[0002] There are four common pipe jacking construction techniques: hand excavation, earth pressure balance, air pressure balance, and water pressure balance. The latter three are mechanical pipe jacking, while hand excavation is manual pipe jacking. Manual pipe jacking is the earliest developed pipe jacking construction technique.

At the same time, the pipeline following the tool pipe or boring machine is buried between the two wells to realize the construction method of trenchless laying of underground pipelines. To implement manual pipe jacking, a working well and a receiving well are first established. When pouring the bottom plate in the working well, guide rails are laid at the same time, and a bracket-type lifting equipment is installed on the well surface for excavation.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:

[0032] See also Figure 1-7 As shown, the utility model is a guiding device for pipe jacking construction, comprising a base plate 15, a platform 7, and a support plate 1. A horizontal direction adjustment component for adjusting the horizontal position of the platform 7 is installed on the base plate 15. An inclination direction angle adjustment component for adjusting the inclination angle of the support plate 1 is installed between the platform 7 and the support plate 1. A horizontal angle adjustment component for adjusting the horizontal angle of the support plate 1 is installed between the platform 7 and the support plate 1. Two parallel guide rails 2 are installed on the upper surface of the support plate 1. A support plate 3 for supporting the pipe 16 is slidably connected to the two guide rails 2.

[0033] The horizontal adjustment component specifically includes two first electric cylinders 13 vertically arranged on the front and left sides of the platform 7, one group of first electric cylinders 13 is arranged along the X-axis direction, and the other group of first electric cylinders 13 is arranged along the Y-axis direction. A first chute 12 arranged transversely is provided at the front end of the platform 7. A first slider 21 is slidably connected in the first chute 12. The output end of the front first electric cylinder 13 is fixedly connected to the first slider 21. A second chute 14 arranged longitudinally is provided at the left end of the platform 7. A second slider 20 is slidably connected in the second chute 14. The output end of the left first electric cylinder 13 is fixedly connected to the second slider 20. This setting can drive the platform 7 to adjust its horizontal position and finally complete the position adjustment of the pipeline 16.

[0034] The horizontal angle adjustment assembly specifically includes a ball head rod 8, a fixed block 9, a servo motor 17 and a shaft gear 10. The ball head rod 8, the fixed block 9 and the shaft gear 10 are coaxially arranged. One end of the shaft gear 10 is rotatably connected to the platform 7 through a bearing. The fixed block 9 is fixed to the upper end of the shaft gear 10. The ball head rod 8 is fixed to the center of the lower surface of the support plate 1. The fixed block 9 is provided with a groove. The ball head of the ball head rod 8 is placed in the groove and fits with the fixed block 9. The servo motor 17 is fixedly mounted on the platform 7 through a motor mounting seat. The output shaft of the servo motor 17 is equipped with a gear that meshes with the shaft gear 10. When the servo motor 17 rotates, the support plate 1, including the weight of the clamping parts arranged on the support plate 1, will be pressed on the ball head rod 8 as a whole, providing a large pressure and friction force, and the friction force is greater than the gravity of the support plate 1 sliding down, so when the servo motor 17 drives the shaft gear 10 to rotate, it will drive the support plate 1 to rotate, thereby completing the adjustment of the horizontal angle of the pipeline 16.

[0035] The tilt direction angle adjustment component specifically includes two second electric cylinders 11 fixed on the front and left sides of the upper surface of the platform 7. A circular arc guide rail with the center line of the support plate 1 as the axis is fixed on the lower surface of the support plate 1. Two arc sliders are slidably mounted on the circular arc guide rail. The two arc sliders are hinged to the output ends of the two second electric cylinders 11 through a ball joint respectively. The ball head can rotate relative to each other in the fixed block 9, and the top of the ball head rod 8 and one group of the second electric cylinders 11 drive the support plate 1 to rotate along the X-axis direction, and the other group of the second electric cylinders 11 drives the support plate 1 to rotate along the Y-axis direction, thereby completing the adjustment of the tilt angle of the pipeline 16.

[0036] Among them, a pair of clamping devices are symmetrically fixed on both sides of the sliding direction of the support plate 3. The clamping device specifically includes a clamping seat 4, a clamping plate 5, and an electric push rod 6. The clamping seat 4 is fixedly connected to the support plate 3. The clamping plate 5 includes a guide cylindrical rod, a clamping head and a rectangular plate. The guide cylindrical rod passes through the clamping seat 4.

The side wall of the support plate 3 is fixedly connected with two clamping devices that can move toward or away from each other, which can clamp and fix the pipeline 16.

[0037] Among them, a roller 22 is installed at the bottom of the support plate 3. The roller 22 is rollingly connected to the upper surface of the support plate 1. When the pipeline 16 is pushed forward, the friction force on the guide rail can be reduced.

[0038] A specific application of this embodiment is:

[0039] Step 1: excavate the pipe well 19 according to the installation requirements of the pipe 16 to be installed. After the excavation of the pipe well 19 is completed, set up suspension equipment on the ground on both sides of the pipe well 19, install this equipment in the pipe well 19, and then install the pipe 16 jacking equipment.

[0040] Step 2: After the suspension equipment hoists the pipeline 16, the construction personnel place the pipeline 16 on the pallet 3, and then adjust the pipeline 16. The operator starts the first electric cylinder 13, and the two groups of first electric cylinders 13 drive the platform 7 to move, thereby completing the adjustment of the horizontal position of the pipeline 16.

[0041] Step 3, after the horizontal position adjustment of the pipeline 16 is completed, start the second electric cylinder 11, and the second electric cylinder 11 adjusts the angle of the support plate 1. This is a fine adjustment of the angle. The inclination angle of the support plate 1 is within 15°. Driven by the two groups of second electric cylinders 11, the support plate 1 will rotate around the fixed block 9 under the action of the ball head rod 8, thereby completing the adjustment of the inclination angle of the pipeline 16.

[0042] Step 4: After that, start the servo motor 17. Under the action of the servo motor 17, the support plate 1 is driven to rotate, thereby completing the horizontal adjustment of the pipeline 16 and aligning the pipeline 16 with the pipeline opening that needs to be jacked.

[0043] Step 5. After the angle of the pipe 16 is adjusted, start the jacking equipment to complete the jacking of the pipe 16. The jacking equipment includes a pipe jacking machine 18. The output end of the pipe jacking machine 18 will abut against the pipe 16. The pipe 16 will move toward the pipe mouth under the action of the guide rail 2, and will not deviate under the action of the clamping device. After the jacking of the pipe 16 is completed, repeat the above steps 2, 3 and 4 until the pipe 16 is penetrated.
