Description

Technical Field

[0001] This invention relates to the field of shoulder slipform construction technology; specifically, this invention relates to an integrated shoulder slipform device that can prevent grout leakage from the bottom of the side formwork. Background Technology

[0002] In conventional slipform construction for shoulder protection, to protect the slipform and prevent its bottom from impacting the ground substrate and causing damage that could affect the shoulder construction, the slipform is typically lowered to a height greater than the ground substrate, creating a safety gap between the slipform bottom and the substrate. However, this safety gap can lead to grout leakage, causing a large amount of concrete to overflow and be wasted during shoulder construction. Currently, the solution to grout leakage is to reduce the slipform height. However, because the ground substrate is already compacted and uneven, there is a risk of hard impacts on the slipform. Therefore, existing technologies are limited and cannot effectively solve the grout leakage problem. Summary of the Invention

[0003] In view of this, the present invention provides an integrated shoulder slipform device that can prevent grout leakage at the bottom of the side formwork, thereby solving or at least alleviating the problem of a large amount of grout leakage in the gap between the side formwork and the ground base during shoulder slipform construction in the prior art.

[0004] To achieve the aforementioned objective, the present invention provides an integrated shoulder-protecting sliding formwork device capable of preventing grout leakage at the bottom of the side formwork, comprising a side formwork, wherein hollow housings are provided on both sides of the front end of the side formwork, one side of the two housings facing each other is flush with the inner side of the side formwork, the front end of the housing is provided with a grooving cutter capable of cutting an inner wall in the ground that is flush with the inner surface of the side formwork and the outer wall located outside the side formwork, forming a ground groove, and a horizontal plate whose lower surface is flush with the bottom of the side formwork is fixedly installed at the rear end of the bottom of the housing, and a return plate for pressing soil in the ground groove into the bottom of the horizontal plate is installed inside the housing, and a return push rod for controlling the forward and backward displacement of the return plate is installed on the outer surface of the housing, and the return plate reciprocates once when the side formwork moves forward a distance equal to the length of the horizontal plate.

[0007] Preferably, the bottom of the housing is provided with a pre-compression assembly located in front of the horizontal plate. The pre-compression assembly includes an upper baffle, an inclined baffle, and a rear baffle. The upper baffle is flush with the horizontal plate and fixedly installed inside the housing. The rear end of the inclined baffle is rotatably engaged with the housing and fits against the front end of the upper baffle. The rear baffle fits against the rear end of the inclined baffle and is arc-shaped with the rotation center of the inclined baffle as the center. The bottom of the rear baffle contacts the bottom wall of the ground trough and can be disengaged from the ground trough by sliding upward.

[0008] Preferably, a soil filling port is provided between the horizontal plate and the rear baffle. Above the soil filling port, a soil filling trough is rotatably installed inside the machine housing via a rotating shaft. The volume of the soil filling trough is adapted to the volume of the space enclosed between the horizontal plate and the ground trough. A stepper motor connected to the rotating shaft and driving the soil filling trough to rotate 180° forward and backward is installed on the machine housing. The stepper motor is signal-connected to the return push rod. When the return plate moves backward or forward until the volume formed between it and the front side of the rear baffle and the lower surface of the upper baffle is adapted to the volume position of the soil filling trough, the stepper motor drives the soil filling trough to rotate 180° forward or backward.

[0009] Preferably, a synchronization plate adapted to the inclined baffle is rotatably installed in the soil filling groove, the front end of the synchronization plate is rotatably connected to the soil filling groove, and a synchronization component is provided between the synchronization plate and the inclined baffle to keep the synchronization plate parallel to the inclined baffle.

[0010] Preferably, the synchronization component includes a mandrel, a first toothed groove, a second toothed groove, a first rack, and a second rack. The mandrel is slidably disposed within the rotating shaft, with its front end extending from the rotating shaft. The first toothed groove and the second toothed groove are respectively disposed on the circumferential surfaces of the front ends of the synchronization plate and the inclined baffle. The first rack and the second rack are respectively engaged with the first toothed groove and the second toothed groove. The first rack is disposed inside the filler groove. The first rack slides axially with the rotating shaft and rotates circumferentially with the rear end of the mandrel. The second rack slides within the housing and rotates circumferentially with the front end of the mandrel.

