Guarding the city and strengthening flood prevention walls

The first barrier against natural disasters in Pudong New Area is the first line of seawall over 120 kilometers long and the Huangpu River flood prevention wall about 60 kilometers long, which is also an important water conservancy engineering facility. Under the comprehensive influence of factors such as time erosion, material aging, and overload, the structural safety of seawall and flood control wall engineering will gradually decrease, and irregular reinforcement treatment is needed.

The traditional reinforcement methods mainly include increasing the cross-section method, displacement reinforcement method, etc. However, traditional methods have long construction cycles, high costs, and may cause certain damage to the original structure.

Now a new reinforcement method is being used: Carbon Fiber Mesh reinforcement technology is an advanced composite material reinforcement technology. By bonding Carbon Fiber Cloth and resin together to form a strong three-dimensional network structure, and then using high-quality sprayed polymer mortar containing active ingredients for construction, it increases the strength, corrosion resistance, and stability of the building structure, effectively improves the overall performance of the structure, repairs damaged structures, and Strengthen weak areas. This technology has broad application prospects and advantages in seawall and flood control wall reinforcement projects.

The advantages of carbon fiber mesh reinforcement technology:

① Convenient and efficient construction: Carbon fiber mesh reinforcement technology requires less construction equipment and is easy to operate, which can significantly shorten the construction period and improve construction efficiency.

② High strength and high modulus: Carbon fiber has excellent mechanical properties, with higher strength and modulus than traditional steel, and is lightweight, making it easy to construct.

③ No damage to the original structure and extended service life: Carbon fiber has good stability in various corrosive environments, improves the corrosion resistance and fatigue resistance of the structure, effectively reduces the risk of structural damage caused by corrosion, does not damage the original structure, does not affect the normal use of the structure, and extends its service life.

④ Improve structural strength and stability: significantly enhance the strength and stability of embankment structures, and enhance their ability to resist natural disasters.
