Continuous counterweight concrete coating and curing agent online spraying equipment and method for sea pipes

Abstract

The invention discloses continuous submarine pipeline counterweight concrete coating and curing agent online spraying equipment and method. The equipment comprises a pipe inlet device, a counterweightcoating rail, a counterweight coating trolley, a counterweight concrete spraying and coating system, curing agent spraying systems, an industrial personal computer and a pipe outlet device. The industrial personal computer is connected with the counterweight coating trolley, the counterweight concrete spraying and coating system and the curing agent spraying systems. According to the invention, the curing agent spraying systems are mounted on the two adjacent sides of the counterweight concrete spraying and coating system; counter weight concrete spraying and coating control and curing agentonline spraying control are associated and integrated; the on-line continuity and synchronous matching performance of concrete spraying and coating operation and curing agent spraying operation are guaranteed; the overall automation level and construction efficiency are improved; and large-scale application of the novel curing agent curing technology in the field of submarine pipeline spraying type counterweight concrete is achieved.

Description

technical field [0001] The invention relates to the processing and manufacturing technology of concrete counterweight pipes, in particular to a construction equipment and method for continuous sea pipe counterweight concrete spray coating and curing agent online spray coating. Background technique [0002] At present, at home and abroad, the sprayed concrete counterweight coating on the outside of the pipeline is mainly used for the counterweight of the sea pipe to overcome the buoyancy of the seawater on the pipeline, and at the same time protect the steel pipe and the anti-corrosion and thermal insulation coating. In the entire construction process of sprayed concrete counterweight coating for sea pipes, the maintenance of concrete takes up the most time, which is one of the key links to ensure the forming effect and performance of counterweight coating. For a long time, the maintenance of domestic subsea pipeline concrete counterweight coating has been covered by the trad...

AI Technical Summary

Problems solved by technology

[0003] 1) The start and end of wrapping are manually operated by workers, and the degree of automation is low;

[0004] 2) The on-site wrapping operation is close to the dangerous area of ​​concrete coating, the working environment is poor and the safety risk is high;

[0005] 3) Quality links such as the tightness and lap width of the wrapping film are not easy to control, resulting in a large workload for subsequent repairs;

[0006] 4) The post-form removal process requires a certain amount of manpower and material resources;

[0007] 5) Demolition produces a large amount of waste plastics, causing "white pollution"
