Description

Technical Field

[0001] The invention relates to the field of slope ecological restoration, and in particular to a high and steep slope ecological restoration system. Background Art

[0002] Traditional slope protection focuses on the stability of the slope protection structure, and often uses stone or concrete masonry retaining walls as the surface. This overcomes the problems of soil erosion and landslides caused by the slope, but also brings environmental problems such as visual gray pollution and ecological imbalance. With the rapid development of my country's economy, infrastructure construction has been vigorously promoted. During the implementation of water conservancy, transportation, mining, electricity and other construction projects, a large number of exposed slopes have been formed. The slope protection technology used for this needs not only to consider the stability of its structure, but also to bring about good landscape effects. Slope greening came into being. The main greening technologies in the existing slope lattice frame greening projects include vegetation bag technology, vegetation concrete ecological protection technology, vine vertical greening technology, etc.

[0003] The vegetation concrete ecological protection technology is suitable for high and steep slopes of 45°-75°. This technology requires laying a composite material mesh (galvanized wire mesh) on the slope surface first, and fixing it with anchor nails and anchor rods, and then using cement as a binder, configuring a special vegetation concrete greening additive, adding organic matter (fiber + organic matter or humus) content less than 20% (volume ratio), and configuring a mixture of planting soil, plant seeds, fertilizers, water and other materials. After stirring, it is sprayed onto the rock slope through a special spraying equipment. After two layered spraying, a 10cm thick anti-scouring nutrient vegetation concrete layer is formed, and finally covered with sun protection, moisture retention and irrigation maintenance slope ecological protection technology.

[0004] However, the existing vegetation concrete ecological protection technology is difficult and costly to lay composite material nets on steep slopes. At the same time, the vegetation in the vegetation concrete ecological protection technology is prone to water shortage and soil loss, which is not conducive to ecological restoration. Summary of the invention

[0005] One object of the present invention is to provide a high and steep slope ecological restoration system, which can quickly and conveniently lay a connecting net on a high and steep slope, is simple and convenient to operate, and effectively saves costs.

[0006] This purpose is achieved by adopting the following technical solutions:

[0007] A high and steep slope ecological restoration system includes two fixed plates respectively arranged on both sides of the slope, the fixed plates are fixed on both sides of the slope, and the two fixed plates have the same structure. A slide groove is arranged on each fixed plate, and the direction of the slide groove is the same as the direction of the length of the fixed plate, and the direction of the slide groove is the same as the direction of the slope of the slope.

[0008] The lower end of the fixed plate is provided with a fixed adjustment piece, and the slide groove is provided with a plurality of sliding adjustment pieces. The fixed adjustment piece and the plurality of sliding adjustment pieces on the same fixed plate are located on the same straight line; the sliding adjustment piece can slide in the slide groove along the direction of the slide groove.

[0009] Both the fixed adjusting member and the sliding adjusting member are provided with connecting plates, and a connecting net is connected between the connecting plates corresponding to each other on both sides of the slope, wherein the connecting plates corresponding to each other on both sides of the slope refer to the fixed plates on both sides of the slope, two fixed adjusting members correspond to each other, and several sliding adjusting members correspond one to one, and the connecting net is connected between the connecting plates of the two corresponding fixed adjusting members, and the connecting net is connected between the connecting plates of the two corresponding sliding adjusting members.

[0010] The fixed adjusting member and the sliding adjusting member make the plurality of connection nets parallel to each other, and make the angles between the plurality of connection nets and the slope be 0-60 degrees.

[0011] When the angle between the several connection nets and the slope is 0 degree, the several connection nets are all laid flat on the slope, and two adjacent connection nets are in contact with each other up and down, and the several connection nets are on the same plane, achieving the effect of laying the several connection nets on the slope.

[0012] When the angle between the plurality of connection nets and the slope is 60 degrees, the planes where the plurality of connection nets are located are parallel to each other and are not coplanar, and the plurality of connection nets are all located at the lower end of the slope.

[0013] Before laying, several connecting nets are located at the lower end of the slope and are parallel to each other. When laying is required, the sliding adjustment part slides from bottom to top in the slide groove, and drives several connecting nets to move upward in sequence. After the sliding adjustment part moves to the corresponding position, it drives the connecting net to rotate until the angle between it and the slope is 0 degrees, that is, the connecting net is laid on the slope.

[0014] This system is more suitable for high and steep slopes. When using this system, the staff does not need to climb up to install the tripod one by one, nor does the staff need to climb up to lay the connecting net one by one after the tripod is installed. When laying, the laying can be achieved directly by sliding the sliding adjustment part in the slide groove and adjusting the sliding adjustment part to drive the connecting plate to rotate. The operation is simple and convenient.

