And soil reconstruction and vegetation restoration are synchronously completed.

Description

Technical Field

[0001] The utility model relates to the technical field of retaining walls or protective walls, in particular to an integrated soil reconstruction ecological retaining wall. Background Art

[0002] Various production activities such as mining and water conservancy construction will produce slopes with damaged soil. The original vegetation and soil on these slopes are removed before the production activities begin, and after the production activities end, the slopes are covered with imported soil (soil transported from other places as backfill).

[0003] The soil particles of the imported soil are almost completely separated and there is no plant root system to constrain them. If not protected, interference factors such as precipitation, animal activities, and wind will cause the imported soil to be lost quickly, and there will be no time to form a stable soil layer. To avoid this situation, the existing technology uses geobags or retaining walls to protect the slope, but these structures will affect the growth of vegetation. Even if auxiliary structures such as vegetation blankets are used to allow vegetation to grow against the wall, it is difficult for the roots to penetrate deep into the slope, so only some meadow plants can be planted, and the vegetation is easy to die without human care.

[0004] Gabion cages are wire cages that can be filled with stones to form gabion stone retaining walls. However, the life of the wires in gabions is limited, making gabion stone retaining walls unsuitable for long-term use; gabions can be used in overlapping ways, or only to block the bottom of the slope. Utility Model Content

[0005] The utility model provides an integrated soil reconstruction ecological retaining wall.

[0006] The technical problem to be solved is that the imported soil on the slope where the vegetation and soil are destroyed is easy to be lost, and the existing structure for preventing soil and water loss affects the growth of vegetation.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions: an integrated soil reconstruction ecological retaining wall, used for slope protection and soil reconstruction of slopes with damaged vegetation and soil, including a geotextile attached to the slope, a gabion cage inclined against the geotextile, and a filler filled in the gabion cage;

[0008] The filling material includes bottom mud, gravel, and caulking soil from bottom to top. Perennial vine seedlings are planted in the bottom mud. The surface of the gabion cage facing away from the slope is recorded as a climbing surface. The vine seedlings extend out of the gabion cage from the climbing surface. An insulating climbing frame is also provided on the climbing surface to provide an attachment point for the vine seedlings and prevent the vine seedlings from being scalded.

[0009] Furthermore, the heat-insulating climbing frame is formed by bundling discarded aluminum core wires, and the aluminum core wires are bundled on the climbing surface layer by layer, and each layer of aluminum core wires is bundled in a horizontal direction into a wave shape that bulges outward away from the climbing surface.

[0010] Furthermore, the gabion cage is divided into two layers, the lower layer of the gabion cage is filled with bottom mud and gravel, and the upper layer of the gabion cage is filled with caulking soil. The climbing surface of the upper layer of the gabion cage shrinks and approaches the slope direction.

[0011] Furthermore, the bottom mud is clay soil, the filling soil is loam, and the bottom of the gabion cage is arranged in a foundation trench.

[0012] Furthermore, the geotextile is arranged to extend from the bottom of the gabion cage, and then extends upward to wrap the bottom mud and is tied to the gabion cage.

[0013] Furthermore, the vine plant seedlings are kudzu, ivy, honeysuckle or parthenocissus.

[0014] Compared with the prior art, the integrated soil reconstruction ecological retaining wall of the utility model has the following beneficial effects:

[0015] In the utility model, the existing gabion stone retaining wall is transformed, some of the stones at the bottom are replaced with bottom mud, some of the stones at the top are replaced with caulking soil, large stones are replaced with gravel that has little impact on the root system, and vine seedlings are planted in the bottom mud. As time goes by, the caulking soil gradually seeps into the stones, forming a soil-stone mixed structure that is more stable than simple stones. At the same time, the vines climb all over the gabion stone retaining wall along the insulation climbing frame and their aerial roots penetrate into the soil-stone mixed structure, replacing the steel wire of the gabion cage to constrain the stones therein, so that the slope can exist stably for a long time, and simultaneously complete soil reconstruction and vegetation restoration.

[0020] like Figure 1-2 As shown, an integrated soil reconstruction ecological retaining wall is used for slope protection and soil reconstruction of a slope 7 where vegetation and soil are destroyed, comprising a geotextile 8 attached to the slope 7, a gabion cage 1 arranged obliquely against the geotextile 8, and a filler filled in the gabion cage 1;

[0021] The geotextile 8 here serves to prevent the foreign soil on the slope 7 from being disturbed and damaged during the construction of the ecological retaining wall.

