Description

Technical Field

[0001] This utility model belongs to the field of slope restoration technology, specifically relating to a planting platform for rocky slopes. Background Technology

[0002] There are often exposed rock slopes on both sides of rivers and highways. Because they usually have a large slope and a large height difference, they are not suitable for covering with soil and planting vegetation. They are called high rock slopes. Under the influence of the external environment, they are prone to geological disasters such as weathering and erosion, rock and mud flow, falling rocks, and collapse. Therefore, it is necessary to repair and stabilize them to reduce or avoid such disasters.

[0003] The traditional approach involves creating platforms (horse trails) by tiered slope cutting and establishing planting platforms. Various measures are then used to plant grass on the slopes. These platforms and vegetation buffer and shield the slopes, reducing the threat of landslides. However, the construction of planting platforms mainly uses masonry and concrete structures, which takes a long time. Furthermore, when the construction schedule is tight, subsequent slope cutting and blasting operations may be carried out before the existing concrete structure has reached sufficient curing strength, potentially causing vibration damage to the concrete structure. This results in poor stability and reliability, making it unsuitable for practical use. Utility Model Content

[0004] The present invention aims to provide a planting platform for rocky slopes to solve the problems of long construction period and poor stability of existing planting platforms mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a planting platform for rocky slopes, installed on a walkway, comprising...

[0006] The enclosure includes posts and corrugated sheets. Multiple posts are installed at intervals on the walkway, and two adjacent posts share a corrugated sheet. A sealing component is installed at the gap between the bottom of the corrugated sheet and the top surface of the walkway.

[0007] The planting area is located on one side of the corrugated sheet. The planting area includes a water-retaining layer, a planting soil layer and an anti-erosion layer arranged from bottom to top. The water-retaining layer is installed on the walkway. A water-guiding layer is installed on the side of the planting soil layer away from the corrugated sheet. The upper and lower ends of the water-guiding layer abut against the water-retaining layer and the anti-erosion layer, respectively.

[0008] The main body of the intercepting ditch is installed on the planting soil layer and located on the side of the erosion control layer near the corrugated plate. The top edge of the main body of the intercepting ditch is not higher than the top edge of the erosion control layer.

[0009] The principle and effects of this technical solution:

[0010] 1. The planting area is enclosed by columns and corrugated sheets, with the columns providing support for the corrugated sheets. The corrugated sheets enclose the planting area, thus providing a shielding effect. Compared with methods such as pouring concrete, the construction of columns is faster and has a shorter cycle. Furthermore, during subsequent slope cutting operations, the blasting vibrations can be buffered and reduced by the vibrations of the corrugated sheets, resulting in minimal impact on the overall enclosure formed by the columns and corrugated sheets and no structural damage.

[0011] 2. The water-retaining layer can store water and retain moisture, reducing the frequency of manual watering. The soil covering layer provides a planting base for green plants, and the erosion-resistant layer can prevent rainwater and slope runoff from directly eroding the planting soil layer, thus reducing soil erosion. The water-conducting layer can accelerate the flow of water from the slope into the water-retaining layer, so that the water can be fully absorbed by the planting area.

[0012] 3. The intercepting ditch can guide and drain excess water from the planting area, preventing excess water from overflowing the corrugated plate and continuing to flow down the slope. By guiding and draining, the effect of rainwater eroding the slope in stages is reduced, thereby improving the stability of the slope structure.

[0013] The present invention is further configured such that: the sealing component includes a wire mesh bag filled with crushed stones, the wire mesh bag is fixed to the bottom of the corrugated plate and located in the gap between the corrugated plate and the walkway.

[0014] The principle and effect of this technical solution: By using a wire mesh bag filled with crushed stones to cover the gap between the corrugated sheet and the walkway, it can easily cover the narrow gap, so that when the water-retaining layer is installed later, the material of the water-retaining layer will not flow out from the gap. Moreover, the solution can seal the narrow gap quickly and conveniently.

[0015] The present invention is further configured such that: the sealing component includes masonry blocks, which are fixed on the walkway and located in the gap between the corrugated plate and the walkway.

