Technical Field

[0001] This utility model belongs to the field of corrugated steel technology, and more specifically, it relates to a corrugated steel reinforced structure and a corrugated steel culvert. Background Technology

[0002] Corrugated steel structures are widely used in various fields due to their strong resistance to deformation and quick installation. When corrugated pipes are used as the main structure of culverts, the culverts need to have good load-bearing capacity, strength, and stiffness to ensure that they are not easily deformed and can be used safely and stably. Although culverts made of corrugated pipes have good characteristics, their structural performance may still not meet the requirements in special environments. Utility Model Content

[0003] The purpose of this utility model is to provide a corrugated steel reinforced structure and a corrugated steel culvert to solve the technical problem that the mechanical properties of corrugated pipe culverts in the prior art, such as load-bearing capacity, strength and stiffness, cannot meet the requirements.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a corrugated steel reinforced structure, comprising:

[0005] Multiple arc-shaped corrugated plates are used to be installed on the outer surface of the corrugated steel culvert and are arranged at intervals along the circumference of the corrugated steel culvert; the arc-shaped corrugated plates are adapted to be installed on the outer surface of the corrugated steel culvert.

[0006] The longitudinal stiffeners are in a ring shape; there are multiple longitudinal stiffeners, which are arranged in parallel at intervals along the axial direction of the arc-shaped corrugated plates; the multiple arc-shaped corrugated plates are located inside the longitudinal stiffeners, and the inner wall of the longitudinal stiffeners is fixedly connected to the outer wall of the multiple arc-shaped corrugated plates.

[0007] Multiple transverse stiffener groups are installed between two adjacent longitudinal stiffeners, with both ends of each transverse stiffener fixedly connected to the two longitudinal stiffeners. Multiple transverse stiffeners in the same transverse stiffener group are arranged at intervals along the circumference of the corrugated steel culvert.

[0008] In one possible implementation, the inner walls of the plurality of longitudinal stiffeners are installed in the troughs of the arc-shaped corrugated plate.

[0009] In one possible implementation, two adjacent longitudinal stiffeners are located in two adjacent troughs of the arc-shaped corrugated plate.

[0010] In one possible implementation, the longitudinal stiffener includes a plurality of arc-shaped plates that are butted together to form a ring structure, and the ends of the plurality of arc-shaped plates arranged in parallel on the plurality of longitudinal stiffeners are provided with end flanges for fixing two arc-shaped plates arranged adjacent to each other in the circumferential direction.

[0011] In one possible implementation, the end flange is located between two adjacent arc-shaped corrugated plates, and the end flange is provided with a corrugated section adapted to the outer surface of the corrugated steel culvert.

[0012] In one possible implementation, the longitudinal stiffener includes two of the arc-shaped plates; the two end flanges are butted together and fixedly connected by bolts, for clamping the multiple longitudinal stiffeners onto the corrugated steel culvert.

[0013] In one possible implementation, the longitudinal stiffener is an annular plate, and the transverse stiffener is a rectangular plate.

[0014] The beneficial effects of the corrugated steel reinforcement structure provided by this utility model are as follows: Compared with the prior art, the corrugated steel reinforcement structure of this utility model has multiple arc-shaped corrugated plates arranged on the outer surface of the corrugated steel culvert and along the circumference of the corrugated steel culvert; and the waveform of the arc-shaped corrugated plates is consistent with the waveform of the corrugated steel culvert, so that the entire corrugated steel reinforcement structure is installed together. Multiple longitudinal stiffeners are then arranged in parallel and spaced intervals and fitted onto the corrugated steel culvert, with the arc-shaped corrugated plate positioned between the longitudinal stiffeners and the culvert. The inner walls of the longitudinal stiffeners are fixedly connected to the outer walls of the arc-shaped corrugated plate. Multiple transverse stiffener groups are then installed between adjacent longitudinal stiffeners, with the transverse stiffeners in the same group spaced circumferentially along the longitudinal stiffeners and fixedly connected to adjacent longitudinal stiffeners. In this way, the arc-shaped corrugated plate increases the load-bearing area of ​​the corrugated steel reinforcement structure and the corrugated steel culvert, resulting in more uniform stress distribution. Multiple longitudinal and transverse stiffeners provide circumferential strength support for the corrugated steel culvert, forming a robust outer structure. This improves the load-bearing capacity, strength, and stiffness of the corrugated steel culvert, effectively reducing its deformation and meeting the requirements of the operating environment.

[0015] Another objective of this utility model is to provide a corrugated steel culvert, including any of the corrugated steel reinforcement structures described above.

[0016] In one possible implementation, the number of corrugated steel reinforcement structures is multiple, and they are arranged at intervals along the axial direction of the corrugated steel culvert.

[0017] This utility model provides a corrugated steel culvert. Due to the use of corrugated steel reinforcement structure, multiple longitudinal and transverse reinforcing ribs provide circumferential strength support for the corrugated steel culvert and form a robust outer structure, which improves the mechanical properties of the corrugated steel culvert's load-bearing capacity, strength, and stiffness, effectively reduces the deformation of the corrugated steel culvert, and meets the requirements of the usage environment.

The arc-shaped corrugated plates 11 are fitted to the outer surface of the corrugated steel culvert 2. The longitudinal stiffeners 12 are annular structures. Multiple longitudinal stiffeners 12 are arranged parallel to each other axially along the arc-shaped corrugated plates 11. Multiple arc-shaped corrugated plates 11 are located within the longitudinal stiffeners 12, and the inner wall of the longitudinal stiffeners 12 is fixedly connected to the outer wall of the multiple arc-shaped corrugated plates 11. Multiple transverse stiffener groups 13 are installed between two adjacent longitudinal stiffeners 12, and both ends of the transverse stiffeners 131 are fixedly connected to the two longitudinal stiffeners 12. Multiple transverse stiffeners 131 in the same transverse stiffener group 13 are spaced apart circumferentially along the corrugated steel culvert 2.

[0033] Compared with the prior art, the corrugated steel reinforcement structure 1 provided by this utility model has multiple arc-shaped corrugated plates 11 arranged on the outer surface of the corrugated steel culvert 2 and along the circumference of the corrugated steel culvert 2; and the waveform of the arc-shaped corrugated plates 11 is consistent with the waveform of the corrugated steel culvert 2, so that the entire corrugated steel reinforcement structure 1 is installed together. Then, multiple longitudinal reinforcing ribs 12 are arranged in parallel and spaced apart and fitted onto the corrugated steel culvert 2, with the arc-shaped corrugated plate 11 located between the longitudinal reinforcing ribs 12 and the corrugated steel culvert 2.
