[0046] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0047] See also Figure 1 and Figure 2 , the present invention discloses a bridge tunnel grouting device, which is used for grouting a gap 810 in a soil layer 800, and includes a cart 100 and a grout storage tank 200 arranged on the cart 100;

[0048] See also Figure 3 and Figure 4 A groove 110 is provided at the front end of the cart 100, a slide rail 300 is horizontally installed in the groove 110, and the extension direction of the slide rail 300 is perpendicular to the forward direction of the cart 100; a sliding member 400 is slidably installed in the slide rail 300, and a path guide member 500 and a grouting member 600 are respectively provided on the sliding member 400, and the grouting member 600 is located on the side of the path guide member 500 away from the slide rail 300;

[0049] See also Figure 6 , Figure 7 and Figure 8 The path guide 500 includes a sleeve 510 rotatably mounted on the sliding member 400 and a guide column 520 detachably connected to the sleeve 510, a mounting plate 550 is provided on the guide column 520, and a guide ring 560 is rotatably mounted on the outer side of the mounting plate 550;

[0050] During the grouting process, the guide column 520 is inserted into the gap 810 of the soil layer 800, and the cart 100 moves forward along the gap 810. When the extension direction of the gap 810 deviates from the forward direction of the cart 100, the guide ring 560 on the guide column 520 rolls in contact with the inner wall of the gap 810, thereby adjusting the forward direction of the guide column 520, so that the guide column 520 is fed according to the extension path of the gap 810, and at the same time drives the sliding member 400 to slide adaptively in the slide rail 300, so that the grouting route of the grouting member 600 coincides with the extension path of the gap 810.

[0051] Specifically, the grouting material is stored in the grout storage tank 200, the cart 100 is pushed to the top of the gap 810 to be grouted, the guide column 520 and the sleeve 510 are assembled, the guide column 520 is vertically inserted into the gap 810, and the cart 100 is driven to feed forward along the extension direction of the gap 810. The guide column 520 moves forward along the gap 810 synchronously under the drive of the cart 100. When the extension direction of the gap 810 at the position of the guide column 520 deviates from the forward direction of the cart 100, the guide ring 560 on the guide column 520 can be aligned with the gap 810. 0 contacts the inner wall of one side of the slit 810 and rolls forward along the inner wall of the slit 810, so that the moving path of the guide column 520 is consistent with the extension path of the slit 810, and at the same time, the sliding member 400 also follows the guide column 520 to slide adaptively to one side in the slide rail 300. Since the path guide member 500 and the grouting member 600 are relatively fixed, the guide column 520 can be used to guide the moving path of the grouting member 600, so that the moving path of the grouting member 600 is consistent with the extension path of the slit 810, thereby avoiding the grouting failure caused by the misalignment of the grouting member 600 and the slit 810.

[0052] It is worth noting that the path guide 500 in the present invention can trigger the sliding member 400 to produce an adaptive offset along the slide rail 300 according to the extension path of the gap 810, thereby changing the moving path of the grouting member 600, so that the moving path of the grouting member 600 is always consistent with the extension path of the gap 810, avoiding the grouting failure caused by the misalignment of the grouting member 600 and the gap 810.

[0053] In one embodiment, see Figure 5 The sliding member 400 includes a slide table 410 movably disposed in the slide rail 300 and a mounting plate 420 integrally connected to the slide table 410. The path guide 500 and the grouting member 600 are both mounted on the mounting plate 420. A roller 430 that is in rolling contact with the slide rail 300 is rotatably mounted on the slide table 410.

[0054] When the path guide 500 moves along the path extending from the gap 810 , it drives the roller 430 on the slide 410 to roll along the slide rail 300 accordingly, so that the slide 410 is adaptively offset;

[0055] Considering that when the guide column 520 moves along the gap 810, the foreign matter such as gravel in the gap 810 will affect the normal passage of the guide column 520, and will affect the normal filling of the gap 810 by the grouting material in the subsequent grouting process, it is necessary to clean the foreign matter along the gap 810; accordingly, please refer to Figure 5 and Figure 6A driving motor 440 for driving the sleeve 510 is fixedly mounted on the mounting plate 420, a limiting clamping strip 530 engaged with the sleeve 510 is disposed at the upper end of the guide column 520, and a plurality of cleaning sheets 540 are circumferentially disposed at the lower end of the guide column 520;

[0056] Specifically, when the cart 100 moves forward, the drive motor 440 drives the sleeve 510 and the guide column 520 to rotate synchronously, thereby driving the cleaning sheet 540 to rotate circumferentially to clean foreign objects along the gap 810;

[0057] It should be noted that in order to ensure the cleaning effect, the operating radius of the cleaning sheet 540 should be larger than the outer ring radius of the guide ring 560. Accordingly, in order to avoid the cleaning sheet 540 from colliding with the inner wall of the gap 810 and causing damage to the cleaning sheet 540, the cleaning sheet 540 can be made of flexible materials such as rubber, as long as it can achieve the effect of cleaning foreign matter inside the gap 810, and even if it contacts the inner wall of the gap 810, it will not cause damage to the cleaning sheet 540.

