Description

Technical Field

[0001] The utility model relates to the technical field of road crack repair, in particular to a shallow crack locator used in the process of road and bridge construction. Background Art

[0002] Cracks are one of the most common forms of damage to bridge structures. Their existence will lead to a reduction in the load-bearing capacity of the bridge, accelerate fatigue damage of the structure, increase the unsafety of vehicle driving, and also affect the appearance of the bridge. Therefore, cracks need to be repaired.

[0003] At present, the method of crack repair is generally to pour cement mortar into the cracks so that the mortar fills the gaps and completes the crack repair. However, during the repair process, the mortar cannot be accurately flowed into the gaps, and a large amount of mortar will flow to the ground, resulting in a waste of mortar. In view of this, we propose a shallow crack locator for road and bridge construction. Utility Model Content

[0014] The utility model provides a shallow crack locator used in the process of road and bridge construction. It has the following beneficial effects:

[0015] (1) The shallow crack locator used in the construction process of roads and bridges can adjust the distance between the inclined plates 1 and 2 through the design of the slide seat 1, the slide seat 2 and the bidirectional screw. When the distance between the inclined plates 1 and 2 is slightly larger than the width of the gap, mortar is poured in, wherein the inclined plates 1 and 2 will limit the mortar to prevent the mortar from flowing onto the ground, thereby improving the utilization rate of the mortar and achieving the purpose of saving mortar.

[0016] (2) The shallow crack locator used in the process of road and bridge construction, after the mortar is poured in, pull the cross bar, so that the cross bar pulls the scraper 1 and the scraper 2 to move, thereby scraping the mud flat, so that the mud flows into the crack along the inclined plate 1 and the inclined plate 2, thereby completing the crack repair and improving the efficiency of crack repair. At the same time, through the hinged design between the scraper 1 and the scraper 2, the scraper 1 and the scraper 2 can be used for cracks of different widths, thereby improving their applicability.
