Description

Technical Field

[0001] The present invention relates to the technical field of pipeline construction, and in particular to a method for analyzing pipeline construction data based on BIM. Background Art

[0002] The integrated support and hanger for building pipelines is a device used for the installation and fixation of pipelines such as building water pipes, cables, and air-conditioning ventilation pipes. As an indispensable part of the building electromechanical field, the design of the integrated support and hanger has been ignored, and construction can only be carried out according to the general requirements described in the national standard atlas and more project construction site experience. With the progress and development of building design technology, there are more and more buildings with complex shapes and structures, and various special-shaped and curved shapes are everywhere. The internal informatization uses of buildings are also becoming more extensive and high-end, making the electromechanical integration systems inside these special-shaped buildings extremely complex. Due to the difficulty of the traditional project management method in efficiently processing such a complex electromechanical integration system, problems such as low engineering quality, low project efficiency, and miscommunication and omission of information have emerged in an endless stream, which has become a major problem in the construction quality of the current electromechanical system.

[0003] The traditional assembly method of the integrated support and hanger for electromechanical pipelines is to first collect the electronic drawings of each system and synthesize them into an initial electronic comprehensive pipeline layout drawing. Key points at dense pipeline layout parts are intercepted from the synthesized layout drawing, and a preliminary partial comprehensive pipeline support and hanger sectional layout drawing is drawn and positioned. The design of each local section can be determined according to the adjusted layout result of the integrated pipeline support and hanger, and finally the final electronic comprehensive pipeline support and hanger layout drawing is synthesized for the parties participating in the construction to confirm or approve for implementation. In addition, the various pipelines of the electromechanical system are extremely complex, and the pipeline routes are densely intertwined. If collisions occur during construction, demolition and rework phenomena will occur, and even the design scheme will be modified again, which not only wastes materials but also results in relatively low construction efficiency of the integrated pipeline support and hanger.

[0004] Currently, BIM technology has been introduced into some construction projects, providing a good technical platform and solution for the realization of integrated design and construction through a three-dimensional collaboration platform and a visual information transmission method. In such projects, using BIM technology for the integrated layout of pipeline supports and hangers can quickly improve the construction detail design and node design.

[0005] Chinese Patent Application Publication No. CN112733229A discloses a design method for mechanical and electrical integrated pipeline supports and hangers based on BIM technology, including the following steps: (1) creating a library of support and hanger components; (2) importing the components obtained in step (1) into BIM software for 3D modeling; (3) after the 3D modeling in step (2) is completed, adjusting and optimizing the 3D model of the support and hanger according to relevant construction specifications and mechanical property analysis, and completing the layout, force calculation and product selection of the support and hanger; (4) generating part drawings and assembly drawings of each component according to the adjusted and optimized layout drawing of the support and hanger, and realizing factory prefabrication production based on this; (5) constructing and installing on-site according to the drawings.

[0006] The prior art has the following problems: directly generating part drawings and assembly drawings of each component for prefabrication production according to the layout drawing of the support and hanger, and constructing on-site according to the drawings. However, in actual construction, various pipelines are intricate, the pipeline routes are densely intertwined, and the construction sequence is chaotic, making it difficult to ensure the construction efficiency during the assembly process.

[0050] Compared with the prior art, the beneficial effects of the present invention are as follows. The present invention constructs a BIM integrated support and hanger model by integrating pipeline construction information and building structure information, which can intuitively present the spatial relationship between the integrated support and hanger, pipelines, and building structures. Through modular processing, the complex BIM integrated support and hanger model is decomposed into several independent modules, and determining the key module features can reduce the amount of data processing and improve the data processing efficiency. By generating a dynamic collision rule set based on the key module features, it can adapt to different project requirements, improve the accuracy and comprehensiveness of collision detection, avoid conflicts between the integrated support and hanger and the building structure and pipelines during construction, and ensure the construction quality and efficiency. By accurately positioning the collision abnormal nodes and determining the integrated support and hanger path in combination with the connection constraint conditions, it provides an effective solution to solve the collision problem, avoids randomly adjusting the position of the support and hanger and affecting the overall structural stability and pipeline function, and improves the construction efficiency and quality. Adjust the pipeline construction information according to the integrated support and hanger path to generate a prefabricated component information library, realize the optimization of construction information. The prefabricated component information library includes the prefabricated component structure and assembly method, provides detailed guidance for prefabrication, improves the production efficiency and quality of prefabricated parts, reduces the on-site processing workload, and further improves the construction efficiency and construction accuracy. Determine the construction plan according to the prefabricated component information library and the building structure information, clarify the construction priority of each prefabricated component, reasonably arrange the construction sequence, avoid construction chaos, and improve the construction efficiency and construction accuracy.

