Description

Technical Field

[0001] The utility model relates to the technical field of scour-resistant bridge pile foundation structures, in particular to an scour-resistant bridge pile foundation structure. Background Art

[0002] A bridge generally refers to a structure built across rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. To adapt to the modern high-speed development of the transportation industry, bridges are also extended to refer to buildings that cross mountain streams, poor geology, or meet other transportation needs to make travel more convenient. Bridges are generally composed of superstructure, substructure, supports, and ancillary structures. The superstructure, also known as the span structure, is the main structure for crossing obstacles. The substructure includes abutments, piers, and foundations. The supports are force transmission devices installed at the supporting locations of the span structure and piers or abutments. Ancillary structures refer to the bridgehead slabs, conical slope protection, bank protection, and diversion projects.

[0003] Bridge pile foundations are the most important foundation type in bridge engineering. Since they are fixed at the bottom of the riverbed all year round, they will always be affected by water flow. Long-term scouring will reduce the stability of the pile foundation and cause the position of the pile foundation to shift, which will lead to bridge damage or cause bridge safety hazards.

[0004] To this end, we provide an anti-scouring bridge pile foundation structure to solve the above problems. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 - Figure 4 As shown, the utility model provides a technical solution: an anti-scour bridge pile foundation structure, including a base 1, the outer surface of the base 1 is fixedly connected with four connecting blocks 2, the inner wall of each connecting block 2 is rotatably connected with a screw 5, the outer surface of each screw 5 is rotatably connected with the base 1, and each screw 5 is fixedly connected with a bevel gear 7 at one end away from the corresponding connecting block 2, and each bevel gear 7 is meshed with an adjacent bevel gear 7, and the upper surface of each connecting block 2 is fixedly connected with a stopper 8, and the upper surface of the base 1 is provided with four slide grooves 4, and the inner wall of each slide groove 4 is slidably connected with a first push block 6, and each first The push blocks 6 are all threadedly connected with the corresponding screw rods 5. Specifically, the four bevel gears 7 have the same specifications and are evenly arranged inside the base 1. The four bevel gears 7 are engaged with each other so that the four bevel gears 7 can rotate at the same time, and thereby drive the corresponding screw rods 5 to rotate at the same time. The rotation of the screw rods 5 will drive the corresponding first push block 6 to move horizontally along the corresponding screw rods 5. At this time, the first push block 6 will simultaneously move along the corresponding slide groove 4 toward the axis center of the base 1 or move horizontally away from the axis center of the base 1. The connecting block 2 is fixed to the outside of the corresponding slide groove 4, and the position of the first push block 6 is constrained by the stop block 8.

[0026] like Figure 2 , Figure 3As shown, a pile foundation column 11 is fixedly connected to the upper surface of the base 1, a fixing ring 10 is slidably connected to the outer surface of the pile foundation column 11, and eight second push blocks 17 are fixedly connected to the outer surface of the fixing ring 10. The fixing ring 10 can slide vertically on the pile foundation column 11, and can support the pile foundation column 11. According to the height of the fixing ring 10, the pile foundation column 11 can be more stably supported and fixed. The second push blocks 17 are divided into two layers, and each layer has four second push blocks 17, which are evenly distributed on the outer surface of the fixing ring 10.

[0027] like Figure 2 , Figure 3 As shown, the inner wall of each first push block 6 is rotatably connected to the first support plate 9, and the outer surface of each first support plate 9 is rotatably connected to the corresponding second push block 17. Specifically, when the first push block 6 moves horizontally, the corresponding first support plate 9 will push the fixing ring 10 to move vertically upward along the pile foundation column 11, and then the fixing ring 10 can be supported by the first support plate 9 to prevent the pile foundation column 11 from shifting.

[0028] like Figure 2 As shown, a fixing plate 13 is fixedly connected to the outer surface of the pile foundation column 11 , and four T-slots 14 are formed on the bottom surface of the fixing plate 13 . The T-slots 14 are evenly formed on the bottom surface of the fixing plate 13 .

[0029] like Figure 1 , Figure 2 As shown, the inner wall of each T-slot 14 is slidably connected to a third push block 16, and the inner wall of each third push block 16 is rotatably connected to a second support plate 12. The second support plate 12 can rotate around the corresponding third push block 16, and the third push block 16 can slide horizontally along the corresponding T-slot 14.

The side of each baffle 15 close to the fixed disk 13 is fixedly connected to the fixed disk 13. The second support plate 12 can rotate around the corresponding second push block 17. The connection between the second support plate 12 and the second push block 17 and the third push block 16 enables the fixing ring 10 to support the fixing disk 13 through the second support plate 12. During the vertical upward movement of the fixing ring 10, the second support plate 12 will push the corresponding third push block 16 to slide horizontally along the corresponding T-slot 14 until the third push block 16 is squeezed and contacted with the corresponding baffle 15, thereby increasing the stability of the fixing ring 10 and performing secondary reinforcement on the pile foundation column 11.

[0031] like Figure 1 , Figure 2 , Figure 3As shown, a motor 3 is fixedly mounted on the outer surface of one of the connection blocks 2, and the output end of the motor 3 is fixedly connected to the corresponding screw 5. When the motor 3 is started, it will drive the corresponding screw 5 to rotate, and through the mutual engagement of the bevel gears 7, it will drive the four screws 5 to rotate simultaneously.

[0032] Working principle: First, start the motor 3, which will drive the corresponding screw rod 5 to rotate. The four screw rods 5 will rotate simultaneously through the mutual engagement of the bevel gears 7. The rotation of the screw rod 5 will drive the corresponding first push block 6 to move along the corresponding slide groove 4 toward the axis of the base 1. At this time, the first push block 6 will push the corresponding first support plate 9 to squeeze and support the fixing ring 10, and then the fixing ring 10 will slowly move vertically upward along the pile foundation column 11. Then, the fixing ring 10 will push the corresponding second support plate 12 through the second push block 17 to push the third push block 16, and make it move horizontally away from the axis direction of the fixed disk 13 along the corresponding T-slot 14, until the second push block 17 is squeezed and contacted with the corresponding baffle plate 15 to stop the start of the motor 3. At this time, the first support plate 9 and the second support plate 12 will support the fixing ring 10. At the same time, the support and fixation of the fixing ring 10 will stably support and fix the pile foundation column 11.
