Underwater bridge pier fiberglass sleeve reinforcement underwater epoxy grouting material

In the building repair and reinforcement industry, protecting underwater engineering structures has always been a challenging issue. Research and investigations have shown that structures in the splash zone, such as bridge piers, suffer particularly severe damage.For such structures, traditional repairs often use the same materials as the original construction (concrete, steel, wood) to complete the repair work, requiring cofferdams, which complicates construction and extends the timeline. Additionally, some areas cannot be cofferdammed, making construction impossible.

Since the material properties remain unchanged, it is impossible to fundamentally enhance the structure's corrosion and damage resistance. Erosion in the splash zone and damage from marine organisms persist, necessitating regular maintenance. These repairs are time-consuming, difficult to perform, and expensive.The underwater fiberglass sleeve reinforcement system combines advanced foreign technology and applications, utilizinghigh-strength, corrosion-resistant, UV-resistantfiberglass composite materialscombined withself-leveling, underwater-curingepoxy grout,and introduces the "jacketing method" model.

It addresses the technical challenges of underwater reinforcement construction for bridge piers,improving construction efficiency, reducing reinforcement costs, and enhancing corrosion resistance and durability.

Product Advantages

High Design Flexibility

Depending on the external environment of the reinforced structure, the extent of building damage, and reinforcement requirements,customized fiberglass sleeve layering, shape, thickness, etc., can be provided.Excellent Durability

Underwater epoxy grout repairs damaged structures, working in conjunction with fiberglass sleeves to form a unified whole.It can resist interactive effects caused by climate cycles, such as wet-dry, hot-cold, and freeze-thaw cycles, as well as continuous or intermittent corrosive actions from ocean tides, wastewater, electrolysis, etc., while also incorporating UV absorbers, light stabilizers, nanomaterials, etc., into the fiberglass composite materials.
