Description

TECHNICAL FIELD

[0001] The utility model belongs to prestressed steel cylinder concrete pipe production technical field especially relates to a pipeline semi -automatic spraying maintenance device. BACKGROUND

[0002] Prestressed concrete cylinder pipe (PCCP) refers to the high-strength concrete pipe core with steel cylinder, and the dense cement mortar protective layer is sprayed on the pipe, which is made of water pipeline. It has the characteristics of high pressure resistance, corrosion resistance, high sealing, high strength and high impermeability, and is widely used in long interval water supply main line, urban water supply engineering, industrial pressure water supply main line, pressure sewage pipe and the like. The prestressed concrete cylinder pipe is mainly composed of a steel cylinder, a concrete pipe core, a prestressed steel wire and a mortar protective layer, wherein the concrete pipe core and the mortar protective layer are both cement products, and therefore, after being completed, they need to be watered for a certain period of time to accelerate the improvement of their strength and prevent dry shrinkage cracks and other quality problems. Especially in dry and windy areas, the requirement for pipeline maintenance is also higher.

[0003] The traditional watering maintenance is equipped with a plurality of full-time workers holding water pipes to water the pipeline, and the water flow is in a cluster shape, which is unevenly scattered on the outer surface of the pipeline. The water flow is sufficient in the direct radiation area, and the water splashed to other positions can also wet the surface of the pipeline, but the water flow is small, which cannot complete the penetration, and is easy to cause visual difference of workers and misjudge the maintenance degree. Moreover, after the pipeline production is completed, it cannot be immediately laid down, so the traditional watering method can only water the outer surface of the pipeline mortar protective layer, and has no effect on the maintenance of the inner wall concrete of the pipeline. The traditional watering method not only consumes time and effort, but also does not uniformly water and maintain, which is not thorough, and it is difficult to correctly maintain the pipeline, which is easy to produce dry shrinkage cracks in the later period, and the strength improvement effect of the pipeline protective layer is not significant.
