BIM (Building Information Model)-based pipe prefabrication method

Abstract

The invention relates to a BIM (Building Information Model)-based pipe prefabrication method, which comprises the followingsteps: (1) performing three-dimensional modeling, i.e., converting a two-dimensional design drawing into a corresponding BIM three-dimensional model; (2) performing collision detection, i.e., performing collision detection on the three-dimensional model by using a pipeline model-based collision detection algorithm until the collision result is zero collision, and outputting a final three-dimensional model; (3) prefabricating and pretreating, i.e., numbering all pipe sections in the three-dimensional model according to an assembly sequence and outputting and printing a prefabrication drawing and a numbering result; and (4) prefabricating, i.e., manufacturing a pipe prefabricated part according to the prefabrication drawing and the numbering result. Compared with the prior art, the pipe prefabrication method has the advantages that the prefabrication accuracy can be improved, the field working efficiency is improved and the like.

Description

technical field [0001] The invention relates to a pipeline prefabrication processing technology, in particular to a BIM-based pipeline prefabrication method. Background technique [0002] At present, BIM technology has been used abroad to achieve the prefabrication processing and on-site installation of pipelines. Our country has just started in this area. In recent years, this technology has also been implemented in some major national-level projects. However, the degree of prefabrication is still far behind that of civil engineering, steel structure, glass curtain wall and other industries, especially electromechanical. The pipeline welding technology in the installation project has not made a major breakthrough in recent years, and it still stays in the operation mode stage of on-site welding production. [0003] Due to the characteristics of large pipe diameters, complex materials, different wall thickness series, and large welding work volume, pipeline engineering is a...

AI Technical Summary

Problems solved by technology

[0003] Due to the characteristics of many pipe diameters, complex materials, different wall thickness series, and large welding work volume, pipeline engineering is affected by many constraints such as material supply, equipment delivery safety, climate conditions, and on-site operating surfaces during the construction process. , especially in the large amount of welding in the pipeline connection, the pipeline layout is not accurate enough under the traditional engineering design method, which leads to a low degree of prefabrication. A large number of operating workers has brought a certain amount of pressure to the daily management of the site

Secondly, the on-site environment is relatively complicated, the work interface is chaotic, and the work efficiency of workers is low

Furthermore, on-site processing must require a lot of fire points, which undoubtedly increases the safety hazards on site.
