Description

Technical Field

[0001] The utility model relates to a greening structure for slopes, which is applicable to the technical field of ecological restoration. Background Art

[0002] In road engineering construction, in some sections, since the road surface is lower than the ground on both sides, slopes will inevitably be formed on both sides of the road surface, and usually vertical slopes are set to reduce the land occupation of the slopes. In order to make the road have good aesthetics and ecology, ecological restoration needs to be carried out on the slopes on both sides. At present, the main way to repair vertical slopes is to adopt a single slope-foot planting method, that is: climbing plants are planted at the slope feet of the slopes, and they gradually cover the slopes during the growth process, so as to restore the ecology of the slopes. However, due to the slow growth of climbing plants and the long distance from the slope top, the vegetation coverage rate of the slopes is low, the ecological effect is not ideal, and it does not have a certain three-dimensionality and aesthetics. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is: To solve the above technical problem, the utility model provides a greening structure for slopes.

[0004] The technical solution adopted by the utility model is: A greening structure for slopes, characterized in that: a fixing layer is laid on the slope surface of the slope, the side wall of the fixing layer away from the slope is stepped, and planting layers are arranged on each step of the fixing layer;

[0005] The planting layer has a number of installation blocks arranged on the steps of the fixing layer along the length direction of the steps. A cavity is made in the installation block, an opening is made at the top end of the installation block, a soil layer is filled in the cavity of the installation block, plants are planted on the soil layer of the installation block, a water filtering layer is laid on the inner wall of the cavity of the installation block, and a water drainage hole is made on the side wall of the installation block away from the fixing layer. In this way, when the fixing layer is laid on the slope, it can play a good protective role for the slope; after the installation blocks are arranged on each step of the fixing layer, the plants are planted in the soil layer in the cavity of the installation block. The plants in the installation blocks on each step will block and cover the slope during growth, so that the slope has good aesthetics, three-dimensionality and ecology during the plant growth stage, and the excess accumulated water in the cavity of the installation block can be discharged through the water drainage hole.

[0006] The fixing layer has blocks laid on the slope surface of the slope. The blocks are parallel to the bottom surface of the slope, and anchor bolts are arranged on the blocks and anchored into the slope. In this way, it is convenient to connect the blocks with the slope and improve the connection strength between the fixing layer and the slope.

[0007] A bonding layer is arranged between two adjacent blocks and between the block on the bottom surface of the slope and the bottom surface of the slope. In this way, the connection strength between the blocks of the fixing layer and the connection strength between the fixing layer and the bottom surface of the slope are enhanced.

[0008] A bonding layer is provided between the mounting blocks arranged on the building blocks and the building blocks, and between the mounting blocks arranged on the bottom surface of the slope and the bottom surface of the slope.

[0009] The water filtering layer is a permeable geotextile laid on the inner wall of the cavity of the mounting block.

[0010] The beneficial effects of the present utility model are as follows: By paving building blocks on the slope, the side wall of the fixing layer composed of building blocks and away from the slope side is stepped. The building blocks are anchored to the slope through anchor nails, so as to fix the building blocks on the slope, play a supporting role for the slope, and facilitate the subsequent arrangement of the planting layer on the steps of the fixing layer; By evenly paving mounting blocks with cavities on the steps away from the slope side of the fixing layer, after the plants are planted in the soil layer of the cavity of the mounting block, the plants can grow out of the mounting block through the openings on the mounting block during the growth process, so as to achieve a good coverage rate and ecological effect on the slope; By arranging drain holes on the side wall of the mounting block, it is convenient to drain the excess water when there is more water stored in the soil layer in the cavity of the mounting block; By arranging a water filtering layer on the inner wall of the cavity of the mounting block, it can prevent the soil in the cavity of the mounting block from being discharged from the drain holes along with the water body, resulting in soil loss in the mounting block, and at the same time, it can also prevent the soil from entering the drain holes and blocking the drain holes.

[0014] The present utility model will be further described in detail below with reference to the drawings and through embodiments. The following embodiments are explanations of the present utility model, and the present utility model is not limited to the following embodiments.

