[0044] like Figures 1 to 4 As shown, the embodiment of the utility model provides a grouting machine, including a grouting machine body 100 and a grouting pipe assembly 200, wherein the grouting machine body 100 is provided with a feed port for grouting material to enter; the grouting pipe assembly 200 is connected to one side of the grouting machine body 100, and the grouting pipe assembly 200 includes a reversing pipe 210, a grouting pipe 220, and a connecting assembly 230 connecting the reversing pipe 210 and the grouting pipe 220, and the reversing pipe 210 is connected to the grouting machine body 100. The connecting assembly 230 includes a fixed sleeve 231 and a connecting insert ring 232, one end of the fixed sleeve 231 is fixedly connected to the reversing pipe 210, the other end of the fixed sleeve 231 is detachably connected to one end of the connecting insert ring 232, and the other end of the connecting insert ring 232 is connected to the grouting pipe 220.

[0045] The grouting machine provided by the utility model has a fixed connection between the reversing pipe 210 and the grouting machine body 100, which ensures that the grouting material can flow smoothly between the grouting machine body 100 and the grouting pipe 220. The design of the connecting assembly 230 provides convenience for the installation and removal of the grouting pipe 220.

[0046] Specifically, the fixed connection design between one end of the fixed sleeve 231 and the reversing tube 210 provides a stable and reliable connection point for the grouting assembly, ensuring the continuity and uniformity of the slurry flow during the grouting process. The other end of the fixed sleeve 231 and one end of the connecting plug ring 232 adopt a detachable connection design, which allows the staff to quickly remove or install the connecting plug ring 232. In actual use, it provides sufficient convenience for the installation and removal of the grouting pipe 220. For example, when the grouting pipe 220 needs to be replaced or maintained due to long-term use, the staff can easily disconnect the connection between the fixed sleeve 231 and the connecting plug ring 232. Afterwards, the connecting plug ring 232 is connected to the new grouting pipe 220. During this process, the staff can complete the operation in any posture they are accustomed to. In this way, it not only helps to improve the work efficiency of the staff, but also helps to enhance the regularity and stability of the connection between the grouting pipe 220 and the connecting plug ring 232.

[0047] The following will describe in detail the various parts of the grouting machine provided by the embodiment of the utility model in conjunction with the accompanying drawings:

[0048] like Figures 1 to 4As shown, the grouting machine provided by the utility model is mainly used in construction projects. By injecting slurry into the pores or cracks of the soil, the bearing capacity and stability of the soil are improved. It can be used for the reinforcement of construction sites, road foundations, bridge foundations, etc.

[0049] The grouting machine includes a grouting machine body 100 and a grouting pipe assembly 200, and the grouting pipe assembly 200 is connected to the grouting machine body 100. The grouting machine body 100 is the main structure of the grouting machine, and may include a grouting box. A feed port for grouting material to enter is provided on the grouting machine body 100. The number of the feed ports may be one or more, and different grouting materials (such as cement slurry, chemical slurry, etc.) can be smoothly introduced into the interior of the grouting machine. The design of the feed port needs to take into account the compatibility with the grouting material supply equipment, as well as the control of the material flow during the grouting process.

[0050] The grouting pipe assembly 200 is connected to one side of the grouting machine body 100. The grouting pipe assembly 200 includes a reversing pipe 210, a grouting pipe 220, and a connecting assembly 230 connecting the reversing pipe 210 and the grouting pipe 220. The reversing pipe 210 is connected to the grouting machine body 100. The reversing pipe 210 is mainly used to change the flow direction of the slurry inside the grouting machine. Through the reversing pipe 210, it can be determined whether the slurry enters the grouting pipe 220 or returns to the grouting machine body 100, or the flow direction of the slurry is changed to adapt to different grouting requirements. The reversing pipe 210 may include a reversing valve, and the staff can change the flow direction of the slurry by adjusting the reversing valve, adjust the grouting state, and complete the grouting operation.

