[0002] When repairing a leaking wall, a drilling device is first used to drill grouting holes in the area of ​​the wall corresponding to the leak, and then a grouting device is used to inject grout into the holes. Currently, the grouting device includes a grouting pipe, which is connected to a liquid pump via a pipeline. Before grouting the wall, a corresponding tubular seal is inserted into the grouting hole using a corresponding tool. This seal seals the gap between the grouting pipe and the hole wall during the subsequent grouting process.

[0003] However, the traditional drilling and grouting process relies on manual operation, and the hole diameter and hole depth drilled by the drilling device are prone to deviations. During the subsequent insertion of the seal, the specifications of the seal are not suitable for the hole diameter of the grouting hole, and gaps are prone to occur. As a result, the grouting process does not reach the rated pressure, and the slurry flows out of the grouting hole, affecting the quality of the grouting and reducing the effect of the wall repair.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1, as Figure 1-Figure 7 and Figure 9A wall drilling and grouting device for building construction includes a mounting base 1, which is used to carry a drilling and grouting assembly. The mounting base 1 is installed on a horizontal linear guide rail module supporting a lifting platform, so that the mounting base 1 can adjust its height and horizontal position. For example, the supporting lifting platform is configured as a working trolley, and a lifting base is provided on the working trolley. The lifting base is driven up and down by an electric push rod. When the working trolley drives the mounting base 1 to move to the working position, the horizontal linear guide rail module drives the mounting base 1 to move horizontally, which is used to switch the corresponding positions of the drilling assembly, the grouting assembly and the wall. For example, the horizontal linear guide rail module is configured as a lead screw and a linear guide rail driven by a motor, and the lead screw transmission drives the mounting base 1 to move along the linear guide rail.

[0020] A No. 1 movable seat 2 is slidably provided on one side of the top of the mounting seat 1, and a drilling mechanism 3 is fixedly provided on the top of the No. 1 movable seat 2. The No. 1 movable seat 2 is driven by an electric push rod to move horizontally relative to the mounting seat 1 to adjust the distance between the drilling mechanism 3 and the wall. The drilling mechanism 3 is used to drill holes in the wall. For example, the drilling mechanism 3 can be set as a drill barrel driven by a motor. A No. 2 movable seat 4 is slidably provided on one side of the top of the mounting seat 1. The No. 2 movable seat 4 is driven by an electric push rod to move horizontally relative to the mounting seat 1. A grouting pipe 5 is fixedly provided on the top of the No. 2 movable seat 4. The grouting pipe 5 is connected to the liquid pump through a pipeline. Figure 4 A partition plate 13 is fixedly sleeved on one side of the grouting pipe 5. The partition plate 13 is provided with a through hole for the slurry to pass through. A control valve is provided on the through hole to control the opening and closing of the through hole.

[0021] A sealing sleeve 6 is provided on one side of the grouting pipe 5, and a flexible pad 7 is provided on one side of the sealing sleeve 6. The sealing sleeve 6 is used to cooperate with the flexible pad 7 to seal the gap between the grouting pipe 5 and the grouting hole. A movable sleeve 16 is provided on one side of the sealing sleeve 6. The movable sleeve 16 is located on one side of the flexible pad 7 and is used to cooperate with one end face of the sealing sleeve 6 to clamp the two ends of the flexible pad 7. A movable sleeve 12 is threaded on one side of the outer side of the sealing sleeve 6. The movable sleeve 12 can be screwed into the side close to the flexible pad 7 by rotating. Figure 6 The outer wall of the movable sleeve 12 is a regular polygon, and the outer side of the movable sleeve 12 is slidably sleeved with a rotating ring 9. The inner wall shape of the rotating ring 9 is adapted to the outer wall shape of the movable sleeve 12. The rotating ring 9 drives the movable sleeve 12 to rotate while the movable sleeve 12 can move axially relative to the rotating ring 9.

