[0002] Road bridges generally consist of several major parts such as subgrade, pavement, bridge, tunnel engineering, and traffic engineering facilities. During the construction of roads and bridges, grouting is required for the road or bridge, and a grouting device is needed for grouting.

[0003] In the prior art, for example, Chinese Patent No.: CN218932875U discloses a grouting device for road and bridge construction, including a bottom plate. Universal wheels are movably connected to the four corners of the bottom of the bottom plate. A mortar bin is fixedly connected to the center of the top of the bottom plate. A slurry discharge funnel is fixedly connected to the bottom of the mortar bin. A slurry outlet is movably connected to the bottom of the slurry discharge funnel. An inlet is opened on one side of the top of the mortar bin. The advantages of the utility model are as follows: By passing the middle of the bottom plate, the slurry discharge funnel is arranged at the bottom of the bottom plate and communicated with the mortar bin. When it is necessary to inject mortar into the grouting port, the device is moved through the universal wheels to align the slurry discharge funnel with the grouting port for grouting. The bottom of the slurry discharge funnel is arranged at the front side of the bottom plate, making it more convenient to align the slurry outlet with the grouting port, avoiding the situation where the slurry outlet is located at the center of the bottom plate and the entire device needs to be moved above the grouting port, and also avoiding the situation where the bottom plate covers the grouting port and is inconvenient to observe.

[0004] However, when the above-mentioned patented grouting device is in use, due to the lack of measures to fix the entire device to the ground, it is easy for the vibration generated during the operation of the pumping pump to drive the entire device to shift in position, thereby affecting the working efficiency of grouting. Secondly, after the existing grouting device is used, a large amount of slurry will adhere to the inner wall of the slurry bucket, which is relatively inconvenient to clean and time-consuming and laborious.

[0005] Therefore, a grouting device for road and bridge construction is proposed to solve the above problems. Summary of the Utility Model

The four support rods 3 support and install the fixed seat 301, so that the first barrel 4 can be fixedly embedded and installed on the surface of the fixed seat 301. By controlling the stirring device 5, the slurry inside the first barrel 4 can be stirred and mixed. When it is necessary to clean the inside of the first barrel 4, water can be added to the inside of the first barrel 4, and by controlling the stirring device 5, the inner wall of the first barrel 4 can be scraped to clean the slurry inside the first barrel 4. Installing the two connecting plates 6 facilitates the setting of the fixing device 7 and is convenient for stabilizing the whole device during grouting.

[0026] In one embodiment, an installation groove 101 is formed on the surface of the base 1. A storage battery 102 is installed on one side of the surface of the base 1, a handrail 103 is installed on the other side of the surface of the base 1, a control terminal 104 is installed on one side of the handrail 103, and a device housing 105 is installed on one side of the bottom of the base 1.

[0027] Specifically: The inside of the installation groove 101 is convenient for installing the first barrel 4 and the second barrel 403. The base 1 can be pushed to the position where grouting is required through the handrail 103. The storage battery 102 provides power for each power-receiving controlled device, and the control terminal 104 is electrically connected to each power-receiving controlled device.

[0029] Specifically: Pour the slurry into the inside of the feed inlet 401, so that the slurry enters the inside of the first barrel 4 and is stirred and mixed by the stirring device 5. After the grouting is completed, add water into the inside of the first barrel 4 through the water inlet 402 for cleaning. Sealing plugs are plugged inside both the feed inlet 401 and the water inlet 402, which can be plugged when not in use. When grouting the ground, by starting the slurry pump 405, the operation of the slurry pump 405 can pump out the slurry in the second barrel 403 through the feed pipe 404, so that the pumped slurry enters the nozzle 407 through the discharge pipe 406, and finally is sprayed through the nozzle 407 for grouting.

[0030] In one embodiment, the stirring device 5 includes a motor 501. The motor 501 is fixedly installed on the top of the first barrel 4. The output end of the motor 501 is fixedly installed with a rotating rod 502. A plurality of stirring rods 503 are installed on the surface of the rotating rod 502. U-shaped scraping plates 504 are installed on both sides of the surface of the rotating rod 502. A plurality of stirring blades 505 are installed on one side of each of the two U-shaped scraping plates 504. Two scraping plates 506 are installed at the bottom of the surface of the rotating rod 502. One end of each of the two scraping plates 506 is connected to one side of the bottom of the two U-shaped scraping plates 504. Both of the two scraping plates 506 are movable inside the second barrel 403.

