Description

Technical Field

[0001] The present invention relates to the technical field of electrical construction, and in particular to a BIM-based air-conditioning system installation construction method. Background Art

[0002] In recent years, with the increasing requirements for clean environment in the fields of industry and scientific research, dust-free environment air conditioning systems have been widely used as key technologies in fields with high cleanliness requirements such as semiconductor manufacturing and biopharmaceuticals. This type of air conditioning system needs to ensure the cleanliness of the environment during installation and construction, while meeting the technical requirements of high precision and high reliability. At present, the installation and construction of dust-free environment air conditioning systems mainly adopt the following technical methods: First, manual measurement and drawing, which allows the construction personnel to obtain dimensional data through on-site measurement, and the designers manually draw construction drawings based on these data. This method relies heavily on the experience of workers. Secondly, traditional CAD software assisted design, CAD software is widely used in the drawing of construction drawings, which can improve the design accuracy to a certain extent, but it only provides two-dimensional plane design functions. Finally, the initial integrated BIM technology application, some existing engineering projects have begun to introduce building information modeling (BIM) technology in the design stage to create three-dimensional digital models to optimize the design effect. Although these technical means have improved the design and construction level of dust-free environment air conditioning systems to a certain extent, there are still significant deficiencies in the accuracy, efficiency and collaboration of installation and construction, and it is difficult to fully meet the needs of high-standard dust-free environments.

[0003] However, in the existing technology, manual measurement, CAD design, and the initial application of BIM technology cannot be dynamically adjusted during the construction phase, resulting in the design model not being consistent with the actual construction situation and large construction errors. Traditional construction methods rely heavily on manual operation and experience, and measurement errors and installation deviations occur from time to time, making it difficult to meet the strict requirements of dust-free environments for high-precision construction. In addition, due to the disconnection between design and actual construction, the operating performance of the air-conditioning system after installation is often unstable, affecting the cleanliness of the environment and the overall reliability of the system.

[0004] Secondly, during the construction process, existing methods such as manual measurement and rework adjustments are time-consuming and inefficient, which directly prolongs the construction period. Frequent rework is required when the design plan does not match the construction site, resulting in material waste and increased labor costs. In addition, there is a lack of effective construction progress management tools, the construction process is not smooth, the resource allocation efficiency is low, and the construction period delay is common. These problems directly lead to an increase in the construction cost of the dust-free environment air conditioning system and limit the effectiveness of the project.

[0005] Furthermore, in the current construction methods, the information between the design, construction and supervision teams is highly isolated, lacking a unified real-time sharing mechanism, resulting in low collaboration efficiency, which can easily lead to information misunderstandings and construction deviations. Quality supervision mainly relies on manual inspections, which are backward and difficult to detect problems in a timely manner, and cannot meet the needs of efficient quality control. These problems result in the final system results often failing to fully meet customers' high expectations for a dust-free environment, affecting the overall quality of the project and customer satisfaction.

[0006] Finally, the existing construction technology lacks virtualization support, and construction workers cannot rehearse operations in a virtual environment, which makes it difficult to identify and avoid risks in a timely manner during the construction process, and there is a lot of rework. In addition, the application of BIM technology is limited to the design stage, and it fails to effectively run through the entire construction process, and the integration with intelligent technology is low. Traditional construction methods rely more on manual experience, lack of intelligence, and are difficult to adapt to the complexity and high requirements of dust-free environment construction, further limiting the industry's intelligent development space. Summary of the invention

