Description

Technical Field

[0001] The present application relates to the technical field of river bank protection, and in particular to an interlocking vegetation retaining wall structure. Background Art

[0002] The main methods of river slope protection include natural slope protection, concrete slope protection, gabion slope protection, vegetation slope protection and geotextile slope protection. Among them, natural slope protection uses natural materials such as stones, wood, bamboo, etc. to construct natural river banks, imitate natural river landforms, and allow vegetation to grow naturally to achieve a protective effect. Natural slope protection has little impact on the environment, but requires long-term maintenance. Concrete slope protection uses concrete to cast the river bank, which can effectively prevent water erosion. Although concrete slope protection is strong and durable, it may have a certain impact on the ecological environment and is difficult to construct. Gabion slope protection will put stones into a cage woven with wire mesh to form a gabion bank protection. This has good anti-scouring ability and can provide growth space for plants, combining the advantages of engineering and ecology. However, the cost is high, the construction workload is large, and it is not suitable for sandy soil layers and rivers with more curved banks. Vegetation slope protection can be achieved by planting vegetation such as turf and trees on the bank slope, and using the mechanical and hydrological effects of plant roots to protect the slope and prevent soil erosion. However, in the early stages of plant growth, the protective ability is weak and it takes a long time to form a stable slope protection structure.

[0003] Therefore, river slope protection can be achieved by using concrete slope protection and vegetation slope protection. However, compared with the use of concrete slope protection alone, the combination of concrete slope protection and vegetation slope protection requires more construction steps, such as slope preparation, concrete construction, vegetation planting and maintenance management, which increases the difficulty and complexity of construction.

[0027] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0028] River slope protection generally uses cement blocks to cover the river slope. Although this method can prevent soil erosion to a certain extent, it hinders the exchange between water and soil, affects the self-purification ability of the river, and cannot give priority to ecology. In addition, most river slope protection structures are complex, the construction area is large, and the construction difficulty is high.

[0029] To solve the problem of high difficulty in river bank protection construction, see Figure 1-Figure 3 ,in, Figure 1 A schematic diagram of the interlocking vegetation retaining wall structure provided in an embodiment of the present application; Figure 2 A schematic diagram of a building block structure provided in an embodiment of the present application; Figure 3 This is a schematic diagram of the building block assembly structure provided in an embodiment of the present application.

[0030] The embodiment of the present application provides an interlocking vegetation retaining wall structure including: square piles 1, and a first cushion layer 2 is arranged at the connection between the square piles 1 and the ground; wherein the square piles 1 can provide physical support for the slope, prevent soil erosion and landslide, and maintain the stability of the slope. By arranging the square piles 1 in the slope, various forces from water flow or geological activities can be effectively resisted, thereby ensuring the safety and stability of both sides of the river. After the square piles 1 are driven at appropriate positions along the river bank, they are arranged around the square piles 1 by means of a cofferdam. At the connection between the square piles 1 and the ground, after the ground is leveled, a foundation pit is excavated and a first cushion layer 2 is arranged. The first cushion layer 2 is formed by tying steel bars and pouring concrete, which can improve the stability of the interlocking vegetation retaining wall structure. At the same time, since the water flow velocity at the bottom of the river channel is greater than the water flow velocity on the surface of the river channel, the concrete has a strong flood discharge and drainage function, so that the interlocking vegetation retaining wall structure can withstand a large water flow impact.

[0031] Among them, the cofferdam is a temporary enclosure structure. When constructing the interlocking vegetation retaining wall structure, the cofferdam can prevent water and soil from entering the construction location of the interlocking vegetation retaining wall structure, ensure that the construction area is dry, and facilitate drainage and excavation of the foundation pit. The height of the cofferdam is higher than the highest water level that may occur during the construction period to improve the safety of the construction.

[0032] The second cushion layer 3 connected to the first cushion layer 2; the second cushion layer 3 is arranged above the first cushion layer 2, and the second cushion layer 3 is rectangular as a whole. Figure 5 As shown, a stopper 301 is provided at one end of the second cushion layer 3 away from the first cushion layer 2, the stopper 301 protrudes from the surface of the second cushion layer 3, and the stopper 301 abuts against the building block 4. When the interlocking vegetation retaining wall structure is constructed, a stopper 301 is provided at one end of the second cushion layer 3, the stopper 301 protrudes from the surface of the second cushion layer 3 and is in close contact with the building block 4. When the height of the building block 4 increases, the lateral pressure of the building block 4 increases, and the building block 4 is easy to move away from the square pile 1, which will cause the interlocking vegetation retaining wall structure to collapse. Therefore, the stopper 301 is provided in the second cushion layer 3 to block the lateral pressure of the building block 4, enhance the lateral pressure of the building block 4 itself, and improve the safety of the interlocking vegetation retaining wall structure.

