[0002] The steel casing structure for road and bridge pile foundation reinforcement is an auxiliary structure used to enhance the stability of bridge and road pile foundations. It is usually made of high-strength steel and has good thickness and rigidity. It mainly consists of a steel casing bottom plate installed at the bottom of the steel casing to prevent grout leakage during concrete pouring. Some sealing systems also include a stop valve, which is set in the bottom concrete pipe connector to control the concrete pouring.

[0003] In related technologies, when steel casings are used to reinforce road and bridge pile foundations, construction workers usually need to continuously observe the position of the steel casings for alignment. However, this can lead to errors in the alignment of the steel casings, requiring construction workers to adjust the position multiple times, which reduces construction efficiency. Summary of the Invention

[0015] A steel casing structure and construction method for reinforcing road and bridge pile foundations includes the following steps: S1. When a steel casing body is placed and docked with a second steel casing body, the electric push rod is activated to push the locking block to clamp and fix the first steel casing body to prevent displacement. At this time, the electric push rod is activated to drive the guide rail to rise and fall, and the fixing block will drive the installation component to slide on the outer wall of the second steel casing body. After moving to the appropriate position, it will lock the second steel casing body. The fixing block and the installation component will be rotated again so that the first and second steel casing bodies can be positioned and installed. S2. Start the electric push rod two to push the guide block to move, so that the guide block drives the clamping block two to clamp the steel casing body through the adjustment component. Start the electric push rod three to pull the guide rail to slide, so that the installation component and the clamping block two drive the second steel casing body to slide down and connect. When the guide block moves to the appropriate position, the push plate will push the opening and closing plate to close, and let the magnetic block one push out and attract the magnetic block two. So that when the guide block is pulled back, it drives the magnetic block two and the installation component to move synchronously, thus facilitating the connection of the two sets of steel casing bodies. The clamping block two will continue to clamp the second steel casing body. S3. When magnetic block two moves, it will drive the right-angle block and the tilting push block to rotate synchronously, thereby allowing the tilting push block to push the baffle to move. This opens the storage box to facilitate bolt discharge. When the guide block moves to the appropriate position, the push plate will push the opening and closing plate to open. At this time, elastic element two will push the top block and connecting column to move, causing magnetic block one to disengage from magnetic block two and quickly reset through elastic element three. At the same time, magnetic block two will push the right-angle block to rotate and compress elastic element four. At this time, the tilting push block will push the baffle to close the storage box. At this time, the control assembly will tighten the bolts, thereby allowing the bolts to connect with the two sets of steel casing bodies. S4. When the bolts are turned, the positioning column will slide, causing the positioning column to push the inclined support plate to raise the support column and connect with the two sets of steel casing bodies. At the same time, the inclined support plate will cooperate with the rotating rod and the adjusting rod to make the clamping plate clamp the two sets of steel casing bodies so that they fit tightly together.

[0016] This invention provides a steel casing structure and construction method for reinforcing road and bridge pile foundations. It has the following beneficial effects: 1. This invention uses an electric push rod to push a clamping block to hold the steel casing body. The electric push rod also controls the guide rail to rise and fall. The position is adjusted by the fixed block sliding on the inner wall of the guide rail. At this time, the electric push rod is activated to push the guide block and the adjusting block to move synchronously, so that the clamping block holds the steel casing body. The clamping blocks 1 and 2 can quickly fix two sets of steel casing bodies and can quickly adjust the position of one set, achieving precise docking, reducing errors, and improving construction efficiency.

[0017] 2. In this invention, the top block and the second elastic element work together to lift the guide column, causing the toothed plate to disengage from the toothed column, thereby allowing the adjusting block to slide. At the same time, the top block pushes and pulls the connecting column, causing the tilting block to push and pull the first magnetic block, thereby allowing the first magnetic block to attract the second magnetic block and allowing the installation component to slide. The top block can quickly clamp the steel casing body to prevent displacement when rotating the steel casing body.

[0018] 3. In this invention, the magnetic block 2 pushes the right-angle block to rotate, and the elastic element 4 also pushes the right-angle block, thereby causing the inclined pusher to push the baffle to slide and open the storage box to allow the thread to enter. When the magnetic block 2 resets, it will cause the right-angle block to rotate and compress the elastic element 4, thereby causing the baffle to close the storage box. The right-angle block can accurately cut materials and install bolts, thus shortening the bolt installation time.

