Technical Field

[0001] This utility model relates to the field of building bridge technology, specifically a bridge and wharf underwater pile foundation reinforcement device with multi-angle repair function. Background Technology

[0002] The underwater pile foundation reinforcement device for bridges and wharves is an engineering device specifically designed to repair, enhance, or protect the stability and bearing capacity of underwater pile foundation structures. It is mainly used to address damage to pile foundations caused by corrosion, erosion, cracks, or load changes.

[0003] However, in the existing technology, most of the reinforcement of underwater pile foundations adopts the method of wrapping the outside with a steel sleeve. Since the pile foundation is corroded and the surface is uneven, simply wrapping with a steel sleeve results in a general reinforcement effect and cannot reinforce the uneven surface of the pile foundation from multiple angles. Therefore, a bridge and wharf underwater pile foundation reinforcement device with multi-angle repair function is proposed. Summary of the Invention

[0004] The purpose of this utility model is to provide a bridge and wharf underwater pile foundation reinforcement device with multi-angle repair function.

Multiple reinforcing bolts 7 are set to compress the flexible steel plate 8 and fully fit the uneven outer arc surface of the concrete pile 1 inside the flexible steel plate 8. Because the flexible steel plate 8 is a flexible steel plate, when the worker tightens the reinforcing bolts 7 with tools, the ends of the reinforcing bolts 7 rotate within the connecting seats. The reinforcing bolts 7 are threadedly connected to the outer arc surfaces of the first reinforcing cover 3, the second reinforcing cover 4, the third reinforcing cover 5, and the fourth reinforcing cover 6, respectively. When the worker tightens the reinforcing bolts 7, the flexible steel plate 8 fits against the outer arc surface of the concrete pile 1, and the concrete pile 1 is reinforced and supported by the flexible steel plate 8.

[0031] The reinforcement component includes a lower insertion block 2. The bottom ends of the first reinforcement cover 3 and the second reinforcement cover 4 are respectively provided with the lower insertion block 2. The inner wall of the lower insertion block 2 is in contact with the outer arc surface of the concrete pile 1. The lower insertion block 2 is also provided at the bottom ends of the first reinforcement cover 3 and the second reinforcement cover 4. The inner wall of the lower insertion block 2 is in contact with the outer arc surface of the bottom end of the concrete pile 1. This allows the workers to fully insert the lower insertion block 2 into the soil at the bottom end of the concrete pile 1 below the water surface when installing the first reinforcement cover 3 and the second reinforcement cover 4, thereby positioning the first reinforcement cover 3 and the second reinforcement cover 4.

[0032] The top surface of the first reinforcement cover 3, the second reinforcement cover 4, the third reinforcement cover 5 and the fourth reinforcement cover 6 are all provided with an injection port 10.

[0034] The side walls of the first reinforcing cover 3 and the third reinforcing cover 5 are provided with inserts 12 on the outside of the semi-injection cavity 16, and slots 11 are provided on the inside of the semi-injection cavity 16. The side walls of the second reinforcing cover 4 and the fourth reinforcing cover 6 are respectively inserted into the slots 11 and inserts 12 on the side walls of the first reinforcing cover 3 and the third reinforcing cover 5.

[0035] The bottom surfaces of the third reinforcing cover 5 and the fourth reinforcing cover 6 are provided with inserts 14 corresponding to the injection port 10. The inserts 14 are inserted into the inside of the injection port 10 and contact the inner bottom surface of the injection cavity 9.

[0036] The reinforcement assembly still includes an outer reinforcement plate 13. The sidewalls of the first reinforcement cover 3, the second reinforcement cover 4, the third reinforcement cover 5 and the fourth reinforcement cover 6 that are in contact with each other are all fixedly installed with the outer reinforcement plate 13. The outer reinforcement plate 13 that is in contact with the first reinforcement cover 3 and the second reinforcement cover 4 and the third reinforcement cover 5 and the fourth reinforcement cover 6 is fixedly installed with bolts.

[0037] Finally, a grouting port 10 is provided in the middle of the top surface of the first reinforcing cover 3, the second reinforcing cover 4, the third reinforcing cover 5, and the fourth reinforcing cover 6. Below the grouting port 10, grouting cavities 9 are provided inside the first reinforcing cover 3, the second reinforcing cover 4, the third reinforcing cover 5, and the fourth reinforcing cover 6. This allows workers to attach the first reinforcing cover 3 and the second reinforcing cover 4 to the outside of the concrete pile 1. After fixing the outer reinforcing plates 13 on the outer arc surfaces of the first reinforcing cover 3 and the second reinforcing cover 4 with bolts, concrete is poured into the grouting cavities 9 through the grouting port 10. After pouring, concrete is then poured into the first reinforcing cover 3 and the second reinforcing cover 4. Concrete is poured into the cavity formed by the second reinforcement cover 4 to increase the need for reinforcement and repair of the concrete pile 1. After the first reinforcement cover 3 and the second reinforcement cover 4 are installed, the inserts 14 on the bottom surface of the third reinforcement cover 5 and the fourth reinforcement cover 6 are inserted into the concrete inside the grouting port 10. The third reinforcement cover 5 and the fourth reinforcement cover 6 are installed and fixed in the same way. Similarly, underwater non-dispersible concrete grout and underwater non-dispersible epoxy grout are poured into the grouting cavity 9 inside the third reinforcement cover 5 and the fourth reinforcement cover 6 to reinforce and repair the concrete pile 1 and increase the service life of the concrete pile 1.
