Description

Technical Field

[0001] The utility model relates to the technical field of steel sheet pile protection, in particular to a sacrificial anode used for steel sheet piles. Background Art

[0002] The ocean has huge economic benefits and an important national defense status. Ocean-related construction projects have been booming in recent years. Steel sheet piles are widely used in permanent structural buildings (piers, unloading yards, embankment revetments, breakwaters, diversion dikes, docks, gates) and temporary structures (temporary bank expansion, bridge cofferdams) because of their high strength, good water-proofing, strong durability, reusability, and the ability to significantly reduce the construction costs of marine projects and shorten the construction period. The main materials of steel sheet piles include carbon steel and low-alloy steel, which will suffer severe corrosion in seawater media (usually containing ~20,000pp chloride ions). Corrosion protection of steel sheet piles is the key to improving their service life.

[0003] The existing sacrificial anodes for steel sheet piles, when in use, need to manufacture a matching mounting frame when installing the sacrificial anodes because the sizes of the steel sheet piles are uniform. The installation process is relatively cumbersome and inconvenient to install. In addition, the connection between the sacrificial anode and the steel sheet pile is not firm enough, and gaps or oxide layers are easily formed in the middle, which affects the normal operation of the anode.
