Description

Technical Field

[0001] The invention relates to the technical field of garden engineering and garden greening, and in particular to a garden greening engineering slope structure. Background Art

[0002] With the continuous acceleration of urbanization and the increasing human activities, a large number of slopes that were originally in a natural state have been continuously developed and destroyed. This phenomenon has brought many serious consequences, causing the ecological environment to deteriorate sharply. In this context, the importance of slope greening has become increasingly prominent. Slope greening can effectively restore the original ecological function of the slope and greatly improve the stability of the ecosystem. Specifically, slope greening can play a key role in many aspects. First, it can significantly reduce soil erosion. When rain falls on the slope, the roots of green vegetation can hold the soil tightly to prevent the soil from being easily washed away by rain. Secondly, slope greening can also help purify the air. Vegetation absorbs carbon dioxide and releases oxygen through photosynthesis, providing fresh air for the surrounding environment. Thirdly, it can reduce noise. Green vegetation can absorb and reflect sound waves, reduce the spread of noise, and create a quieter living and working environment for people. In addition, slope greening can also regulate the climate. Vegetation releases water vapor through transpiration and regulates air humidity. At the same time, it can also absorb solar radiation and reduce the temperature of the surrounding environment.

[0003] At present, in garden projects, the greening of slopes usually adopts the method of planting green vegetation on the surface of the slope. This method can indeed prevent the soil on the slope surface from being washed away by rainwater to a certain extent. However, when the slope is washed by heavy rainwater, if the rainwater is not drained in time, serious problems will arise. The rainwater that is not drained in time will quickly infiltrate into the lower rock and soil of the slope, making the lower rock and soil of the slope oversaturated. Once the rock and soil is oversaturated, its shear strength will be greatly reduced. In this case, the slope structure will become extremely unstable, prone to geological disasters such as landslides and collapses, posing a huge threat to people's lives and property safety. Summary of the invention

[0004] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a slope structure for landscaping projects, which solves the technical problem that when the slope is eroded by heavy rain, the slope structure will become extremely unstable and prone to landslides, collapses, etc.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions: The slope structure of the landscaping project includes: a slope body, a water collecting anchor rod assembly, and a water collecting trough. The slope body is provided with: an anti-slip stabilization layer, an anti-seepage layer, and a planting layer in sequence from the inside to the outside. The slope body includes: a slope top and a slope foot. The slope top and the slope foot are respectively located at the upper and lower ends of the slope body. The water collecting trough is arranged at the slope foot. The water collecting trough is arranged along the extension direction of the slope body. The water collecting anchor rod assembly array is buried in the slope body. The water collecting anchor rod assembly includes: a riser, a water collecting hopper, and a filter body. The water collecting hopper is installed at the upper end of the riser. The filter body is arranged in the water collecting hopper. The upper end of the water collecting hopper is coplanar with the upper end surface of the anti-seepage layer, and the lower end of the riser is connected to the water collecting trough.

[0006] Based on the above structure, the principle of the slope structure of the landscaping project is as follows: the water-collecting anchor rod assembly is used to collect rainwater in the planting layer to prevent rainwater that has infiltrated into the planting layer from continuing to infiltrate in the slope, causing the weight of the rock and soil to increase, the rock and soil to be softened, and the shear strength of the rock and soil to be reduced, resulting in instability, landslides, and collapse of the slope structure. At the same time, rainwater may also form dynamic water pressure in the slope, pushing the rock and soil to slide down; the water-collecting anchor rod assembly also serves as a ground anchor to anchor the anti-slip stabilization layer and the anti-seepage layer on the slope, thereby increasing the overall stability of the slope structure; the anti-slip stabilization layer serves as a transition layer between the anti-seepage layer and the original rock and soil of the slope in this structure, alleviating the stress concentration caused by the difference in material properties between the two, and preventing damage caused by excessive stress between the two; the water collection trough is connected to the lower end of the riser, and is used to promptly discharge the rainwater collected by the water-collecting anchor rod assembly; the design of the anti-seepage layer prevents rainwater from infiltrating into the deep layer of the slope.

[0007] Furthermore, in the slope structure of the landscaping project in the present application, the anti-slip stabilization layer includes: a first geosynthetic structure layer and a second geosynthetic structure layer, wherein the first geosynthetic structure layer is covered on the slope body and arranged along the extension direction of the slope body, and the second geosynthetic structure layer is covered on the first geosynthetic structure layer. As a preferred embodiment of the present application, in the slope structure of the landscaping project of the present invention, the first geosynthetic structure layer is arranged on the slope body, tightly fitting with the upper end face of the slope body, providing a preliminary reinforcement effect for the slope body; the first geosynthetic structure layer is arranged along the extension direction of the slope body to ensure the comprehensiveness and continuity of the coverage; the second geosynthetic structure layer is covered on the first geosynthetic structure layer, and the second geosynthetic structure layer cooperates with the first geosynthetic structure layer to further enhance the performance of the overall structure, which not only improves the tensile strength of the first geosynthetic structure layer, but also, as the first geosynthetic, the second geosynthetic structure layer The protective layer of the structural layer works synergistically with the first geosynthetic structure layer to enhance the durability of the first geosynthetic structure layer; before laying the first geosynthetic structure layer, first, the surface of the slope body is cleaned and leveled to ensure that there are no sharp objects and obstacles to ensure that the first geosynthetic structure layer can be well covered on the slope body. When laying the first geosynthetic structure layer, the fit between the first geosynthetic structure layer and the slope body is ensured to avoid wrinkles or gaps; then, the second geosynthetic structure layer is laid on the first geosynthetic structure layer, and the flatness and tightness of the second geosynthetic structure layer and the first geosynthetic structure layer are also ensured.

