Description
Technical Field
[0001] The utility model relates to the technical field of rock and soil grouting, and more specifically to a rock and soil grouting device. Background Art
[0002] Geotechnical grouting device is a device used in civil engineering to inject slurry into rock or soil layers through high or low pressure to improve the bearing capacity of the foundation, waterproofness or reinforce the structure. The traditional geotechnical grouting device uses an air pump to inject the stirred slurry into the required gap or rock and soil through a grouting sealer, and then forms the corresponding reinforcement. The grouting sealer can effectively seal the holes opened in the rock and soil, and at the same time reduce the cracks in the rock or coal seam around the borehole and enhance the stability of the structure. The slurry is usually composed of cement slurry, polymer materials and additives, which are injected through the grouting pipe in the grouting sealer.
[0003] Grouting is carried out into the holes opened in the rock and soil through the grouting sealer. When the grouting is completed, because the slurry contains a large amount of cement particles and the slurry has a certain viscosity, a large amount of slurry and cement particles will remain on the inner wall of the grouting pipe. If they are not removed in time, the slurry and cement particles will solidify, thereby clogging the inner wall of the grouting pipe, affecting the next use, and the grouting pipe will be scrapped after a long time. Utility Model Content

DETAILED DESCRIPTION
[0021] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.
[0022] Figure 1 to Figure 6 It is the best embodiment of the utility model, and the following Figure 1 to Figure 6 The utility model is further described.
[0023] The utility model discloses a rock and soil grouting device, including a grouting pipe 1, a screw rod 2 is fixedly installed at one end of the grouting pipe 1, the screw rod 2 is hollow and connected to the grouting pipe 1, and a cleaning component 3 for cleaning the inside of the grouting pipe 1 and the screw rod 2 is arranged at the other end. A connecting component 4 is arranged on the grouting pipe 1, and a plurality of bags 5 are arranged on the connecting component 4. An extrusion component 6 for expanding the plurality of bags 5 is arranged in the connecting component 4. A limiting component 7 rotating along the screw rod 2 is arranged on the screw rod 2, and the limiting component 7 can make the extrusion component 6 move along the connecting component 4 and limit the extrusion component 6. A feeding pipe 8 is fixedly connected at the other end of the screw rod 2.
[0024] In this embodiment, the bladder bag 5 is made of rubber material and has a certain elasticity. When in use, when the stirred slurry needs to be injected into the rock and soil, the staff will open a hole in the rock and soil in advance, and then the staff will insert the end of the grouting pipe 1 with the bladder bag 5 into the hole. At this time, the staff rotates the limit assembly 7, and the limit assembly 7 rotates along the screw 2 and moves toward the extrusion assembly 6. The limit assembly 7 squeezes the extrusion assembly 6, so that the extrusion assembly 6 moves along the connecting assembly 4, so that the gas in the connecting assembly 4 moves toward the plurality of bladder bags 5. The plurality of bladder bags 5 expand, and the expanded bladder bags 5 contact the inner wall of the hole, so that the friction between the bladder bag 5 and the inner wall of the hole increases, so that the grouting pipe 1 is fixed to the hole, which is convenient for subsequent grouting into the hole. The limit assembly 7 is limited by the thread on the screw 2. At this time, the grouting pipe 1 is fixed in the hole, and the feed pipe 8 is connected to the feeding pipe, and the slurry is transported to the feed pipe 8, so that the slurry enters the screw rod 2 through the feed pipe 8, and enters the grouting pipe 1 from the screw rod 2, and exits from the cleaning component to grout into the rock and soil that needs grouting. When the grouting is completed, the staff reversely rotates the limit assembly 7 to keep the limit assembly 7 away from the extrusion assembly 6 and does not squeeze the extrusion assembly 6. The extrusion assembly 6 returns to the initial state, and the gas in the connecting assembly 4 no longer expands the plurality of bladders 5, and the bladders 5 no longer contact the inner wall of the hole. The staff can take out the grouting pipe 1. The feed pipe 8 will no longer be connected to the feeding pipe. The grouting pipe 1 is in an inclined state, and the slurry remaining in the grouting pipe 1 and the screw rod 2 is cleaned by the cleaning assembly 3.