[0019] 4. In this invention, the positioning column is pushed by bolts to allow the inclined support plate to slide, thereby raising the support column to connect with the two sets of steel casing bodies. At the same time, the inclined support plate, together with the rotating rod and the adjusting rod, allows the snap-fit ​​plate to slide synchronously. The snap-fit ​​plate will lock the two sets of steel casing bodies. The snap-fit ​​plate can improve the strength of the two sets of steel casing bodies, thereby improving the reinforcement quality of the steel casing bodies. Attached Figure Description

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1: Please see the appendix Figure 1 - Appendix Figure 4This invention provides a steel casing structure for reinforcing road and bridge pile foundations, including a base plate 1. Multiple sets of mounting blocks 2 are fixedly connected to the lower surface of the base plate 1. An electric push rod 3 is fixedly connected to the inner wall of each mounting block 2. A locking block 4 is fixedly installed at the output end of the electric push rod 3. An electric push rod 6 is fixedly connected to the upper surface of the base plate 1.

An electric push rod 8 is fixedly connected to the outer wall of the fixing block 7. A guide block 9 is fixedly installed at the output end of the electric push rod 8. The outer wall of the guide block 9 is slidably connected to the inner wall of the fixing block 7. A toothed column 10 is fixedly connected to the inner wall of the toothed column 10. An adjustment assembly 11 is provided on the outer wall of the toothed column 10. The adjustment assembly 11 includes an adjustment block 1101. The inner wall of the adjustment block 1101 is slidably connected to the outer wall of the toothed column 10, and the outer wall of the adjustment block 1101 is slidably connected to the inner wall of the fixing block 7. A locking block 12 is fixedly connected to the top outer wall of the adjustment block 1101.

[0024] Specifically, when the steel casing body 31 is placed on the outer wall of the road and bridge pile foundation and inserted into the ground along the inner wall of the base plate 1, the electric push rod 3 fixed to the inner wall of the mounting block 2 is activated to push the clamping block 4 to hold the steel casing body 31. This prevents the steel casing body 31 from shifting and facilitates the subsequent docking of the steel casing body 31. When the second steel casing body 31 is docked, the electric push rod 6 on the upper surface of the base plate 1 is activated to push the guide rail 5 to rise and fall, which can quickly limit the position of the second steel casing body 31. When the electric push rod 6 rises and falls to the appropriate position, the electric push rod 8 is activated to push the guide block 9 to slide. The guide block 9 will drive the adjusting component 11 to slide on the outer wall of the toothed column 10 and the inner wall of the fixing block 7, so that the adjusting component 11 drives the clamping block 12 to hold the second steel casing body 31, which can quickly fix the steel casing body 31 and prevent shifting during docking.

[0025] Example 2: Please see the appendix Figure 3 - Appendix Figure 5The adjusting assembly 11 includes an elastic element 1102. One end of the outer wall of the elastic element 1102 is fixedly connected to the inner top wall of the adjusting block 1101. The other end of the outer wall of the elastic element 1102 is fixedly connected to a toothed plate 1103. The outer wall of the toothed plate 1103 is slidably connected to the inner wall of the adjusting block 1101. The toothed ends of the lower surface of the toothed plate 1103 are meshed with the toothed ends of the toothed column 10. A guide column 1104 is fixedly connected to the lower surface of the toothed plate 1103. A counterweight 1105 is fixedly connected to the outer wall of the guide column 1104 near the top of the toothed plate 1103. The outer wall of the counterweight 1105 is slidably connected to the inner wall of the adjusting block 1101. A top block 1106 is slidably connected to the bottom end of the guide column 1104. One side of the outer wall of the top block 1106 is slidably connected to the guide block. The inner wall of guide block 9, the other side of the inclined outer wall of top block 1106 is engaged with the inner wall of adjusting block 1101, the lower surface of top block 1106 is fixedly connected with elastic element 2 1107, one end of elastic element 2 1107 is fixedly connected with the inner wall of guide block 9, the lower surface of top block 1106 is fixedly connected with connecting post 1108, the outer wall of connecting post 1108 is slidably connected with the inner wall of guide block 9, the bottom end of connecting post 1108 is fixedly connected with inclined block 1109, the outer wall of inclined block 1109 is fixedly connected with limiting block 1110, the outer wall of limiting block 1110 is slidably connected with magnetic block 1111, the outer wall of inclined block 1109 is slidably connected with the outer wall of magnetic block 1111, and the outer wall of magnetic block 1111 is slidably connected with the inner wall of guide block 9.

