Description

Technical Field

[0001] The invention relates to the technical field of material grouting, and in particular to a grouting device and method for reinforcing materials. Background Art

[0002] A grouting machine is a device used in civil engineering and building construction. During the construction process, when a cavity appears after the concrete solidifies due to volume shrinkage of the slurry, insufficient compaction, or air bulging, it is necessary to drill grouting holes and detection holes in the soil that are connected to the cavity, insert supporting components such as grouting nails into the grouting holes, and then use a grouting machine to inject slurry such as cement slurry into the cavity along the grouting nails as a reinforcement material, thereby reinforcing and supporting the concrete under the ground. When the slurry is injected into the grouting hole, the slurry will squeeze the gas in the grouting hole and the cavity and output it to the atmosphere through the detection hole. When the cavity is filled with the slurry, the slurry will be ejected through the detection hole, so as to detect the content of the slurry in the cavity.

[0003] For example, according to the Chinese patent with the authorization announcement number CN118065373B and the name of the patent being an electric grouting device, the device is manually moved to the grouting position, slurry is injected into pipe two, the slurry flows into funnel two, and then flows into cylinder one through funnel two, the motor one is started, the motor one drives the round rod to rotate, the round rod drives blade one to rotate, the blade one stirs the defoaming agent and the slurry, the hose is manually removed from cylinder two, and then the nozzle two is aimed at the cavity of the underground concrete engineering building, the pump body is started, the slurry flows into the hose through pipe seven, and then is poured into the cavity from nozzle two.

[0004] With regard to the above-mentioned related technologies, when the cavity is filled with slurry, the grouting machine continues to transport slurry into the cavity, which will increase the internal pressure of the pipeline and increase the probability of the grouting machine pipeline being broken and damaged. In addition, when construction workers observe the slurry sprayed out of the detection hole, the slurry disperses around and has a chance of splashing onto construction workers, thus creating a safety hazard in construction. Summary of the invention

DETAILED DESCRIPTION

[0037] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 7 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0038] In the first aspect, this embodiment provides a grouting device for reinforcing material, referring to Figure 1 and Figure 2 A grouting device for reinforcing materials includes a support plate 1, a storage barrel 2, a grouting pipe 21, a grouting pump 22, a first grouting nail 3, a detection mechanism for detecting the amount of slurry poured into a concrete cavity, and a regulating mechanism for reducing the internal pressure of the grouting pipe 21.

[0039] Reference Figure 1 and Figure 2 The support plate 1 is fixedly connected with a handle 11, and the lower surface of the support plate 1 is rotatably connected with a roller 12. The construction personnel drive the support plate 1 to move through the handle 11 and the roller 12. The storage barrel 2 is fixedly connected to the upper surface of the support plate 1, and the storage barrel 2 is filled with slurry. The slurry pipe 21 is fixedly connected to the side wall of the storage barrel 2. The slurry pump 22 is fixedly connected to the upper surface of the support plate 1, and the slurry pump 22 is connected to the slurry pipe 21. The slurry pump 22 is used to extract the slurry in the storage barrel 2 to the slurry pipe 21. The first grouting nail 3 is detachably connected to the end of the slurry pipe 21 away from the storage barrel 2. The first grouting nail 3 is connected to the grouting pipe 21. The first grouting nail 3 is arranged in the grouting hole and is used to inject slurry into the grouting hole.

[0040] Reference Figure 1 and Figure 2 The regulating mechanism includes: a slurry outlet pipe 23, a closing member 24 and a detection pipe 25. The slurry outlet pipe 23 is fixedly connected to the side wall of the slurry delivery pipe 21, and the closing member 24 is slidably connected to the inside of the slurry outlet pipe 23 to control the communication state inside the slurry outlet pipe 23. The detection pipe 25 is slidably sleeved on the outer side wall of the closing member 24, and the detection pipe 25 is fixedly connected to the support plate 1, and the detection pipe 25 is filled with hydraulic oil.

[0041] Reference Figure 2 and Figure 3 The detection mechanism includes: a second grouting nail 4, a material feeding shell 41, a transmission block 42, a waterproof breathable membrane 43, a first return spring 44 and an air outlet 45. The second grouting nail 4 is arranged at the end of the detection tube 25 away from the closure 24, and the second grouting nail 4 is arranged in the detection hole. The material feeding shell 41 is arranged between the second grouting nail 4 and the detection tube 25, and the second grouting nail 4 and the detection tube 25 are respectively connected to the material feeding shell 41, and the second grouting nail 4 is detachably connected to the material feeding shell 41.