[0015] The sliding adjustment member and the fixed adjustment member may have various structures, as long as they can achieve the effect of driving the connecting plate to rotate and slide in the slide groove.

[0016] In order to further simplify the operation, the inventor preferably selects a structure of a fixed adjusting member and a sliding adjusting member.

[0017] Specifically, the fixed adjusting member and the sliding adjusting member have the same structure, and both the fixed adjusting member and the sliding adjusting member include a first gear and a second gear that mesh with each other, a connecting plate is connected to the first gear and the second gear, the connecting plate is connected to the first gear, the centers of the circles of the first gears and the second gears are located on the same straight line, and the first gear and the second gear in the middle are connected to an adjusting rod, wherein, among the fixed adjusting member and the plurality of sliding adjusting members, the lowermost is the first gear on the fixed adjusting member, and the uppermost is the second gear in the sliding adjusting member, and the first gear and the second gear in the middle refer to the other first gears and the second gears except the lowermost first gear and the uppermost second gear.

[0018] In the fixed adjustment member and the sliding adjustment member, when the first gear rotates, the first gear acts on the second gear it meshes with. In the same sliding adjustment member and the fixed adjustment member, the first gear and the second gear rotate in opposite directions.

[0019] Furthermore, in the first gear and the second gear located in the middle, the adjusting rods on the adjacent first gear and the second gear are hingedly connected; the first gear and the second gear in the sliding adjustment member are connected through a connecting plate, and both the first gear and the second gear can rotate circumferentially on the connecting plate.

[0020] When in use, the sliding adjustment member slides in the slide groove. During the upward sliding process of the sliding adjustment member, the two adjustment rods on the two adjacent sliding adjustment members rotate. During the rotation of the two adjustment rods, the first gear in one of the sliding adjustment members and the second gear in the other sliding adjustment member are driven to rotate in the opposite direction. When the first gear in one of the sliding adjustment members rotates, it drives the connecting plate thereon to rotate. When the second gear in the other sliding adjustment member rotates, it acts on the corresponding first gear, driving the corresponding first gear to rotate in the opposite direction, thereby making all the first gears rotate in the same direction, so that when the sliding adjustment member slides in the slide groove, it drives the connecting net thereon to rotate and lay flat on the slope.

[0021] Meanwhile, preferably, the distance between two adjacent first gears is the same as the width of the connecting net, so when the angle between the connecting net and the slope is 0 degrees, the upper and lower ends of the two adjacent connecting nets are in contact with each other.

[0022] When the angle between the connecting net and the slope is 60 degrees, the sliding adjustment members contact each other and are located at the lower end of the slide slot, and the planes where the connecting nets are located are parallel to each other and not coplanar. The sliding adjustment member slides in the slide slot, causing the first gear and the second gear to rotate, driving the connecting nets to move upward and be laid on the slope in sequence, so that the connecting nets are located on the same plane.

[0023] Furthermore, when the system is in operation, all the first gears and the second gears can be rotated in sequence by directly rotating the first gear on the fixed adjustment member, and the sliding adjustment member can slide in the slide groove, which is more convenient for operation and adjustment.

[0024] On the other hand, a plurality of fixed cylinders are arranged at the lower end of the connecting net, and the plurality of fixed cylinders include four rotating rings arranged in sequence from top to bottom, and the four rotating rings can rotate circumferentially on the fixed cylinders. Rectangular frames are connected to the rotating rings, and the four rectangular frames are parallel to each other, and the four rectangular frames overlap with each other or form a rectangle; when the four rectangular frames form a rectangle, the four rectangular frames are located on two adjacent connecting nets.

[0025] When the angle between the connecting net and the slope is 60 degrees, the four rectangular frames overlap with each other and are all located on one connecting net. When the angle between the connecting net and the slope is 0 degrees, the four rectangular frames form a rectangle, two of which are located on one connecting net and the other two are located on another connecting net.

[0026] When the angle between the connection net and the slope is 0 degrees, the connection net is laid on the slope, and the four rectangular frames act on two adjacent connection nets. The four rectangular frames can further connect the two connection nets. When the connection net located below falls off, the rectangular frames can provide further support to prevent the connection net from falling off. At the same time, preferably, the distance between two adjacent fixed cylinders is less than the sum of the lengths of the two rectangular frames. When the four rectangular frames form a rectangle, the adjacent rectangular frames partially overlap. This further increases the area where rainwater stays, and further increases the connection stability between two adjacent connection nets.