[0011] Preferably, the synchronization component further includes a first bushing, a gear pair, and a second bushing. The bottom end of the first bushing is rotatably sleeved on the rear end of the mandrel. The first bushing is slidably engaged with the rotating shaft, and the first rack is fixedly installed on the top end of the first bushing. The gear pair is rotatably installed in the filler groove, and the gear pair connects the first rack and the first gear groove. The second bushing is rotatably sleeved on the front end of the mandrel, and the second bushing is slidably installed on the housing. The second rack is fixedly installed on the bottom end of the second bushing.

[0012] Preferably, an arc-shaped cover centered on the rotating shaft is rotatably mounted on the housing, the soil filling groove is fixedly installed inside the arc-shaped cover, and the surface of the arc-shaped cover is provided with a soil inlet adapted to the groove opening of the soil filling groove. A hopper is fixedly mounted on the housing, the bottom end of the hopper is in contact with the surface of the arc-shaped cover, and the bottom end of the hopper is provided with a soil outlet adapted to the soil inlet.

[0013] Preferably, one side of the housing is provided with an arc-shaped sliding groove, and an arc-shaped slider fixedly connected to the rear baffle is provided in the arc-shaped sliding groove. The other side of the housing is provided with a lifting frame, and a guide rod fixedly connected to the rear baffle is slidably arranged in the lifting frame. The top of the lifting frame is connected to a lifting rack that can be raised and lowered. The lifting rack meshes with a circular gear sleeved on the front end of the rotating shaft. When the soil filling groove rotates 180° clockwise or counterclockwise, the rear baffle moves up or down once.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: This application involves creating a ground trench in the area corresponding to the side formwork's displacement direction, and then backfilling and compacting the loose soil formed during trenching into the trench to seal the bottom of the side formwork. Since the hardness of the re-compacted soil is significantly lower than that of the original ground soil, it avoids hard impacts on the side formwork. On one hand, this allows the side formwork to be lowered to a lower height, ensuring its bottom is flush with the top opening of the ground trench, eliminating the safety gap between the side formwork and the ground in existing technologies and greatly reducing grout leakage gaps. On the other hand, the backfilling seals the bottom of the trench, preventing concrete leakage and further improving the grout-proofing effect. Furthermore, the backfilling process effectively restores the ground surface, avoiding the need for secondary backfilling. Attached Figure Description

Detailed Implementation

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below. 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.

[0018] like Figures 1 to 9 As shown, this application provides an integrated shoulder slipform device that can prevent grout leakage at the bottom of the side mold. It includes a side mold 1, and hollow housings 2 are provided on both sides of the front end of the side mold 1. The opposite side of the two housings 2 is flush with the inner side of the side mold 1. The front end of the housing 2 is provided with a grooving knife 3 that can cut an inner wall in the ground that is flush with the inner surface of the side mold 1 and the outer wall is located outside the side mold 1. A horizontal plate 4 with its lower surface flush with the bottom of the side mold 1 is fixedly installed at the rear end of the bottom of the housing 2. A return plate 5 for pressing the soil in the ground trough into the bottom of the horizontal plate 4 is installed inside the housing 2. A return push rod 6 for controlling the forward and backward displacement of the return plate 5 is installed on the outer surface of the housing 2. When the side mold 1 moves forward a distance equal to the length of the horizontal plate 4, the return plate 5 reciprocates once.

[0019] During shoulder construction, the grooving cutter 3 grooves the ground that the slipform will pass over in front of it, breaking up the soil. After grooving, the return material pusher 6 drives the return material plate 5 to push the soil back to the bottom of the horizontal plate 4 for compaction. The soil after secondary compaction is looser than the original ground soil, and at the same time, it can effectively fill the bottom of the side formwork 1. On the one hand, the soil after secondary compaction will not cause a hard impact on the side formwork 1, so that the bottom height of the side formwork 1 can be lowered compared to existing technologies, and it can move along the opening of the ground trench. On the other hand, when the side formwork 1 moves onto the secondary compacted soil, the secondary compacted soil can effectively backfill the ground trench and seal the bottom of the side formwork 1.

[0020] In summary, the integrated shoulder slipform device of this application, which prevents grout leakage from the bottom of the side formwork 1, breaks up the soil while simultaneously creating a groove in the ground in the direction of the side formwork 1's movement. Then, before the side formwork 1 arrives, the soil is backfilled into the ground groove. On one hand, because the soil does not possess the property of hard impact on the side formwork 1, the side formwork 1 can be lowered to a position where its bottom height is flush with the opening of the ground groove, eliminating the gap between the side formwork 1 and the ground in the prior art and greatly reducing the grout leakage gap. On the other hand, the backfilled soil is compacted and fills the ground groove, effectively sealing the bottom of the side formwork 1 and further reducing grout leakage.

