Description

Technical Field

[0001] This utility model relates to the field of highway slope protection technology, and more specifically, to a novel ecological highway slope skeleton protection structure. Background Technology

[0002] During the construction of infrastructure projects such as highways, the destruction of original vegetation is inevitable. Excavation, including the disposal of excavated soil and rocks, leaves numerous exposed slopes in the otherwise harmonious natural environment. These slopes can be rocky or earthen, and can be steep or gentle. According to the principles of restoration ecology, earthen slopes have the capacity for self-repair and recovery when environmental disturbances are eliminated. However, this is a lengthy process, subject to many uncertainties due to environmental changes, and cannot achieve timely protection and greening effects. Rock slopes, lacking the conditions for vegetation growth, are even more difficult to self-recover.

[0003] Therefore, only artificial means can accelerate the recovery process. Using vegetation to stabilize slopes and improve the ecological environment is ecologically termed slope ecological protection. In engineering practice, techniques such as hydroseeding and netting are commonly used for protection to achieve the effect of slope revegetation.

[0004] Currently, hydroseeding and netting techniques are commonly used for slope ecological restoration in engineering projects. However, existing ecological protection technologies often only focus on the initial survival rate of plants, failing to fully consider the long-term ecological competition and environmental adaptability of plants. Extensive practice shows that while many slopes show good initial vegetation restoration after protection construction, over time, due to vicious competition among plants or the inability of the external environment to meet their ecological needs, plant growth gradually weakens, community succession reverses, ultimately leading to vegetation degradation, renewed soil exposure, and soil erosion.

[0005] To achieve sustainable and permanent ecological protection, it is essential to apply ecological principles and construct a harmonious, orderly, and stable plant community tailored to local conditions. Therefore, this invention proposes a novel ecological slope protection structure for highways that integrates structural stability, efficient drainage, and a superior habitat. Utility Model Content

[0006] This utility model provides a novel ecological slope protection structure for highways, which effectively improves the mechanical stability and drainage capacity of the slope, while providing a long-term stable growth environment for plant communities, thus achieving lasting ecological protection effectiveness.

[0007] According to one aspect of this utility model, a novel ecological highway slope skeleton protection structure is provided, comprising a platform drainage ditch, a slope rapid flow channel, and a skeleton. The platform drainage ditch is located at the top and bottom of the ecological highway slope. The skeleton is laid on the ecological highway slope. The skeleton includes vertical ribs and herringbone-shaped diagonal ribs. The diagonal ribs are arranged between two vertical ribs and spaced apart along the length of the vertical ribs. Anchor rods for connecting the diagonal ribs and the vertical ribs are provided at the connection points with the ecological highway slope. The slope rapid flow channel is laid on the ecological highway slope parallel to the vertical ribs. The vertical ribs and the diagonal ribs form a mesh structure, and a three-dimensional mesh mat for planting vegetation is laid within it.

[0008] Based on the above scheme, the preferred option is that the vertical ribs and the diagonal ribs are cast as a single piece.

[0009] Based on the above scheme, the preferred option is that the anchor rod is a threaded rod, and the anchoring section of the threaded rod extends deep into the slope layer.

[0010] Based on the above scheme, the angle between the inclined rib and the horizontal plane is preferably 45 degrees.

[0011] Based on the above scheme, the top and bottom of the ecological highway slope are respectively solidified with concrete to form a solidification layer, and a sedimentation well is set at the bottom of the ecological highway slope.

[0012] Based on the above scheme, the preferred option is that the spacing between the oblique ribs is 300mm.

[0013] Based on the above scheme, preferably, the cross-section of the vertical rib is U-shaped, and the cross-section of the sloping rapid flow channel is U-shaped, and is set at the bottom of the vertical rib.

[0014] Based on the above scheme, the preferred embodiment is that the three-dimensional mesh mat includes, from bottom to top, a non-woven fabric mat, a seed mat, a first mesh mat, a coconut fiber mat, and a second mesh mat, and a coconut shell fiber mesh is attached to the surface of the second mesh mat.

