Problems solved by technology
These data show that the durability performance of the reinforced concrete structure is far from meeting the expected goals and social needs, and it also does not meet the requirements of the bridge's life-cycle economy, so there is still room for improvement

Embodiment Construction
[0066] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0067] refer to figure 1 , is a kind of concrete pasting steel plate strengthening construction technique disclosed by the present invention, comprising:
[0068] S1; surface treatment: pretreatment of the surface of the concrete to be bonded and the surface of the steel plate;
[0069] The specific steps in S1 are:
[0070] S1-1; Pretreatment of the concrete surface:
[0071] The specific steps of S1-1 are:
[0072] S1-1-1; Detect the surface condition of concrete;
[0073] S1-1-2; when the age of the concrete is more than 1 year and the surface dirt coverage area is greater than or equal to 75% or the maximum thickness of the dirt is greater than or equal to 1cm, use a hard brush dipped in a high-efficiency detergent to descale the concrete surface. Then rinse, and then polish the bonding surface, remove the 2cm-3cm surface layer until the fresh surfac...

Abstract
The invention relates to the technical field of urban construction, and particularly relates to a concrete bonding steel plate reinforcing construction process. The process comprises the following steps of S1, carrying out surface treatment; S2, carrying out unloading; S3, preparing an adhesive glue; S4, bonding a steel plate; S5, fixing and pressurizing; S6, curing: removing a clamp or a supportafter the adhesive glue is cured for 24 hours; S7, performing inspection; S8, carrying out preservative treatment: carrying out preservative treatment on the surface of the steel plate exposed in theair; S9; carrying out waterproof treatment: performing waterproof sealing treatment on a bonding seam of the steel plate and the concrete; and S10; carrying out heat insulation treatment: wrapping thesteel plate with a heat insulation material, and carrying out heat insulation treatment on the steel plate. The invention aims to provide the concrete bonding steel plate reinforcing construction process for prolonging a service life of a reinforced highway bridge.
Description
technical field [0001] The invention relates to the technical field of urban construction, in particular to a construction technique for reinforcing concrete with steel plates. Background technique [0002] With the development of my country's economy, the traffic volume is also increasing day by day. The road bridges in service period have produced various diseases after many years of operation, and many road bridges have been overloaded. Coupled with the aging of structural materials, the erosion of external corrosive environments, and overloading of vehicles, the normal performance of highway bridges continues to decline, and even leads to insufficient bearing capacity of bridge structures. Therefore, bridges and highways need to be reinforced. In my country, the commonly used method of strengthening reinforced concrete beam bridges with small and medium spans is to paste steel plates for reinforcement. [0003] The pasting method to strengthen bridges is generally to p...
