Description

Technical Field

[0001] This utility model relates to the field of bridge engineering and urban greening technology, and in particular includes a modular bridge railing greening planting trough device. Background Technology

[0002] Traditional methods of planting greenery in the median strip of bridges involve directly covering the guardrails with soil. This method has many drawbacks. Plant roots are in direct contact with the guardrails, limiting the space for mechanical operations and increasing the difficulty and cost of plant maintenance, replacement, and soil changes. Furthermore, frequent lane closures for construction severely disrupt traffic on the bridge. Guardrails are designed for a 15-year lifespan, and soil corrosion shortens their lifespan. Future reinforcement or repairs will inevitably destroy existing greenery and waste large amounts of plants and planting soil, resulting in significant resource waste and environmental pollution. Communication and lighting cables are buried within the guardrails, making maintenance difficult. Overall, the traditional method is costly to maintain and has poor economic efficiency, requiring optimization and improvement.

[0003] Therefore, there is an urgent need for a bridge railing greening and planting device that can improve construction and maintenance efficiency, extend facility life, reduce traffic control, significantly reduce the full-cycle maintenance cost during bridge operation, and has outstanding economic benefits. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a modular bridge railing greening planting trough device.

[0005] This modular bridge railing greening planting trough device includes: modular planting troughs, a main irrigation pipe, and T-shaped irrigation pipes; the bridge central median railing structure includes railings, a railing base layer, and bridge deck paving; the railing base layer and bridge deck paving are installed on the main beam of the bridge; the railings are installed on the railing base layer, and several modular planting troughs are spaced apart along the bridge direction between the railings; the upper sidewall of the modular planting trough is attached to the sidewall of the railing, and a gap is left between the lower sidewall of the modular planting trough and the sidewall of the railing, with the main irrigation pipe installed in the gap; the T-shaped irrigation pipes are located at the intervals of the modular planting troughs and are vertically connected to the main irrigation pipe; the two sides of the railing base layer are the bridge deck paving, and a gap is left between the bottom of the modular planting trough and the railing base layer, with the bottom of the modular planting trough higher than the bridge deck paving, and drainage holes are provided at the bottom of the modular planting trough.

[0006] Preferably, the top of the modular planting trough extends outward to form a flange structure, and the bottom of the flange structure fits into the top of the guardrail; the upper sidewall of the modular planting trough is provided with a lifting hole, which is located in the interval between the modular planting troughs.

[0007] Preferably, the modular planting trough is divided into an upper modular planting trough and a lower modular planting trough, with the bottom of the upper modular planting trough being wider than the top of the lower modular planting trough.

[0008] Preferably, the modular planting trough is filled from bottom to top with a pebble drainage layer, a fine sand filter layer, and planting soil. The pebble drainage layer and the fine sand filter layer are filled in the lower modular planting trough, and the planting soil is filled in the upper modular planting trough. The height of the planting soil is lower than the height of the hoisting hole, and a permeable geotextile is laid at the bottom of the pebble drainage layer.

[0009] Preferably, the T-shaped irrigation pipe is divided into an upper T-shaped irrigation pipe and a lower T-shaped irrigation pipe, which are connected by a rotary joint; the bottom of the lower T-shaped irrigation pipe is connected to the main irrigation pipe; the bottom of the upper T-shaped irrigation pipe is connected to the rotary joint, and the top of the upper T-shaped irrigation pipe is divided into irrigation branch pipes, which extend into the modular planting trough.

[0010] As a preferred option, a pre-embedded bracket is embedded in the bottom side wall of the guardrail. The pre-embedded bracket is located in the gap between the lower side wall of the modular planting trough and the side wall of the guardrail. The pre-embedded bracket supports municipal pipelines and irrigation water mains.

[0011] As a preferred option, the bottom of the drainage hole in the planting trough is higher than the bridge deck pavement, and there is a gap between the bottom of the pre-embedded support and the bottom layer of the guardrail. Drainage pipes run through the inside and outside of the guardrail.

[0012] The beneficial effects of this utility model are:

[0013] 1) This utility model combines modular planting troughs with the central divider railing of a bridge. The modular planting troughs isolate the greenery from the railing structure, preventing the planting soil from directly contacting the railing and preventing moisture and acid / alkali substances in the soil from corroding the railing. This reduces cracking, rusting, and damage caused by erosion, thereby extending the service life of the railing, reducing maintenance costs, and improving its safety and durability. At the same time, the pipelines are placed on the support between the planting troughs and the railing. The modular planting troughs and the central divider railing of the bridge serve as a rigid protective layer, resisting external impacts, rainwater erosion, and daily wear, significantly improving the operational safety and service life of the pipelines. The modular planting troughs are secured between the central divider railings of the bridge through a flange structure. With the lifting holes of the modular planting troughs, when inspecting the pipelines, only the corresponding modular planting trough needs to be lifted for quick inspection, improving maintenance efficiency and convenience.

