[0032] Please see Figures 1-8 This utility model provides a technical solution: a pipeline concrete truss repair construction device, including a base 1, a movable frame 2, and a pipeline concrete truss 3, and a repair component. The repair component is set on the movable frame 2 and includes a concrete mixing tank 12, which is mounted on the movable frame 2. A concrete pump 13 is installed at the upper end of the movable frame 2. The inlet end of the concrete pump 13 is fixedly connected to a first concrete pipe 14, and the outlet end of the concrete pump 13 is fixedly connected to a second concrete pipe 15. A first grouting cover 4 and a second grouting cover 5 are fitted onto the surface of the pipeline concrete truss 3. The first grouting cover 5, the first grouting cover 4, and the second grouting cover 5 are fixed together by bolts. Both the first grouting cover 4 and the second grouting cover 5 are semi-circular shell structures. The upper end of the first grouting cover 4 is fixedly connected to the grouting pipe 6. The ends of the first concrete pipe 14 and the second concrete pipe 15 away from the concrete pump 13 are fixedly connected to the concrete mixing tank 12 and the grouting pipe 6, respectively. The inner wall of the first grouting cover 4 is fixedly connected to the first guide plate 10, and the inner wall of the second grouting cover 5 is fixedly connected to the second guide plate 11. Both the first guide plate 10 and the second guide plate 11 are spiral-shaped.

[0033] The repair component also includes a threaded groove 7, which is located at the upper end of the first grouting cover 4. A connecting pipe 8 is threaded inside the threaded groove 7, and a sealing bolt is threaded inside the threaded groove 7.

[0034] A feed pipe is fixedly connected to the upper end of the concrete mixing tank 12, and a discharge pipe is fixedly connected to the lower end surface of the concrete mixing tank 12.

[0035] The concrete mixing tank 12 is equipped with a mixer 16, which includes a drive motor, a rotating shaft, and two symmetrically arranged mixing blades fixed on the surface of the rotating shaft.

[0036] Two guide rails 17 are fixedly connected to the upper end of the base 1.

[0037] The lower end of the movable frame 2 is fixedly connected to a guide wheel bracket 18, and a guide wheel 20 is rotatably connected to the inner side of the guide wheel bracket 18. There are six sets of guide wheel brackets 18 and guide wheels 20, which are symmetrically arranged on both sides of the movable frame 2. The lower end of the movable frame 2 is provided with two drive motors 19, which are fixed on the corresponding guide wheel brackets 18. The output ends of the two drive motors 19 are fixedly connected to the corresponding guide wheels 20.

[0038] When using the device, firstly, the guide rail 17 on the base 1 provides a moving track for the movable frame 2; start the drive motor 19 at the lower end of the movable frame 2, and the drive motor 19 drives the guide wheel 20 to roll on the guide rail 17, thereby moving the movable frame 2 along the guide rail 17 and adjusting it to the position where the pipe concrete truss 3 needs to be repaired.

[0039] The concrete raw materials required for the repair are fed into the concrete mixing tank 12 through the feed pipe at the top of the tank; the mixer is started, and the drive motor of the mixer drives the shaft to rotate, and the mixing blades symmetrically arranged on the surface of the shaft rotate accordingly to mix the concrete raw materials in the tank and make them evenly mixed.

[0040] After mixing is completed, the concrete pump 13 is started; the concrete pump 13 sucks the mixed concrete in the concrete mixing tank 12 through the first concrete pipe 14, and then transports the concrete to the grouting pipe 6 through the second concrete pipe 15, and finally injects it into the closed space composed of the first grouting cover 4 and the second grouting cover 5. The two grouting covers are semi-circular shell structures and are fixed to the surface of the pipe concrete truss 3 by bolts, and are used to wrap the parts that need to be repaired.

[0041] During the grouting process, the first guide plate 10 on the inner wall of the first grouting cover 4 and the second guide plate 11 on the inner wall of the second grouting cover 5 play an important role. Since they are both spiral-shaped, the concrete will flow along the shape of the spiral guide plate when it is injected, so as to be more evenly distributed in the gap between the grouting cover and the pipe concrete truss 3, ensuring that the repair material can fully fill the damaged part and improve the repair effect.

[0042] Meanwhile, the operator can observe the grouting situation through the connecting pipe 8; the connecting pipe 8 is threaded into the threaded groove 7 at the upper end of the first grouting cover 4, and the progress of grouting and the filling status of concrete can be directly observed from the connecting pipe 8.

[0043] Once the grouting is observed to be complete and the concrete has been fully filled and achieved the desired effect, the operation of the concrete pump 13 is stopped. Subsequently, the threaded groove 7 is sealed with sealing bolts 9 to prevent concrete overflow or external impurities from entering. At this time, the first grouting cover 4 and the second grouting cover 5 will remain on the pipe concrete truss 3, which not only protects the internal repair concrete but also provides additional support and reinforcement to the pipe concrete truss 3 together with the repaired concrete, enhancing its structural strength and stability, and completing the entire pipe concrete truss repair construction process.

[0044] Furthermore, the installation of the first grouting cover 4 and the second grouting cover 5 not only enables grouting repair of the pipeline concrete truss 3, but also facilitates the guidance of the concrete during grouting through the use of the first guide plate 10 and the second guide plate 11. This allows the concrete to be more evenly distributed in the gap between the grouting cover and the pipeline concrete truss 3, ensuring that the repair material can fully fill the damaged area and improve the repair effect. At the same time, retaining the first grouting cover 4 and the second grouting cover 5 on the pipeline concrete truss 3 allows them to work together with the repaired concrete to provide additional support and reinforcement for the pipeline concrete truss 3, enhancing its structural strength and stability, and completing the entire pipeline concrete truss repair construction process.

[0045] The use of guide rail 17 and guide wheel 20 facilitates the movement of the device, allowing for flexible movement of the construction device and quick switching to different repair points. This ensures that the grouting operation accurately covers the damaged parts, avoids missed or incorrect repairs, reduces construction waiting time, and improves the efficiency of the device.

The first guide plate 10 and the second guide plate 11 on the inner wall guide the concrete. After grouting, they are retained on the pipe concrete truss 3 to provide additional support. This ensures that the grouting process is carried out in a closed space, so that the concrete is evenly distributed, fully fills the damaged parts, improves the repair effect, and enhances the structural strength of the pipe concrete truss 3.

[0050] Grouting pipe 6: connects the second concrete pipe 15 and the first grouting hood 4, and delivers concrete into the grouting hood; ensuring that the concrete can smoothly enter the gap between the grouting hood and the pipe concrete truss 3.

[0058] Agitator 16: includes a drive motor, a rotating shaft, and stirring blades;

[0059] The drive motor drives the rotating shaft to rotate, causing the mixing blades to rotate and mix the raw materials in the concrete mixing tank 12; thus ensuring that the concrete raw materials are fully mixed and guaranteeing the quality of the concrete.
