Abstract

The invention discloses a factory prefabrication construction method for pipelines. The method comprises the following steps that 1, a three-dimension preassembly model of the pipelines is built; 2, the pipeline prefabrication degree is determined, drawing optimization is completed with a computer, pipeline and pipe fitting manufacturing units are determined, and a machining drawing is drawn out; 3, a pipeline factory assembly line machining process is made according to the machining drawing, and then according to the determined machining process, a prefabrication site is planned, and prefabrication devices are arranged; 4, a pipeline machining prefabrication factory is selected; 5, the prefabrication factory carries out factory machining prefabrication on the pipelines according to the machining drawing, and 6, the prefabricated pipelines and pipe fittings are transported to a construction site for installation, specifically, the prefabrication devices comprise the lifting pipeline prefabrication bracket. According to the factory prefabrication construction method for the pipelines, machining prefabrication is not affected by weather and conditions of the construction site, and through the factory production mode, the manufacturing cost is lowered, the construction efficiency can be improved, labor allocation on the site is relieved, and construction quality and safety of constructors can be guaranteed.

Description

technical field [0001] The invention relates to a pipeline construction method. More specifically, the present invention relates to a factory-like prefabrication construction method for pipelines. Background technique [0002] In the construction of modern petroleum, petrochemical, and chemical plants, it is well known that there are many types of pipeline installation projects, complex materials, heavy workload, and long construction period. About 50% of the total man-days of construction. With the progress of construction technology, the wide application of large cranes, high-efficiency automatic welding, factory prefabrication of steel structures, and the improvement of equipment manufacturing technology and service level, the problems of equipment installation, non-standard manufacturing and steel structure installation that restricted the construction period in the past have been solved. Better solution, and the degree of influence of the pipeline installation constru...
