Description

Technical Field

[0001] This application relates to the field of geomorphological restoration engineering technology, and in particular to a method for treating erosion gullies. Background Technology

[0002] Geomorphological restoration is an important part of ecological restoration. It refers to the use of various technologies and restoration methods to repair damaged landforms in order to restore the damaged ecosystems (including animals, plants, terrain environment and soil structure) on the original landforms, and enable the damaged areas to achieve a virtuous cycle of overall coordination, self-sustaining and self-evolution.

[0003] Slopes subjected to long-term erosion by non-natural water flows (illegal human-caused drainage, such as industrial wastewater and domestic sewage) will form erosion gullies on the slope surface. As these non-natural water flows continue to erode, the soil on the slope will be continuously eroded, causing increasingly serious soil erosion. In the process of landform restoration and management, it is necessary not only to reasonably divert and drain the water flow, but also to repair the erosion gullies formed by erosion.

[0004] Traditional methods for repairing gullies are as follows: First, the gully is backfilled with soil (hereinafter referred to as "filling soil"). After the backfilled soil in the gully has settled and stabilized, green plants with well-developed root systems and fast growth (hereinafter referred to as "soil-stabilizing plants") are planted in the backfilled soil. As the roots of the soil-stabilizing plants continue to grow, their roots extend from the filling soil into the original soil, thereby strengthening the integrity of the filling soil and the original soil.

[0005] The planting of soil for soil stabilization and greening was carried out after the backfilled soil in the erosion gully had settled and stabilized, which to some extent restricted the construction period of the erosion gully landform restoration project. Summary of the Invention

[0006] In order to shorten the construction period for the restoration of erosion gully landforms, this application provides a method for erosion gully treatment.

[0007] This application provides a method for treating erosion gullies, which adopts the following technical solution:

[0008] A method for treating erosion gullies includes the following steps:

[0009] S1. Clean up the highly weathered gravel on the surface of the erosion gully;

[0010] S2. Measure and lay out the cleaned erosion gullies, calculate the volume of soil lost from the erosion gullies, and take samples of the soil from the cleaned erosion gullies for analysis, and cultivate filling soil with the corresponding volume and composition.

[0011] S3. Use soil with the same composition as the above-mentioned cultivation to cultivate soil-stabilizing green plants;

[0012] S4. Install a protective plate on the outside of the erosion ditch, fill the space between the protective plate and the inner wall of the erosion ditch with filling soil, and plant soil-stabilizing plants on the top and exposed sides of the filling soil.

[0013] S5. Observe the growth of the soil-stabilizing green plants. After the soil-stabilizing green plants survive and their roots extend into the original soil of the erosion ditch, remove the protective board.

[0014] S6. Lay eco-bags containing soil and plant seeds on the slope of the erosion gully.

[0015] Using the above technical solution, operators install protective boards on the outside of the erosion gully, fill the space between the protective boards and the erosion gully with pre-cultivated soil, and plant soil-stabilizing plants on the top and sides of the filled soil. Therefore, the settlement of the soil filled in the erosion gully and the root development of the soil-stabilizing plants can be carried out simultaneously. Compared with the traditional treatment method of waiting for the filling soil to settle before planting greenery, this effectively shortens the construction period for the restoration of the erosion gully landform.

[0016] When installing the protective panels, the operators attach them to the slope where the erosion gully is located. The protective panels reduce the possibility of the filled soil separating from the erosion gully. Once the roots of the soil-stabilizing plants extend into the original soil, it means that the roots of the soil-stabilizing plants have a certain anchoring effect on the filled soil. At this point, the protective panels are removed so that the operators can reuse them.

[0017] In a preferred embodiment, the present application may be further configured as follows: a protective net is installed on the back of the protective plate, a through groove is formed on the protective plate in the horizontal direction, a sliding groove is formed on the protective plate in the vertical direction, the sliding groove and the through groove are interconnected, a plurality of unit plates are slidably arranged in the sliding groove, and the unit plates are provided with through holes for soil-fixing plants to extend out.

[0018] Using the above technical solution, after the operator installs the mounting plate on the outside of the erosion gully, pre-cultivated soil is filled between the protective plate and the erosion gully. The filling soil reduces the amount of soil falling down the slope under the temporary obstruction of the protective plate and protective net.

