Technical Field
[0001] This invention relates to the field of tunnel construction technology, and in particular to an intelligent vibratory compaction device and its construction method for the sidewalls of open-cut tunnels. Background Technology
[0002] Tunnel sidewalls play a crucial role in supporting and maintaining the long-term stability of the tunnel. They need sufficient strength, durability, and certain resistance to freezing, seepage, and erosion. During the construction of tunnel sidewalls, air bubbles are generated in the concrete during pouring. The poured concrete must be vibrated to remove these air bubbles and compacted to ensure a dense bond, eliminating honeycomb and pitting defects, thereby improving its strength and ensuring the quality of the tunnel sidewall concrete. However, due to the complexity of the tunnel sidewall structure, its height, and dense reinforcement, manual vibration is required after concrete pouring, often supplemented by adsorption vibrators. This process is not only unsafe but also difficult for workers to operate in, with limited space and inconsistent vibration quality, relying heavily on worker diligence and experience.
[0003] Chinese patent document CN 206386130 U describes a full-section external vibration device for tunnel concrete pouring, but this device cannot be adjusted according to the position of the reinforcing bars to ensure that the vibration process does not interfere with the reinforcing bars; Chinese patent document CN 206267857 U describes an automatic vibration system for concrete pouring in tunnel secondary lining, which also has the above problems and has defects in use, requiring improvement.

[0015] In a preferred embodiment, a construction method for an intelligent vibratory compaction device for the sidewalls of an open-cut tunnel includes the following steps:
[0016] S1. Install guide rails on the upper part of the foundation pit, and then install a movable frame across the two guide rails;
[0017] S2. Lock the mobile frame, and install the crossbeam, vibrating assembly, jacking assembly and lifting beam on the upper part of the mobile frame respectively;
[0018] S3. Perform functional adjustments on the vibratory assembly to ensure the vibrator operates normally;
[0019] S4. Tie and fix the steel bars of the tunnel segments in the foundation pit, and then set up the formwork;
[0020] S5. The moving vibratory assembly acquires top images between the reinforcing bars through a camera, screens and identifies gaps in the reinforcing bars, and records them.

[0026] The beneficial effects of this invention are as follows: By setting up a mobile frame on the foundation pit and then using a crossbeam to set up the vibration assembly, manual operation can be replaced. Simultaneously, vibration is performed using a remote control, matching different vibration parameters according to different concrete types. The vibrator automatically moves up and down, reducing manual workload and ensuring construction safety. At the same time, vibration efficiency and effect are better, especially improving the vibration quality in curved areas. The vibrator, driven by the drive wheel, quickly moves to the gaps in the reinforcing mesh and then lowers. The two vibration assemblies on the same side cooperate with each other, serving as backups. If either vibration assembly malfunctions, the other vibration assembly quickly follows up using previously marked data, ensuring work continuity and good economic benefits.

Detailed Implementation
[0048] like Figure 1-5 A smart vibratory compaction device for the sidewalls of an open-cut tunnel includes a movable frame 3 mounted on the upper side of a pit 1. Two crossbeams 4 are movable on both sides of the movable frame 3, and a vibratory compaction assembly 6 is slidably mounted on the lower side of the crossbeams 4. The vibratory compaction assembly 6 includes a control box 611, and a vibrator 609 is mounted at the lower part of the control box 611. The vibrator 609 is used to vibrate the tunnel segment 2 within the pit 1. This structure facilitates easy installation and dismantling. The vibratory compaction assembly 6 is moved on the pit 1 by the movable frame 3, thereby facilitating the vibration operation during the pouring of the tunnel segment 2. The vibrator 609 of the vibratory compaction assembly 6 can move up and down in the vertical direction, thus ensuring the quality of the concrete pouring within the tunnel segment 2.
[0049] like Figure 6-7In the preferred embodiment, guide rails 5 are provided on both sides of the top of the pit 1. The guide rails 5 are used to guide the movement of the mobile frame 3. A hanging beam 8 is provided on the upper part of the crossbeam 4. The hanging beam 8 is slidably mounted on the top of the mobile frame 3 and is connected to the mobile frame 3 through a jacking assembly 7. This structure allows the guide rails 5 to limit the movement of the mobile frame 3, ensuring that the mobile frame 3 can move along the designed route. The hanging beam 8 can move the vibrating assembly 6 in the laying direction perpendicular to the tunnel segment 2, ensuring that the vibrating assembly 6 can operate in two directions, better avoiding the reinforcing steel in the tunnel segment 2, and ensuring safety and stability during vibration.
