Bridge reinforcing method and device

Abstract

The invention discloses a bridge reinforcing method. The bridge reinforcing method comprises the following steps of construction preparation, pretreatment, base gel applying, carbon fiber cloth pasting, carbon fiber cloth reinforcing, and carbon fiber cloth surface treatment and detection. The cementation base gel comprises a main agent and a hardening agent, and the wight ratio is 2:1. The widthof the applied lines of the cementation base gel is 600mm, and line interval is 400mm, and therefore carbon fiber materials have high tensile strength and high anti-fatigue performance, are suitable for beam, plate and column reinforcement. Carbon fiber cloth reinforcing enables crack width to be controlled at a certain degree, and therefore width and space of the cracks are obviously decreased, the cracks are thinner, denser and shorter, so that corrosion resistance and loading capacity of concrete are improved, professional design service monitoring and safety operation management performance are further improved.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a bridge reinforcement method and device. Background technique [0002] Bridge engineering refers to the work process of bridge survey, design, construction, maintenance and verification, as well as the science and engineering technology to study this process. It is a branch of structural engineering in civil engineering. [0003] The traditional methods include enlarged section method, outsourcing steel method, and CERP confined concrete method, all of which can stably improve the bearing capacity of concrete beams, but the construction period of enlarged section method is relatively long, and the increase in component size and self-weight is relatively large. The cost of the outsourcing steel method is high, it is easily affected by the external environment, and the lateral binding force on the concrete is low, so there is no method to stably increase the strength of the build...

[0003] The traditional methods include enlarged section method, outsourcing steel method, and CERP confined concrete method, all of which can stably improve the bearing capacity of concrete beams, but the construction period of enlarged section method is relatively long, and the increase in component size and self-weight is relatively large. Large, the cost of the outsourcing steel method is high, it is easily affected by the external environment, and the lateral restraint force on the concrete is low, so there is no method to stably increase the strength of the building structure, and the bridge is generally built on the river, and the construction process requires a station position Scaffolding is more difficult to build