[0042] Reference Figure 2 and Figure 3 The transmission block 42 is slidably connected in the feeding housing 41, and the transmission block 42 is used to squeeze the hydraulic oil to flow. The waterproof breathable membrane 43 and the first return spring 44 are both fixedly connected to the transmission block 42. The waterproof breathable membrane 43 allows gas to pass through, and the waterproof breathable membrane 43 restricts the passage of liquid. The end of the first return spring 44 away from the transmission block 42 is fixedly connected to the detection tube 25. The air outlet 45 is opened on the side wall of the feeding housing 41, and the waterproof breathable membrane 43 is arranged below the transmission block 42.

[0043] When it is necessary to inject slurry and other reinforcement materials into the cavity in the ground, the construction personnel drill grouting holes and detection holes in the ground, both of which are connected to the cavity, and place the first grouting nail 3 in the grouting hole and the second grouting nail 4 in the detection hole. The slurry delivery pump 22 is started to inject the slurry in the storage barrel 2 into the first grouting nail 3 through the slurry delivery pipe 21, and the slurry in the first grouting nail 3 enters the cavity through the grouting hole, and the gas in the cavity enters the delivery housing 41 through the detection hole and the second grouting nail 4, and the gas in the delivery housing 41 passes through the waterproof breathable membrane 43 and is then output through the air outlet 45.

[0044] When the cavity in the ground is filled, the slurry in the cavity is injected into the second grouting nail 4 through the detection hole, and the slurry in the second grouting nail 4 enters the feed shell 41. The slurry squeezes the transmission block 42 and the waterproof breathable membrane 43 to move away from the second grouting nail 4. The inner side wall of the feed shell 41 is fixedly connected to a limit ring 46, which is used to limit the waterproof breathable membrane 43 from moving upward to above the air outlet 45. The limit ring 46 limits the slurry from being output through the air outlet 45.

[0045] The transmission block 42 squeezes the hydraulic oil and moves along the detection tube 25 close to the slurry outlet pipe 23. The hydraulic oil pushes the closing piece 24 to move out of the slurry outlet pipe 23. At this time, the slurry delivery pipe 21 is connected to the atmosphere through the slurry outlet pipe 23, and the pressure of the slurry in the ground cavity is greater than the atmospheric pressure. The slurry in the slurry delivery pipe 21 stops injecting slurry into the first grouting nail 3, so that the slurry is directly output through the slurry outlet pipe 23. At this time, the first return spring 44 is compressed.

[0046] After the slurry is output through the slurry outlet pipe 23, the construction personnel remove the slurry delivery pipe 21 from the first grouting nail 3, and remove the material delivery shell 41 from the second grouting nail 4. The material delivery shell 41 is connected to the outside atmosphere, thereby the pressure in the material delivery shell 41 is reduced, and the compressed first return spring 44 pushes the transmission block 42 to move away from the slurry outlet pipe 23 for reset. The transmission block 42 drives the closing piece 24 to move into the slurry outlet pipe 23 through the hydraulic oil, so that the closing piece 24 blocks the slurry outlet pipe 23.

[0047] The slurry filled in the cavity in the ground is used as a driving source to push the closing member 24 to open the slurry outlet pipe 23, so that after the cavity in the ground is filled with slurry, the closing member 24 can automatically open the slurry outlet pipe 23, stop injecting slurry into the cavity, reduce the pressure in the slurry delivery pipe 21, and reduce the probability of the slurry delivery pipe 21 being broken and damaged after the cavity is filled with slurry. At the same time, the slurry output through the slurry outlet pipe 23 can serve as a signal that the cavity in the ground is filled, and the slurry outlet pipe 23 outputs slurry in a specific direction, reducing the probability of slurry splashing to construction personnel and reducing construction hazards.

[0048] Reference Figure 4 The inner side wall of the slurry delivery pipe 21 is fixedly connected with a material blocking ring 231, and the side wall of the material blocking ring 231 is tapered. A closing rod 26 that can abut against the material blocking ring 231 is slidably connected in the slurry delivery pipe 21. The closing rod 26 is arranged between the slurry outlet pipe 23 and the first grouting nail 3. One end of the closing rod 26 is tapered, and the tapered surface of the closing rod 26 is parallel to the side wall of the material blocking ring 231. An extrusion spring 27 is arranged in the slurry delivery pipe 21 for driving the closing rod 26 to move to the material blocking ring 231.

