Assembling construction method for pipeline of refrigerating machine room of subway station

Abstract

The invention provides an assembling construction method for a pipeline of a refrigerating machine room of a subway station, and belongs to the technical field of subway machine room installation. Themethod comprises the following steps of 1, establishing and optimizing a BIM model; 2, decomposing a construction model; 3, determining an assembly scheme; 4, prefabricating the pipeline; 5, installing a pipeline support; 6, assembling the machine room pipeline; 7, performing heat preservation and fabricating outer protection; and 8, spraying a color ring mark. According to the method, the BIM building model is adopted, the construction environment is simulated, the pipeline arrangement is optimized, and field installation is facilitated; all water pipes involved adopt a factory prefabrication mode, so that the cutting and welding operation is avoided, the material utilization rate is effectively increased, and the field potential safety hazard and the environmental pollution are reduced;the water pipes adopt an assembling mode, so that the field installation construction is facilitated, the site limitation problem of construction in the limited space of a subway can be solved; and the construction period is shortened.

Description

technical field [0001] The invention belongs to the technical field of subway machine room installation, and specifically discloses a construction method for assembling pipelines of a refrigeration machine room in a subway station. Background technique [0002] At present, the pipeline installation and construction of the refrigerator room of the subway station is made and installed on site through the design of the blueprint. The above-mentioned installation and production method is limited by the construction environment of the subway refrigeration room, and relies heavily on on-site measurement. The plan drawings cannot reflect the construction environment and intersection. The main problems are as follows: [0003] 1. The measurement, cutting, beveling, assembly and welding of the pipeline are all completed on site, and the quality of pipeline installation cannot be guaranteed; [0004] 2. On-site processing materials are wasteful, cutting and welding operations are ris...

AI Technical Summary

Problems solved by technology

The above-mentioned installation and production method is limited by the construction environment of the subway refrigeration room, and relies heavily on on-site measurement. The plan drawings cannot reflect the construction environment and intersection. The main problems are as follows:

[0003] 1. The measurement, cutting, beveling, assembly and welding of the pipeline are all completed on site, and the quality of pipeline installation cannot be guaranteed;

[0004] 2. On-site processing materials are wasteful, cutting and welding operations are risky, and on-site welding operations increase safety risks;

[0005] 3. Serious dependence on design drawings, limited by the quality of personnel, many cross-cutting problems, easy to return to the factory for dismantling and modification, long cycle and inflexible methods;

[0006] 4 The secondary galvanizing treatment at the welding joint is difficult, the process level is uneven, there is a large risk of corrosion, and the quality cannot be guaranteed;

[0007] 5 Large-scale construction operations are concentrated on the site, and there are difficulties in site storage and turnover in the limited underground space