[0051] The grouting pipe 220 is used to provide a circulation channel for the grouting material. A grouting head 260 may be provided on the grouting pipe 220, and the grouting liquid may flow out through the grouting head 260 to complete the grouting operation. The grouting pipe 220 is connected to the reversing pipe 210 through the connecting assembly 230. The connecting assembly 230 includes a fixed sleeve 231 and a connecting insert ring 232, one end of the fixed sleeve 231 is fixedly connected to the reversing pipe 210, the other end of the fixed sleeve 231 is detachably connected to one end of the connecting insert ring 232, and the other end of the connecting insert ring 232 is connected to the grouting pipe 220.

[0052] Specifically, the reversing tube 210 extends along the first direction X, and the fixed sleeve 231 is fixedly connected to one side of the reversing tube 210 in the second direction Y. The fixed sleeve 231 extends along the second direction Y, and the second direction Y is perpendicular to the first direction X. The fixed sleeve 231 can be connected to the reversing tube 210 by welding to improve the stability of the connection between the two. The other end of the fixed sleeve 231 can be detachably connected to the connecting plug ring 232 by plugging, threading or clamping.

[0053] like Figure 3As shown, in some embodiments of the utility model, the other end of the fixed sleeve 231 is connected to one end of the connecting plug ring 232 by plugging. Furthermore, the other end of the fixed sleeve 231 is provided with a mounting groove 2311, and one end of the connecting plug ring 232 is plugged into the mounting groove 2311. Preferably, a thread is also provided in the mounting groove 2311 of the fixed sleeve 231, and correspondingly, one end of the connecting plug ring 232 is also provided with a thread, and one end of the connecting plug ring 232 is plugged and threadedly connected in the mounting groove 2311. That is, the two are connected by plugging and threaded at the same time. This connection method not only realizes the detachable connection of the two parts, but also enhances the stability and firmness of the connection between the two, thereby ensuring the smooth progress of the grouting operation.

[0054] The grouting pipe 220 is connected to the other end of the connecting insert ring 232. Specifically, the connection mode of the grouting pipe 220 and the connecting insert ring 232 is not limited by the utility model. It can be connected to the connecting insert ring 232 by external tools such as iron wire, as long as the connection between the two can be completed. It should be noted that the grouting pipe 220 can be a disposable grouting pipe 220 or a repetitive grouting pipe 220. No matter which type of grouting pipe 220, it will be damaged after being used for a certain period of time. Therefore, the connection between the grouting pipe 220 and the connecting insert ring 232 is also detachable to facilitate the replacement of the grouting pipe 220.

[0055] In some embodiments of the utility model, the connecting plug ring 232 includes a connecting ring 2321 and a limiting plug ring 2322, one end of the connecting ring 2321 is detachably connected to the other end of the fixed sleeve 231, one end of the limiting plug ring 2322 is detachably connected to the other end of the connecting ring 2321, and the other end of the limiting plug ring 2322 is connected to the grouting pipe 220. In this embodiment, the other end of the fixed sleeve 231 is also provided with a mounting groove 2311, and one end of the connecting ring 2321 is inserted into the mounting groove 2311. Preferably, the mounting groove 2311 of the fixed sleeve 231 is also provided with a thread, and accordingly, one end of the connecting ring 2321 is also provided with a thread, and one end of the connecting ring 2321 is inserted and threadedly connected in the mounting groove 2311. This connection method provides a stable and firm connection, ensuring that the connecting ring 2321 will not loosen due to vibration or pressure during the grouting process.

[0056] The limiting insert ring 2322 is inserted into the connecting ring 2321, and a limiting structure is provided at the connection between the limiting insert ring 2322 and the connecting ring 2321, so that the limiting insert ring 2322 cannot rotate axially relative to the connecting ring 2321. The limiting structure ensures that the limiting insert ring 2322 cannot rotate axially relative to the connecting ring 2321, thereby providing precise positioning and control. Moreover, the design of the limiting structure prevents the accidental rotation or displacement of the limiting insert ring 2322, which is particularly important in grouting operations because it can prevent the grouting pipe 220 from being improperly moved or damaged, thereby improving the safety of the entire operation. In addition, since the connection method of the connecting ring 2321 and the limiting insert ring 2322 allows for quick disassembly and assembly, when the grouting pipe assembly 200 needs to be maintained or replaced, the staff can easily operate it, reducing maintenance time and cost.

