[0002] Pipe jacking construction in the ground is a trenchless construction method, which is a pipeline laying construction technology with little or no excavation. Among them, pipe jacking method construction is to generate jacking force by means of jacking equipment in the working pit, overcome the friction between the pipeline and the surrounding soil, jack the pipeline into the soil according to the designed slope, and transport the soil away. After one pipe is jacked into the soil layer, the second pipe is lowered and the jacking continues. Its principle is to use the thrust of the main jacking cylinder and the relay jacking between pipes to push the tool pipe or tunneling machine from the working pit through the soil layer and hoist it in the receiving pit. The pipeline follows closely behind the tool pipe or tunneling machine and is buried between the two pits.

[0026] Referring to Figures 1 to 7 shown, the present utility model provides a technical solution: an underground sewage pipe network jacking device for tunneling, including a support plate 1, the right end of the upper surface of the support plate 1 is fixedly connected with a fixed plate 2, and four cylinders 3 are installed on the surface of the fixed plate 2. The output ends of the four cylinders 3 are fixedly connected with a pushing ring plate 4. The lower surface of the support plate 1 is provided with an adjusting component 6. The adjusting component 6 includes a sliding frame 601, a bi-directional screw frame 602, a motor 603 and a slide rod frame 604. And a support arc plate 5 for supporting the pipeline is arranged at the upper end of the adjusting component 6. One end of the support plate 1 away from the fixed plate 2 is provided with a guiding component 9. The guiding component 9 includes a mounting plate 901. The two ends of the mounting plate 901 are slidably connected with a push rod 902. And one end of the push rod 902 is fixedly connected with a guiding plate 903.

[0027] Referring to Figure 1 、 Figure 3 and Figure 5As shown in the figure, in this embodiment: The upper ends of the two sliding frames 601 are fixedly connected to the lower surfaces of the two support arc plates 5, and both ends of the two sliding frames 601 are slidably connected with sliding rod frames 604, and the upper ends of the sliding rod frames 604 are fixedly connected to the lower surface of the support plate 1. A bidirectional screw rod frame 602 is threadedly connected to the middle of the sliding frame 601. The upper end of the bidirectional screw rod frame 602 is fixedly connected to the lower surface of the support plate 1, and a motor 603 is installed at one end of the bidirectional screw rod frame 602. When it is necessary to lift pipes with different diameters, the motor 603 can be turned on. The output end of the motor 603 drives the bidirectional screw rod frame 602 to rotate. At the same time, the sliding frame 601 moves along the surface of the sliding rod frame 604 by means of the thread, so that the support arc plates 5 at the upper ends of the sliding frames 601 approach each other, thereby adjusting the distance between the two support arc plates 5 to support pipes with different diameters and enhancing the practicability of the device. The lower end of the mounting plate 901 is fixedly connected to the upper surface of the support plate 1. A limiting spring 904 is provided between the push rod 902 and the mounting plate 901, and one end of the limiting spring 904 is fixedly connected to the side wall of the mounting plate 901. A plurality of guide wheels 905 are fixedly connected to one side of the guide plate 903. When the pipe moves, the guide wheels 905 on the two side guide plates 903 can guide and limit the pipe, avoiding the position deviation of the pipe during the docking process. At the same time, the pipe will push the guide plate 903 to move towards the direction close to the mounting plate 901 and squeeze the limiting spring 904, thereby guiding and limiting pipes with different diameters and improving the applicable range of the device.

[0028] Referring to Figure 4 、 Figure 6 and Figure 7 As shown, specifically, T-shaped sliders 8 are fixedly connected to both sides of the sliding frame 601, and the surface of the T-shaped sliders 8 is slidably connected with a slide rail frame 7. The lower end of the slide rail frame is fixedly connected to the upper surface of the support plate 1. By arranging the slide rail frame 7 and the T-shaped sliders 8 on both sides of the sliding frame 601, when the sliding frame 601 moves and adjusts, the T-shaped sliders 8 can play a role in limiting the sliding frame 601 to prevent the sliding frame 601 from shaking during movement and enhancing the stability of the device. Rotating grooves 10 are formed on the surface of the support arc plate 5, and auxiliary wheels 11 are rotatably connected to the inner walls of the rotating grooves 10. The rotating grooves 10 and the auxiliary wheels 11 are both provided in multiple groups and are evenly distributed on the surface of the support arc plate 5. By arranging the rotating grooves 10 and the auxiliary wheels 11 on the surface of the support arc plate 5, when the push ring plate 4 pushes the pipe to move, the sliding friction between the surface of the pipe and the surface of the support arc plate 5 can be changed into rolling friction, reducing the frictional resistance, so that the pipe can be pushed more smoothly and the working efficiency can be improved.

[0029] Working principle: When in use, first start the motor 603. The output end of the motor 603 drives the bidirectional screw to rotate. At the same time, the sliding frame 601 moves on the surface of the slide bar frame 604 by means of the thread, so that the support arc plates 5 at the upper end of the sliding frame 601 approach each other, thereby adjusting the distance between the two support arc plates 5 to support pipes with different diameters. When the sliding frame 601 is moving, the T-shaped sliders 8 on both sides can play a limiting role to prevent the sliding frame 601 from shaking during movement and enhance the stability of the device. After the two support arc plates 5 are adjusted, place the pipe on the surface of the support arc plate 5, and push the pipe to move on the surface of the support arc plate 5 through the cylinder 3 and the pushing ring plate 4. When the pipe is moving, through the auxiliary wheels 11 on the surface of the support arc plate 5, the sliding friction between the surface of the pipe and the surface of the support arc plate 5 can be transformed into rolling friction, reducing the frictional resistance, so that the pipe can be pushed more smoothly. When the pipe is moving, through the guide wheels 905 on the two guide plates 903, the pipe can be guided and limited to prevent the position of the pipe from shifting during the docking process. At the same time, the pipe will push the guide plate 903 to move towards the direction close to the mounting plate 901 and compress the limit spring 904, thereby guiding and limiting pipes with different diameters and improving the application range of the device.
