Reinforcement of prestressed slab with CFRP wrap

In view of the lack of prestressing steel wire in the prestressing hollow floor, several reinforcement schemes are analyzed and selected according to their characteristics. Decide to choose the sticky carbon fiber cloth method.

Bridge Structural Reinforcement

Because of the high strength and high elasticity of carbon fiber materials, the use of adhesives to paste them on the surface of the bridge, so that they can bear the load together with the bridge structure, can greatly improve the tensile, compressive and shear capacity of the bridge.

Carbon Fiber Reinforced Cracked Beam and Slab

The project has been effectively controlled in all aspects of CFRP reinforcement to ensure the quality of reinforcement. After carbon fiber reinforcement, the design intention has been achieved through joint acceptance by all parties, and it has received unanimous praise from Party A and supervision.

Reinforcement of pipes with carbon fiber fabric

It is an effective repairing method to reinforce steel pressure pipes by circular bonding of carbon fiber fabric. Especially for pipelines with defects, the circular stress of internal pressure pipes can be effectively reduced.

Carbon fiber fabric reinforced floor of factory building

The diameter of steel bars in the floor of the main workshop does not meet the original design requirements. The necessary reinforcement measures should be taken for the inspected workshop. After the design, carbon fiber reinforcement is finally adopted.

Bridges Strengthening By CFRP Laminates

The carbon fiber laminate with high strength or high modulus of elasticity is adhered to the surface of the concrete member of the bridge with specially configured carbon fiber glue to form a joint reinforcement method with the original member.

Comparison of Main Reinforcement Methods of Bridges

Using reinforcement method to strengthen and maintain the original bridge not only saves a lot of construction funds, but also solves the contradiction between the bearing capacity of the bridge and traffic demand in a short time. At present, the main methods used to reinforce bridges include enlarging section and reinforcing steel bar, bonding steel plate, external prestressing and carbon fiber sheet.
