Description

Technical Field

[0001] This utility model belongs to the field of ecological slope protection technology, specifically relating to a greening and planting structure for bare rock slopes. Background Technology

[0002] With the construction of infrastructure and the development of natural resources, environmental problems are often left behind after the completion of projects. Among them, the problem of exposed rock slopes is particularly prominent. Since rock slopes are generally steep slopes with no conditions for plant growth, it is difficult to regenerate and restore vegetation in the exposed areas, which easily leads to soil and water loss.

[0003] Chinese patent CN220799234U discloses a planting trough for rock slopes, comprising a shell, a base plate fixedly connected to the inner wall of the shell, a baffle fixedly connected to the outer side of the base plate, a partition fixedly connected to the lower side of the base plate, an opening on the inner side of the partition, a liquid collection shell fixedly connected to the outer side of the shell, a filter screen fixedly connected to the inner side of the liquid collection shell, a cavity groove formed on the inner side of the shell, a through hole connected to the inner side of the cavity groove, a guide strip fixedly connected to the outer side of the shell, sealing guide blocks fixedly connected to both sides of the inner side of the cavity groove, a liquid hole formed on the inner side of the shell, a one-way valve installed on the inner side of each liquid hole, and a liquid channel connected to the other end of each liquid hole; the planting trough achieves convenient rainwater collection and is unaffected by the steepness of the rock slope through the designed liquid collection shell, filter screen, baffle, and guide strip.

[0004] However, in actual use, since most rock slopes are sloping and planting holes are usually opened perpendicular to the slope, the shell installed in the planting hole is higher at one end and lower at the other. After rainwater enters the shell through the water collection structure such as the liquid collection shell to replenish the nutrient soil, the excess rainwater cannot be drained and will continue to accumulate at the roots of the plants. The accumulated rainwater is prone to causing the roots of the plants to rot, thus affecting the survival of the plants. In other words, although the above solution can effectively collect rainwater, its drainage capacity is poor and it is not conducive to practical use. Utility Model Content

[0005] The present invention aims to provide a greening planting structure for bare rock slopes to solve the problem of poor drainage capacity in the prior art mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a greening planting structure for bare rock slopes, installed in planting holes on bare rock slopes, including...

[0007] The planting box is installed in the planting hole. A base plate is horizontally installed inside the planting box. Drainage holes are opened on the base plate. Non-woven fabric is laid on the base plate. There is a water storage space between the base plate and the planting box. The water storage space has a water outlet near the opening of the planting box.

[0008] The lower baffle is fixed to the side of the base plate near the drainage hole, and the lower baffle is perpendicular to the bare rock slope;

[0009] Absorbent swabs are installed on top of the substrate, with the ends of the swabs extending to the bottom of the water storage space.

[0010] The principle and effects of this technical solution:

[0011] 1. By horizontally setting the base plate inside the inclined planting box, a water storage space is created between the base plate and the planting box. With a water outlet, the water in the storage space can flow out from the outlet after reaching the bottom of the base plate, thus avoiding excessive water accumulation that could cause the roots of the plants to rot. This improves the survival rate of the plants and makes the device more practical to use.

[0012] 2. By setting up a substrate, drainage holes, and non-woven fabric, the nutrient soil can be placed on the non-woven fabric, and rainwater can enter the water storage space under the substrate through the non-woven fabric. The installation of absorbent cotton strips ensures that the rainwater accumulated in the water storage space keeps the absorbent cotton strips moist, and the moist absorbent cotton strips can replenish the nutrient soil without over-watering, thereby making full use of the water in the water storage space.

[0013] 3. By setting up the lower baffle, rainwater can not only pass through the bare rock slope or directly enter the planting box, but also be intercepted and blocked by the lower baffle, so that the rainwater flows to the base plate and enters the water storage space through the drainage holes. The lower baffle can also intercept and block the collapsed soil to prevent soil loss.

