Description

Technical Field

[0001] The present invention belongs to the technical field of tunnel drilling and blasting construction, and specifically relates to an intelligent construction method, system and complete set of intelligent construction equipment based on a BIM model. Background Art

[0002] Mechanized construction of tunnel drilling and blasting is necessary to ensure construction quality and reduce the labor intensity of operators. It can reduce mass casualties in tunnel construction, improve tunnel construction safety, reduce the number of operators in tunnel construction, and reduce the increasingly tight manpower demand. It is an important measure to ensure the progress of construction. Intelligent tunnel equipment is the core of realizing intelligent tunnel construction. Not only the construction equipment must be mechanized, but also intelligently mechanized to achieve the work goals of design, construction and evaluation, and to meet the requirements of new construction methods, new theories and new goals. Therefore, equipment manufacturers must develop intelligent equipment around intelligent tunnel construction, realize the collection of geological data, the storage of construction data and the unmanned control of equipment, and create a safer, more efficient, more reliable, more intelligent and more economical series of intelligent tunnel construction equipment.

[0003] BIM (Building Information Modeling) is hailed as a revolutionary technology for the productivity of the construction industry in the 21st century. It simulates the real information of a building through digital information simulation (including three-dimensional geometric shape information, and a large amount of non-geometric shape information, such as the material, weight, price and progress of building components, etc.). It integrates various relevant information of the construction project into an engineering data model. It is a detailed expression of the relevant information of the project, enabling designers and engineering technicians to respond correctly to various building information and provide a solid foundation for collaborative work.

[0004] At present, the mechanization and intelligence level of tunnel construction is backward, and the on-site management has high freedom and low efficiency, which is not conducive to tunnel safety and construction efficiency improvement. Therefore, some universities and construction units have begun to try to build intelligent auxiliary construction systems to monitor and analyze in real time, and predict and warn construction safety and equipment failures. For example, Patent No. 201710850756.9 proposes a shield tunnel intelligent construction auxiliary system based on big data technology and a method of use, including a basic management module, an analysis and processing module and an early warning module; the basic management module is connected to the analysis and processing module through a wireless network, and a database is set on the analysis and processing module to output parameter control or to warn through the early warning module; the basic management module includes equipment monitoring module, equipment management module, technical management module, quality management module, safety management module, material management module, and progress management module. The system can predict and warn the surrounding environment and stratum deformation, tunnel engineering quality and shield machine failure, reduce unsafe behaviors, improve equipment operation efficiency, tunnel construction safety and tunnel engineering quality, and reduce construction costs.

[0005] In addition, the industry has begun to try to use tunnel BIM tools to give full play to the advantages of engineering 3D design delivery. For example, in the Chinese invention patent application with patent application number 201710025805.5, a large-scale shield tunnel intelligent management system based on BIM and AI is proposed, including a time management subsystem to regulate and manage the overall construction progress and construction matters; a BIM management subsystem to plan and manage the spatial location and entry and exit of materials and equipment; an AI intelligent subsystem, based on the study of existing projects, predicts the resources required for future construction and optimizes resource allocation in advance. With time as the main line, the overall construction progress is regulated and managed, and people, machines and objects are deployed; with space as the basis, the BIM management subsystem is used to plan and manage the spatial location and entry and exit of materials and equipment; with data as the basis, the engineering information database is managed, and it is used as a learning resource for the AI ​​intelligent subsystem to continuously improve the level of intelligence. In this solution, the three systems are relatively independent, the BIM model has no timeline, the time management has no spatial concept, and AI learning can only achieve the optimization of resource allocation. The function is single and the entire construction process is not integrated.

[0006] The intelligent auxiliary construction system and BIM application management currently being tried in the industry are still immature and need to be further improved. For example, in the Chinese invention patent application with patent application number 201710850756.9, the intelligent construction auxiliary system and its use method proposed can collect data such as the surrounding environment, equipment operation, and construction progress, and use database analysis and comparison to make predictions and early warnings. However, the establishment of the system database requires the long-term accumulation of a large amount of data, and experience is used as the basis for judgment. When encountering special working conditions such as poor geology, the system will be difficult to handle, and the system is a passive alarm, and it is impossible to plan in advance, monitor feedback and modify the construction plan, and no closed-loop chain is formed. Summary of the invention

[0044] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the scope of protection of the present invention.

