Description

Technical Field

[0001] The present invention relates to the field of slope construction, and more particularly to a method for reinforcing a coastal roadbed slope by utilizing salt-tolerant plants and a construction method thereof. Background Art

[0002] Coastal roadbed slopes refer to the slopes on both sides of roads built in coastal areas. They not only bear the effects of their own gravity and vehicle loads, but also have to resist erosion from multiple external forces such as sea breeze, sea water, and waves. These external forces can cause salinization of the slope soil, that is, the soil contains excessive soluble salts, which reduces the strength and stability of the soil and increases the risk of slope instability and landslides. Therefore, the reinforcement of coastal roadbed slopes is an important measure to ensure safe road operation and prevent environmental damage.

[0003] At present, the reinforcement of coastal salinized slopes at home and abroad basically adopts concrete or anchor reinforcement, that is, laying concrete on the slope surface or setting anchors inside the slope to improve the shear strength and stability of the slope. Although these methods have certain effects, they also have some disadvantages.

[0004] First, concrete or anchor reinforcement increases the construction and maintenance costs of roadbed projects, especially in coastal areas, where concrete or anchors are easily corroded by salt and fail. Second, concrete or anchor reinforcement destroys the original ecosystem and landscape of the slopes, which is detrimental to ecological protection and tourism development in coastal areas. Finally, concrete or anchor reinforcement does not improve the quality and performance of the salinized soil itself, but only hardens the surface or interior.

[0005] Therefore, it is necessary to propose a new type of coastal roadbed slope that uses plants to improve soil salinization and reinforce slopes. Summary of the Invention

[0006] 1. Technical problems to be solved

[0007] In response to the problems existing in the prior art, the purpose of the present invention is to provide a method for reinforcing coastal roadbed slopes using salt-tolerant plants, which can improve soil strength and stability, prevent soil erosion, and buffer external force impacts.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] Example 1:

[0037] See also Figure 1-7 A method for reinforcing a coastal roadbed slope using salt-tolerant plants includes a slope 1, a mounting base 2 is provided on the top of the slope 1, a base plate 3 is provided on the inner side of the mounting base 2, a plurality of water-blocking structures are installed on the top of the base plate 3, and the water-blocking structures are used to prevent water loss. A vegetation plate 4 is provided on the top of the base plate 3 and on the top of the water-blocking structure, a plurality of mounting racks 5 are installed on the top of the vegetation plate 4, and a plurality of slopes 20 are provided on the outer sides of the mounting racks 5. The arrangement of the slopes 20 makes it easy for water to flow down along the slopes 20 when it impacts the plants. A vegetation trough 6 is provided at the center of the mounting frame 5. The base plate 3 is installed on the top of the slope 1, and a water-blocking structure is provided on it. Plants with strong salt tolerance are planted on the inner side of the mounting frame 5 and the vegetation trough 6 to allow them to take root and sprout. Their roots penetrate deep into the space between the vegetation plate 4 and the base plate 3 to absorb nutrients and salt to decompose it, thereby reducing soil salinization. When selecting plants, salt-tolerant plants such as perennial shrub-type forage grasses or productive crops can be selected. It should be noted that when selecting plants, vegetation with a well-developed root system needs to be selected.

[0038] See Figure 3The water-blocking structure includes a central annular block 7, which is mounted on the top of the base plate 3. A plurality of connecting plates 8 are fixed to the outside of the central annular block 7. A water-blocking expansion plate 9 is fixed to the side of the connecting plate 8 away from the central annular block 7. When there is too much seawater on the slope 1, the water-blocking expansion plate 9 is set so that the water-blocking expansion plate 9 can absorb water and expand, thereby enabling the water-blocking expansion plate 9 to block moisture, thereby ensuring the absorption of salt by plants and reducing water and soil loss. By setting up a plurality of water-blocking expansion plates 9, the water-blocking effect is better, and a certain gap is left between each two adjacent water-blocking expansion plates 9, so that the expanded water-blocking expansion plates 9 will not block each other.