[0022] A movable block 19 is provided on one side of the wall of the grouting pipe 5. Figure 7The movable block 19 can be inserted into the end of the sealing sleeve 6 and slidably connected to the sealing sleeve 6. The movable block 19 is used to limit the rotation of the sealing sleeve 6 relative to the grouting pipe 5. The inner tube 14 is fixedly connected to the middle position of the No. 1 partition 13. The No. 2 partition 15 is fixedly connected to one side of the sealing sleeve 6. The No. 2 partition 15 is provided with a through hole for the passage of slurry. The number of through holes corresponding to the No. 2 partition 15 is set to a number, see Figure 5 A shrinkage bag 21 is provided on one side of the wall of the inner tube 14. The shrinkage bag 21 has a tendency to shrink. A sliding block 22 is provided on one side of the sliding sleeve of the inner tube 14. The number of sliding blocks 22 is set to at least one. The sliding blocks 22 are arranged at the outer side of the inner tube 14 in a uniformly spaced manner. The side of the sliding block 22 away from the axis of the inner tube 14 is an inclined surface. The sliding block 22 is used to limit the axial movement of the No. 2 partition 15 away from the grouting pipe 5, thereby limiting the axial movement of the sealing sleeve 6 in the corresponding direction relative to the grouting pipe 5.

[0023] The sliding block 22 is located on one side of the inner tube 14 and is slidably connected to a connecting rod 23. The connecting rod 23 is T-shaped. The connecting rod 23 can move radially relative to the sliding block 22 in the inner tube 14 without separating from the sliding block 22. One end of the connecting rod 23 is fixedly connected to the shrinkage bag 21, and the end of the connecting rod 23 close to the axis of the inner tube 14 is slidably sleeved with a fixed block 24. The fixed block 24 is fixedly connected to the inner tube 14. A spring is provided between the fixed block 24 and the sliding block 22. The spring is used to push the sliding block 22 out of the inner tube 14. The shrinkage bag 21 can overcome the spring force corresponding to the sliding block 22 to drive the sliding block 22 to shrink into the inner tube 14, and the No. 2 partition 15 is movably sleeved with the inner tube 14.

[0024] When the cam 16 is in the state of being threadedly sleeved with the sealing sleeve 6, the movable ring 16 and the sealing sleeve 6 cooperate to be in the state of clamping the flexible pad 7. At this time, the flexible pad 7 remains flat, and the sealing sleeve 6 is sleeved on the grouting pipe 5 in advance, so that the movable block 19 is sleeved with the sealing sleeve 6, and the sealing sleeve 6 and the end face of the grouting pipe 5 form a seal. At this time, the rotating ring 9 and the movable sleeve 12 are sleeved together. During the sleeve connection process of the sealing sleeve 6, the sealing sleeve 6 drives the second partition 15 to sleeve on the outer side of the inner tube 14. When the second partition 15 contacts the inclined surface of the sliding block 22, the sliding block 22 is driven to overcome the corresponding spring force to retract toward the inner tube 14 until the sealing sleeve 6 is sleeved in place. At this time, the second partition 15 is out of contact with the sliding block 22, and the corresponding spring pushes the sliding block 22 to extend. The sliding block 22 limits the axial movement of the second partition 15 relative to the grouting pipe 5 to complete the pre-sleeving of the sealing sleeve 6, thereby simplifying the installation steps of the seal, improving the efficiency of the overall grouting, and saving manpower.

[0025] Adjust the mounting seat 1 to the corresponding position, drive the drilling mechanism 3 close to the wall, and drill the grouting hole on the wall. After the drilling is completed, drive the drilling mechanism 3 to break away from the contact with the wall, adjust the horizontal position of the mounting seat 1, and the mounting seat 1 drives the grouting pipe 5 to move and switch the corresponding position of the grouting pipe 5, so that the axis of the grouting pipe 5 is collinear with the axis of the grouting hole. The No. 2 moving seat 4 moves close to the wall through the electric push rod, and the No. 2 moving seat 4 drives the grouting pipe 5 close to the wall. The transmission drives the end of the sealing sleeve 6 to insert the rated length into the grouting hole, rotate the rotating ring 9, and the rotating ring 9 rotates with The movable sleeve 12 rotates, and the movable sleeve 12 rotates and screws in relative to the sealing sleeve 6. When it is screwed into place, the movable sleeve 12 is disengaged from the rotating ring 9. The movable sleeve 12 is screwed in and drives the movable ring 16 to approach the end of the sealing sleeve 6. The movable ring 16 cooperates with the sealing sleeve 6 to squeeze the flexible pad 7, so that the middle part of the flexible pad 7 is arched, thereby increasing the sealing pressure of the flexible pad 7 and expanding the sealing diameter of the flexible pad 7, so that the flexible pad 7 can form a seal with the irregular grouting hole on the inner wall and the grouting pipe 5, simplifying the sealing steps while improving the sealing effect and improving the reliability of the drilling grouting device.