[0015] Preferably, based on the above scheme, the seed pad includes a top paper and a bottom paper, and the top paper is laminated to the seed surface by applying an adhesive to the surface of the bottom paper and scattering seeds at regular intervals.

[0016] This invention discloses a novel ecological slope protection structure for highways. By employing a mesh-like framework composed of vertical and diagonal ribs, combined with slope runoff channels and platform drainage ditches, a complete slope protection and drainage system is constructed. This structure significantly optimizes the drainage performance of the ecological slope, effectively preventing slope instability and soil erosion caused by excessive rainwater infiltration. Simultaneously, the integrated framework and deep anchoring technology greatly enhance the slope's mechanical stability. The internally laid composite three-dimensional mesh provides an ideal habitat for plant growth, offering water and fertilizer retention and structural stability, which is conducive to the formation and stability of diverse plant communities. Ultimately, this achieves long-term, efficient, and unified slope protection and ecological restoration. Attached Figure Description

[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0025] Please see Figure 1 and combined Figure 2 and Figure 3 As shown, this utility model provides a novel ecological slope skeleton protection structure for highways, which is mainly applied to ecological slopes 1.

[0026] This utility model discloses a novel ecological slope protection structure for highways, comprising a platform drainage ditch 2. The platform drainage ditch 2 is located at the top and bottom of the ecological slope 1, serving to collect and divert water flow from the slope top and roadbed, preventing water from overflowing along the slope surface and seeping into the deep soil, thus reducing the gripping force of the anchoring sections of the anchor rods 5 and weakening the anti-sliding effect of the anchor rods 5 and the framework 4. The ditch has a reasonable longitudinal slope to guide water to the regional drainage network, reducing the amount of water collected on the slope from the source and easing the burden on subsequent slope drainage.

[0027] This utility model discloses a novel ecological slope protection structure for highways, which also includes a frame 4. The frame 4 comprises vertical ribs 41 and diagonal ribs 42. The diagonal ribs 42 are arranged in a "V" shape between the two vertical ribs 41, forming a regular arrow-shaped open mesh structure. The spaces are first cleared of gravel and backfilled with improved soil, then planted with mixed grass seeds. Water collection seams are left at the edges to guide rainwater to the vertical ribs 41. This divides the large slope into small units to distribute the load and buffer minor soil deformations, thereby strengthening engineering protection. Planting grass compensates for the ecological shortcomings of traditional frames, allowing the slope to blend with the surrounding natural environment, enhancing visual comfort, and meeting the needs of ecological landscape design.

[0028] Preferably, the vertical rib 41 and the diagonal rib 42 are integrally cast in place using C25 concrete to form a well-integrated mesh support system. Furthermore, the angle between the diagonal rib 42 and the horizontal plane is 45 degrees. This angle adapts to the slope gradient, making the stress more closely aligned with the direction of the resultant earth pressure, guiding rainwater to flow smoothly towards the vertical rib drainage channel, and simultaneously ensuring balanced stress at the joint between the diagonal rib 42 and the vertical rib 41.

[0029] An anchor rod 5 is installed at each connection node between the diagonal rib 42 and the vertical rib 41. The anchor rod 5 is made of threaded steel, and its anchoring section is driven into the deep rock and soil of the slope at a certain angle. The exposed top end of the anchor rod 5 is directly embedded in the concrete of the frame 4, and is cast as a whole with the vertical rib 41 and the diagonal rib 42 to ensure direct force transmission and ensure that the entire frame 4 is firmly connected to the slope surface.

[0030] It should be noted that the vertical ribs 41 and the inclined ribs 42 of this utility model first divide the slope load through the frame structure, and concentrate the dispersed load to the top node of the rib; at this time, the anchor rod 5 uses the friction and gripping force between the anchor section and the deep soil and rock to pull down and anchor the load at the node to the stable layer, so as to prevent the skeleton 4 from cracking or displacing due to the concentrated load. Especially for steep slopes, the anchor rod 5 can be matched with the angle of the inclined rib 42 to further balance the direction of the resultant force of the earth pressure and reduce the bending deformation of the inclined rib 42. At the same time, the frame constraint of the skeleton 4 can also limit the loose sliding of the soil around the anchor rod 5, and prevent the anchor rod 5 from losing its anchoring function due to soil instability. The two form a two-way synergy, which greatly improves the slope's anti-sliding and anti-cracking ability and is suitable for the protection needs of loose slopes such as weathered granite soil and residual slope soil.