[0049] When the slurry delivery pipe 21 delivers slurry to the first grouting nail 3, the slurry flows and squeezes the closing rod 26 to separate from the blocking ring 231, and the slurry flows to the first grouting nail 3 through the gap between the closing rod 26 and the blocking ring 231, and the squeezing spring 27 is compressed at this time. When the closing member 24 moves out of the slurry outlet pipe 23, so that the slurry outlet pipe 23 is opened, the slurry is discharged through the slurry outlet pipe 23, thereby reducing the flow rate of the slurry in the slurry delivery pipe 21, thereby reducing the squeezing force of the slurry on the closing rod 26, and the squeezing spring 27 pushes the closing rod 26 to abut against the blocking ring 231 to close the slurry delivery pipe 21, thereby improving the reliability of the slurry in the storage barrel 2 being discharged through the slurry outlet pipe 23 after the cavity in the ground is filled with slurry.

[0050] Reference Figure 4 and Figure 5 A filter plate 5 is hinged in the slurry delivery pipe 21, and the filter plate 5 is located at the junction of the slurry delivery pipe 21 and the slurry outlet pipe 23. A return torsion spring 51 is fixedly connected between the slurry delivery pipe 21 and the filter plate 5. The filter plate 5 is fixedly connected to a first connecting rod 52. The first connecting rod 52 is hinged to a second connecting rod 53 at one end away from the filter plate 5. The second connecting rod 53 is hinged to the closing rod 26 at one end away from the first connecting rod 52.

[0051] When the closing rod 26 contacts the blocking ring 231, the reset torsion spring 51 makes the filter plate 5 and the slurry delivery pipe 21 have an axial tilt angle. Specifically, the angle between the filter plate 5 and the slurry delivery pipe 21 is 45 degrees. When the slurry flows from the slurry delivery pipe 21 to the slurry outlet pipe 23, the impurities on the side wall of the filter plate 5 are washed away. When the slurry delivery pipe 21 delivers slurry to the first grouting nail 3, the slurry pushes the closing rod 26 to break away from the blocking ring 231. The closing rod 26 moves through the first connecting rod 52 and the second connecting rod 53 to drive the filter plate 5 to rotate counterclockwise (refer to Figure 5 ), so that the filter plate 5 is perpendicular to the axial direction of the slurry delivery pipe 21, so that the slurry needs to be filtered through the filter plate 5 when flowing to the first grouting nail 3, thereby reducing the probability of impurities in the slurry clogging the first grouting nail 3 and the grouting hole.

[0052] The slurry flows through the slurry delivery pipe 21 and the slurry outlet pipe 23 to control the inclination angle of the filter plate 5 and the slurry delivery pipe 21, so that when the slurry flows to the first grouting nail 3, the filter plate 5 can filter the slurry, and when the slurry is output through the slurry outlet pipe 23, the slurry can flush the side wall of the filter plate 5.

[0053] Reference Figure 1 , Figure 6 and Figure 7 The support plate 1 is fixedly connected to a liquid storage barrel 6 with cleaning liquid arranged inside, a first liquid inlet pipe 61 is fixedly connected between the material storage barrel 2 and the liquid storage barrel 6, a material blocking plate 62 for closing the first liquid inlet pipe 61 is slidably connected inside the liquid storage barrel 6, and the material blocking plate 62 is provided with a transmission mechanism, and when the closing piece 24 moves out of the slurry outlet pipe 23, the transmission mechanism is used to drive the material blocking plate 62 to separate from the first liquid inlet pipe 61.

[0054] Reference Figure 6 and Figure 7 The transmission mechanism includes: a first transmission rod 63, a second transmission rod 64 and a second return spring 65. The first transmission rod 63 is fixedly connected to the material blocking plate 62, and the first transmission rod 63 is provided with a first transmission inclined surface 631, and the first transmission inclined surface 631 is fixedly connected to the first slider 632. The second transmission rod 64 is provided with a second transmission inclined surface 641, and the second transmission inclined surface 641 is provided with a first slide groove 642 that can be adapted to the first slider 632. The closing member 24 and the second return spring 65 are arranged at both ends of the second transmission rod 64 and are both fixedly connected to the second transmission rod 64, and the second return spring 65 is fixedly connected to the support plate 1 at one end away from the second transmission rod 64.

