Description

Technical Field

[0001] The invention relates to the technical field of slope reinforcement, and in particular to a slope vegetation fixing device and method for preventing soil loss. Background Art

[0002] Soil erosion refers to the phenomenon that due to natural or human factors, rainwater cannot be absorbed locally, flows down and washes the soil, causing the loss of water and soil at the same time. The main reasons are large ground slope, improper land use, destruction of ground vegetation, loose soil, deforestation, overgrazing, etc. Especially for soil and water conservation on some slopes, the most commonly used method is to reinforce and plant to make the slope more stable and reduce the impact of rainwater scouring on the slope to prevent soil erosion.

[0003] The existing fixing devices generally fix the protection net on the slope by anchor rods, and then assist with vegetation planting to protect the slope. This method is relatively simple. When in use, it is necessary to use tools such as a sledgehammer to directly hammer the anchor rod into the slope. Since the slope reinforcement work is carried out outdoors, the workers also need to carry tools such as a sledgehammer to the workplace when carrying the fixing device. The sledgehammer and other tools have a large weight, which makes the labor burden of the workers heavy. At the same time, the anchor rod inserted into the ground can only form an anchoring force perpendicular to the ground, and the fixing effect is poor. After long-term use, the anchor rod will be easily pulled out of the ground due to the lack of lateral limiting force, thereby reducing the anchoring performance of the device, and further reducing the effect of the slope reinforcement work.

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Example 1

[0037] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, comprises a slope vegetation fixing device for preventing soil erosion, comprising:

[0038] The reinforcement unit 100 includes two groups of pressure plates 101 laid at the upper and lower ends of the slope, multiple groups of fixed plates 102 arranged between the two groups of pressure plates 101, and the multiple groups of fixed plates 102 are staggered in the vertical direction, and a protective net 103 laid on the fixed plates 102 and completely covering the space between the pressure plates 101 and the fixed plates 102; the protective net 103 is a structure with a grid, and the vegetation growing from the slope can pass through the grid, and through the entanglement of the stems and leaves with the silk threads woven by the protective net 103, it plays a physical restraint role, and cooperates with the roots and stems to effectively prevent soil erosion.

[0039] The anchoring unit 200 includes a limiting component 201 fixedly set on the reinforcement unit 100, an anchoring component 202 vertically inserted into the limiting component 201, a pressure component 203 sleeved on the top of the anchoring component 202, a rotating shaft 204 arranged at the axial position of the anchoring component 202, two groups of reinforcement components 205 vertically distributed on the pressure component 203, and a driving component 206 arranged at the top of the rotating shaft 204, and the driving component 206 extends upward through the pressure component 203. There are multiple groups of anchoring units 200 in the whole device, and the anchoring units 200 are respectively fixed at different positions on the pressure plate 101 and the fixed plate 102 to play a role in reinforcing anchoring. The anchoring component 202 is in a rotationally connected relationship with the pressure component 203, and the rotating shaft 204 is rotationally connected to the axial position of the anchoring component 202. A space corresponding to the installation of the rotating shaft 204 and the reinforcement component 205 is opened in the anchoring component 202.

[0040] Among them, the pressure plate 101 and the fixed plate 102 can be combined to form a six-grid frame structure, and the protective net 103 is laid in each space of the six-grid. The number of fixed plates 102 is increased according to usage requirements, so that they can be combined with the pressure plate 101 to form nine-grid, twelve-grid and other structures of different numbers. The slope surface under each space is exposed, so vegetation can be planted in the space to form a planting window.

