Description

Technical Field

[0001] The present invention relates to the technical field of electromechanical equipment progress management, and in particular to a method for electromechanical equipment progress management based on BIM technology. Background Art

[0002] In the construction of mechanical and electrical engineering, the installation process of equipment and pipelines is complex and cross-operation is frequent. The traditional progress control method relies on two-dimensional drawings and experience judgment, which makes it difficult to track the progress of each link in real time. Problems such as poor process connection and unreasonable resource allocation are prone to occur, leading to construction delays. BIM technology can integrate equipment parameters, progress plans and other information by constructing three-dimensional models to achieve visual control, making it easier to detect progress deviations in advance and make timely adjustments. Therefore, it has become an important means to improve the efficiency of mechanical and electrical equipment progress control.

[0003] In the process of mechanical and electrical equipment progress control, the installation progress of mechanical and electrical equipment pipelines has a key impact. As the core carrier of equipment connection, the pipeline laying path and installation sequence are closely related to the equipment placement. Delays or deviations in pipeline installation will directly lead to the subsequent equipment being unable to connect as planned, thereby slowing down the overall progress.

[0004] During the design process, BIM software only calculates according to the model outer contour of the electromechanical equipment pipe body. The actual outer wall contour is affected by additional structures such as the insulation layer, connector protrusions, and instrument installation, resulting in the actual outer wall contour being inconsistent with the model contour. This makes some pipe bodies not show collision risks during design. However, in actual construction, due to the superposition of the real contours, it is very easy for pipes to be too close or even collide, which in turn causes the installation process to stagnate and rework, resulting in a deviation between the actual installation progress of the electromechanical equipment and the BIM management progress, affecting the overall construction efficiency. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a method for controlling the progress of electromechanical equipment based on BIM technology, which solves the problem that the existing BIM software only calculates according to the outer contour of the electromechanical equipment pipe body model during design, while the actual outer wall contour of the pipe body is different from the model contour due to additional structures such as the insulation layer, connector protrusions, and instrument installation. As a result, some pipe bodies have no collision risk when designed, but are prone to pipes being too close or colliding during actual construction, which in turn causes the installation process to stagnate and rework, resulting in a deviation between the actual installation progress of the electromechanical equipment and the BIM control progress.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A method for controlling the progress of electromechanical equipment based on BIM technology, comprising the following steps:

[0007] S1. Use 3D modeling software and BIM integration software to substitute multiple electromechanical equipment parameters to establish a basic electromechanical equipment BIM model.

[0009] S2. Allocate the progress work hours for electromechanical equipment and the progress work hours for electromechanical equipment pipelines based on the basic electromechanical equipment BIM model established in step S1;

[0010] S3. Based on the electromechanical equipment pipeline parameters collected in step S1, dynamic collision risk is quantified using the weight calculation formula of the analytic hierarchy process and the weighted comprehensive evaluation method to obtain a comprehensive calculated collision probability;

[0011] S4. Adjust the electromechanical equipment progress working hours and electromechanical equipment pipeline progress working hours set in step S2 according to the comprehensive calculated collision probability obtained in step S3;

[0012] S5. Re-enter the mechanical and electrical equipment progress working hours and mechanical and electrical equipment pipeline progress working hours adjusted in step S4 into the basic mechanical and electrical equipment BIM model in step S2, and generate the final parameterized mechanical and electrical equipment progress management BIM model to realize mechanical and electrical equipment progress control.

[0013] Preferably, in step S1, a basic electromechanical equipment BIM model is established by using 3D modeling software and BIM integration software to substitute multiple electromechanical equipment parameters, including:

Then, the 3D modeling software will generate a model based on the model and the length, width, and height dimensions of the electromechanical equipment.

[0015] Then add the electromechanical equipment piping family, set the diameter and material as type parameters, and explicitly set the pipe length parameters. Insert the insulation thickness, and then insert the number and size of connectors and instruments.

[0016] Finally, use BIM integration software to first import the model produced by the 3D modeling software, then associate the equipment and pipelines to form a complete basic model and check the accuracy of the connection.

[0017] Preferably, in step S1, the electromechanical equipment parameters include: electromechanical equipment model and electromechanical equipment size; the electromechanical equipment pipeline parameters include: electromechanical equipment pipeline diameter, electromechanical equipment pipeline length, electromechanical equipment pipeline material, electromechanical equipment pipeline insulation layer, electromechanical equipment pipeline connectors and electromechanical equipment pipeline instruments.

[0018] Preferably, in step S2, the allocation of the electromechanical equipment progress working hours and the electromechanical equipment pipeline progress working hours includes:

[0019] In the BIM integration software, process hours are associated with model attributes according to the electromechanical equipment model. For example, if the water pump model is ISG50-160, the corresponding installation process hours are 8 hours. Large equipment models require an additional 24 hours of transportation and hoisting hours, while small equipment models do not require additional hours.

[0020] The working hours for electromechanical equipment pipelines are set according to the diameter and length, including: DN300×100m pipeline, the corresponding installation process working hours are 50 hours.