[0055] When the closing member 24 moves into the slurry outlet pipe 23 and closes the slurry outlet pipe 23, the material blocking plate 62 abuts against the first liquid inlet pipe 61, so that the material blocking plate 62 restricts the cleaning liquid in the liquid storage barrel 6 from entering the material storage barrel 2. When the hydraulic oil pushes the closing member 24 to move out of the slurry outlet pipe 23, the closing member 24 drives the second transmission rod 64 to move, and the second transmission rod 64 drives the first transmission rod 63 to move downward through the inclined first slide groove 642 and the first slider 632, and the material blocking plate 62 moves synchronously with the first transmission rod 63, so that the material blocking plate 62 is separated from the first liquid inlet pipe 61, so that the cleaning liquid in the liquid storage barrel 6 enters the material storage barrel 2 through the first liquid inlet pipe 61, and the slurry delivery pump 22 is started to make the cleaning liquid flow to the slurry outlet pipe 23 through the slurry delivery pipe 21, and the cleaning liquid flushes the material storage barrel 2, the slurry delivery pipe 21 and the slurry outlet pipe 23, and the cleaning liquid further cleans the filter plate 5. At this time, the second return spring 65 is compressed.

[0056] When all the cleaning liquid flows out of the slurry discharge pipe 23, the construction personnel disassemble the slurry delivery pipe 21 and the material delivery housing 41, and the hydraulic oil stops squeezing the closing member 24. The compressed second return spring 65 drives the second transmission rod 64 to move closer to the slurry discharge pipe 23 and reset, and the second transmission rod 64 drives the first transmission rod 63 to move upward through the first slide groove 642 and the first slider 632, and the material blocking plate 62 moves synchronously with the first transmission rod 63 to close the first liquid inlet pipe 61.

[0057] Reference Figure 1 and Figure 6 The upper surface of the support plate 1 is fixedly connected with a feed barrel 7 and a liquid feed barrel 8. The feed barrel 7 is used to receive cement raw materials, and the liquid feed barrel 8 is used to receive water. A feed pipe 71 is fixedly connected between the feed barrel 7 and the storage barrel 2, and a second liquid feed pipe 81 is fixedly connected between the liquid feed barrel 8 and the storage barrel 2. A control valve 711 is connected in series inside the feed pipe 71 and the second liquid feed pipe 81. The feed pipe 71 and the second liquid feed pipe 81 are both in contact with the material blocking plate 62. A rotating source 9 is fixedly connected to the upper surface of the storage barrel 2. The driving shaft of the rotating source 9 is fixedly connected with a stirring paddle 91. The stirring paddle 91 is located in the storage barrel 2. The material blocking plate 62 is provided with a feeding hole 621. The feed pipe 71 and the second liquid feed pipe 81 can both be connected to the feeding hole 621.

[0058] When the closing member 24 moves into the slurry outlet pipe 23 and closes the slurry outlet pipe 23, the feed pipe 71 and the second liquid inlet pipe 81 are both connected to the feed hole 621, and the control valve 711 is opened to allow the cement raw material to enter the storage barrel 2 through the feed pipe 71, and the water to enter the storage barrel 2 through the second liquid inlet pipe 81. The rotation source 9 drives the stirring paddle 91 to rotate and stir the cement raw material and water into slurry. When the first transmission rod 63 drives the material blocking plate 62 to disengage from the first liquid inlet pipe 61, the feed hole 621 and the material blocking plate 62 move synchronously to disengage from the feed pipe 71 and the second liquid inlet pipe 81, and the material blocking plate 62 blocks the feed pipe 71 and the second liquid inlet pipe 81. When the ground cavity is filled with slurry, the material blocking plate 62 can automatically limit the feed barrel 7 and the liquid inlet barrel 8 from continuing to transport raw materials to the storage barrel 2.

[0059] The implementation principle of a grouting device for reinforcing materials in an embodiment of the present invention is as follows: construction personnel drill grouting holes and detection holes on the ground, place the first grouting nail 3 in the grouting hole, and place the second grouting nail 4 in the detection hole. The grouting pump 22 is started to allow the slurry to enter the cavity through the first grouting nail 3.
