Description

Technical Field

[0001] This invention belongs to the field of road construction technology, and specifically relates to a road construction device and method based on UAV BIM technology for the entire construction process. Background Technology

[0002] Road engineering is a core component of infrastructure construction. Road construction in complex terrain (such as mountainous areas) and large construction areas presents significant challenges due to complex geological conditions, significant topographical variations, long routes, and limited available road access. Currently, road engineering surveying, design, and construction primarily rely on traditional techniques, as detailed below: In the surveying stage, traditional surveying techniques require a large number of surveyors to conduct field surveys to obtain topographic data, providing a basis for road design. In the design stage, the selection of road alignment mainly relies on the experience of designers combined with the results of field surveys, referring to relevant specifications and standards to conduct two-dimensional plan design, and using two-dimensional contour maps to carry out the design of road plan, longitudinal section and cross section. In the construction stage, on-site construction is carried out by manually referring to the design drawings, and the progress tracking, cost accounting and safety management during the construction process also mainly rely on manual recording and analysis.

[0003] With technological advancements, UAV surveying and BIM (Building Information Modeling) technologies have been gradually applied in the engineering field. UAV surveying, with its flexibility, convenience, and strong applicability, can overcome the limitations of harsh environments, reduce labor costs, and complete surveying tasks based on remote sensing technology. BIM technology simulates the real information of engineering entities through digital information, possessing characteristics such as information completeness, relevance, consistency, visualization, coordination, simulation, optimization, and drawing output. It can realize the early simulation and rehearsal of engineering construction content, avoid engineering collisions and overlaps, and achieve integrated management of design and construction. Some projects have attempted to use UAV technology to model the site terrain, providing topographic and data support for road design, or to use BIM technology to model engineering entities. However, the two have not yet formed a deeply integrated technological system, making it difficult to apply to the entire construction process of road engineering. Summary of the Invention

[0004] The purpose of this invention is to provide a road engineering construction device and method based on UAV BIM technology to solve the problems of insufficient integration of UAV and BIM technology and low level of intelligence, thereby building a technical system that deeply integrates the two, realizing digital and intelligent management of the entire process of road engineering design, construction, cost, schedule and safety, and adapting to the development trend of the engineering industry.

[0005] To address the aforementioned technical problems, this invention provides a road engineering construction device based on UAV BIM technology, comprising a UAV body, a shooting sensor, a data processing module, a BIM modeling and design module, and a professional calculation module. The various parts are logically connected to form a complete data transmission and working closed loop. The main body of the drone is a DJI drone, which serves as a data collection carrier and is used to carry out aerial photography operations with shooting sensors. The shooting sensors are single or multiple and are detachably mounted on the main body of the drone. They are used to shoot ground features from one vertical direction and four tilt directions to collect topographic and geomorphological image data of the project area. The data processing module includes ContextCapture Center software and ArcGIS software. ContextCapture Center software is used to optimize, correct, and visually reconstruct 3D reality models from aerial image data. ArcGIS software is used to process construction progress data and fit it with BIM modeling. The BIM modeling and design module includes REVIT software and CNCCBIM OpenRoads software. REVIT software is used to perform BIM modeling of engineering entities and road design schemes. CNCCBIM OpenRoads software is used to extract and transform terrain data obtained by UAV oblique photography to assist in the horizontal, vertical and horizontal design of roads. The specialized calculation module is used to calculate and verify the adjusted road design scheme model, generate construction drawings, and assist in calculating earthwork volume.

[0006] Preferably, the shooting sensor is detachably connected to the main body of the drone, and the image data collected by the main body of the drone is transmitted to the data processing module via wireless transmission or wired import.

[0007] Preferably, the 3D reality model data processed by the data processing module is imported into the BIM modeling and design module, and the engineering entity model and road design model generated by the BIM modeling and design module are fused and verified with the 3D reality model.

[0008] Preferably, the design model generated by the BIM modeling and design module is imported into the professional calculation module for verification, and the construction design drawings output by the professional calculation module are used to guide on-site construction; during the construction process, the progress data collected by the UAV is processed by ArcGIS software and then fitted with the BIM model to realize progress tracking and engineering quantity calculation.