[0014] The present invention is further configured such that: an upper baffle is installed on the upper part of the inner side of the planting box, the end of the upper baffle extends to the outside of the opening of the planting box, there is a water replenishment space between the upper baffle and the planting box, there is a water replenishment port near the opening of the planting box in the water replenishment space, a water replenishment hole is opened on the upper baffle, a sponge pad is installed in the water replenishment space, and the top of the water-absorbing cotton strip is connected to the bottom of the upper baffle.

[0015] The principle and effect of this technical solution: The upper baffle allows rainwater to be absorbed and replenished not only from below, but also to permeate to the top of the nutrient soil through the water replenishment holes in the water replenishment space. This makes the nutrient soil more evenly watered during rain. The sponge pad can further absorb and store rainwater, so that after the rain stops, rainwater can be replenished to the nutrient soil through contact infiltration.

[0016] The present invention is further configured such that: a first cover plate is rotatably installed at the water inlet, a torsion spring is provided at the rotation center of the first cover plate, and the end of the torsion spring is connected to the planting box.

[0017] The principle and effect of this technical solution are as follows: By setting up a torsion spring and a first cover plate, when rainwater continues to flow at the water inlet outside the upper baffle during rainy weather, the weight of the rainwater itself can drive the first cover plate to rotate, overcoming the restoring force of the torsion spring. This allows the rainwater to enter the water replenishment space and be absorbed by the sponge pad. It also replenishes the nutrient soil in the planting box through the water replenishment hole. After the rain stops, the rotation of the torsion spring can drive the first cover plate to return to its original position, thereby closing the water inlet. This prevents the rainwater in the sponge pad within the water replenishment space from coming into contact with the outside, allowing the moisture in the sponge pad to be absorbed and utilized by the nutrient soil to a greater extent, thus improving the utilization rate of rainwater.

[0018] The present invention is further configured such that: a filter screen is installed at the opening of the planting box, the bottom of the filter screen abuts against the substrate, and a planting opening is provided on the filter screen.

[0019] The principle and effect of this technical solution: The filter screen can block the soil at higher and upstream levels, preventing soil loss after collapse, and the planting opening can allow the green plants to grow normally without affecting the normal use of the planting box.

[0020] The present invention is further configured such that: an insert plate is installed on the side of the filter screen near the inner side of the planting box, and the insert plate is located upstream of the planting opening.

[0021] The principle and effect of this technical solution: The setting of the insert plate can prevent the soil inside the filter screen located upstream from collapsing and falling from the planting opening, thereby reducing soil loss. Furthermore, by inserting the insert plate into the soil, the soil compaction near the planting opening is improved, further preventing soil loss.

[0022] The present invention is further configured such that: a water baffle is installed at the bottom of the lower baffle, and a drain outlet is provided on the water baffle to seal the water outlet.

[0023] The principle and effect of this technical solution: By setting up the baffle plate and the drain outlet, the opening of the water outlet is reduced, thereby reducing the area of ​​the water storage space in direct contact with the outside world. This makes the water in the water storage space evaporate more slowly when the rain stops, which increases the storage time of rainwater in the water storage space without affecting the normal discharge of excess rainwater.

[0024] The present invention is further configured to include a second cover plate, the second cover plate being shaped like a "7" and rotatably installed in the water storage space, with the rotation center located at the corner of the second cover plate. The second cover plate includes a floating end and a blocking end, the blocking end corresponding to the water outlet, and the floating end extending to the depth of the water storage space and having a fixed float ball.

[0025] The principle and effect of this technical solution: The second baffle plate in the shape of a 7 rotates around the pivot point, causing the floating end to rotate due to the rising water level. This prevents the baffle from blocking the outlet, allowing excess rainwater in the storage space to drain out through the drain. After the rain stops, as the amount of rainwater in the storage space decreases, the water level drops, causing the floating end to rotate and seal the outlet, i.e., the drain. This allows the water vapor from the accumulated rainwater to be absorbed by the nutrient soil on the substrate, thereby improving the utilization capacity of rainwater. Attached Figure Description
