[0002] The roadbed is the bearing foundation for the base and surface layers of the highway. The stability of the roadbed is an important condition for the stability of the road state. When the surface and base layers of the highway are compressed, the vertical load is transmitted to the roadbed, which will cause deformation of the roadbed. There is a risk of cracking in areas where the roadbed has large deformation. The cracked roadbed will affect the stability of the surface and base layers. Generally, cement slurry is poured into the cracks, and the compression and tensile strength of the roadbed is improved after the cement slurry is in contact with the roadbed soil and solidified.

[0034] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it. Example 1

[0035] See also Figure 1 or Figure 7The present embodiment provides a roadbed maintenance device, which includes a device body 100, the device body 100 includes a grouting pipe body 110, a connector 120 detachably arranged at the top wall of the grouting pipe body 110, and a vibrating assembly 130 detachably arranged at the bottom wall of the grouting pipe body 110, the grouting pipe body 110 has a conveying cavity for conveying cement slurry arranged along the length direction, a plurality of grouting grooves 210 connected to the conveying cavity are equidistantly formed on the outer wall of the grouting pipe body 110, and an auxiliary assembly 310 sliding along the length direction of the conveying cavity is arranged between the plurality of grouting grooves 210 and the conveying cavity; A downwardly recessed installation groove 330 is formed at the bottom wall of the conveying cavity. A conduction component for connecting the vibrating component 130 and the auxiliary component 310 is provided in the installation groove 330. The conduction component is used to transmit the vibration generated by the vibrating component 130 to the auxiliary component 310 to form reciprocating vibration inside the conveying cavity.

[0036] A roadbed maintenance device disclosed in the present invention is convenient for maintenance and replacement of the device through the setting of overall detachable splicing. By integrating the vibrating assembly 130 with the grouting pipe body 110 into one, the construction steps are reduced and the construction efficiency is improved. It is possible to perform vibration operation while conveying cement slurry in the gap, thereby improving the density of the mortar, and then improving the bonding between the mortar and the inner wall of the gap, avoiding the presence of bubbles in the cement slurry and the problem of vibrating it to make it dense after grouting with a vibrating rod.

[0037] In addition, through the cooperation of the auxiliary component 310 and the conduction component, the vibration component 130 drives the auxiliary component 310 to vibrate up and down while vibrating the mortar that has been poured into the gap, so that the mortar to be discharged inside the grouting pipe body 110 can be vibrated at the same time, thereby improving the fluidity of the discharge, thereby greatly improving the construction efficiency of the grouting.

[0038] See Figure 3 In this embodiment, the auxiliary component 310 includes a vibration plate 311 slidably disposed in the conveying cavity, and an extension portion cooperating with the plurality of pulp outlet grooves 210 is formed at the side wall of the vibration plate 311, and a vertical plate 313 is vertically disposed at the bottom of the extension portion, and a first slide groove 510 for the vertical plate 313 to slide is formed at the side wall of the pulp outlet groove 210, and the vertical plate 313 is used to form a seal for the pulp outlet groove 210; A downwardly recessed insertion groove 320 for the vertical plate 313 to be inserted into is formed at the bottom wall of the pulp outlet groove 210.

[0039] Through the above structure, under the action of the vibration of the vibrating component 130, the vibration is transmitted to the vibration plate 311 through the conduction component, so that the mortar to be discharged inside the grouting pipe body 110 is vibrated synchronously while the mortar poured into the gap is vibrated, thereby improving the fluidity of the discharged material, helping to eliminate bubbles in the cement slurry, improving the density, and promoting the penetration and diffusion of the cement slurry in the cracks.

[0040] The setting of the extension part can reciprocally clean the cement slurry at the slurry outlet groove 210 to avoid clogging of the slurry outlet groove 210.

[0041] It can be understood that the coordinated arrangement of the vertical plate 313, the slurry outlet groove 210 and the plug-in groove 320 enables the vertical plate 313 to form a seal for the cavity below the bottom of the vibration plate 311 that is connected to the slurry outlet groove 210, that is, the installation groove 330, to prevent cement slurry from entering the cavity, that is, the installation groove 330, through the slurry outlet groove 210 during further vibration, thereby causing damage to the conduction component.

[0042] See Figure 3 In this embodiment, an outer ring 312 is sleeved on the outer wall of the caulking tube body 110, and the outer ring 312 is fixed at the extension portion. A conical surface inclined from the axis toward the extension portion is formed on the top wall of the vibration plate 311.

[0043] Through the above structure, the outer ring 312 not only enhances the connection strength between the caulking pipe body 110 and the extension portion, but also improves the structural stability of the entire auxiliary component 310 .

[0044] In addition, the outer ring 312 also plays a guiding and limiting role, ensuring that the vibration plate 311 can slide along the length direction of the caulking tube body 110 during the vibration process.

[0045] It can be understood that, by providing the outer ring 312, the mortar outside the grouting pipe body 110 can be assisted in vibration while the vibration plate 311 vibrates, thereby further improving the efficiency of grouting.

[0046] The setting of the conical surface improves the fluidity of the cement slurry, thereby effectively reducing the amount of cement slurry remaining on the top of the vibration plate.