[0015] This embodiment is a greening structure for a slope 1. The slope 1 in this embodiment is a vertical slope 1.

[0016] In this embodiment, a fixing layer 2 is paved on the slope surface of the slope 1. The fixing layer 2 has building blocks 2-1 paved on the slope surface of the slope 1 in sequence from the foot of the slope 1 upwards. The building blocks 2-1 are parallel to the bottom surface of the slope 1. Anchor bolts 4 are arranged on the building blocks 2-1, and the anchor bolts 4 are anchored into the slope 1. In this way, when the building blocks 2-1 are paved on the slope 1, the building blocks 2-1 are fixed on the slope 1 through the anchor bolts 4, which is convenient for fixing the building blocks 2-1 on the slope 1. At the same time, it can play a supporting role for the slope 1 and also make the surface of the fixing layer 2 composed of each building block 2-1 flat.

[0017] In this embodiment, the upper and lower layers of the building blocks 2-1 are arranged in a staggered manner during the paving process, so that the side wall of the fixing layer 2 composed of the building blocks 2-1 on the side away from the slope 1 is stepped. A planting layer 3 is arranged on each step of the fixing layer 2. Among them, the planting layer 3 has a plurality of mounting blocks 3-1 arranged on the steps of the fixing layer 2 along the length direction of the steps. A cavity is formed in the mounting block 3-1, an opening is formed at the top of the mounting block 3-1, a soil layer 3-2 is filled in the cavity of the mounting block 3-1, plants are planted on the soil layer 3-2 of the mounting block 3-1, a water filtering layer 3-3 is paved on the inner wall of the cavity of the mounting block 3-1, and a water drainage hole 3-4 is formed on the side wall of the mounting block 3-1. The water drainage hole 3-4 is arranged at the bottom position of the mounting block 3-1. In this way, after the mounting blocks 3-1 are paved on the side wall of the fixing layer 2, after the plants are planted in the soil layer 3-2 of the cavities of each mounting block 3-1, the plants will grow upwards through the openings on the mounting blocks 3-1 during growth, so that the plants can be evenly distributed on the slope 1 during growth, maintaining a good coverage rate and ecological effect. The excess water in the cavities of the mounting blocks 3-1 can also be discharged from the water drainage holes 3-4, avoiding water accumulation in the cavities of the mounting blocks 3-1 and affecting the growth of the plants in the cavities of the mounting blocks 3-1.

[0018] In this embodiment, the water filtering layer 3-3 is made of permeable geotextile. In this way, when the excess water in the cavity of the mounting block 3-1 is discharged from the water drainage holes 3-4 on the side wall of the mounting block 3-1, the geotextile can prevent the soil in the cavity of the mounting block 3-1 from being discharged with the water, avoiding soil loss in the cavity of the mounting block 3-1 and soil entering the water drainage holes 3-4 to block the water drainage holes 3-4.

[0019] In this embodiment, a bonding layer 5 is arranged between two adjacent building blocks 2-1 and between the building block 2-1 on the bottom surface of the slope 1 and the bottom surface of the slope 1. The bonding layer 5 in this embodiment is a concrete layer. In this way, when the building blocks 2-1 are paved on the slope surface of the slope 1, under the connection action of the bonding layer 5 between two adjacent building blocks 2-1 and between the building block 2-1 on the bottom surface of the slope 1 and the bottom surface of the slope 1, the structural strength of the fixing layer 2 composed of each building block 2-1 is greatly enhanced.

[0020] In this embodiment, a bonding layer 5 is provided between the mounting block 3-1 arranged on the building block 2-1 and the building block 2-1, and between the mounting block 3-1 arranged on the bottom surface of the slope 1 and the bottom surface of the slope 1. The bonding layer 5 in this embodiment is a concrete layer. In this way, it is convenient to fix the mounting block 3-1 on the fixing layer 2 and prevent the mounting block 3-1 from falling off the fixing layer 2.