[0009] This invention also provides a method for the entire construction process of road engineering based on UAV BIM technology, comprising the following steps: Step A: Preliminary preparation and scheme design; Step A1: Based on the characteristics of the project, consult relevant technical documents and standards to determine the technical requirements for various tasks, such as measurement accuracy and design parameters; conduct a comprehensive investigation and analysis of the project design drawings and on-site construction conditions, formulate a preliminary construction plan, organize relevant professional and technical personnel to conduct demonstration and analysis of the preliminary plan, optimize and improve it based on the demonstration results, and determine the final construction plan; Step B: Drone data collection; Step B1: Using drone oblique photography technology, drones equipped with one or more shooting sensors are used to take omnidirectional pictures of the features along the shooting route from one vertical direction and four oblique directions to collect complete topographic and geomorphological image data of the project area. Step B2: Import the collected aerial image data into ContextCapture Center software for image optimization and correction, complete the visual reconstruction of the 3D real scene model, and obtain the 3D terrain and landform model of the project area. Step C: BIM modeling; Step C1: Use Revit software to create a BIM model of the road engineering entity, generating an engineering entity BIM model. Import the engineering entity BIM model into the 3D real-world terrain model obtained in Step B. Use the collision detection function of the BIM software to comprehensively check the planar position of the road engineering entity, checking for conflicts with the positions of ditches, rivers, and large obstacles on site one by one. If conflicts exist, adjust the position and orientation of the engineering entity model in a timely manner. After the check is completed, confirm that the engineering entity model is fully adapted to the site conditions to avoid conflicts in later construction. At the same time, verify the modeling accuracy to ensure that the model parameters are consistent with the actual site data, providing accurate model support for subsequent design stages. Step C2: The CNCCBIM OpenRoads software is used to extract, transform, and optimize the terrain data acquired by UAV oblique photography. Core data such as terrain elevation, slope, and aspect are extracted. Combined with site conditions and road design specifications, a comprehensive analysis of the terrain data is conducted to assist in the horizontal, vertical, and cross-sectional design of the road project. Design parameters such as road alignment, longitudinal slope, and curve radius are input, and road plan, longitudinal, and cross-sectional designs are carried out sequentially. A road corridor model is established, and the road alignment is optimized to ensure that the design parameters comply with vehicle safety regulations. After constructing a complete 3D BIM model of the road project, collision detection and design parameter verification are performed. Once it is confirmed that there are no design deviations and no conflicts with the site terrain and engineering entities, the 3D design phase is completed. Step D: Construction drawing design; Step D1: Import the 3D BIM model of the road project adjusted in Step C into the professional calculation module, perform comprehensive calculation and verification of design parameters such as road structure strength, slope stability, and bearing capacity, and generate formal construction design drawings after confirming that the design scheme meets the relevant specifications and on-site construction requirements and has no design loopholes. Step D2: Export the relevant parameters of road coordinates and elevations for each road section from the 3D BIM model of the road project, and prepare construction layout drawings and construction technical briefing documents; combine the construction design drawings and technical briefing documents to guide on-site construction personnel in layout construction, equipment debugging and construction process deployment, so as to achieve precise connection between design and construction, avoid construction deviations, and ensure that the construction process meets the design requirements; Step E: Construction phase; Step E1: The project will carry out on-site construction according to the construction design drawings and construction technical briefing documents. During the construction process, drones will be used to collect on-site construction progress data at fixed intervals. The collected data will be processed and optimized by ArcGIS software and then fitted with the 3D BIM model of the road project to form an intuitive image of the project progress and analysis table. The construction progress of each road section will be tracked in real time, and construction delays will be identified by comparing with the planned progress. The construction plan will be adjusted in a timely manner. Step E2: After simultaneously using BIM technology to design the scheme on the natural ground, the natural ground and the planned terrain are overlaid and calculated to quickly obtain the earthwork volume for excavation and backfilling of the project. This volume is then double-checked with the actual earthwork volume measured on site to ensure that the earthwork volume calculation error is controlled within 5%. During construction, construction quality is simultaneously controlled. The construction process and parameters are compared in real time using the BIM model to correct construction deviations in a timely manner, ensuring that the construction quality meets the specifications and achieving coordinated control of construction progress, cost, and quality.

[0010] Preferably, in step B, the drone aerial photography altitude is set to 50-80m, the shooting overlap is 80%, the measurement accuracy is controlled within ±5cm, and the resolution of the three-dimensional real scene model reconstruction is 0.1m.

[0011] Preferably, the road design parameters in step D include a longitudinal slope of no more than 8% and a minimum curve radius of no less than 30m, to ensure that the road design meets the requirements of vehicle safety passage regulations.

[0012] Preferably, in step E, the drone collects construction progress data once a week, and the professional calculation software is PKPM software.

[0013] Preferably, the drone is a DJI M300 drone, with three high-definition cameras; the ContextCapture Center software version is 4.5, the ArcGIS software version is 10.8, the Revit software version is 2024, and the CNCCBIM OpenRoads software version is 2023.

[0014] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include: 1. This invention breaks through the limitations of conventional surveying techniques in applying two-dimensional modeling after measurement, transforming topographic maps into three-dimensional real-world models, achieving intuitive presentation and precise positioning of terrain and landforms; compared with traditional manual surveying, UAV oblique photography technology can quickly complete the surveying work of complex terrain and large construction areas, greatly shortening the surveying cycle, improving work efficiency, reducing the input of surveying personnel, reducing the risk of field operations, and improving measurement accuracy, providing high-precision data support for design. Referring to relevant application cases, the measurement efficiency can be improved by more than 50%, and the measurement accuracy can reach the standard requirement of 1:500. 2. This invention creates a brand-new road engineering design and construction mode, transforming traditional two-dimensional planar design into precise design under a three-dimensional real-scene model, making design parameters and related content more accurate; the deep integration of BIM model and three-dimensional real-scene topographic map can avoid conflicts between valleys, rivers, obstacles and the main road route in advance, avoiding secondary design adjustments and construction rework in the later stage. At the same time, parameters such as road longitudinal slope and curve radius are set according to the specifications, effectively ensuring driving safety; 3. This invention utilizes drone BIM technology to accurately calculate the earthwork volume for excavation and backfilling in advance, completing the quantity calculation and providing a scientific basis for cost control, effectively reducing construction costs. The shortened measurement cycle, reduced design adjustments, and visualized management of the entire construction process significantly accelerate construction progress and mitigate the risk of construction delays. Compared to traditional technologies, it can shorten the construction cycle by 20%-30% and save over 10% in construction costs. 4. This invention constructs a road engineering construction technology system that deeply integrates UAVs and BIM technology, solving the problems of insufficient integration and low level of intelligence between the two. It realizes digital and integrated management and control of the entire process of road engineering design, construction, cost, schedule and safety, which is in line with the development trend of digitalization and integration in the engineering industry. It can promote the application of smart construction mode in the field of road engineering, while creating project highlights and enhancing the company's industry influence.

During the construction process, the construction quality is controlled simultaneously. The construction procedures and parameters are compared in real time using the BIM model to correct construction deviations in a timely manner, ensuring that the construction quality meets the specifications and achieving coordinated control of construction progress, cost, and quality. Step F: Project Validation and Summary; Step F1: Track and verify the entire project implementation process, record the technical parameters, construction effects, cost control, and progress completion during construction.