[0025] Specifically, in step S1, the three-dimensional digital model of the dust-free environment air-conditioning system is established on the BIM platform, which is the basic step of this method; the construction information is collected and sorted through the BIM platform, including the specific data of the building design, structural layout and mechanical and electrical pipelines; the professional software Revit and Navisworks are used to combine the spatial distribution inside the actual building and the direction of various pipeline lines to build an accurate three-dimensional digital model; this modeling process can clearly present the positional relationship of each component and provide an intuitive reference basis for subsequent construction; at the same time, the BIM platform supports multi-party collaboration and data sharing, and can update and optimize the model in real time, improve the matching degree between the design and the actual construction, and reduce the risk of rework caused by inaccurate design; this modeling method ensures the efficiency and accuracy of the construction preparation stage, and lays a solid foundation for subsequent steps; In step S2, installing and debugging the data acquisition device is an important part of dynamically monitoring the construction environment. The data acquisition device mainly uses high-precision temperature and humidity sensing equipment to monitor the temperature and humidity parameters of the construction site in real time. These devices are connected to the BIM platform to dynamically feed back the collected environmental data to the three-dimensional digital model, thereby updating the model content in real time, so that each step of the construction process can be adjusted according to the current environmental conditions. This process not only ensures the accuracy of environmental data, but also makes the construction plan more flexible and adaptable. Through dynamic data updates, construction personnel can quickly determine whether the current construction conditions meet the dust-free environment standards, thereby effectively avoiding construction problems caused by environmental parameter deviations. In step S3, start Starting the intelligent construction management system and importing BIM models and related parameter settings are important steps to achieve intelligent management; the intelligent construction management system comprehensively controls all aspects of the project through interaction with multiple subsystems; its functions include project management, progress tracking and bill of materials generation, and can monitor construction progress and material usage in real time; through the open API interface, the intelligent construction management system and the BIM platform achieve seamless data interaction, and model data updates, construction progress feedback and environmental parameter synchronization can all be completed in real time in the system; this intelligent management method significantly improves construction efficiency, reduces the need for manual intervention, and ensures a high degree of consistency in information during the construction process, providing strong support for precise construction; In step S4, according to the construction guidance document generated by the intelligent construction management system, the construction personnel first perform simulation operations on the virtual reality and augmented reality (VR / AR) platform; the construction guidance document contains the installation location of the components, environmental conditions, equipment operating status, quality inspection standards, construction steps and operation instructions, safety protection measures, schedule and bill of materials information; these details provide a comprehensive reference for the construction personnel; on the VR / AR platform, the construction personnel can conduct virtual operation drills in advance, identify possible construction risks and optimize the construction process; after confirmation, the construction personnel will carry out actual construction operations according to the guidance document; this task instruction execution method reduces the rework caused by problems found in the actual construction, and improves the accuracy of the construction through simulation verification; In step S5, regular inspection and maintenance of data acquisition devices and other hardware facilities are key links to ensure the continuity and accuracy of the construction process. During the construction process, since the data acquisition devices are exposed to the construction environment for a long time, their performance may be affected by external factors, so they need to be calibrated and functionally inspected regularly. At the same time, necessary spare components are prepared for quick replacement to ensure the normal operation of the monitoring equipment. This maintenance work enables the construction environment data to be continuously and stably fed back to the BIM platform, ensuring that each step of the construction process meets the requirements of a dust-free environment. In addition, this real-time maintenance mechanism greatly reduces the risk of construction interruption due to equipment failure, and improves construction efficiency and project quality. In step S6, implementing comprehensive safety protection measures during the construction process is an important guarantee for ensuring the safety of construction workers and the smooth progress of the project; construction workers are required to wear personal protective equipment such as safety helmets, protective gloves, protective glasses, dust masks, protective clothing and non-slip shoes; dust is removed through an air shower before construction to ensure that the dust-free environment standard is not damaged; the construction area is separated from other areas by isolation barriers to prevent unauthorized entry, and warning signs are set up in the area to indicate potential risks; in addition, the temperature, humidity and air quality parameters of the construction area are monitored in real time by environmental monitoring equipment to ensure that the construction conditions meet the standards; for power safety, it is required to turn off the power before construction and install a leakage protection device to avoid electrical accidents; workers working at heights are equipped with safety belts and protective nets to prevent falling; emergency drills are organized regularly during the construction process to familiarize construction workers with the emergency handling process; and a series of safety protection measures are taken to minimize safety hazards during construction.

[0026] Example 2: Installation and construction method of dust-free environment air conditioning system based on CAD design step: S1. CAD design: Use CAD software to design two-dimensional plane construction drawings, mainly relying on manual data input and manual verification; S2. On-site measurement and recording: Construction personnel conduct on-site measurements, record the data on paper, and manually input them into the CAD drawing; S3. Construction operation: Install according to the design drawings and manually calibrate the installation position; S4. Manual inspection and adjustment: Perform quality inspection based on the actual installation results and make manual adjustments if any problems are found; S5. Equipment maintenance: Regular manual inspection after equipment commissioning is completed, without using data acquisition devices and intelligent management systems.

