Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, specifically to a corrugated pipe culvert opening support structure and a corrugated pipe culvert. Background Technology

[0002] In infrastructure projects such as highways, municipal works, and railways, structures such as passageways and drainage culverts have long been constructed primarily using cement concrete. However, traditional cement culverts have many drawbacks, including susceptibility to cracking, poor frost resistance, long construction periods, and significant environmental pollution.

[0003] In recent years, to address these challenges, the engineering community has introduced corrugated steel pipe culverts as an innovative material and construction technique. This new structure is not only convenient to construct but also possesses excellent durability and damage resistance, significantly surpassing the performance of traditional cement culverts. Nevertheless, with the widespread application of corrugated steel pipe culverts, some new problems have emerged in engineering practice. Specifically, although the main structure of the culvert has been upgraded to corrugated steel plates, the culvert opening is currently reinforced only with a combination of wall panels and tie rods, making it difficult to guarantee the stable and durable use of the culvert opening.

[0004] Therefore, there is an urgent need for a support structure that can ensure the stability and durability of culvert openings, as well as corrugated pipe culverts. Summary of the Invention

[0005] The purpose of this utility model is to provide a corrugated pipe culvert opening support structure and a corrugated pipe culvert, so as to at least solve the current problem of unstable and durable use of corrugated pipe culvert openings.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A corrugated pipe culvert opening support structure includes an opening wall panel and multiple tie rods, as well as a support box, multiple steel mesh, an arched corrugated plate, and concrete; The support box has a reinforced cavity inside. The front and rear ends of the support box are provided with coaxially arranged mounting holes. The steel mesh is placed in the reinforced cavity. The arched corrugated plate is placed inside the support box and located below the mounting holes. The corrugated pipe culvert body passes through the mounting holes and is supported on the support box. The support box is provided with a plurality of first grouting holes and a second grouting hole that communicates with the interior of the arched corrugated plate. The concrete is poured into the reinforcing cavity and the arched corrugated plate through the first grouting holes and the second grouting holes, respectively.

[0007] Furthermore, the support box is rectangular and includes a bottom plate, two end plates, two side plates, and a top plate. The mounting holes are respectively opened on the two end plates, the first grouting hole is opened on the top plate, and the second grouting hole is opened on one of the end plates. The steel mesh is connected to the end plates and the side plates, and the bottom of the arched corrugated plate is set on the bottom plate.

[0008] Furthermore, the steel mesh is arranged horizontally and spaced vertically, and the ends of the steel mesh are respectively connected to the inner wall of the support box and the outer wall of the corrugated pipe culvert body.

[0009] Furthermore, both ends of the arched corrugated plate are connected to the end plates of the support box, and the bottom of the corrugated pipe culvert body is disposed on the arched corrugated plate.

[0010] Furthermore, long flanges are provided on both sides of the bottom of the arched corrugated plate. The long flanges are provided on the base plate, and a sealing strip is provided between the long flanges and the base plate.

[0011] Furthermore, auxiliary support components are provided on both sides below the corrugated pipe culvert body inside the support box. One end of the auxiliary support component is connected to the outer wall of the corrugated pipe culvert body, and the other end is connected to the bottom plate.

[0012] Furthermore, the auxiliary support assembly includes multiple support rods and corrugated steel pads. The corrugated steel pads are connected to the outer wall of the corrugated pipe culvert body. The support rods are arranged at intervals along the axial direction of the corrugated pipe culvert body, and the upper end of the support rod is connected to the corrugated steel pad, while the lower end is connected to the bottom plate.

[0024] Example 1: This embodiment provides a corrugated pipe culvert opening support structure, including an opening wall panel 7 and multiple tie rods 8, as well as a support box 1, multiple steel meshes 2, an arched corrugated plate 3, and concrete 4.

[0025] Specifically, the opening wall panel 7 includes a main wall panel 71, a bottom plate 72, a water-cutting wall panel 73, and two side wall panels 74. The two side wall panels 74 are respectively installed on both sides of the main wall panel 71 and are set at an obtuse angle to the main wall panel 71. The tie rod 8 is connected between the main wall panel 71 and the corrugated pipe culvert body 6, as well as between the bottom plate 72, the water-cutting wall panel 73, and the side wall panels 74 by bolts. The main wall panel 71, the bottom plate 72, the water-cutting wall panel 73, and the side wall panels 74 are fixedly connected by connectors 75 and bolts. In this embodiment, the connector 75 is a circular steel plate component.

[0026] The support box 1 is rectangular and includes a bottom plate 15, two end plates 16, two side plates 17 and a top plate 18. The bottom plate 15, end plates 16, side plates 17 and top plate 18 are all corrugated plates, which improves the strength and load-bearing capacity of the support box 1.

[0027] The support box 1 has a reinforced cavity 11 inside. The center of each of the two end plates 16 of the support box 1 is provided with a coaxially arranged mounting hole 12. The corrugated pipe culvert body 6 passes through the mounting hole 12 and is supported on the support box 1.

[0028] In this embodiment, the reinforcing mesh 2 is disposed in the reinforcing cavity 11. The reinforcing mesh 2 is arranged horizontally and aligned vertically. The ends of the reinforcing mesh 2 are welded to the end plate 16 and side plate 17 of the support box 1 and the outer wall of the corrugated pipe culvert body 6, respectively. The fixed connection between the reinforcing mesh 2 and the end plate 16 and side plate 17 further enhances the overall strength of the support box 1. When external forces act on the support box 1, the reinforcing mesh 2 can work together with the end plate 16 and side plate 17 to resist deformation, thereby ensuring the structural integrity of the support box 1. The ends of the reinforcing mesh 2 are connected to the troughs on the outer wall of the corrugated pipe culvert body 6. The ends of the reinforcing mesh 2 enter the troughs of the corrugated pipe culvert body 6, making the size of the reinforcing mesh 2 larger, thereby further enhancing the overall structural strength of the support box 1.