[0050] like Figure 8-9 In the preferred embodiment, the jacking assembly 7 includes a cylinder 701 and a first mounting plate 705 respectively disposed on both sides of the movable frame 3. A jack rod 702 is provided on one side of the cylinder 701. The ends of the cylinder 701 and the jack rod 702 are respectively hinged to a first hinge seat 703 and a second hinge seat 704. The first hinge seat 703 is connected to the movable frame 3, and the second hinge seat 704 is connected to the side wall of the lifting beam 8. A guide rod 706 is provided on the first mounting plate 705. A through hole 801 and a through groove 802 are provided through the lifting beam 8. Multiple marking lines 803 are provided on the outer side of the lifting beam 8. The guide rod 706 passes through the through hole 801. The lifting beam 8 is connected to the crossbeam 4 through multiple connecting plates 9. This structure allows the position of the lifting beam 8 to be changed by the jack rod 702, thereby changing the position of the crossbeam 4. The overall driving force is stable, the movement is fast, and the support force is sufficient.
[0051] like Figure 10-13 In the preferred embodiment, the upper part of the control box 611 is provided with a base plate 601 and a load-bearing block 602. The base plate 601 is provided with drive wheels 603 on both sides. The upper part of the load-bearing block 602 is connected to a sliding wheel 605 through a first threaded rod 604. The sliding wheel 605 slides inside the crossbeam 4. The drive wheel 603 abuts against the lower surface of the crossbeam 4. The control box 611 is also provided with a cable winding module 606 and a signal module 607. The connecting cable 610 is wound around the cable winding module 606. The vibrator 609 is connected to the cable winding module 606 through the connecting cable 610. The lower part of the control box 611 is provided with a zero-point positioning module 608. The connecting cable 610 passes through the zero-point positioning module 608. This structure allows the drive wheel 603 to push the vibratory assembly 6 from below to move, and the sliding wheel 605 to ensure the safety of the vibratory assembly 6 during hoisting. The overall constraint effect is good. The cable winding module 606 winds up and unwinds the connecting cable 610, avoiding the mess of the cable from affecting subsequent operations. The zero-point positioning module 608 can obtain the position of the vibratory rod 609 when it is lowered, and the control accuracy is high.
[0052] like Figure 17-19In the preferred embodiment, the crossbeam 4 is provided with two vibrating components 6, and a safety distance control component 10 is detachably provided between the two vibrating components 6. The safety distance control component 10 includes two boxes 1001 arranged opposite to each other. A sliding rod 1002 is slidably provided in the box 1001. A spring 1009 abuts between the two sliding rods 1002. A contact plate 1003 is provided at the end of the sliding rod 1002. An arc groove 1008 matching the shape of the sliding wheel 605 is provided on the contact plate 1003. Two vibrating components 6 work together to switch between multiple modes. The safety distance control component 10 prevents collisions between the two vibrating components 6. A pressure sensor is provided on one side of the sliding wheel 605. By pressing the safety distance control component 10 between the two vibrating components 6, the relative position between the two vibrating components 6 can be determined, thus meeting the usage requirements. When the spacing of the lowered rebar is obtained, the values of the safety distance control component 10 and the pressure sensor are matched to ensure that the two vibrating components 6 can operate in single steps according to the spacing between the rebar mesh. After the vibration operation is completed, the front vibrating component 6 moves one set distance, and then the rear vibrating component 6 pushes the safety distance control component 10 forward. When the pressure sensor obtains the same value as the set value, the distance between the two vibrating components 6 is the ideal step distance. Then the above process is repeated for operation.