[0051] Furthermore, the present invention constructs a pipeline layout model based on pipeline construction information, converts abstract pipeline construction information into an intuitive pipeline layout model, can clearly display the direction, diameter, connection relationship, etc. of various pipelines, can intuitively evaluate the rationality of pipeline layout, and provide a reliable basis for the formulation of construction plans. Constructing a BIM building model based on building structure information can accurately present the structural system of the building and ensure the rationality of the construction process. Model integration is performed based on the pipeline layout model and the BIM building model to construct a BIM comprehensive support and hanger model, comprehensively consider the characteristics of pipelines and building structures, optimize the design and layout of comprehensive supports and hangers, reduce construction errors, and improve construction efficiency and quality.

[0052] Furthermore, the BIM comprehensive support and hanger model is relatively complex, covering many support and hanger components and related information with pipelines and building structures. It is divided into several adaptation modules, and the large and complex model is decomposed into smaller and more manageable modules to improve the targeted construction. By extracting the features of each adaptation module, the detailed information of each module can be fully analyzed to provide data support for optimized design. The key module features are determined based on the correlation between the features of each module, which can improve the accuracy of determining the key module features and ensure the construction quality.

[0053] Furthermore, the present invention determines feature reference values based on key module features and preset module features, and thereby determines a number of candidate dynamic collision rules. This can not only avoid missing collision rules, determine corresponding dynamic collision rules from multiple dimensions, but also adapt to dynamic changes in projects and improve the scientific nature of the rules.

[0054] Furthermore, the present invention can accurately locate the root cause of the collision problem by analyzing the node characteristics of the abnormal collision node, thereby determining the connection constraint conditions of the abnormal collision node, providing clear restrictions and guidance for the subsequent determination of the comprehensive support and hanger path, ensuring that the adjusted comprehensive support and hanger path meets safety and functional requirements, avoiding collision problems, and improving construction efficiency.

[0055] Furthermore, the present invention achieves the refinement and standardization of construction tasks by decomposing the comprehensive support and hanger path into several prefabricated units. Each prefabricated unit can be prefabricated in the factory, reducing the time and workload of on-site construction. The prefabricated units are produced in the factory, the production environment is stable, and the quality control is more stringent. Compared with on-site construction, the factory can use more advanced production equipment and processes to ensure the accuracy and quality of prefabricated components. Assembly compatibility verification before the production of prefabricated units can detect possible assembly problems between prefabricated components in advance. Through early verification, it can be ensured that the prefabricated components can be assembled smoothly on site, thereby improving construction efficiency.

[0056] Furthermore, by determining the topological dependency relationships of each prefabricated component, the present invention can clearly understand the sequence of each component during the construction process. Based on the topological dependency relationships of each prefabricated component and the construction complexity of each prefabricated component, a priority scoring model is constructed, which helps to formulate a more scientific construction priority for each prefabricated component in the comprehensive support and hanger. According to the priority score, the components with high priority are arranged in the early stage of construction or on the critical path and are given priority in construction, which can ensure that the critical path of the entire construction project is not delayed and improve the construction efficiency and accuracy.