[0026] Specifically, when the electric push rod 8 pushes the guide block 9 to the appropriate position, the elastic element 1107 installed on the inner wall of the guide block 9 will push the top block 1106 to lift the guide post 1104. At the same time, the top block 1106 will lock the adjusting block 1101, enabling the guide block 9 and the adjusting block 1101 to move synchronously. The sliding of the guide post 1104 will drive the counterweight block 1105 and the toothed plate 1103 to move synchronously and compress the elastic element 1102. At this time, the toothed plate 1103 will disengage from the toothed post 10, thereby enabling the adjusting block 1101 to drive the locking block 12 to achieve a stable sliding effect. When the top block 1106 lifts the guide post 1104, the top block 1106... The connecting column 1108 will be pulled, causing the connecting column 1108 to slide the magnetic block 1111 through the tilting block 1109 and the limiting block 1110, which can achieve the effect of quickly retrieving the magnetic block 1111. When the second locking block 12 presses against the steel casing body 31, the top block 1106 will disengage from the guide column 1104 and the adjusting block 1101, so that the elastic element 1102 pushes the toothed plate 1103, and with the gravity of the counterweight block 1105, pulls the guide column 1104, which can make the toothed plate 1103 mesh with the toothed column 10, thus preventing the second locking block 12 from shifting. The second elastic element 1107 can be a steel leaf spring, a coil spring, a torsion bar spring, a rubber spring, etc., preferably a coil spring.

[0027] Please see the appendix Figure 4 The inner wall of the guide block 9 is slidably connected to the opening and closing plate 14, and the outer wall of the opening and closing plate 14 is slidably connected to the inclined outer wall of the top block 1106. The inner wall of the fixing block 7 is fixedly connected to the push plate 13, and the outer wall of the push plate 13 is slidably connected to the outer wall of the opening and closing plate 14.

[0028] Specifically, when the electric push rod 28 pulls the guide block 9 to the left push plate 13, the push plate 13 will push the opening and closing plate 14 to open, so that the top block 1106 can lift the guide post 1104. When the locking block 212 presses against the steel casing body 31, the electric push rod 28 is activated again to push the guide block 9, which will cause the top block 1106 to disengage from the guide post 1104. When the electric push rod 28 pulls the guide block 9, the top block 1106 will press against the guide post 1104 again, allowing the adjusting block 1101 to move. When the electric push rod 28 pushes the guide block 9 to the right push plate 13, the right push plate 13 will push the opening and closing plate 14 to close, so that the top block 1106, together with the connecting post 1108 and the tilting block 1109, pushes out the magnetic block 1111. Only when the guide block 9 reaches the left push plate 13 will the magnetic block 1111 retract.

[0029] Example 3: Please see the appendix Figure 3 and attached Figure 6 A magnetic block 2 15 is slidably connected to the inner wall of the fixed block 7. An installation component 16 is provided on the right outer wall of the magnetic block 2 15. An elastic element 3 18 is fixedly connected to the right outer wall of the magnetic block 2 15. A limit ring 17 is fixedly connected to the outer wall of one end of the elastic element 3 18. The outer wall of the limit ring 17 is fixedly connected to the inner wall of the fixed block 7.

