Description

Technical Field

[0001] The present invention relates to the technical field of cold and heat source machine rooms, and in particular to a hoisting construction method for an assembled cold and heat source machine room based on BIM technology. Background Art

[0002] The cold and heat source room is the place where the air-conditioning system prepares cold and heat, and is the cold and heat supply end of the entire air-conditioning system.

[0003] The Chinese patent with the announcement number CN111306363A discloses a method and structure for hoisting construction of an assembled fire pump room based on BIM technology. The method mainly uses BIM technology to comprehensively arrange and accurately model the equipment and pipelines in the machine room, determine the installation position and elevation of the equipment pipelines, and divide the pipeline prefabrication processing sections; set the support and hanger form and installation position, and design an integrated hoisting support system; prefabricate the pipe sections and supports and hangers according to the BIM processing drawings; after the pipe sections and supports and hangers are processed, according to the BIM processing drawings and the markings of the pipe section brackets that have been made, the pipe modules are assembled at one time according to the hoisting sequence determined by the construction plan, and the pipe sections and supports and hangers are hoisted by the integrated hoisting support system. Although the above patent solves the problem of hoisting construction, the following problems still exist in actual operation:

[0004] 1. The lifting equipment and the computer room were not effectively simulated and integrated, resulting in a mismatch between the equipment and the computer room during construction.

[0005] 2. No effective equipment inspection was carried out on the hoisting equipment to be put into or entering the computer room, resulting in the failure of the hoisting construction in the computer room. Summary of the invention

[0006] The purpose of the present invention is to provide a method for hoisting construction of an assembled cold and heat source machine room based on BIM technology. By deepening the construction through the Revit model, it is possible to ensure the accurate matching of the target virtual equipment data with the construction data. By using the Revit model for collision detection, it is possible to more intuitively check whether there is a potential collision between the hoisting equipment and the construction unit's site building, thereby avoiding risks in advance and reducing on-site changes and delays. By deepening the construction through the Revit model, it is possible to clearly display the construction details and requirements, improve the understanding and execution efficiency of the construction personnel, review the deviation of civil construction through 3D laser scanning, and use the BIM model to adjust the coordinate system of the construction building data, so as to ensure the accuracy of the BIM model of the assembled machine room. The construction drawings generated by the BIM model can intuitively display the entire process of hoisting construction, improve the construction quality and efficiency, and solve the problems in the prior art.

[0025] Add attribute information to the three-dimensional model of each lifting equipment, where the attribute information includes material, specification, purpose, load-bearing capacity, and usage restrictions;

[0026] After the attribute information is added, the target virtual device data is obtained.

[0030] After the format adjustment is completed, the target virtual equipment data with the format adjustment is subjected to collision detection with the construction data through the Revit model. The collision detection is to detect whether there is a potential collision between the hoisting equipment and the site building of the construction unit;

[0040] When the secondary quality evaluation result shows that the color quality requirements are met, the construction deepening drawing is determined to meet the color filling quality requirements;

[0041] When the secondary quality evaluation result indicates that the color quality requirements are not met, it is determined that the construction deepening drawing does not meet the color filling quality requirements.

[0042] Preferably, when the first color filling evaluation parameter is lower than the preset first parameter threshold, the color saturation, brightness and color filling coverage are used to perform a secondary color filling quality evaluation on the construction deepening drawing to obtain a secondary quality evaluation result, including:

[0050] comparing the comprehensive evaluation parameter with a preset second parameter threshold;

[0051] When the comprehensive evaluation parameter is lower than the preset second parameter threshold, it is determined that the secondary quality evaluation result does not meet the color quality requirement.

[0052] Preferably, the data parameters in the target construction deepening data are retrieved in S4, and equipment prefabrication is performed according to the data parameters, and the prefabricated equipment is sampled, including:

[0055] If there is any inconsistency, adjust the parameters of the automation equipment and reprocess;

[0056] The equipment that has passed the random inspection will be marked as standard lifting equipment data.