[0041] During use, the protective net 103 is laid on the slope where plant seeds have been planted, and two groups of pressing plates 101 are placed at the upper and lower ends of the slope. Different numbers of fixing plates 102 are selectively set up between the two groups of pressing plates 101. The pressing plates 101 and the fixing plates 102 cooperate to initially fix the protective net 103 laid on the slope to prevent the protective net 103 from falling off. At the same time, different numbers of fixing plates 102 can constitute planting windows of different sizes and numbers. Subsequently, the anchoring unit 200 is installed on the pressing plate 101 and the fixing plate 102, and the end of the anchoring component 202 is inserted into the limiting component 201. The anchoring component 202 is driven downward into the ground by pressing the pressure component 203. When the pressure component 203 applies downward pressure to the anchoring component 202, the limiting component 201 cooperates with the anchoring component 202 to The downward pressure is converted into a force for the anchoring component 202 to rotate downward. Eventually, the anchoring component 202 will be anchored into the ground in a rotational manner, thereby playing the role of anchoring the reinforcement unit 100. After the anchoring component 202 at the lower end of the anchoring unit 200 penetrates into the slope, the driving component 206 drives the rotating shaft 204 to stimulate the two groups of reinforcement components 205. The two groups of reinforcement components 205 can increase the lateral contact area between the anchoring unit 200 and the slope, and enhance the anchoring performance of the anchoring unit 200. After the plants take root and sprout, the roots of the plants will combine and reinforce the land in the slope. The upper part of the plants will grow upward and pass through the protective net 103. The stems and leaves of the plants passing through the protective net 103 will be entangled with the protective net 103, playing a physical restraint role, and cooperating with the roots and stems to effectively prevent soil erosion.

[0042] Example 2

[0043] Reference Figure 2 to Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the anchoring component 202 is driven to cooperate with the limiting component 201 by pressing the pressure component 203, so as to realize the automatic drilling function of the anchoring component 202, reduce the carrying of additional tools, and reduce the burden on workers.

[0044] Compared with Example 1, further, referring to Figure 6 The limiting component 201 includes a base 201a fixedly connected to the fixing plate 102, a socket 201b opened in the base 201a, and the anchoring component 202 is inserted in the socket 201b, and four groups of guide components 201c equally divided on the inner wall of the base 201a in an annular shape, and each group of guide components 201c is composed of three balls, and the three balls are distributed on the inner wall of the base 201a at a spiral inclination angle. Each group of balls is rotatably embedded in the inner wall of the base 201a, and can rotate freely on the inner wall of the base 201a without changing its position.

[0045] Among them, refer to Figure 3The anchoring component 202 includes an anchor rod 202a vertically inserted into the socket 201b, four groups of guide grooves 202b equally divided in annular shape on the outer wall of the anchor rod 202a, and each group of guide grooves 202b is opened on the anchor rod 202a in a spiral winding manner, a transfer ball 202c is arranged on the top of the anchor rod 202a, and the top of the transfer ball 202c is a hemispherical structure, and a limit groove 202d is opened on the anchor rod 202a and corresponds to the position of the reinforcement component 205.

[0046] During use, refer to Figure 3 The end of the anchor rod 202a is a conical head with a spiral, which can drill into the ground more easily. The hemispherical structure at the top of the transfer ball 202c has the effect of uniform force. Therefore, when the pressure-applying component 203 applies downward pressure, the spherical structure of the transfer ball 202c cooperates with the hemispherical groove 203c, which can facilitate the rotation of the anchor component 202 without affecting the downward pressure applied by the pressure-applying component 203, reduce the friction between the two, and make the anchor component 202 rotate more smoothly.

[0047] Furthermore, the spiral angle of the guide groove 202b matches the guide component 201c, and one side of the guide component 201c is located in the guide groove 202b. The limit groove 202d is composed of four groups of notches distributed in a ring with the axis of the anchor rod 202a as the center, and the outer end of each group of notches passes through the anchor rod 202a and is connected to the outside. Since the spiral angle of the guide groove 202b matches the guide component 201c, the spiral motion trajectories of the two are the same.

[0048] Among them, refer to Figure 4 The pressure-applying component 203 includes a sleeve 203a sleeved on the transfer ball 202c, and the sleeve 203a is rotatably connected to the transfer ball 202c, handles 203b are symmetrically fixed on both sides of the sleeve 203a, and hemispherical grooves 203c are opened inside the sleeve 203a and match the structure of the transfer ball 202c. The handles 203b on both sides of the sleeve 203a can be used for grasping or stepping, so that the staff can apply pressure to the pressure-applying component 203 through the handles 203b.

