Bridge crack repairing method

Abstract

The invention belongs to the technical field of bridge crack repairing, and particularly relates to a bridge crack repairing method which comprises the following steps: S1, selecting an area with a crack, marking lines on two sides of the crack by adopting a steel ruler and chalk, and then carrying out width cutting treatment on the crack by adopting a cutting grinding wheel; and S2, hammering andchiseling an area cut on a bridge deck by adopting a hammer, controlling the hammering and chiseling depth to be 5-10mm, moving away a hammered and chiseled concrete slab and large-particle disintegrating slag, and erecting telescopic legs in a crack cleaning device on two sides of a wide crack. According to the invention, the crack cleaning device is arranged to clean ash and concrete residues in the crack; meanwhile, the crack cleaning device can be used for cleaning cracks with different depths and different widths, a hollow column and a cleaning plate push the cleaned ash to the moving direction of the crack cleaning device, then the ash can be collected through a dust suction pump, the whole process is convenient to operate, the labor is saved, and meanwhile, the dust flying cannot be caused.

Description

technical field [0001] The invention belongs to the technical field of bridge crack repair, in particular to a bridge crack repair method. Background technique [0002] We often pass by bridges, and we also find that every bridge has more or less cracks. Many people may not be aware of this hazard, and think that it is normal for bridges to have cracks. However, the smaller the disease is, the more fatal it is. If the cracks are allowed to develop, it will cause water seepage, which in turn will cause corrosion of the steel bars, and even affect the safety of the bridge body. [0003] When actually repairing bridge cracks, it is necessary to select an appropriate repair method according to the severity and type of the actual cracks in order to solve the fundamental problem; the bridge repair methods used in the prior art include structural reinforcement, grouting, and surface treatment. etc. Among them, a patent whose patent application number is CN201910606039.0 proposes a...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, when cleaning the cracks in the prior art, the method of manually using a dust shovel combined with a brush is often used. This cleaning method is not only labor-intensive and time-consuming, but also the process of cleaning A lot of dust will be generated in the process, which will cause damage to the health of construction workers. A bridge crack repair method proposed by the present invention
