Technical Field
[0001] The utility model relates to the field of engineering construction, in particular to a simple box culvert flood control gate structure. Background Art
[0002] During the flood season, it is crucial to take a series of flood prevention measures to protect important facilities (subway stations) downstream. Blocking floodwaters to upstream flood storage areas is a common flood prevention strategy, the main purpose of which is to reduce flood pressure in downstream areas and ensure the safety of people's lives and property.
[0003] The flood storage area is located in the upper reaches of the river and has a large water storage capacity. When a flood comes, the flood is blocked in the flood storage area by blocking the discharge channel, thereby slowing down the peak flow and reducing the flood level in the downstream area (subway station). This can buy more response time for the downstream area and reduce the impact of the flood on infrastructure such as the downstream subway station.
[0004] At present, there is no control gate at the upstream entrance of the 1# and 2# box culverts in the Suyang area flood detention area on National Highway 316. When encountering excessive floods, it is impossible to control the amount of flood water entering the flood detention area before the subway, and it is impossible to block the flood water to the upstream flood detention area.

[0021] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.
[0022] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0023] like Figures 1 to 6 As shown, a simple box culvert flood control gate structure comprises a culvert 2 passing through the bottom of a road 1 (i.e., National Highway 316), and a gate device is provided at the culvert opening on one side of the road; the gate device comprises a reinforced concrete base 3 and reinforced concrete columns 4 erected above both ends of the reinforced concrete base, a vertical guide groove 5 is provided on the middle side of the reinforced concrete column facing downward, and a gate 6 that can slide up and down relative to the vertical guide groove is provided between the reinforced concrete columns on both sides; slopes 7 are provided on both sides of the road, and a platform 8 located above the slope is set between the reinforced concrete columns and the road, and a winch 9 is provided on the platform, and the traction end of the wire rope on the winch is connected to the upper side of the gate.
[0024] In this embodiment, the reinforced concrete base 3 and the reinforced concrete column 4 are close to the opening of the culvert 2 , and the upper surface of the reinforced concrete base 3 is flush with the bottom surface of the culvert 2 .
[0025] The utility model combines the actual situation of the project and considers that the flow rate during the flood season is far greater than the existing drainage capacity, and builds a control gate at the upstream entrance of the culvert. When encountering excessive floods, the flood volume entering the flood detention area before the subway is controlled, and the flood is blocked in the upstream flood detention area, reducing the flooding elevation of the area near the subway station, ensuring the safety of the subway during the flood season. In addition, the gate structure can be made of common steel materials on the construction site, with a simple structure and convenient production, which can ensure the safety of flood season and save project investment.
[0026] The gate opening and closing work is completed by a 25t winch installed on the platform. The winch is a mechanical device used to lift, pull or drag heavy objects. Its strong pulling force can ensure the gate to open and close smoothly. The operator controls the operation of the winch to make the gate rise or fall as needed. This method not only improves work efficiency, but also reduces the difficulty and risk of manual operation.
[0027] In this embodiment, a bracket 10 is provided above the reinforced concrete column 4, and a pulley 11 located just above the gate is installed on the bracket, and the steel wire rope passes around the pulley.
[0028] In this embodiment, the platform is composed of a plurality of I-beams arranged at intervals in the transverse direction and a steel plate laid on the upper side of the I-beams.
[0029] In this embodiment, the gate includes a main frame formed by connecting a plurality of I-beams and angle steels, and a steel plate is welded to one side of the main frame.
[0030] In this embodiment, a trash rack 12 is provided at the water inlet side of the gate device. The trash rack is tilted and has an angle of 60° with the horizontal plane.
[0031] In this embodiment, a sand and gravel cushion layer is laid at the bottom of the reinforced concrete base.
[0032] Unless otherwise stated, any technical solution disclosed in the above utility model, if it discloses a numerical range, then the disclosed numerical range is a preferred numerical range. Any technician in the field should understand that the preferred numerical range is only a numerical value with a more obvious technical effect or representative value among many feasible numerical values. Since there are too many numerical values to be exhaustive, the utility model discloses only some numerical values to illustrate the technical solution of the utility model, and the numerical values listed above should not constitute a limitation on the scope of protection of the utility model.
[0033] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except when it is obviously impossible to use an one-piece molding process).
[0034] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.
[0035] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.
