Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe culvert technology, specifically to a reinforced structure for a double-layer steel-concrete corrugated pipe culvert. Background Technology

[0002] Corrugated pipe culverts are widely used in the construction of transportation infrastructure such as highways and railways due to their excellent mechanical properties and ease of construction. However, existing corrugated pipe culvert structures mostly adopt single-layer corrugated plates or simple double-layer structures, which have many shortcomings in practical engineering applications. On the one hand, due to the lack of effective load-distributing components, under external forces such as soil pressure and vehicle dynamic loads, the load is difficult to distribute evenly, and stress concentration is easily formed at the crests and troughs of the corrugated plates, leading to fatigue cracks or even local failure of the structure. On the other hand, the cooperative working capacity between the inner and outer corrugated plates is limited, and there is a lack of effective supporting components. Under large external loads or adverse geological conditions, relative displacement and excessive deformation are prone to occur, leading to overall instability of the culvert. Utility Model Content

A support portion is provided between the inner corrugated plate and the outer corrugated plate. The support portion includes a supporting corrugated plate and a supporting arc plate. The upper end of the supporting corrugated plate is disposed on the outer corrugated plate, and the lower end of the supporting corrugated plate is connected to the upper surface of the supporting arc plate. The lower surface of the supporting arc plate abuts against the inner corrugated plate. The support portion is used to support the inner corrugated plate and the outer corrugated plate, thereby forming a gap between the inner corrugated plate and the outer corrugated plate.

[0005] According to another aspect, at least one embodiment of the present invention also provides a reinforced structure for a double-layer steel-concrete corrugated pipe culvert, which further includes T-shaped steel.

The sidewall of the connecting flange is connected to one end of the inner corrugated plate and the outer corrugated plate that are close to each other. The two connecting flanges are a group and are located at opposite ends of the inner corrugated plate. The T-shaped steel and the connecting flange are alternately distributed at the ends of the inner corrugated plate to form an enclosing space between the inner corrugated plate and the outer corrugated plate.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0023] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0024] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] like Figures 1-4 As shown, this illustrates a reinforced structure for a double-layered steel-concrete corrugated pipe culvert according to one embodiment of the present invention. In this example, the length extension direction of the corrugations is the length direction of the inner corrugated plate 100 and the outer corrugated plate 200.

[0029] In this embodiment, the inner corrugated plate 100 and the outer corrugated plate 200 are arranged in parallel and spaced apart, together forming the internal and external stress-bearing system of the culvert. They are supported by a support portion 300, wherein the supporting corrugated plate 310 of the support portion 300 is welded, with its upper end firmly fixed to the inner side of the outer corrugated plate 200, and its lower end butt-connected to the upper surface of the supporting arc plate 320. The arc design of the supporting arc plate 320 matches the stress requirements of the inner corrugated plate 100, and its lower surface tightly abuts against the inner corrugated plate 100. By evenly distributing the load, a stable and reasonable spacing is ensured between the inner corrugated plate 100 and the outer corrugated plate 200, effectively improving the overall structure's resistance to compression and deformation.

[0030] To further enhance the structure's sealing and integrity, T-shaped steel 400 is incorporated into the structure. In this example, the T-shaped steel 400 is a T-shaped steel, with its two ends respectively installed on the inner corrugated plate 100 and the outer corrugated plate 200, symmetrically distributed in pairs at opposite ends of the inner corrugated plate 100. The pre-machined outward-flared flanges 210 at the ends of the inner corrugated plate 100 and the outer corrugated plate 200 are securely connected to the T-shaped steel 400 via bolts. This not only facilitates rapid on-site assembly but also forms a reliable sealing structure at the connection point, preventing external water and soil infiltration. Simultaneously, the sidewalls of the connecting flanges 500 are connected to the adjacent ends of the inner corrugated plate 100 and the outer corrugated plate 200, also in pairs at opposite ends of the inner corrugated plate 100. The T-shaped steel 400 and the connecting flanges 500 are alternately distributed at the ends of the inner corrugated plate 100, forming a closed enclosing space 600 between the inner corrugated plate 100 and the outer corrugated plate 200. Within this space, reinforcing ribs 700 are arranged. These reinforcing ribs 700 work together with the inner corrugated plate 100, the outer corrugated plate 200, the T-shaped steel 400 and the connecting flange 500 to further enhance the load-bearing strength of the structure under complex load conditions.

[0031] From a structural composition and splicing perspective, the inner corrugated plate 100, outer corrugated plate 200, support 300, a set of T-shaped steel 400, and a set of connecting flanges 500 together form a standardized splicing unit 10. Multiple splicing units 10 can be connected sequentially according to the actual requirements of the culvert's length and diameter. A set of connecting flanges 500 located at both ends of the inner corrugated plate 100 parallel to the corrugation length direction are tightly fixed with bolts, ultimately forming an annular space 800, constructing a complete culvert structure. Furthermore, the corrugated cross-section of the inner corrugated plate 100 adopts a sequentially connected trapezoidal or wave-shaped design. This special shape effectively disperses stress and avoids localized stress concentration. The trapezoidal corrugations allow for a more stable installation of the reinforcing steel frame, and their geometric contour provides a stable and close-fitting mounting surface for the reinforcing steel frame. The support 300 is installed at both ends at the troughs of the inner corrugated plate 100 and the outer corrugated plate 200, cooperating with the corrugated structure to fully utilize the structural mechanical properties. The inner corrugated plate 100 and the outer corrugated plate 200 extend along the length of the corrugations in an arc shape. This design enables them to better adapt to the structural stress requirements of culverts under complex environments such as foundation settlement and vehicle dynamic loads, thereby improving the overall stability and load-bearing capacity of the structure. It is suitable for culvert construction in transportation projects such as highways and railways, and its advantages are particularly prominent under complex geological conditions such as soft soil foundations and high embankment sections.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
