Description

Technical Field

[0001] The utility model belongs to the technical field of revetment buildings, and in particular relates to a novel ecological revetment. Background Art

[0002] Ecological revetment is an artificial revetment that restores the natural river bank or has the characteristics of the natural river bank. It imitates the "permeability" characteristics of the natural shoreline and meets the stability and strength required by the project. The main purpose of the ecological revetment is to restore the natural characteristics of the river bank, ensure species diversity and the stability of the ecosystem. It uses natural materials to form a permeable interface, allowing water exchange and regulation between the river water and the groundwater layer outside the embankment; for example, a Chinese patent discloses a self-healing artificial lake ecological revetment (patent announcement number: CN220868118U), which uses the developed root system of plants to consolidate soil and protect slopes, that is, the roots of aquatic plant seeds grown in the anti-loss plant ecological bag are entangled with the roots planted on the revetment body, so that they are fixedly connected as a whole, so that it is not only simple in structure and easy to implement, but also can prevent soil erosion, meet the needs of ecological environment restoration, and can also be used for artificial landscape.

[0003] Although the above-mentioned ecological revetment can prevent soil erosion, it is only achieved through the entanglement of the plant roots and stems with the revetment body. It takes a period of plant growth before the above-mentioned effect can be achieved. During the growth of plants, the effect of the revetment in preventing soil erosion is not significant. If it encounters the rainy season again, the water flow speed on one side of the revetment will accelerate, which will carry more mud, sand and gravel to impact the plant ecological bags, easily causing damage to them and affecting the effect of preventing soil erosion. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a new type of ecological revetment, which can solve the problem that the ecological revetment in the prior art cannot effectively prevent soil erosion.

[0005] In order to achieve the above object, the utility model provides the following technical solutions:

[0006] A new type of ecological revetment is arranged on a river bank slope, comprising a gravel layer laid on the surface of the bank slope and a plurality of blocks arranged on the upper surface of the gravel layer; the plurality of blocks are arranged in sequence along the length direction of the bank slope at intervals, and are also arranged in sequence along the bank slope toward the river channel, the plurality of blocks cooperate with each other and jointly cover the gravel layer, and any two adjacent blocks in the direction of the bank slope toward the river channel are plugged into each other, and a limiting member for horizontally limiting the block is also provided between the block and the bank slope, a storage chamber is formed between each block and the gravel layer, and an opening connected to the storage chamber is opened on the surface of each block, soil is piled in each storage chamber, and plants are planted in the soil, and the plants grow outward through the opening; a retaining wall for preventing the gravel layer from sliding is vertically arranged between the bank slope and the river channel.

[0007] Furthermore, the stopper is in an "L" shape, and a longer side surface of the stopper is horizontally arranged and inserted into the gravel layer, and the other side surface is vertically arranged and plugged into adjacent stoppers.

[0008] Furthermore, two slots are provided on the horizontal surface of the stopper, and two plug-in blocks cooperating with the slots are provided on the vertical plane of the stopper. The plug-in blocks are vertically arranged and plugged into the slots on the surfaces of adjacent stoppers.

[0009] Furthermore, the stoppers arranged along the length direction of the bank slope are arranged alternately with the upper and lower adjacent stoppers, and the two inserting blocks on each stopper are respectively matched with one slot on each of the two adjacent stoppers.

[0010] Furthermore, the limiting member includes a limiting hole formed on the surface of the stopper and a limiting rod matched with the limiting hole. The limiting rod is detachably connected to the limiting hole, and when one end of the limiting rod matches with the limiting hole, the other end is inserted into the slope.

[0024] like Figure 1 to Figure 4 As shown,

[0025] A new type of ecological revetment is arranged on a bank slope 2 of a river channel 1, comprising a crushed stone layer 3 laid on the surface of the bank slope 2 and a plurality of concrete blocks 4 arranged on the upper surface of the crushed stone layer 3, wherein the crushed stone layer 3 is also mixed with mud and sand for filling the gaps between the crushed stones; the plurality of the blocks 4 are arranged in sequence along the length direction of the bank slope 2 at intervals, and are also arranged in sequence along the bank slope 2 toward the river channel 1, the plurality of the blocks 4 cooperate with each other and jointly cover the crushed stone layer 3, and any two adjacent blocks 4 are mutually plugged and jointly form a whole, and a limiting member 5 for horizontally limiting the block 4 is also provided between the block 4 and the bank slope 2, and each block 5 is provided with a limiting member 5 for horizontally limiting the block 4. The blocks 4 and the upper surface of the gravel layer 3 together form a storage chamber 6, and an opening connected to the storage chamber 6 is opened on the surface of each block 4, and soil is piled in each storage chamber 6, and plants 7 are planted in the soil. Different plants 7 can be planted according to the water level depth in the river channel 1. For example, submerged plants 7 are planted in the storage chamber 6 that is permanently located below the horizontal plane, and emergent plants 7 are planted in the storage chamber 6 close to the horizontal plane, etc. The types and growth positions of the plants 7 are reasonably planned, and the plants 7 grow outward through the opening; a retaining wall 8 for preventing the gravel layer 3 from sliding is vertically arranged between the bank slope 2 and the river channel 1.

