[0027] In the implementation process, it is worth noting that the pole body 1 is usually made of high-strength steel to ensure that it can withstand various external forces without deformation or damage during long-term use. The slope cylinder 3 is made of engineering plastic or metal material, and its size is customized according to the specifications of the pole body 1 and the actual situation of the slope 2 to ensure its sufficient strength and durability. A portion of the first bolt 5 penetrates through the aligned lugs 4, and the first bolt 5 penetrates through the aligned lugs 4 and is partially threaded with a nut 6. The nut 6 is tightly abutted with the lug 4, and a pair of slope cylinders 3 can be installed on the pole body 1. The material of the inner lining layer 7 can be rubber or other elastic materials, which can increase the friction between the slope cylinder 3 and the pole body 1, prevent the slope cylinder 3 from sliding on the pole body 1, and also have a certain buffering effect, reducing the wear between the pole body 1 and the slope cylinder 3. The materials of the semicircular ring 9 and the semicircular disc 11 should also have sufficient strength, and the same material as the slope cylinder 3 should be selected to ensure the stability of the entire stability assembly. The type of vegetation 13 is not limited and can be determined according to the geographical environment of the installation area. The vegetation 13 needs to have sufficient vitality.

[0028] Further, a plurality of insertion rods 14 are inserted into the top end of the slope cylinder 3.

The top end of the insertion rod 14 is fixedly connected with a top block 15, and the top block 15 is in close contact with the top end of the slope cylinder 3.

[0029] In the implementation process, it is worth noting that the material of the insertion rod 14 is hard metal, such as stainless steel. The length and diameter of the insertion rod 14 should be reasonably designed according to the soil condition of the slope 2 and the required stability level. After the insertion rod 14 is inserted into the interior of the slope 2, the connection strength between the slope cylinder 3 and the slope 2 can be increased. The shape of the top block 15 can be circular or square, which facilitates the insertion of the insertion rod 14 into the ground.

[0030] Further, the inner wall of the through hole 8 is fixedly connected with a support rod frame 16.

[0031] In the implementation process, it is worth noting that the support rod frame 16 is usually formed by cross-welding metal rods to form a stable frame structure. Its function is to block and disperse rainwater when it passes through the through hole 8, avoiding concentrated rainwater from eroding a certain part of the slope 2. At the same time, it can also enhance the structural strength of the through hole 8 to prevent deformation or damage of the through hole 8 when subjected to external forces. The grid size of the support rod frame 16 should be designed according to actual needs to ensure that rainwater can pass smoothly and effectively block and disperse.

[0032] Further, a plurality of protruding rods 17 are fixedly connected to the portion of the outer wall of the slope cylinder 3 located inside the slope 2.

[0033] In the implementation process, it is worth noting that the material of the convex rod 17 is the same as that of the slope cylinder 3, the convex rod 17 increases the friction and engagement force between the slope cylinder 3 and the soil of the slope 2, so that the slope cylinder 3 can be better fixed in the slope 2, and the length and diameter of the convex rod 17 should be reasonably selected according to the soil quality of the slope 2. For the slope 2 with relatively soft soil, the convex rod 17 should be appropriately lengthened and thickened to enhance its fixing effect, and the distribution of the convex rod 17 on the outer wall of the slope cylinder 3 should be uniform to ensure that the slope cylinder 3 can receive sufficient fixing force in all directions.

[0034] Further, the inner lining layer 7 is provided with a plurality of micropores 18.

[0035] In the implementation process, it is worth noting that the micropores 18 can improve the flexibility of the inner lining layer 7.

[0036] Further, the first bolt 5 and the nut 6 are sleeved with a first protective cylinder 19, the first protective cylinder 19 is threadedly connected with the lug 4 through a first threaded groove 20, the first threaded groove 20 is formed on the surface of the lug 4, the outer wall of the first protective cylinder 19 is fixedly installed with a first sleeve ring 21, the first sleeve ring 21 is fixedly connected with a first soft ring 22 close to the surface of the lug 4, the first soft ring 22 abuts against the lug 4, the second bolt 10 is sleeved with a second protective cylinder 23, the second protective cylinder 23 is threadedly connected with the semicircular ring 9 through a second threaded groove 24, the second threaded groove 24 is formed on the surface of the semicircular ring 9, the outer wall of the second protective cylinder 23 is fixedly installed with a second sleeve ring 25, the second sleeve ring 25 is fixedly connected with a second soft ring 26 close to the surface of the semicircular ring 9, and the second soft ring 26 abuts against the semicircular ring 9.