[0065] Please refer to Figure 1 as shown in the figure, which is a flowchart of the BIM-based pipeline construction data analysis method according to the embodiment of the present invention; the embodiment of the present invention provides a BIM-based pipeline construction data analysis method, including:

[0066] Step S1, obtaining pipeline construction information and building structure information, and constructing a BIM integrated support and hanger model;

[0067] In implementation, the pipeline construction information includes pipeline routing, pipe diameter, material, connection method, construction technology (including welding process parameters, pipeline insulation practices, grounding methods of electrical circuits, etc.), equipment information related to the pipeline (including models, specifications, dimensions, interface forms, and technical parameters of equipment such as pumps, fans, and air conditioning units), and material information required for pipeline construction (including specifications, models, quantities, quality standards, etc.) of materials. The building structure information includes building design drawing information (including overall building floor plans, elevation views, sectional views, etc.), building structure information (including floor plans, reinforcement drawings, foundation plans, etc. of the building structure, which can reflect the dimensions, reinforcement, material strength grades, embedment depths, etc. of components such as beams, slabs, columns, and walls of the building structure), geological information (including soil type, bearing capacity, groundwater level, etc.), and building function information (different building usage functions have different requirements for pipelines and structures. For example, hospital buildings have extremely high requirements for the reliability and stability of medical gas pipelines and electrical equipment; industrial buildings have special requirements for the bearing capacity and spatial layout of the structure according to the needs of the production process).

[0068] Please refer to Figure 2 as shown in the figure, which is a schematic flowchart of constructing a BIM integrated support and hanger model according to the embodiment of the present invention; specifically, in the step S1, constructing a BIM integrated support and hanger model includes:

[0069] Step S11, constructing a pipeline layout model based on the pipeline construction information;

[0070] Step S12, constructing a BIM building model based on the building structure information;

[0071] Step S13, integrating the models based on the pipeline layout model and the BIM building model to construct a BIM comprehensive support and hanger model.

[0072] It is understandable that there is no specific limitation on the specific method or modeling software for constructing the pipeline layout model, BIM building model, and BIM comprehensive support and hanger model. For example, using BIM software such as Autodesk Revit and Bentley Systems, pipeline construction information, optimization goals, and constraints are used as inputs, and the optimal pipeline layout solution is solved based on the ant colony algorithm to construct a pipeline layout model. The optimization goals include the shortest total length of pipelines and the smallest spacing between pipelines. The constraints include the minimum force on pipelines and the minimum resource consumption of pipelines. The pipeline layout model and the BIM building model are integrated, and a structural force analysis is performed. Based on the force analysis results, a BIM comprehensive support and hanger model is constructed.

[0073] The present invention constructs a pipeline layout model based on pipeline construction information, converts abstract pipeline construction information into an intuitive pipeline layout model, can clearly display the direction, diameter, connection relationship, etc. of various pipelines, can intuitively evaluate the rationality of pipeline layout, and provide a reliable basis for the formulation of construction plans. Constructing a BIM building model based on building structure information can accurately present the structural system of the building and ensure the rationality of the construction process. Model integration is performed based on the pipeline layout model and the BIM building model to construct a BIM comprehensive support and hanger model, comprehensively consider the characteristics of pipelines and building structures, optimize the design and layout of comprehensive supports and hangers, reduce construction errors, and improve construction efficiency and quality.

[0074] Step S2, modularizing the BIM comprehensive support and hanger model and determining key module features;

[0075] Specifically, the step S2 includes:

[0076] Step S21, dividing the BIM comprehensive support and hanger model into a plurality of adaptation modules based on a preset division rule;

[0077] Step S22, extracting features from each of the adaptation modules to obtain a number of module features;

[0078] Step S23, determining key module features based on the association relationship between the module features.

[0079] During implementation, actual implementers can set preset division rules according to actual conditions or based on building functional areas, spatial locations, connection methods, carrying capacity, etc., to ensure the integrity of the divided adaptation modules, clear boundaries between the adaptation modules and reasonable connection methods.

