Description

Technical Field

[0001] This invention relates to the technical field of road medians, specifically to a plant stand for urban expressway medians, and also provides a method for using the plant stand. Background Technology

[0002] Expressways are two-way, multi-lane roads with a central median and grade-separated interchanges at all entrances and exits, serving a large volume of long-distance, high-speed traffic in cities. To improve road efficiency and optimize urban traffic conditions, large and medium-sized cities often construct ring roads on their outskirts or expressways that traverse the city center.

[0003] Under current urban road traffic management regulations, expressways are the main routes for large intercity freight trucks and vehicles undertaking urban transportation tasks. Therefore, the mixing of various types of freight vehicles and private cars is common on expressways. The vegetation planted in expressway medians is usually tailored to local conditions, selecting plants that are easy to maintain, aesthetically pleasing, or provide excellent shading. In areas with higher latitudes and larger annual temperature variations, the selection of vegetation in the median strip is limited. To prevent leaf and branch drop due to low temperatures, which would weaken the separation and shading effect, cold-resistant and drought-resistant evergreen plants are typically planted. These include low shrubs and pine trees, which provide more dense shading, covering both high and low areas. In areas planted with low shrubs, due to the size of freight vehicles and the frequent improper use of high beams and modified headlights by private vehicles, oncoming headlights can cause glare, potentially leading to serious traffic accidents.

[0004] Therefore, setting up an anti-glare vertical greening structure is a necessary and urgent requirement for the median strip of expressways. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a plant placement rack for urban expressway medians, which allows for the convenient installation of vertical greening structures among low shrubs in the expressway median, ensuring that the headlight status on both sides of the median does not interfere with each other, and enabling safe passage at night.

[0006] A plant stand for use in the median strip of an urban expressway, characterized in that it comprises:

[0007] The base includes a base and upward-protruding base legs;

[0008] The platform is a skeletal structure consisting of a base frame and an upright frame.

[0009] And sandwich structures;

[0010] The base frame includes a central positioning plate and two side frames. The central positioning plate is located directly above the base and has pre-drilled alignment holes at the positions of the base legs. The upright frame includes columns at the four corners, an upper rectangular frame, and cultivation troughs arranged diagonally upwards on both sides. The sandwich structure is inserted into the vertical frame of the upright frame.

[0011] Its further features are:

[0012] The sandwich structure includes a sound insulation board and a light-shielding board, with the light-shielding boards arranged on the outside of the sound insulation board to form a light-shielding and sound-insulating structure.

[0013] The base is a permeable concrete base;

[0014] A retaining strip is provided along the outer edge of the cultivation trough.

[0015] A method for using a plant placement rack for urban expressway medians is characterized by the following: the base and frame are prefabricated structures. During installation, the prefabricated base is placed into a pre-reserved pit in the shrubbery of the median strip. Geotextile filter cloth is laid on top of and around the base, with holes corresponding to the base legs on the geotextile filter cloth. The soil around the base is then compacted, exposing the base legs. The frame is then placed on top, and the base legs are inserted through the pre-reserved alignment holes in the frame, ensuring that the frame cannot move horizontally.

[0016] After installation, spread soil on top of the base to further secure the base and the frame structure. Plant vegetation in the gaps between the frames and place cultivated flower pots in the cultivation troughs. Insert the sandwich structure into the gaps between the frames from above.

[0017] Its further features are:

[0018] When the sandwich structure is installed, corresponding sandwich structures are set on both sides of the vertical frame of the upright frame. The sandwich structure formed by the combination of sound insulation board and light shield is inserted into the area on both sides of the vertical frame of the upright frame. The upright frame of the platform is stabilized by the columns, beams and the convex base legs. The light shield is arranged facing outward.

[0019] Check the condition of each component periodically. When replacing, remove the flowerpot from the cultivation trough, dig out the planter planted in the gap of the base structure, remove the stand that is movably connected to the base legs, and replace as needed.

[0020] With the present invention, it is convenient to set up vertical greening structures among low shrubs in the median strip of expressways, so as to achieve the result that the status of vehicle lights on both sides of the median strip does not affect each other, and to achieve safe passage at night.

