Description

Technical Field

[0001] This utility model relates to the field of corrugated steel technology, specifically to a reinforcing structure for corrugated pipes and a corrugated steel culvert. Background Technology

[0002] Corrugated steel structures are widely used in various fields due to their excellent resistance to deformation and efficient installation. When corrugated pipes are used as the main structure of culverts, their design needs to ensure that the culvert has excellent load-bearing capacity, strength, stiffness, and other mechanical properties to ensure that the culvert remains stable and does not easily deform during use, thereby meeting the requirements of safety and durability.

[0003] However, despite the many advantages of corrugated pipe culverts, their structural performance is still limited in certain extreme or special environments, resulting in weaker load-bearing capacity, strength, and stiffness, making them unable to fully adapt to complex usage conditions.

[0004] Therefore, there is an urgent need for a corrugated pipe reinforcement structure and culvert that can enhance the load-bearing capacity, strength and stiffness of corrugated pipe culverts. Summary of the Invention

[0005] The purpose of this invention is to provide a reinforced structure for corrugated pipes and a corrugated steel culvert, so as to at least solve the problems of weak load-bearing capacity, strength and stiffness of current corrugated pipe culverts.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A reinforcing structure for corrugated pipes includes a corrugated steel pad, multiple annular vertical plates, multiple reinforcing plates, annular connecting parts, and concrete. The corrugated steel pad is circumferentially disposed around the outer periphery of the corrugated pipe, and the annular vertical plate is circumferentially and vertically disposed on the corrugated steel pad and arranged at intervals along the axial direction of the corrugated pipe. A filling gap is formed between adjacent annular vertical plates, and the reinforcing plates are all disposed in the filling gap and are respectively circumferentially connected between adjacent annular vertical plates. The annular connecting piece is circumferentially disposed at the upper end of the two outer annular vertical plates. A filling cavity is formed between the annular connecting piece and the reinforcing plate. A steel mesh is provided in the filling cavity. Multiple grouting holes are opened at the top of the annular connecting piece. The concrete is poured into the filling spacing and the filling cavity from the grouting holes.

[0007] Furthermore, the annular vertical plate includes two opposing semi-annular plates, which are connected by end flanges.

[0008] Furthermore, the vertical cross-section of the annular connecting member is inverted U-shaped, including an annular top plate and annular side plates disposed on both sides of the annular top plate. The annular side plates extend radially inward along the annular top plate, and the lower ends of the annular side plates are respectively connected to the two outer annular vertical plates.

[0009] Furthermore, each of the two outer annular vertical plates is provided with an outwardly extending first annular connecting plate at its upper end.

[0010] Furthermore, each of the annular side plates is provided with a second annular connecting plate extending outward and docking with the first annular connecting plate at its lower end.

[0011] Furthermore, the first annular connecting plate and the second annular connecting plate are connected by fasteners.

[0012] Furthermore, the filling cavity is provided with a plurality of connecting steel bars, one end of which is vertically connected to the annular top plate, and the other end extends through the steel mesh into the filling spacing.

[0013] Furthermore, a flow gap is provided between the lower end face of the reinforcing plate and the corrugated steel pad.

[0014] Furthermore, the annular vertical plate is disposed in the trough of the corrugated steel pad.

[0015] A corrugated steel culvert includes a corrugated pipe, wherein a plurality of the above-mentioned corrugated pipe reinforcement structures are arranged at axial intervals along the outer periphery of the corrugated pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a reinforced structure for corrugated pipes and a corrugated steel culvert. The corrugated pipe is provided with a corrugated steel pad, multiple annular vertical plates, multiple reinforcing plates and annular connecting parts. Concrete is injected into the structure through grouting holes on the annular connecting parts, making the entire structure a solid whole, thereby enhancing the load-bearing capacity, strength and stiffness of the corrugated pipe itself. Whether it is subjected to vertical pressure, such as the weight of the overlying soil, or lateral pressure, such as the compression of the surrounding soil, it can exhibit excellent performance to meet environmental requirements.

[0017] 2. This utility model provides multiple reinforcing structures spaced along the axial direction on the corrugated pipe, thereby improving the mechanical properties of the culvert's load-bearing capacity, strength, and stiffness at multiple locations along the axial direction. This effectively prevents the corrugated pipe from deforming or cracking due to long-term pressure, greatly extending its service life, reducing maintenance costs, and improving the overall safety and reliability of the culvert, thus ensuring a more stable and safer use of the culvert.

[0024] Example 1: This embodiment provides a reinforcing structure for corrugated pipes, including a corrugated steel pad 1, three annular vertical plates 2, multiple reinforcing plates 3, annular connecting parts 4, and concrete 5.

[0025] Specifically, a corrugated steel pad 1 is arranged around the outer periphery of the corrugated pipe 6 to prevent stress concentration at the connection point between the corrugated pipe 6 and the annular vertical plate 2.

[0026] The annular vertical plate 2 is welded vertically to the corrugated steel pad 1 and arranged parallel to each other at intervals along the axial direction of the corrugated pipe 6, which effectively increases the axial stability of the overall structure. In this embodiment, the annular vertical plate 2 is set in the trough of the corrugated steel pad 1, thereby improving the tightness and strength of the connection between the annular vertical plate 2 and the corrugated steel pad 1, and a filling gap 21 is formed between adjacent annular vertical plates 2.

[0027] The annular vertical plate 2 includes two opposing semi-annular plates 23. Both ends of the semi-annular plates 23 are welded with end flanges, and corresponding through holes are opened on the end flanges. After the two end flanges are connected, they are fixedly connected by bolts and nuts, so that the two semi-annular plates 23 are connected into one body to form a closed annular vertical stiffening rib, which is convenient and quick to install.

