Description

Technical Field

[0001] This utility model relates to the technical field of water conservancy engineering construction equipment, specifically to a grouting device for water conservancy engineering channel construction. Background Technology

[0002] In the construction of water conservancy projects, grouting is a key technology. It involves injecting prepared grout into the gaps and cavities of the channel foundation or lining structure to improve the compaction of the foundation, enhance the stability and seepage prevention performance of the lining structure, thereby ensuring the normal operation and service life of the water conservancy project channel. The grouting device, as the core equipment for carrying out grouting operations, directly affects the grouting quality and construction efficiency.

[0003] In existing grouting devices for water conservancy projects, the grout tends to solidify on the inner wall of the grouting head during the grouting process. Once blocked, this not only requires a significant amount of time for disassembly and cleaning but also interrupts construction, reducing efficiency. Therefore, this paper proposes a grouting device for water conservancy project channel construction to address these problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, a grouting device for water conservancy engineering channel construction is provided. This technical solution solves the problem mentioned in the background art that the grout generated by the water conservancy engineering channel grouting device during the grouting process is prone to solidification on the inner wall of the grouting head, leading to blockage.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] The grouting head includes a first half connected to the end of the conveying pipe away from the pressure pump. A second half is rotatably connected to the end of the first half away from the conveying pipe. A groove is provided at the end of the first half opposite to the second half. A slider is fixedly connected to the end of the second half opposite to the first half. A first scraper is fixedly connected to the inner surface of the first half. A second scraper is fixedly connected to the inner surface of the second half. The first scraper and the second scraper are respectively attached to the inner surfaces of the second half and the first half.

[0008] Preferably, the slider is slidably connected to the inside of the groove.

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] Reference Figures 1-3 As shown, a grouting device for water conservancy engineering channel construction includes a mixing tank 1. A discharge port 10 is connected to the bottom of the outer surface of the mixing tank 1. A pressure pump 11 is connected to the front end of the discharge port 10. The pressure pump 11 acts as a switching device for grout delivery. Through the opening and closing of an electromagnetically controlled valve core, it achieves precise control of the grout flow within the delivery pipe 12. When open, the grout is allowed to pass through; when closed, the flow is blocked. The front end of the pressure pump 11 is connected to the delivery pipe 12, which delivers the grout output from the mixing tank 1 to the grouting head 13. The delivery pipe 12 is the channel for the grout from the mixing device to the grouting position and must possess certain corrosion resistance and pressure bearing capacity. The grouting head 13 is located at the end of the delivery pipe 12 furthest from the pressure pump 11.

[0023] The grouting head 13 includes a first half 1301 connected to the end of the conveying pipe 12 away from the pressure pump 11. A second half 1302 is rotatably connected to the end of the first half 1301 away from the conveying pipe 12. The first half 1301 and the second half 1302 together form the cavity of the grouting head 13, creating a channel for grout flow. They can rotate relative to each other, working with a scraper to clean the inner wall, forming a core structure for preventing clogging. A groove 1303 is provided at the opposite end of the first half 1301 and the second half 1302. A slider 1304 is fixedly connected to the opposite end of the second half 1302 and the first half 1301. The slider 1304 is slidably connected inside the groove 1303. The groove 1303 and the slider 1304 provide guidance and limitation for the relative rotation of the first half 1301 and the second half 1302, ensuring stable rotation and preventing detachment. A first scraper 1305 is fixedly connected to the inner surface of the first half 1301, and a second scraper 1306 is fixedly connected to the inner surface of the second half 1302. The first scraper 1305 and the second scraper 1306 are respectively attached to the inner surfaces of the second half 1302 and the first half 1301. As the two halves rotate relative to each other, the first scraper 1305 and the second scraper 1306 scrape off the residual grout on the inner wall of the other half to prevent solidification and blockage. When grouting is paused or completed, the second half 1302 is rotated, and the scraper rotates with the half to scrape off the grout adhering to the inner wall, ensuring that the inside of the grouting head 13 is smooth and unobstructed.

[0024] Furthermore, a support platform 2 is fixedly connected to the lower surface of the mixing tank 1, and a support column 3 is fixedly connected to each of the four corners of the lower surface of the support platform 2. A mounting plate 5 is fixedly connected to the outer surface of the support column 3, and a drive motor 6 is fixedly installed on the upper surface of the mounting plate 5. The output end of the drive motor 6 passes through the lower surface of the support platform 2 and is fixedly connected to a rotating shaft 7.

[0025] Furthermore, the other end of the rotating shaft 7 passes through the lower end of the mixing tank 1 and extends into the interior of the mixing tank 1. Several uniformly distributed stirring rods 8 are fixedly connected to the outer surface of the rotating shaft 7. The rotating shaft 7 transmits the power of the drive motor 6 to the stirring rods 8. The stirring rods 8 cut and mix the raw materials in the mixing tank 1 by rotating, so that the slurry composition is uniform and sedimentation and stratification are avoided.

[0026] Furthermore, the lower end of the support column 3 is rotatably connected to the movable wheel 4, which allows the operator to push the device to move within the construction site to meet the needs of different grouting locations.

[0027] Furthermore, a handrail 9 is fixedly connected to the upper surface of the support platform 2 at the rear side of the mixing tank 1. The handrail 9 is for the operator to hold, making it easy to push the device to move and control the direction during the movement, thereby improving the convenience and safety of operation.

[0028] Working Principle: When using this invention, first connect the external power supply to the device, then put the raw materials for preparing the slurry into the mixing tank 1. Check whether the first half 1301 and the second half 1302 of the grouting head 13 are tightly closed, and whether the first scraper 1305 and the second scraper 1306 are in contact with the inner wall. Push the handle 9, and move the device to the grouting position of the water conservancy project channel via the moving wheels 4. Lock the moving wheels 4 to prevent slippage, start the drive motor 6, and drive the rotating shaft 7 and the stirring rod 8 to rotate, stirring the raw materials in the tank. After stirring until the slurry reaches the specified uniformity, keep the motor running at low speed, turn on the pressure pump 11, and the slurry in the mixing tank 1 flows through the discharge port 10 and the conveying pipe 1... 2. The grouting head 13 is inserted into the grouting head 13 and injected into the target position of the channel. During the grouting process, the angle and depth of the grouting head 13 are adjusted as needed to ensure that the grout is filled in place. If grouting is paused, the pressure pump 11 is turned off and the second half 1302 is rotated so that the first scraper 1305 and the second scraper 1306 scrape off the inner wall of the other half to remove residual grout. Before grouting again, the pressure pump 11 is turned on and the new grout pushes the scraped-off residual part to the target position to ensure that the grouting head 13 is unobstructed. When the operation is finished, the drive motor 6 and the pressure pump 11 are turned off, the residual grout in the mixing tank 1, the conveying pipe 12 and the grouting head 13 are cleaned, and the device is pushed to the storage position to complete the operation.