[0057] Preferably, the implementation plan for using the BIM model to implement the construction data and standard lifting equipment data in S5 includes:

When the shape of the prefabricated pipeline is irregular, it is constructed using a combined support and hanger, wherein the combined support and hanger is a combined support and hanger between the main frames of the circulating pump group;

[0062] When the prefabricated pipes are in rows or densely packed, they are assembled and constructed on the ground using prefabricated supports and hangers;

[0063] Finally, a virtual construction model with complete standard lifting equipment data in the BIM model of the assembly room is obtained;

[0065] Carry out the hoisting construction of the cold and heat source room according to the generated construction drawings.

[0066] Preferably, in S6, according to the attributes of each lifting equipment, on-site management is performed when the equipment is lifted, including:

[0067] When the equipment in the generated construction drawings enters the construction site, acceptance management is carried out. Among them, acceptance management is to check the specifications, models and dimensions of the equipment entering the construction site. The equipment on-site acceptance should be jointly accepted by representatives of Party A, the supervision unit and the construction unit, and the equipment and material inspection procedures should be completed;

[0068] After the equipment is accepted, it is placed in a storage area for storage and environmental management is performed on the storage environment. Environmental management refers to storage management based on the properties of the equipment.

[0069] The reserved holes, valves and pipelines are inspected and accepted. The size, position and verticality of the reserved holes are inspected and accepted; the strength and tightness of the valves are inspected and accepted; the winding direction and tightness of the hemp on the pipeline are inspected and accepted;

[0070] The lifting construction can be carried out only after the acceptance management, environmental management, and acceptance of reserved holes, valves, and pipelines have been inspected and qualified.

[0071] Preferably, during the hoisting construction in S7, the equipment at the construction site is quality inspected, and the qualification rate of the hoisting construction of the cold and hot source machine room is evaluated according to the quality inspection result, including:

[0075] The pass rate of the cold and heat source room hoisting construction is evaluated based on the results of the pipeline quality inspection and circuit quality inspection.

[0076] Compared with the prior art, the present invention has the following beneficial effects:

[0077] 1.

BRIEF DESCRIPTION OF THE DRAWINGS

[0080] Figure 1It is a schematic diagram of the hoisting construction steps of the assembled cold and heat source room of the present invention. DETAILED DESCRIPTION

[0081] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0082] In order to solve the problem in the prior art that after the lifting equipment of the computer room is obtained, the lifting equipment and the computer room are not effectively simulated and integrated, resulting in the mismatch between the equipment and the computer room during construction, please refer to Figure 1 , this embodiment provides the following technical solutions:

[0083] The hoisting construction method of the assembled cold and hot source room based on BIM technology includes the following steps:

[0084] S1: Confirmation of hoisting equipment: Confirm the basic information of the hoisting equipment in the cold and hot source room, and uniquely code and label each hoisting equipment;

[0085] Among them, each lifting equipment can be clearly identified and tracked through unique coding numbers, which helps reduce confusion and errors and improve work efficiency;

[0086] S2: Equipment model construction: Each lifting equipment is virtually constructed through the BIM model, and the virtually constructed lifting equipment is marked as the target virtual equipment data;

[0087] Among them, the BIM model provides powerful visualization functions, so that the three-dimensional model of the lifting equipment can be intuitively displayed to all relevant personnel;

[0088] S3: Model construction and drawing: The target virtual equipment data needs to be deepened by using the Revit model. After the construction deepening, the construction deepening drawing of the target virtual equipment data is obtained and marked as the target construction deepening data;

[0089] Among them, construction deepening through Revit models can clearly display construction details and requirements, improving the understanding and execution efficiency of construction personnel;

[0090] S4: Draw a model to inspect prefabrication: retrieve the data parameters in the target construction deepening data, perform equipment prefabrication according to the data parameters, conduct random inspection on the prefabricated equipment, and mark the equipment that has passed the random inspection as standard lifting equipment data;

[0091] Among them, random inspection of prefabricated components can timely discover and correct components that do not meet the requirements, thereby ensuring that all prefabricated components shipped out of the factory meet the requirements in the target construction deepening data;

[0092] S5: On-site construction of hoisting equipment: Use the BIM model to compile an implementation plan based on the construction data and standard hoisting equipment data, and carry out hoisting construction according to the compiled plan;

[0093] Among them, through virtual construction and simulation analysis, potential safety hazards can be discovered and resolved in advance;

