Description

Technical Field

[0001] The invention relates to the field of road bridge crack repair, and in particular to a road bridge crack repair fixing structure. Background Art

[0002] Repairing road and bridge cracks is a complex and important engineering process. In the early stage, it is necessary to accurately measure the width, length and depth of the cracks to determine the nature of the cracks, evaluate the impact of the cracks on the safety of the road and bridge structure, and remove debris, dust and oil stains on the surface of the cracks. The cracks must be polished and cleaned as necessary so that the repair materials can adhere better. Finally, the repair method should be selected according to the actual situation to achieve the effect of road repair.

[0003] The Chinese invention patent application with the announcement number CN114214973B discloses a road bridge crack repair fixing structure, comprising a horizontally arranged receiving plate, the lower surface of which is horizontally slidably connected to two tightening plates, the two ends of which are vertically slidably penetrated by receiving columns, the ends of the two tightening plates which are far from each other are respectively provided with receiving grooves for the corresponding receiving columns to be inserted, and a locking piece is arranged between the two tightening plates, which is used to fix the two tightening plates. By tightening the two sides of the crack with two tightening plates, this design can reduce the risk of concrete cracking compared to simply filling with concrete, thereby reducing the risk of gradual expansion of cracks in roads and bridges, and thus improving the repair effect of roads and bridges.

[0004] After the existing road bridge pavement cracks, a fixed structure is generally installed at the crack and then the inside is filled, so that the repaired crack maintains a high strength to meet the road surface strength requirements. However, the existing fixed structure is generally connected to the road bridge pavement by ground nails. This method is prone to loosening during later use, thereby affecting the stability of the fixed structure, and the secondary repair needs to be re-fixed, which causes certain damage to the facade. In addition, since the gaps at the gaps are large and small, the ground nail fixation method cannot guarantee the fixing strength at larger gaps, so that it can only meet the repair work of smaller gaps. In addition, since the road surface will expand and contract when it is warm in winter and cool in summer, the bridge pavement is generally provided with a buffer gap. However, if the repaired road surface is under this premise, it is easy to cause the risk of fracture of the concrete layer and the fixed structure poured at the repair site, thereby affecting the safety of use inside.

[0054] like Figure 1-9As shown, according to the specific size of the gap in the road bridge pavement, a road surface cutting machine is used to open the embedded groove 101, the embedded groove 2 102, the clamping groove 103 and the connecting groove 104, and at the same time, the docking rod 206, the fixing rod 204 and the fixed hollow tube 201 of corresponding sizes are prefabricated according to the needs. At this time, the docking rod 206 and the fixing rod 204 are docked, and the two are passed through the interior of the fixed hollow tube 201. At the same time, the threaded sleeve 309 is used to fix the fixing rod 204, and the fixed hollow tube 201 and the connecting hollow tube 302 are docked and fixed. At this time, the connecting hollow tube 302 is fixed in the crack through the fixing frame 301, and the fixing frame 301 can be selectively installed according to the actual situation. At the same time, the fixed hollow tube 201 and the clamping plate 1 203 are docked and then clamped into the corresponding embedded groove 101, embedded groove 2 102, clamping groove 103 and connecting groove 104. At this time, the embedded groove 101, the embedded groove 2 102 and the road surface are backfilled and poured, and the nut 305 is rotated at the same time, so that the nut 305 drives the bevel gear 1 306 under the rotating shaft 304 to rotate, so that the screw 307 drives the threaded sleeve 309 to move, so that the fixed rod 204 drives the docking rod 206 to slide in the fixed hollow tube 201, so that the clamping plate 209 and the clamping groove 103 are in contact with each other, so that the road surfaces on both sides of the gap are mutually stressed, and finally the protective plate 105 is installed and covered on the road surface through the expansion bolts, thereby completing the road surface repair work. Through this method of structural pouring and backfilling, a stable fit between the fixed structure and the road surface can be ensured to avoid looseness, and this method can be customized according to the size of the gap, so that cracks of different gap sizes can be effectively repaired. Finally, this method can adjust the force of the fixed structure according to the seasonal changes in the later period, so as to ensure the strength of the overall structure.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