[0049] In summary, combined Figure 5When anchoring the reinforcement unit 100, the sleeves 203a on both sides of the pressure component 203 are pressed, and the pressure component 203 applies downward pressure to the anchor component 202 as a whole through the transfer ball 202c. When the anchor component 202 moves downward, the guide groove 202b with a spiral angle opened on the outside abuts against the guide component 201c, and the guide component 201c and the guide groove 202b have the same spiral angle. Therefore, when the anchor component 202 moves downward, the guide groove 202b exerts downward pressure on the ball of the guide component 201c, and the guide component 201c is The ball will deflect and guide the downward pressure applied by the guide groove 202b by rotating. Through the cooperation between the guide groove 202b and the guide assembly 201c, the vertical downward pressure exerted by the pressure-applying component 203 on the anchor rod 202a will be converted into a spiral downward force. At this time, the anchor rod 202a as a whole will be drilled into the slope in a rotating manner, so that the anchoring unit 200 has an automatic drilling function. During this process, there is no need to use additional tools for guidance, and the function of anchoring the anchoring unit 200 into the slope can be completed, thereby reducing the need for workers to carry additional tools and alleviating the burden on workers.

[0050] The remaining structures are the same as those of Example 1.

[0051] Example 3

[0052] Reference Figure 7 to Figure 10 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that two groups of reinforcement components 205 in the anchor component 202 are unfolded by the rotating shaft 204. The unfolded reinforcement components 205 can increase the lateral contact between the anchor component 202 and the slope, increase the limiting resistance in the vertical direction between the anchor component 202 and the slope, and further enhance the anchoring performance of the anchor unit 200.

[0053] Compared with Example 2, further, the rotating shaft 204 is coaxial with the anchoring component 202, and the rotating shaft 204 is rotatably connected to the axial position of the anchoring component 202. A limiting plate for limiting is provided at the end of the rotating shaft 204, and the rotating shaft 204 can rotate at the axial position of the anchor rod 202a.

[0054] Among them, refer to Figure 7 The reinforcing component 205 includes a driving disk 205a which is laterally fixed on the rotating shaft 204, and the driving disk 205a is coaxial with the rotating shaft 204, four groups of reinforcing teeth 205b which are equally divided and arranged around the bottom of the driving disk 205a, and the four groups of reinforcing teeth 205b extend into the limiting groove 202d accordingly, four groups of annular driving grooves 205c which are equally divided and have an arc-shaped structure on the driving disk 205a, and a limiting shaft 205d which is arranged on the top surface of the inner end of the reinforcing tooth 205b in a corresponding vertical direction, and the limiting shaft 205d extends upward into the driving groove 205c.

[0055] During use, the driving disk 205a is fixedly connected to the rotating shaft 204, so the driving disk 205a can be driven by the rotating shaft 204 to rotate, and the reinforcing teeth 205b are located in the limiting groove 202d, so the two sides of the guide groove 202b are limited by the limiting groove 202d, and can only perform horizontal telescopic sliding in the guide groove 202b. The inner end of the arc-shaped structure of the driving groove 205c is close to the center of the driving disk 205a, and the other end is close to the edge of the driving disk 205a. The limiting shaft 205d extends into the driving groove 205c, so the driving groove 205c is limited by the driving groove 205c, and at the same time, the limiting shaft 205d slides in the driving groove 205c.

[0056] Among them, refer to Figure 8 The driving component 206 includes a connecting rod 206a fixedly connected to the top of the rotating shaft 204 in a vertical direction, a toggle rod 206b inserted in the connecting rod 206a, a receiving groove 206c vertically opened on the connecting rod 206a, and the toggle rod 206b is inserted in the receiving groove 206c, sliding grooves 206d are opened on both sides of the connecting rod 206a, fixed shafts 206e symmetrically arranged on both sides of the end of the toggle rod 206b, and the fixed shaft 206e extends outward into the sliding groove 206d, and a threaded cap 206f is arranged on the top of the toggle rod 206b.

