U-shaped beam body integrated spray maintenance system and method

Abstract

The invention discloses an integrated spraying maintenance system and method for a U-beam body. The system comprises a water supply pipeline arranged inside a U-beam. The water supply pipeline comprises a first pipeline which is roughly arranged along the center of an inner bottom plate of the U-beam. The first pipeline is provided with a plurality of branched second pipelines. The second pipelines are provided with a plurality of sprayers used for spraying the inner surface and outer surface of the U-beam. According to the integrated spraying maintenance system and method, the water supply pipeline is arranged inside the U-beam, a water supply control system is used for controlling the water supply pipeline to be on and off, and maintenance liquid is sprayed out of the sprayers for maintenance of the U-beam; there is no need to hold the pipeline with hands for spraying, spraying is even, and time consumption is short; the second pipelines are matched with fourth pipelines so that the inner side and outer side of an outer web of the U-beam can be effectively sprayed; meanwhile, the maintenance liquid sprayed to the outer web of the U-beam flows to a low position from a high position and can meet the flowing direction requirement of liquid, repeated spraying is reduced and maintenance precision is high.

Description

technical field [0001] The invention relates to the spray maintenance of U-shaped beams, in particular to an integrated spray maintenance system and method for U-shaped beams. Background technique [0002] Urban rail transit is an important growth point for China's future economic development, and it is also a symbol of the development of large and medium-sized cities in China. The development of urban rail transit is the most effective and fundamental way to solve urban road congestion and reduce smog. The U-shaped beam introduces the international advanced design concept, and the closed box girder is designed as a new structural form of a thin-walled open U-shaped concrete beam, and the train runs inside the open U-shaped beam. U-beams not only have a beautiful appearance and reduce the overall structural height, but also have a light and thin structural concrete, relatively low cost, and have great advantages in noise reduction and shock absorption. With the development...

Problems solved by technology

[0006] In view of the above problems, in order to solve the deficiencies of the existing technology, an integrated spray maintenance system and method with a high degree of automation and high maintenance precision is specially set up to fill the gap in the maintenance method of U beams and solve the problems caused by manual maintenance methods such as traditional box girders. There are problems such as untimely maintenance, uneven spraying, inadequate spraying, poor randomness and repeatability, long time consumption, high labor intensity, and poor maintenance accuracy.
