Abstract
Description
Technical Field
[0001] This application relates to the field of highway bridge pile foundation technology, and in particular to a reinforcement device for highway bridge pile foundations. Background Technology
[0002] Highway bridge pile foundations refer to deep foundations consisting of piles and pile caps (or simply pile caps) connecting the tops of the piles, or single pile foundations consisting of columns connected to the pile foundations. If the entire pile body is buried in the soil and the bottom surface of the pile cap is in contact with the soil, it is called a low pile cap pile foundation. If the upper part of the pile body is exposed above the ground and the bottom of the pile cap is above the ground, it is called a high pile cap pile foundation. With the increase in traffic volume and the increase in heavy vehicles, the bearing capacity of bridge pile foundations may not be able to meet the current needs.
[0003] The common practice is to reinforce the pile foundation to improve its bearing capacity and ensure the safe operation of the bridge under heavy loads. Existing reinforcement devices for highway bridge pile foundations are usually integral structures, which are inconvenient to disassemble and repair when damaged, resulting in low work efficiency. Therefore, we provide a reinforcement device for highway bridge pile foundations. Utility Model Content
[0004] The purpose of this invention is to provide a reinforcement device for highway bridge pile foundations to solve the problems mentioned in the background art.
[0005] The embodiments of this application adopt the following technical solutions:
[0006] A reinforcement device for highway bridge pile foundations includes a first reinforcement seat, a second reinforcement seat, and a pile foundation. The upper surface of the first reinforcement seat has symmetrical first grooves. Each of the two first grooves is hinged with a locking plate via a pin. Each of the two first grooves is connected to a spring, the top of which is connected to the bottom surface of the locking plate. The upper surface of the second reinforcement seat has symmetrical second grooves. Each of the two second grooves is connected to a locking block, and each locking plate contacts the locking block. The right side of the first reinforcement seat has symmetrical insertion openings, and the left side of the second reinforcement seat has symmetrical insertion blocks, both of which are adapted to the insertion openings. The upper surfaces of both the first and second reinforcement seats have sliding grooves. Each of the two sliding grooves has a sliding block slidably connected to a slider. The outer surface of each slider has an adjusting component. The upper surface of each slider is connected to a support rod. The top of each support rod is connected to a fixing block. A reinforcement plate is connected to the side of each fixing block that is close to each other. The pile foundation is located between the two reinforcement plates.
[0007] Preferably, both adjustment components include bearings, and bearings are embedded in the opposite sides of the two sliders. Threaded rods are threaded into the interiors of both the first and second reinforcement seats, and the ends of the two threaded rods that are close to each other are connected to the inner ring of the bearings.
[0008] Preferably, the upper surfaces of the first and second reinforcement bases are provided with symmetrical mounting holes, and ground nails are movably connected inside the two sets of mounting holes.
[0009] Preferably, the inner walls of both sliding grooves are provided with symmetrical limiting grooves, and the interiors of both sets of limiting grooves are slidably connected with limiting blocks. The sides of the two sets of limiting blocks that are close to each other are connected to the outer surface of the slider.
[0010] Preferably, the outer surfaces of the two reinforcing plates are connected to symmetrical lugs, the two sets of lugs are provided with bolts inside, the outer surfaces of the two bolts are threaded with nuts, and the left side of the two nuts is in contact with the right side of one set of lugs.
[0011] Preferably, the two reinforcing plates are each connected to a protective pad on their adjacent sides, and the adjacent sides of the two protective pads are in contact with the outer surface of the pile foundation.
[0012] Preferably, the bottom surfaces of both card plates are provided with a first chamfer, and the outer surfaces of both card blocks are provided with symmetrical second chamfers.
[0013] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects:
[0014] During the process of merging the first and second reinforcing seats, the locking block will lift the locking plate, causing one end of the locking plate to move upward and the other end of the locking plate to move downward and compress the spring. When one end of the locking plate passes through the locking block and enters the second groove, the spring will use its own elasticity to drive the other end of the locking plate to automatically reset, so that the locking plate and the locking block are interlocked to prevent the two reinforcing seats from separating from left to right. At the same time, the insert will be inserted into the socket to prevent the two reinforcing seats from separating vertically, thus completing the installation. The split design of this device can improve the work efficiency during maintenance. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0022] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.
