Description

Technical Field

[0001] This utility model is a bridge greening railing device, belonging to the field of bridge railings. Background Technology

[0002] Bridge green railings are composite facilities integrating traffic protection and ecological landscaping. They not only provide safety protection for pedestrians and vehicles on both sides of the bridge, but also enhance the bridge's ecological integrity and aesthetics through green planting. Simultaneously, they alleviate driver visual fatigue and improve the local microenvironment, making them widely used in modern municipal bridge construction. In common bridge green railing designs, creating planting spaces by fixing planting boxes to the railing is a fundamental way to achieve "protection + greening." The planting boxes are filled with nutrient-rich soil suitable for plant growth, providing a carrier for shrubs, flowers, vines, and other plants to take root and absorb nutrients, thereby achieving the goals of bridge landscaping and ecological regulation.

[0003] In daily irrigation or natural rainfall scenarios, soil loss due to water discharge can easily lead to muddy water seepage and pollution. From the pollution formation process, when water is manually poured into the planting box, or rainwater naturally flows into it, the soil absorbs some water to meet the plant's growth needs. However, excess water exceeding the soil's water-holding capacity must be drained through the pre-designed drainage holes at the bottom of the planting box to prevent waterlogging and root rot. During this process, soil particles move with the water flow: on the one hand, the nutrient soil in the planting box is mostly loose and breathable mixed soil (containing humus, fine sand, etc.), with weak cohesion between particles. Water flow easily carries surface fine soil particles into the water, forming turbid muddy water; on the other hand, although the drainage holes can drain excess water, the muddy water will flow directly from the drainage holes, dripping or flowing along the outer wall of the planting box. For guardrails, flowing mud and water will form irregular mud stains on the surface, which will turn into dark patches after drying, ruining the original clean appearance of the guardrails. For bridge surfaces (such as bridge deck paving and sidewalk tiles), dripping mud and water will form slippery mud areas on the ground, which will not only increase the safety hazards of pedestrians slipping and vehicles skidding, but also require frequent manual cleaning. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bridge greening railing device to solve the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bridge greening railing device, comprising: Guardrail body; A planting box is installed on one side of the guardrail. The upper and lower ends of the planting box are open. A support plate for supporting the soil is provided in the lower part of the planting box. Multiple drainage holes are opened on one side of the upper surface of the support plate. A sedimentation box is located on the lower side of the planting box. The upper end of the sedimentation box is open and is inserted into the lower end of the planting box. Multiple partitions are evenly installed inside the sedimentation box, which divide the internal space of the sedimentation box into multiple sedimentation chambers. A first overflow outlet is opened at the upper part of the side of the sedimentation box away from the drain outlet, and a second overflow outlet is opened at the upper part of the side of the partition.

[0006] Furthermore, a plurality of first half-threaded screws are evenly installed on the side of the planting box facing the guardrail body, and a plurality of first through holes are evenly opened in the area of ​​the guardrail body covered by the planting box. One end of the first half-threaded screw passes through the first through hole and is threadedly connected to a first nut.

[0007] Furthermore, a plurality of second half-threaded screws are evenly installed on the side of the sedimentation box facing the guardrail body, and a plurality of second through holes are evenly opened in the area of ​​the guardrail body covered by the sedimentation box. One end of the second half-threaded screw passes through the second through hole and is threadedly connected to a second nut.

[0008] Furthermore, a connector frame is installed at the lower part of the planting box, the tray is in contact with the connector frame, the lower end of the connector frame is inserted into the sedimentation box, and the connector frame is in contact with the inner wall of the sedimentation box.

[0009] Furthermore, a base is installed at the bottom of the guardrail, and the base and the guardrail are integrally formed.

[0010] Furthermore, one side of the guardrail body is provided with multiple reserved holes for inserting tie rods through the guardrail body, and the multiple reserved holes are arranged at equal intervals vertically.

[0011] Furthermore, the bottom of the base is recessed downwards to form two grooves, which are arranged symmetrically.

[0012] Furthermore, the side of the planting box facing the guardrail is a first inclined surface that fits against the side of the guardrail, and the side of the sedimentation box facing the guardrail is a second inclined surface that fits against the side of the guardrail.

[0013] The beneficial effects of this utility model are: The sedimentation box under the planting box is divided into multiple sedimentation chambers by a partition, forming a step-by-step sedimentation channel. The muddy water flowing out of the drain first enters the first sedimentation chamber. After the flow rate slows down, most of the fine soil particles are deposited to the bottom under the action of gravity. The remaining small amount of suspended particles enter the next sedimentation chamber with the water through the second overflow of the partition, and settle again. Finally, the clear water after multiple rounds of sedimentation is discharged from the first overflow of the sedimentation box, which avoids muddy water dripping directly, prevents mud stains from forming on the surface of the guardrail, and prevents the soil in the planting box from making the bridge surface wet and muddy. This reduces the safety hazards of pedestrians slipping and vehicles skidding, and reduces the frequency and cost of manual cleaning. Attached Figure Description

Multiple first through holes are evenly opened in the area of ​​the guardrail 1 covered by the planting box 2, so that one end of the first half-threaded screw 4 passes through the first through hole and is threadedly connected to the first nut 41, thereby installing the planting box 2 on one side of the guardrail 1. At this time, the first inclined surface on the planting box 2 is in contact with the side of the guardrail 1, increasing the contact area between the planting box 2 and the guardrail 1. The sedimentation box 3 is set on the lower side of the planting box 2. Multiple second half-threaded screws 5 are evenly installed on the side of the sedimentation box 3 facing the guardrail 1. Multiple second through holes are evenly opened in the area of ​​the guardrail 1 covered by the sedimentation box 3, so that one end of the second half-threaded screw 5 passes through the second through hole and is threadedly connected to the second nut 51, completing the assembly of the sedimentation box 3 and the guardrail 1. At this time, the second inclined surface on the sedimentation box 3 is in contact with the side of the guardrail 1, increasing the contact area between the sedimentation box 3 and the guardrail 1.

[0018] See Figures 1-4 The planting box 2 has an open top and bottom. A support plate 21 for supporting the soil is located in the lower part of the planting box 2. Multiple drainage holes 22 are located on one side of the upper surface of the support plate 21. A connecting frame 23 is installed in the lower part of the planting box 2, with the support plate 21 in contact with the connecting frame 23. The lower end of the connecting frame 23 is inserted into the sedimentation box 3, contacting the inner wall of the sedimentation box 3.
