Steel pile anticorrosion operation equipment

Abstract

The invention discloses steel pile anticorrosion operation equipment, which comprises an operation well, a drainage device, a vertical walking mechanism, a circumferential scanning mechanism, a surface treatment device, a spraying device and a propelling bin, wherein the operation well can float on the water level, the center of the operation well is provided with a cavity, the operation well consists of at least two valves capable of being switched, the switched operation well can encircle a steel pile, and the top and the bottom of the cavity are provided with sealing devices which can form seal together with the surface of the steel pile; the vertical walking mechanism is positioned in the cavity of the operation well and can move up and down; the circumferential scanning mechanism is arranged on the vertical walking mechanism and can move in the cavity of the operation well along the circumference; the surface treatment device is connected with the circumferential scanning mechanism and can clean the surface of the steel pile; the spraying device is connected with the circumferential scanning mechanism; and two independent driving devices are arranged in the propelling bin and connected with two propellers respectively. The equipment can finish a full secondary anticorrosion process of the steel pile, and provides a reliable operation environment and an effective operation means for anticorrosion maintenance of the marine steel pile.

Description

technical field [0001] The invention relates to maintenance equipment for steel piles on water, in particular to equipment capable of performing anticorrosion operations on offshore steel piles. Background technique [0002] The steel pile is the main load-bearing component of the wharf. Its corrosion seriously affects the safety and service life of the wharf, so it must be effectively protected. Steel pipe piles in seaports and wharfs are generally protected by a combination of coating and cathodic protection, cathodic protection can also be used for underwater areas, and anti-corrosion coatings can be used for protection above the tidal range area. It is generally believed that as long as the anti-corrosion coating protection zone and the water electrochemical protection zone are well connected, no blank space is left in the middle. There is a lack of consistent electrolyte in the tidal zone, and cathodic protection cannot function part of the time. Therefore, the coatin...

AI Technical Summary

Problems solved by technology

However, due to the harsh corrosion environment, the anti-corrosion facilities of the steel structure of the seaport wharf usually fail after 8 to 10 years of operation. Ions make the average corrosion rate of wharf steel piles reach 0.3-0.4mm / year, and the local corrosion rate even reaches 1mm / year; at the same time, marine organisms living in tidal range areas will also accelerate the corrosion rate of steel piles