[0027] At the same time, a number of through holes are provided on the rotating ring, and the through holes connect the outside of the side of the fixed cylinder with the inside of the fixed cylinder. A grid plate is provided in the rectangular frame, and the grid plate is a plant grid plate, on which plants can be further planted, which can help fix the soil and prevent soil and water loss, and also facilitate the growth of plant roots. The four rectangular frames have different heights, and the four rectangular frames of different heights are located on the slope. When it rains, the uneven rectangular frames can further hinder the rapid fall of rainwater, increase the time that rainwater stays in the rectangular frames, and then allow more rainwater to enter the fixed cylinder. The rainwater enters the plants on the grid plate through the fixed cylinder, reducing soil loss while solving the problem of vegetation being prone to water shortage.

[0028] Preferably, the height of the fixing tube is 10-15 cm, and the inner diameter of the fixing tube is 5-10 cm. Plants can also be planted in the fixing tube to further improve the stability of the connection.

[0029] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0030] The present invention discloses a high and steep slope ecological restoration system. The system can be used for high and steep slopes. For the ecological restoration of high and steep slopes, when laying a connecting net, there is no need to set up a tripod, and there is no need to manually climb up to lay the net in sequence. Adjustment can be made directly through the first gear on the fixed adjustment part below, which is more convenient to operate and use, and can greatly save costs.

[0031] After the connecting net is laid, the rotating ring on the connecting net is adjusted to rotate circumferentially on the fixed cylinder, driving the rectangular frame to rotate to form a rectangle, thereby further connecting two adjacent connecting nets. At the same time, the rectangular frames on two adjacent fixed cylinders on the same connecting net partially overlap, which can improve the stability of the connection.

[0032] And after being connected, the staggered rectangular frames can further increase the retention of rainwater, avoiding the problem of plants lacking water due to rain falling too quickly. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Example 1

[0048] The system comprises two fixing plates 1 respectively arranged on both sides of the slope, and the direction of the fixing plates 1 is the same as the direction of the slope surface where the slope is located.

[0049] The structure of the fixing plate 1 is as follows Figure 1 As shown, a slide groove 2 is provided on the fixed plate 1, and a fixed adjustment member is provided at the lower end of the fixed plate 1. Several sliding adjustment members are provided in the slide groove 2. The fixed adjustment member and several sliding adjustment members on the same fixed plate 1 are located on the same straight line; the fixed adjustment member and the sliding adjustment member have the same structure, and both the fixed adjustment member and the sliding adjustment member include a first gear 3 and a second gear 4 that mesh with each other, and a connecting plate 9 is connected to the first gear 3 and the second gear 4, and the connecting plate 8 is connected to the first gear 3, and the centers of the circles of several first gears 3 and second gears 4 are located on the same straight line. In this system, the lower end of the fixed plate is the lower end of the slope, and the lower end of the fixed plate 1 is provided with a fixed adjustment member. When the fixed plate is placed on the slope, the fixed adjustment member is located at the lower end of the fixed plate 1, and is also located at the lower end of the slope.

[0050] When the first gear 3 rotates counterclockwise, the second gear 4 meshing with the first gear 3 rotates clockwise. In order to make all the connecting plates 8 rotate synchronously, the first gear 3 and the second gear 4 in the middle are connected with an adjustment rod 5, and the adjustment rods 5 on the adjacent first gears 3 and second gears 4 in the middle are hinged. In the fixed adjustment member and the sliding adjustment member, the first gear 3 of the fixed adjustment member is located at the bottom, and the second gear 4 of the uppermost sliding adjustment member is located at the top;

[0051] The original state is Figure 1 As shown, the sliding adjustment member is located in the lower end of the slide, the angle between the connecting net 10 and the slope is 60 degrees, and the planes where the connecting plates 8 are located are parallel to each other and not coplanar. At the same time, the two corresponding connecting plates 8 on the two fixed plates form a plane, and the connecting net 10 is connected between the two corresponding connecting plates 8 on the fixed plates, and the planes where the connecting nets 10 are located are parallel to each other and not coplanar.

[0052] When the first gear 3 on the fixed adjusting member rotates clockwise, the second gear 4 meshing with the first gear 3 on the fixed adjusting member rotates counterclockwise. When the second gear 4 on the fixed adjusting member rotates counterclockwise, the adjusting rod 5 on the second gear 4 of the fixed adjusting member rotates counterclockwise, thereby driving the first sliding adjusting member in the slide groove to move along the slide groove, and in the process of moving, under the action of the adjusting rod, the first gear 3 of the first sliding adjusting member rotates clockwise, the second gear 4 of the first sliding adjusting member rotates counterclockwise. When the second gear 4 of the first sliding adjusting member rotates counterclockwise, the second sliding adjusting member is driven to move along the slide groove through the adjusting rod, and in the process of moving, under the action of the adjusting rod, the first gear 3 of the second sliding adjusting member rotates clockwise. When the first gear 3 of the second sliding adjusting member rotates clockwise, it acts on the second gear 4 of the second sliding adjusting member, causing the second gear 4 of the second sliding adjusting member to rotate counterclockwise, thereby driving the third sliding adjusting member to move along the slide groove through the adjusting rod, causing the first gear 3 of the third sliding adjusting member to rotate clockwise, and so on. Figure 2 The state shown, that is, the angle between the connecting plate 8 and the slope is 0 degrees. At this time, the two corresponding connecting plates 8 on the two fixed plates form a plane, and a connecting net 10 is connected between the two corresponding connecting plates 8 on the fixed plates, and the angle between several connecting nets 10 and the slope is also 0 degrees.

