Description

Technical Field

[0001] This application relates to the technical field of mountain afforestation, and in particular to a mountain afforestation slope and its construction technology. Background Technology

[0002] Afforestation in mountainous areas refers to the process of creating or restoring forests, trees, and shrublands on mountains or barren hills through artificial means. In various parts of my country, soil erosion in barren hills is a serious problem, especially in remote areas of the northwest. Therefore, afforestation in mountainous areas is of great significance.

[0003] Related technologies for afforestation in mountainous areas include plastic bag seedling cultivation, where seedlings are transplanted into plastic bags filled with nutrient soil. Then, at a designated location, the hillside is cleared and broken up, and a tree basin is constructed using grass roots and gravel. A planting pit is dug in the center of the basin, and the excavated soil is used to fill the basin. The pit is then backfilled with well-rotted topsoil and compacted, ensuring the base of the seedling in the nutrient bag is 2cm below the ground surface. Two inverted V-shaped irrigation ditches are dug above the tree basin to retain water and irrigate the plants.

[0004] In the aforementioned technologies, during the growth process of seedlings, when exposed to external influences such as strong winds, the seedlings are prone to tilting, which affects plant growth. Summary of the Invention

[0005] To facilitate plant growth, this application provides a mountain afforestation slope and its construction technology.

[0006] Firstly, this application provides a mountain afforestation slope.

[0007] The following technical solution is adopted:

[0008] A mountain afforestation slope includes a planting area on the mountain slope for planting trees. A water-retaining plate is provided on the side of the mountain slope near the bottom. A support device is provided on the mountain slope. The support device includes a mounting sleeve and a support rod. The mounting sleeve is fitted over the outside of the tree. Multiple support rods are arranged around the mounting sleeve. One end of the support rod is connected to the mounting sleeve, and the other end abuts against the mountain slope to support the tree.

[0009] By adopting the above technical solutions, water-blocking plates are installed to reduce soil erosion, while support rods and mounting sleeves are installed to support the trees and reduce the tendency of the trees to tilt, so as to promote plant growth.

[0010] Optionally, an installation block is provided on the outer side of the installation sleeve. A groove is formed on the installation block in the vertical direction. The support rod includes a vertical part and a support part. The vertical part is slidably arranged in the groove in the vertical direction. The support part and the vertical part are connected. The end of the support part away from the vertical part abuts against the mountain slope. The end of the support part near the mountain slope is inclined in the direction away from the trees to support the trees. A fixing component for fixing the vertical part is provided on the installation block.

[0011] By adopting the above technical solution, the vertical part is set to slide in the groove. When supporting the tree, the position of the vertical part in the groove is adjusted, thereby adjusting the contact between the support part and the ground. Then, it is fixed by the fixing component. By setting multiple vertical parts to slide in the groove, the support height without passing through the support part can be adjusted, so as to support the tree on the inclined surface or uneven surface, thereby improving the support effect.

[0012] Optionally, the vertical portion and the mounting sleeve are spaced apart, and multiple mounting blocks and multiple support rods are correspondingly provided. The fixing component includes a fixing sleeve, a fixing block, and a fixing pin. The fixing sleeve is sleeved on the outside of multiple mounting blocks and is rotatably disposed outside the mounting blocks. The fixing block is disposed inside the fixing sleeve, with one end of the fixing block facing away from the fixing sleeve spaced apart from the fixing sleeve. The side of the fixing block near the fixing sleeve abuts against the vertical portion to fix the vertical portion. A through hole is provided on the side of the fixing sleeve, and the fixing pin is inserted into the through hole. The fixing pin abuts against the side of the vertical portion facing away from the fixing block to fix the fixing sleeve.

[0013] By adopting the above technical solution, after the fixed sleeve rotates and drives the fixed block to abut against the vertical part, the fixing pin is inserted into the through hole. The fixing pin abuts against the side of the vertical part, reducing the phenomenon of reverse rotation of the fixed sleeve, and supporting and fixing the vertical part and the support part.

