Technical Field

[0001] The utility model relates to the technical field of road and bridge crack repair, in particular to a municipal engineering road and bridge crack repair fixing structure. Background Art

[0002] In the prior art, the repair method of road cracks is generally selected according to the size and severity of the cracks. Grouting method: For cracks with a width of less than 6mm, the grouting method can be used directly for repair. First, clean the debris and dust in the crack, and then evenly pour the repair filler into the crack to achieve the purpose of repair; for larger cracks or serious damage to the road surface around the crack, the digging method can be used for repair; first, dig out the damaged part of the crack and the road surface around it, and then fill it with new materials and compact it to achieve the purpose of repair.

[0003] However, this type of repair method in the prior art is to simply fill the pothole with cement and then cover the top of the cement with asphalt. There is no supporting structure inside the pothole, which easily leads to poor strength after the pothole is filled. Therefore, in order to address this problem, it is necessary to improve a municipal engineering road bridge crack repair fixed structure. Utility Model Content

Then the staff can pour cement into the pit. At this time, the extension rod is used to play the role of barb, which significantly increases the contact area between the steel bar, the fixing rod, the extension rod and the cement, thereby improving the structural strength of the subsequent high pit filling.

[0013] 2. The utility model can vibrate the cavity after pouring cement so that the cement can flow into the interior of the fixing rod, thereby further improving the installation stability of the support mechanism. BRIEF DESCRIPTION OF THE DRAWINGS
