After drilling, the roadbed is repaired by grouting through the grouting component 5. The slurry fills the gaps in the roadbed or base layer through diffusion and compaction, and combines with mineral materials with certain activity inside the road (such as soil, sand, stone, etc.) to form an inorganic gel, which ensures that the hidden problems of the roadbed or base layer are repaired in place without excavating the existing road.

The ground penetrating radar is used to detect the soil conditions in the roadbed or base layer. According to the design requirements, if a part that needs to be repaired is encountered, the feedback of the ground penetrating radar can realize the precise positioning of the subsequent drilling.

[0025] like Figure 1 As shown, the drilling assembly 3 includes a lifting member 4, a first motor 31 and a drill rod 32. The lifting member 4 includes a lifting motor 41, a lifting screw 42 and a lifting slider 43. A lifting slot is provided on the frame 1. The lifting motor 41 is fixedly connected to the frame 1. The lifting screw 42 is rotatably connected to the frame 1 and is located in the lifting slot. The axial direction of the lifting screw 42 is arranged along the gravity direction. A driving gear 411 is coaxially connected to the output shaft of the lifting motor 41. A transmission gear 48 is fixedly connected to the end of the lifting screw 42. The driving gear 411 is meshed with the transmission gear 48. The lifting slider 43 is threadedly connected to the lifting screw 42 and is located in the lifting slot.

[0027] During construction, the first motor 31 is first connected to the lifting slider 43, and the drilling construction of the roadbed is realized through the coordinated operation of the lifting motor 41 and the first motor 31. The drilling depth is set according to the feedback of the ground penetrating radar. After drilling, the first motor 31 is separated and disassembled from the lifting slider 43. The construction personnel assemble and connect the second clamping plate 54 with the lifting slider 43 to realize the installation of the grouting conduit 53. The lifting and lowering movement of the lifting slider 43 drives the grouting conduit 53 to move. At the same time, the pressure pump is operated to realize the grouting repair and reinforcement in the hole.

[0028] like Figure 3 and 4 As shown, in order to facilitate monitoring and observing the road conditions during the grouting stage, the equipment also includes a horizontal stabilizer 6, which includes a connecting rod, a stabilizing plate 61 and a level detector. A sliding groove 12 is provided on the frame 1, and a matching rod 7 is slidably connected in the sliding groove 12. The stabilizing plate 61 is an annular plate, which is connected to one end of the connecting rod. The side of the stabilizing plate 61 away from the frame 1 is attached to the road surface, and the connecting rod and the stabilizing plate 61 are provided with a drill rod 32 or a grouting conduit 53. The level detector is built into the stabilizing plate 61, and the level detector is used to detect the arching of the road surface. A clamping block 66 is fixedly connected to one end of the connecting rod away from the stabilizing plate 61, and the clamping block 66 is clamped on the matching rod 7 to realize the installation connection of the connecting rod.

[0029] like Figure 1 and 4 As shown, the matching rod 7 and the detection plate 21 are connected by a connecting belt 8, and a matching pulley 11 is rotatably connected to the frame 1, and the connecting belt 8 abuts against the matching pulley 11. A magnetic block 1 is provided in the sliding groove 12, and a magnetic block 2 is provided at the end of the matching rod 7 and one end located in the sliding groove 12, and the magnetic block 1 is magnetically connected to the magnetic block 2. During the detection construction stage, the detection plate 21 is extended to facilitate the operation of the ground penetrating radar. After the positioning is completed, the construction personnel push the detection plate 21 to slide, driving the matching rod 7 to move along the sliding groove 12 until the magnetic block 1 and the magnetic block 2 are magnetically connected, and the matching rod 7 is fixed, thereby facilitating the subsequent installation of the connecting sleeve rod.

[0030] like Figure 4As shown, in order to make the height of the connecting sleeve rod suitable for various road conditions, the connecting sleeve rod is set to be retractable. The connecting sleeve rod includes a plurality of connecting ring plates 62, and each single connecting ring plate 62 is provided with a telescopic slide 63 and a telescopic clamping groove 64 along the axial direction. The telescopic clamping groove 64 is connected to the telescopic slide 63, and the telescopic clamping groove 64 is not coaxial with the telescopic slide 63. The telescopic clamping groove 64 is provided on the right side of the telescopic slide 63. A telescopic clamping block 65 is fixedly connected to each single connecting ring plate 62, and the telescopic clamping block 65 is clamped into the telescopic slide 63 of the adjacent connecting ring plate 62. The plurality of connecting ring plates 62 are connected in sequence, and the diameters of the plurality of connecting ring plates 62 are successively reduced along the axial direction. In this embodiment, the connecting ring plate 62 with the smallest diameter is fixedly connected to the stabilizing plate 61, and the clamping block 66 is provided on the connecting ring plate 62 with the largest diameter.

[0031] When in use, the construction worker lifts the connecting ring plate 62 with the largest diameter and rotates it to the left, driving the telescopic clamping block 65 to move along the telescopic slide groove 63 and move into the telescopic clamping groove 64. According to actual construction needs, it can be stopped after it is extended to the use height. After the construction is completed, when storing, the clamping block 66 is separated from the matching rod 7, and then the connecting ring plate 62 is rotated in the opposite direction, so that several connecting ring plates 62 are overlapped in sequence, and the smaller diameters are moved in sequence to the inside of the connecting ring plate 62 with the largest diameter to achieve storage.

[0032] After assembly, the stabilizing plate 61 fits the road surface, and the grouting conduit 53 is inserted into the hole. Under the action of the pressure pump, the slurry is poured into the hole to perform targeted repair and reinforcement on the roadbed or base. During the grouting process, the level detector in the stabilizing plate 61 always monitors the road surface arching. If the road surface arches and deforms during the construction process, the level detector immediately gives feedback, and the level detector model is selected according to the actual construction needs. After receiving the feedback, the construction personnel immediately suspend the construction and make adjustments to minimize the damage to the surrounding good roads during the construction process.

[0033] The implementation principle of a trenchless road repair grouting reinforcement device in the embodiment of the present application is: The device is driven to move on the road to be repaired by a traction device, and the ground penetrating radar detects and locates the roadbed or base layer. Then, the first motor 31 and the drill bit 33 are assembled and connected, and a small range of holes are drilled on the roadbed or base layer under the cooperation of the lifting motor 41 and the first motor 31. After the drilling is completed, the grouting conduit 53 is connected to the lifting slider 43 by the second clamping plate 54 to realize the trenchless grouting reinforcement construction.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