[0030] Specifically, when the opening and closing plate 14 closes and pushes out the first magnetic block 1111, the opposite polarity of the first magnetic block 1111 and the second magnetic block 15 attracts each other, causing the guide block 9 to drive the second magnetic block 15 and the mounting assembly 16 to move synchronously. The mounting assembly 16 includes a hollow column 1601 and is fixed to the right outer wall of the second magnetic block 15, allowing the hollow column 1601 to slide on the outer wall of the limiting ring 17. The limiting ring 17 is fixed to the inner wall of the fixing block 7, which can prevent the hollow column 1601 from shifting. The limiting ring 17 and the mounting assembly 16 are connected by an elastic element 18, which allows the second magnetic block 15 to achieve a quick reset. A micro motor 1602 is fixedly connected to the inner wall of the hollow column 1601. A turntable 1603 is fixedly installed at the output end of the micro motor 1602. The outer wall of the turntable 1603 is rotatably connected to the inner wall of the hollow column 1601. The right side of the turntable 1603... A rotating block 1604 is fixedly connected to the outer side wall, and a magnetic block 1605 made of ferromagnetic material is fixedly connected to the inner wall of the turntable 1603. Since the magnetic block 15 and the mounting component 16 are located on the inner right side of the fixed block 7, the hollow column 1601 can be installed on the inner wall of the steel casing body 31. At this time, the fixed block 7 is moved on the inner wall of the guide rail 5, which allows the locking block 12 and the hollow column 1601 to drive the second steel casing body 31 to rotate synchronously. This facilitates the precise docking of the two sets of steel casing bodies 31. After the steel casing bodies 31 are docked, the cooperation of the magnetic block 1111 and the magnetic block 15 allows the electric push rod 8 to pull the hollow column 1601 off the steel casing body 31, thereby allowing the two sets of steel casing bodies 31 to be installed. The elastic element 18 can be a steel leaf spring, a coil spring, a torsion bar spring, a rubber spring, etc., preferably a coil spring.

[0031] Please see the appendix Figure 3 and attached Figure 7 A storage box 19 is fixedly connected to the inner wall of the fixed block 7. A baffle 20 is slidably connected to the inner wall of the storage box 19. The outer wall of the baffle 20 is slidably connected to the inner wall of the fixed block 7. An elastic element 21 is fixedly connected to the inner wall of the fixed block 7. A right-angle block 22 is fixedly connected to one side of the outer wall of the elastic element 21. The inner wall of the right-angle block 22 is rotatably connected to the outer wall of the fixed block 7. The outer wall of the right-angle block 22 is slidably connected to the left outer wall of the magnetic block 15. An inclined push block 23 is fixedly connected to the outer wall of the right-angle block 22. The outer wall of the inclined push block 23 is slidably connected to the inner wall of the elastic element 21.

[0032] Specifically, when guide block 9 pulls magnetic block 25, magnetic block 25 pushes right-angle block 22 to rotate. This, combined with elastic element 4 21 pushing right-angle block 22, allows right-angle block 22 to quickly push one side of the inclined push block 23 to rotate. The inclined surface of one side of the inclined push block 23 pushes elastic element 4 21 to slide, opening storage box 19. This allows the bolt inside storage box 19 to enter the inner wall of fixing block 7. At this time, left push plate 13 pushes opening and closing plate 14 to disengage magnetic block 1111 from magnetic block 25, and elastic element 3 18 pulls magnetic block 25 back to its original position, causing magnetic block 25 to push right-angle block 22 again. 2. Rotate and compress the elastic element 21, so that the tilting push block 23 on the other side can push the baffle 20 to close the storage box 19, which can achieve the effect of quantitative feeding. At this time, the bolt inside the fixed block 7 will be attracted to the rotating block 1604 by the magnetic block 1605, and the turntable 1603 will push the bolt to the docking point of the two sets of steel casing bodies 31. Before that, the micro motor 1602 is started to drive the turntable 1603, the rotating block 1604 and the bolt to rotate synchronously, which can achieve the effect of tightening the bolt. The elastic element 21 can be a steel leaf spring, a coil spring, a torsion bar spring, a rubber spring, etc., preferably a coil spring.

[0033] Example 4: Please see the appendix Figure 1 Appendix Figure 8 and attached Figure 9 A steel casing body 31 is slidably connected to the inner wall of the base plate 1. A positioning post 24 is slidably connected to the inner wall of the steel casing body 31. An inclined support plate 26 is fixedly connected to the outer wall of the positioning post 24. The right outer wall of the inclined support plate 26 is slidably connected to the inner wall of the support post 27. The outer wall of the support post 27 is slidably connected to the inner wall of the steel casing body 31. A rotating rod 28 is rotatably connected to the inner wall of the inclined support plate 26. An adjusting rod 29 is rotatably connected to the outer wall of the rotating rod 28. A limiting plate 25 is rotatably connected to the outer wall of the adjusting rod 29. The lower surface of the limiting plate 25 is fixedly connected to the upper surface of the steel casing body 31. A snap-fit ​​plate 30 is slidably connected to the outer wall of the positioning post 24. The outer wall of the snap-fit ​​plate 30 snaps into the inner wall of the steel casing body 31. The outer wall of the steel casing body 31 is rotatably connected to the inner wall of the other rotating rod 28.