[0053] In the preferred embodiment, the housing 1001 has a channel 1004, a step 1005 on one side of the channel 1004, a protrusion 1012 at one end of the slide rod 1002, and the slide rod 1002 and the channel 1004 are slidably connected. The housing 1001 has a clearance groove 1006, and the clearance grooves 1006 on both sides are connected by screws 1007 and nuts 1010. The contact plate 1003 is connected to the slide rod 1002 by screws 1007, and a recess 1011 is also provided on the inner side of the slide rod 1002. The end of the spring 1009 is fixed in the recess 1011. This structure ensures that the contact force between the vibrating components 6 on both sides and the two slide rods 1002 is balanced, the overall contact is stable, and the force transmission effect is better.
[0054] like Figure 14-16In the preferred embodiment, the control box 611 is detachably equipped with a positioning component 11 on the side near the foundation pit 1. The positioning component 11 is equipped with a spraying component 12, a camera 13, a ranging module 14, and an air pump 15. The spraying component 12 has a nozzle 1205 at its end, which is used to mark the positioning inside the foundation pit 1. The camera 13 is used to acquire the arrangement information of the steel bars in the tunnel segment 2. The ranging module 14 is used to measure and position the distance between the positioning component 11 and the foundation pit 1. The air pump 15 is used to provide a driving source for the nozzle 1205. With this structure, the high-speed camera 13 can acquire two nodes (i.e., the start and end points) of the steel mesh as needed, and the safety distance control component 10 can acquire the overall length of the cast steel mesh. After the calculation module in the control box 611 performs the calculation, it marks the position where vibration can be performed. Then, the spraying component 12 marks the powder inside the foundation pit 1, which facilitates the rapid movement and positioning of the subsequent vibration component 6.
[0055] In a preferred embodiment, the spraying assembly 12 is disposed in the middle of the positioning assembly 11. The spraying assembly 12 includes a fixed base 1201, which is fixedly connected to the positioning assembly 11. The fixed base 1201 is provided with a sleeve 1202 and a telescopic cylinder 1203, which are slidably connected to the telescopic cylinder 1202. The nozzle 1205 is disposed at the end of the telescopic cylinder 1203. A locking block 1204 is provided on one side of the nozzle 1205. The locking block 1204 is provided with a pneumatic valve 18 for controlling the internal channel of the telescopic cylinder 1203.
[0056] The lower part of the fixed base 1201 and the locking block 1204 is provided with a first vertical plate 1206 and a second vertical plate 1207. The lower side of the spray assembly 12 is provided with a length adjustment assembly 16. The length adjustment assembly 16 includes a second mounting plate 1601. The second mounting plate 1601 is connected to the positioning assembly 11. A first motor 1602 is provided on one side of the second mounting plate 1601. A first gear 1603 is fixed at the end of the first motor 1602. The first gear 1603 is meshed with a second gear 1604. A second threaded rod 1605 is fixed in the middle of the second gear 1604. The second threaded rod 1605 passes through the first vertical plate 1206 and the second vertical plate 1207. A disc 1606 is provided at the end of the second threaded rod 1605.
[0057] The positioning assembly 11 is also provided with a third hinge seat 1101 and a fourth hinge seat 1102. The third hinge seat 1101 and the fourth hinge seat 1102 are respectively vertically arranged on the outside of the fixed base 1201. Angle adjustment assemblies 17 are respectively provided on the third hinge seat 1101 and the fourth hinge seat 1102. The angle adjustment assembly 17 includes a third mounting plate 1701. A second motor 1702 is connected to the third mounting plate 1701. A shaft 1704 is provided at the bottom of the second motor 1702. The shaft 1704 is inserted into the third hinge seat 1101 and the fourth hinge seat 1102. A balance block 1703 is sleeved on the shaft 1704. An infrared emitter 1705 is provided on one side of the balance block 1703. The infrared emitter 1705 is used to lock the spray mark of the nozzle 1205. A replenishment bin 19 is also provided on the upper part of the spray assembly 12. The air pump 15 and the replenishment bin 19 are connected to the spray assembly 12 through the pipeline 20, respectively. The air pump 15 is connected to the pneumatic valve 18 through the pipeline 20. Two vertical infrared emitters 1705 work together. The second motor 1702 allows for easy adjustment of the illumination angle and position of the two infrared emitters 1705. The infrared emitters 1705 use beam strips and intersect at a point on the inner wall of the pit 1. When the intersection point is within the powder spraying range, the movement of the vibrating assembly 6 is checked and verified. After verification, the vibrating rod 609 is lowered for vibration operation. The air pump 15 uses airflow to open the pneumatic valve 18. At this time, the high-speed airflow carries the powder through the nozzle 1205 and sprays it onto the inner wall of the pit 1. The replenishment hopper 19 is equipped with an electrically controlled valve, which can replenish the fixed seat 1201 in a timely manner. After spraying is completed, the electronically controlled valve closes, and no powder remains in the fixed seat 1201. The overall operation is simple and ensures that the environment inside the fixed seat 1201 is relatively clean, resulting in good performance. At the same time, when the ranging module 14 obtains the distance to the inner wall of the pit 1 on one side, and when the detected distance exceeds the spraying range, the first motor 1602 rotates the first gear 1603, which in turn drives the second gear 1604 to rotate the second threaded rod 1605. The second threaded rod 1605 is threadedly connected to the second vertical plate 1207, which can drive the telescopic cylinder 1203 to change position. The overall operation is simple and the performance is good.
