Description

Technical Field

[0001] This utility model relates to the technical field of concrete planting boxes, specifically to a high-performance precast concrete planting box. Background Technology

[0002] Slope protection for highways is a key technical measure to ensure the stability of the roadbed and the reliable service life of the highway. To improve construction efficiency, current construction methods often involve installing prefabricated drainage ditches and planting boxes.

[0003] Existing similar technologies, such as Chinese patent publication number CN218713271U, disclose a retaining wall for mountain restoration. By setting up a retaining structure, rainwater can be introduced into the planting box through a water outlet pipe, thereby replenishing the water for the green plants inside the planting box, reducing the frequency of watering by landscaping personnel, and reducing watering costs. However, although this patent makes full use of the water in the drainage ditch, the drawback is that the water in the drainage ditch will repeatedly flush the inside of the planting box, causing the soil and water inside the planting box to become increasingly serious. The planted plants will wither after lacking the necessary soil, and replanting plants not only requires labor input but also increases the maintenance cost of the road. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-performance precast concrete planting box, which can reduce the maintenance cost of highways.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-performance precast concrete planting box, comprising a planting box body, an absorbent sponge, and a geogrid; the planting box body has a U-shaped structure, with a partition on its inner side dividing the inner side of the planting box body into a drainage channel and a water collection channel; the partition has through holes to connect the drainage channel and the water collection channel; the absorbent sponge is laid on the bottom wall of the water collection channel and its position corresponds to the through holes; the geogrid is pressed onto the absorbent sponge to support the soil layer required for planting.

[0006] Preferably, the through hole is located on the lower side of the geogrid.

[0007] Preferably, the bottom wall of the drainage trough is higher than the bottom wall of the water accumulation trough.

[0008] Preferably, two support plates are provided on the inner side wall of the water collection trough; the geogrid is erected and fixed at the lower end of the support plates.

[0009] Preferably, the geogrid and the support plate are fixedly connected by screws.

[0010] Preferably, the mesh count of the geogrid is in the range of ~.

[0011] Preferably, the geogrid is made of plastic or fiberglass.

[0012] Preferably, the geogrid has a corrugated structure.

[0013] Preferably, the top of the planting box body is provided with a step for placing a rain grate, and the step is located on the upper side of the drainage channel.

[0014] Preferably, the planting box body has a concave connector at the front end and a convex connector at the rear end, with the convex connector and the concave connector cooperating.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by setting up interconnected drainage channels and water collection channels inside the planting box, and laying geogrids and water-absorbing sponges to support the soil layer in the water collection channel, the soil layer can obtain water from the drainage channel. At the same time, the soil layer can also filter the water entering the drainage channel, reducing soil erosion. In the later stage, it is not necessary to frequently water or replant the plants, thereby reducing the road maintenance cost. Attached Figure Description

[0020] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0021] See Figure 1-3In one embodiment of this utility model, a high-performance precast concrete planting box includes: a planting box body 1, an absorbent sponge 2, and a geogrid 3; the planting box body 1 has a U-shaped structure, and a partition 12 is provided on its inner side, dividing the inner side of the planting box body 1 into a drainage channel 15 and a water collection channel 16; the partition 12 has multiple through holes 18 to connect the drainage channel 15 and the water collection channel 16; the absorbent sponge 2 is laid on the bottom wall of the water collection channel 16; the soil layer 4 pressed on the absorbent sponge 2 is used to support the planting. The bottom wall of the drainage channel 15 is higher than the bottom wall of the water collection channel 16, so that the water collection channel 16 can always accumulate more water than the drainage channel 15, ensuring the normal water supply for the plants.

[0022] Specifically, the planting box body 1 includes a left side plate 11, a right side plate 13, a bottom plate 14, and two support plates 17. The left side plate 11 and the right side plate 13 are vertically mounted on the bottom plate 14, and the partition plate 12 is located between the bottom plates 14. It can be understood that the main end faces of the left side plate 11, the right side plate 13, and the partition plate 12 are parallel to each other. The two support plates 17 are placed on the left side plate 11 and the partition plate 12 respectively. After installation, the geogrid 3 is erected and fixed at the lower end of the support plate 17. In practice, the geogrid 3 and the support plate 17 are fixedly connected by screws.

[0023] Furthermore, a step for placing a rain grate is provided on the top of the upper side of the drainage channel 15, that is, the top of the partition 12 and the right side plate 13.

[0024] This planting box serves both as a plant support and drainage system. To form a continuous ditch, multiple planting boxes need to be connected end to end. To ensure a tight connection between adjacent planting boxes and prevent water leakage, the planting box body 1 has a concave connector at the front end and a convex connector at the rear end, with the convex connector and concave connector working together.

[0025] Multiple through holes 18 are located on the lower side of the geogrid 3. The advantage of this design is that the water in the drainage channel 15 will not directly contact the soil layer on the geogrid 3 through the through holes 18, but will instead penetrate into the soil layer through the water-absorbing sponge 2, reducing the direct scouring of the soil layer by the water in the drainage channel 15 and preventing soil erosion. It can be understood that multiple through holes 18 are sealed by the water-absorbing sponge 2.

[0026] In one embodiment, the geogrid 3 has a mesh count ranging from 20 to 100, which can provide effective support for the soil layer. Furthermore, to improve the service life of the geogrid 3, it can be made of plastic or fiberglass.

[0027] In one embodiment, the geogrid 3 has a corrugated structure, which can increase the contact surface between the geogrid 3 and the soil layer and the water-absorbing sponge 2, so that the water in the water-absorbing sponge 2 can penetrate into the soil layer more efficiently.

[0028] When this planting box is installed on both sides of the road, the drainage ditch 15 is positioned close to the road, allowing water from the road to drain directly into the drainage ditch 15, ensuring normal vehicle passage. Water in the drainage ditch 15 enters the water collection ditch 16 through the through hole 18, and is absorbed by the plants after passing through the water-absorbing sponge 2 and geogrid 3. Conversely, when water from the outside of the road enters the water collection ditch 16, it must pass through the plants, soil, geogrid 3, and water-absorbing sponge 2 in sequence before finally flowing into the drainage ditch 15. Due to the blocking effect of the water-absorbing sponge 2 and geogrid 3, not only can soil from the soil layer be effectively prevented from flowing into the drainage ditch 15, but larger debris can also be prevented from entering the drainage ditch 15 and causing blockage, ensuring the water conveyance capacity of the drainage ditch 15.

[0029] This technical solution involves setting up interconnected drainage and water collection channels inside the planting box. The water collection channel is lined with geogrids and absorbent sponges to support the soil layer, allowing the soil layer to obtain water from the drainage channel. At the same time, the soil layer can also filter the water entering the drainage channel, reducing soil erosion. This eliminates the need for frequent watering or replanting of plants, thereby reducing road maintenance costs.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