[0094] S6: Construction site management: According to the properties of each lifting equipment, on-site management is carried out when the equipment is being lifted, and lifting construction is carried out after the on-site management is qualified;

[0095] Among them, through strict acceptance management and environmental management, as well as acceptance inspection of reserved holes, valves and pipelines, it can ensure that the preparatory work before construction is sufficient and in place, reducing problems and delays during the construction process;

[0096] S7: Quality inspection of hoisting construction: During the hoisting construction, the equipment on the construction site will be inspected for quality, and the qualification rate of the hoisting construction of the cold and hot source room will be evaluated based on the quality inspection results;

[0097] Among them, quality inspection helps to ensure that every step in the construction process meets quality standards and safety requirements, thereby improving the quality of the entire lifting construction.

[0098] Confirm the basic information of the hoisting equipment in the cold and hot source room in S1, and uniquely code and label each hoisting equipment, including:

[0099] The hoisting equipment in the cold and hot source room includes water pumps, valve components, pipes, supports and hangers, chilled water pumps, hot water circulation pumps, cold water manifolds, cold water collectors and cooling water pumps;

[0100] The basic information of the hoisting equipment includes the model, installation size and quantity of water pumps, valve components, pipes, supports and hangers, chilled water pumps, hot water circulation pumps, cold water manifolds, cold water collectors and cooling water pumps;

[0101] Match each lifting equipment and its basic information, and assign unique coding numbers after matching;

[0102] After the unique coding number, the corresponding number of each lifting equipment is obtained.

[0103] Specifically, each lifting equipment can be clearly identified and tracked through a unique coding number, whether in the design stage, construction stage or later maintenance stage. This helps to reduce confusion and errors and improve work efficiency. At the construction site, workers can quickly find the required lifting equipment through equipment coding, reduce the time of searching and confirming equipment, and improve construction efficiency. The correspondence between equipment coding and basic information enables the quality control department to easily track the source of the equipment, production batch and other information, strengthen quality control, and ensure the overall quality of the project.

[0104] In S2, each lifting equipment is virtually constructed through the BIM model, including:

[0105] Retrieve the unique coding number of the lifting equipment, and confirm the lifting equipment and basic information of each unique coding number;

[0106] Import the lifting equipment and basic information of the lifting equipment into the BIM model to build a 3D model. After the 3D model is built, a 3D model of each lifting equipment is obtained;

[0107] At the same time, each lifting equipment is integrated into an integrated device, and after the integration is completed, the circulation pump group assembly model and the prefabricated pipe group assembly model are obtained;

[0108] Add attribute information to the three-dimensional model of each lifting equipment, where the attribute information includes material, specification, purpose, load-bearing capacity, and usage restrictions;

[0109] After the attribute information is added, the target virtual device data is obtained.

[0110] Specifically, by retrieving the unique coding number of each lifting equipment, the accuracy of the information can be ensured to avoid confusion or errors in subsequent work. At the same time, importing basic information into the BIM model for three-dimensional model construction can more accurately reflect the actual size, shape and structure of the equipment. The BIM model provides powerful visualization functions, so that the three-dimensional model of the lifting equipment can be intuitively displayed to all relevant personnel. This helps construction personnel better understand the construction plan and improve construction efficiency. By integrating the lifting equipment into an integrated equipment, the assembly model of the circulating pump group and the assembly model of the prefabricated pipe group can be obtained. This integration not only simplifies the construction process, but also helps to reduce errors and delays in construction. Through the BIM model, the performance and stability of the entire lifting system can be easily simulated and verified.

[0111] In S3, the target virtual equipment data needs to be deepened using the Revit model. After the construction deepening, the construction deepening drawing of the target virtual equipment data is obtained, including:

[0112] Retrieving construction data from the database, wherein the construction data is site data of the construction unit of the cold and heat source room hoisting equipment;

[0113] Adjust the format of the target virtual device data to be consistent with the format of the Revit model;

[0114] After the format adjustment is completed, the target virtual equipment data with the format adjustment is subjected to collision detection with the construction data through the Revit model. The collision detection is to detect whether there is a potential collision between the hoisting equipment and the site building of the construction unit;

[0115] After the collision test is qualified, the color filling of the hoisting equipment is carried out. After the color filling, the construction deepening drawing of the hoisting equipment is obtained. The construction deepening drawing includes the foundation layout drawing, equipment layout drawing, drainage ditch layout drawing, electromechanical comprehensive drawing, electromechanical professional drawing, assembly unit processing drawing, prefabricated pipe section processing drawing, and support and hanger processing drawing;

[0116] And mark the construction deepening diagram as the target construction deepening data.