[0080] It can be understood that by clustering each adaptation module based on a clustering algorithm, several clustering sets are obtained. Each clustering set includes at least one adaptation module. Based on the similar features of the adaptation modules in each clustering set, several module features are determined. Based on each module feature, a feature association matrix is constructed, and the correlation coefficients between each module feature are calculated (if the correlation coefficient between two features is relatively high (0.9 - 0.95), it indicates a strong positive correlation between them; if the correlation coefficient is close to -1 (-0.9 - -0.95), it indicates a strong negative correlation), and a feature association graph is drawn. In the association graph, each feature is represented by a node, the connection between nodes represents the association relationship between features, and the length of the connection between nodes represents the correlation coefficient, so as to determine the key module features (the number of connections is greater than 1 / 3 - 1 / 5 of the total number of connections, and the connection length is greater than 2 - 3 times the average connection length).

[0081] Specifically, the BIM integrated support and hanger model is relatively complex, covering numerous support and hanger components as well as the associated information with pipelines and building structures. It is divided into several adaptation modules, breaking the huge and complex model into smaller and more manageable modules, improving the construction pertinence. By extracting features from each adaptation module, the detailed information of each module can be comprehensively analyzed, providing data support for the optimization design. Determining the key module features based on the association relationship of each module feature can improve the accuracy of determining the key module features and ensure the construction quality.

[0082] Step S3, generate a corresponding dynamic collision rule set based on the key module features, perform multi-dimensional collision tests on the BIM integrated support and hanger model based on the dynamic collision rule set, and determine whether the collision test results meet the preset standards;

[0083] Specifically, in the step S3, generating a corresponding dynamic collision rule set based on the key module features includes:

[0084] Step S31, determine a feature reference value based on the key module features and preset module features;

[0085] Step S32, determine several candidate dynamic collision rules based on the feature reference value and the dynamic collision model;

[0086] Step S33, screen each of the candidate dynamic collision rules based on the key module corresponding to the key module features to obtain a dynamic collision rule set.

[0087] In implementation, according to the key module features Y1, Y2,..., Y j ,..., Y m and the preset module features E1, E2,..., E j ,..., E mDetermine the characteristic reference value P, where P = (∑ m j=1 Y j × E j ) / (sqrt(∑ m j=1 (Y j ) 2 ) × sqrt(∑ m j=1 (E j ) 2 ))), where sqrt() is a preset square root determination function, j = 1, 2,..., m, and m is the number of eigenvalue within the module characteristics.

[0088] It can be understood that the actual implementer can determine the preset module characteristics based on the actual situation or the module characteristics that pass the qualification test in the historical data. The actual implementer can determine the sample training set based on the characteristic reference value determined from the historical data and the dynamic collision rules that pass the qualification test, and train the neural network model based on the sample training set to obtain a dynamic collision model. Input the characteristic reference value into the dynamic collision model to obtain several candidate dynamic collision rules output by the dynamic collision model.

[0089] It can be understood that each candidate dynamic collision rule is screened through the comprehensive hanger layout, pipeline layout, and building structure characteristics of the key module corresponding to the key module characteristics, and the candidate dynamic collision rules that do not conform to the actual situation are screened out to obtain a dynamic collision rule set.

[0090] The present invention determines the characteristic reference value based on the key module characteristics and the preset module characteristics, and determines several candidate dynamic collision rules accordingly. It can not only avoid missing collision rules, determine the corresponding dynamic collision rules from multiple dimensions, but also adapt to the dynamic changes of the project and improve the scientificity of the rules.

[0091] Specifically, in the step S3, it further includes:

[0092] Step S34, if the collision test result meets the preset standard, determine several adapted prefabricated units based on each of the adapted modules;

[0093] Step S35, determine the assembly compatibility of each adapted prefabricated component within each of the adapted prefabricated units based on the topological correlation degree between the adapted prefabricated units;

[0094] Step S36, if the assembly compatibility of each of the adapted prefabricated components meets the assembly standard, generate a corresponding information library of the adapted prefabricated components.

[0095] Specifically, the step S35 includes:

[0096] Step S351: Construct a topological association model based on the spatial association relationship, functional association relationship, and process association relationship among the respective adaptation prefabricated units;

[0097] Step S352: Determine the topological association degree among the respective adaptation prefabricated units based on the topological association model;

[0098] Step S353: Determine the assembly compatibility of each adaptation prefabricated component within each adaptation prefabricated unit based on the topological association degree among the respective adaptation prefabricated units and the compatibility index model.