[0031] Furthermore, the slope runoff channel 3 of this invention is arranged parallel to the vertical ribs 41 for rapidly discharging slope runoff. Please continue to combine Figure 3 As shown, the cross-section of the vertical rib 41 of this utility model is designed in a U-shape to achieve its purpose of lateral airflow guidance.

[0032] The slope trough 3 has a concave cross-section and is positioned at the bottom of the vertical rib 41. This integrated design ensures the structural integrity of the vertical rib 41 while significantly alleviating the pressure of water drainage at the top of the slope, saving space, and improving structural efficiency. Rainwater is guided by the platform drainage ditch or along the herringbone rib 42 and naturally converges towards the vertical rib 41 under gravity.

[0033] To facilitate personnel access to and from the slope, regularly clean impurities from the vertical rib drainage channels, unclog blockages in the rapid flow channels, and check the unobstructed flow of the platform drainage ditches, ensuring the long-term effective operation of the drainage system, this utility model also incorporates steps within the vertical ribs 41. These steps not only provide a safe and convenient operating path for maintenance but also serve as an "auxiliary diversion" mechanism. The concrete structure embedded in the steps slightly blocks some of the overflowing rainwater, guiding it towards the vertical rib drainage channels. Simultaneously, it prevents personnel from trampling on the slope surface and damaging the vegetation and drainage components, indirectly protecting the integrity of the drainage system.

[0034] Preferably, this utility model sets a sedimentation well at intervals at the bottom of the ecological slope of the highway. By using the principle of gravity sedimentation, the water flow is slowed down by utilizing the space of the well, allowing the impurities such as mud, gravel, and dead branches carried by rainwater to be naturally deposited at the bottom of the well. This prevents impurities from entering the downstream drainage components with the water flow and causing blockage or wear. At the same time, it facilitates centralized dredging in the later stage and ensures the long-term smooth operation of the drainage system.

[0035] Within each grid formed by the skeleton 4, a composite three-dimensional mesh 6 is laid. For example... Figure 4 As shown, the three-dimensional mesh mat 6 comprises, from bottom to top: a non-woven fabric mat 61, a seed mat 62, a first mesh mat 63, a coconut fiber mat 64, and a second mesh mat 65. A natural coconut fiber mesh is also attached to the surface of the second mesh mat 65. The non-woven fabric mat 61 acts as a filter to prevent soil erosion; the seed mat 62, coconut fiber mat 64, and coconut fiber mesh together form a water-retaining, heat-insulating, and breathable growth layer; the multi-layered mesh mat provides strong reinforcement and soil stabilization functions.

[0036] The seed pad 62 of this invention is composed of a base paper and a top paper. Seeds are fixed to the base paper at regular intervals with adhesive and then covered by the top paper. This factory-prefabricated seed pad ensures uniform distribution and accurate sowing of plant seeds, which is conducive to the formation of a uniform and stable plant community.

[0037] During construction, the ecological slope of the highway was first trimmed, and then concrete was poured at the top and bottom of the slope to form a solidification layer. A sedimentation well 8 was set up at the bottom of the slope. Subsequently, surveying and setting out were carried out, trenches for the framework 4 and the slope flow channel 3 were excavated, anchor rods 5 were installed and steel bars were tied, and finally, formwork was erected and concrete was poured to form the framework 4. After the framework 4 was cured, a three-dimensional mesh mat 6 was laid within its grid and necessary maintenance was carried out until the plant community was stable and growing.

[0038] This utility model effectively solves key problems in traditional slope ecological protection, such as insufficient stability, poor drainage, and community degradation, by integrating structural, drainage, and ecological technologies, and achieves long-term synergy between highway slope safety and ecological health.

[0039] Finally, the method described in this application is merely a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