[0058] Working principle: This intelligent vibratory tamping device has two modes: automatic vibration and manual vibration. It is equipped with a control panel and a remote control. The control panel can be used to set parameters such as vibration time, vibration frequency, and cable winding and unwinding speed.
[0059] The remote control is simple and easy to operate, with 8 operation keys: automatic, manual, forward, backward, left, right, up, and down.
[0060] ①Dynamic vibration compaction process flow:
[0061] The operator presses the "Automatic" button to start the vibration device. The device automatically travels and positions itself to the vibration point. The vibrator 609 automatically lowers to the vibration height and automatically vibrates the concrete upon contact. After vibration at this point is completed, the vibrator 609 is lifted and travels to the next point to vibrate until all the concrete in this layer is vibrated. After vibration of this layer is completed, the vibrator 609 is returned to the zero position, and the next layer of concrete is vibrated according to the pouring situation.
[0062] ②Dynamic vibration compaction process flow:
[0063] Start the vibratory device. The operator presses the "Manual" button and, based on the real-time concrete pouring situation, uses the "Forward, Backward, Left, Right" buttons on the remote control to adjust the position of the vibrator 609. Lower the vibrator 609 to the set vibration point. The operator presses the "Down" button, and the vibrator 609 automatically vibrates after contacting the concrete at the set height. After vibration at this point is complete, the operator presses the "Up" button to lift the vibrator 609 and moves it to the next point for vibration until the entire layer of concrete is vibrated. After vibration of this layer is complete, the operator presses the "Up" button, and the vibrator 609 returns to the zero position. The next layer of concrete is then vibrated according to the pouring situation.
[0064] In a preferred embodiment, a construction method for an intelligent vibratory compaction device for the sidewalls of an open-cut tunnel includes the following steps:
[0065] S1. Install guide rails 5 on the upper part of the foundation pit 1, and then install a movable frame 3 between the two guide rails 5.
[0066] S2. Lock the mobile frame 3, and install the crossbeam 4, vibrating assembly 6, jacking assembly 7 and lifting beam 8 on the upper part of the mobile frame 3 respectively;
[0067] S3. Perform functional adjustments on the vibrating assembly 6 to ensure that the vibrator 609 works normally;
[0068] S4. Tie and fix the steel bars of tunnel segment 2 in the foundation pit 1, and then set up the formwork.
[0069] S5, the moving vibrating component 6, uses camera 13 to acquire top images between the reinforcing bars, screens and identifies gaps in the reinforcing bars and records them;
[0070] S6. Mark the starting and ending points of the reinforcing bars, and set the walking position of the vibrating component 6 according to the vibration step distance;
[0071] S7. When the project reaches a suitable vibration point, mark the side wall of the pit 1 using the spraying assembly 12.
[0072] S8. Use infrared emitter 1705 to lock the marked point of spray assembly 12, and then lower vibrator 609 to perform vibration operation.
[0073] S9. Repeat S4 to S8 until all tunnel segments 2 are poured.
[0074] In the preferred embodiment, initially, two vibrating components 6 are respectively installed on the crossbeams 4 on both sides of the movable frame 3.