[0022] The filling material includes bottom mud 3, gravel 4, and caulking soil 5 from bottom to top. The function of the bottom mud 3 is to collect water seeping from the gravel 4 and the slope 7 for the growth of vines and improve the survival rate. The gravel 4 is a small and smooth stone that has little effect on the plant root system. Over time, the caulking soil 5 and the foreign soil on the slope 7 will gradually infiltrate into the gravel 4 to form a soil-rock mixture, which can allow the aerial roots of the vines to penetrate.

[0023] Perennial vine seedlings 6 are planted in the bottom mud 3, and the surface of the gabion cage 1 facing away from the slope 7 is recorded as a climbing surface. The vine seedlings 6 extend out of the gabion cage 1 from the climbing surface. An insulating climbing frame 2 is also provided on the climbing surface to provide an attachment point for the vine seedlings 6 and prevent the vine seedlings 6 from being scalded.

[0024] Here, the heat-insulating climbing frame 2 not only provides an attachment point for the vines, ensuring that the vines with poor climbing ability can also climb and grow smoothly, but also prevents the vines from being scalded by the hot gabions 1 and gravels 4. Because in the early stage of the growth of the vines, the vegetation coverage on the climbing surface is very low, and the exposed gabions 1 and gravels 4 will be very hot.

[0025] like Figure 3 As shown, the heat-insulating climbing frame 2 is formed by bundling discarded aluminum core wires, which are bundled layer by layer on the climbing surface, and each layer of aluminum core wires is bundled horizontally into a wave shape that bulges outward away from the climbing surface.

[0026] Here, the heat-insulating climbing frame 2 is made of discarded aluminum core wires because the aluminum core wires themselves can play a role similar to that of a wire tie and can be tied to the gabion cage 1 by themselves without other fixed structures. In this embodiment, in the wave-like structure formed by the binding of the aluminum core wires, each trough position is wound around a steel wire of the gabion cage 1, and the binding can be completed quickly. Of course, if there are no discarded aluminum core wires, other discarded materials that are not easy to cause burns can also be used to make the heat-insulating climbing frame 2, such as horizontally tying some waste sticks on the gabion cage 1.

[0027] The gabion cage 1 is divided into two layers, the lower layer of the gabion cage 1 is filled with bottom mud 3 and gravel 4, and the upper layer of the gabion cage 1 is filled with caulking soil 5. The climbing surface of the upper layer of the gabion cage 1 shrinks and approaches the slope 7 direction.

[0028] The caulking soil 5 will gradually flow away. To prevent it from flowing to the ground, the container containing it needs to be slightly retracted to ensure that it flows downward. Note that the caulking soil 5 should be piled higher, higher than the gabion cage 1, to ensure that it still has a slope protection effect after flowing away.

[0029] In this embodiment, the bottom mud 3 is clay soil and the filling soil 5 is loam.

[0030] Here, the clay soil can be transformed from loam, so as to avoid preparing two kinds of soil at one time. The transformation method can be mixed with lime or bentonite mud abandoned on the construction site. The bottom of the gabion cage 1 is preferably set in the base groove to ensure stability and facilitate the rooting of the vine seedlings 6. The clay soil is preferably mixed with some soil water retaining agents such as polyvinyl alcohol.

[0031] The geotextile 8 is arranged to extend from the bottom of the gabion cage 1, and then extends upward to cover the bottom mud 3 and is tied to the gabion cage 1 to prevent the bottom mud 3 from flowing out. If the foundation trench is deep enough, the bottom mud 3 may not be covered.

[0032] The vine seedlings 6 are kudzu, ivy, honeysuckle or ground ivy. These are vines that are easy to grow aerial roots.

[0033] The utility model discloses an integrated soil reconstruction ecological retaining wall, and the use method thereof comprises the following steps:

[0034] Step 1: Lay the geotextile 8 and dig the foundation trench;

[0035] Step 2: Install the gabion cage 1 with the heat-insulating climbing frame 2;

[0036] Step 3: Pour bottom mud 3, gravel 4, and filling soil 5 into the gabion cage 1, and then wrap the bottom mud 3 with geotextile 8;

[0037] Step 4: Make holes in the geotextile 8, plant the vine seedlings 6, and tie them to the thermal insulation climbing frame 2.

[0038] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
