The screw 8 is threaded through the lifting plate 9. The lifting plate 9 is arranged between the two fixed plates 7. The top of the screw 8 is fixedly connected to the first motor 10; the vertical plate 6 is vertically fixed to the support plate 1, and a reinforcing plate 11 is also fixed between the support plate 1 and the vertical plate 6. The two fixed plates 7 are both vertically fixed to the vertical plate 6 and arranged up and down. Two guide rods 12 for preventing the lifting rod from being offset are fixedly connected between the two fixed plates 7. The lifting plate 9 slides through the two guide rods 12, and the screw 8 is driven to rotate by the first motor 10 to drive the lifting plate 9 to rise or fall. The drilling mechanism is arranged on the lifting plate 9. The drilling mechanism includes a drill rod 13, a sleeve 14 and a second motor 15. The drill rod 13 is abutted against the top of the sleeve 14 through a fixed block 19. When drilling downward, the drill rod 13 descends to drive the casing to move downward to protect the hole wall. The top of the drill rod 13 is connected to the second motor 15, which drives the drill rod 13 to rotate. The second motor 15 is arranged on the upper surface of the lifting plate 9, and the output end of the motor passes through the lifting plate 9. The drill rod 13 is arranged on the lower surface of the second motor 15. The lifting plate 9 moves downward to drive the drill rod 13 to drill downward; the outer wall of the sleeve 14 is sleeved with a positioning assembly, and the sleeve 14 can be vertically limited by the positioning assembly, thereby ensuring the verticality of the sleeve 14 and the drill rod 13 moving downward.

[0029] Specifically, the lifting plate 9 is provided with a through hole for penetrating the output end of the second motor 15, and a clip 16 for clamping the sleeve 14 is provided on the lower surface of the lifting plate 9. A bearing 17 capable of rotating up and down is connected between the clip 16 and the lifting plate 9. Figure 2 The buckle 16 is rotatably connected to the lifting plate 9 through the bearing 17, so that the buckle 16 can be adjusted in the circumferential direction. The buckle 16 is coaxially arranged with the through hole, and the inner diameter of the buckle 16 is larger than the diameter of the through hole, so that the second motor 15 can pass through downward. The buckle 16 includes a round tube 1601 and a plurality of L-shaped blocks 1602, see Figure 5 The top end of the round tube 1601 is rotatably connected to the lifting plate 9 , and a plurality of blocks 1602 are evenly distributed and fixedly connected to the bottom end of the round tube 1601 .

[0030] like Figure 3As shown, the top of the sleeve 14 is provided with a plurality of evenly distributed slots 18, the width of the block 1602 is smaller than the width of the slot 18, and the slot 18 is arranged in an inverted T shape, so that the sleeve 14 can abut against the drill rod 13, so that the drill rod 13 drives the sleeve 14 to move downward; and the buckle 16 can be engaged with the slot 18, and the sleeve 14 can be lifted upward under the drive of the lifting plate 9. The side wall of the drill rod 13 is fixedly connected with a plurality of circumferentially distributed fixing blocks 19, the width of the fixing blocks 19 is less than or equal to the width of the slot 18, and the number of the fixing blocks 19 is adapted to the number of the slots 18. When the drill rod 13 descends, the fixing blocks 19 correspond to the slots 18 one by one, and drive the sleeve 14 to move downward. The outer wall of the sleeve 14 is fixedly connected to a snap ring 20, which is disposed at the lower portion of the slot 18. The snap ring 20 is limited by a positioning assembly, and the positioning assembly limits the snap ring 20 to prevent the sleeve 14 from being buried in the soil.

[0031] like Figure 4 As shown, the positioning assembly includes a socket 21, a collar 22, a positioning plate 23 and an insertion rod 24 which are fixedly connected in sequence from top to bottom. The socket 21 is a bell-shaped structure with a larger top and a smaller bottom, so that the sleeve 14 can be quickly inserted downward into the soil under the guidance of the inclined side wall of the bell-shaped structure and remain vertical. The inner wall of the collar 22 is matched with the outer wall of the sleeve 14, so that the collar 22 vertically limits the sleeve 14. The positioning plate 23 is horizontally abutted against the soil. When the sleeve moves downward, the positioning plate 23 is driven to abut against the soil, and the insertion rod 24 is inserted into the soil at any time.

The first motor 10, the second motor 15 and the third motor 26 are all adapted to the controller. When it is inconvenient to connect to electricity outdoors, the controller and the power supply are equipped with a diesel generator for power supply. The stirring rod is controlled by the third motor 26 to mix the slurry in the storage box 4 to maintain the grouting quality.

[0033] The working principle of the drilling grouting device in this embodiment is: when in use, the drill rod 13 is connected to the second motor 15, the sleeve 14 is sleeved on the drill rod 13, the positioning assembly is set at the drilling position and sleeved with the sleeve 14, the grouting material is filled in the storage box 4, the first motor 10 and the second motor 15 are started, the second motor 15 drives the drill rod 13 to rotate and drill the soil, and the screw rod 8 rotates under the drive of the first motor 10 to drive the lifting plate 9 to move downward, so that the drill rod 13 drills downward. When the drill rod 13 drills downward, it abuts against the sleeve 14 and drives the sleeve 14 to move into the borehole, the clamping ring 20 is limited to the socket 21, so that the insertion rod 24 is inserted into the soil, and the positioning plate 23 abuts against the soil, thereby protecting the hole wall and the top of the hole. During grouting, the movable plate is lifted upward to disassemble the drill rod 13, and then the movable plate is lowered downward to lock the fastener 16 with the casing, open the valve at the bottom of the storage box 4, and insert the other end of the grouting pipe 25 into the sleeve 14. The grouting pipe 25 is made of flexible material, and one end close to the sleeve 14 is locked on the movable plate. As the movable plate is lifted upward, the grouting liquid is continuously injected into the hole, and the sleeve 14 is slowly pulled out until the grouting operation is completed.

[0034] In the drilling grouting device of this embodiment, due to the setting of the drill rod 13 and the sleeve 14, the fixed block 19 of the side arm of the drill rod 13 abuts against the sleeve 14, thereby driving the sleeve 14 to move downward, and is clamped to the sleeve 14 through the snap member 16. The grouting pipe 25 injects grout into the hole through the sleeve 14, and when the movable plate is lifted, the sleeve 14 is pulled out, thereby effectively protecting the hole, preventing the displacement or collapse of the soil body of the hole wall, and ensuring the quality of grouting reinforcement. Due to the setting of the positioning assembly, the outer wall of the sleeve 14 is fixedly connected with the clamping ring 20, which can fix the positioning assembly to the soil body when the drill rod 13 pushes the sleeve 14 to move downward, effectively ensuring the verticality of the drill hole, and at the same time preventing the soil body at the top of the hole from collapsing into the hole, improving the construction quality and work efficiency.