[0025] Specifically, the connecting assembly 4 includes a connecting pipe 401, an annular groove 402 and a plurality of connecting holes 403. The connecting pipe 401 is fixedly sleeved on the grouting pipe 1. The inner wall of the connecting pipe 401 is fixedly connected to the surface of the grouting pipe 1. The annular groove 402 is provided on the inner wall of the connecting pipe 401. A plurality of connecting holes 403 are provided on the surface of the connecting pipe 401 and are away from one end of the screw rod 2. A plurality of connecting holes 403 are connected to the annular groove 402. A plurality of bladder bags 5 are respectively fixedly sleeved on the connecting pipe 401, and a plurality of bladder bags 5 correspond to a plurality of connecting holes 403 one by one. The extrusion assembly 6 includes a fixed plate 601, a plurality of springs 602, a movable plate 603 and an annular pipe 604. The annular pipe 604 is sleeved on the grouting pipe 1 and is located in the annular groove 402. The annular pipe 604 is slidably matched with the inner wall of the annular groove 402 and the grouting pipe 1, and the annular groove 402 can be sealed by a plurality of bladder bags 5 and the annular pipe 604. One end of the annular tube 604 extends to the outside of the annular groove 402 and is fixedly connected to the movable plate 603. The fixed plate 601 is fixedly sleeved on the connecting tube 401. A plurality of springs 602 are arranged on the fixed plate 601 in a circular shape and are equidistant. One end of the plurality of springs 602 is connected to the fixed plate 601, and the other end is fixedly connected to the movable plate 603. The limit assembly 7 includes a slider 701 and two connecting rods 702. The slider 701 is sleeved on the screw rod 2 and is threadedly connected to the screw rod 2. One end of the two connecting rods 702 is fixedly connected to the surface of the slider 701, and the two connecting rods 702 are symmetrically arranged.
[0026] In this embodiment, when the grouting pipe 1 needs to be fixed in the hole on the rock, the staff rotates the connecting rod 702, and the connecting rod 702 drives the slider 701 to rotate, and the slider 701 rotates along the screw 2, so that the slider 701 moves downward. The slider 701 moves downward to contact the movable plate 603 and squeezes the movable plate 603. The movable plate 603 drives the annular tube 604 to move and squeezes a plurality of springs 602. The annular tube 604 moves along the annular groove 402 and pushes the gas in the annular groove 402, so that the gas in the annular groove 402 moves toward the connecting hole 403. The gas passes through the connecting hole 403, and the gas pushes a plurality of bladder bags 5, so that the plurality of bladder bags 5 expand. The expanded plurality of bladder bags 5 contact the inner wall of the hole, so that the friction between the bladder bags 5 and the inner wall of the hole increases, so that the grouting pipe 1 is fixed to the hole, which is convenient for subsequent grouting into the hole. Because the thread on the screw 2 restricts the slider 701, the slider 701 does not move. When the grouting is completed, the staff rotates the connecting rod 702 in the opposite direction. The connecting rod 702 drives the slider 701 to rotate in the opposite direction, so that the slider 701 rotates along the screw rod 2 and moves upward. At this time, the spring 602 drives the moving plate 603 to rebound, and the moving plate 603 drives the annular tube 604 to move upward. The gas in the annular groove 402 no longer expands the bladder 5, and the bladder 5 no longer contacts the inner wall of the hole. When the moving plate 603 is no longer in contact with the slider 701, the moving plate 603 returns to the initial state and waits for the next work.
[0027] Specifically, the cleaning assembly 3 includes a discharge pipe 301 and a scraper 302. One end of the discharge pipe 301 is rotatably connected to the other end of the grouting pipe 1 and communicates with the grouting pipe 1. The scraper 302 is fixedly mounted on the inner wall of the discharge pipe 301, one end of the scraper 302 passes through the grouting pipe 1 and extends into the screw 2, and the scraper 302 is in contact with the inner walls of the grouting pipe 1 and the screw 2.
[0028] In this embodiment, when injecting slurry into the hole, the slurry flows from the grouting pipe 1 to the discharge pipe 301, and is injected into the hole through the discharge pipe 301. When the injection pipe is taken out from the hole, slurry remains on the inner walls of the grouting pipe 1 and the screw rod 2, and cement particles in the slurry are adsorbed on the inner walls of the grouting pipe 1 and the screw rod 2. At this time, the staff makes the grouting pipe 1 in an inclined state and rotates the discharge pipe 301, and the discharge pipe 301 drives the scraper 302 to rotate, and the scraper 302 scrapes the slurry and cement particles remaining on the inner walls of the grouting pipe 1 and the screw rod 2. The scraped slurry and cement particles flow out of the discharge pipe 301 along the inclined grouting pipe 1 and the screw rod 2, preventing the slurry and cement particles from remaining on the inner walls of the grouting pipe 1 and the screw rod 2.
[0029] Specifically, a rubber ring 9 is fixedly mounted on one end of the annular tube 604 located in the annular groove 402 .
[0030] In this embodiment, the rubber ring 9 moves synchronously with the annular tube 604 , and the rubber ring 9 increases the air tightness to prevent the gas from flowing out of the annular groove 402 .