[0021] Preferably, in step S3, the electromechanical equipment pipeline parameters include: electromechanical equipment pipeline material, electromechanical equipment pipeline insulation layer, electromechanical equipment pipeline connectors and electromechanical equipment pipeline instruments.

[0022] Preferably, in step S3, the weight calculation formula of the analytic hierarchy process is specifically:

[0023] According to the probability and severity of occurrence, the weight calculation formula of the hierarchical analysis method is used to allocate the weights of the electromechanical equipment pipeline material, electromechanical equipment pipeline insulation layer, electromechanical equipment pipeline connectors and electromechanical equipment pipeline instruments;

[0024]

[0025] in:

[0027] Preferably, in step S3, the weighted comprehensive evaluation method calculation formula is specifically:

[0028] Substitute the mechanical and electrical equipment pipeline parameters into the weighted comprehensive evaluation method calculation formula to comprehensively calculate the collision probability:

[0029]

[0030] in:

[0031] represents the comprehensive collision probability;

[0032] Represents the weight of the material of the electromechanical equipment pipeline;

[0033] Represents the contour deviation caused by the pipe material, that is, the dimensional change due to thermal expansion and contraction, which can be obtained through material measurement;

[0034] Represents the weight of the insulation layer of the mechanical and electrical equipment pipeline;

[0035] Represents the thickness of the insulation layer, directly taking the insulation layer parameter value recorded in S1;

[0036] Represents the weight of the mechanical and electrical equipment pipeline connector;

[0037] Represents the raised height of the connector, which is obtained by actual measurement of the model, including the raised height of the flange connector. The actual measurement of the model is specifically: measured using a measuring ruler based on the size of the connector of different models;

[0038] Represents the weight of electromechanical equipment, piping and instrumentation;

[0039] Represents the protruding size of the instrument, obtained through actual measurement of the model, including pressure gauges and flow meters;

[0040] The safety distance threshold between pipe bodies is 100-300mm according to the specification;

[0041] At the same time, considering that the interference of multiple parameters in different situations is different, dynamic adjustment is performed based on the weight distribution in the calculation formula of the weighted comprehensive evaluation method. The different situations include high temperature and high humidity environments and areas with a large number of precision detection instruments.

[0042] Preferably, in step S4, the progress working hours of electromechanical equipment and the progress working hours of electromechanical equipment pipelines are adjusted, specifically:

[0043] Depending on the value of the comprehensive calculated collision probability, the installation schedule and working hours adjustment plan for electromechanical equipment and pipelines will also be different, including:

[0044] When the comprehensive collision probability is ≤0.2, the collision probability is judged to be low risk, and the original mechanical and electrical equipment progress working hours remain unchanged; when 0.2<comprehensive collision probability ≤0.5, the collision probability is judged to be medium risk, and the original mechanical and electrical equipment progress working hours are appropriately increased; when the comprehensive collision probability is greater than 0.5, the collision probability is judged to be high risk, and the working hours are significantly increased based on the original mechanical and electrical equipment progress working hours;

[0045] The final mechanical and electrical equipment progress hours are then calculated using the risk-weighted adjustment formula, including:

[0046]

[0047] in:

[0048] Represents the adjusted progress working hours of electromechanical equipment;

[0049] Represents the initial progress hours allocated in step S2;

[0050] is the risk impact coefficient,

[0051] If the risk is judged to be low, the original mechanical and electrical equipment progress hours remain unchanged. At this time: =0,

[0052] If it is judged to be a medium risk, the working hours of the original mechanical and electrical equipment will be appropriately increased. At this time: =0.3,

[0053] If it is judged to be high risk, the working hours will be significantly increased based on the original progress working hours of electromechanical equipment. At this time: =0.8;

[0054] is the comprehensive collision probability obtained in step S3.

[0055] The present invention provides a method for controlling the progress of electromechanical equipment based on BIM technology. It has the following beneficial effects:

[0056] 1. This invention incorporates additional structural parameters such as the insulation layer, connectors, and instruments of electromechanical equipment pipelines when establishing the BIM model, and uses the hierarchical analysis method and weighted comprehensive evaluation method to quantify the collision risks caused by these parameters. This solves the problem of traditional BIM design that only calculates based on the outer contour of the pipe model while ignoring the differences in the actual outer wall contour. It can identify the pipeline collision risks that may occur in actual construction in advance, reducing the occurrence of installation process stagnation and rework.

[0057] 2. This invention makes targeted adjustments to the progress hours of electromechanical equipment and pipelines based on the dynamic collision risk quantification results. By linking the comprehensive collision probability with the risk level, the direction of work hour adjustments at different risk levels is clearly defined, ensuring that work hour adjustments are based on evidence and avoiding the blind increase or decrease of work hours.

[0058] 3. The present invention combines the risk-weighted adjustment method formula to calculate the final progress working hours, organically combining the initial working hours, risk impact coefficient and comprehensive collision probability, so that the adjusted working hours can not only reflect the impact of collision risk on construction, but also maintain the scientificity and accuracy of the calculation, effectively reducing the deviation between the actual installation progress of electromechanical equipment and the BIM control progress, and improving the rationality of progress control.