[0026] A sealing block 20 for sealing the corresponding through hole is slidably sleeved on one side of the No. 2 partition 15. The position of the sealing block 20 corresponds to the through hole of the No. 2 partition 15. A spring is fixedly connected between the sealing block 20 and the end of the sealing sleeve 6. The spring corresponding to the sealing block 20 is used to push the sealing block 20 close to the No. 2 partition 15 to block the corresponding through hole. After the sealing is completed, the control valve corresponding to the No. 1 partition 13 is opened, and the slurry is extracted by the liquid pump through the grouting pipe 5 through the through hole corresponding to the No. 1 partition 13. The slurry overcomes the elastic force of the spring corresponding to the sealing block 20 and pushes the sealing block 20 away from the corresponding through hole. The slurry enters the grouting hole through the gap between the sealing block 20 and the sealing sleeve 6 until the pressure of the pumped slurry reaches the rated value and the slurry flows out through the leaking gaps in the wall. The grouting is completed, the pumping of the slurry is stopped, the control valve is closed, and the sealing block 20 closes the through hole of the No. 2 partition 15 under the push of the corresponding spring to prevent the slurry from flowing back when the grouting pipe 5 is withdrawn from the grouting hole.

[0027] A gas cylinder 30 is fixedly provided on one side of the second movable seat 4. Figure 9 A vent hole 33 is provided on one side of the cylinder 30, a sliding plug 31 is slidably provided on the inner side of the cylinder 30, an air inlet pipe 34 is fixedly provided on the other side of the cylinder 30, an air outlet pipe 35 is fixedly provided on one side of the cylinder 30, and a one-way valve is fixedly provided on the air inlet pipe 34 for gas to enter the cylinder 30 in one direction through the air inlet pipe 34, see Figure 4A connecting pipe 37 is fixedly connected to one side of the inner tube 14, and the air outlet pipe 35 is connected to the connecting pipe 37 through a pipeline. A pressure relief pipe 36 is fixedly connected to one side of the inner tube 14, and a solenoid valve is fixedly provided on the pressure relief pipe 36. The tube hole of the inner tube 14 is connected to the cavity of the contraction bag 21. The air inlet pipe 34 and the air outlet pipe 35 are located on one side of the sliding plug 31, and the vent hole 33 is located on the other side of the sliding plug 31.

[0028] After the grouting is completed, the solenoid valve opens, the contraction bag 21 contracts, and the contraction bag 21 drives the connecting rod 23 to move, and the connecting rod 23 drives the sliding block 22 to move and shrink into the inner tube 14, and the limit of the No. 2 partition 15 is removed. The No. 2 moving seat 4 moves to drive the grouting pipe 5 to exit the grouting hole, and the grouting is completed. The sliding plug 31 is controlled by the driving component to move to the side close to the air outlet pipe 35, and the rated amount of gas is filled into the contraction bag 21. The contraction bag 21 expands, and cooperates with the movement of the connecting rod 23 to remove the pull on the sliding block 22. The spring corresponding to the sliding block 22 drives the sliding block 22 to reset.

[0029] Example 2, as Figures 1-10 On the basis of the first embodiment, one end of the air cylinder 30 is fixedly connected to a guide rod 28 at the midpoint, and an adjusting rod 25 is slidably sleeved on the outer side of the guide rod 28. The rod body of the adjusting rod 25 is provided with a spiral adjusting groove 26. A transmission mechanism 8 is provided on one side of the second moving seat 4. The transmission mechanism 8 includes an external gear 801 and a ratchet gear 802. The ratchet gear 802 and the external gear 801 are both rotatably connected to the second moving seat 4. Figure 8 A stop pawl 803 is provided on the inner side of the outer gear 801 for rotation, and a spring is fixedly connected between the stop pawl 803 and the outer gear 801. The stop pawl 803 cooperates with the corresponding spring to enable the ratchet gear 802 to drive the outer gear 801 to rotate in one direction. An adjustment block 27 is fixedly connected to the inner side of the ratchet gear 802, and the adjustment block 27 is slidably connected to the adjustment slot 26. A contact switch 29 is fixedly provided on one end of the guide rod 28 close to the air cylinder 30, and the contact switch 29 is electrically connected to the solenoid valve of the pressure relief pipe 36. A spring is movably provided on the side of the sliding plug 31 close to the air intake pipe 34.

