Description

Technical Field

[0001] This utility model relates to the field of bridge reinforcement technology, specifically a bridge foundation reinforcement structure. Background Technology

[0002] The portion of the soil that bears the load transmitted from the foundation is called the subgrade. When the subgrade and foundation are subjected to various loads, they will generate stress and deformation. In order to ensure the normal use and safety of the bridge, the subgrade and foundation must have sufficient strength and stability, and the deformation should be within the allowable range.

[0003] Existing bridge structures suffer from foundation erosion due to water flow, natural corrosion, and other factors, resulting in hollowing at the bottom of the foundation, softening of the soil, and damage to pine or cement piles. These combined factors reduce the bearing capacity of the original bridge foundation, making it unable to meet the requirements for continued operation.

[0004] Therefore, this utility model provides a bridge foundation reinforcement structure to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a bridge foundation reinforcement structure, such as Figure 1-5 As shown, the bridge foundation reinforcement structure includes a bridge foundation body 1. A first ring sleeve 5 is fixedly sleeved on the outer wall of the bridge foundation body 1. Multiple sets of support rods 6 are installed in a ring on the first ring sleeve 5. A second ring sleeve 7 is sleeved on the lower end of the bridge foundation body 1. A first connecting rod 8 is rotatably installed at the connection between the first ring sleeve 5 and the multiple sets of support rods 6. Multiple sets of second connecting rods 9 are installed in a ring on the second ring sleeve 7. A third connecting rod 10 is rotatably installed inside each of the multiple sets of support rods 6. The multiple sets of first connecting rods 8, multiple sets of second connecting rods 9 and multiple sets of third connecting rods 10 are interconnected. A protective sleeve 11 is fixedly installed on the upper end of the first ring sleeve 5. Fastening components for reinforcing the connection between the second ring sleeve 7 and the protective sleeve 11 and the bridge foundation body 1 are provided on the second ring sleeve 7 and the protective sleeve 11.

[0025] The first ring 5, multiple sets of support rods 6, the second ring 7, multiple sets of first connecting rods 8, multiple sets of second connecting rods 9, and multiple sets of third connecting rods 10 work together to form a stable support system. Through the cooperation of the fastening components, the load-bearing capacity and stability of the reinforced structure can be further enhanced.

[0026] The lower end of the bridge foundation body 1 is provided with a first concrete reinforcing pile 3, and the upper end of the first concrete reinforcing pile 3 is provided with a second concrete reinforcing pile 4. Multiple sets of support rods 6 are located inside the first concrete reinforcing pile 3 and the second concrete reinforcing pile 4.

[0027] This makes the multiple sets of support rods 6 more stable during installation and use, and less prone to shaking or falling off, thereby improving the stability and reliability of the entire reinforcement structure. At the same time, the trapezoidal arrangement of the first concrete reinforcing pile 3 and the second concrete reinforcing pile 4 can effectively distribute external loads and further enhance the load-bearing capacity of the reinforcement structure.

[0028] A reinforcing cage 2 is installed on the lower outer wall of the bridge foundation body 1, and multiple sets of reinforcing cages 2 are located inside the first concrete reinforcing pile 3 and the second concrete reinforcing pile 4.

[0029] By increasing the pouring of the reinforcing cage 2 to form the first concrete reinforcing pile 3 and the second concrete reinforcing pile 4, the reinforcement and bearing capacity of the first concrete reinforcing pile 3 and the second concrete reinforcing pile 4 are improved.

[0030] The fastening assembly includes multiple sets of fixing plates 12, which are respectively fixedly installed on the outer walls of the second ring sleeve 7 and the protective sleeve 11. Multiple sets of reinforcing rods 13 are movably installed between the multiple sets of fixing plates 12 of the second ring sleeve 7 and the protective sleeve 11. Each set of reinforcing rods 13 is threaded with a first nut 14. Each set of fixing plates 12 is fixedly installed with a reinforcing plate 15. Each set of fixing plates 12 and the multiple sets of reinforcing plates 15 is threaded with a vertical rod 16. Each set of vertical rods 16 is movably installed with a ball shaft 17. Reinforcing rods 18 are inserted into the upper and lower ends of the bridge foundation body 1. Each set of reinforcing rods 18 is threaded with a second nut 19. The opposite ends of the multiple sets of reinforcing rods 18 inserted into the bridge foundation body 1 are respectively inserted into the ball shafts 17 on the multiple sets of vertical rods 16.

[0031] Through the mutual connection of multiple sets of fixing plates 12, multiple sets of reinforcing rods 13, multiple sets of first nuts 14, multiple sets of reinforcing plates 15, multiple sets of uprights 16 and multiple sets of ball shafts 17, a stable connection structure is formed, thereby enhancing the stability and load-bearing capacity of the entire reinforcement structure. At the same time, the setting and insertion of reinforcing rods 18 into the bridge foundation body 1 can further increase the integrity and stability of the reinforcement structure and prevent deformation or damage during use.

[0032] The first concrete reinforcing pile 3 and the second concrete reinforcing pile 4 have trapezoidal cross-sections, and the diameter of the second concrete reinforcing pile 4 is smaller than the diameter of the first concrete reinforcing pile 3.

[0033] The first concrete reinforcing pile 3 and the second concrete reinforcing pile 4 are arranged in a trapezoidal pattern, which can improve the stability and bearing capacity of the lower end of the bridge foundation body 1 in the soil.

[0034] When multiple sets of first connecting rods 8, multiple sets of second connecting rods 9, and multiple sets of third connecting rods 10 are connected, they are all arranged in a three-pronged shape. The connection points of multiple sets of first connecting rods 8, multiple sets of second connecting rods 9, and multiple sets of third connecting rods 10 are all located on the opposite side of multiple sets of support rods 6.

[0035] When multiple sets of first connecting rods 8, multiple sets of second connecting rods 9, and multiple sets of third connecting rods 10 are connected, they are all arranged in a three-pronged shape. This three-pronged connection structure can form a more stable support point, enhance the resistance of multiple sets of support rods 6 to external loads, and improve the stability and safety of the overall structure.

[0036] Working principle: When reinforcing the bridge foundation body 1, the first ring sleeve 5 and the second ring sleeve 7 are fixed to the outer wall of the bridge foundation body 1. Multiple sets of support rods 6 are rotated open on the support rods 6, and then multiple sets of first connecting rods 8, multiple sets of second connecting rods 9 and multiple sets of third connecting rods 10 are connected to each other, thereby supporting and fixing the multiple sets of support rods 6 after they are unfolded. Multiple sets of reinforcing rods 13 are movably inserted into multiple sets of fixing plates 12 on the second ring sleeve 7 and the protective sleeve 11, and multiple sets of first nuts 14 are used to tighten the reinforcing rods 13 inserted into the multiple sets of fixing plates 12 on the second ring sleeve 7 and the protective sleeve 11. Both ends are locked and fixed. Multiple sets of reinforcing rods 18 are inserted into the ball shafts 17 on multiple sets of uprights 16, and the multiple sets of reinforcing rods 18 are rotatably inserted into the bridge foundation body 1. Multiple sets of reinforcing plates 15 are fixed on multiple sets of reinforcing rods 13, and multiple sets of uprights 16 are respectively locked and connected to multiple sets of fixing plates 12 and multiple sets of reinforcing plates 15, thereby forming an integral reinforcement structure, making the reinforcement structure more stable and reliable during use. The lower end of the bridge foundation body 1 is woven into a reinforcing cage 2, so that the concrete pouring forms the first concrete reinforcing pile 3 and the second concrete reinforcing pile 4 through the reinforcing cage 2.