[0016] The principle and effect of this technical solution: By using mortar-grouted masonry blocks to cover the wider gaps, a better sealing effect is provided, which in turn provides a good sealing effect when setting up a water-retaining layer, and at the same time improves the water-locking capacity; the mortar-grouted masonry casting with lower height, thinner thickness and more flexible length is simpler and faster than the original large-scale and large-size casting, and has lower requirements for strength and other aspects, making construction simple.

[0017] The present invention is further configured such that: multiple drill holes are arranged at intervals on the walkway, the distance from the center of the drill hole to the outer side of the walkway is 0.45-0.55m, the diameter of the drill hole is larger than the diameter of the column, and the column is anchored in the drill hole.

[0018] The principle and effect of this technical solution: By limiting the distance from the borehole to the outside of the horse trail, the impact of the collapse of the slope connected to the outside of the horse trail on the borehole is reduced. Moreover, after the borehole penetrates deep into the horse trail, the horizontal distance between the bottom of the borehole and the slope is relatively large, so the anchor rod can be stably supported and fixed inside the borehole.

[0019] The present invention is further configured such that the distance between the drill holes at both ends of the walkway and their adjacent drill holes is 1.8-2.2m, and the distance between the remaining drill holes on the walkway and their adjacent drill holes is 3.8-4.2m.

[0020] The principle and effect of this technical solution: By controlling the spacing between the drill holes, the corrugated plate can provide stable support for the internal planting area. The reasonable spacing can reduce the number of drill holes, columns and corrugated plates required, which reduces the amount of construction work and construction costs. The setting of a spacing of 1.8-2.2 meters at the edges can reduce the wingspan of the corrugated plates on both sides of the column (i.e., reduce the lever arm length) to provide more stable support strength.

[0021] The present invention is further configured such that: the water-retaining layer is a foamed concrete layer mixed with vermiculite, the mixing ratio of vermiculite and foamed concrete is 1:1, and the total thickness of the foamed concrete layer mixed with vermiculite is 200-250mm, and the size of the vermiculite is 20-40 mesh.

[0022] The principle and effect of this technical solution: By setting vermiculite and foamed concrete in a 1:1 ratio, the water-retaining layer can prevent soil erosion. Due to the porous nature of vermiculite and foamed concrete, it can absorb water, thus storing a certain amount of water. The stored water is then transferred to the planting soil layer through evaporation and soil water absorption. Vermiculite has good ion exchange properties, which can enrich nitrogen, phosphorus, potassium, aluminum, iron, magnesium and other components through ion exchange to provide nutrients to the planting soil layer. It does not rot over a long period of use, is lightweight, and a thickness of 200mm can achieve a good water retention effect. Furthermore, 20-40 mesh vermiculite can achieve better water retention and nutrient enrichment without compromising the strength of the water-retaining layer.

[0023] The present invention is further configured such that: the top edge of the anti-erosion layer on the side away from the corrugated plate is higher than the top edge on the side closer to the corrugated plate; the slope of the anti-erosion layer is not less than 5°; and the top edge of the anti-erosion layer is not higher than the top edge of the corrugated plate; both the water-conducting layer and the anti-erosion layer are gravel layers, and both have a thickness of 90-110mm.

[0024] The principle and effect of this technical solution are as follows: By making the height of the anti-erosion layer on the side closer to the intercepting ditch body lower than the height on the side farther away from the intercepting ditch, the amount of soil cover can be increased without causing soil erosion, thus increasing the amount of soil in the planting soil layer to support vegetation growth and survival. During rainy days, when excessive rainwater accumulates in the planting area, the excess rainwater can be discharged by flowing into the intercepting ditch body after overflowing the surface of the planting area. The anti-erosion layer and water-conducting layer composed of gravel can accelerate the flow of water into the planting soil layer and water-retaining layer. At the same time, the anti-erosion layer will not interfere with the growth of green plants and can also directly contact the rainwater flowing down the slope. Through the buffer between the gravel, the scouring force of rainwater entering the planting soil layer can be reduced, thereby reducing the scouring force on the soil in the planting soil layer.

[0025] The present invention is further configured such that the width and depth of the intercepting ditch body are 200mm*200mm respectively.

[0026] The principle and effect of this technical solution: By making the intercepting ditch 200mm wide and deep, it has sufficient capacity for water collection and drainage during rainy days, so as to prevent rainwater from sliding down the slope and excessively eroding the slope.