[0014] Optionally, the mounting sleeve has a mounting groove in its side wall, and a snap-fit ​​rod is provided on the inner side of the mounting sleeve. The snap-fit ​​rod extends through the mounting sleeve into the mounting groove and slides on the mounting sleeve in a direction toward the center of the mounting sleeve. A snap-fit ​​sleeve is provided on the side of the snap-fit ​​rod near the inside of the mounting sleeve. A linkage block is slidably provided in the mounting groove, and a guide slope is provided on the side of the linkage block. The guide slope abuts against the end of the snap-fit ​​rod, and the movement of the linkage block causes different positions on the guide slope to abut against and move the snap-fit ​​sleeve.

[0015] By adopting the above technical solution, the moving linkage rod drives the locking rod to move through the linkage block, which in turn drives the locking sleeve to move in the direction toward the tree until the locking sleeve and the tree come into contact, thereby pre-fixing the installation sleeve so as to fix the support rod.

[0016] Optionally, the linkage block is slidably disposed within the mounting groove around the center of the mounting sleeve. A linkage rod is disposed on the linkage block, extending to the outside of the mounting groove. A push rod is disposed on the fixed sleeve, the push rod being disposed along the direction of the center of the mounting sleeve. The push rod rotates with the fixed sleeve until it abuts against the linkage rod, causing the linkage rod to rotate.

[0017] By adopting the above technical solution, when the fixed sleeve is rotated, the fixed sleeve drives the push rod to rotate, and the rotation of the push rod drives the linkage rod to rotate, thereby realizing the movement of the snap-fit ​​sleeve while fixing the vertical part, thus improving the installation efficiency.

[0018] Optionally, at least multiple sets of the snap-fit ​​sleeve and linkage rod are provided, with the multiple sets of the snap-fit ​​sleeve and linkage rod arranged around the center of the mounting sleeve, and multiple push rods and multiple sets of linkage rods are correspondingly provided.

[0019] By adopting the above technical solution, multiple snap-fit ​​sleeves are set up to cooperate with the trees, thereby improving the stability of the cooperation between the installation sleeve and the trees.

[0020] Optionally, the mounting sleeve includes two semi-circular mounting portions, one end of the two mounting portions is rotatably connected, and the other end is fixed by bolts. The fixing sleeve includes two semi-circular fixing portions, and the two fixing portions are connected by bolts.

[0021] By adopting the above technical solution, the mounting sleeve and fixing sleeve can be installed on the outside of the tree.

[0022] Optionally, multiple fixing blocks are provided, and each fixing block and a vertical part are provided in a one-to-one correspondence.

[0023] By adopting the above technical solution and setting multiple fixing blocks, the positions of multiple vertical parts can be fixed simultaneously, thereby further improving installation efficiency.

[0024] Optionally, the side of the fixing block facing away from the fixing sleeve is provided in a pointed shape.

[0025] By adopting the above technical solution, a pointed shape is provided so that when the fixed sleeve drives the fixed block to rotate, the pointed part drives the fixed block to move to the other side of the vertical part and cooperate with the vertical part, which facilitates the fixation of the vertical part.

[0026] Secondly, this application provides a construction technique for afforestation slopes in mountainous areas.

[0027] The following technical solution is adopted:

[0028] A construction technique for afforestation slopes in mountainous areas, employing the aforementioned afforestation slope method, includes the following steps:

[0029] Planting trenches are dug in the planting area, and trees are planted in the planting trenches;

[0030] The baffle was buried on the side of the planting area near the bottom of the slope;

[0031] The installation sleeve is placed on the outside of the tree and then fixed with bolts. Then, the linkage rod is manually rotated to make the snap-fit ​​sleeve abut against the side of the tree to pre-fix the installation sleeve.

[0032] The retaining sleeve is installed on the outside of the mounting block using bolts;

[0033] Adjust the position of each vertical part so that the ends of each support part are placed on the ground;

[0034] Rotate the fixing sleeve, and the fixing sleeve will drive the fixing block to move until it abuts against the vertical part, clamping the vertical part between the fixing part and the fixing block, thus fixing the vertical part and the support part.

[0035] When the fixing block is fully rotated to engage with the vertical part, the push rod rotates to abut against the linkage rod, causing the snap-fit ​​sleeve to move. The fixing block and the vertical part are fully engaged, and the snap-fit ​​sleeve clamps the tree, thus fixing the position of the mounting sleeve and support rod.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. By installing mounting sleeves and support rods on the sides of the trees, the trees are supported, reducing the tendency for them to tilt during growth and promoting healthy growth. Attached Figure Description

[0045] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0046] This application discloses a type of afforestation slope in mountainous areas.

