Description

Technical Field

[0001] The utility model belongs to the technical field of sheet pile docks, and specifically relates to a novel tube-sheet combined dock structure. Background Art

[0002] In recent years, as the performance of steel sheet piles continues to improve, the docks with a combination of steel pipe piles and steel sheet piles are increasingly developing towards deeper water and larger scale. However, traditional steel pipe pile and steel sheet pile docks face the disadvantages of increased steel usage, durability of tie rods, and high costs.

[0003] Basalt fiber composite bars are new building materials that are made of high-strength basalt fibers and resins through pultrusion, winding, surface coating, composite molding, and continuous production. They have high strength and excellent corrosion resistance. Basalt fiber composite bars are more than three times stronger than ordinary reinforced concrete of the same specification, and their density is only about 1 / 5 of that of ordinary steel bars. The reduced deadweight improves their bearing capacity. In highway bridge construction, compared with traditional steel bars, basalt fiber composite bars have the advantages of chemical corrosion resistance, high axial tensile strength, fatigue resistance, large elastic deformation capacity, non-magnetic, and light weight.