[0058] In yet another embodiment, see Fig. 9 The grouting member 600 includes a rigid tube 610 fixedly mounted on a mounting plate 420, a connector 620 is provided at the lower end of the rigid tube 610, a grouting cover 630 is rotatably mounted on the connector 620, a grouting tube 640 is provided at the lower end of the grouting cover 630, and a plurality of grouting outlets 641 are symmetrically opened on both sides of the grouting tube 640; a grouting pump 670 for pumping grouting material into the rigid tube 610 is installed on the mounting plate 420, and the grouting pump 670 is connected to the grouting tank 200 through a grouting pipe 680;

[0059] Specifically, when filling the gap 810, the grouting pipe 640 is inserted into the gap 810, and the grouting material in the grout storage tank 200 is drawn out through the grouting pipe 680 and pumped into the rigid pipe 610 by the grouting pump 670, and then the grouting material enters the grouting pipe 640 through the grouting cover 630 and is squeezed out from each grout outlet 641, so as to achieve filling of different parts in the gap 810;

[0060] It should be noted that, in order to enable the grouting pipe 640 to adapt to the slit 810 bent in different directions, the grouting pipe 640 can be made of a flexible material, such as silicone, so that it can change its shape accordingly according to the contour of the slit 810, ensuring that the grouting material can penetrate into different positions of the slit 810 to avoid hollowing.

[0061] In addition, the grouting cover shell 630 can rotate circumferentially relative to the rigid tube 610 so that the grouting cover shell 630 can be deflected accordingly according to the extension path of the gap 810, so that the grouting tube 640 below can fit better with the gap 810.

[0062] Furthermore, if the grouting material cannot quickly sink into the cavity below the gap 810 during the grouting process, not only will the cavity below the gap 810 be hollowed out, but the grouting material poured into the gap 810 will overflow from the upper opening of the gap 810. For this reason, please refer to Fig.10 A vibrating rod 650 is installed on the grouting shell 630, and the vibrating rod 650 is located on the side of the grouting pipe 640 away from the path guide 500; an anti-overflow cover 660 is arranged on the periphery of the grouting shell 630, and the lower end surface of the anti-overflow cover 660 is in contact with the upper end surface of the soil layer 800;

[0063] When the grouting member 600 moves forward as a whole along the extension path of the gap 810, the overflow cover 660 is always in contact with the upper end surface of the soil layer 800. When the grouting pipe 640 pours grouting material into the gap 810, the vibrating rod 650 on the rear side thereof vibrates the filled grouting material at the same time, so that the grouting material quickly penetrates into the lower cavity of the gap 810, and at the same time, the air inside the grouting material is discharged to avoid hollowing. When part of the grouting material overflows from the opening at the upper end of the gap 810, the overflowed grouting material is still in the space enclosed by the overflow cover 660. The overflowed grouting material is pushed and scraped forward by the forward-moving overflow cover 660, thereby preventing the grouting material from being retained on the upper end surface of the soil layer 800 and affecting the flatness of the soil layer 800. At the same time, the overflowed grouting material can flow into the gap 810 in front again to avoid wasting grouting material.

[0064] In a further embodiment, to further improve the grouting effect, please refer to Figure 5 and Fig.11 The mounting plate 420 is also provided with a slotted member 700, the slotted member 700 is located on a side of the path guide member 500 away from the grouting member 600, the slotted member 700 includes a mounting frame 710 fixed on the mounting plate 420, a slotted disk 730 is rotatably mounted on the lower end of the mounting frame 710, the slotted disk 730 is symmetrically provided with conical surfaces on both sides, a grinding sheet 740 is mounted on the conical surface, the grinding sheet 740 is used to grind the upper end opening of the gap 810 to form a V-shaped notch; the mounting frame 710 is also provided with a driving member for driving the slotted disk 730;

[0065] See also Figure 5 and Fig.11 The driving member includes a rotating shaft 720 coaxially fixedly connected to the slotted disk 730 and a second transmission shaft 760 horizontally rotatably mounted on the mounting frame 710, and the rotating shaft 720 and the second transmission shaft 760 are connected to each other through a second transmission belt 770;

[0066] A first transmission shaft 750 is vertically rotatably mounted on the mounting plate 420, and the first transmission shaft 750 is transmission-connected to the output end of the driving motor 440 via a first transmission belt 450; a first bevel gear 751 is disposed at the lower end of the first transmission shaft 750, and a second bevel gear 761 meshing with the first bevel gear 751 is disposed at one end of the second transmission shaft 760 away from the second transmission belt 770;