[0023] Please see Figure 1-4 This utility model provides a technical solution for a reinforcement device for highway bridge pile foundations:
[0024] A reinforcement device for highway bridge pile foundations includes a first reinforcement base 1, a second reinforcement base 2, and a pile foundation 3. The upper surface of the first reinforcement base 1 has symmetrical first grooves 9. Each of the two first grooves 9 is hinged to a locking plate 11 via a pin. Each of the two first grooves 9 is connected to a spring 8, the top of which is connected to the bottom surface of the locking plate 11. The upper surface of the second reinforcement base 2 has symmetrical second grooves 10. Each of the two second grooves 10 is connected to a locking block 26, and each of the two locking plates 11 contacts the locking block 26. The right side of the first reinforcement base 1 has symmetrical insertion slots 19, and the left side of the second reinforcement base 2 has symmetrical insertion blocks 20, both of which are adapted to the insertion slots 19. The upper surfaces of both the first reinforcement base 1 and the second reinforcement base 2 have sliding grooves 14. Each of the two sliding grooves 14 has a sliding block 16 slidably connected inside, and the outer surface of each sliding block 16 has an adjustment mechanism. In component 17, support rods 21 are connected to the upper surfaces of the two sliders 16, and fixing blocks 22 are connected to the tops of the two support rods 21. Reinforcing plates 23 are connected to the sides of the two fixing blocks 22 that are close to each other. The pile foundation 3 is located between the two reinforcing plates 23. Specifically, the locking plate 11 and the locking block 26 can be locked together to position the first reinforcing seat 1 and the second reinforcing seat 2. The spring 8 can automatically reset the locking plate 11 and position it. The first groove 9 and the pin can be engaged to allow the locking plate 11 to swing left and right. The insertion block 20 can be inserted into the insertion port 19 to prevent the first reinforcing seat 1 and the second reinforcing seat 2 from separating vertically. The sliding groove 14 can limit the movement range of the slider 16. By adjusting component 17 to move the slider 16, the reinforcing plate 23 can clamp the pile foundation 3, thereby reinforcing the pile foundation 3.
[0025] In this embodiment, both adjusting components 17 include bearings 172, and bearings 172 are embedded in the opposite sides of the two sliders 16. Threaded rods 171 are threadedly connected to the interiors of the first reinforcing seat 1 and the second reinforcing seat 2. The ends of the two threaded rods 171 that are close to each other are connected to the inner rings of the bearings 172. Symmetrical mounting holes 15 are provided on the upper surfaces of the first and second reinforcing seats 1 and 2. Ground nails 7 are movably connected inside the two sets of mounting holes 15. Symmetrical limiting grooves 25 are provided on the inner walls of the two sliding grooves 14. Both sets of limit blocks 18 are slidably connected, and the sides of the two sets of limit blocks 18 that are close to each other are connected to the outer surface of the slider 16. Specifically, the threaded rod 171 rotates inside the first reinforcement seat 1 and the second reinforcement seat 2. The threaded rod 171 can drive the slider 16 to move and position it through the bearing 172. The ground nail 7 is inserted into the ground through the mounting hole 15 and can position the first reinforcement seat 1 and the second reinforcement seat 2. The limit block 18 slides with the slider 16 in the limit groove 25 and can position the slider 16 to prevent the slider 16 from falling out of the groove 14.
[0026] In this embodiment, the outer surfaces of the two reinforcing plates 23 are connected to symmetrical lugs 4. Bolts 5 are provided inside both sets of lugs 4. Nuts 6 are threaded onto the outer surfaces of the two bolts 5. The left side of each nut 6 contacts the right side of one set of lugs 4. Protective pads 24 are connected to the sides of the two reinforcing plates 23 that are close to each other. The sides of the two protective pads 24 that are close to each other contact the outer surface of the pile foundation 3. A first chamfer 12 is provided on the bottom surface of both clamping plates 11, and a symmetrical second chamfer 13 is provided on the outer surface of both clamping blocks 26. Specifically, by inserting the bolts 5 into the lugs 4 and then installing the nuts 6 onto the bolts 5, the two reinforcing plates 23 can be reinforced. The two protective pads 24 are made of rubber, which prevents the reinforcing plates 23 from directly contacting the pile foundation 3 and causing damage. The first chamfer 12 and the second chamfer 13 reduce the friction between the clamping plates 11 and the clamping blocks 26, making it easier for the clamping blocks 26 to lift the clamping plates 11.
[0027] Working principle: When using this device, the user first moves the first reinforcing seat 1 and the second reinforcing seat 2 relative to each other to merge, causing the locking block 26 to lift the locking plate 11, causing one end of the locking plate 11 to move upward, while the other end of the locking plate 11 moves downward and squeezes the spring 8. When one end of the locking plate 11 passes the locking block 26 and enters the second groove 10, the spring 8 will use its own elasticity to drive the other end of the locking plate 11 to automatically reset, so that the locking plate 11 and the locking block 26 are locked together, preventing the first reinforcing seat 1 and the second reinforcing seat 2 from separating left and right. At the same time, the insert block 20 will be inserted into the insertion port 19 to prevent the first reinforcing seat 1 and the second reinforcing seat 2 from separating up and down, thus completing the installation. Rotating the two threaded rods 171, both threaded rods 171 drive the two sliders 16 to move relative to each other through the bearing 172, causing the two support rods 21 to drive the two reinforcing plates 23 to move relative to each other through the fixing block 22 to reinforce the pile foundation 3.
[0028] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
