[0002] During the construction of municipal roads and bridges, compaction grouting is mainly used to reinforce the foundation. The compaction grouting process involves injecting grout into the soil under pressure through a grouting pipe, forming grout bubbles and a grout-soil bond around the grouting pipe, which compresses and compacts the soil, thus comprehensively reinforcing the foundation soil.

[0003] Existing compaction grouting devices use grout pumps to extract grout from the cylinder, but some grout tends to clump at the cylinder's outlet and cause blockages, affecting road construction operations.

[0004] Therefore, it is particularly important to design a municipal road and bridge construction compaction grouting equipment that can prevent blockage inside the discharge pipe to overcome the above-mentioned technical defects and improve overall practicality. Utility Model Content

On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0022] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0023] A municipal road and bridge construction compaction grouting device that can prevent blockage inside the discharge pipe includes a movable push plate 1. Walking wheels 2 are symmetrically installed on the right side of the bottom of the movable push plate 1. A pressure roller 3 is rotatably installed on the left side of the bottom of the movable push plate 1. A grouting cylinder 4 is installed on the top of the movable push plate 1. An inlet pipe 401 is installed on the top of the grouting cylinder 4. A discharge pipe 402 extends from the bottom of the grouting cylinder 4 below the movable push plate 1. A cleaning water tank 5 is installed on the right side of the grouting cylinder 4. A cleaning water pipe 501 is connected to the right side of the cleaning water tank 5. A spray head 502 is connected to the end of the cleaning water pipe 501 away from the cleaning water tank 5. A control water valve 503 is installed in the middle section of the cleaning water pipe 501. An anti-blocking cleaning mechanism 6 is provided at the bottom of the movable push plate 1 to cooperate with the discharge pipe 402.

[0024] Mud pumps are installed in the middle sections of both the feed pipe 401 and the discharge pipe 402. The mud pumps are connected to the control panel by wires, and the connection is electrical.

[0025] In this embodiment, the anti-clogging cleaning mechanism 6 includes an electric push rod 601 installed at the bottom of the movable push plate 1 with its output end facing downward. A folding bracket 602 is fixed to the output end of the electric push rod 601. A rotary motor 603 is installed on the inner side of the folding bracket 602. A drive gear 604 is connected to the output end of the rotary motor 603. A short shaft 605 is rotatably connected to the bottom of the folding bracket 602. The top end of the short shaft 605 passes through the folding bracket 602 and is fixed with a driven gear 606 that meshes with the drive gear 604. A movable base plate 607 is installed at the bottom of the short shaft 605. A drive motor 608 is installed at the center of the bottom of the movable base plate 607. The output end of the drive motor 608 passes through the top of the movable base plate 607 and is connected to a cleaning brush roller 609 that works with the discharge pipe 402.

[0026] The grouting cylinder 4 has a control panel on its outer side. The control panel is connected to the control water valve 503, electric push rod 601, rotary motor 603 and drive motor 608 by wires, and the connection is electrical. The top of the cleaning water tank 5 is provided with an injection port. The spray head 502 is designed to correspond to the position of the cleaning brush roller 609. The electric push rod 601 is fixedly installed at the bottom of the movable push plate 1 by bolts and is located at the right end of the discharge pipe 402. The external structure size of the cleaning brush roller 609 is adapted to the internal structure size of the discharge pipe 402.

[0027] The working process of this utility model is as follows: When the municipal road and bridge construction compaction grouting equipment and structure designed in this scheme to prevent blockage inside the discharge pipe is in operation, the mud pump can extract the grout from the grouting cylinder 4, causing the grout inside the grouting cylinder to spray out from the discharge pipe 402. During the intermittent period when the grout output stops, the electric push rod 601 in the anti-blockage cleaning mechanism can be activated, causing the electric push rod 601 to drive the folding bracket 602 to move downwards. Then, the rotary motor 603 drives the drive gear 604 and the driven gear 606 to mesh, causing the short shaft 605 to start rotating. This moves the movable base plate 607, which was originally rotating on the outside, to the bottom of the discharge pipe 402. Then, the electric push rod 601 drives the folding bracket 602 to move upwards. The cleaning brush roller 609 is moved to penetrate into the discharge pipe 402. Driven by the drive motor 608, the cleaning brush roller 609 begins to rotate and cleans the inner wall of the discharge pipe 402. As the cleaning brush roller 609 rotates inside the discharge pipe 402, the part of the slurry adhering to the inner wall of the discharge pipe 402 is scraped off, effectively solving the problem that some slurry easily clumps at the discharge port of the grouting cylinder and causes blockage, affecting road construction operations. After cleaning, the cleaning brush roller 609 returns to its original position, and then the water valve 503 is activated to allow the clean water inside the cleaning water tank 5 to flow out through the cleaning water pipe 501 and spray onto the brush of the cleaning brush roller 609 through the spray head 502 to clean the cleaning brush roller 609.
