Comparison of Three Different Types of Wharf Reinforcement

From the comparison of the above three different reinforcement methods, it can be seen that the structural steel bonding technology is fast and efficient, and can be completed without stopping production and less affecting loading and unloading operations. The construction process is relatively simple, the construction takes up less space, and the impact on the surrounding environment is small. The appearance of the structure after the reinforcement is basically unchanged, and it is relatively light. Because the steel plate is thin and the material is light, the weight of the structure increases very slightly, but there are certain requirements for the selection of the reinforcement and repair position. The carbon fiber reinforced concrete technology basically does not increase the weight of the original component and the size of the original component. It has the characteristics of high strength, high efficiency, easy construction quality, and excellent corrosion resistance and durability. Due to the short construction period, avoiding or reducing the shutdown time, the prominent contradiction between terminal production and construction is reduced correspondingly, and the income of production and operation of the enterprise is guaranteed accordingly.

Through engineering practice, it is proved that the structural strength and rigidity of the wharf reinforcement and reconstruction project adopts the structural bonding steel reinforcement technology, and the structural strength and rigidity can meet the design requirements. The carbon fiber reinforced concrete technology can be applied to more complex parts such as wharf beams, and has quite flexible adaptability. After testing, the main technical indicators can meet the original design requirements after using this process method for reinforcement. After the terminal was completed and put into production, it was in good condition. Therefore, this high-tech is also suitable for old wharf renovation projects. Through structural reinforcement and reinforcement, structural bearing capacity is enhanced, and it has a very wide range of promotion and application value in the field of port and hydraulic engineering.

In summary, according to different parts and production status, introducing different high and new technology and applying them to the repair of the dock structure in the port area not only has low investment, short construction period, and quick results.

This is the first time that structural bonding steel technology and carbon fiber reinforced concrete technology have been transplanted into Shanghai Harbor Wharf. Because reinforced concrete members are often affected by water level fluctuations, the final effect needs to be carefully maintained and long-term observation by the wharf manager.