[0099] In implementation, the collision test result meets the preset standard, that is, the collision result is zero collision. There is no limitation on the method for constructing the topological association model. For example, methods such as graph theory analysis, network analysis, or deep learning can be used. Based on factors such as the connection tightness, distance, and functional dependence among the respective adaptation prefabricated units, corresponding weights are assigned. For example, the weight between units with a tight connection and a large functional association is relatively high, so as to quantify the topological association degree. By calculating indicators such as the shortest path and connection strength among the respective adaptation prefabricated units, the topological association degree among the respective adaptation prefabricated units is obtained. For example, the Dijkstra algorithm is used to calculate the shortest path between nodes. The shorter the path and the higher the connection strength, the higher the topological association degree.

[0100] It can be understood that the actual implementer can train the machine learning model based on the topological association degree and assembly compatibility relationship among the adaptation prefabricated units in the historical data to obtain the compatibility index model. Inputting the obtained topological association degree among the respective adaptation prefabricated units into the compatibility index model can obtain the assembly compatibility of each adaptation prefabricated component within each adaptation prefabricated unit. The assembly compatibility includes interface matching (whether the interface types, sizes, positions, etc. of each adaptation prefabricated component match), reasonable spatial layout (no conflict in space during installation, with sufficient operation and maintenance space), and functional coordination (for example, in the ventilation system prefabricated unit, check whether the air volume and air pressure of the fan component and the air duct component match to ensure the normal operation of the ventilation system).

[0101] It can be understood that the actual implementer can set the assembly standard based on the actual situation or based on the assembly process that has passed the qualification test in the historical data. If the assembly compatibility of each adaptation prefabricated component meets the assembly standard, a corresponding adaptation prefabricated component information library is generated, including the name, model, specification, material, bearing capacity, load information, manufacturer, assembly requirements (including assembly position, sequence, connection method, fittings), topological association relationship, etc. of the adaptation prefabricated component.

[0102] Step S4: If the test result does not meet the preset standard, determine the collision abnormal node based on the test result, and determine the comprehensive support and hanger path based on the connection constraint condition of the collision abnormal node;

[0103] Please refer to Figure 3 as shown, which is a schematic flow chart for determining the path of the integrated support and hanger in an embodiment of the present invention; specifically, in the step S4, determining the path of the integrated support and hanger includes:

[0104] Step S41, determining the connection constraint conditions of the collision abnormal node based on the node characteristics of the collision abnormal node;

[0105] Step S42, determining the path of the integrated support and hanger based on the connection constraint conditions of the collision abnormal node.

[0106] In implementation, if the test result does not meet the preset standard, it indicates a collision situation, and then the collision position, that is, the collision abnormal node, is determined. The node characteristics of the collision abnormal node include the size information of the support and hanger and related pipelines at the collision abnormal node, such as pipe diameter, length, cross-sectional size of the support and hanger rods, etc.; the coordinate position of the node in the three-dimensional space, clarifying its specific position in the building structure; the material types of the support and hanger and pipelines at the collision abnormal node, and the mechanical properties (such as yield strength, tensile strength) of different materials will affect the connection method and bearing capacity; the existing connection forms at the collision abnormal node, such as the specifications, quantities, and spacings of bolts in bolt connection, and the types and lengths of welds in welded connection.

[0107] It can be understood that the connection constraint conditions include connection strength constraint, connection method constraint, connection size and tolerance constraint, and installation process constraint. Connection strength constraint: According to the force conditions of the support and hanger and the pipeline and the mechanical properties of the material, calculate the minimum strength required at the connection part. For example, through mechanical analysis, it is determined that the tensile strength at the connection part of a certain support and hanger node needs to reach X MPa when bearing the self-weight and vibration load of the pipeline, and this is used as the connection strength constraint condition. Connection method constraint: Combining the geometric characteristics and spatial positions of the nodes, determine the feasible connection methods. For example, in areas with narrow space and high appearance requirements, riveting or concealed bolt connection can be specified; for parts that need to be disassembled and maintained frequently, detachable bolt connection is used. Connection size and tolerance constraint: According to the sizes of the support and hanger and the pipeline, determine the size requirements of the connection components and the allowable tolerance range. For example, it is stipulated that the diameter tolerance of the connection bolt is within ±0.5 mm to ensure the tightness and reliability of the connection. Installation process constraint: Considering the on-site construction conditions and the operation skills of the workers, determine the reasonable installation process requirements. For example, for some complex welded connections, it is required to use professional welding equipment and trained welders for operation, and specify process parameters such as the preheating temperature before welding and the heat preservation time after welding.

