Application Research On Comprehensive Technology Of Super High-rise Building Pipeline Based On BIM

With the rapid development of China's economy and society,demands for super high-rise buildings has shifted from reducing land occupation and increasing building capacity to comfort,appearance and energy saving.In this situation,the pipeline system is more complicated,and the comprehensive design of the pipeline is more difficult.The traditional work mode for pipeline integration of super high-rise buildings cannot intuitively reflect the spatial arrangement of the pipeline,which results in many intersections,high frequency of changes,poor drawing consistency and other issues.In recent years,BIM technology has been vigorously promoted in C hina,and a number of classic cases of BIM technology application have emerged.BIM technology has the characteristics of visibility,collaboration,parameterization,and plotability,which can improve the comprehensive design quality of pipelines,reduce design changes and the frequency of construction rework to save project costs.However,the conventional BIM application process for pipeline synthesis of super high-rise bui ldings has the defects of poor implementability and low system operation guarantee.In addition,the determination of pipeline comprehensive schemes is highly subjective and lacks quantitative analysis.The traditional working mode and BIM working mode in the pipeline synthesis process has been researched respectively,and analyzes the limitations of the traditional working mode and the advantages of BIM technology.Secondly,it improves the conventional BIM application process of pipeline comprehensive technology in the hydraulic calculation process.Secondly,it improves the BIM application process of pipeline comprehensive technology.In the hydraulic calculation link,the BIM technology was used to calculate the hydraulic loss of the wind system and water system.Based on this,it was checked whether the related equipment mets the operating requirements;besides,from the project cost,pipeline hydraulic loss,the difficulty of construction,and the comprehensive optimization effect of the pipeline are used to construct a pipeline comprehensive scheme evaluation model with fuzzy mathematics theory,which provides a theoretical basis for the comparison and selection of pipeline comprehensive schemes.Finally,to verify the feasibility of BIM application process and pipeline comprehensive scheme evaluation model established in this paper,taking a super high-rise building as example,a total of three pipeline comprehensive schemes were proposed for electromechanical pipeline on a floor,and the best optimization scheme was selected with established evaluation model.The results show that the BIM technology application process established in this paper is more implementable than the conventional process;and 8 design errors in the two-dimensional drawings are discovered and fixed which avoid related engineering changes during model building with BIM technology,and saves 85,000 yuan of cost approximately;during the pipeline synthesis stage,the fuzzy comprehensive decision method applies to determine the optimal model of pipeline arrangement,and the collision detection is performed with BIM technology,and a total of 1428 collisions are discovered and eliminated,which decreased almost 78%collisions of original design and saves the design cost of 362,000 yuan;during the construction stage of project,the design and processing details of the pipeline comprehensive support and hanger are completed in the BIM model according to the relevant design and construction acceptance specifications and provide the guidance to pre-production and on site installation of pipeline hangers which saves 457,000 yuan of project cost.During the entire project,the BIM technology and fuzzy comprehensive decision-making method saved a total cost of 904,000 yuan in the pipeline layout,which accounting for 6.8%of total cost.
