[0002] Pipe jacking is a trenchless construction method mainly used for laying pipes underground. This method mainly relies on the jacking force generated by the jacking equipment to overcome the friction between the pipe and the surrounding soil and push the pipe into the soil according to the designed slope. During the construction process, after one section of the pipe is pushed into the soil layer, the second section of the pipe is pushed in until the entire pipe is buried. The characteristics of this method are that it reduces the damage to the ground and improves the quality of the project and the construction efficiency.

[0003] Since pipe jacking construction does not require excavation of the surface layer and can cross roads, railways, rivers, ground buildings, underground structures and various underground pipelines, it is widely used in various underground projects. However, in the pipeline laying construction, it is inevitable to adjust the pitch slope of the pipeline according to the geological environment. At present, the slope adjustment of the pipe jacking construction guide rail is mostly achieved by pouring concrete at one end of the guide rail, which is not convenient to operate. For this reason, the present application proposes a pipe jacking construction guide rail with adjustable slope. Utility Model Content

Through this structural method, the first support frame 2 and the second support frame 3 can horizontally support the two guide rail bodies 1 for horizontal jacking construction. The sliding cooperation between the third support frame 4 and the adjusting groove 5 on the guide rail body 1 can realize the adjustment of the pitch slope of the guide rail body 1. Specifically, since the adjusting groove 5 gradually tilts downward from the middle of the guide rail body 1 to both ends, when the third support frame 4 approaches the first support frame 2 and moves along the adjusting groove 5, the upward slope of the guide rail body 1 is adjusted. When the third support frame 4 moves along the adjusting groove 5, the downward slope of the guide rail body 1 is adjusted. It has high flexibility and is convenient for jacking construction with different slope requirements.

[0026] As a preferred implementation manner of this embodiment, the first support frame 2 and the second support frame 3 both include a first mounting plate 7 and a first axial support 8 fixed to the upper surface of the first mounting plate 7. A pair of first axial supports 8 are provided, and the ends of the guide rail body 1 are assembled on the first axial supports 8. First mounting holes 9 are provided at both ends of the first mounting plate 7. The first mounting plates 7 are fixed by using the first mounting holes 9, so that the two first support frames 2 can be stably supported.

[0027] As a preferred implementation manner of this embodiment, the end of the guide rail body 1 is rotatably connected to the first axis support 8 to facilitate the pitch angle adjustment of the guide rail body 1. The third support frame 4 includes a second mounting plate 10 and a second axis support 11 fixed on the upper surface of the second mounting plate 10. The second axis support 11 is provided in pair, and the pair of second axis supports 11 are slidably matched with the adjustment groove 5. Specifically, the adjustment groove 5 passes through the guide rail body 1 horizontally, and an axis rod 12 is connected between a pair of second axis supports 11. The axis rod 12 passes through the adjustment groove 5, and the pitch slopes of the two guide rail bodies 1 are adjusted by sliding the axis rod 12 along the adjustment groove 5. When the axis rod 12 and the second mounting plate 10 move along the adjustment groove 5 close to the first support frame 2, the upward slope of the guide rail body 1 is adjusted. When the axis rod 12 and the second mounting plate 10 move along the adjustment groove 5 close to the second support frame 3, the downward slope of the guide rail body 1 is adjusted. After the adjustment of the axis rod 12 and the second mounting plate 10 is completed, when the upward slope is adjusted, the first mounting plate 7 in the second support frame 3 is fixed in the working well, and when the downward slope is adjusted, the first mounting plate 7 in the first support frame 2 is fixed in the working well, so that the guide rail body 1 can be supported and installed with an adjustable pitch slope.

[0028] Furthermore, an arc-shaped positioning groove 17 is opened on the inner top wall of the adjustment groove 5, and a plurality of positioning grooves 17 are opened at equal intervals along the inner top wall of the adjustment groove 5. When the shaft rod 12 slides and adjusts along the adjustment groove 5, it can be embedded in the positioning groove 17, which is beneficial to the stable support of the guide rail body 1.

[0029] Furthermore, lifting mechanisms 6 are provided at both ends of the first mounting plate 7 in the second support frame 3, and the lifting mechanisms 6 include L-shaped fixing plates 13 arranged at both ends of the first mounting plate 7 and a jack 14 arranged on one side of the L-shaped fixing plate 13, the telescopic end of the jack 14 is hinged to the top wall of the L-shaped fixing plate 13, and the bottom end of the jack 14 is hinged to an auxiliary support 15, and a second mounting hole 16 is opened on the auxiliary support 15. Before adjusting the pitch slope of the guide rail body 1, the jack 14 is started to push the L-shaped fixing plate 13 to lift the corresponding first mounting plate 7, and the guide rail body 1 is lifted and tilted by utilizing the hinge between the two ends of the guide rail body 1 and the first shaft support 8, and the hinge between the jack 14 and the auxiliary support 15 and the L-shaped fixing plate 13. At this time, the second mounting plate 10 and the shaft rod 12 are not subjected to force, so that the shaft rod 12 can slide and adjust along the adjustment groove 5.

[0030] During use, when horizontal pipe jacking construction is required, the first mounting plates 7 in the first support frame 2 and the second support frame 3 are fixed on the same plane in the working well. At this time, the first support frame 2 and the second support frame 3 cooperate to horizontally support the two guide rail bodies 1 for horizontal pipe jacking construction. When pipe jacking construction is required at a certain slope, the first mounting plate 7 is no longer fixed, the auxiliary support 15 is fixed, and the jack 14 is started to push the L-shaped fixing plate 13 to lift the corresponding first mounting plate 7. The guide rail body 1 is lifted and tilted by utilizing the hinge connection between the two ends of the guide rail body 1 and the first shaft support 8, as well as the hinge connection between the jack 14, the auxiliary support 15 and the L-shaped fixing plate 13. At this time, the second mounting plate 10 is pushed to drive the shaft rod 12 to slide along the adjustment groove 5, and the second mounting plate 10 and the shaft rod 12 are adjusted to be in the position of the adjustment groove 5. , since the adjustment groove 5 gradually tilts downward from the middle of the guide rail body 1 to both ends, when the shaft rod 12 and the second mounting plate 10 move along the adjustment groove 5 close to the first support frame 2, the upward slope of the guide rail body 1 is adjusted, and when the shaft rod 12 and the second mounting plate 10 move along the adjustment groove 5 close to the second support frame 3, the downward slope of the guide rail body 1 is adjusted. After the shaft rod 12 and the second mounting plate 10 are adjusted, the jack 14 is retracted to fix the second mounting plate 10 to the mounting surface of the working well, and when the upward slope is adjusted, the first mounting plate 7 in the second support frame 3 is fixed in the working well, and when the downward slope is adjusted, the first mounting plate 7 in the first support frame 2 is fixed in the working well, thereby the guide rail body 1 can be supported and installed with an adjusted upward and downward slope to perform pipe jacking construction according to the set angle.