[0021] like Figure 2 As shown, a grooving motor 7 for driving the grooving knife 3 to rotate is installed on the housing 2, and the inner side of the grooving knife 3 is flush with the inward side of the housing 2.

[0022] Lifting plates 8 are fixedly installed on both sides of the return plate 5. The outer surface of the lifting plate 8 is flush with the inner wall of the ground trough. A translation plate 9 located inside the ground trough is sleeved on the outside of the lifting plate 8. The lifting plate 8 can be lifted and lowered on the translation plate 9. The top of the lifting plate 8 and the translation plate 9 are located above the ground trough. The top of the translation plate 9 is connected to the return push rod 6. A rotating column 10 is provided on the outer side of the top of the lifting plate 8. A guide rail 11 that can be lifted and lowered is provided on the surface of the housing 2. The rotating column 10 moves the return plate 5 from the top of the soil in the ground trough to its front side by passing through the upper surface of the guide rail 11.

[0023] During the forward resetting process of the return plate 5, the rotating column 10 moves from the rear end of the guide rail 11 to the top surface of the guide rail 11 and moves along the top surface of the guide rail 11. During this process, the rotating column 10, guided by the guide rail 11, drives the lifting plate 8 to move upward. At this time, the lifting plate 8 drives the return plate 5 to move upward. When the rotating column 10 moves to the front end of the guide rail 11, the return plate 5 moves to the front side of the soil piled in the ground trench. When the rotating column 10 disengages from the front end of the guide rail 11, the return plate 5 automatically falls into the ground trench. When the return plate 5 moves backward and pushes the soil behind it towards the horizontal plate 4, when the rotating column 10 passes the rear end of the guide rail 11, the rotating column 10 will push against the guide rail 11. On the one hand, the guide rail 11 will move upward; on the other hand, the rotating column 10, after being subjected to the reaction force of the guide rail 11, will better insert itself into the soil downward, improving the bulldozing effect.

[0024] Specifically, a notch is provided at the bottom of the side of the housing 2, through which the bottom end of the housing 2 is inserted. The outer side of the sliding plate 9 is flush with the outer side of the housing 2. By providing the notch, a space is formed between the notch and the ground trough for the top of the sliding plate 9 to extend upward into the ground trough.

[0025] The bottom of the housing 2 is provided with a pre-compression assembly located in front of the horizontal plate 4. The pre-compression assembly includes an upper baffle 12, an inclined baffle 13, and a rear baffle 14. The upper baffle 12 is flush with the horizontal plate 4 and is fixedly installed inside the housing 2. The rear end of the inclined baffle 13 is rotatably engaged with the housing 2 and fits against the front end of the upper baffle 12. The rear baffle 14 fits against the rear end of the inclined baffle 13 and is arc-shaped with the rotation center of the inclined baffle 13 as the center. The bottom of the rear baffle 14 contacts the bottom wall of the ground trough and can be disengaged from the ground trough by sliding upward.

[0026] By setting up a pre-compression component, during the process of the return plate 5 pushing the soil backward, the soil, after being lowered by the rear baffle 14, will first push against the inclined baffle 13 before contacting the rear baffle 14. When the soil contacts the rear baffle 14, it is blocked by the rear baffle 14, causing the soil to continue pushing against the inclined baffle 13. When the inclined baffle 13 is pushed to a horizontal state, the soil is compacted.

[0027] Afterwards, the rear baffle 14 moves upward away from the ground trough, causing the return plate 5 to continue pushing the soil backward, eventually pushing the soil under the horizontal plate 4 for another compaction.

[0028] After setting up the preloading component, the soil can be pre-compacted to improve the compaction effect of the soil.

[0029] A soil filling port 15 is provided between the horizontal plate 4 and the rear baffle 14. A soil filling trough 17 is rotatably installed in the housing 2 above the soil filling port 15 via a rotating shaft 16. The volume of the soil filling trough 17 is adapted to the volume of the space enclosed between the horizontal plate 4 and the ground trough. A stepper motor 18 is installed on the housing 2, which is connected to the rotating shaft 16 and drives the soil filling trough 17 to rotate forward and backward 180°. The stepper motor 18 is signal connected to the return push rod 6. When the return plate 5 moves backward or forward until the volume formed between it and the front side of the rear baffle 14 and the lower surface of the upper baffle 12 is adapted to the volume position of the soil filling trough 17, this position is set to a preset position, and the stepper motor 18 drives the soil filling trough 17 to rotate forward or backward 180°. A sensor (not shown) can be set at a preset position. When the return plate 5 moves to the preset position, the sensor sends a feedback signal to the PLC control system. The PLC control system then controls the return push rod 6 to stop, and the stepper motor 18 rotates 180° clockwise. After that, the stepper motor 18 stops, and the return push rod 6 drives the return plate 5 to continue moving backward, pressing the soil into the bottom of the horizontal plate 4. When the return plate 5 returns to its original position and passes the sensor, the stepper motor 18 rotates 180° counterclockwise to reset the soil filling groove 17.