[0014] 2) The modular planting trough of this utility model is provided with a permeable geotextile and a drainage hole at the bottom of the planting trough. The drainage hole at the bottom of the planting trough is higher than the bridge surface. The permeable geotextile allows water in the modular planting trough to quickly pass through the drainage hole at the bottom of the planting trough. Under the action of gravity, the water between the guardrails is discharged, preventing the pipelines and planting trough from being corroded. While protecting the pipelines, it also extends the service life of the modular planting trough. Attached Figure Description

[0020] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that, for those skilled in the art, several modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0021] As one embodiment, a modular bridge railing greening planting trough device is proposed, such as... Figure 1-4As shown, the structure includes: modular planting troughs 5, a main irrigation pipe 15, and T-shaped irrigation pipes; the bridge central divider guardrail structure includes guardrails 4, a bottom guardrail 3, and bridge deck paving 2; guardrails 4 are installed on the bottom guardrail 3, and several modular planting troughs 5 are spaced apart along the bridge direction between the guardrails 4; the upper sidewall of the modular planting trough 5 is attached to the sidewall of the guardrail 4, and a gap is left between the lower sidewall of the modular planting trough 5 and the sidewall of the guardrail 4, with the main irrigation pipe 15 installed in the gap; the T-shaped irrigation pipes are located at the intervals of the modular planting troughs 5, and the T-shaped irrigation pipes are vertical. It is directly connected to the main irrigation water pipe 15; the top of the modular planting trough 5 extends outward to form a flange structure, and the bottom of the flange structure fits with the top of the guardrail 4; the upper side wall of the modular planting trough 5 is provided with a lifting hole 6, which is located in the interval between the modular planting troughs 5; the lifting hole 6 is used in conjunction with mechanical lifting to improve construction efficiency; the bottom side wall of the guardrail 4 is pre-embedded with a pre-embedded bracket 16, which is located in the gap between the lower side wall of the modular planting trough 5 and the side wall of the guardrail 4, and the pre-embedded bracket 16 supports the municipal pipeline 14 and the main irrigation water pipe 15;

[0022] Modular planting troughs 5 allow for quick disassembly and maintenance of individual troughs or complete replacement of the entire modular planting trough, greatly reducing interference with bridge traffic, simplifying construction and maintenance processes, and effectively reducing overall maintenance costs and operational difficulties. By integrating the modular planting troughs 5 with the guardrails 4, the modular planting troughs 5 isolate the greenery from the guardrails 4, preventing direct contact between the soil in the planting troughs 5 and the guardrails 4. This prevents moisture and acid / alkaline substances in the soil from corroding the guardrails 4, reducing cracking, rust, and damage caused by erosion, thereby extending the lifespan of the guardrails. Extended service life of the guardrail reduces maintenance costs and enhances its safety and durability. Simultaneously, the pipeline is placed on the pre-embedded bracket 16 between the modular planting trough 5 and the guardrail 4. The modular planting trough 5 and the guardrail 4 act as a rigid protective layer, resisting external impacts, rainwater erosion, and daily wear, significantly improving the pipeline's operational safety and service life. The modular planting trough 5 is secured to the guardrail 4 via a flange structure. Combined with the lifting holes 6 of the modular planting trough 5, pipeline maintenance can be performed quickly by simply lifting the corresponding modular planting trough 5, improving maintenance efficiency and convenience.

[0023] Modular planting trough 5 is made of stainless steel plate. Stainless steel is lightweight, sturdy, durable, and easy to clean, making it suitable for bridge environments and possessing good durability. The shape of modular planting trough 5 is adjusted according to the shape, height, and number of pipelines of guardrail 4, and the number of lifting ports is set according to the lifting requirements. When the planting trough is long, the thickness of the stainless steel plate is adjusted or stiffening plates are added inside the modular planting trough 5 to meet the strength, rigidity, and stability requirements of the modular planting trough 5 during the lifting process.

[0024] like Figure 1 and Figure 3As shown, the modular planting trough 5 is divided into an upper modular planting trough 5 and a lower modular planting trough 5. The bottom 5 of the upper modular planting trough is wider than the top of the lower modular planting trough 5. The modular planting trough 5 is filled from bottom to top with a pebble drainage layer 7, a fine sand filter layer 8, and planting soil 9. Plants 17 are planted on the planting soil 9. The pebble drainage layer 7 and the fine sand filter layer 8 are filled in the lower modular planting trough 5, and the planting soil 9 is filled in the upper modular planting trough 5. The height of the planting soil 9 is lower than the height of the lifting hole 6. The bottom of the pebble drainage layer 7 is... A permeable geotextile 11 is laid; the bridge deck pavement 2 is on both sides of the bottom layer 3 of the guardrail; there is a gap between the bottom of the modular planting trough 5 and the bottom layer 3 of the guardrail; the bottom of the modular planting trough 5 is higher than the bridge deck pavement 2; each modular planting trough 5 has two 30mm drainage holes 10 at the bottom with a spacing of 500mm along the bridge direction; the bottom of the drainage holes 10 is higher than the bridge deck pavement 2; there is a gap between the bottom of the pre-embedded bracket 16 and the bottom layer 3 of the guardrail; drainage pipes 13 run through the inner and outer sides of the guardrail 4; a rain grate 12 is provided at the connection between the drainage pipe 13 and the inner wall of the guardrail 4.

[0025] The permeable geotextile 11 prevents the loss of planting soil while allowing water in the modular planting trough 5 to quickly permeate to the drainage hole 10 at the bottom of the planting trough. Under the action of gravity, the water between the guardrails 4 is drained, preventing the pipelines and the modular planting trough 5 from being eroded. This protects the pipelines and extends the service life of the modular planting trough 5.

[0026] like Figure 1 and Figure 2 As shown, the T-shaped irrigation pipe is divided into an upper T-shaped irrigation pipe and a lower T-shaped irrigation pipe, which are connected by a rotary joint 19. During hoisting construction, the upper T-shaped irrigation pipe is not installed temporarily. It is installed after the modular planting trough 5 is installed. The rotary joint 19 prevents damage to the upper T-shaped irrigation pipe during hoisting. The bottom of the lower T-shaped irrigation pipe is connected to the main irrigation pipe 15. The bottom of the upper T-shaped irrigation pipe is connected to the rotary joint 19. The top of the upper T-shaped irrigation pipe is divided into irrigation branch pipes 18, which extend into the modular planting trough 5, so that the water in the main irrigation pipe 15 irrigates the plants 17 in the modular planting trough 5.