[0028] Specifically, the reinforcing plates 3 are arranged circumferentially in the filling gap 21, and the reinforcing plates 3 are welded and fixed between adjacent annular vertical plates 2 as stiffening ribs. The top of the reinforcing plates 3 is flush with the upper surface of the annular vertical plates 2, which greatly improves the strength of the overall structure in this area and prevents local deformation. There is a gap between the lower surface of the reinforcing plates 3 and the crest of the corrugated steel pad 1, so that a flow gap 31 is formed between the lower surface of the reinforcing plates 3 and the corrugated steel pad 1. This ensures that the reinforcing plates 3 do not obstruct the connectivity of the filling gap 21 between adjacent annular vertical plates 2, thus facilitating the pouring of concrete 5 to fill the entire filling gap 21.

[0029] In this embodiment, the annular connecting piece 4 is circumferentially disposed at the upper end of the two outer annular vertical plates 2 to close the filling gap 21, and a filling cavity 41 is formed between the annular connecting piece 4 and the reinforcing plate 3. A steel mesh 42 is disposed in the filling cavity 41. The steel mesh 42 is circumferentially arranged and connected to the connecting steel bar 48, thereby connecting with the annular top plate 44 as a whole, thereby further enhancing the overall strength of the structure.

[0030] The vertical cross-section of the annular connecting member 4 is inverted U-shaped. When subjected to external force, it can evenly distribute the force to each component, thereby improving the load-bearing capacity of the entire structure. The annular connecting member 4 includes an annular top plate 44 and annular side plates 45 integrally disposed on both sides of the annular top plate 44. The annular side plates 45 extend radially inward along the annular top plate 44, and the lower ends of the annular side plates 45 are respectively connected to the two outer annular vertical plates 2. The annular top plate 44 and the two annular side plates 45 form a filling cavity 41, so that the concrete 5 can be effectively confined in the filling cavity 41 to avoid leakage.

[0031] In this embodiment, the upper ends of the two outer annular vertical plates 2 are integrally provided with a first annular connecting plate 22 extending vertically outward, and the first annular connecting plate 22 is provided with a plurality of first connecting holes.

[0032] Each annular side plate 45 has a second annular connecting plate 46 extending vertically outward and docking with the first annular connecting plate 22 at its lower end. The second annular connecting plate 46 has multiple second connecting holes.

[0033] The first annular connecting plate 22 and the second annular connecting plate 46 are fixedly connected by fasteners 47 that pass through the first connecting hole and the second connecting hole in sequence. When installing the annular docking piece 4, the two second annular connecting plates 46 are docked on the two first annular connecting plates 22, and the first connecting hole and the second connecting hole are precisely aligned to ensure that the fasteners 47 can pass through smoothly. In this embodiment, the fasteners 47 are high-strength bolts, which can provide sufficient connection strength to ensure the stability of the connection between the annular vertical plate 2 and the annular docking piece 4. After assembly, in order to prevent the fasteners 47 from loosening, anti-loosening nuts are added to the bolts. At the same time, sealant is applied between the mating surfaces of the first annular connecting plate 22 and the second annular connecting plate 46, which can effectively prevent external moisture or impurities from entering the connection part, thereby improving the service life and reliability of the entire structure.

[0034] Specifically, multiple connecting steel bars 48 are provided in the filling cavity 41, which can further improve the load-bearing capacity and strength of the entire structure after the concrete 5 is poured. One end of the connecting steel bar 48 is vertically welded to the lower end face of the annular top plate 44, and the other end extends through the steel mesh 42 into the filling spacing 21. The steel mesh 42 is welded to the connecting steel bar 48. At the same time, the connecting steel bar 48 provides a stable support point for the steel mesh 42, making the connection between the steel mesh 42 and the annular top plate 44 more solid. When subjected to external force, the force can be transmitted more evenly between the annular top plate 44, the connecting steel bar 48 and the steel mesh 42, thereby avoiding excessive local stress that could lead to structural damage.

[0035] In this embodiment, the other end of the connecting steel bar 48 extends into the filling gap 21 to increase the contact area between the connecting steel bar 48 and the concrete 50, thereby playing a more stable role. In other embodiments, the other end of the connecting steel bar 48 can also extend into the filling gap 21 and connect with the corrugated steel pad 1, thereby further improving the overall integrity of the entire structure.

[0036] The annular top plate 44 of the annular connector 4 has multiple grouting holes 43, which are used to pour concrete 5 into the filling spacing 21 and filling cavity 41 through the grouting holes 43, making the whole structure a solid whole, thereby enhancing the load-bearing capacity, strength and rigidity of the corrugated pipe 6 to meet environmental requirements. In this embodiment, the multiple grouting holes 43 are divided into two groups, and the two groups of grouting holes 43 are located on both sides of the upper end flange, and the multiple grouting holes 43 in the same group correspond one-to-one with the multiple filling spacings 21.

[0037] Example 2: This embodiment provides a corrugated steel culvert, including a corrugated pipe 6. The corrugated pipe 6 is provided with multiple reinforcing structures as described in Embodiment 1 at intervals on its outer periphery. This improves the mechanical properties of the culvert in terms of load-bearing capacity, strength, and stiffness at multiple locations along the axial direction, effectively preventing the corrugated pipe 6 from deforming or cracking due to long-term pressure. This greatly extends the service life of the corrugated pipe 6, reduces maintenance costs, and also improves the overall safety and reliability of the culvert, thereby ensuring a more stable and safer use of the culvert.

[0038] 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.
