[0003] 1. There is a certain probability of design defects and loopholes in the engineering drawings of pipeline construction, which cannot be found in time, resulting in rework in subsequent pipeline construction and directly increasing the construction cost.

[0004] 2. The engineering drawings of pipeline construction are based on the engineering drawings of civil structure, but due to manual operation, technical conditions and other factors, there are many inconsistencies between the actual civil structure and the drawings of civil structure, which will directly affect the subsequent pipeline construction.

[0005] Therefore, the present application is proposed. SUMMARY

[0006] In view of the problem that the actual working condition is different from the working condition corresponding to the drawings in the pipeline construction process in the prior art, the present application provides a method for mechanical and electrical pipeline installation based on BIM+three-dimensional laser, which combines BIM technology and three-dimensional scanning technology to ensure the efficiency of model establishment, simulate the pipeline construction process based on the actual civil structure construction process, determine the influence of the actual civil structure on pipeline installation, and adjust according to the actual civil structure, greatly improving the engineering efficiency and reducing the problem of resource waste due to rework.

[0007] To achieve the above-mentioned application purposes, the present application provides the following technical solutions:

[0008] The present application relates to a method for mechanical and electrical pipeline installation based on BIM+three-dimensional laser, comprising the following steps:

[0009] Building a BIM model based on the construction drawings of civil structure;

[0010] Using a three-dimensional laser scanner to perform three-dimensional laser measurement on the civil structure to obtain calibration parameters of the civil structure;

[0011] The BIM model is optimized by combining the collected calibration parameters to obtain an optimized model of the civil structure;

[0012] Based on the optimization model and pipeline construction drawings, pipeline construction simulation is performed, and the pipeline construction drawings are optimized based on the simulation results.

[0013] The installation of electromechanical pipelines is assisted by the optimized pipeline construction drawings.

[0014] In this scheme, a BIM model is first constructed based on the original civil engineering construction drawings to form the building's civil engineering structure BIM. Then, a 3D laser scanner is used to scan the civil engineering structure to obtain its calibration parameters. Based on these calibration parameters and the BIM model constructed from the original civil engineering construction drawings, the model is optimized to match the actual condition of the completed civil engineering structure. Furthermore, based on the original pipeline installation drawings, pipeline installation simulation is performed in the optimized BIM model to simulate the installation process and its effects. Based on the installation process and effects, the pipeline installation drawings are further optimized to form an optimized version. The system provides pipeline construction drawings and facilitates pipeline construction based on these drawings, thereby aiding in the installation of electromechanical pipelines. The auxiliary installation scheme provided in this plan utilizes a BIM model built based on the original civil structure model. Optimization of the actual building's civil structure model effectively reduces the data processing volume during BIM model component assembly, significantly improving model construction efficiency. Furthermore, simulation of the optimized model directly simulates the pipeline construction process based on the actual civil structure construction, thus determining the impact of the actual civil structure on pipeline installation. Adjustments can be made according to the actual situation, greatly improving project efficiency and reducing resource waste due to rework.

[0015] Furthermore, the calibration parameters include floor spacing, floor slab parallelism, and floor slab inclination.

[0016] Furthermore, based on the optimized model and pipeline construction drawings, a pipeline construction simulation is performed, specifically including the following steps:

[0017] Based on the type of pre-built pipeline, pipeline priority is classified;

[0018] Based on pipeline priority, a pipeline construction simulation is performed, and pipeline collision detection is carried out during the construction process;

[0020] Furthermore, pipeline construction simulation is performed according to pipeline priority. During the construction process, pipeline collision detection is conducted, specifically including:

[0021] Based on the preset locations in the original pipeline construction drawings, a pipeline construction simulation with the highest priority is performed on the optimized model.

[0022] Complete the pipeline construction simulation for the first priority, then proceed to the pipeline construction simulation for the second priority. After the construction is completed, perform collision detection.

[0023] After collision detection, a simulation of building a third-priority pipeline is performed.

[0024] Repeat the above construction and testing steps to complete the overall pipeline construction.