Detailed Implementation

[0027] A plant stand for use in the median strip of an urban expressway, see Figures 1-4 It includes: a base 10, a frame 20, and a sandwich structure 30;

[0028] The base 10 includes a base 11 and two spaced-apart upward-protruding base legs 12. The base 11 is a permeable concrete base. The platform 20 is a skeleton structure composed of a base frame 21 and an upright frame 22. The sandwich structure 30 includes a sound insulation board 31 and a light-shielding board 32. The light-shielding board 32 is located on the outside of the sound insulation board 31 to form a light-shielding and sound-insulating structure.

[0029] The base frame 21 includes a central positioning plate 211 and two side frames 212. The central positioning plate 211 is located directly above the base 10 and has a pre-drilled alignment hole 121 at the position of the base support leg 12. The upright frame 22 includes columns 221 at the four corners, an upper rectangular frame 222, and cultivation troughs 223 arranged diagonally upward on both sides. The sandwich structure 30 is inserted into the vertical frame of the upright frame 22.

[0030] In practice, the light-shielding board 32 is a functional rock wool board, the sound insulation board 31 is an FC sound insulation board, and the edge of the cultivation trough 223 is equipped with a baffle 2231 to prevent flower pots or plants from falling out of the cultivation trough.

[0031] A method for using a plant support frame for urban expressway medians: The base 10 and the frame 20 are prefabricated structures. During installation, the prefabricated base 10 is placed into a pre-reserved pit in the median shrubbery. Geotextile filter cloth is laid on top of and around the base 10. The geotextile filter cloth has clearance holes corresponding to the base legs 12. The soil around the base 10 is filled in, exposing the base legs 12. Then, the frame 20 is placed on the base 10, and the base legs 12 are inserted into the pre-reserved alignment holes of the frame 20, ensuring that the frame 20 cannot move horizontally. After installation, soil is laid on top of the base 10. The base 10 and the base frame 20 are fixed with soil again, and vegetation is planted in the gap between the base frame 21 structure of the base 20. The cultivated flower pots are placed in the cultivation trough 223. The two-layer sandwich structure is placed in the sandwich space formed by the upright frame 22 and the base support leg 12 from above. Specifically, the FC sound insulation board structure and the functional rock wool board structure are inserted into the gaps on both sides formed by the base 20 and the base support leg. The uprights, beams and the protruding base support leg 12 of the upright frame 22 of the base are used to stabilize the overall position and prevent swaying or even displacement due to the existence of gaps.

[0032] Check the condition of each component periodically. When replacing, remove the flowerpot from the cultivation trough 223, dig out the plant from the gap in the base frame 21, remove the stand 20 that is movably connected to the base support leg 12, and replace it.

[0033] The beneficial effects of using this invention are as follows:

[0034] 1. Increase green area and enhance the aesthetics of urban expressways. The rational application of vertical greening technology in the landscape design of urban roads can not only increase the green area in the central median, but also make the green area more layered.

[0035] 2. Effectively prevents glare and reduces noise: Existing median barriers and low vegetation heights inevitably create glare from oncoming vehicles on roads with varying elevations and when large vehicles are passing. The vertical greening structure provided by this invention is placed among tall vegetation, without affecting the light requirements and daily maintenance of the tall vegetation, and can block the path of light transmission between tall plants. Furthermore, this invention, through its four-layer structure—vegetation, soil, metal frame, FC sound insulation board, and functional rock wool board—from the outside in, has significant heat insulation, fire resistance, and sound absorption properties, effectively reducing the noise from high-speed vehicles and freight vehicles. Especially in northern regions, its anti-glare and noise reduction effects are not affected after the vegetation withers and dies in winter.

[0036] 3. Low cost and easy installation: The installation of this invention can be roughly divided into three steps: base installation, vertical module frame installation, and planting and placement of vegetation. The base and frame are reusable equipment and prefabricated accessories. Compared with the vertical greening structures applied to buildings and overpasses, the metal keel structure, FC sound insulation board structure and functional rock wool board structure used have low cost.

[0037] 4. This invention reduces the maintenance difficulty of vertical greening, applying the technology to urban roads. It takes into account the dimensions and height of passenger and freight vehicles, combined with some urban rapid transit design requirements. The height of the base and frame of the vertical greening system provided by this invention does not exceed 3m, and the soil height in the planting area is a maximum of 2.2m. Soil replacement and fertilization can be done manually, and it can be maintained using general municipal landscaping maintenance vehicles, reducing the chance of plant wilting and death.
