DETAILED DESCRIPTION

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings, wherein the same components are indicated by the same reference numerals.

[0026] A large diameter corrugated pipe culvert anti-deformation reinforcement device, such as Figure 1 and Figure 2 As shown, it includes a pair of outer rings 1 and a pair of inner rings 2 placed inside the outer rings 1. The pair of outer rings 1 are fixedly connected in parallel by a number of outer ring connectors 15, and the pair of inner rings 2 are fixedly connected in parallel by a number of inner ring connectors 14. The outer rings 1 and the inner rings 2 are slidably connected by a slide rail 16. The maximum diameter of the inner ring 2 is smaller than the minimum diameter of the outer ring 1. The slide rail 16 can be fixed on both the outer ring 1 and the inner ring 2. The slide rail 16 allows the inner ring 2 and the outer ring 1 to rotate only around a common axis, limiting the degrees of freedom in other directions. A number of ratchet teeth 10 are provided on the side of the outer ring 1 close to the inner ring 2, and a pawl 11 corresponding to the ratchet teeth 10 is provided on the side of the inner ring 2 close to the outer ring 1. A pawl shaft 13 fixed to the inner ring 2 is provided on the end of the pawl 11 away from the ratchet teeth 10. The pawl 11 can rotate axially around the pawl shaft 13. A spring 12 is provided on the side of the pawl 11 away from the ratchet teeth 10, and the other end of the spring 12 is fixed to the inner ring 2. Fig.11 As shown, the ratchet structure can ensure that the inner ring 2 is fixed and stuck in one direction. When the reinforcement support achieves the best effect, the reinforcement device is kept from deforming, the stability of the structure is maintained, and a better support effect is achieved. The ratchet teeth 10, pawl 11, spring 12 and pawl shaft 13 are an integral structure. Several groups are set between the inner ring 2 and the outer ring 1, and they are evenly distributed, so that the ratchet structure is more evenly stressed, better preventing the inner ring 2 from rotating, and thus playing a better supporting role. A V-shaped lever 3 is set between a pair of outer rings 1, such as Figure 3As shown, the thickness of the V-shaped lever 3 is less than that of the outer ring connector 15. The outer ring 1 is also provided with a plurality of equally spaced mounting holes 7. A V-shaped lever shaft 5 is installed in each mounting hole. The V-shaped lever shaft 5 passes through the tip of the V-shaped lever 3. The V-shaped lever 3 can rotate axially around the V-shaped lever shaft 5. The V-shaped lever is provided with a sliding convex shaft 8 protruding to both sides at one end close to the inner ring 2. The inner ring 2 is provided with radial strip holes 9 at positions corresponding to the sliding convex shaft 8. The other end of the V-shaped lever 3 is connected to the tube wall support 4 through the tube wall support shaft 6. The tube wall support 4 can rotate axially around the tube wall support shaft 6. Figure 4 As shown in FIG. 1 , it is a schematic diagram of the structure of the anti-deformation reinforcement device when it is unfolded after axial rotation. As the ratchet structure drives the inner ring 2 to rotate, the pipe wall support member 4 is driven to adjust the diameter of the reinforcement device as a whole, so that it matches the inner diameter of the reinforced large-diameter corrugated pipe culvert. Figure 5 As shown, the installation accuracy is higher, which can prevent the pipe wall from being damaged, deformed and cracked due to uneven settlement of the foundation in the high fill area.

[0027] In order to save more effort during installation, Figure 6 and Figure 7 As shown, the inner ring 2 is provided with a gear shaft 17 passing through a pair of parallel inner rings 2, one end of the gear shaft 17 is provided with a gear wrench 18 axially perpendicular to the gear shaft 17, a gear 19 fixed to and coaxial with the gear shaft 17 is provided between the pair of parallel inner rings 2, the thickness of the gear 19 is less than the thickness of the inner ring connecting member 14, and a rack 20 matching the gear 19 is fixed between the pair of outer rings 1, and the rotation of the inner ring is achieved with a smaller force through a lever structure.

[0028] like Figure 8 As shown, a tube wall support plate 21 is fixedly provided on the tube wall support member 4. Fig. 9 As shown, the two anti-deformation reinforcement device modules together form a working group, so that the reinforcement device has a larger contact area with the pipe wall, and has a better support effect. Under the same pressure, the pressure generated becomes smaller, and the pipe wall is less likely to be deformed by the support structure, so the support purpose is better achieved. Fig.10 As shown, a flexible gasket 22 is provided on the other side where the tube wall support plate 21 is connected to the tube wall support member 4, such as rubber, TPU material, etc., to further firmly combine the tube wall support member 4 with the tube wall to prevent sliding.

[0029] The reinforcement device is composed of several groups of devices parallel to each other, each group is connected by a pipe wall support plate 21, and multiple groups of support increase the support length and area of ​​the entire corrugated pipe culvert and increase the stability of the support. In addition, compared with the traditional reinforcement structure, the hollow design in the middle does not affect the passage of other large-diameter objects in the corrugated pipe culvert, ensuring the use effect of the large-diameter corrugated pipe culvert.

[0030] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