[0019] After the soil filling is completed, insert the unit board into the sliding groove from top to bottom, so that the groove is closed by the unit board. Then, drill planting holes into the filling soil through the through holes (part of the protective netting can be cut off as needed to facilitate the planting of stronger soil-stabilizing plants). Finally, put the soil-stabilizing plants through the through holes into the planting holes, and backfill the planting holes with filling soil to complete the planting of soil-stabilizing plants.

[0020] In a preferred embodiment, the present application may be further configured such that: the unit plate includes an upper plate and a lower plate, and semi-circular grooves are formed on the sidewalls of the upper plate and the lower plate that are close to each other, and the semi-circular grooves of the upper plate and the lower plate form the through hole.

[0021] Using the above technical solution, the operator first installs the lower layer board into the installation plate from top to bottom, then plants the soil-stabilizing greenery. Next, the upper layer board is installed into the installation plate from top to bottom to form a through hole, so that the main stem of the soil-stabilizing greenery is in the through hole. This process of installing the lower layer board, planting the soil-stabilizing greenery, and installing the upper layer board is repeated to complete the planting of greenery on the side of the soil filling.

[0022] In a preferred embodiment, this application can be further configured as follows: a support plate is installed on the lower plate, the support plate has a groove for supporting the main trunk of the soil-stabilizing green plant, an arc-shaped rod is fixedly connected to the support plate, an arc-shaped groove is provided on the lower plate, the arc-shaped rod is slidably disposed in the arc-shaped groove, and a fixing mechanism for fixing the arc-shaped rod is provided on the lower plate.

[0023] With the above technical solution, after the operator completes the planting of soil-stabilizing plants, the operator slides the arc-shaped rod according to the actual slope inclination angle to change the inclination angle of the support plate, so that the main stem of the soil-stabilizing plants can fit into the inner wall of the groove. In this way, the main stem of the soil-stabilizing plants is supported by the support plate, reducing the possibility of the free end of the soil-stabilizing plants drooping.

[0024] In a preferred embodiment, the present application may be further configured as follows: the fixing mechanism includes a bolt and a nut, the bolt and the nut are threaded together, the arc-shaped rod is provided with a plurality of fixing holes for the bolt to pass through, the lower plate is provided with a connecting lug, and the connecting lug is provided with a fixing hole for the bolt to pass through.

[0025] With the above technical solution, after the operator completes the sliding adjustment of the arc rod, the bolt is inserted into the fixing hole one and fixing hole two, and the nut is threaded onto the bolt. In this way, the possibility of the arc rod sliding in the arc groove is reduced by the obstruction of the bolt, and the support plate can be maintained at the ideal tilt angle.

[0026] In a preferred embodiment, this application may be further configured such that: an extension rod is rotatably mounted on the protective plate, an anchor rod is rotatably mounted on the extension rod, a sliding hole is provided on the anchor rod, an anchor spike is slidably disposed in the sliding hole, and a driving assembly is provided inside the anchor rod, the driving assembly being used to drive the anchor spike to extend beyond the anchor rod.

[0027] Using the above technical solution, the operator rotates the extension rod and the anchor rod to insert the anchor rod into the soil on both sides of the erosion gully. Then, the driving component drives the anchor spike to extend beyond the anchor rod. Under the anchoring effect of the anchor rod and the anchor spike, the possibility of the protective plate slipping off the slope is reduced, thereby improving the stability of the protective plate.

[0028] In a preferred embodiment, the present application may be further configured such that: the drive assembly includes a lead screw, a drive block, and a connecting rod; the lead screw is rotatably disposed within the anchor rod; the drive block is threadedly engaged with the lead screw; the drive block is slidably disposed within the anchor rod; one end of the connecting rod is hinged to the drive block; and the other end of the connecting rod is hinged to the anchor spike.

[0029] With the above technical solution, after the operator inserts the anchor rod into the soil, he rotates the screw, which drives the drive block to move closer to the anchor spike. The drive block pushes the anchor spike into the soil through the connecting rod, thereby enabling the anchor spike to perform its anchoring function.

[0030] Conversely, by rotating the screw in the opposite direction, the operator drives the drive block to move away from the anchor spike. The drive block, through the connecting rod, causes the anchor spike to retract into the anchor rod, so that the operator can pull the anchor rod out of the soil and remove the protective plate.

