Problems solved by technology

The existing multi-layer protection method lacks inspection methods. The protective layer can be visually inspected in the case of obvious damage. However, once the damage that is not easy to see occurs, seawater entering the protective layer will form a new corrosion environment, which is often more serious. In addition, the existing multi-layer protection method has single measures and lacks failure emergency protection measures. Once the protection layer is damaged, seawater enters the inside of the protection layer. Without emergency protection, corrosion can only be allowed to develop, and can only be repaired after the problem is found to stop

Embodiment approach

[0029] like figure 1 As shown, the anticorrosion layer 2 is coated or bound on the steel structure 1 first, then the spiral sacrificial anode 3 is wound outside the anticorrosion layer 2, and the wires 4 and Wire 5, and then install protective shell 6 in the splash protection area, and the end sealing completes multi-layer protection. Weld the terminal box 7 on the upper part of the platform structure, connect the two ends of the sacrificial anode to the wire 4, one end of which is connected to the first terminal 8, the other end to the second terminal 9, and the third terminal 10 is directly connected to The steel structure body 1 is electrically connected.

[0030] During normal use, the first terminal 8, the second terminal 9 and the third terminal 10 are connected by wires to realize the electrical connection between the sacrificial anode 3 and the steel structure 1. When the multi-layer protection is damaged to the anticorrosion layer 2 When , the sacrificial anode 3 an...

Abstract

The invention discloses a multi-layer protective monitoring and emergency guaranteeing system for a steel structure in a splashing region. The system comprises a vaseline corrosion-resistant inner layer and a glass reinforced plastic outer protecting armor layer, and further comprises a spiral striped sacrificial anode and testing equipment; the sacrificial anode winds the outer side of the vaseline corrosion-resistant inner layer, the outer side of the sacrificial anode hermetically encompasses the outer protecting armor layer, and the two ends of the sacrificial anode are connected with a conducting wire and lead the conducting wire out of the glass reinforced plastic outer protecting armor layer, and are respectively and electrically connected with a steel structure main body; the testing equipment is used for testing the on / off state of the sacrificial anode and the current between the sacrificial anode and the steel structure main body. The invention further discloses a multi-layer protective monitoring and emergency guaranteeing method for the steel structure in the splashing region. The system and the method, provided by the invention, have the advantages as follows: on one aspect, the water inflow condition of a protective layer can be monitored, and the validity of the protective layer is judged; on the other aspect, once the protective layer is broken, the capability of emergency security is provided to maintain the corrosion protecting capability for a period of time to make time for maintenance.

Description

technical field [0001] The invention relates to a steel structure multi-layer protection system and method, in particular to a steel structure multi-layer protection monitoring and emergency support system and method in a splash zone. Background technique [0002] The marine steel structure is expensive, bears and transmits loads, and runs through the atmospheric area, splash area, tidal range area, full immersion area and sea mud area. The steel structure is corroded by the sea atmosphere and seawater, especially in the splash zone, which is also subjected to seawater splash and tide. The coating in this area is easily damaged and is not protected by cathodic protection, so the corrosion problem is particularly serious. Corrosion is a typical degradation risk mode, and as more and more offshore steel structures approach or exceed the original design life, the corrosion problem will become more and more serious. [0003] At present, the protection technology applied in the ...
