[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The assembled culvert anti-seepage connection device includes a culvert body, which includes a plurality of culvert segments 1 connected in series and connected front and back. A connection frame 5 is provided between each group of culvert segments 1. A rubber ring is fixedly connected to the inner wall of the connection frame 5. A butt joint 2 is fixedly connected to one end of the culvert segment 1. A butt joint slot 11 adapted to the butt joint 2 is provided at the other end of the culvert segment 1. The butt joint 2 is cylindrical. The two culvert segments 1 are connected front and back by inserting the butt joint 2 at one end of the rear culvert segment 1 into the joint slot 11 at one end of the front culvert segment 1.

[0024] Please refer again Figure 1 , Figure 2 and Figure 3A sliding groove 22 is provided on the butt joint 2, and a sliding block 21 is slidably connected inside the sliding groove 22. A fixed groove 12 corresponding to the sliding block 21 is provided on the inner wall of the joint slot 11. One end of the sliding block 21 is inserted into the interior of the fixed slot 12. A first spring 23 is installed inside the sliding groove 22. The first spring 23 is fixedly connected between the bottom of the sliding block 21 and the inner bottom wall of the sliding groove 22. One end of the sliding block 21 is inclined. When the butt joint 2 is inserted into the interior of the culvert segment 1, one end of the sliding block 21 is squeezed by the joint slot 11 to push the sliding block 21 to slide into the interior of the sliding groove 22. When one end of the sliding block 21 passes through the fixed slot 12, the first spring 23 rebounds and drives the sliding block 21 to be quickly inserted into the interior of the fixed slot 12, thereby completing the rapid combination connection between the two culvert segments 1.

[0025] Please refer again Figure 1 and Figure 2 One end of the culvert segment 1 is fixedly connected to a rubber waterstop strip 3, and the other end of the culvert segment 1 is provided with a mounting groove 4 adapted to the rubber waterstop strip 3. When the two culvert segments 1 are assembled front and back, the rubber waterstop strip 3 is inserted into the mounting groove 4 to achieve a waterproof effect on the connection between the two culvert segments 1.

[0026] Please refer again Figure 1 , Figure 2 and Figure 5 A rotating rod 6 is hinged on the culvert segment 1 through a pin shaft, a sliding sleeve 7 is installed at one end of the rotating rod 6, and a connecting cross bar 71 is fixedly connected to one end of the sliding sleeve 7. A T-shaped groove 51 is opened on the connecting frame 5, and one end of the sliding sleeve 7 and the connecting cross bar 71 are installed inside the T-shaped groove 51. The sliding sleeve 7 and the connecting cross bar 71 are arranged in a T shape, and one side of the connecting cross bar 71 is in tight contact with the T-shaped groove 51. The connecting frame 5 is installed between the connection points of the two culvert segments 1 to wrap and close the connection points of the two culvert segments 1. The sliding sleeve 7 and the connecting cross bar 71 are rotated by rotating the rotating rod 6 to rotate into the interior of the T-shaped groove 51, and the connecting cross bar 71 is in tight contact with the T-shaped groove 51 to complete the quick connection between the two culvert segments 1 and the connecting frame 5.

[0027] Please refer again Figure 1 , Figure 2 and Figure 5 The sliding sleeve 7 is slidably connected to one end of the rotating rod 6, and a fixed baffle 61 is fixedly connected to one end of the rotating rod 6. A second spring 62 is sleeved on the rotating rod 6, and the second spring 62 is arranged at the bottom of the fixed baffle 61. Under the action of the elastic force of multiple groups of second springs 62, the two culvert segments 1 are pulled tightly against each other. A limiting strip 8 is fixedly connected to the culvert segment 1, and the connecting frame 5 is in tight contact with the limiting strip 8. The multiple groups of limiting strips 8 are provided to enable the connecting frame 5 to play a limiting role during the installation process.

[0028] Working principle: The culvert segment 1 is cast and prefabricated and transported to the site. When in use, a connection frame 5 is first installed between the two culvert segments 1, and then the two culvert segments 1 are butted end to end. The butt joint 2 at one end of the rear culvert segment 1 is inserted into the joint slot 11 at one end of the front culvert segment 1 to complete the front-to-back butt joint of the two culvert segments 1. During the process of inserting the butt joint 2 into the joint slot 11, one end of the sliding block 21 is squeezed by the joint slot 11 to push the sliding block 21 to slide into the sliding groove 22. When one end of the sliding block 21 passes through the fixed slot 12, the sliding block 21 is driven by the rebound of the first spring 23. The block 21 is quickly inserted into the interior of the fixed slot 12 to complete the rapid assembly connection between the two culvert segments 1. Under the action of the rubber water stop strip 3 and the installation groove 4, the waterproof effect of the connection is improved. Then, the sliding sleeve 7 is pulled to slide on one end of the rotating rod 6, and the rotating rod 6 is rotated to make the sliding sleeve 7 and the connecting cross bar 71 rotate into the interior of the T-shaped groove 51. Under the action of the elastic force of the second spring 62, one end of the sliding sleeve 7 and the connecting cross bar 71 are pressed against the connecting frame 5 to complete the installation and fixation of the connecting frame 5. Under the action of the connecting frame 5, the exposed connection of the two culvert segments 1 is wrapped and closed, thereby improving the anti-seepage effect of the device.