[0031] In a preferred embodiment, this application may be further configured such that: the protective plate has a receiving groove for accommodating the extension rod, the extension rod is rotatably installed in the receiving groove, and the extension rod has a cavity for accommodating the anchor rod, the anchor rod is rotatably installed in the cavity.

[0032] With the above technical solution, after the operator pulls the anchor rod out of the soil, the anchor rod is rotated so that it is housed in the cavity of the extension rod. Then the extension rod is rotated so that both the extension rod and the anchor rod are housed in the receiving groove. In this way, during the handling of the protective plate, not only is the possibility of damage to the anchor rod and the extension rod reduced, but the space occupied by the equipment is also reduced.

[0033] In a preferred embodiment, this application may be further configured such that: a plug rod is installed on the protective plate, a first plug hole is provided on the protective plate for inserting the plug rod, and a second plug hole is provided on the extension rod for inserting the plug rod.

[0034] Using the above technical solution, the operator inserts the rod through the first and second insertion holes in sequence. On the one hand, the anchoring effect of the rod further improves the stability of the protective plate installation. On the other hand, the obstruction effect of the rod reduces the possibility of the extension rod rotating.

[0035] In a preferred embodiment, the present application may be further configured such that: the insert rod includes a base rod and a plurality of unit rods, the top of the base rod and the top of each unit rod are provided with a protrusion, the protrusion and the bottom of the unit rod are threaded together.

[0036] With the above technical solution, both the base rod and the unit rod are connected to the adjacent unit rod through raised threads. Therefore, the operator can increase the number of unit rods according to actual needs, so that the insertion rod has sufficient length, so that the insertion rod can be inserted into the soil at the bottom of the slope.

[0037] In summary, this application includes the following beneficial technical effects:

[0038] 1. The gully erosion control method described in this application allows for the simultaneous settlement of the filling soil and the root development of the soil-stabilizing vegetation. Compared with the traditional control method of waiting for the filling soil to settle before planting vegetation, this method effectively shortens the construction period for gully landform restoration.

[0039] 2. Operators can slide the arc-shaped rod according to the actual slope inclination angle to change the inclination angle of the support plate, so that the main stem of the soil-stabilizing green plant is attached to the inner wall of the groove. Under the support of the support plate, the possibility of the free end of the soil-stabilizing green plant drooping is reduced.

[0040] 3. By inserting anchor rods, anchor spikes, and stakes into the soil, the operators reduce the possibility of the protective panel slipping off the slope, thereby improving the stability of the protective panel. Attached Figure Description

[0050] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail.

[0051] This application discloses a method for treating erosion gullies.

[0052] The gully erosion control method disclosed in this application includes the following steps:

[0053] S1. Clean up the highly weathered gravel on the surface of the erosion gully;

[0054] S2. Measure and lay out the cleaned erosion gullies, calculate the volume of soil lost from the erosion gullies, and take samples of the soil from the cleaned erosion gullies for analysis, and cultivate filling soil with the corresponding volume and composition.

[0055] S3. Use soil with the same composition as the above-mentioned cultivation to cultivate soil-stabilizing green plants;

[0056] S4. Install protective board 1 on the outside of the erosion gully, fill the space between the protective board 1 and the inner wall of the erosion gully with filling soil, and plant soil-stabilizing green plants on the top and exposed sides of the filling soil.

[0057] S5. Observe the growth of the soil-stabilizing green plants. After the soil-stabilizing green plants survive and their roots extend into the original soil of the erosion ditch, remove the protective board 1.

[0058] S6. Lay eco-bags containing soil and plant seeds on the slope of the erosion gully.

[0059] Under the obstruction of the protective plate 1, the filling soil can continue to settle downwards. During the settling process of the filling soil, the root system of the soil-stabilizing green plants is also growing continuously. Therefore, in this gully erosion control method, the settling of the filling soil and the root development of the soil-stabilizing green plants can be carried out simultaneously. Compared with the traditional control method of waiting for the filling soil to settle before planting green plants, it effectively shortens the construction period of gully landform restoration.

[0060] After the roots of the soil-stabilizing plants extend into the original soil (the growth of the roots of the soil-stabilizing plants can be observed by using a control group of soil-stabilizing plants under the same conditions, for example, by placing soil under the same conditions in a transparent container, planting soil-stabilizing plants with similar growth, and cultivating them according to natural conditions), it signifies that the roots of the soil-stabilizing plants play a certain anchoring role in the filling soil. At this point, the protective board 1 is removed so that the operators can reuse the protective board 1.