[0025] Furthermore, it also includes a pipeline space verification step, which, after all pipeline construction simulations are completed, specifically includes the following steps:

[0026] The location of the marked pipeline is determined, and the distance from the marked pipeline to the top surface of the floor is obtained, wherein the marked pipeline is the pipeline with the farthest distance from the top surface of the floor among all pipelines;

[0027] Determine the radius of the marked pipeline and obtain the maximum height of the overall pipeline construction model;

[0028] The maximum height obtained is compared with the maximum height in the preset pipeline construction drawings, and it is determined whether the optimized pipeline construction position will affect the floor height. If the maximum height obtained is less than or equal to the preset maximum height, the optimized pipeline construction drawings are exported; if the maximum height obtained is greater than the preset maximum height, the model is adjusted.

[0029] Furthermore, the model adjustment specifically includes the following steps:

[0030] Adjust the position of the marked pipeline so that the maximum height of the overall pipeline model corresponding to the marked pipeline is less than or equal to the preset maximum height;

[0031] Adjust the positions of the remaining pipelines according to the positions of the marked pipelines.

[0032] Furthermore, the position adjustment specifically includes the following steps:

[0033] Determine the priority of marked pipelines;

[0034] Pipelines with higher priority than the marked pipelines are adjusted in reverse order of priority.

[0035] Pipelines with priorities lower than the marked pipelines are adjusted in ascending order of priority.

[0036] Determine the distance between the farthest end of the adjusted pipeline model and the floor slab, and determine its relationship with the maximum height in the preset pipeline construction drawings; if it is less than or equal to the preset maximum height, export the optimized pipeline construction drawings; if the obtained maximum height is greater than the preset maximum height, repeat the model adjustment steps.

[0037] Furthermore, during the pipeline construction simulation, the installation position of each pipeline is adjusted to obtain the installation range of each pipeline, wherein the installation range is determined based on collision detection.

[0038] Furthermore, the installation of electromechanical pipelines is assisted by the optimized pipeline construction drawings, specifically including the following steps.

[0039] Based on the optimized pipeline construction drawings, and according to the priority of the pipelines, the pipelines are constructed in sequence.

[0040] The location of the pipelines was confirmed using a 3D laser scanner, and it was also confirmed that the pipelines under construction were within the corresponding installation range.

[0041] Furthermore, during the pipeline installation process, the location of the pipeline is confirmed using a 3D laser scanner, and collision checks are performed in the corresponding simulation results.

[0042] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0043] This invention relates to a method for installing electromechanical pipelines based on BIM and 3D laser-assisted installation. First, a BIM model is constructed based on the original civil engineering construction drawings, forming a BIM of the building's civil engineering structure. Then, a 3D laser scanner is used to scan the civil engineering structure to obtain its calibration parameters. Based on these calibration parameters and the BIM model constructed from the original civil engineering construction drawings, the model is optimized to match the actual condition of the completed civil engineering structure. Furthermore, based on the original pipeline installation drawings, pipeline installation is simulated in the optimized BIM model, simulating the installation process and its effects. Based on the installation process and effects, the pipeline installation is then... The construction drawings are optimized to form optimized pipeline construction drawings, and pipelines are constructed based on these drawings, thereby assisting in the installation of electromechanical pipelines. The auxiliary installation scheme provided in this plan uses a BIM model built based on the original civil structure model. Optimizing the civil structure model based on the actual building effectively reduces the data processing volume of the BIM model component process, greatly improving model construction efficiency. Furthermore, by simulating the optimized model, the pipeline construction process during the actual civil structure construction can be directly simulated, thus determining the impact of the actual civil structure on pipeline installation and allowing for adjustments based on actual conditions. This significantly improves project efficiency and reduces resource waste caused by rework. Attached Figure Description

[0052] Example

[0053] like Figure 1 As shown, this embodiment of the invention relates to a method for installing electromechanical pipelines based on BIM and 3D laser-assisted installation, comprising the following steps:

[0054] Building BIM model based on construction drawings of civil engineering structure;

[0055] A 3D laser scanner is used to perform 3D laser measurement on the civil engineering structure to obtain the calibration parameters of the civil engineering structure.

[0056] The BIM model is optimized by combining the collected calibration parameters to obtain an optimized model of the civil structure;

[0057] Based on the optimization model and pipeline construction drawings, pipeline construction simulation is performed, and the pipeline construction drawings are optimized based on the simulation results.

[0058] The installation of electromechanical pipelines is assisted by the optimized pipeline construction drawings.