[0008] Furthermore, in the slope structure of the landscaping project in the present application, a group of ramps are provided between the top and the foot of the slope, one group of the ramps are arranged at intervals on the slope body, and one group of the ramps are arranged along the extension direction of the slope body. As a preferred embodiment of the present application, the ramps in the slope structure of the landscaping project of the present invention are used to divide the slope body into several shorter slope sections, reduce the height and slope of each slope section on both sides of the ramps, thereby reducing the downward force of the slope body; when rainwater scours, the ramps make the flow path of rainwater on the slope surface tortuous, prolong the flow time of rainwater on the slope surface, thereby reducing the flow speed of rainwater and reducing the scouring force of rainwater on the slope surface; the design of multiple ramps requires the diversion and guidance of rainwater through multiple ramps, which can disperse the energy of rainwater and reduce the scouring destructive force of rainwater on the slope surface. The diversion of rainwater can make the distribution of rainwater on the slope surface more uniform and reduce local concentrated scouring.

[0009] Furthermore, in the slope structure of the landscaping project in the present application, a group of the slope platforms are provided with transverse drainage ditches, the transverse drainage ditches are arranged along the extension direction of the slope platforms, a group of longitudinal drainage ditches are arranged between adjacent slope platforms, a group of longitudinal drainage ditches are extended in the inclination direction of the slope body, the two ends of the longitudinal drainage ditches are respectively connected with two adjacent transverse drainage ditches, and a group of longitudinal drainage ditches are connected with the water collection tank. As a preferred embodiment of the present application, the transverse drainage ditches and longitudinal drainage ditches in the slope structure of the landscaping project of the present invention will collect a large amount of rainwater on the surface of the slope body during rainfall, and the transverse drainage ditches and longitudinal drainage ditches can quickly collect and guide the rainwater to avoid the accumulation of rainwater on the surface of the slope body, thereby reducing the soaking and erosion of the slope surface by rainwater, and reducing the risk of geological disasters such as landslides and mud-rock flows.

[0010] Furthermore, in the slope structure of the landscaping project in the present application, the water collection anchor assembly is arranged between a pair of adjacent drainage transverse grooves, and the water collection anchor assembly is arranged between a pair of adjacent drainage longitudinal grooves. As a preferred embodiment of the present application, the water collection anchor assembly in the slope structure of the landscaping project of the present invention is centrally arranged between a pair of adjacent drainage transverse grooves and a pair of drainage longitudinal grooves. Such a design facilitates the rainwater in the planting layer to be quickly and evenly collected by the water collection anchor assembly, thereby ensuring the structural stability of the planting layer.

[0011] Furthermore, in the slope structure of the landscaping project in the present application, the filter body includes: a first filter layer, a second filter layer, and a third filter layer. The first filter layer is arranged in the water collecting bucket, and the second filter layer and the third filter layer are arranged on the first filter layer in sequence. The third filter layer, the second filter layer, and the first filter layer are arranged in sequence from coarse to fine in the vertical direction. As a preferred embodiment of the present application, the filter body in the slope structure of the landscaping project of the present invention is used to filter rainwater that infiltrates into the planting layer. The third filter layer is used to filter out larger particles of dust, mud, etc. The subsequent second filter layer and the first filter layer can further remove finer particles, thereby greatly improving the overall filtering accuracy and ensuring the final output of rainwater; the design of the multi-layer filter layer, through the synergistic effect of different levels, even if a certain degree of problem occurs in a certain layer, other layers can continue to play a filtering role, thereby ensuring the stability and reliability of the filtering effect. Since each layer of filter media shares the filtering task, the filtering burden of a single layer is reduced, thereby extending the service life of the entire filtering system.

[0012] Furthermore, in the slope structure of the landscaping project in the present application, the side wall of the water collecting trough near the slope body is arranged higher than the upper end of the planting layer. As a preferred embodiment of the present application, in the slope structure of the landscaping project of the present invention, the side wall of the water collecting trough near the slope body is arranged higher than the upper end of the planting layer. Such a design is conducive to enabling the water collecting trough to effectively withstand the pressure of the rock and soil body from the slope body, preventing the rock and soil body from sliding and collapsing due to its own gravity or external loads; and limiting the displacement of the planting layer in the direction of the slope body's inclination angle to effectively control the deformation of the slope body.

[0013] Furthermore, the slope structure of the landscaping project in the present application also includes: a sump, the sump is arranged at the foot of the slope, the sump is connected to the sump, and the bottom of the sump is arranged lower than the bottom of the sump. As a preferred embodiment of the present application, the sump in the slope structure of the landscaping project of the present invention is used to store and collect rainwater; the bottom of the sump is lower than the bottom of the sump, and such a design can use gravity to make water flow into the sump more smoothly.

[0014] It can be seen from the above technical solution that the present invention has the following beneficial effects: The present invention provides a slope structure for a garden greening project, which uses an anti-seepage layer arranged on the slope to block rainwater in the planting layer and prevent the rainwater in the planting layer from penetrating into the deep rock and soil of the slope. The water-collecting anchor rod assembly is used to collect rainwater in the planting layer and drain the planting layer in time to avoid over-saturation of the rock and soil in the planting layer, which would reduce the shear strength of the planting layer and cause the sliding of the planting layer.