[0108] It can be understood that by prioritizing each specific constraint condition based on the connection constraint conditions, since the constraint conditions have a greater impact on the safety and functionality of the pipe supports and hangers, higher priorities should be given to them. For example, the connection strength constraint usually has a higher priority because it directly relates to whether the pipe supports and hangers can normally carry the pipeline; while some constraint conditions regarding appearance have relatively lower priorities. After determining the priorities, when determining the path of the pipe supports and hangers, the high-priority constraint conditions can be preferentially satisfied.

[0109] It can be understood that by referring to the building structure drawings, analyzing the positions of beams, columns, walls, etc. of the building structure, and avoiding conflicts between the path of the pipe supports and hangers and the structural components. When installing pipe supports and hangers under the beam or beside the column of the building structure, the bearing capacity and stability of the structure should be considered to ensure that the installation of the pipe supports and hangers will not damage the building structure. Starting from the collision abnormal nodes, according to the overall trend and layout of the pipeline, initially plan the path of the pipe supports and hangers. The path of the pipe supports and hangers should be as consistent as possible with the pipeline trend, reducing unnecessary turns and bends to reduce the complexity of the forces on the pipe supports and hangers. For example, for horizontally laid pipelines, the path of the pipe supports and hangers should also be kept as horizontal as possible; for vertically rising or falling pipelines, the path of the pipe supports and hangers should be perpendicular to them. When initially planning the path of the pipe supports and hangers, continuously check whether the path meets the connection constraint conditions. For example, when selecting the installation position of the pipe supports and hangers, ensure that there is enough space for the specified connection operations to meet the requirements of the connection method and installation process. If welding connection is used, the installation position should be convenient for welders to operate, and the surrounding environment meets the welding safety requirements. Use structural mechanics analysis software to analyze the mechanical properties of the initially planned path of the pipe supports and hangers, calculate the forces on the pipe supports and hangers under various loads, such as stress, strain, and deformation, etc. According to the analysis results, adjust the path of the pipe supports and hangers to make the forces on the pipe supports and hangers more uniform and reasonable, and avoid stress concentration areas. Optimize the construction process of the path of the pipe supports and hangers to reduce the construction difficulty and construction time and lower the construction cost.

[0110] By analyzing the node characteristics of the collision abnormal nodes, the present invention can accurately locate the root cause of the collision problem, thereby determining the connection constraint conditions of the collision abnormal nodes, providing clear limitations and guidance for subsequent determination of the integrated pipe support and hanger path, ensuring that the adjusted integrated pipe support and hanger path meets the safety and function requirements, avoiding collision problems, and improving construction efficiency.

[0111] Step S5: Adjust the pipeline construction information based on the integrated pipe support and hanger path, and generate a corresponding prefabricated component information library based on the adjusted pipeline construction information and the building structure information, including the structures and assembly methods of each prefabricated component;

[0112] Specifically, in the step S5, generating a corresponding prefabricated component information library based on the adjusted pipeline construction information and the building structure information includes:

[0113] Step S51: Decompose the integrated support and hanger path based on the adjusted pipeline construction information and the building structure information to obtain a number of prefabricated units.

[0114] Step S52: Verify the assembly compatibility of each prefabricated component in each prefabricated unit based on preset verification conditions.

[0115] Step S53: If the assembly compatibility of each prefabricated component meets the assembly standard, generate a corresponding prefabricated component information library based on each prefabricated component.