[0053] In some embodiments, when the angle between the connecting net 10 and the slope is 0 degrees, the sliding adjustment member slides in the slide groove 2, causing the first gear 3 and the second gear 4 to rotate, driving the connecting net 10 to move upward and be laid on the slope in sequence, so that several connecting nets 10 are located on the same plane; and when the angle between the connecting net 10 and the slope is 0 degrees, the upper and lower ends of two adjacent connecting nets 10 contact each other, thereby better realizing the slope laying.

[0054] In some embodiments, when the slope of the slope is too high, the hinge connection of the adjusting rod 5 is a connecting block 6, and the connecting block 6 is connected to a telescopic rod. The telescopic rod can further support the interaction between the two adjusting rods 5, further drive the adjusting rod to move, and drive the sliding adjustment part to move in the slide groove, thereby improving the stability of the paving.

[0055] In some embodiments, after the connection net is laid, the connection net can be fixed by further fixing the position of the sliding adjustment member in the slide groove.

[0056] Example 2

[0057] Based on the above embodiments, Figure 3 As shown, two ends of the connection net 10 are connected to two connection plates 8 respectively.

[0058] A plurality of fixing tubes 11 are provided at the lower end of the connecting net 10. The structure of the fixing tubes 11 is as follows: Figure 4 As shown, the plurality of fixed cylinders 11 include four rotating rings arranged sequentially from top to bottom, and the four rotating rings can rotate circumferentially on the fixed cylinder 11. The rotating rings are connected with rectangular frames, and the four rectangular frames are parallel to each other. When the four rectangular frames overlap each other, as shown in FIG. Figure 4 As shown, when four rectangular frames form a rectangle, such as Figure 5 and 6 As shown, when four rectangular frames form a rectangle, the four rectangular frames are parallel to each other, but have different heights, such as Figure 6 shown.

[0059] In some embodiments, the distance between two adjacent fixed tubes 11 is less than the sum of the lengths of the two rectangular frames. When four rectangular frames form a rectangle, since the heights of the four rectangular frames are different, the adjacent rectangular frames of two adjacent fixed tubes 11 partially overlap. Figure 7 shown.

[0060] In the original state, that is, when the angle between the connection net 10 and the slope is 60 degrees, the four rectangular frames overlap each other. When the angle between the connection net 10 and the slope is 0 degrees, as shown in FIG. Figure 8As shown, first, the four rectangular frames overlap with each other, and the four rectangular frames on the fixed tube 11 are the first rectangular frame 12, the second rectangular frame 13, the third rectangular frame 14 and the fourth rectangular frame 7 from top to bottom. When the four rectangular frames overlap with each other, the first rectangular frame 12, the second rectangular frame 13, the third rectangular frame 14 and the fourth rectangular frame 7 overlap with each other from top to bottom.

[0061] Rotate the rotating ring on the first rectangular frame 12, the rotating ring on the second rectangular frame 13, and the rotating ring on the third rectangular frame 14 so that the four rectangular frames form a rectangle. Fig. 9 As shown, between two adjacent fixed cylinders 11, the first rectangular frame 12 on the second fixed cylinder presses on the fourth rectangular frame 7 of the first fixed cylinder during rotation, and the second rectangular frame 13 on the second fixed cylinder presses on the third rectangular frame 14 of the first fixed cylinder during rotation.

[0062] In some embodiments, a plurality of through holes are provided on the rotating ring, and the through holes connect the outside of the side of the fixing tube 11 with the inside of the fixing tube 11. The height of the fixing tube 11 is 10-15 cm, and the inner diameter of the fixing tube 11 is 5-10 cm.

[0063] In some embodiments, a plant grid plate is disposed in the rectangular frame, which facilitates the growth of plant roots and can effectively help fix the soil and prevent soil erosion.

[0064] When it rains, the system further hinders the rapid falling of rainwater through the staggered rectangular frames, increases the time that rainwater stays in the rectangular frames, and thus allows more rainwater to enter the fixed cylinder. The rainwater enters the plants on the grid plate through the fixed cylinder, reducing soil loss while solving the problem of vegetation being prone to water shortage.