[0047] Reference Figure 1 and Figure 2 The afforestation slope includes a planting area 11 established on the mountain slope 1, in which trees 2 are planted. A water-retaining plate 12 is installed on the side of the planting area 11 closest to the ground. The water-retaining plate 12 is inserted into the ground and spaced apart from the trees 2. The water-retaining plate 12 is used to prevent water and soil erosion, thereby promoting the growth of the trees 2.

[0048] Reference Figure 2 and Figure 3 A support device 3 is also installed on the hillside 1 to support the trees 2. The support device 3 includes a mounting sleeve 31 and support rods 32. The mounting sleeve 31 is fitted over the outside of the tree 2 and spaced apart from the roots of the tree 2. Multiple support rods 32 are provided and spaced apart around the mounting sleeve 31. One end of the support rod 32 is connected to the mounting sleeve 31, and the other end is inclined in a direction away from the tree 2, with the end of the support rod 32 close to the hillside 1 abutting against the ground. By supporting the tree 2 with multiple support rods 32, the tendency of the tree 2 to tilt during growth is reduced, facilitating plant growth.

[0049] Reference Figure 3 and Figure 4An installation block 4 is provided on the outer side of the installation sleeve 31, and a sliding groove 41 is formed on the installation block 4 in the vertical direction. The support rod 32 includes an integrally formed vertical part 321 and a support part 322. The vertical part 321 is arranged in the vertical direction and slides in the vertical direction within the sliding groove 41. The support part 322 and the end of the vertical part 321 near the ground are connected, and a fixing component 5 for fixing the position of the vertical part 321 is provided on the installation block 4. When supporting the tree 2, the position of the support part 322 is adjusted by sliding the vertical part 321 until the support part 322 abuts against the ground, and then the vertical part 321 is fixed by the fixing component 5. This allows the support part 322 to abut against different positions on the ground to support the tree 2. That is, even when the position where the support part 322 contacts the support surface is inclined or uneven, the support part 322 can still support the tree 2, meeting the needs of more construction environments.

[0050] Reference Figure 3 and Figure 4 The vertical portions 321 and mounting sleeves 31 are spaced apart. Multiple mounting blocks 4 and multiple support rods 32 are correspondingly provided, and multiple sliding grooves 41 are arranged in the same plane. The fixing assembly 5 includes a fixing sleeve 51, a fixing block 52, and a fixing pin 53. The fixing sleeve 51 is annular and is mounted on the mounting block 4, fitting around the outside of the multiple vertical portions 321. The fixing block 52 is located inside the fixing sleeve 51, with one end of the fixing block 52 facing away from the fixing sleeve 51 spaced apart from the inner wall of the fixing sleeve 51. The inner side of the fixing sleeve 51 abuts against the side of the vertical portion 321, and the fixing sleeve 51 is rotatably mounted outside the vertical portion 321. A through hole 511 is provided through the fixing sleeve 51, and the fixing pin 53 is inserted into the through hole 511.

[0051] Reference Figure 3 and Figure 4When it is necessary to fix the support plate, rotate the fixing sleeve 51. The fixing sleeve 51 drives the fixing block 52 toward the vertical part 321 until the vertical part 321 moves to the gap between the fixing block 52 and the fixing sleeve 51. At the same time, the side of the fixing block 52 abuts against the vertical part 321, locking and fixing the vertical part 321. At this time, the through hole 511 moves to the side of the vertical part 321, and then the fixing pin 53 is inserted into the through hole 511, so that the side of the fixing pin 53 abuts against the side of the vertical part 321, that is, the vertical part 321 is locked between the fixing part and the fixing pin 53, reducing the phenomenon of reverse rotation of the fixing sleeve 51, and fixing the support rod 32. The end of the fixing block 52 away from the fixing sleeve 51 is set in a pointed shape, that is, the distance between the end of the fixing block 52 and the fixing sleeve 51 is increased, so that when the fixing sleeve 51 rotates, the fixing block 52 can easily move to abut against the side of the vertical part 321, so as to fix the support rod 32. Multiple fixing blocks 52 are provided, and the multiple fixing blocks 52 are spaced apart around the fixing sleeve 51. The multiple fixing blocks 52 and the multiple vertical parts 321 are arranged one-to-one. When the fixing sleeve 51 rotates, it drives the multiple fixing blocks 52 to rotate at the same time, thereby fixing the position of the multiple support rods 32 simultaneously, improving the fixing efficiency of the support rods 32.