[0117] Specifically, by using the Revit model to deepen the construction, it is possible to ensure that the target virtual equipment data and the construction data are accurately matched. This helps to reduce errors and rework caused by inconsistent data or misunderstandings. Using the Revit model for collision detection can more intuitively check whether there is a potential collision between the lifting equipment and the construction unit's site buildings, thereby avoiding risks in advance and reducing on-site changes and delays. Through the Revit model for construction deepening, a variety of construction deepening drawings including foundation layout drawings, equipment layout drawings, and drainage ditch layout drawings can be obtained. These drawings have a high degree of visualization and can clearly display construction details and requirements, improve the understanding and execution efficiency of construction personnel, and fill the color of the lifting equipment after the collision detection is qualified, which can not only make the construction deepening drawings more intuitive and easy to read, but also provide a practical reference for the construction site, such as marking the functions and importance of different equipment or areas. Using the Revit model for construction deepening can closely connect the various links of the project to form a complete information model. This helps the project team to work better together and improve the convenience and efficiency of project management.

[0118] In order to solve the problem in the prior art that no effective equipment inspection is performed on the hoisting equipment to be put into and into the computer room, which leads to the unqualified hoisting construction of the computer room, please refer to Figure 1 , this embodiment provides the following technical solutions.

[0119] Specifically, after the construction is deepened, the construction deepening drawing of the target virtual equipment data is obtained, which also includes:

[0120] After obtaining the construction deepening drawing, extracting the color filling parameters of the construction deepening drawing; wherein the color filling parameters include contrast, color saturation, brightness and color filling coverage;

[0121] The contrast and color saturation are used to obtain a first color filling evaluation parameter; wherein the first color filling evaluation parameter is obtained by the following formula:

[0122]

[0123] Among them, S 01 represents the first color filling evaluation parameter; n represents the number of types of drawings included in the construction deepening drawing; B i Indicates the color saturation value corresponding to the i-th type image; B 0i represents the color saturation reference value corresponding to the i-th type image; D i represents the contrast value corresponding to the i-th type image; D 0i represents the contrast reference value corresponding to the i-th type image;

[0124] comparing the first color filling evaluation parameter with a preset first parameter threshold;

[0125] When the first color filling evaluation parameter is lower than a preset first parameter threshold, a secondary color filling quality evaluation is performed on the construction deepening drawing using the color saturation, brightness and color filling coverage to obtain a secondary quality evaluation result;

[0126] When the secondary quality evaluation result shows that the color quality requirements are met, the construction deepening drawing is determined to meet the color filling quality requirements;

[0127] When the secondary quality evaluation result indicates that the color quality requirements are not met, it is determined that the construction deepening drawing does not meet the color filling quality requirements.

[0128] The technical effect of the above technical solution is: by introducing the quantitative evaluation of color filling parameters (including contrast, color saturation, brightness and color filling coverage), the quality of color filling in the construction deepening drawing can be measured more accurately. This quantitative method helps to reduce the error of subjective judgment and ensure the accuracy and consistency of color filling. By calculating the first color filling evaluation parameter using contrast and color saturation and comparing it with the preset threshold, the part where the color filling quality does not meet the standard can be quickly identified. For the part that does not meet the standard, the color saturation, brightness and color filling coverage are further used to perform a secondary color filling quality evaluation. Through this hierarchical evaluation system, the color filling quality can be more comprehensively evaluated and optimized.