[0030] One side of the sliding plug 31 is fixedly connected to a moving rod 32, and the moving rod 32 extends out of the air cylinder 30 with the rod body. The number of the moving rod 32 is set to at least one, and the moving rod 32 is fixedly connected to the adjusting rod 25. A connecting gear 11 is rotatably provided on one side of the grouting pipe 5, and a transmission ring 10 is fixedly connected to one side of the connecting gear 11. A transmission key 18 is fixedly provided on the inner side of the transmission ring 10, and the transmission ring 10 is slidingly sleeved with the rotating ring 9. A connecting groove 17 is provided on one side of the rotating ring 9, and the transmission key 18 is slidingly connected with the connecting groove 17. A spring is provided between the rotating ring 9 and the connecting gear 11, and the spring corresponding to the rotating ring 9 is used to push the rotating ring 9 to maintain the sleeve with the moving sleeve 12. The movable block 19 is slidably connected to the grouting pipe 5, and the movable block 19 can slide axially without disengaging the grouting pipe 5. A spring for pushing the movable block 19 close to the sealing sleeve 6 is provided between the movable block 19 and the grouting pipe 5, and the connecting gear 11 and the outer gear 801 are meshed with each other.

[0031] In the process of the No. 2 movable seat 4 driving the grouting pipe 5 close to the wall, the sealing sleeve 6 is inserted into the grouting hole. At this time, the end of the adjusting rod 25 contacts the wall, and the No. 2 movable seat 4 continues to move, so that the guide rod 28 and the ratchet gear 802 move relative to the adjusting rod 25. The inner wall of the adjusting groove 26 corresponding to the adjusting rod 25 presses against the adjusting rod 25, driving the adjusting rod 25 to rotate relative to the No. 2 movable seat 4. The adjusting rod 25 rotates the one-way transmission to drive the outer gear 801 to rotate, and the movement of the grouting pipe 5 drives the connecting gear 11 to move synchronously. The rotation of the outer gear 801 drives the connecting gear 11 to rotate, and the connecting gear 11 drives the transmission ring 10 to rotate. The transmission ring 10 drives the rotating ring 9 to rotate through the transmission key 18, thereby rotating the movable sleeve 12, and driving the flexible pad 7 to shrink and arch during the process of the sealing sleeve 6 being inserted into the grouting hole.

[0032] When the sealing sleeve 6 is inserted, the adjusting rod 25 contacts and triggers the contact switch 29, and the contact switch 29 opens the corresponding solenoid valve, causing the contraction bag 21 to decompress and contract, and the transmission drives the sliding block 22 to contract, removing the limit on the No. 2 partition 15, to facilitate the subsequent withdrawal of the grouting pipe 5. When the No. 2 moving seat 4 drives the grouting pipe 5 to withdraw from the grouting hole, the spring corresponding to the sliding plug 31 drives the sliding plug 31 to slide and reset, and presses the air into the contraction bag 21 through the air outlet pipe 35, the connecting pipe 37 and the inner tube 14. When the sliding block 22 moves through the No. 2 partition 15, it drives the sliding block 22 to extend, thereby completing the telescopic control of the sliding block 22 and the end compression of the flexible pad 7 during the grouting process, further improving the efficiency of the grouting operation.

[0033] At the same time, the rotating ring 9 can move axially relative to the connecting gear 11, and the movable block 19 can move axially relative to the grouting pipe 5. When secondary grouting is required, the grouting pipe 5 is grouting based on the sealing sleeve 6 left during the first grouting of the sealing hole. When the movable sleeve 12 is loose, the movable sleeve 12 retreats a certain distance, and the grouting pipe 5 drives the rotating ring 9 to move. The rotating ring 9 rotates at the same time, so that the rotating ring 9 can resist the movable sleeve 12 and rotate, and the movable block 19 resists the sealing sleeve 6 and rotates, so that the rotating ring 9 is re-connected with the movable sleeve 12 of the retreated part, and the movable ring 16 is driven again to extrude the flexible pad 7 to ensure the sealing performance, improve the applicability of the drilling grouting device, and further improve the reliability of use.