[0045] The application principle of the present invention is described in detail below in conjunction with the accompanying drawings.

[0046] Example 1

[0047] An embodiment of the present invention provides an intelligent construction method based on a BIM model, which specifically includes the following steps:

[0048] Step (1) constructing a tunnel BIM information model based on a preset construction plan (including construction tasks and construction plans);

[0049] Step (2) based on the tunnel BIM information model, automatically sending the construction task to the intelligent construction machine, and the intelligent construction machine automatically or guidedly completes the construction task;

[0050] Step (3) automatically monitors the construction quality data and construction process data of the intelligent construction unit, and feeds back the data to the tunnel BIM information model, optimizes the tunnel BIM information model, and forms a PDCA closed loop.

[0051] It can be seen that based on the intelligent construction method in the embodiment of the present invention, the entire tunnel drilling and blasting intelligent construction process is driven by the BIM information model to complete construction task planning, construction plan management, construction plan optimization and construction quality monitoring, thereby realizing safe, intelligent and efficient construction of tunnel engineering.

[0052] like Figure 1As shown, in a specific implementation of the embodiment of the present invention, the tunnel BIM information model includes a tunnel three-dimensional BIM model, a tunnel design BIM model, a tunnel construction BIM model and a tunnel operation and maintenance BIM model;

[0053] Based on the three-dimensional BIM model of the tunnel, construction geological information, design plan and construction plan are loaded to form the tunnel design BIM model;

[0054] Loading a construction plan based on the tunnel design BIM model to form the tunnel construction BIM model;

[0055] The construction process data is loaded based on the tunnel construction BIM module to form the tunnel operation and maintenance BIM model, which is used to guide operation and maintenance management after the tunnel construction is completed.

[0056] The method for constructing the three-dimensional BIM model of the tunnel includes:

[0057] Construct a three-dimensional model of the topography at the tunnel location;

[0058] According to the tunnel design drawings, three-dimensional tunnel conductor path design, tunnel section design and tunnel support structure design are carried out to complete the construction of the tunnel three-dimensional BIM model.

[0059] The method for constructing the tunnel design BIM model specifically includes:

[0060] Based on the three-dimensional BIM model of the tunnel, the three-dimensional BIM model of the tunnel is segmented using the geological section map and the geological layered surface;

[0061] The geological exploration and advanced geological forecast information are integrated into the segmented three-dimensional BIM model of the tunnel, and the two-dimensional design drawings are associated with the corresponding pile number, location, and model of the tunnel to design a plan. The key construction links or measures are imported into the three-dimensional visual construction plan to facilitate the rapid and accurate transmission of information and form the tunnel design BIM model. According to the tunnel design BIM model, the entire construction process can be simulated according to geological information, construction period requirements, etc., and the rationality of the construction plan can be planned and verified, including the whole engineering process simulation and the process simulation of the construction equipment in the key link tunnel reconstruction scene. The whole engineering process simulation is completely in accordance with the actual construction process of the tunnel. The process flow chart is built according to the model structure tree, the operation time of each process and the quantitative attributes of the model are set, and the resources such as equipment and personnel are associated. The order and operation time of each process are adjusted, and the cost, efficiency and other indicators of each plan are compared and analyzed to select the best construction plan; at the same time, the type, density, volume, quality and other attribute parameters of the tunnel design BIM model can be used to accurately calculate the machine material consumption, the engineering quantity statistics, and the cost budget in the design stage, so as to facilitate the reasonable and efficient development of the pre-construction preparation work. The process simulation of construction equipment integrated into the tunnel reconstruction scenario is mainly responsible for verifying the effectiveness of complete sets of intelligent equipment and stand-alone equipment. It uses a virtual tunnel construction scene built at a 1:1 ratio, and original-size construction equipment to simulate real operation actions, conduct equipment movement space interference inspection, cluster collaborative operation and construction method adaptability simulation, and at the same time simulate the operation sequence for a large number of repetitive actions such as drilling and wet spraying, compare and analyze the construction operation efficiency, and solve the problem that complex process construction can only be carried out by operators based on experience. According to the process simulation results of the whole project process and the process simulation of construction equipment integrated into the tunnel reconstruction scenario of key links, the construction plan Gantt chart (used as the time schedule axis of the construction process) is automatically generated. After manual inspection and confirmation, the tunnel design BIM model integrated with the construction plan is converted into a tunnel construction BIM model.