[0037] In the implementation process, it is worth noting that the material of the first protective cylinder 19 and the second protective cylinder 23 is usually plastic or metal material with good corrosion resistance, the specifications of the first threaded groove 20 and the second threaded groove 24 should match the threads of the first protective cylinder 19 and the second protective cylinder 23 to ensure the firmness of the connection, the first sleeve ring 21 and the second sleeve ring 25 can fix the first soft ring 22 and the second soft ring 26, and can also enhance the connection strength between the first protective cylinder 19 and the second protective cylinder 23 and the lug 4 and the semicircular ring 9, the material of the first soft ring 22 and the second soft ring 26 can be rubber or other elastic materials, which can fill the gap between the first protective cylinder 19, the second protective cylinder 23 and the lug 4 and the semicircular ring 9, play a sealing and buffering role, prevent water, oxygen and corrosive substances from entering, and thus protect the first bolt 5, the second bolt 10 and the nut 6 from corrosion.

[0038] Working principle:

[0039] Foundation installation and slope fixing principle:

[0040] First, a pit for pre-embedded rod body 1 is opened on the surface of slope 2. After the rod body 1 is erected and placed, the slope cylinder 3 is fitted on both sides. The through hole 8 on the surface of the slope cylinder 3 is inclined, and the inclination angle of the through hole 8 is the same as the inclination angle of the slope 2. Then, the first bolt 5 is inserted through the two aligned lugs 4, and the nut 6 is tightened to complete the installation of the slope cylinder 3 and the rod body 1. Then, fill the pit and tamp it, insert the rod 14 into the slope 2, make the top block 15 fit with the top end of the slope cylinder 3, then use the second bolt 10 to install the semicircular ring 9 and the semicircular disc 11 on the outer wall of the slope cylinder 3, and then plant the vegetation 13 in the slope 2 through the vertical hole 12. With the passage of time, the stems of the vegetation 13 extend to the slope 2, forming a stable whole with the semicircular disc 11, semicircular ring 9, slope cylinder 3 and rod body 1, greatly improving the overall stability and effectively preventing the impact of slope sliding on the foundation of the power transmission line tower.

[0041] Rainwater diversion and shear strengthening principle:

[0042] When encountering heavy rainfall, rainwater flows down from the high part of the slope 2 and rushes towards the slope cylinder 3. At this time, part of the rainwater will pass through the slope cylinder 3 through the through hole 8 on the surface of the slope cylinder 3, changing the traditional flow path of the rainwater. This design can slow down the increase in water content of the slope 2, avoid the decrease in soil shear strength caused by excessive water accumulation, and maintain the mechanical properties of the soil by reasonably guiding the flow of rainwater, reducing the direct erosion and soaking of rainwater on the slope soil, providing more reliable stability protection effect for the foundation of the power transmission line tower, and ensuring the stability of the tower foundation in bad weather conditions.

[0043] Bolt protection and durability improvement principle:

[0044] After the assembly is completed, in order to ensure the long-term stability of the connected parts, the user will fit the first protective cylinder 19 on the outside of the first bolt 5 and the nut 6, and threadedly connect it with the first threaded groove 20, so that the first soft ring 22 is in a tight state. At the same time, the second protective cylinder 23 is fitted on the outside of the second bolt 10, and is threadedly connected with the second threaded groove 24, so that the second soft ring 26 is in a tight state. The first protective cylinder 19 and the second protective cylinder 23 can effectively isolate moisture, oxygen and corrosive substances in the external environment, greatly reducing the probability of rust and strength reduction of the first bolt 5, the second bolt 10 and the nut 6. This not only facilitates the stable installation and connection between the structural parts, but also improves the durability of the entire slope protection device, ensuring that the rod body 1 can be set up stably for a long time, and providing continuous and reliable support for the foundation of the power transmission line tower.

[0045] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