[0026] As shown in the figure, the block 4 is made of prefabricated concrete, which effectively shortens the construction time of the ecological revetment; the multiple blocks 4 arranged on the bank slope 2 can effectively cover the gravel layer 3, protect the gravel layer 3 and the soil in the storage chamber 6 from being completely exposed to the outside and washed away by the water flow in the river channel 1, and since the multiple blocks 4 are arranged at intervals along the length direction of the bank slope 2, when the water flows through any two adjacent block blocks 4 arranged at intervals, the adjacent corners of the two blocks 4 can exert a certain resistance on the nearby water flow, slow down the flow rate of the water flow, and thereby reduce the speed of the water flow washing away the soil in the storage chamber 6, and the openings on the upper surfaces of the blocks 4 can also slow down the speed of the nearby water flow to a certain extent, and all the blocks 4 on the bank slope 2 cooperate with each other to effectively slow down The surrounding water flow speed provides a stable environment for the initial growth of plants 7; the block blocks 4 and the bank slope 2 are plugged into adjacent block blocks 4 along the river channel 1 to form a whole, and a limiter 5 is also provided between the block block 4 and the bank slope 2, so that the block block 4 can be firmly fixed in the current position for a long time, effectively resisting the continuous scouring of the water flow in the river, and can effectively resist the turbulent river even in the rainy season and other special circumstances, providing a stable environment for the growth of plants 7 and accumulated soil, and planting suitable plants 7 in the storage chambers 6 at different heights on the bank slope 2, ensuring the normal growth of plants 7, and allowing the roots of plants 7 to penetrate into the soil and gravel layer 3, thereby stabilizing the soil again and preventing soil loss.

[0027] In this embodiment, the cross section of the stopper 4 is “L”-shaped, and the longer side surface of the stopper 4 is horizontally arranged and inserted into the gravel layer 3 , and the other side surface is vertically arranged and plugged into the adjacent stopper 4 .

[0028] As shown in the figure, the "L"-shaped blocks 4 are stacked from the bank slope 2 toward the foot of the slope, and a larger storage chamber 6 is formed between the inner side of the block 4 and the upper surface of the gravel layer 3, which is convenient for piling up soil and planting plants 7. When the block 4 is installed, one end is inserted into the gravel layer 3 to maintain the current position. The gravel layer 3 provides effective support for the inserted part of the block 4. When all the blocks 4 are installed, there is a large area of ​​contact between the gravel layer 3 and each block 4, and they can form a whole, thereby improving the effect of the block 4 in resisting the scouring of river water. After multiple blocks 4 cooperate with each other and are installed, they can also form steps for citizens to step on and appreciate the ecological revetment and river water at close range, killing two birds with one stone.

[0029] In this embodiment, two slots 9 are provided on the horizontal surface of the block 4, and two plug-in blocks 10 cooperating with the slots 9 are provided on the vertical plane of the block 4. The plug-in blocks 10 are vertically arranged and detachably connected to the slots 9 on the surface of the adjacent block 4.

[0030] The insert block 10 cooperates with the slot 9 on the adjacent block 4 to limit the two blocks 4 in the horizontal direction, and the crushed stone layer 3 supports the two blocks 4 in the vertical direction, so that the two blocks 4 can be integrated into a whole, which is convenient for assembly and disassembly and construction.

[0031] In this embodiment, the blocks 4 arranged along the length direction of the bank slope 2 are staggered with the upper and lower adjacent blocks 4, and the two inserting blocks 10 on each block 4 are respectively matched with one slot 9 on each of the two adjacent block blocks 4 below.

[0032] Combination Figure 2 As shown, different blocks 4 are staggered in the direction from the bank slope 2 to the river channel 1, so that the two plug blocks 10 on the block 4 cooperate with the slots 9 on the corresponding two block blocks 4, and one block 4 can limit the other two blocks 4 through the cooperation of the slots 9 of the plug block 10, and the other two blocks 4 are also mutually restricted by the other blocks 4 through the cooperation of the slots 9 of the above-mentioned plug blocks 10, which can further improve the stability of a single plug block 10 and the integrity of a plurality of plug blocks 10 after combination, effectively resist the turbulent river, and provide a relatively stable environment for the soil and plants 7 in the storage chamber 6.

[0033] In this embodiment, the limiting member 5 includes a limiting hole 501 opened on the surface of the stopper 4 and a limiting rod 502 matched with the limiting hole 501. The limiting rod 502 is detachably connected to the limiting hole 501, and when one end of the limiting rod 502 matches with the limiting hole 501, the other end is inserted into the slope 2.

[0034] In order to further improve the stability of the block 4 on the gravel layer 3, the block 4 is restricted in the horizontal direction by a detachable connection between the limit rod 502 and the limit hole 501. The limit rod 502 can be cast by reinforced concrete. Since any two adjacent block 4 at different heights on the slope 2 form a whole after cooperating with each other through the slot 9 and the plug 10, it is not necessary to set a limit rod 502 on each block 4. According to the number and size of the block 4 set on the upper surface of the gravel layer 3, a suitable number of limit rods 502 are selected to cooperate with the corresponding limit holes 501, so that effective limitation of all the block 4 can be achieved, which not only improves the stability effect of the block 4, but also reduces the construction cost.

[0035] In this embodiment, a plurality of raised water-blocking blocks 11 are provided on a surface of each stopper 4 facing the river channel 1 and near the opening.

[0036] A plurality of raised water-blocking blocks 11 can further reduce the speed of the water flow around the block 4 and the opening, and while blocking the water flow, can also block the mud, sand and gravel carried in the water flow and make them accumulate around. Over time, the accumulated mud, sand and gravel will form a certain scale and will have a stabilizing effect on the block 4 and the plants 7 in the storage chamber 6; of course, the water-blocking blocks 11 can also have an anti-slip effect. When citizens walk on the block 4, the water-blocking blocks 11 can increase the friction between the surface of the block 4 and the sole of the shoe.

[0037] In this embodiment, a drainage ditch 12 is opened at the top of the bank slope 2. The drainage ditch 12 is arranged along the length direction of the bank slope 2, which can effectively intercept rainwater flowing from the top of the bank slope 2 toward the river, preventing rainwater from eroding and carrying away soil or plants 7.

[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
