What is a fiberglass sleeve?

Underwater structural reinforcement projects play an important role in marine engineering and urban infrastructure maintenance. As key materials in underwater reinforcement, fiberglass sleeves, underwater epoxy grouting materials and epoxy sealants have the characteristics of corrosion resistance, high strength and long life, and have been widely used in engineering practice. This article will introduce the characteristics, selection principles and corresponding construction methods of these materials.

Fiberglass sleeve is a structural material used for underwater reinforcement. Its main components are fiberglass and resin. It has excellent corrosion resistance, high strength and good flexibility, and can effectively increase the bearing capacity and seismic performance of the structure. When selecting fiberglass sleeve, the following factors should be considered:
1. Strength and stiffness: Select the appropriate strength and stiffness level according to the actual engineering needs.
2. Diameter and length: Determine the appropriate sleeve diameter and length according to the size of the reinforced structure.
3. Corrosion resistance: Ensure that the fiberglass sleeve can withstand the erosion of chemicals and seawater in the underwater environment.
