Zinc is soluble in acids and alkali, so it is called an amphoteric metal. Zinc changes little in dry air. In moist air, a dense basic zinc carbonate film forms on the surface of zinc. In the atmosphere containing sulfur dioxide, hydrogen sulfide and Marine atmosphere, zinc corrosion resistance is poor, especially in the high temperature and high humidity atmosphere containing organic acid, zinc coating is easily corroded. The standard electrode potential of zinc is -0.76V, for the steel substrate, zinc coating belongs to the anodic coating, which is mainly used to prevent the corrosion of steel, and its protective performance is greatly related to the thickness of the coating. The protection and decoration of zinc coating can be improved significantly after passivation, dyeing or coating with light protector.

The steel sheet pile is a steel structure with a linkage device at the edge, and the linkage device can be freely combined to form a continuous and tight retaining wall or retaining wall. Steel sheet pile products are divided into two types according to the production process: cold-formed thin-wall steel sheet pile and hot-rolled steel sheet pile. In engineering construction, the application range of cold-formed steel sheet pile is relatively narrow, mostly as a material supplement for application, and hot-rolled steel sheet pile has been the leading product for engineering application.

Advantages of steel sheet pile:

With strong bearing capacity and light structure, the continuous wall composed of steel sheet piles has high strength and rigidity.

Good water tightness, steel sheet pile joint lock tight, can be natural seepage.

The construction is simple, can adapt to different geological conditions and soil quality, can reduce the excavation amount of soil, and the operation occupies a small site.

Good durability, depending on the difference in the use environment, the life can be up to 50 years.

Construction environmental protection, the amount of soil and concrete consumption is greatly reduced, which can effectively protect land resources.

The operation is efficient, and it is very suitable for the rapid implementation of flood control, collapse, quicksand, earthquake and other disaster relief and prevention.

The material can be recycled and reused, and can be reused 20 to 30 times in temporary projects.

Compared with other monomer structures, the wall is lighter and has a greater ability to adapt to deformation, which is suitable for the prevention and treatment of various geological disasters.
