Problems solved by technology
[0004] However, due to the different damage conditions of bridges, it is not appropriate to simply use a certain repair agent or a certain repair method
Most of the existing repairing agents or maintenance methods are aimed at a specific situation, and there is still a lack of effective repairing agents and maintenance methods for bridges with multiple damage defects

Embodiment
[0033] Such as figure 1 As shown, the present invention discloses a method for repairing a bridge using concrete for bridge repair. Repair bridges.
[0034] Generally speaking, cracks commonly exist in bridges to be repaired. Therefore, the cracks of the bridge to be repaired are first repaired with the expansive concrete layer of the beam repair concrete, and then the water reducing agent layer is laid.
[0035] figure 2 Furthermore, the method of corresponding repair measures is given according to the basic situation of the bridge, especially the clearance height under the bridge and the height of the main girder.
[0036] Of course, the basic situation also includes the service life, design life and crack condition of the bridge to be repaired;
[0037] Specifically, take corresponding remedial measures according to the following standards:
[0038] If the under-bridge clearance height of the bridge to be repaired is higher than the first threshold, or the girder heigh...

The invention discloses a method for repairing a bridge by using bridge repairing concrete and relates to the field of bridge repairing. The method for repairing the bridge by using the bridge repairing concrete comprises the steps of 1, determining the basic situation of a bridge to be repaired, wherein the basic situation comprises underbridge clearance height, main beam height, service life, designed life and crack status; and 2, repairing the bridge by using the bridge repairing concrete according to the basic situation of the bridge to be repaired. The method for repairing the bridge by using the bridge repairing concrete has the advantages that the bridge can be effectively maintained and repaired; and meanwhile, a reinforced concrete structure is easy to realize, can be constructedon site and can also be made into a prefabricated member; layered construction and the construction of the prefabricated member are carried out according to the actual situation of the bridge to be repaired so that the influence on the existing traffic is furthest reduced.
Description
technical field [0001] The invention relates to the field of bridge repairs, in particular to a method for repairing bridges with bridge repair concrete. Background technique [0002] Due to the complex geographical environment of our country, with many mountains and rivers, a large number of bridges usually need to be built during the construction of railways and highways, and in urban traffic, a large number of overpasses also need to be erected to improve traffic. However, with the increasing traffic load, the driving density of vehicles is increasing, and the load tonnage of vehicles has gradually increased. Due to historical reasons, the load, length, and width of various bridges originally built have gradually decreased. At the same time, due to the increase of traffic flow, many bridges that have not yet reached the design life have various damages to varying degrees, which endangers traffic safety. [0003] In response to these problems, technicians usually have two...