[0057] During use, the connecting rod 206a is fixedly connected to the top of the rotating shaft 204, so the connecting rod 206a can drive the rotating shaft 204 to rotate, thereby driving the two sets of reinforcement components 205 to move synchronously, and the toggle rod 206b is inserted through the fixed shafts 206e on both sides and can slide freely in the connecting rod 206a, and the toggle rod 206b that slides out of the connecting rod 206a can rotate with the fixed shaft 206e as the axis. 6a is vertical, and the end of the toggle rod 206b is still located in the storage groove 206c opened with the connecting rod 206a, so the toggle rod 206b is still limited by the connecting rod 206a. When the toggle rod 206b perpendicular to the connecting rod 206a rotates, a lever structure will be formed to synchronously drive the connecting rod 206a to rotate. The threaded cap 206f is a hexagonal structure, and when necessary, the driving component 206 can be driven to rotate by a wrench, providing an additional driving method.

[0058] In summary, after the anchoring component 202 is anchored into the soil layer on the slope, the toggle rod 206b is pulled upward to flip the pulled toggle rod 206b outward, and then the toggle rod 206b is held and pushed to rotate the toggle rod 206b around the rotating shaft 204. The rotating toggle rod 206b will drive the driving component 206 to rotate as a whole, and the driving component 206 will synchronously drive the driving disk 205a to move through the rotating shaft 204, and the rotating driving disk 205a will synchronously drive the driving slot 205c to move, and the moving driving slot 205c will synchronously drive the limiting member located therein. The limiting shaft 205d rotates with the driving disk 205a as the axis. Since the limiting shaft 205d is fixedly connected to the reinforcing tooth 205b and the reinforcing tooth 205b is limited by the limiting groove 202d, the driving disk 205a will push the reinforcing tooth 205b and the limiting shaft 205d to slide in the horizontal direction through the arc structure of the driving groove 205c. As the driving disk 205a rotates, the limiting shaft 205d moves from the inner end to the outer end of the driving groove 205c, and the reinforcing tooth 205b fixedly connected below the limiting shaft 205d also gradually extends outward from the limiting groove 202d (refer to Fig.10 ), the four groups of reinforcing teeth 205b move synchronously and will be laterally inserted into the soil layer on the slope from four directions. The four groups of drive grooves 205c that are laterally expanded can increase the lateral contact between the anchor rod 202a and the slope, further enhancing the connectivity between the anchor component 202 and the slope, thereby improving the pull-out resistance of the anchor component 202 and ensuring the anchoring effect.

[0059] The remaining structure is the same as that of Example 2.

[0060] Example 4

[0061] This is the third embodiment of the present invention, which provides a method for using a slope vegetation fixing device for preventing soil erosion, comprising the following steps:

[0062] S1. Lay the protection net 103 on the slope where the plant seeds have been planted, place two sets of pressing plates 101 at the upper and lower ends of the slope, and then use the anchoring unit 200 to cooperate with the two sets of pressing plates 101 to press and fix the two ends of the protection net 103, so as to achieve the preliminary fixation of the protection net 103;

[0063] S2. Selectively set up different numbers of fixing plates 102 between two groups of pressing plates 101, and fix the fixing plates 102 on the slope through anchoring units 200. The fixing plates 102 can further press and fix the protection net 103 on the slope surface in the horizontal direction to prevent the protection net 103 from falling off. At the same time, different numbers of fixing plates 102 can form planting windows of different sizes and numbers, which are the spaces between each two adjacent groups of fixing plates 102.

[0064] S3. After the anchoring unit 200 anchors the pressure plate 101 and the fixing plate 102, the anchoring component 202 at the lower end of the anchoring unit 200 penetrates into the slope, and then the driving component 206 drives the rotating shaft 204 to stimulate the two sets of reinforcement components 205. The two sets of reinforcement components 205 can increase the lateral contact area between the anchoring unit 200 and the slope, thereby enhancing the anchoring performance of the anchoring unit 200.

[0065] S4. After the plants take root and sprout, the root system of the plants will combine and reinforce the land in the slope, the upper part of the plants will grow upward and pass through the protective net 103, and the stems and leaves of the plants passing through the protective net 103 will be entangled with the protective net 103, playing a physical restraint role, and cooperating with the roots and stems to effectively prevent soil erosion.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