[0034] Specifically, when the two sets of steel casing bodies 31 are connected and the bolts are tightened, the bolts will push the positioning column 24, and the positioning column 24 will slide on the inner wall of the limiting plate 25, so that the limiting plate 25 can stably push the inclined support plate 26 to slide. The inclined surface of the inclined support plate 26 pushes the support column 27 to rise and fall, so that the support column 27 can connect with the two sets of steel casing bodies 31 to improve the strength of the steel casing bodies 31. The inclined support plate 26 pulls the rotating rod 28, and the adjusting rod 29 pushes the locking plate 30, so that the locking plate 30 locks the two sets of steel casing bodies 31, so that the connection between the two sets of steel casing bodies 31 can achieve a tight connection.

[0035] Workflow: When the two steel casing bodies 31 are docked, the electric push rod 3 is activated to push the clamping block 4 to clamp and fix the first steel casing body 31. At this time, the electric push rod 6 is activated to drive the guide rail 5 and the fixing block 7 to rise and fall, moving the fixing block 7 to the lower side of the second steel casing body 31. At this time, the hollow column 1601 will be stuck in the lower inner wall of the second steel casing body 31. The electric push rod 8 is activated to push the guide block 9 to slide, so that the guide block 9, together with the top block 1106 and the elastic element 1107, drives the adjusting block 1101 to slide. Thus, the adjusting block 1101 drives the clamping block 12 to clamp the second steel casing body 31. Thus, when the guide rail 5 drives the fixing block 7 to move, the hollow column 1601 and the clamping block 12 will drive the steel casing body 31 to rotate synchronously, which can achieve the effect of precise adjustment and positioning. When the guide block 9 moves again after being clamped by the second clamping block 12, it will disengage from the adjusting block 1101. The push plate 13 will be energized to open and close the plate 14, and the top block 1106 will push the connecting column 1108 to push out the magnetic block 1111. This allows the magnetic block 1111 to attract the magnetic block 2 15, which facilitates the movement of the installation component 16. When the top block 1106 is closed, the elastic element 1102 will push the toothed plate 1103, and with the counterweight 1105, the toothed plate 1103 will mesh with the toothed column 10, which can quickly fix the position of the adjusting block 1101. At this time, the electric push rod 28 is activated to pull the guide block 9 and the magnetic block 1111, so that the magnetic block 2 15 pulls the hollow column 1601 to slide. The sliding of the magnetic block 2 15 will drive the right-angle block 22 to rotate, so that the tilting push block 23 pushes the elastic element 4 21 to slide and open the baffle 20, which can allow the bolt to automatically enter the fixed block 7. When the guide block 9 slides to the appropriate position, the push plate 13 will open the opening and closing plate 14, thereby allowing the magnetic block 1111 to disengage from the magnetic block 2 15. This causes the elastic element 3 18 to pull the magnetic block 2 15 and the hollow column 1601 to reset. The reset of the magnetic block 2 15 will drive the right-angle block 22 to reset and cause the baffle 20 to close the storage box 19, which can achieve the effect of precise control of the threaded material discharge. The hollow column 1601 pushes the bolt into the joint of the two sets of steel casing bodies 31. At this time, the micro motor 1602 is started to drive the rotating block 1604 to rotate, which can achieve the effect of quickly tightening the bolt. By pushing the positioning column 24 with bolts, the positioning column 24 pushes the inclined support plate 26 to lift the support column 27, so that the support column 27 connects with the two steel casing bodies 31, which can improve the strength of the steel casing bodies 31. The inclined support plate 26 drives the rotating rod 28 and the adjusting rod 29, so that the rotating rod 28 pushes the snap-fit ​​plate 30 to clamp the two steel casing bodies 31.