[0062] The BIM model for tunnel construction is used as the core driving source of the construction process. It carries topographic data, geological survey information, tunnel design drawings, tunnel construction plans, tunnel construction plan review and construction plan arrangement information. With the Gantt chart generated by process planning as the center, it automatically issues construction tasks to intelligent construction units and related auxiliary operators to automatically or guide the completion of construction work. For details, see Figure 2 .

[0063] Using the tunnel information BIM model, according to the process simulation and construction plan simulation results, the construction plan Gantt chart with construction equipment, personnel and materials is automatically generated to complete the planning and implementation plan of the whole tunnel construction task, and the tasks are automatically issued to the corresponding people, machines and materials in the order of the process, and the relevant resources are mobilized to carry out the task operation. The intelligent construction single machine automatically or guides the personnel to operate the construction;

[0064] During the operation process, an intelligent construction data management system is used to collect tunnel environmental data, construction unit operation parameters, and construction quality parameters of the construction process in real time, and send them to the tunnel information BIM model for optimizing the tunnel information BIM model.

[0068] The intelligent construction data management system automatically issues construction tasks to the intelligent construction stand-alone machine, and the intelligent construction stand-alone machine automatically or guidedly completes the construction tasks;

[0069] The intelligent construction data management system automatically monitors the construction quality data and construction process data of the intelligent construction unit, and feeds back the data to the tunnel BIM information model, thereby optimizing the tunnel BIM information model and forming a PDCA closed-loop cycle.

[0070] The tunnel BIM information model includes a tunnel three-dimensional BIM model, a tunnel design BIM model, a tunnel construction BIM model and a tunnel operation and maintenance BIM model;

[0071] Based on the three-dimensional BIM model of the tunnel, construction geological information, design plan and construction plan are loaded to form the tunnel design BIM model;

[0072] Loading a construction plan based on the tunnel design BIM model to form the tunnel construction BIM model;

[0073] The construction process data is loaded based on the tunnel construction BIM module to form the tunnel operation and maintenance BIM model.

[0074] The intelligent construction data management system automatically issues construction tasks to the intelligent construction stand-alone machine, and the intelligent construction stand-alone machine automatically or guides to complete the construction tasks, specifically:

[0075] The intelligent construction data management system uses the tunnel information BIM model to automatically generate a construction plan Gantt chart with construction equipment, personnel, and materials according to the process simulation and construction plan simulation results, completes the planning of the entire tunnel construction task and the formulation of the implementation plan, and automatically issues tasks to the corresponding people, machines, and materials in the chronological order of the process, mobilizes relevant resources to carry out task operations, and the intelligent construction unit automatically or guides personnel to operate the construction.

[0076] In the specific implementation process, Figure 4 As shown, the intelligent construction unit includes a complete set of intelligent construction equipment such as a multi-functional drilling rig, a rock drilling trolley, a wet spraying machine, an arch frame trolley, a waterproof board trolley, and a lining trolley.

[0077] In summary, during the entire tunnel construction process, real-time analysis is used to import, collect information and output the construction quality of the previous cycle to optimize the construction plan for the next cycle. After the intelligent construction stand-alone operation, the construction quality data is collected again and feedback is given again. This cycle is repeated continuously to form a PDCA closed-loop optimization and improvement chain for the construction plan, continuously improving the safety, quality and efficiency of tunnel construction and reducing construction costs.

[0078] The intelligent construction data management system stores the correspondence between construction plans and construction quality in real time, accumulates a large amount of real data of the construction process, automatically learns and practices, and establishes an intelligent expert database for construction plans. The intelligent construction unit of the tunnel drilling and blasting method is the executor of the intelligent construction data management system.