[0033] The blocks 4 arranged on the second cushion layer 3 are stacked in layers from bottom to top, any adjacent blocks 4 of the same layer abut against each other, and any two adjacent layers of blocks 4 interlock with each other; the distance from the block 4 to the second cushion layer 3 is inversely proportional to the distance from the block 4 to the square pile 1. Figure 3 As shown, Figure 3It is a schematic diagram of the combined structure of blocks 4, wherein, for the sake of ease of introduction, the blocks 4 in contact with the second cushion layer 3 are set as the first layer. A boss 404 is provided at one end of the blocks 4 close to the square pile 1, and the blocks 4 are engaged with each other through the boss 404. The end of the boss 404 of the first layer of blocks 4 away from the blocks 4 abuts against the second cushion layer 3. After the first layer of blocks 4 is laid, the second layer of blocks 4 is stacked on the first layer of blocks 4, and the end of the boss 404 of the second layer of blocks 4 away from the blocks 4 is engaged with the boss 404 of the first layer of blocks 4. The adjacent two layers of blocks 4 are engaged with each other through the boss 404, which increases the interlocking property between the blocks 4 and improves the structural stability. Reduce the displacement of the blocks 4 due to water flow impact.

[0034] At the same time, if Figure 1 As shown, since the boss 404 protrudes from the surface of the building block 4, there is an angle between the first layer of building blocks 4 and the second cushion layer 3. When the building blocks 4 are stacked and the number of layers of building blocks 4 continues to increase, the building blocks 4 will gradually approach the square piles 1, and finally the building blocks 4 will abut against the square piles 1.

[0035] When laying the blocks 4, a gravel layer 6 can be set between the blocks 4 and the square piles 1. For example, after the first layer of blocks 4 is laid, a gravel layer 6 can be laid between the first layer of blocks 4 and the square piles 1, and the height of the gravel layer 6 is not higher than the height of the first layer of blocks 4. After the second layer of blocks 4 is laid, a gravel layer 6 can be laid again between the second layer of blocks 4 and the square piles 1, and the height of the gravel layer 6 laid each time is not higher than the height of the top layer of blocks 4. The blocks 4 and gravel are laid in sequence, and finally the interlocking vegetation retaining wall structure is completed. The laying of the gravel layer 6 can provide support for the blocks 4, reducing the occurrence of damage to the blocks 4 due to large forces. At the same time, the blocks 4 can provide protection for the gravel layer 6, reducing the loss of gravel due to water erosion of the gravel layer 6.

[0036] In addition, if Figure 4 As shown, when the river channel is in an arc shape, the placement position of the building blocks 4 can be set to realize the construction of an interlocking vegetation retaining wall structure for the arc-shaped river channel. Therefore, by setting the square piles 1 and the building blocks 4, the interlocking vegetation retaining wall structure can be constructed for a river channel with a complex shape, so as to solve the problem of high difficulty in the construction of the river channel slope protection project in an uneven river channel.

[0037] In some embodiments, the blocks 4 of two adjacent layers further include anchor rods 8, and the blocks 4 are provided with anchor holes 403. The anchor rods 8 are inserted into the anchor holes 403 to connect any two adjacent layers of blocks 4. In the construction of interlocking vegetation retaining wall structure engineering, blocks 4 with anchor holes 403 are stacked to form a wall, and any two adjacent layers of blocks 4 are firmly connected together by inserting the anchor rods 8 into these anchor holes 403. The stability and integrity of the interlocking vegetation structure are improved. The blocks 4 are prevented from shifting due to external forces.

[0038] In some embodiments, the interlocking vegetation retaining wall structure further includes a geotextile 8, which is arranged between the gravel layer 6 and the square piles 1. For example, after the square piles 1 are arranged, they can be arranged in sections between any two adjacent square piles 1, and the geotextile 8 can be used to block all the square piles 1, so as to reduce the loss of fine particles when the gravel layer 6 is laid, protect the structure of the gravel layer 6, and disperse the load and reduce the pressure on the square piles 1.