[0061] See attached document Figure 1 and attached Figure 2 As shown, a protective net 11 is installed on the back of the protective plate 1 to reduce the loss of filling soil. Depending on the properties of the soil, the protective net 11 can be made of wire mesh or woven mesh. The protective net 11 can be installed on the back of the protective plate 1 with nails. Several through slots 12 are opened horizontally on the protective plate 1, and several sliding slots 13 are opened vertically on the protective plate 1. The sliding slots 13 and the corresponding through slots 12 are arranged in a one-to-one correspondence, and the sliding slots 13 and the corresponding through slots 12 are interconnected.

[0062] For the sake of brevity, only two through slots 12 are shown in the attached figures. Since the structure inside each through slot 12 is the same, only the relevant structure inside one of the through slots 12 will be described in detail below. The relevant structures inside the other through slots 12 will not be described here.

[0063] See attached document Figure 1 and attached Figure 2 As shown, several unit plates 2 are slidably installed in the sliding groove 13 along the vertical direction. Similarly, for the sake of simplicity in the attached drawings, only two unit plates 2 are shown in each sliding groove 13. The unit plates 2 are all vertically arranged, and several unit plates 2 are stacked in sequence along the vertical direction. The two adjacent unit plates 2 are set to abut against each other.

[0064] See attached document Figure 1 and attached Figure 3As shown, the unit board 2 includes an upper board 21 and a lower board 22 that abut against each other. Semicircular grooves 211 are formed on the sidewalls of both the upper and lower boards 22. These semicircular grooves 211 of the upper and lower boards 22 form a through hole 201, through which operators plant soil-stabilizing plants into the filling soil. The separate installation of the upper and lower boards 21 and 22 facilitates the placement of the plant roots into the filling soil. Specifically, the lower board 22 is installed first, then the main stem of the plant is placed in the semicircular groove 211, and finally the upper board 21 is installed, ensuring the plant's main stem is within the through hole 201.

[0065] When planting soil-stabilizing plants along the through hole 201 into the filling soil, the operator can, as needed, first cut the protective net 11 appropriately, then make holes in the filling soil to plant the soil-stabilizing plants, then place the roots of the soil-stabilizing plants into the filling soil, and finally backfill the holes and water and fertilize appropriately to ensure that the soil-stabilizing plants can grow quickly.

[0066] See attached document Figure 3 and attached Figure 4 As shown, a support plate 3 is installed on the lower plate 22. The top surface of the support plate 3 has an arc-shaped groove 31, which is used to support the main stem of the soil-stabilizing green plants. An arc-shaped rod 32 is fixedly connected to the bottom surface of the support plate 3. An arc-shaped groove 221 is opened in the lower plate 22. The arc-shaped groove 221 and the arc-shaped rod 32 fit together. The arc-shaped rod 32 is slidably set in the arc-shaped groove 221.

[0067] See attached document Figure 3 and attached Figure 4 As shown, the lower plate 22 is provided with a fixing mechanism 4 for fixing the arc-shaped rod 32. The fixing mechanism 4 includes a bolt 41 and a nut 42 that are threaded together. The arc-shaped rod 32 has several fixing holes 321 through it in the horizontal direction for the bolts 41 to pass through. The fixing holes 321 are evenly distributed along the length of the arc-shaped rod 32. The side wall of the lower plate 22 is fixedly connected to two connecting ears 222. The two connecting ears 222 are located on both sides of the arc-shaped rod 32. Each connecting ear 222 has a fixing hole 223 through it in the horizontal direction for the bolts 41 to pass through.

[0068] After planting the soil-stabilizing greenery, the operator slides the arc-shaped rod 32 according to the actual slope inclination angle to change the inclination angle of the support plate 3, so that the main stem of the soil-stabilizing greenery can fit against the inner wall of the groove 31. Then, the bolt 41 is inserted into the fixing hole 321 and the fixing hole 223, and the nut 42 is threaded onto the bolt 41. In this way, under the support of the support plate 3, the possibility of the free end of the soil-stabilizing greenery drooping is reduced.