[0027] The present invention is further configured such that a waterproof membrane is provided between the water-retaining layer and the walkway.

[0028] The principle and effect of this technical solution: The waterproof membrane can block gaps, cracks and holes in the walkway to prevent water in the water-retaining layer from seeping out through the gaps in the walkway, thus improving the water retention effect of the water-retaining layer.

[0029] The present invention is further configured such that: the side of the planting soil layer closest to the corrugated plate is planted with downward-climbing vines, and the side of the planting soil layer away from the corrugated plate is planted with upward-climbing vines.

[0030] The principle and effect of this technical solution: The slope is covered by climbing plants to achieve a greening effect, so that no further greening treatment is needed. Attached Figure Description

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0041] Example:

[0042] As attached Figure 1-4 As shown, this utility model discloses a planting platform for rocky slopes, set on a walkway 110, including a fence, a planting area, and a drainage ditch body 310. According to the "Technical Specification for Building Slope Engineering", the height of each slope level is usually set at 6.0-10m. In this scheme, the slope height is selected as 6m and the width of the walkway 110 is 2m. The smaller slope height and the 2m width of the walkway 110 can greatly increase the stability of the slope and the safety of construction. At the same time, the slope is conducive to vegetation climbing and coverage.

[0043] Multiple drill holes 111 are spaced apart on the walkway 110. The distance from the center of the drill hole 111 to the outer side of the walkway 110 is 0.45-0.55m. Specifically, 0.45m or 0.55m can be used during construction, with 0.5m being the most suitable. The diameter of the drill hole 111 is φ130mm, and the bottom is sealed with grout. The depth of the drill hole 111 (excluding the thickness of the grout sealing) is 1760mm. The axial distance between the drill hole 111 at both ends of the walkway and its adjacent drill hole 111 is 1.8-2m. The wheelbase can be 1.8m, 2m, or 2.2m. In this design, 2m is used (for edge sealing reinforcement of corrugated plate 220; a shorter wheelbase can reduce the length of the corrugated plate 220's wingspan, thereby reducing the lever arm length and improving stability). The wheelbase between the remaining drill holes 111 on the walkway and their adjacent drill holes 111 is 3.8-4.2m. The wheelbase can be 3.8m, 4.0m, or 4.2m. In this design, 4m is used as an example, in conjunction with the subsequent corrugated plate 220.

[0044] The enclosure includes posts 210 and corrugated plates 220. Multiple posts 210 are respectively installed in drilled holes 111 and anchored in the drilled holes 111 by grouting. The posts 210 are hot-dip galvanized posts 210, with a diameter of φ114mm and a length of 3000mm. Two adjacent posts 210 are installed together with a corrugated plate 220. The corrugated plate 220 is a hot-dip galvanized corrugated guardrail plate, with a length of 4320mm along the length of the walkway 110, a thickness of 2.5mm, and a wave pitch of 310mm. Because the surface of the walkway 110 may have rocks or other unevenness, there may be gaps between the bottom of the corrugated plate 220 and the top surface of the walkway 110 during installation. A sealing component is installed at the gap between the corrugated plate 220 and the walkway 110. (When used on soil slopes, reinforced soil anchors should be used to strengthen the fixing structure between column 210 and walkway 110.)

[0045] When the gap width (length along the length of the walkway 110) between the corrugated plate 220 and the walkway 110 is less than 100mm, a wire mesh cage filled with crushed stones can be used for sealing and blocking, and the wire mesh cage is fixed to the corrugated plate 220.

[0046] When the gap between the corrugated plate 220 and the walkway 110 is wider than 100mm, it is filled and sealed with mortar-grouted masonry blocks (i.e., by pouring stones, sand and gravel).

[0047] The planting area is located on the side of the corrugated sheet 220 near the walkway 110. Construction of the planting area begins after the enclosure is set up. The planting area includes a water-retaining layer 310, a planting soil layer 220, and an anti-erosion layer 230, arranged from bottom to top. The water-retaining layer 310 is installed on the walkway 110, and a water-proof membrane is set between the water-retaining layer 310 and the walkway 110. The water-proof membrane is used to seal the gaps and holes on the walkway 110 to prevent the water-retaining layer 310 from losing moisture.

