Construction technology for pasting carbon fiber cloth in repairing process of bridge crack

Abstract

The invention discloses a construction process for pasting carbon fiber cloth in repairing bridge cracks. The carbon fiber cloth is cut according to the size required by the design. Before construction, the surface moisture content of the concrete at the pasting part and the ambient temperature are measured, and the reinforced components are removed. On the loose part of the surface, until the concrete structure layer is exposed, the prepared adhesive is evenly applied to the concrete surface of the part that needs to be pasted, and the cut carbon fiber cloth is applied on the base layer coated with the adhesive. The primer should be roller brush or special The brush is evenly applied on the concrete surface that has been wiped clean with acetone, and the special roller is used to roll the surface of the carbon fiber cloth several times along the fiber direction. It will not fall under the environment, and the cracks have been repaired to ensure the service life and safety of the bridge.

Description

technical field [0001] The invention relates to a technology, in particular to a construction technology for pasting carbon fiber cloth in repairing bridge cracks. Background technique [0002] A bridge refers to a building erected on rivers, lakes and seas to enable the smooth passage of vehicles and pedestrians. It is called a bridge. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the bridge head board, conical slope protection, bank protection, diversion works, etc. Bridges are actually divided into three categories: girder bridges, arch bridges and suspension bridges, and cable-stayed bridges. Girder bridges are generally ...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the above-mentioned existing poor sticking effect on carbon fiber cloth, resulting in poor coverage of cracks, easy to fall off after a period of use, causing cracks to be exposed, cracks will continue to expand, and cause hidden dangers to the safety of the bridge. A construction process for pasting carbon fiber cloth in the repair of bridge cracks is designed. The operation steps of this process are simple and can ensure that the carbon fiber cloth is tightly pasted and will not fall off in the natural environment. The cracks are repaired to ensure The service life and safety of the bridge solve the problem that the existing poor sticking effect of carbon fiber cloth leads to poor coverage of cracks, and it is easy to fall off after a period of use, causing cracks to be exposed, and the cracks will continue to expand, causing hidden dangers to the safety of the bridge question