[0069] See attached document Figure 1 Appendix Figure 5 and appendix Figure 6 As shown, the protective plate 1 has receiving grooves 14 on both sides, and two extension rods 5 are rotatably installed in each receiving groove 14. The two extension rods 5 can be simultaneously hidden and stored in the receiving groove 14. Each extension rod 5 has a cavity 51 on the side wall near the protective net 11. An anchor rod 6 is rotatably installed in the cavity 51. The anchor rod 6 can be hidden and stored in the corresponding cavity 51. The figure shows the extension rod 5 and the anchor rod 6 in the unfolded state. The end of the anchor rod 6 away from the extension rod 5 is pointed, which is convenient for insertion into the soil.

[0070] See attached document Figure 6 and attached Figure 7 As shown, the anchor rod 6 has two sliding holes 61, which are symmetrical about the axis of the anchor rod 6. An anchor spike 611 is slidably installed in each sliding hole 61 along the axis of the sliding hole 61.

[0071] See attached document Figure 6 and attached Figure 7 As shown, each anchor rod 6 is equipped with a drive assembly 7 for sliding the anchor spike 611. The drive assembly 7 includes a lead screw 71, a drive block 72, and a connecting rod 73. The lead screw 71 is rotatably mounted inside the anchor rod 6. The drive block 72 is threadedly engaged with the lead screw 71 and is slidably mounted inside the anchor rod 6. A guide rod 712 is fixedly connected inside the anchor rod 6, and the length direction of the guide rod 712 is consistent with the length direction of the lead screw 71. The drive block 72 is slidably mounted on the guide rod 712. A handwheel 711 is coaxially fixedly connected to the lead screw 71 for easy rotation. The handwheel 711 is located outside the anchor rod 6. One end of the connecting rod 73 is hinged to the drive block 72, and the other end of the connecting rod 73 is hinged to the anchor spike 611.

[0072] After the operator places the protective plate 1, the extension rod 5 is rotated outside the receiving groove 14, and the anchor rod 6 is rotated outside the cavity 51. Then the handwheel 711 is turned, which drives the lead screw 71 to rotate. The lead screw 71 drives the drive block 72 to move. The drive block 72 pushes the anchor spike 611 outward and into the soil through the connecting rod 73. Under the anchoring effect of the anchor rod 6 and the anchor spike 611, the possibility of the protective plate 1 sliding off the slope is reduced, thereby improving the stability of the protective plate 1.

[0073] When removing the protective plate 1, first turn the handwheel 711 in the opposite direction to drive the anchoring spike 611 into the anchoring rod 6, then pull the anchoring rod 6 out of the soil, and rotate the anchoring rod 6 and the extension rod 5 in sequence so that the anchoring rod 6 is housed in the extension rod 5, and both the anchoring rod 6 and the extension rod 5 are housed in the receiving cavity, reducing the possibility of damage to the anchoring rod 6 and the extension rod 5, and also reducing the space occupied by this equipment.

[0074] See attached document Figure 1 and attached Figure 5As shown, a rod 8 is installed on the protective plate 1. The protective plate 1 has a through-hole 201-15 for inserting the rod 8, extending from top to bottom. An extension rod 5 also has a through-hole 201-22 for inserting the rod 8. By inserting the rod 8 from top to bottom into the through-holes 201-1 and 201-2, the operator ensures the bottom of the rod 8 is embedded in the soil, further enhancing the stability of the protective plate 1. The extension rod 5, hindered by the rod 8, has a reduced likelihood of rotation.

[0075] See attached document Figure 1 and attached Figure 5 As shown, the insertion rod 8 is composed of a base rod 81 and several unit rods 82 connected sequentially. The base rod 81 is located at the bottom and has a pointed bottom. Both the top of the base rod 81 and the top of each unit rod 82 are provided with a protrusion 811, which is threaded into the bottom of the unit rod 82. The operator can increase the number of unit rods 82 as needed to ensure the insertion rod 8 has sufficient length for insertion into the soil.

[0076] The implementation principle of this embodiment is as follows: the operator places the pre-cultivated filling soil between the protective plate 1 and the erosion ditch, and plants soil-stabilizing green plants on the top and sides of the filling soil. Therefore, the settlement of the filling soil and the root growth of the soil-stabilizing green plants can be carried out simultaneously, which effectively shortens the construction period of the erosion ditch landform restoration project.

[0077] After the roots of the soil-stabilizing plants have penetrated into the original soil, the protective board 1 is removed so that the operators can reuse it.

[0078] The embodiments described in this specific implementation are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