[0031] Specifically: The motor 501 can be started through the control terminal 104. The operation of the motor 501 can drive multiple stirring rods 503 on the surface of the rotating rod 502 to stir and mix the slurry inside the first barrel 4, which can prevent the slurry from solidifying after being placed for a long time. The two U-shaped scraping plates 504 can be attached to the inner wall of the first barrel 4, so that when the motor 501 drives the rotating rod 502 to rotate, the U-shaped scraping plates 504 can rotate and scrape the material, which is convenient for cleaning the inner wall of the first barrel 4. And multiple stirring blades 505 on one side of the two U-shaped scraping plates 504 can rotate and stir the slurry accordingly, which can increase the stirring efficiency of the slurry. The two scraping plates 506 can be attached to the inner wall of the second barrel 403 and scrape and clean the slurry adhering to the inner wall.

[0032] In one embodiment, the fixing device 7 includes two electric push rods 701. The two electric push rods 701 are both fixedly embedded on the surface of the connecting plate 6. One end of each of the two electric push rods 701 is provided with a pressing plate 702, and four insertion rods 703 are installed at the four ends of the bottom of the pressing plate 702.

[0033] Specifically: During the process of grouting the ground, the whole device will vibrate. Since some grouting roads have a certain slope, it is easy for the whole device to move. At this time, the two electric push rods 701 can be started. The two electric push rods 701 can drive the pressing plate 702 connected to one end to move downward, so that the four insertion rods 703 at the bottom of the pressing plate 702 are inserted into the ground. The bottom ends of the four insertion rods 703 are conical, which is convenient for embedding into the ground. Since the pressing plate 702 has a certain weight, the pressing plate 702 can be embedded into the ground by the downward pushing force of the two electric push rods 701, so that the whole device operates stably.

[0034] In one embodiment, the feeding port 401, the water inlet 402, the second barrel 403 and the inside of the first barrel 4 communicate with each other. The second barrel 403 is located inside the installation groove 101.

[0035] Specifically: The slurry can be added into the inside of the first barrel 4 through the feeding port 401, and water can be added into the inside of the first barrel 4 through the water inlet 402. The inside of the first barrel 4 and the second barrel 403 communicate with each other, so that both the slurry and water can be transported outward through the conveying pipe 404. The second barrel 403 connected to the bottom of the first barrel 4 is located inside the installation groove 101, which is convenient for both the conveying pipe 404 and the bottom end of the second barrel 403 to be connected.

[0036] Working principle: The pulp extraction pump 405, the motor 501, the electric push rod 701 and the control terminal 104 are electrically connected. When in use, the entire device can be pushed to the place where grouting is required through the handrail 103. By starting the four electric push rods 701 through the control terminal 104, the operation of the electric push rods 701 can drive the two pressing plates 702 to move downward. Since the pressing plates 702 have a certain weight, the two pressing plates 702 can be pressed downward and embedded in the ground, and the four inserting rods 703 at the bottom of the pressing plates 702 are inserted into the ground accordingly. At this time, the entire device can be stably placed through the two pressing plates 702. By starting the pulp extraction pump 405 through the control terminal 104, the operation of the pulp extraction pump 405 can extract the pulp inside the second barrel 403 through the feeding pipe 404. The extracted pulp is transported to the discharge pipe 406 through the feeding pipe 404, and finally the pulp is sprayed out through the nozzle 407 to grout the ground. By setting the two fixing devices 7, the stability of the entire device can be increased during the process of grouting the ground, and the position deviation of the entire device during the grouting process can be avoided, which affects the working efficiency of grouting. The motor 501 can be started through the control terminal 104. The operation of the motor 501 can drive the multiple stirring rods 503 on the surface of the rotating rod 502 to stir and mix the pulp inside the first barrel 4, and multiple stirring blades 505 follow to stir, so that the pulp is stirred evenly. The two scraping plates 506 can stir the pulp inside the second barrel 403. When it is necessary to clean the inside of the first barrel 4 after the grouting is completed, water is added into the first barrel 4 through the water inlet 402. By driving the two U-shaped scraping plates 504 to rotate through the control of the motor 501, the inner wall of the first barrel 4 can be rotated and scraped, so that the two U-shaped scraping plates 504 can clean the pulp adhered to the inner wall of the first barrel 4, and the two scraping plates 506 clean the inner wall of the second barrel 403. Starting the pulp extraction pump 405 can make the pulp water after cleaning inside the first barrel 4 be discharged outward through the nozzle 407. By setting the stirring device 5, the pulp inside the first barrel 4 can be stirred and mixed, and after the grouting is completed, the pulp adhered to the inner walls of the first barrel 4 and the second barrel 403 can be cleaned, which is more convenient.
