Device and method for strengthening bridge girder body

Abstract

The invention discloses a device for reinforcing a bridge body and a reinforcing method thereof. The device comprises a cross beam, telescopic supports are arranged at the two ends of the cross beam correspondingly, and bases are arranged at the bottoms of the telescopic supports correspondingly. A rotating roller is arranged under the cross beam and fixed to the cross beam through a fixing support, and a bottom layer resin roller brush, a leveling material drum, an impregnating resin roller brush, an impurity removing drum, a pressure drum and a carbon fiber material roller are sequentially arranged on the periphery of the rotating roller. A crack detecting unit and a range sensor are arranged on the lower portion of the middle end of the cross beam. By means of the rotating roller and the roller brushes arranged on the rotating roller, bridge body reinforcing efficiency can be improved, and manpower and time are saved; telescopic shafts are arranged to adapt to reinforcing of bridges of different heights, and meanwhile carbon fiber materials are used for reinforcing the bridge body; and the construction process is simple and convenient, the construction period is short, the cost is low, bridge bearing capacity can be improved, ductility is improved, cracks are reduced, and aging is delayed.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a device and a method for strengthening bridge beams. Background technique [0002] Highway transportation is an important part of people's logistics system, and it plays a great role in ensuring people's material needs. The bridge is an important part of road traffic and plays a very key role in the road transportation system. As the bridge will be negatively affected by rain and snow erosion, temperature expansion and contraction, etc., the health of the bridge will continue to deteriorate, the carrying capacity will continue to decrease, and even cause accidents. These problems not only affect the normal use of bridges, but also bring huge losses to the country and the people. In order to meet the needs of modern transportation and meet the requirements of bridge design specifications, these bridges must be reinforced. However, in the existing methods of strengthening bridge...

AI Technical Summary

Problems solved by technology

However, in the existing methods of strengthening bridge beams, the construction process is complicated, the construction period is long, and the price is expensive, which is not conducive to our promotion. For traditional steel reinforcement materials, we should look for a high-strength, light-weight, corrosion-resistant and durable nice new material
