Embodiment 1

[0021] Example 1, such as figure 1 As shown, the PCCP anti-corrosion automation platform includes a rotating platform 1, a lifting track 2, a hoist 3, a spraying machine 4, a high-pressure gas nozzle 5, an anti-corrosion spraying gun head 6, and a hoist; the lifting track 2 stands on the side of the rotating platform 1, and the hoist 3 is installed on the lifting rail 2 that can slide up and down; the high-pressure gas nozzle 5 and the anti-corrosion spray gun head 6 are installed on the hoist 3; the high-pressure gas nozzle 5 is connected to a high-pressure gas source through a hose, and the anti-corrosion spray gun The pipe is connected to the sprayer 4; the hoist 3 is connected to the hoist.

[0022] The rotary platform 1 can adopt the foundation base of the PCCP pipe shotcrete machine. Lifting track 2 and hoist 3 are existing known public technology. Sprayer 4 can adopt two-component high-pressure airless spraying equipment. The anti-corrosion spraying gun head 6 is a t...

Embodiment 2

[0030] Example 2, such as figure 1 As shown, an anti-corrosion spraying method includes the following steps: first step, pour the anti-corrosion paint into the sprayer 4 and stir it fully, and wait for spraying; Turn the rotating platform 1; the third step is to connect the high-pressure gas source, and use the high-pressure gas nozzle 5 to clean up the dust, cement slurry and other debris on the surface of the pipe; the fourth step is to turn on the spraying machine 4 and extend the anti-corrosion spraying gun head The surface of the pipe is sprayed, and the lifting speed of the hoist 3 is controlled by the lifting hoist to match the rotation speed of the rotating platform 1, so that the spraying belt sprayed on the pipe is more than one-third of the width and the adjacent spraying belt is superimposed; the fifth The first step is to finish the spraying and measure the thickness of the anti-corrosion coating with a paint film thickness meter after it has dried.

Abstract

The invention relates to a PCCP (prestressed concrete cylinder pipe) protective layer anti-corrosion coating construction operation device and method, in particular to a PCCP anti-corrosion automatic platform and an anti-corrosion spraying method. The device comprises a rotating platform, a lifting track, a lifting machine, a spraying machine, a high-pressure gas spray head, an anti-corrosion spraying gun head and a lifting winch; the lifting rail is erected beside the rotating platform, and the lifting machine is installed on the lifting rail in an up-and-down sliding mode. Due to the implementation of the technical scheme, along with low-speed rotation of the rotating platform, the spraying machine works, the anti-corrosion spraying gun head sprays the surface of a pipe, the lifting speed of the lifting machine is controlled by the lifting winch to be matched with the rotating speed of the rotating platform, and more than one third of the width of a spraying belt sprayed on the pipe is overlapped with an adjacent layer of spraying belt; one-time spraying forming is carried out; the problems of material waste and labor investment caused by a manual painting mode are solved, the labor productivity is improved, the production cost is reduced, and the product quality is improved.

Description

technical field [0001] The present application relates to a PCCP pipe protective layer anti-corrosion coating construction operation device and method, in particular to a PCCP anti-corrosion automatic platform and anti-corrosion spraying method. Background technique [0002] Prestressed Steel Cylinder Concrete Pipe (PCCP) is a pipe made of a concrete core with a steel cylinder wound with a hoop prestressed steel wire and a cement mortar protective layer. PCCP pipes are buried in the ground, and the outer surface is subject to corrosion factors in the soil, such as chloride ions and water in saline-alkali soil, which penetrate into the mortar protective layer, causing the steel wire to rust, age and break, causing the pipe to burst. [0003] Therefore, in most water diversion projects using PCCP pipelines, mortar protective layer anti-corrosion work (epoxy coal tar pitch anti-corrosion paint) is required to isolate harmful substances and water in the soil from penetrating the...
