[0021] Embodiment 1

[0022] like Figures 1 to 5 As shown, the utility model provides a back-stick waterstop pressing device in a high-speed railway tunnel, including a clamp end and a pressing end. The clamp end can clamp the pressing device on the main structural reinforcement 6 outside the concrete top surface 9 of the lining small side wall, and the pressing end can press the back-stick waterstop 7 tightly, so that the back-stick waterstop 7 and the waterproof board 8 are effectively and tightly attached to achieve a firm bonding effect.

[0023] The clamp end includes a first steel bar 1, which is 140 mm long and 20 mm in diameter. The first steel bar 1 provides support for the second steel bar 2 and the connecting sleeve 3. A second steel bar 2 is provided at the bottom of the first steel bar 1. The number of the second steel bars 2 is two. The two second steel bars 2 can be clamped on the outer structural main bars 6 of the lining of the small side wall, so that the clamp end is clamped with the structural main bars 6. The two second steel bars 2 are welded to the bottom of the first steel bar 1. The two second steel bars 2 are 50 mm long and 20 mm in diameter, and the two second steel bars 2 are 30 mm apart, so that the clamp end can be just clamped on the structural main bars 6, which is convenient for the top pressure device to tighten the back water stop 7, so that the back water stop 7 and the waterproof board 8 are effectively close to each other, achieving a strong bonding effect. A connecting sleeve 3 is provided on one side of the top of the first steel bar 1. The diameter of the inner ring of the connecting sleeve 3 is 20 mm. The connecting sleeve 3 is welded on the top of the first steel bar 1.

[0024] The top pressure end includes a threaded rod 4, the diameter of which is 20 mm. The threaded rod 4 can cooperate with the connecting sleeve 3, so that the fixture end and the top pressure end are movably connected, and one side of the threaded rod 4 is conveniently connected to the connecting sleeve 3 by threading, and the other side is connected to the top plate 5. The threaded rod 4 and the top plate 5 are connected by welding. Since the connecting sleeve 3 is fixedly connected to the fixture end, when the threaded rod 4 is rotated, the threaded rod 4 will drive the top plate 5 to move, which is convenient for adjusting the distance between the top plate 5 and the threaded rod 4, so that the top plate 5 can be pressed against the back waterstop 7. The top plate 5 is a square steel plate with a thickness of 4 mm and a side length of 100 mm, which is convenient for pressing the back waterstop 7, so that the back waterstop 7 and the waterproof board 8 are tightly fitted, firmly bonded, and not easy to debond. After the back waterstop 7 and the waterproof board 8 are firmly bonded, the top plate 5 can be separated from the back waterstop 7 by rotating the threaded rod 4, which can be recycled to reduce resource waste.

[0025] When using the back-sticking waterstop jacking device in a high-speed railway tunnel provided by the utility model, first clamp the first steel bar 1 and the two second steel bars 2 on the main structural bars 6, and then install the threaded rod 4 on the connecting sleeve 3 on the top of the first steel bar 1. After installation, rotate the threaded rod 4 to adjust the distance between the top plate 5 and the back-sticking waterstop 7, and the back-sticking waterstop 7 and the waterproof board 8 are effectively and tightly attached, so that the back-sticking waterstop 7 and the waterproof board 8 are firmly bonded. After the bonding is firm, the threaded rod 4 can be rotated to separate the top plate 5 from the back-sticking waterstop 7, so that the jacking device can be recycled and reduce resource waste.

[0026] Therefore, the utility model adopts the above-mentioned back-sticking waterstop pressing device in the high-speed railway tunnel, which is easy to install and easy to operate. Only by rotating the threaded rod, the distance between the top plate and the back-sticking waterstop can be adjusted, so that the back-sticking waterstop and the waterproof board can be effectively and closely attached, which saves labor and has higher work efficiency. The back-sticking waterstop and the waterproof board are firmly bonded and not easy to debond. The quality is guaranteed and it can be recycled, and the overall effect is remarkable.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