[0129] At the same time, the construction deepening drawing is an important reference in the construction process, and the accuracy of its color filling directly affects the accuracy and efficiency of subsequent construction. Through the above technical solution, it can ensure that the color filling quality of the construction deepening drawing meets the requirements, thereby improving its usability and guidance in actual construction. This technical solution helps to promote the standardization and normalization of the construction deepening drawing production process by setting clear color filling evaluation standards and processes. This can not only improve construction efficiency, but also reduce the risk of construction errors and rework caused by inaccurate color filling. By regularly or irregularly evaluating the color filling quality of the construction deepening drawing, potential problems can be discovered and corrected in a timely manner, thereby supporting the continuous improvement of the construction process. This continuous improvement mechanism helps to continuously improve the quality of the construction deepening drawing and the construction efficiency.

[0130] In summary, this technical solution effectively improves the accuracy and quality of color filling of virtual equipment data in construction deepening drawings by introducing quantitative evaluation and hierarchical evaluation methods, providing a strong guarantee for the smooth progress of the construction process.

[0131] Specifically, when the first color filling evaluation parameter is lower than the preset first parameter threshold, the color saturation, brightness and color filling coverage are used to perform a secondary color filling quality evaluation on the construction deepening drawing to obtain a secondary quality evaluation result, including:

[0132] Extract color saturation, brightness, and color fill coverage;

[0133] The second color filling evaluation parameter is obtained by using the color saturation, brightness and color filling coverage; wherein the second color filling evaluation parameter is obtained by the following formula:

[0134]

[0135] Among them, S 02 represents the second color filling evaluation parameter; n represents the number of types of drawings included in the construction deepening drawing; B i Indicates the color saturation value corresponding to the i-th type image; B 0i K represents the color saturation reference value corresponding to the i-th type image; i Indicates the brightness value corresponding to the i-th type image; K 0i represents the brightness reference value corresponding to the i-th type image; P i Indicates the color filling coverage corresponding to the i-th type image;

[0136] The first color filling evaluation parameter and the second color filling evaluation parameter are used to obtain a comprehensive evaluation parameter; wherein the comprehensive evaluation parameter is obtained by the following formula:

[0137]

[0138] Among them, S represents the comprehensive evaluation parameter; S 01 represents the first color filling evaluation parameter; S 02 represents the second color filling evaluation parameter; S y represents a preset first parameter threshold;

[0139] comparing the comprehensive evaluation parameter with a preset second parameter threshold;

[0140] When the comprehensive evaluation parameter is lower than the preset second parameter threshold, it is determined that the secondary quality evaluation result does not meet the color quality requirement.

[0141] The technical effect of the above technical solution is that the technical solution not only takes into account the basic parameters of color filling (such as contrast and color saturation), but also introduces two key indicators, brightness and color filling coverage, so as to achieve a more comprehensive evaluation of the color filling quality of the construction deepening drawing. This comprehensive evaluation method can more accurately reflect the actual effect of color filling and improve the accuracy of the evaluation.

[0142] First, the contrast and color saturation are used to conduct a preliminary color filling quality evaluation (first color filling evaluation). When this evaluation result does not meet the requirements, the color saturation, brightness and color filling coverage are further used to conduct a secondary color filling quality evaluation (second color filling evaluation). This hierarchical quality evaluation system can identify problems in color filling more carefully and give more targeted optimization suggestions. By introducing comprehensive evaluation parameters, the first color filling evaluation parameters and the second color filling evaluation parameters are combined to form a more scientific comprehensive evaluation result. This comprehensive evaluation method not only takes into account all aspects of color filling, but also conducts quantitative comparison through preset parameter thresholds, making the evaluation results more objective and accurate.

[0143] By strictly evaluating the color filling quality of the construction deepening drawings, problems in color filling can be discovered and corrected in a timely manner to ensure the accuracy and reliability of the construction deepening drawings. This is crucial for the subsequent construction process, because accurate construction deepening drawings can reduce construction errors and rework risks, and improve construction efficiency and quality. This technical solution provides a systematic and operational process for the color filling quality evaluation of construction deepening drawings. By conducting color filling quality evaluation regularly or irregularly, problems and improvement points in color filling can be discovered and summarized in a timely manner, providing experience and guidance for the subsequent production of construction deepening drawings. This continuous improvement mechanism helps to continuously improve the quality of construction deepening drawings and construction efficiency.