[0057] Furthermore, the threaded connection within the mounting groove 2311, and the design of the limiting structure at the limiting insert ring 2322 and the connecting ring 2321 help to evenly distribute force and reduce stress concentration on a single component, thereby enhancing the durability and reliability of the entire grouting pipe assembly 200. Its stable connection and precise limiting control make the grouting process smoother and reduce grouting interruptions or reduced efficiency due to unstable connections or improper limiting.

[0058] Specifically, one of the inner wall of the connecting ring 2321 and the outer wall of the limiting insert ring 2322 is provided with a positioning groove 21a, and the other is provided with a limiting protrusion 22a that matches the shape and size of the positioning groove 21a, and the limiting protrusion 22a is inserted into the positioning groove 21a. The number of the positioning groove 21a and the limiting protrusion 22a can be multiple, and the multiple positioning grooves 21a can be evenly distributed circumferentially on the inner wall of the connecting ring 2321 or the outer wall of the limiting insert ring 2322, and correspondingly, the limiting protrusion 22a is evenly distributed circumferentially on the outer wall of the limiting insert ring 2322 or the inner wall of the connecting ring 2321.

[0059] Further, the grouting pipe 220 is connected to one side of the reversing pipe 210 in the second direction Y. The number of the grouting pipes 220 and the number of the connecting assembly 230 are both two, and the two grouting pipes 220 are axially symmetrical. The grouting pipe 220 includes a first segment 221 and a second segment 222, wherein one end of the first segment 221 is connected to the reversing pipe 210, and the first segment 221 extends along the second direction Y; one end of the second segment 222 is connected to the other end of the first segment 221, and the second segment 222 extends along the first direction X. The second segments 222 of the two grouting pipes 220 are connected to each other.

[0060] The grouting pipe assembly 200 further includes a connecting pipe 240 connected to the other side of the reversing pipe 210 in the second direction Y. The connecting pipe 240 is used to connect to an external pipeline. There are two connecting pipes 240, and the two connecting pipes 240 are axially symmetrical. The connecting pipe 240 can be used to connect the grouting machine with an external pipeline system, which is responsible for transporting the slurry from the slurry source to the grouting machine.

[0061] The grouting pipe assembly 200 further includes a sealing pipe 250, which is sealed and connected to the connection of the second segments 222 of the two grouting pipes 220. The grouting head 260 can be connected to the sealing pipe 250 and communicate with the grouting pipe 220. Furthermore, the grouting head 260 can also be connected to a pressure gauge 270 to facilitate the staff to check the grouting pressure during the grouting operation.

[0062] In some embodiments of the utility model, the grouting machine also includes a mobile cart 300 for carrying the grouting machine body 100, and a mobile wheel 311 is provided at the bottom of the mobile cart 300. The bottom of the mobile cart 300 can be equipped with a plurality of mobile wheels 311, which can be made of wear-resistant materials to ensure good load-bearing capacity and smooth mobility. The configuration of the mobile wheels 311 allows the grouting machine to move flexibly on different terrains, including the uneven ground commonly seen on construction sites. In addition, the cart is usually equipped with a push rod 320 or a handle that is easy to operate, so that the staff can easily push or pull the grouting machine and quickly move it to the designated working position.

[0063] In order to provide better steering flexibility, the mobile cart 300 may include a combination of directional wheels and rotating wheels so that the grouting machine can be accurately positioned at the location where grouting is required. In addition, in order to ensure the stability of the grouting machine during operation, the mobile cart 300 may also be equipped with a braking system that can fix the wheels to prevent the grouting machine from moving or sliding during operation.

[0064] In order to make the grouting machine adapt to the changing working environment, the design of the moving wheel 311 should be easy to replace and maintain, so as to reduce the possible failure and maintenance time in long-term operation. The utility model can quickly transfer the grouting machine from one working point to another by moving the cart 300, which significantly improves the construction efficiency of the project and the continuity of the grouting operation.