[0030] In this embodiment, the stepper motor 18 is signal-connected to the return push rod 6, and drives the soil filling trough 17 to rotate when the return plate 5 moves to a designated position below the upper baffle 12. This allows the soil in the soil filling trough 17 to fall from the soil filling port 15 to the rear side of the soil pushed backward by the return plate 5, so that the replenished soil can be pushed into the horizontal plate 4 together. Thus, through the soil filling operation, it can be ensured that the backfilled soil has a sufficient amount, ensuring that the soil backfill can fill the ground trough below the side mold 1 and effectively compact it, thereby improving the grout leakage prevention effect.

[0031] A synchronization plate 19 adapted to the inclined baffle 13 is rotatably installed inside the soil filling trough 17. The soil in the soil filling trough 17 is located on the top of the synchronization plate 19. The front end of the synchronization plate 19 is rotatably connected to the soil filling trough 17. A synchronization component is provided between the synchronization plate 19 and the inclined baffle 13 to keep the synchronization plate 19 and the inclined baffle 13 parallel.

[0032] By setting up a synchronization plate 19 and a synchronization component, when the inclined baffle 13 is pushed up by the soil, the synchronization component drives the synchronization plate 19 to swing synchronously with the inclined baffle 13. The synchronization plate 19 pushes out some of the soil in the filling trough 17. At this time, the amount of soil remaining in the filling trough 17 is matched with the amount of soil required when the inclined baffle 13 swings to a horizontal state.

[0033] Therefore, when the return plate 5 moves to the designated position below the upper baffle 12, and the stepper motor 18 drives the soil filling trough 17 to rotate 180° clockwise, the amount of soil in the soil filling trough 17 matches the amount of soil required when the inclined baffle 13 is pushed up to a horizontal state, thereby improving the accuracy of soil filling and avoiding excessive soil filling.

[0034] The synchronization assembly includes a spindle 20, a first toothed groove 21, a second toothed groove 22, a first rack 23, and a second rack 24. The spindle 20 is slidably disposed within the rotating shaft 16, with its front end extending from the rotating shaft 16. The first toothed groove 21 and the second toothed groove 22 are respectively disposed on the circumferential surfaces of the front ends of the synchronization plate 19 and the inclined baffle 13. The first rack 23 and the second rack 24 mesh with the first toothed groove 21 and the second toothed groove 22, respectively. The first rack 23 is disposed inside the soil filling groove 17. The first rack 23 slides axially with the rotating shaft 16 and rotates circumferentially with the rear end of the spindle 20. The second rack 24 is slidably disposed within the housing 2 and rotates circumferentially with the front end of the spindle 20.

[0035] By setting the spindle 20 and configuring the first rack 23 and the second rack 24 to rotate in circumferential direction with the spindle 20, the synchronization assembly can ensure that the synchronization plate 19 and the inclined baffle 13 are in a parallel state during the rotation of the soil filling groove 17, and are not affected by the rotation of the soil filling groove 17.

[0036] When the inclined baffle 13 is swung upwards by the soil, the second tooth groove 22 drives the second rack 24 to move forward, and the second rack 24 pulls the spindle 20 forward. The spindle 20 drives the first rack 23 to move forward, and the first rack 23 drives the synchronization plate 19 to swing at the same angle as the inclined baffle 13 through the first tooth groove 21, thereby ensuring that the synchronization plate 19 is always parallel to the inclined baffle 13.

[0037] The synchronization assembly also includes a first bushing 25, a gear pair 26, and a second bushing 27. The bottom end of the first bushing 25 is rotatably fitted onto the rear end of the spindle 20. The first bushing 25 is slidably fitted onto the rotating shaft 16, and the first rack 23 is fixedly installed on the top end of the first bushing 25. The gear pair 26 is rotatably installed in the filler groove 17, and the gear pair 26 connects the first rack 23 and the first gear groove. The second bushing 27 is rotatably fitted onto the front end of the spindle 20, and the second bushing 27 is slidably installed on the housing 2. The second rack 24 is fixedly installed on the bottom end of the second bushing 27.