[0047] See Figure 1 or Figure 3 In this embodiment, the vibrating assembly 130 includes a vibrating rod 380 detachably disposed at the bottom wall of the caulking tube body 110. The vibrating rod 380 has an installation cavity inside, and an ultrasonic vibrator 370 is threadedly disposed in the installation cavity.

[0048] Through the above structure, the vibration rod 380 or the ultrasonic vibrator 370 can be easily installed and disassembled, and is convenient for maintenance and replacement. The ultrasonic vibrator 370 can generate ultrasonic vibrations, which have a higher frequency and stronger penetration, and can more effectively promote the flow and mixing of cement slurry, further improving the vibration effect. In addition, the noise pollution is small and the service life is long.

[0049] See Figure 2In this embodiment, a fixed tube 220 is coaxially arranged along the length direction of the caulking tube body 110 inside the conveying cavity, and a through cavity is provided inside the fixed tube 220 that passes through the connecting piece 120 and the bottom wall of the conveying cavity. A wire 230 for electrically connecting to the ultrasonic vibrator 370 is provided in the through cavity.

[0050] Through the above structure, the through cavity provides a safe channel for the wire 230, so that it can be introduced from the connecting piece 120 and extend along the inside of the fixed tube 220 to the ultrasonic vibrator 370 at the bottom wall of the conveying cavity, thereby reducing the risk of damage to the wire 230 and also reducing the volume of the vibration assembly 130.

[0051] In addition, the provision of the fixing tube 220 not only improves the overall structural strength of the caulking tube body 110 , but also serves as a guide for the cleaning piece 140 and the vibration plate 311 .

[0052] See Figure 5 In this embodiment, a convex portion 520 protruding upward and through openings 340 equidistantly arranged along the circumference of the convex portion 520 are formed at the bottom wall of the mounting groove 330; The conduction component includes a vibration guide 360 ​​that slides along the length direction of the outer wall of the protrusion 520. The vibration guide 360 ​​has a contact portion 610 that movably passes through the opening 340. The bottom of the contact portion 610 has an adhesive layer 620 connected to the ultrasonic vibrator 370. The top wall of the vibration guide 360 ​​is provided with a spring 350 for connecting to the vibration disk 311.

[0053] The through openings 340 are arranged equidistantly along the circumference of the protrusion 520 to ensure that the contact portion 610 on the vibration guide 360 ​​can be easily connected to the ultrasonic vibrator 370 through the through openings 340, so that the conduction component can more effectively transmit the vibration generated by the vibrating component 130 to the vibration disk 311.

[0054] The convex portion 520 is used as a sliding track for the vibration guide 360 ​​, thereby ensuring that the vibration guide 360 ​​can slide in a specific direction, thereby achieving effective vibration conduction.

[0055] The adhesive layer 620 may be made of a material with high adhesion to ensure the stability and reliability of the connection. The bonding also facilitates the installation and removal of the vibration assembly 130 .

[0056] See Figure 5 In this embodiment, an outwardly inclined inclined surface 530 is formed at the bottom wall of the slurry outlet groove 210 .

[0057] Through the above structure, the cement slurry at the bottom of the outer ring 312 and the side wall of the vertical plate 313 can be cleaned and flowed out through the inclined surface 530.

[0058] See Figure 7In this embodiment, the outer wall of the grouting tube body 110 also has a second slide groove 710 connected to the conveying cavity along the length direction, and the second slide groove 710 is slidably provided with a conveying pipe 720 for connecting to the hose at the output end of the cement slurry slurrying equipment.

[0059] Through the above structure, construction workers can move the delivery pipe 720 down to the ground after inserting the grouting pipe body 110 into the gap, so that it is suitable for gaps of different depths and further improves the construction efficiency of grouting. Example 2

[0061] Through the above structure, after the sealing is completed, the outer wall and inner wall of the caulking tube body 110 and the outer wall of the fixed tube 220 can be cleaned by reciprocating along the length direction of the caulking tube body 110. The cleaning effect is good and the operation is simple and fast, which not only improves the cleaning efficiency but also reduces the difficulty of operation.

[0062] During cleaning, the cleaning member 140 may be cleaned and rinsed with water at the same time to further improve the cleaning effect.

[0063] In addition, through the coordinated setting of the vibration disk 313 and the conduction component, when cleaning, the cleaning piece 140 can be moved down to fit with the vibration disk 313, and then the conduction component is driven by the vibrating component 130, and the vibration is transmitted to the vibration disk 313 through the conduction component to vibrate the cleaning piece 140 back and forth, thereby cleaning the cement slurry at the vibration disk 313 and the cleaning piece 140.

[0064] See Figure 2 or Figure 4 In this embodiment, a fastener 450 is provided at the end of the handle 440, and a hand-holding portion 150 is provided on both sides of the outer wall of the connecting member 120. A recess 240 which is recessed upward is formed at the bottom wall of the hand-holding portion 150, and a socket 160 which cooperates with the fastener 450 is provided at the side wall of the recess 240. The socket 160 is used to limit the fastener 450.

[0065] The hand-held portion 150 is disposed on both sides of the outer wall of the connecting member 120, providing a comfortable gripping point for construction workers.

[0066] At the same time, through the coordination of the holder 160 and the fastener 450, the cleaning member 140 can be limited when grouting to avoid interference with the grouting operation, and the cleaning member 140 can be released from the limit to perform the cleaning operation.