[0039] A fertilizer supply and desalination structure is installed on the inner side of the central annular block 7, which is used to desalinate plants and provide fertilizer.

[0040] See Figure 4 , a plurality of connecting water pipes 10 are provided on the inner side of the water-blocking expansion plate 9, and a transfer bin 11 is provided at the center of the plurality of connecting water pipes 10 and on the inner side of the water-blocking expansion plate 9. The transfer bin 11 is used to transfer water, and a plurality of thin tubes 12 are provided on the outer side of each connecting water pipe 10, and the ends of the thin tubes 12 away from the connecting water pipes 10 are connected to the outer side of the water-blocking expansion plate 9. Through the setting of the connecting water pipes 10, the connecting water pipes 10 can pass water, and then the water can flow out of the water-blocking expansion plate 9, thereby Avoid excessive accumulation of water on the water-blocking expansion plate 9, avoid flooding of plants, etc., so that the water-blocking expansion plate 9 can block water and soil, prevent its loss, and will not block it too severely, thereby ensuring the protection effect of plants. In the process of water flow, it is guided by the capillary 12 and the connecting water pipe 10, and the water is allowed to circle around the inner side of the water-blocking expansion plate 9 for a long enough time, and is transferred through the transfer bin 11 to guide the water for a second time, so that the water can flow out of the inner side of the water-blocking expansion plate 9.

[0041] See Figure 5 The fertilizer supply and desalination structure includes a mounting column 14, which is fixed at the center of the central annular block 7. A mounting chamber 18 is provided on the inner side of the mounting column 14. A resistance piece 16 is slidably connected to the inner side of the mounting chamber 18. A decomposition and fertilization strip 15 is provided on the top of the resistance piece 16. The decomposition and fertilization strip 15 is composed of a desalting material and a fertilizer supply. The desalting part is mainly composed of soil and microorganisms. The microorganism can be one or a concentrated combination of green algae, nitrifying bacteria, urea phosphate or other microorganisms capable of decomposing salt. The equation can be:

[0042] (NH2)2CO+2H2O→2NH4 + +CO2

[0043] Nitrogen dioxide + O2 + H2O → nitrogen trioxide + 2H +

[0044] NH3+2O2→NO2-+2H++H2O

[0045] One or more of the above.

[0046] A first spring 17 is installed on the inner side of the mounting bin 18 and between the mounting post 14 and the contact piece 16. At least one dispersion groove 19 is provided on the outer side of the mounting post 14 and near the top of the mounting post 14. When the plant grows, some mounting posts 14 can be pre-buried. Through the setting of the first spring 17, the first spring 17 pushes the contact piece 16 and the decomposition and fertilization strip 15, so that the decomposition and fertilization strip 15 is always in contact with the dispersion groove 19. Through the migration of water and soil and the flow of water, a part of the decomposition and fertilization strip 15 is brought out, thereby making the decomposition and fertilization strip 15 The decomposition fertilization strip 15 can fertilize the plants, and the desalination part inside the decomposition fertilization strip 15 can also decompose the salt to prevent the death of plants due to excessive salt, thereby further reducing the salinization of the soil. Due to geological activities and the setting of the water-blocking expansion plate 9, the flow of water is relatively slow, thereby ensuring that the decomposition fertilization strip 15 also evaporates slowly, and can ensure a usable period of ten to fifteen years. If the decomposition fertilization strip 15 is withdrawn and used up, the desalination part inside it can grow in the soil to ensure desalination of the soil.