[0048] The water-retaining layer 310 is a foamed concrete layer mixed with vermiculite. The bottom surface of the planting area is constructed by vermiculite and foamed concrete (also called aerated concrete). The mixing ratio of vermiculite and foamed concrete is 1:1, and the total thickness of the water-retaining layer 310 is 200-250mm. In this scheme, 200mm is used as an example. The size of the vermiculite is 20-40 mesh. Before backfilling the planting soil layer 220, the water-retaining layer 310 needs to be fully water-collected.

[0049] A water-guiding layer 240 is installed on the side of the planting soil layer 220 away from the corrugated plate 220. The upper and lower ends of the water-guiding layer 240 are in contact with the water-retaining layer 310 and the erosion-resistant layer 230, respectively. The water-guiding layer 240, the erosion-resistant layer 230 and the water-retaining layer 310 are all in contact with the inner slope of the walkway 110. By contacting the slope, the water flowing above the slope can be absorbed by the planting area to prevent further spread and erosion of the slope below the walkway 110, thus reducing the erosion effect of rainwater on the slope. The top edge of the erosion control layer 230 on the side away from the corrugated plate 220 is higher than the top edge on the side closer to the corrugated plate 220. The slope of the erosion control layer 230 is not less than 5°, and the top edge of the erosion control layer 230 is not higher than the top edge of the corrugated plate 220. Both the water-conducting layer 240 and the erosion control layer 230 are gravel layers with a thickness of 90-110mm, specifically 90mm, 100mm, or 110mm. In this scheme, a thickness of 100mm is used as an example. The gravel has many gaps, which can buffer rainwater after it washes over the gravel. Water can also easily penetrate into the planting soil layer 220 and the water-retaining layer 310 through the gaps. The gravel will not interfere with the root growth of the vegetation. At the same time, the corrugated plate 220 can also adapt to the increased volume caused by the spread of root growth through local deformation.

[0050] The intercepting ditch body 310 is installed on the planting soil layer 220 and located on the side of the erosion control layer 230 near the corrugated plate 220. The top edge of the intercepting ditch body 310 is not higher than the top edge of the erosion control layer 230. The width and depth of the intercepting ditch body 310 are both 200mm. The intercepting ditch body 310 can be a ready-made product, such as a fiberglass resin intercepting ditch or a quartz sand fiberglass resin intercepting ditch. It can be installed quickly and conveniently on the planting area through prefabricated installation, thereby shortening the construction cycle. The end of the intercepting ditch is connected to the drainage ditch. For slope drainage ditches (slope surface drainage ditches), they should be set as dual-function drainage ditches with drainage and steps for climbing to the top of the slope, which is convenient for later operation and maintenance.

[0051] On the side of the planting soil layer 220 closest to the corrugated plate 220, downward-climbing vines are planted at 1-meter intervals. These can include forsythia, star jasmine, periwinkle, and creeping sedum, among others. Plant selection should comply with local ecological protection requirements. On the side of the planting soil layer 220 furthest from the corrugated plate 220, upward-climbing vines are planted at 1-meter intervals. These can include Virginia creeper, kudzu, ivy, and trumpet vine, among others. Plant selection should also comply with local ecological protection requirements. Shrubs can be planted in the middle of the planting soil layer 220 at 1.5-meter intervals, such as bougainvillea, nandina, and purple acacia, again adhering to local ecological protection requirements. This two-way climbing vine coverage accelerates the greening process on the slope.

[0052] Furthermore, for slope treatment, trellis climbing nets or geogrids combined with dense mesh netting are typically installed to facilitate plant climbing and prevent rocks from rolling down. For slopes with small height values, the slope can usually be fully covered within one year, without the need for further greening or revegetation work.

[0053] The parts of the device not covered herein are the same as or can be implemented using existing technologies.

[0054] Among them, insert and sliding insert are mating bodies with holes, the cross section of the shaft or rod matches the hole, and the shaft or rod can slide relative to the hole. Threaded insert is a hole with threads, the shaft or rod is threaded, and the shaft or rod is connected to the mating body by screwing. Detachable installation can be by bolt thread connection or bolt and nut connection, etc., depending on what can be actually achieved.

[0055] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
