Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0021] As shown in the attached Figures 1 to 3 A waterproof and anti - detachment grouting pipe structure, including a pipe body 1 made of metal material to ensure sufficient strength and pressure resistance, playing a role in supporting and sealing to prevent slurry leakage. There are convex ribs 2 arranged on the inner wall of the pipe body 1. There are several groups of convex ribs 2, and each group of convex ribs 2 is evenly arranged along the circumferential direction of the inner wall of the pipe body 1. The shape, size and spacing of the convex ribs 2 are designed according to actual engineering requirements to optimize the stirring effect and prevent precipitation. The convex ribs 2 generate an additional turbulent effect during the slurry flow process, which helps to further disperse the particles in the slurry and improve the mixing uniformity. A waterproof layer 3 is arranged on the outer wall of the pipe body 1. Since the waterproof layer 3 can effectively prevent the slurry from leaking out, it avoids the pollution of the surrounding soil and groundwater by the slurry, which is beneficial to environmental protection. At the same time, it also reduces the waste of slurry and lowers the engineering cost.

[0022] One end of the pipe body 1 is provided with a first connecting flange 4, and a second connecting flange 5 is arranged above the first connecting flange 4. Both the first connecting flange 4 and the second connecting flange 5 are made of alloy steel material, which can provide sufficient strength and durability to ensure the stability and reliability of the connection part under high pressure and complex working conditions. The second connecting flange 5 is connected to the grouting pump. The cross - sectional shapes and sizes of the first connecting flange 4 and the second connecting flange 5 are the same. This design makes the gap between the first connecting flange 4 and the second connecting flange 5 smaller when they are combined, and it is not easy for the slurry to leak from the grouting pump into the pipe body 1. There are connecting holes 6 arranged on the outer walls of the first connecting flange 4 and the second connecting flange 5. There are four groups of connecting holes 6, and the four groups of connecting holes 6 are evenly arranged along the circumferential direction of the first connecting flange 4 and the second connecting flange 5. Since the connecting holes 6 make the connection part of the structure simple, easy to disassemble and replace, it is convenient for daily maintenance and repair, which helps to extend the service life of the equipment and reduce the long - term operation cost.

[0023] A locking mechanism 7 is provided in the connection hole 6. The locking mechanism 7 simplifies the installation process. Only by inserting the bolt 10 into the L-shaped slot 12 and rotating it to fix can the connection be completed. Compared with traditional connection methods such as threaded connection, the installation efficiency is greatly improved. At the same time, the locking mechanism 7 can ensure the stable connection of the pipe body 1 under harsh working conditions such as high pressure and vibration, reducing the accident risk caused by connection loosening or falling off. A sealing cover 8 is provided at the bottom of the pipe body 1. By using the sealing cover 8 in cooperation with the sealing ring 17, the bottom of the pipe body 1 can be effectively sealed to prevent the leakage of liquids such as slurry or groundwater, which helps to maintain the stability of the grouting pressure and prevent environmental pollution. Embodiment 2

[0024] Based on Embodiment 1, the solution in Embodiment 1 will be further refined and introduced in combination with the following specific working methods, as Figures 1 to 3 shown, see the following description for details:

[0025] As a preferred embodiment, the waterproof layer 3 is made of polymer cement-based aggregate, and the waterproof layer 3 is coated on the entire surface of the pipe body 1. Further, this polymer cement-based aggregate has excellent waterproof performance, which can effectively block the infiltration of groundwater or other liquids into the interior of the pipe body 1, and the process of coating the polymer cement-based aggregate on the entire surface of the pipe body 1 is relatively simple, without complex equipment or technology, facilitating rapid construction and popularization and application.

[0026] As a preferred embodiment, threads 9 are provided on the inner wall of the second connecting flange 5, and the second connecting flange 5 is connected to the grouting pump through the threads 9. Further, this design realizes the tight coupling between the two. The threads 9 have self-locking properties, which can maintain the stability of the connection under harsh conditions such as high pressure and vibration, avoiding connection loosening or leakage.

[0027] As a preferred embodiment, the locking mechanism 7 includes a bolt 10, a seat 11, an L-shaped slot 12, a contact plate 13 and a spring 14. The bolt 10 passes through the connection hole 6 of the second connecting flange 5 and is connected to the seat 11, and the seat 11 is arranged in the connection hole 6 of the first connecting flange 4. An L-shaped slot 12 is provided on the outer wall of the seat 11, and a contact plate 13 is arranged inside the seat 11, and a spring 14 is arranged on one side of the contact plate 13. Further, the bolt 10 is rod-shaped, and the seat 11 is arranged in the connection hole 6 of the first connecting flange 4 for fixing the bolt 10. Through this design, rapid locking and unlocking operations are allowed. Only by moving the convex block 16 on the bolt 10 to the corresponding position of the L-shaped slot 12 can the operation be completed, without additional tools or complex steps, and at the same time, it has high anti-disconnection performance.

[0028] As a preferred embodiment, a handle 15 is provided on one side of the bolt 10, and a convex block 16 is provided on the other side of the bolt 10. The bolt 10 moves in the L-shaped slot 12 through the convex block 16, so that the contact plate 13 compresses the spring 14 under the drive of the bolt 10 to fix the bolt 10 in the card seat 11. Further, the shape of the convex block 16 is the same as that of the L-shaped slot 12, enabling the operator to control the displacement of the convex block 16 in the L-shaped slot 12 through the handle 15, thereby locking the bolt 10 with the card seat 11. After locking, the bolt 10 is firmly fixed in the card seat 11 by the clamping force of the contact plate 13 and the spring 14, and is not easily loosened due to vibration, tensile force or other external forces, which enhances the stability and safety of the entire connection structure.

[0029] As a preferred embodiment, a sealing ring 17 is provided inside the sealing cover 8. Further, the sealing ring 17 is made of rubber material. The sealing ring 17 fills the gap between the sealing cover 8 and the pipe body 1, forming a reliable sealing barrier, which can effectively prevent the leakage of slurry, groundwater or other liquids from the connection, ensuring the tightness and efficiency of the grouting process.

[0030] The working process of the present utility model is as follows: First, the first connecting flange 4 and the second connecting flange 5 are respectively installed at both ends of the pipe body 1. Connecting holes 6 are provided on both of these connecting flanges for fixing and connecting. Then, a grouting pump is connected above the second connecting flange 5 through a thread 9. At the same time, the bolt 10 passes through the connecting hole 6 of the second connecting flange 5 and is connected to the card seat 11. The convex block 16 on the bolt 10 displaces along the L-shaped slot 12 of the card seat 11, and at the same time, the contact plate 13 compresses the spring 14 under the drive of the bolt 10. Then, the convex block 16 is driven by the contact plate 13 to be inserted into the inside of the L-shaped slot 12, so that the bolt 10 is firmly fixed in the card seat 11. A sealing cover 8 is installed at the bottom of the pipe body 1, and a sealing ring 17 is provided inside the sealing cover 8 to enhance the sealing performance. The sealing cover 8 is fixed to the pipe body 1 by means of thread connection or other means to ensure tightness. During the grouting process, the convex rib 2 prevents the slurry from precipitating on the inner wall of the pipe body 1, maintaining the fluidity and stability of the slurry. The above is the working principle of the waterproof and anti-loosening grouting pipe structure.