[0144] In summary, this technical solution effectively improves the accuracy and reliability of the assessment of the color filling quality of construction deepening drawings by introducing comprehensive color filling quality assessment indicators, a hierarchical quality evaluation system and a scientific comprehensive evaluation method, providing a strong guarantee for the smooth progress of the construction process.

[0145] In S4, the data parameters in the target construction deepening data are retrieved, and the equipment is prefabricated according to the data parameters, and the prefabricated equipment is sampled, including:

[0146] Send the target construction deepening data to the prefabrication factory for equipment processing and production, where the prefabrication factory uses automated equipment for streamlined CNC processing;

[0147] When the hoisting equipment in the target construction deepening data is processed, the prefabricated components in the hoisting equipment are randomly inspected, wherein the inspection standard is to determine whether the size and color of the prefabricated components are consistent with the size and color of the corresponding hoisting equipment in the target construction deepening data;

[0148] If there is any inconsistency, adjust the parameters of the automation equipment and reprocess;

[0149] The equipment that has passed the random inspection will be marked as standard lifting equipment data.

[0150] Specifically, the precision and efficiency of equipment processing can be greatly improved by using automated equipment for streamlined CNC machining. This method is more accurate and efficient than traditional manual or simple mechanized machining, can reduce human errors, improve product quality, and conduct random inspections of prefabricated components to promptly discover and correct components that do not meet the requirements, thereby ensuring that all prefabricated components shipped meet the requirements in the target construction deepening data. This helps to reduce rework and delays caused by component quality problems and improve construction efficiency. If the size, color, etc. of the prefabricated components are found to be inconsistent with the target construction deepening data during random inspections, the parameters of the automated equipment can be adjusted and reprocessed immediately. This timely feedback and adjustment mechanism can minimize the rework rate, save time and cost, and by marking the equipment that has been successfully inspected as standard lifting equipment data, these equipment can be easily traced and managed. This helps to ensure the source and quality of the equipment and provide a reliable basis for subsequent construction and maintenance.

[0151] In S5, the construction data and standard lifting equipment data are used in the BIM model to prepare the implementation plan, including:

[0152] The construction data is used to review the deviation of civil construction by 3D laser scanning. After the deviation review of civil construction is completed, the coordinate system of the assembly room in the construction data is adjusted through the BIM model. After the coordinate system adjustment is completed, the BIM model of the assembly room under construction is obtained.

[0153] Virtually construct the standard lifting equipment data in the BIM model of the assembly room;

[0154] Among them, the circulating pump group is first virtually constructed. The circulating pump group uses a detachable turnover trestle moving track, builds a trestle between the equipment foundations, and uses a winch to pull the hoisting equipment of the circulating pump group for transportation;

[0155] Then the prefabricated pipeline is virtually constructed. When the shape of the prefabricated pipeline is irregular, it is constructed using a combined support and hanger, wherein the combined support and hanger is a combined support and hanger between the main frames of the circulating pump group;

[0156] When the prefabricated pipes are in rows or densely packed, they are assembled and constructed on the ground using prefabricated supports and hangers;

[0157] Finally, a virtual construction model with complete standard lifting equipment data in the BIM model of the assembly room is obtained;

[0158] The completed virtual construction model is implemented with a plan, wherein the plan is implemented with the virtual construction model and construction drawings are generated;

[0159] Carry out the hoisting construction of the cold and heat source room according to the generated construction drawings.

[0160] Specifically, the accuracy of the BIM model of the assembly room can be ensured by reviewing the deviation of civil construction through 3D laser scanning and adjusting the coordinate system of construction data using the BIM model. This provides a solid foundation for the subsequent virtual construction of standard lifting equipment data. The virtual construction of standard lifting equipment in the BIM model, including the virtual construction of circulating pump sets and prefabricated pipes, can detect potential design or construction problems in advance, such as collisions, size mismatches, etc. This helps to reduce errors and rework in actual construction, save time and costs, and adopt modern construction methods such as detachable turnover trestle mobile tracks and prefabricated supports and hangers, which can greatly improve construction efficiency. In addition, the use of combined supports and hangers, especially when the prefabricated pipes are irregular in shape or densely packed in rows, can more flexibly adapt to various construction scenarios, ensure construction quality and safety, and the construction drawings generated by the BIM model can intuitively display the entire process of lifting construction, including the layout of equipment, the direction of pipelines, and the installation of supports and hangers. This helps construction workers better understand the construction plan, improve construction quality and efficiency, and through virtual construction and simulation analysis, they can discover and solve potential safety hazards in advance and formulate corresponding preventive measures. In addition, the BIM model can also provide real-time safety information on the construction site, such as the identification of safety hazards and the distribution of construction workers, to improve the safety management level of the construction site.