[0052] Reference Figure 5 and Figure 6 A snap-fit ​​sleeve 6 is provided inside the mounting sleeve 31. A mounting groove 311 is formed in the side wall of the mounting sleeve 31. A snap-fit ​​rod 61 is provided on the snap-fit ​​sleeve 6. The snap-fit ​​rod 61 is connected to the side of the snap-fit ​​sleeve 6 opposite to the center of the mounting sleeve 31. The snap-fit ​​rod 61 extends through the mounting sleeve 31 into its interior and slides along the center of the mounting sleeve 31. A linkage block 7 is provided inside the mounting groove 311. The linkage block 7 slides around the center of the mounting sleeve 31 within the mounting groove 311. A guide slope 71 is formed on the side of the linkage block 7 near the center of the mounting sleeve 31. The end of the snap-fit ​​rod 61 abuts against the guide slope 71. At least two sets of snap-fit ​​sleeves 6 and snap-fit ​​rods 61 are provided, with multiple sets of snap-fit ​​sleeves 6 and snap-fit ​​rods 61 spaced apart around the center of the mounting sleeve 31. In this embodiment, two sets are provided. When the linkage block 7 moves, it guides the different positions on the inclined plane 71 and the locking rod 61 to slide, thereby driving the locking sleeve 6 to move until the locking sleeve 6 moves to abut against the side of the tree 2, fixing the mounting sleeve 31 to the tree 2.

[0053] Reference Figure 5 and Figure 6An opening 312, communicating with the mounting groove 311, is made on the side of the mounting sleeve 31 closest to the ground. A linkage rod 8 is provided on the linkage block 7, extending through the opening 312 to the outside of the mounting groove 311. A push rod 9 is provided on the fixing sleeve 51, located inside the fixing sleeve 51 and oriented towards the center of the mounting sleeve 31. When the fixing sleeve 51 is rotated, it simultaneously engages the fixing block 52 and the vertical part 321, causing the push rod 9 and the linkage rod 8 to abut against each other. Continuing to rotate the fixing sleeve 51, the push rod 9 and the linkage rod 8 move the linkage block 7, causing the locking sleeve 6 to move, thus fixing the support rod 32 while simultaneously fixing the mounting sleeve 31 and the tree 2.

[0054] Reference Figure 5 and Figure 6 The mounting sleeve 31 includes two semi-circular mounting portions, one end of which is rotatably connected, and the other end is connected by bolts. Each mounting portion has a mounting groove 311 for mounting the snap-fit ​​rod 61. The fixing sleeve 51 includes two semi-circular fixing portions, which are fixedly connected by bolts. Both the mounting sleeve 31 and the fixing sleeve 51 are fixedly connected by bolts for installation.

[0055] The implementation principle of this application is as follows: Trees 2 are planted in planting area 11, and water and soil are blocked by water-blocking plate 12 to reduce water runoff. Then, the installation sleeve 31 is fitted onto the outside of the tree 2, the position of the vertical part 321 is adjusted, the end of the support part 322 is placed on the ground, and then the fixing sleeve 51 is rotated to fix the position of multiple support rods 32. At the same time, the snap-fit ​​sleeve 6 and the tree 2 are driven to abut against each other to fix the installation sleeve 31. The operation is simple and improves construction efficiency. At the same time, the support rods 32 and the installation sleeve 31 support the tree 2 to reduce the phenomenon of tree 2 tilting, so as to promote the growth of tree 2.

[0056] This application also discloses a construction technique for a mountain afforestation slope, which adopts the above-mentioned mountain afforestation slope.

[0059] S2, bury the baffle on the side of the planting area 11 near the bottom of the slope;

[0060] S3, the mounting sleeve 31 is placed on the outside of the tree 2 and then fixed with bolts. Then, the linkage rod 8 is manually rotated to drive the snap sleeve 6 to abut against the side of the tree 2 to pre-fix the mounting sleeve 31.

[0061] S4, the fixing sleeve 51 is installed on the outside of the mounting block 4 by bolts;

[0062] S5, adjust the position of each vertical part 321 so that the ends of each support part 322 are placed on the ground;