[0047] See Figure 7, a connecting column 21 is further provided on the inner side of the mounting frame 5 and on one side of the vegetation trough 6, a connecting bottom column 27 is extended from the bottom of the connecting column 21, and the connecting bottom column 27 and the inner side of the connecting column 21 jointly construct a fertilizer bin 26, and the stirring assembly includes a rotating stirring column 22, and the rotating stirring column 22 is fixed at the center position of the top of the blocking rubber plate 25, and a plurality of rotating stirring plates 23 are provided on the outer side of the rotating stirring column 22. Through this arrangement, when it is necessary to stir the fertilizer liquid, the rotating stirring column 22 can be rotated, and then the rotating stirring plate 23 is driven to rotate by the rotating stirring column 22, so that the fertilizer liquid is mixed and stirred by the rotating stirring plate 23, and a feeding trough 24 is provided on the top of the connecting column 21, and the feeding trough 24 is inclined toward the inner side of the fertilizer bin 26, and the feeding The setting of the groove 24 allows the user to add some fertilizer liquid to the inner side of the fertilizer bin 26 through the feeding groove 24. The inner side of the fertilizer bin 26 is slidably connected to a blocking rubber plate 25, and a sealing slide 28 is fixed to the bottom of the blocking rubber plate 25. A second spring 29 is provided on the inner side of the sealing slide 28 and between the connecting bottom column 27 and the blocking rubber plate 25. At least one flow hole 13 is provided on the outer side of the connecting column 21 and at a position corresponding to the blocking rubber plate 25. When the plants need to be fertilized for the second time, the fertilizer liquid can be added to the inner side of the connecting column 21. After sufficient stirring, the stirring column 22 is pulled and rotated, thereby driving the blocking rubber plate 25 to move upward, thereby exposing the flow hole 13, and the fertilizer can flow to the roots of the plants through the flow hole 13 to fertilize the plants.

[0048] A stirring assembly is also provided on the top of the blocking rubber plate 25 .

[0049] Example 2:

[0050] A construction method for reinforcing coastal roadbed slopes using salt-tolerant plants is applied to the above-mentioned method for reinforcing coastal roadbed slopes using salt-tolerant plants, and includes the following steps:

[0051] The first step is to plant plants with strong salt tolerance inside the mounting frame 5 and the vegetation trough 6, so that they take root and sprout. The roots penetrate deep into the space between the vegetation plate 4 and the base plate 3, absorb nutrients, and absorb salt to decompose it, thereby reducing soil salinization. When selecting plants, salt-tolerant plants such as perennial shrubs or productive crops can be selected.

[0052] Step 2: By setting the water-blocking expansion plate 9, the water-blocking expansion plate 9 can absorb water and expand, thereby enabling the water-blocking expansion plate 9 to block moisture, thereby ensuring the absorption of salt by plants and reducing water and soil loss. By setting multiple water-blocking expansion plates 9, the water-blocking effect is improved, and a certain gap is left between each two adjacent water-blocking expansion plates 9, so that the expanded water-blocking expansion plates 9 will not block each other.

[0053] The third step: through the setting of the connecting water pipe 10, the connecting water pipe 10 can pass water, and then the water can flow out from the water-blocking expansion plate 9, so as to avoid the water-blocking expansion plate 9 from accumulating too much water, and avoid the phenomenon of flooding the plants;

[0054] The fourth step: through the setting of the first spring 17, the first spring 17 pushes the contact piece 16 and the decomposed fertilizer strip 15, so that the decomposed fertilizer strip 15 is always in contact with the dispersion groove 19. Through the migration of water and soil and the flow of water, a part of the decomposed fertilizer strip 15 is taken out, so that the decomposed fertilizer strip 15 can fertilize the plants, and the salt in the decomposed fertilizer strip 15 can also be decomposed, so as to prevent the salt from being too large to cause the plants to die, thereby further reducing the salinization of the soil;

[0055] The fifth step: when the plants need to be fertilized again, the fertilizer liquid can be added to the inside of the connecting column 21. After sufficient stirring, the rotating stirring column 22 is pulled, and then the blocking rubber plate 25 is driven to move upwards, so that the flowing hole 13 is exposed, and the fertilizer can flow to the roots of the plants through the flowing hole 13 to fertilize the plants.

[0056] The above is only the preferred specific implementation of the present application; however, the protection scope of the present application is not limited to this. Any person skilled in the art, according to the technical solution and the improvement concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