[0038] Specifically, the top of the rotating shaft 16 is provided with a through groove for the sliding of the first bushing 25. The gear pair 26 is designed to keep the first rack 23 away from the bottom of the synchronization plate 19, ensuring that the synchronization plate 19 will not collide with the first rack 23, thereby ensuring the effective operation of the synchronization assembly. A spring 36 is provided inside the rotating shaft 16 and sleeved on the mandrel 20. When the inclined baffle 13 is pushed up by the soil, the spring 36 is compressed by being displaced outward within the rotating shaft 16 through the mandrel 20. The spring 36 not only provides pressure to the soil for the preloading assembly, but also serves to reset the inclined baffle 13 and the synchronization plate 19.

[0039] An arc-shaped cover 28 centered on a rotating shaft 16 is rotatably mounted on the casing 2. A soil filling trough 17 is fixedly installed inside the arc-shaped cover 28, and the surface of the arc-shaped cover 28 is provided with a soil inlet that matches the opening of the soil filling trough 17. A hopper 29 is fixedly mounted on the casing 2. The bottom end of the hopper 29 is in contact with the surface of the arc-shaped cover 28, and the bottom end of the hopper 29 is provided with a soil outlet that matches the soil inlet.

[0040] The hopper 29 is kept full of soil, so that the soil filling trough 17 is full in the initial state. When the synchronous plate 19 swings upward with the inclined baffle 13, it will push the excess soil in the soil filling trough 17 into the hopper 29, improving the accuracy of soil filling.

[0041] An arc-shaped slide groove 30 is provided on one side of the housing 2. An arc-shaped slider 31 fixedly connected to the rear baffle 14 is provided in the arc-shaped slide groove 30. A lifting frame 32 is provided on the other side of the housing 2. A guide rod 33 fixedly connected to the rear baffle 14 is slidably provided in the lifting frame 32. A lifting rack 34 that can be raised and lowered is connected to the top of the lifting frame 32. The lifting rack 34 meshes with a round gear 35 sleeved on the front end of the rotating shaft 16. When the soil filling groove 17 rotates forward or backward 180°, the rear baffle 14 moves up or down once.

[0042] When the stepper motor 18 drives the soil filling trough 17 to rotate, the rotating shaft 16 will drive the spur gear 35 to rotate. The spur gear 35 will drive the lifting rack 34 to move up and down. The lifting rack 34 will drive the lifting frame 32 to move up and down. The lifting block will drive the rear baffle 14 to move up and down through the guide rod 33. During this process, the guide rod 33 will move laterally in the lifting frame 32, and the arc-shaped slider 31 will move within the arc-shaped groove 30, so that the rear baffle 14 will move upward in a circular motion with the front end of the inclined baffle 13 as the center, and provide space for the movement of the return plate 5.

[0043] The specific work process for this application is as follows: The grooving motor 7 drives the grooving blade 3 to rotate, grooving the ground and causing the broken soil to fall into the groove. The return push rod 6 moves the return plate 5 forward. When the return plate 5 reaches the preset position below the upper baffle 12, the return push rod 6 stops, and the stepper motor 18 drives the filling groove 17 to rotate 180° in the opposite direction, so that the opening of the filling groove 17 faces upward. At the same time, the rear baffle 14 falls to its lowest position. Then, the return push rod 6 continues to move forward, causing the return plate 5 to move from the top of the soil in front of it to the front of the soil.

[0044] The return material push rod 6 pulls the return material plate 5 backward. As the return material plate 5 moves to the preset position below the upper baffle 12, the inclined baffle 13 is pushed up by the soil, and the synchronous plate 19 swings in the filling trough 17 through the synchronous component. After the return material plate 5 moves to the preset position, the stepper motor 18 drives the filling trough 17 to rotate 180° clockwise, so that the opening of the filling trough 17 is facing downward. At this time, the soil in the filling trough 17 will fall from the filling opening 15 into the ground trough. At the same time, the rotating shaft 16 drives the lifting rack 34 to move upward through the circular gear 35. The lifting rack 34 drives the rear baffle 14 to move upward to the highest position through the lifting frame 32.

[0045] Afterwards, the return push rod 6 pulls the return plate 5 to continue moving backward. The return plate 5 pushes the soil into the bottom of the horizontal plate 4 and compacts it, then backfills the soil into the ground trench.

[0046] The technical scope of this invention is not limited to the contents of the above specification. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the scope of this invention.
