Abstract
Description
Technical Field
[0001] This utility model relates to the field of slope protection technology, and in particular to a slope protection device using plant fiber blankets. Background Technology
[0002] Slope protection is a crucial issue in civil engineering and environmental engineering, especially in highway, railway, water conservancy, and mining projects. Slope instability leading to soil erosion and landslides poses a dual threat to both project safety and the ecological environment. Traditional slope protection technologies are mainly divided into two categories: rigid structures and flexible ecological protection. While traditional rigid structures such as concrete grids and masonry slope protection can effectively resist erosion, their sealed surfaces completely block the natural connection between soil and vegetation, leading to the loss of slope ecological function. Flexible ecological protection, such as laying plant fiber blankets, can cover the topsoil and promote vegetation growth in the short term, but its low tensile strength makes it prone to overall displacement or tearing under heavy rain or slope runoff. Therefore, current slope protection methods often employ a balanced approach using both rigid structures and flexible ecological protection.
[0003] Patent application CN202421126472.7 discloses a plant fiber blanket slope protection and water storage structure, including a slope body. The slope body has a water-retaining and wetting mechanism on its exterior and a fiber blanket fixing mechanism on its exterior. The fiber blanket fixing mechanism includes a plant fiber blanket body, which is laid on the exterior of the slope body. An installation column is fixedly installed inside the slope body. A stop block is fixedly installed on the top of the installation column. A sliding seat is slidably installed on the exterior of the installation column. A fixing spring is fixedly installed between the top of the sliding seat and the bottom of the stop block. A fixing buckle is fixedly installed on the top of the sliding seat. A pressure band is provided inside the fixing buckle to facilitate slope protection via the plant fiber blanket body. This structure uses a fixing column and pressure band to fix the plant fiber blanket; however, relying solely on the pressure band to press the plant fiber blanket together results in unstable fixation, and the plant fiber blanket easily slips off the slope. Therefore, this application proposes a slope protection device using a plant fiber blanket to solve the above problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All directional indicators (such as up, down, left, right, front, back, etc.) in the present utility model are only used to explain the relative positional relationship and movement of each component in a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indicator will also change accordingly.
[0021] like Figure 1-6 As shown, this embodiment provides a slope protection device using plant fiber blankets, including a slope body 1, the surface of which is covered with a plant fiber blanket 2. The fiber material of the plant fiber blanket 2 is at least one of coconut fiber, straw, or jute, with a unit area weight of 200-500 g / m². 2 The degradation cycle is 2-3 years. The plant fiber blanket 2 is premixed with grass seeds, water-retaining agent and fertilizer. The plant fiber blanket 2 is provided with a number of positioning rings 3. The positioning rings 3 are distributed in a matrix. Adjacent positioning rings 3 are connected by rigid plates 4. The positioning rings 3 on adjacent plant fiber blankets 2 are also connected by rigid plates 4. The positioning rings 3 are slidably inserted with posts 5, and the posts 5 are inserted into the slope body 1, thereby fixing the plant fiber blanket 2 to the slope body 1. Trees or ground lights can be planted or installed in the slope body 1 located in the positioning rings 3 to improve aesthetics and lighting functions.
[0022] Furthermore, such as Figure 2-5As shown, the plant fiber blanket 2 has several matrix-distributed through grooves 21. The through grooves 21 are matrix-distributed in the plant fiber blanket 2, and the outer through grooves 21 are close to the edge of the plant fiber blanket 2. The distance between adjacent through grooves 21 is 1-2m. The positioning ring 3 is located at the through groove 21. Specifically, the positioning ring 3 includes a lower ring plate 31 and an upper ring plate 32 with the same shape and size. The through groove 21, the lower ring plate 31 and the upper ring plate 32 have the same planar shape, and the outer contour size of the lower ring plate 31 and the upper ring plate 32 is larger than the contour size of the through groove 21. Specifically, the planar shape of the through groove 21, the lower ring plate 31 and the upper ring plate 32 can be circular, polygonal, elliptical or pentagonal. In this example, a circular shape is used. The lower ring plate 31 and the upper ring plate 32 are connected by circumferentially distributed rivets 33. The plant fiber blanket 2 is located between the lower ring plate 31 and the upper ring plate 32. The lower ring plate 31 is located on one surface of the plant fiber blanket 2 that is in contact with the slope body 1. Of course, the lower ring plate 31 can also be located on the upper surface of the plant fiber blanket 2. The two ends of the rigid plate 4 are connected to the lower ring plate 31. The upper ring plate 32 and the lower ring plate 31 sandwich the plant fiber blanket 2 in the middle, and the upper ring plate 32 and the lower ring plate 31 are fixed together with the plant fiber blanket 2 by the rivets 33.
[0023] Furthermore, such as Figure 1 , 5 As shown, both the upper ring plate 32 and the lower ring plate 31 are provided with several circumferentially distributed through holes 34. The through holes 34 on the upper ring plate 32 and the lower ring plate 31 correspond one to one and are coaxially arranged. The through holes 34 are staggered from the rivets 33. The lower end of the insert 5 is conical. The insert 5 passes through the through hole 34 and is inserted into the slope body 1 to fix the positioning ring 3 on the slope body 1, thereby fixing the plant fiber blanket 2 on the slope body 1.
[0024] Furthermore, such as Figure 5 , 6 As shown, the lower ring plate 31 has several grooves 35 on one surface opposite to the upper ring plate 32. The end of the rigid plate 4 is inserted into the groove 35 and the end of the rigid plate 4 is provided with a positioning hole 41. The groove 35 is provided with a through hole 34. The insert 5 passes through the positioning hole 41. The inner cavity size of the groove 35 is the same as the end size of the rigid plate 4, so that the rigid plate 4 can be inserted into the groove 35. When the insert 5 passes through the through hole 34, it can also pass through the positioning hole 41 on the rigid plate 4, thereby fixing the rigid plate 4. The rigid plate 4 is made of stainless steel. The width of the rigid plate 4 is 2-5cm and the thickness is 0.2-0.5cm. The rigid plate 4, together with the positioning ring 3, can provide rigid support for the plant fiber blanket 2.
[0025] Its working principle is as follows: When the plant fiber blanket 2 is prepared, a through groove 21 is reserved. Then, the upper ring plate 32 and the lower ring plate 31 are fixed to the through groove 21 by rivets 33. When the plant fiber blanket 2 is laid flat on the slope body 1, the rigid plate 4 is inserted into the groove 35 of the two adjacent lower ring plates 31. Then, the insert 5 is inserted into the slope body 1 through the through hole 34 to fix the plant fiber blanket 2. The positioning ring 3 is used in conjunction with the insert 5 to fix the plant fiber blanket 2 to the slope body 1. The positioning ring 3 is connected together by the rigid plate 4 to ensure the integrity of the plant fiber blanket 2, forming a synergistic protection mechanism, which improves the tensile strength of the plant fiber blanket 2. The plant fiber blanket 2 is fixed stably, which can prevent the plant fiber blanket 2 from slipping out of the slope body 1, adapt to different slope slopes, facilitate construction, and ensure the construction progress.