[0029] Specifically, the arched corrugated plate 3 is installed inside the support box 1 and located below the mounting hole 12. The bottom of the arched corrugated plate 3 is welded to the base plate 15. The front and rear ends of the arched corrugated plate 3 are welded to the front and rear end plates 16 of the support box 1, respectively. The bottom of the corrugated pipe culvert body 6 is supported on the top of the arched corrugated plate 3. The arched corrugated plate 3 provides a stable foundation support for the entire support box 1. Due to its unique arched structure, it can effectively disperse the pressure from above, so that the pressure is evenly transmitted to the base plate 15.

[0030] Furthermore, each of the bottom outer sides of the arched corrugated plate 3 is provided with a long flange 31. The length of the long flange 31 is consistent with the front and rear length of the arched corrugated plate 3. The long flange 31 is fixedly connected to the base plate 15 by high-strength bolts to ensure the stability of the arched corrugated plate 3 during use, and also to facilitate the installation and disassembly of the arched corrugated plate 3. In addition, a sealing strip is provided at the connection between the long flange 31 and the base plate 15, and the sealing strip is tightly attached between the long flange 31 and the base plate 15.

[0031] In this embodiment, a plurality of first grouting holes 13 are spaced apart on the top plate 18 of the support box 1, and a second grouting hole 14 connected to the interior of the arched corrugated plate 3 is opened on one end plate 16 of the support box 1. Concrete 4 is poured into the reinforcing cavity 11 and the arched corrugated plate 3 through the first grouting hole 13 and the second grouting hole 14 respectively. When concrete 4 is injected into the reinforcing cavity 11 from the first grouting hole 13, it can fill the gaps between the steel mesh 2, so that the steel mesh 2 and the support box 1 are better integrated into a whole, thereby improving the compressive strength of the support structure and preventing it from collapsing or sinking. When concrete 4 is injected laterally from the second grouting hole 14, it can be smoothly poured into the arched corrugated plate 3.

[0032] The bottom of the corrugated pipe culvert body 6 is supported by the arched corrugated plate 3. Since the arched structure itself has good load-bearing capacity, it can disperse the pressure on the culvert. Furthermore, concrete 4 is filled into the interior of the arched corrugated plate 3 through the second grouting hole 14, which enhances the strength of the arched corrugated plate 3. This makes the corrugated pipe culvert body 6 more stably supported, and thus the opening of the corrugated pipe culvert body 6 can be used more stably and durablely.

[0033] In this embodiment, the central axis of the mounting hole 12 and the central axis of the arched corrugated plate 3 are located on the same vertical plane to ensure that the corrugated pipe culvert body 6 is subjected to uniform force in the vertical direction, thereby making the corrugated pipe culvert body 6 more stable and reliablely supported on the arched corrugated plate 3.

[0034] Furthermore, auxiliary support components 5 are provided on both sides below the corrugated pipe culvert body 6 inside the support box 1. One end of the auxiliary support component 5 is connected to the outer wall of the corrugated pipe culvert body 6, and the other end is connected to the bottom plate 15.

[0035] The auxiliary support assembly 5 includes three support rods 51 and a corrugated steel pad 52. The corrugated steel pad 52 is welded to the outer wall of the corrugated pipe culvert body 6. The support rods 51 are arranged at equal intervals along the axial direction of the corrugated pipe culvert body 6. The upper end of the support rod 51 is welded and fixed to the corrugated steel pad 52, and the lower end is welded and fixed to the bottom plate 15.

[0036] As a component that directly contacts the corrugated pipe culvert body 6, the corrugated steel pad 52 can evenly distribute the weight of the corrugated pipe culvert body 6, preventing excessive local pressure from damaging the corrugated pipe culvert body 6. The inclined support rods 51, by virtue of their inclination angle, effectively transmit the force borne by the corrugated steel pad 52 to the bottom of the support box 1. The support rods 51 are arranged at equal intervals along the axial direction, so that the corrugated pipe culvert body 6 is subjected to uniform support force along the axial direction.

[0037] In this embodiment, multiple reinforcing ribs for strengthening the support are uniformly welded on the outer side of the support box 1. A water baffle is provided at the lower end of the support box 1. The water baffle is vertically connected to the front end of the bottom plate 15 of the support box 1 and is buried underground below the bottom plate 15, which can effectively prevent the opening of the corrugated pipe culvert body 6 from being damaged by water erosion.

[0038] The installation process in this embodiment is as follows: In use, an arched corrugated plate 3 is pre-installed at the bottom of the support box 1, and the corrugated pipe culvert body 6 is inserted through the two mounting holes 12 of the support box 1, with the bottom of the corrugated pipe culvert body 6 abutting against the arched corrugated plate 3 to support the corrugated pipe culvert body 6; then, multiple steel meshes 2 are arranged inside the support box 1 to ensure that the ends of the steel meshes 2 are firmly and reliably connected to the support box 1 and the corrugated pipe culvert body 6; finally, concrete 4 is poured into the reinforcing cavity 11 and the arched corrugated plate 3 through the first grouting hole 13 and the second grouting hole 14. When pouring concrete 4, the pouring speed and amount must be controlled to ensure that the concrete 4 can be evenly filled into the reinforcing cavity 11 and the interior of the arched corrugated plate 3.

[0039] Example 2: This embodiment provides a corrugated pipe culvert, including a corrugated pipe culvert body 6. The corrugated pipe culvert body 6 is provided with the opening support structure in Embodiment 1, which makes the opening of the corrugated pipe culvert body 6 more stable and durable, thereby enabling the entire corrugated pipe culvert to work safely.

[0040] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