[0059] As those skilled in the art should know, in engineering construction, construction is usually carried out based on corresponding engineering drawings. Conventional engineering drawings are two-dimensional drawings. Construction workers build corresponding three-dimensional building structures based on two-dimensional drawings. However, in the construction process, there are certain engineering errors under the premise of meeting the structural strength of the building. It is precisely because of the occurrence of engineering errors that they will directly affect the subsequent pipeline installation.

[0060] In this scheme, a BIM model is first constructed based on the original civil engineering construction drawings to form the building's civil engineering structure BIM. Then, a 3D laser scanner is used to scan the civil engineering structure to obtain its calibration parameters. Based on these calibration parameters and the BIM model constructed from the original civil engineering construction drawings, the model is optimized to match the actual condition of the completed civil engineering structure. Furthermore, based on the original pipeline installation drawings, pipeline installation simulation is performed in the optimized BIM model to simulate the installation process and its effects. Based on the installation process and effects, the pipeline installation drawings are further optimized to form an optimized version. The system provides pipeline construction drawings and facilitates pipeline construction based on these drawings, thereby aiding in the installation of electromechanical pipelines. The auxiliary installation scheme provided in this plan utilizes a BIM model built based on the original civil structure model. Optimization of the actual building's civil structure model effectively reduces the data processing volume during BIM model component assembly, significantly improving model construction efficiency. Furthermore, simulation of the optimized model directly simulates the pipeline construction process based on the actual civil structure construction, thus determining the impact of the actual civil structure on pipeline installation. Adjustments can be made according to the actual situation, greatly improving project efficiency and reducing resource waste due to rework.

[0061] In some embodiments, the calibration parameters include floor spacing, floor slab parallelism, and floor slab inclination.

[0062] It should be noted that the main purpose of collecting calibration parameters is to adjust the original BIM model so that it corresponds to the actual civil engineering structure. It should be noted that those skilled in the art should know that the model of the actual civil engineering structure can be directly constructed by using 3D laser scanning to obtain point cloud data. However, in this solution, by pre-constructing the original BIM model and then adjusting the model, the amount of computer processing and processing time are greatly reduced, and the model construction efficiency is improved.

[0063] Furthermore, as those skilled in the art should know, during the design process of civil engineering structures, three-dimensional structural simulations are usually performed, and corresponding construction drawings are generated after multiple adjustments. In this solution, the pre-built structural model can be directly used and converted into the corresponding BIM model, thereby saving production costs and improving production efficiency.

[0064] In some embodiments, pipeline construction simulation is performed based on the optimization model and pipeline construction drawings, specifically including the following steps:

[0065] Based on the type of pre-built pipeline, pipeline priority is classified;

[0066] Based on pipeline priority, a pipeline construction simulation is performed, and pipeline collision detection is carried out during the construction process;

[0067] Based on the simulation results of pipeline construction, optimized pipeline construction drawings are generated.

[0068] Among them, electromechanical pipelines include, but are not limited to, heating and ventilation ducts, smoke exhaust ducts, power and weak current cable trays, water supply and drainage pipes, fire sprinkler pipes, air conditioning water pipes, etc. As those skilled in the art should know, when constructing the corresponding electromechanical pipelines, they are usually constructed in a certain order. Specifically, the construction order of the corresponding pipelines is the priority of the corresponding pipelines, and the first one constructed has the highest priority.

[0069] like Figure 2 As shown, in some embodiments, pipeline construction simulation is performed according to pipeline priority. During the construction process, pipeline collision detection is performed, specifically including:

[0070] Based on the preset locations in the original pipeline construction drawings, a pipeline construction simulation with the highest priority is performed on the optimized model.

[0071] Complete the pipeline construction simulation for the first priority, then proceed to the pipeline construction simulation for the second priority. After the construction is completed, perform collision detection.

[0072] After collision detection, a simulation of building a third-priority pipeline is performed.

[0073] Repeat the above construction and testing steps to complete the overall pipeline construction.

[0074] The process involves simulating pipeline construction according to pipeline priority and conducting collision checks between pipelines during the construction process to determine whether the pipeline installation location meets the requirements. It should be noted that during the pipeline collision check, it is necessary to determine whether the newly constructed pipeline is in conflict with all existing pipelines.

[0075] During collision checks, if adjustments to existing pipelines are required, a new collision check must be performed on the adjusted pipelines.