[0161] According to the attributes of each lifting equipment in S6, on-site management is carried out when the equipment is lifted, including:

[0162] When the equipment in the generated construction drawings enters the construction site, acceptance management is carried out. Among them, acceptance management is to check the specifications, models and dimensions of the equipment entering the construction site. The equipment on-site acceptance should be jointly accepted by representatives of Party A, the supervision unit and the construction unit, and the equipment and material inspection procedures should be completed;

[0163] After the equipment is accepted, it is placed in a storage area for storage and environmental management is performed on the storage environment. Environmental management refers to storage management based on the properties of the equipment.

[0164] The reserved holes, valves and pipelines are inspected and accepted. The size, position and verticality of the reserved holes are inspected and accepted; the strength and tightness of the valves are inspected and accepted; the winding direction and tightness of the hemp on the pipeline are inspected and accepted;

[0165] The lifting construction can be carried out only after the acceptance management, environmental management, and acceptance of reserved holes, valves, and pipelines have been inspected and qualified.

[0166] Specifically, through strict acceptance management, the specifications, models, and dimensions of the equipment entering the construction site are checked to ensure that all equipment complies with the construction drawings and design requirements, thereby ensuring the quality of construction. The equipment on-site acceptance is jointly conducted by representatives of Party A, the supervision unit, and the construction unit. This can ensure the fairness and objectivity of the acceptance and avoid deviations or omissions on a single side. Storage management is carried out according to the properties of each lifting equipment to ensure that the equipment will not be damaged or deteriorated during storage, and its good performance and condition are maintained, providing strong guarantees for subsequent lifting construction. Detailed inspections are carried out on reserved holes, valves, and pipelines. Acceptance inspection, including key indicators such as size, position, verticality, strength and tightness, can timely discover potential problems and hidden dangers, avoid safety accidents or quality problems during the construction process. Through strict acceptance management and environmental management, as well as acceptance inspection of reserved holes, valves and pipelines, it can ensure that the preparations before construction are sufficient and in place, reduce problems and delays during the construction process, thereby improving construction efficiency. Comprehensive inspection and acceptance of lifting equipment, reserved holes, valves and pipelines can timely discover potential safety hazards, avoid safety accidents during lifting construction, and ensure the life safety and property safety of construction personnel.

[0167] During the hoisting construction of S7, the equipment on the construction site will be inspected for quality, and the qualification rate of the hoisting construction of the cold and hot source room will be evaluated based on the quality inspection results, including:

[0168] The quality inspection of construction site equipment includes pipeline quality inspection and circuit quality inspection;

[0169] Among them, pipeline quality inspection is to inspect the arrangement, leakage and blockage of the pipeline;

[0170] Circuit quality inspection includes the insulation status of electrical equipment and lines; installation requirements of electrical equipment and lines; grounding of electrical lines; contact protection of welding machines; and installation distance between secondary and tertiary boxes.

[0171] The pass rate of the cold and heat source room hoisting construction is evaluated based on the results of the pipeline quality inspection and circuit quality inspection.

[0172] Specifically, through detailed quality inspection of pipelines and circuits, potential safety hazards can be discovered in time, such as pipeline leakage, blockage or poor circuit insulation, so that repairs can be carried out in advance to avoid safety accidents. Quality inspection helps to ensure that every step in the construction process meets quality standards and safety requirements, thereby improving the quality of the entire lifting construction. Through quality inspection of pipelines and circuits, problems in the construction process can be discovered in time, and then the construction process can be optimized to improve construction efficiency. Through strict quality inspection in the early stage, the maintenance costs caused by equipment failure or safety hazards in the later stage can be reduced, and the economic benefits of the project can be improved.
