Repair method of bridge component collision damage

Abstract

The invention discloses a bridge component collision damage restoration method, and belongs to the technical field of bridge restoration. The method comprises the following steps that a collision damage position is carefully inspected; if the collision only occurs on the surface, a damage party can perform repair operation; then, broken and loose concrete in the collision damage position can be chiseled away; deformation or fracture steel bars and steel twisted lines are connected and are subjected to anti-rust treatment; then, epoxy resin glue liquid used for glue bonding is brushed and coated on the surfaces of the steel bars and steel twisted lines; after bubbles of the epoxy resin glue liquid to be brushed and coated are eliminated, a mixture of epoxy mortar and high-intensity concrete can be gradually and compactly loaded into the repair region in a small amount and multilayer mode; leveling is performed; then, after the initial set of the mixture, a steel plate in the proper shape is cut according to the fold line length of the damaged edge and corners of the collision position; the collision damage position is subjected to corner covering treatment; then, the steel plate surface is subjected to paint brushing anti-rust treatment; warning paint is brushed and coated. The method is used for performing fast, effective and practical restoration on a bridge.

Description

technical field [0001] The invention relates to a method for repairing crash damage of bridge components, which belongs to the technical field of bridge repair. Background technique [0002] Concrete structures or steel-concrete structures are famous for their durability, but they are often damaged to varying degrees during the application process due to various factors, including the influence of construction, unreasonable factors in design, and later vehicle use, etc. Various diseases. [0003] Although the surface defects of reinforced concrete bridge structures will not cause major safety accidents such as collapse in a short period of time, it does not mean that the appearance and surface defects are not harmful. Various bridge accident surfaces, some appearance and surface damage will gradually lead to construction The internal development of the bridge has caused a series of hazards, such as the increase in structural deformation and the decrease in the strength of r...

[0003] Although the surface defects of reinforced concrete bridge structures will not cause major safety accidents such as collapse in a short period of time, it does not mean that the appearance and surface defects are not harmful. Various bridge accident surfaces, some appearance and surface damage will gradually lead to construction The internal development of the bridge has caused a series of hazards, such as the increase in structural deformation and the decrease in the strength of reinforced concrete, which endanger the normal operation and safe use of the bridge structure. more and more attention