[0027] Summarize: In this embodiment, the construction drawings are only two-dimensional, and the design is often inconsistent with the actual situation, which makes adjustments difficult, resulting in a lot of rework and a long construction period. The lack of dynamic adjustment and accurate monitoring makes the stability of the construction system poor.

[0028] Example 3: Installation and construction method of dust-free environment air conditioning system based on on-site manual measurement step: S1. Manual measurement: Construction personnel directly measure manually on site and record data section by section; S2. Component installation and adjustment: Manually install components according to the measurement data, and repeatedly debug during the process; S3. Manual data recording: During the installation process, the construction personnel manually recorded the data for reference; S4. Progress management: Using manual methods to track construction progress and lacking accurate project management tools; S5. Inspection and maintenance: After the construction is completed, regular manual inspection and maintenance are carried out.

[0029] Summarize: Due to reliance on manual measurement and recording, construction accuracy is difficult to ensure, data accuracy is low, and adjustments are cumbersome. The lack of information support and precise project management tools leads to low construction efficiency and extended construction periods.

[0030] Example 4: Traditional single-department collaboration dust-free environment air conditioning system installation and construction method step: S1. Separate design by department: The design department completes the drawing design, and the construction department only constructs according to the plan; S2. On-site manual measurement and construction: Construction personnel manually measure on-site and install step by step according to the two-dimensional design drawings; S3. Manual communication between departments: The design department and the construction department use manual communication to provide feedback on issues, but the information is not timely; S4. Quality supervision: Quality supervision needs to manually check the construction quality and lacks real-time progress feedback; S5. Regular equipment maintenance: After the equipment is installed, construction personnel will conduct regular manual inspection and maintenance.

[0031] Summarize: Due to poor communication between departments, data cannot be shared, and information asymmetry, construction deviations are easily caused. The quality supervision process is cumbersome and lacks real-time monitoring, which affects the quality of the project and the progress of the project.

[0032] Example 5: Installation and construction method of dust-free environment air conditioning system with limited BIM technology application step: S1. BIM preliminary modeling: Use BIM software to create a three-dimensional model during the design phase. This is limited to the initial design and should not be used in the construction process. S2. Generation of 2D construction drawings: Generate 2D construction drawings from BIM models for construction use; S3. On-site construction adjustment: If the design does not match the actual situation during construction, the on-site personnel will make manual adjustments; S4. Manual construction management: Construction progress relies on manual tracking and recording, lacking automated management; S5. On-site manual maintenance: After the equipment is installed, on-site personnel are required to perform manual inspection and maintenance.

[0033] Summarize: Although BIM technology was applied, it was limited to the design stage and not throughout the entire construction process, resulting in a disconnect between the model and actual construction data. Information could not be updated dynamically, and a complete construction management process could not be formed, resulting in low project controllability and reference value.

[0034] Summary: These five embodiments demonstrate the differences between different technical solutions, further highlighting the advantages of the present invention: Accuracy and reliability: In the second, third and fourth embodiments, there is a phenomenon that the design is inconsistent with the construction, and it is difficult to ensure the accuracy of the construction. The present invention achieves a high degree of matching between the construction plan and the actual situation through real-time data interaction between the BIM platform and the data acquisition equipment, ensuring the accuracy and stability of the construction.

[0035] Project cycle and cost: The manual measurement and data recording in the second and third embodiments prolong the project cycle and consume a lot of manpower and material resources. The present invention uses an intelligent construction management system to achieve automatic data tracking and progress management, greatly shortening the construction cycle and reducing project costs.

[0036] Multi-party collaboration and quality supervision: The single-department collaboration model of Example 4 has information asymmetry and is difficult to meet the needs of project quality supervision. The present invention enhances collaboration among all parties and improves quality management efficiency through data sharing and real-time updating of the intelligent construction management system.

[0037] Industry promotion and technical reference: The preliminary BIM technology application in Example 5 has not formed a complete construction process and lacks reference technical methods. The present invention integrates BIM technology throughout the entire design and construction process, forming a complete technical system, providing a reference case for similar projects in the future, and has promotion value.

[0038] In general, Example 1 of the present invention demonstrates significant technological progress, not only having significant advantages in accuracy, efficiency and cost control, but also having important innovation and application value in multi-party collaboration and industry promotion.

[0043] In terms of construction period, the first embodiment uses the intelligent construction management system to accelerate the construction progress, which only takes 50 hours; the second and third embodiments take the most time due to manual measurement and adjustment.