[0116] In implementation, the actual implementers can set the preset verification conditions based on the actual situation or the assembly compatibility conditions that have passed the qualification test in historical data.

[0117] It can be understood that the assembly compatibility includes interface matching (whether the interface types, sizes, positions, etc. of the adapted prefabricated components match), reasonable space layout (no conflict in space during installation, with sufficient operation and maintenance space), and functional coordination (for example, in the prefabricated unit of the ventilation system, check whether the air volume and air pressure of the fan component and the air duct component match to ensure the normal operation of the ventilation system).

[0118] It can be understood that if the assembly compatibility of each prefabricated component meets the assembly standard, a corresponding prefabricated component information library is generated based on each prefabricated component, including the name, model, specification, material, bearing capacity, load information, manufacturer, assembly requirements (including assembly position, sequence, connection method, fittings), topological association relationship, etc. of the prefabricated component.

[0119] In the present invention, by decomposing the integrated support and hanger path into a number of prefabricated units, the refinement and standardization of the construction tasks are realized. Each prefabricated unit can be prefabricated and produced in the factory, reducing the on-site construction time and workload. The prefabricated units are produced in the factory with a stable production environment and more strict quality control. Compared with on-site construction, the factory can adopt more advanced production equipment and processes to ensure the accuracy and quality of the prefabricated components. Verifying the assembly compatibility before the production of the prefabricated units can detect possible assembly problems between the prefabricated components in advance. Through the advance verification, it can ensure the smooth assembly of the prefabricated components on-site and improve the construction efficiency.

[0120] Step S6: Determine the construction priority of each prefabricated component in the integrated support and hanger based on the prefabricated component information library and the building structure information to improve the construction accuracy.

[0121] Please refer to Figure 4As shown, it is a schematic flowchart for determining the construction plan of the comprehensive support hanger in the embodiment of the present invention; specifically, in step S6, determining the construction priorities of each prefabricated component in the comprehensive support hanger includes:

[0122] Step S61, determining the topological dependency relationship of each prefabricated component based on the prefabricated component information library and the building structure information;

[0123] In implementation, obtain the detailed information of each prefabricated component from the prefabricated component information library, clarify the building structure information, including the positions, dimensions, load-bearing capacities, etc. of beams, columns, and walls, as well as the layout of the building space and the division of each functional area. Define each prefabricated component as a node. For example, a support hanger and a pipe clamp are each regarded as an independent node. Determine the edges according to the connection relationship or assembly sequence between the components. Use professional graphic drawing software or topological analysis tools to visually represent the nodes and edges to form a topological graph of the prefabricated components. Analyze the dependency relationship of each component based on the building structure and construction technology, so as to establish the topological dependency relationship of each prefabricated component.

[0124] Step S62, constructing a priority scoring model based on the topological dependency relationship of each prefabricated component and the construction complexity of each prefabricated component;

[0125] Specifically, step S62 includes:

[0126] Step S621, constructing a construction complexity evaluation model based on the prefabricated component information library and the building structure information;

[0127] Step S622, determining the construction complexity of each prefabricated component based on the construction complexity evaluation model;

[0128] Step S623, constructing a priority scoring model based on the topological dependency relationship of each prefabricated component and the construction complexity of each prefabricated component.

[0129] Step S63, determining the construction priorities of each prefabricated component in the comprehensive support hanger based on the prefabricated component information library and the priority scoring model.

