanced Construction Visualization and Communication: The combination of BIM and GIS allows every piece of construction project data to be presented in a three-dimensional virtual environment. Construction personnel, managers, designers, and other stakeholders can view the entire construction progress and the specific conditions of each pile hole on a unified platform, improving collaboration and communication between departments. Improve communication efficiency among construction teams: The application of virtual reality technology allows construction workers to view and adjust in real time in a virtual environment. Through intuitive three-dimensional views and virtual simulation, cross-departmental collaboration can be carried out more efficiently, the speed and accuracy of information transmission can be improved, and errors caused by information asymmetry or poor communication in traditional methods can be avoided. 6. Improve project traceability and management efficiency: The combination of BIM+VR+GIS enables all data, positioning information and adjustment records in the construction process to be stored and archived in real time and managed through the cloud platform. This provides a convenient basis for future project reviews, quality acceptance and rectification. By integrating the digital data of BIM and GIS systems, the construction process, maintenance phase, and even later repairs and renovations of the entire project can be seamlessly connected. This method not only provides real-time data during the construction process, but also continues to play a role after the completion of the project, facilitating long-term management and maintenance.
