Description

Technical Field

[0001] This utility model relates to the fields of traffic engineering and municipal engineering technology, specifically a closed box culvert with reinforcing ribs. Background Technology

[0002] In transportation and municipal engineering, box culverts are an important underground structure, often used to construct culverts, tunnels, underground passages, and underground pipelines to achieve functions such as drainage, passage, or pipeline laying. Corrugated sheets have become a commonly used material for making box culverts due to their advantages such as strong resistance to deformation, quick and convenient installation, time-saving construction, low cost, and environmental friendliness.

[0003] To improve cross-sectional utilization, existing corrugated plate box culverts mostly adopt an approximately rectangular structural cross-section. However, the load-bearing capacity of an approximately rectangular structure is limited, making it difficult to meet the needs of complex geological conditions or high-load scenarios. Furthermore, the bottom slab and arch slab of the box culvert are usually connected by arch foot connectors, which are made of bent flat steel plates. These connectors create cavities between the culvert and the corrugated plate, which, if not properly handled, can easily affect structural stability. Additionally, the corrugated section of the bottom slab connects to the outside, potentially allowing debris to enter or compromising structural strength.

[0004] Therefore, there is an urgent need for a closed box culvert structure that can enhance structural load-bearing capacity and optimize connection stability. Utility Model Content

[0005] The purpose of this invention is to provide a closed box culvert with reinforcing ribs to improve the load-bearing capacity and structural stability of the box culvert.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A closed box culvert with reinforcing ribs includes a corrugated steel arch plate, a corrugated steel bottom plate, and a corrugated steel baffle plate, which together form a closed box culvert frame. The corrugated steel arch plate is located at the top of the box culvert and has an arched structure, while the corrugated steel bottom plate is located at the bottom of the box culvert. The corrugated steel arch plate and the corrugated steel bottom plate are connected by arch foot connectors to form an approximately rectangular cross-sectional structure. The corrugated steel arch plate has reinforcing ribs spaced apart in the corrugated grooves, and the reinforcing ribs are connected to the corrugated steel arch plate through connecting plates.

[0007] As a further improvement to the above solution, the reinforcing rib is an H-beam reinforcing rib, which is fixed in the middle of the connecting plate. The connecting plate is fixedly connected to two adjacent crests of the corrugated steel arch plate by bolts, and the lower ends of the H-beam reinforcing rib are connected to the two side walls of the corrugated groove of the corrugated steel arch plate.

[0008] As a further improvement to the above solution, the reinforcing rib is a round tube reinforcing rib, which is fixedly connected in the corrugated groove of the corrugated steel arch plate, and the two ends of the connecting plate are fixedly connected to two adjacent crests of the corrugated steel arch plate by bolts. The middle part of the connecting plate is arc-shaped and fits and is fixed to the top of the round tube reinforcing rib.

[0009] As a further improvement to the above solution, the arch foot connector is made of flat steel plate by bending, and the cavity formed by its connection with the corrugated steel arch plate and the corrugated steel bottom plate is filled with concrete.

[0010] As a further improvement to the above solution, one side of the corrugated steel baffle is corrugated, the corrugated steel baffle is vertically arranged inside the corrugated steel base plate, and the corrugated side is sealed to the inner corrugated surface of the corrugated steel base plate by a sealing strip; the corrugated part of the corrugated steel base plate located outside the corrugated steel baffle is filled with concrete.

[0011] As a further improvement to the above solution, a pad is also provided in the corrugated groove of the corrugated steel arch plate with reinforcing ribs. The pad fits against the outer surface of the corrugated steel arch plate and extends to the two adjacent crests of the corrugated steel arch plate; the two ends of the connecting plate are respectively fixed to the pad.

[0012] As a further improvement to the above solution, the cross-section of the arch foot connector is L-shaped, and one side of the arch foot connector is attached to the inner side of the corrugated steel base plate and is provided with an inner flange. The inner flange is connected to the corrugated steel baffle by bolts, and the other side of the arch foot connector extends to the outer side of the corrugated steel arch plate and is connected to the corrugated steel arch plate by bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model provides a closed box culvert with reinforcing ribs. By setting H-shaped steel reinforcing ribs or round pipe reinforcing ribs and using connecting plates to connect the reinforcing ribs to the corrugated pipe body, the overall load-bearing capacity of the box culvert with an approximately rectangular cross section is effectively improved, enabling it to adapt to more complex geological conditions and higher load requirements.

[0014] 2. The cavity formed by the connection between the arch foot connector and the corrugated plate in this utility model is filled with concrete, which avoids the adverse effects of the cavity on the structural stability. At the same time, the setting of the corrugated steel baffle and the rubber sealing strip, together with the concrete filling at the outer corrugation, solves the problem of the connection between the bottom plate corrugation and the outside, further enhancing the structural sealing and stability of the box culvert.

[0015] 3. This utility model continues the advantages of corrugated plates, such as strong resistance to deformation, quick installation, low cost, and environmental friendliness. While enhancing structural performance, it does not increase construction difficulty and cost excessively, making it highly applicable. Attached Figure Description