[0039] In some embodiments, Figure 6 As shown, the interlocking vegetation retaining wall structure also includes a capping 9, which is arranged at the end of the square pile 1 away from the first cushion layer 2, and the capping 9 abuts against the building block 4. In the construction of the interlocking vegetation retaining wall structure, in order to protect the edge of the river channel, a capping 9 is arranged at the end of the square pile 1 away from the first cushion layer 2, and the capping 9 is in close contact with the building block 4, thereby strengthening the supporting force of the edge of the river channel and preventing collapse. In addition, by arranging the capping 9, a neat edge is provided for the river channel.

[0040] In some embodiments, Figure 2 As shown, the block 4 includes a first hole 401 and a second hole 402, wherein the first hole 401 has a rectangular cross section and the second hole 402 has a hexagonal cross section. The first hole 401 can be used to fill pebbles, and the second hole 402 can be used to plant aquatic plants. For example, after each layer of the block 4 is laid, pebbles can be placed in the first hole 401. By filling the first hole 401 with pebbles, the overall shear strength of the block 4 can be improved.

[0041] At the same time, after the laying of the blocks 4 and the gravel layer 6 is completed, aquatic plants can be planted in the second hole 402. The aquatic plants planted are mainly to maintain the stability of the interlocking vegetation retaining wall structure, enhance biodiversity and beautify the environment. Specifically, the root system of aquatic plants can effectively fix the soil, reduce the scouring and erosion of the river bank by water flow, and improve the stability of the interlocking vegetation retaining wall structure. Aquatic plants also help to restore and enhance the diversity of the riverbank ecosystem, provide habitats for various organisms, and maintain ecological balance. In addition, aquatic vegetation can enhance the river landscape, increase leisure and ornamental value, and improve the living environment of surrounding residents.

[0042] In some embodiments, the second cushion layer 3 includes a rebar 5, which is connected to the square pile 1, and the second cushion layer 3 is cast by the rebar 5. During construction, the second cushion layer 3 is implanted with steel bars and connected to the square pile 1, and then the cushion layer is made into a whole by pouring concrete. For example, the second cushion layer 3 can be formed by tying the foundation steel bars and pouring the layer, and a section of steel bars is reserved on the side where the second cushion layer 3 is connected to the square pile 1, and then the contact point between the square pile 1 and the reserved steel bars of the second cushion layer 3 is set as a positioning point, and a hole is drilled at the positioning point of the square pile 1, and the hole diameter and depth must meet the design requirements to ensure that the steel bars can be firmly implanted. After the drilling is completed, it is necessary to remove the dust and impurities in the hole, inject the special structural adhesive into the clean hole, and then remove the rust and clean the steel bars to ensure a good combination of the steel bars and the structural adhesive. Slowly screw the treated steel bars into the hole that has been injected with the structural adhesive according to the design requirements, and ensure that the steel bars reach the predetermined position. Finally, quality inspection is carried out, including pull-out test, etc., to ensure that the quality of the rebar 5 work meets the design and safety requirements.

[0043] The second cushion layer 3 is connected to the square piles 1 by planting reinforcement 5, so that the bonding strength between the second cushion layer 3 and the square piles 1 can be improved, and the durability and crack resistance of the interlocking vegetation retaining wall structure are improved.

[0044] In some embodiments, the distance between the centers of any two adjacent square piles 1 is 50-60 cm. In the construction of the interlocking vegetation retaining wall structure, the center distance between any two adjacent square piles 1 is set to 50-60 cm, ensuring that there is sufficient support distance between the square piles 1 to prevent ground settlement, so as to ensure sufficient bearing capacity and stability of the interlocking vegetation retaining wall structure.

[0045] It can be seen from the above technical scheme that the present application provides an interlocking vegetation retaining wall structure, including: square piles 1, a first cushion layer 2 is provided at the connection between the square piles 1 and the ground; a second cushion layer 3 connected to the first cushion layer 2; blocks 4 provided on the second cushion layer 3, blocks 4 are stacked in layers from bottom to top, any adjacent blocks 4 of the same layer are abutted, and any two adjacent layers of blocks 4 are interlocked; the distance from the blocks 4 to the second cushion layer 3 is inversely proportional to the distance from the blocks 4 to the square piles 1; and a gravel layer 6 is provided between the blocks 4 and the square piles 1. The square piles 1 are embedded in the target land, and a whole is formed by providing the first cushion layer 2, the second cushion layer 3 and the square piles 1, the blocks 4 are staggered and stacked on the second cushion layer 3, and the gaps between the blocks 4 and the square piles 1 are filled with the gravel layer 6 to complete the establishment of an interlocking vegetation retaining wall structure, reduce the construction scope, and solve the problem of high difficulty in river bank protection construction.