[0130] In implementation, actual implementers can train a machine learning model based on prefabricated component information that has passed the eligibility test in historical data and the corresponding building structure information to obtain a construction complexity assessment model for comprehensively evaluating the complexity of prefabricated components themselves, installation environment complexity, and connection and assembly complexity. Alternatively, determine evaluation indicators based on the complexity of prefabricated components themselves, installation environment complexity, and connection and assembly complexity. Complexity of prefabricated components themselves: Obtain the geometric complexity of the component (such as whether it is an irregular structure), size (larger components are more difficult to construct), and material characteristics (special materials may require special construction techniques) from the prefabricated component information library. For example, compared with conventional rectangular pipe supports and hangers, irregularly shaped pipe supports and hangers have higher construction complexity; super-large components have increased complexity due to transportation and installation difficulties; components made of new alloy materials have increased complexity because construction workers are not familiar with welding and other techniques. Installation environment complexity: Based on the building structure information, consider the spatial limitations of the installation location (such as narrow pipe shafts, equipment-intensive areas), height (working at heights increases construction difficulty), and proximity to other structures or equipment (construction needs to be avoided or coordinated). In the core tube area of a building, the space is narrow and there are many types of pipelines, so the installation environment complexity of prefabricated components here is very high; while in an open basement space, the installation environment is relatively simple. Connection and assembly complexity: Refer to the assembly information in the prefabricated component information library and analyze the difficulty of the connection method between components (such as the complexity of welding, bolt connection, and riveting is different), and the number of connection points (more connection points mean longer construction time and more prone to errors). For example, the on-site welding connection method is more complex than bolt connection, requires professional welders, and has a greater difficulty in controlling welding quality; complex pipe support and hanger systems with numerous connection points require more labor and time to ensure accurate connection. Use methods such as the Analytic Hierarchy Process (AHP) to assign index weights to the importance of each evaluation indicator based on an expert system, and thus construct a construction complexity assessment model. For example, the score for the complexity of components themselves is C1, the score for the installation environment complexity is C2, the score for the connection and assembly complexity is C3, and the comprehensive score for construction complexity is S. Then S = a×C1 + b×C2 + d×C3. (Each score can be scored according to a pre-established scoring standard, such as dividing each indicator into levels 1 to 5, with level 1 being the lowest complexity and level 5 being the highest complexity). a is the index weight corresponding to the complexity of components themselves, b is the index weight corresponding to the installation environment complexity, and d is the index weight corresponding to the connection and assembly complexity.

[0131] It can be understood that the actual implementers can train the neural network model based on the topological dependencies of the prefabricated components in the historical data and the construction complexity of each prefabricated component to construct a priority scoring model. Sort all the prefabricated components according to the priority score, and determine the construction sequence from high to low. The components with high scores are arranged first. Combining the assembly information and building structure information in the prefabricated component information library, a detailed construction plan is formulated according to the priority order.

[0132] By determining the topological dependencies of each prefabricated component, the present invention can clearly understand the sequence of each component during the construction process. Constructing a priority scoring model based on the topological dependencies of each prefabricated component and the construction complexity of each prefabricated component helps to formulate a more scientific construction plan for the comprehensive support and hanger. According to the priority score, the components with high priority are arranged in the early stage of construction or on the critical path and constructed first, which can ensure that the critical path of the entire construction project is not delayed and improve the construction efficiency.

[0133] The present invention constructs a BIM comprehensive support and hanger model by integrating pipeline construction information and building structure information, which can intuitively present the spatial relationship between the comprehensive support and hanger, pipelines, and building structures. By modular processing, the complex BIM comprehensive support and hanger model is decomposed into several independent modules, and determining the key module features can reduce the amount of data processing and improve the data processing efficiency. By generating a dynamic collision rule set based on the key module features, it can adapt to different project requirements, improve the accuracy and comprehensiveness of collision detection, avoid conflicts between the comprehensive support and hanger and the building structure and pipelines during construction, and ensure the construction quality and efficiency. By accurately positioning the collision abnormal nodes and determining the comprehensive support and hanger path in combination with the connection constraint conditions, an effective solution is provided to solve the collision problem, avoid randomly adjusting the position of the support and hanger and affecting the overall structural stability and pipeline function, and improve the construction efficiency and quality. Adjust the pipeline construction information according to the comprehensive support and hanger path to generate a prefabricated component information library, realize the optimization of construction information. The prefabricated component information library contains the prefabricated component structure and assembly method, provides detailed guidance for prefabrication, improves the production efficiency and quality of prefabricated parts, reduces the on-site processing workload, and improves the construction efficiency. Determine the construction priority of each prefabricated component according to the prefabricated component information library and building structure information, reasonably arrange the construction sequence, avoid construction chaos, and improve the construction efficiency and accuracy.