[0067] Specifically, the driving motor 440 drives the first transmission shaft 750 to rotate through the first transmission belt 450 while driving the path guide 500 to rotate. Under the meshing transmission of the first bevel gear 751 and the second bevel gear 761, the second transmission shaft 760 can be driven to rotate, and then under the transmission of the second transmission belt 770, the rotating shaft 720 and the slotted disk 730 are driven to rotate, and the grinding sheets 740 on both sides of the slotted disk 730 are used to grind and cut the two sides of the upper end opening of the gap 810, so as to form a V-shaped notch, which can make the grouting material and the soil layer 8 00 increases, thereby improving the adhesion and density between the grouting material and the soil layer 800, which helps to enhance the overall stability and anti-seepage performance of the soil layer 800; the V-shaped notch can also guide the grouting material to penetrate deeper into the gap 810, ensuring that the grouting material can fully fill the gap 810 and improve the grouting effect; and the V-shaped notch is relatively easy to clean, and can more thoroughly remove debris and loose materials at the opening of the gap 810, reduce the possibility of grouting material loss under pressure, and ensure that the grouting material is fully solidified in the gap 810.

[0068] Furthermore, considering that a large amount of soil fragments will be splashed during the grooving process, the splashed soil fragments will not only contaminate the grouting material of the rear grouting filling, but also the soil fragments will be scattered around the V-shaped notch, affecting the normal passage of the path guide 500. For this reason, please refer to Fig.12 A splash shield 780 is provided on one side of the slotted disk 730 close to the path guide 500, and the splash shield 780 is fixedly mounted on the mounting frame 710; an annular cavity 731 is provided in the slotted disk 730, and a plurality of blowing holes 732 connected to the annular cavity 731 are provided circumferentially on the slotted disk 730, a sealing cover 792 is fixed on one side of the mounting frame 710, and an air passage 733 connecting the annular cavity 731 and the sealing cover 792 is axially provided on the slotted disk 730, and a sealing ring 734 is provided at the rotational connection between the air passage 733 and the sealing cover 792;

[0069] See also Figure 3 , an air pump 790 is installed on the cart 100, and the output end of the air pump 790 is connected to the sealing cover 792 through an air pipe 791;

[0070] Specifically, when the slotting disc 730 rotates to slot, the splashing debris is blocked by the splash shield 780 to prevent the debris from contaminating the grouting material at the rear side. At the same time, the air pump 790 blows air into the sealing cover 792 through the air pipe 791, and the gas enters the annular cavity 731 through the air channel 733 and is blown out from each blowing hole 732, thereby blowing the debris cut off by the slotting disc 730 away from the V-shaped notch, preventing the debris from being retained around the V-shaped notch and affecting the grouting operation.

[0071] It should be noted that the gas blown out of the blowing hole 732 changes the direction of the airflow due to the blocking effect of the splash guard 780, so that the splashing gravel can be blown away in the forward direction, avoiding the gravel from being retained on the end face of the V-shaped notch, making the formed V-shaped notch smoother, which is conducive to subsequent grouting operations.

[0072] It is worth noting that in order to make the subsequent grouting cover 630 better fit with the V-shaped notch, the grouting cover 630 is symmetrically provided with wedge-shaped surfaces fitting with the V-shaped notch on both sides, and a recessed portion 631 is provided on the wedge-shaped surface, and a plurality of pressure rollers 632 rollingly fitting with the V-shaped notch are rotatably installed in the recessed portion 631;

[0073] When the grouting member 600 moves forward along the extension path of the gap 810, the pressure rollers 632 on the wedge-shaped surfaces on both sides of the grouting cover 630 roll in contact with the end faces of the V-shaped notch, which not only reduces the resistance during the movement of the grouting cover 630, but also allows the pressure rollers 632 to roll the V-shaped notch to make the surface of the V-shaped notch smoother and avoid collapse of the V-shaped notch, while also guiding the grouting material to penetrate into the gap 810 more stably.

[0074] In yet another embodiment, see Fig.13 and Fig.14 The slurry storage tank 200 includes an outer shell 201 and an inner shell 202 disposed in the outer shell 201, and a slurry discharge pipe 203 connected to the slurry delivery pipe 680 is disposed at the bottom of the inner shell 202; a mixing motor 210 is installed on the cart 100, and a mixing shaft 220 vertically penetrated into the inner shell 202 is connected to the output end of the mixing motor 210, and a plurality of first paddles 230 are circumferentially disposed on the mixing shaft 220, and a second paddle 240 extending into the slurry discharge pipe 203 is connected to the first paddle 230, and a plurality of through holes 250 are opened on the first paddle 230 and the second paddle 240;

[0075] Specifically, the grouting material is stored in the inner tank 202 of the slurry storage tank 200, and the mixing shaft 220 is driven to rotate by the mixing motor 210, thereby driving the first paddle 230 and the second paddle 240 to rotate, so as to continuously mix the grouting material to avoid stratification and sedimentation of the grouting material, while ensuring the fluidity of the grouting material.

[0076] The specific implementation methods of this embodiment are described above, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms inspired by this embodiment, all of which are within the protection of this embodiment.