[0076] In some embodiments, a pipeline space verification step is further included, wherein the pipeline space verification step is performed after all pipeline construction simulations are completed, and specifically includes the following steps:

[0077] The location of the marked pipeline is determined, and the distance from the marked pipeline to the top surface of the floor is obtained, wherein the marked pipeline is the pipeline with the farthest distance from the top surface of the floor among all pipelines;

[0078] Determine the radius of the marked pipeline and obtain the maximum height of the overall pipeline construction model;

[0079] The maximum height obtained is compared with the maximum height in the preset pipeline construction drawings, and it is determined whether the optimized pipeline construction position will affect the floor height. If the maximum height obtained is less than or equal to the preset maximum height, the optimized pipeline construction drawings are exported; if the maximum height obtained is greater than the preset maximum height, the model is adjusted.

[0080] It should be noted that verifying the size of the space can reduce the impact of pipeline installation on the floor height and avoid affecting the usable space due to adjustments to the pipeline structure.

[0081] The distance from the marked pipeline to the top surface of the floor refers to the distance from the axis of the marked pipeline to the top surface of the floor.

[0082] The location of the marked pipeline is the pipeline closest to the floor level in the entire pipeline system. By obtaining the height and the radius of the marked pipeline, the closest position of the entire pipeline structure to the ground is determined, thereby determining the range of the installation space of the entire pipeline structure. By comparison, it is determined whether there is any impact.

[0083] In some embodiments, the model adjustment specifically includes the following steps:

[0084] Adjust the position of the marked pipeline so that the maximum height of the overall pipeline model corresponding to the marked pipeline is less than or equal to the preset maximum height;

[0085] Adjust the positions of the remaining pipelines according to the positions of the marked pipelines.

[0086] Furthermore, the position adjustment specifically includes the following steps:

[0087] Determine the priority of marked pipelines;

[0088] Pipelines with higher priority than the marked pipelines are adjusted in reverse order of priority.

[0089] Pipelines with priorities lower than the marked pipelines are adjusted in ascending order of priority.

[0090] Determine the distance between the farthest end of the adjusted pipeline model and the floor slab, and determine its relationship with the maximum height in the preset pipeline construction drawings; if it is less than or equal to the preset maximum height, export the optimized pipeline construction drawings; if the obtained maximum height is greater than the preset maximum height, repeat the model adjustment steps.

[0091] Specifically, as those skilled in the art should know, after the marked pipelines are identified, the priority of the corresponding marked pipelines can be directly obtained, and the pipeline adjustment sequence can be divided according to the specific priority.

[0092] The specific adjustment order starts with the priority of the marked pipes. For pipes with higher priority than the marked pipes, the position of each pipe is adjusted in reverse order to meet the collision detection requirements. For pipes with lower priority than the marked pipes, the same adjustment is made. This will not be elaborated again.

[0093] In some embodiments, during pipeline construction simulation, the installation position of each pipeline is adjusted to obtain the installation range of each pipeline, wherein the installation range is determined based on collision detection.

[0094] As should be known to those skilled in the art, for pipelines, a rectangular coordinate system can be established on a plane perpendicular to the axis, with the axis of the marked pipeline or any pipeline as the origin. By determining the relative positional relationship between the pipelines, the range can be determined, where the range includes the range in the X-axis direction and the Y-axis direction in the corresponding rectangular coordinate system.

[0095] like Figure 3 As shown, in some embodiments, the installation of electromechanical pipelines is assisted by optimized pipeline construction drawings, specifically including the following steps:

[0096] Based on the optimized pipeline construction drawings, and according to the priority of the pipelines, the pipelines are constructed in sequence.

[0097] The location of the pipelines was confirmed using a 3D laser scanner, and it was also confirmed that the pipelines under construction were within the corresponding installation range.

[0098] Furthermore, during the pipeline installation process, the location of the pipeline is confirmed using a 3D laser scanner, and collision checks are performed in the corresponding simulation results.

[0099] In this solution, the location of the pipelines to be constructed is determined again by using a 3D laser scanner, which can further guide the installation process. Furthermore, collision checks can be performed by importing the optimized model. As should be known by those skilled in the art, after importing the corresponding pipeline parameters into the optimized model, simulations can also be performed based on the structural model to guide the construction process.

[0100] The above are preferred embodiments of the present invention. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on the present invention are within the protection scope of the present invention.
