[0022] In this embodiment, the height adjustment structure includes multiple first hydraulic cylinders 2, the first hydraulic cylinders 2 are located on the lower side of the support frame 1, and the output end of the first hydraulic cylinder 2 is fixedly connected to the support frame 1. The downward pressure structure includes a second hydraulic cylinder 3, the second hydraulic cylinder 3 is fixedly connected to the support frame 1, and the output end of the second hydraulic cylinder 3 is fixedly connected to the downward pressure frame 4.
[0023] Specifically, by starting the first hydraulic cylinder 2, the support frame 1 can be driven up and down by the first hydraulic cylinder 2, thereby driving the second hydraulic cylinder 3 fixed on the support frame 1 to move up and down, thereby adjusting the height of the second hydraulic cylinder 3. By starting the second hydraulic cylinder 3, the lower pressure frame 4 can be driven to move, thereby assisting in drilling and achieving a better drilling effect. Moreover, when the first hydraulic cylinder 2 and the second hydraulic cylinder 3 work at the same time, the depth of the drilling can be increased, so that the device can drill deeper holes and expand the scope of application of the device.
[0024] The driving structure includes a motor 5 fixed in the lower pressure frame 4, a first gear 6 is fixed to the output end of the motor 5, a drilling tube 8 is rotatably connected to the lower pressure frame 4, a second gear 7 is fixed on the drilling tube 8, the second gear 7 is engaged with the first gear 6, and the drilling tube 8 is a tubular structure with openings at both ends.
[0025] Specifically, the motor 5 is started, so that the motor 5 drives the first gear 6 to rotate, so that the first gear 6 engages and rotates with the second gear 7, thereby driving the drilling tube 8 to rotate, and at the same time, the second hydraulic cylinder 3 is started to drive the drilling tube 8 to move downward, so that drilling can be carried out through the drilling tube 8, thereby facilitating subsequent grouting reinforcement. After the drilling is completed, the drilling tube 8 stays in the drilling tube 8, which can support the drill hole and prevent the drill hole from collapsing, thereby ensuring the success of grouting and thus ensuring the reinforcement effect.
[0026] A plurality of chip grooves 9 are provided on the circumferential side of the drilling tube 8, and the chip grooves 9 are spiral structures. The drainage structure includes a plurality of water inlet holes 21 provided on the circumferential side of the drilling tube 8, and the water inlet holes 21 are connected to the drilling tube 8. The crushing structure includes a crushing cutter head 23 fixed to the bottom of the drilling tube 8, and a drill bit 22 is fixed on the crushing cutter head 23, and a vibrating structure is fixed on the drill bit 22, and the vibrating structure corresponds to the grouting structure. The water inlet structure includes a water inlet pipe 11 provided in the fixed pipe 10, and the mud pumping structure includes a mud pumping pipe 12 provided in the fixed pipe 10, and the water inlet pipe 11 and the mud pumping pipe 12 are located on both sides of the grouting pipe 13. The fixed pipe 10 is an L-shaped structure, and a plurality of fixing rings 24 are fixed in the lower pressure frame 4, and the fixing ring 24 is fixedly connected to the fixed pipe 10.
[0027] Specifically, when the drilling tube 8 is drilling a hole, the drilling tube 8 rotates, which can drive the crushing cutter head 23 to rotate. At the same time, water is added through the water inlet pipe 11 connected to the water pump. On the one hand, the drilling tube 8 can be cooled, and on the other hand, it can be mixed with the mud in the drilling tube 8 to form mud. The mud can be pumped out by the mud pumping pipe 12 connected to the sewage pump, thereby preventing the mud from remaining in the borehole and facilitating subsequent grouting. After the drilling is completed, the drilling tube 8 remains in the borehole, so that the groundwater on the surrounding side can penetrate into the drilling tube 8 through the water inlet hole 21, and can be pumped out together through the mud pumping pipe 12, thereby reducing the impact of groundwater on grouting.
[0028] The grouting structure includes a grouting pipe 13 fixed in the fixed pipe 10, and a blocking plate 16 is installed at the bottom of the grouting pipe 13. The vibration structure includes a vibrating rod 20, and the vibrating rod 20 is fixedly connected to the drill bit 22. A friction plate 19 is fixed to the end of the vibrating rod 20, and the friction plate 19 corresponds to the blocking plate 16. Friction patterns are installed on the friction plate 19 and the blocking plate 16. A groove 14 is provided at the end of the grouting pipe 13, and a sliding frame 17 is slidably fitted in the groove 14. The sliding frame 17 is fixedly connected to the blocking plate 16. A plurality of springs 15 are fixed between the sliding frame 17 and the groove wall of the groove 14, and a plurality of through holes 18 are provided on the peripheral side of the sliding frame 17.
[0029] Specifically, when grouting is required, grouting is carried out through the grouting pipe 13. At this time, the larger pressure of the grouting pushes the blocking plate 16 downward, causing the sliding frame 17 to slide in the groove 14, and the spring 15 is stretched. After sliding to a certain distance, the friction plate 19 is in contact with the blocking plate 16, and the through hole 18 is connected to the outside. The slurry can flow out from the through hole 18, and grouting can be achieved. During grouting, the drilling tube 8 rotates and moves upward at the same time, so that the drilling tube 8 can be withdrawn from the drilling hole. At the same time, the rotation of the drilling tube 8 can drive the friction plate 19 to rotate together, so that the friction plate 19 and the blocking plate 16 rub against each other, causing the vibrating rod 20 to vibrate, which can achieve a better vibration effect, reduce bubbles in the slurry, and ensure the reinforcement effect.
[0030] Working process: start the motor 5, so that the motor 5 drives the first gear 6 to rotate, so that the first gear 6 and the second gear 7 are engaged and rotated, thereby driving the drilling tube 8 to rotate, and at the same time starting the second hydraulic cylinder 3 to drive the drilling tube 8 to move downward, and drilling can be performed through the drilling tube 8. When the drilling tube 8 is drilling, the drilling tube 8 rotates, which can drive the crushing cutter head 23 to rotate. At the same time, water is added through the water inlet pipe 11 connected to the water pump. On the one hand, the drilling tube 8 can be cooled, and on the other hand, it can be mixed with the mud in the drilling tube 8 to form mud, which can be pumped out by the mud pumping pipe 12 connected to the sewage pump, thereby preventing mud from remaining in the borehole and facilitating subsequent grouting. After the drilling is completed, the drilling tube 8 remains in the borehole, so that the groundwater on the surrounding side can pass through. It seeps into the drilling tube 8 through the water inlet hole 21, and can be extracted together through the mud extraction pipe 12. When grouting is performed, grouting is performed through the grouting pipe 13. At this time, the larger grouting pressure pushes the blocking plate 16 downward, causing the sliding frame 17 to slide in the groove 14, and the spring 15 is stretched. After sliding to a certain distance, the friction plate 19 contacts the blocking plate 16, and the through hole 18 is connected to the outside. The slurry can flow out from the through hole 18, and grouting can be achieved. During grouting, the drilling tube 8 rotates and moves upward at the same time, so that the drilling tube 8 can be withdrawn from the borehole. At the same time, the rotation of the drilling tube 8 can drive the friction plate 19 to rotate together, so that the friction plate 19 and the blocking plate 16 rub against each other, causing the vibrating rod 20 to vibrate, which can achieve a better vibration effect, thereby ensuring the reinforcement effect.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
