DETAILED DESCRIPTION

[0030] The technical scheme in the embodiment of the utility model will be described clearly and completely in combination with the drawings of the utility model.

[0031] Embodiment one

[0032] As Figure 1 And Figure 2The embodiment provides an assembled green slope protection structure, which comprises a plurality of splicable protection units, the protection units can form a large area by splicing, and the protection of slopes with different areas is met.

[0033] The protection unit comprises a grid layer 1 of a natural fiber net structure, a support layer 6 of a water permeable structure located below the grid layer 1, and an anchoring device for fixing the grid layer 1 and the support layer 6 to a slope surface; the grid layer 1 is distributed with a plurality of grids (for example, a structure of 4*4) in an array form, the grids are provided with grid holes 5 for planting plants, the support layer 6 is provided with through holes 15 corresponding to the grid holes 5; longitudinal drainage channels 2 are formed between left and right adjacent grids.

[0034] The grid layer 1 can adopt natural fiber nets such as coconut shell fiber and jute fiber, which are environment-friendly materials and can be naturally degraded over time, and is suitable for ecologically sensitive areas; the space in the grid layer 1 has good water permeability, allowing water to freely penetrate into the soil, avoiding slope collapse or landslide caused by water accumulation.

[0035] The support layer 6 is mainly composed of gravel, sand or environment-friendly synthetic materials, plays a role of rapid water permeation, prevents rainwater from accumulating on the slope body, forms a stable support framework through reasonable particle size grading, and can effectively disperse and bear the load of the upper structure. The water permeable support layer 6 can effectively penetrate water into the foundation, reduce the formation of surface runoff, and prevent local water accumulation or water flow from eroding the structure.

[0036] Plants are planted in the grid holes 5 to form ecological vegetation coverage, which covers the slope surface, and plants with developed root systems, drought tolerance or moisture tolerance and not easy to be damaged can be selected for planting; these vegetation not only has the effect of preventing soil erosion, but also can improve the landscape beauty of the slope body, promote soil and water conservation and ecological restoration; the root system of the plant penetrates into the soil like an "anchor", tightly combines the soil particles, and prevents the soil from being eroded and lost by water flow or wind force; the depth, distribution and density of the root system of different plants determine the reinforcement effect on the slope. The vegetation usually adopts a combination of multiple plants, which can form multi-level vegetation coverage and enhance the stability of the ecological system; common combinations include mixed planting of herbaceous plants, shrubs and trees to achieve the dual effects of short-term coverage and long-term soil fixation.

[0037] The grid layer 1 and the support layer 6 can be square; the grid structure can form a fixed frame on the slope surface, so that the soil particles are not easily washed away by rain; the channels between the grids allow rainwater to pass through, but slow down the water flow speed, preventing the formation of large-area runoff.

[0038] The size of each grid is the same, and each grid can be in a square structure; the edge of the grid has a raised blocking frame, so the longitudinal drainage channels 2 can be formed between the blocking frames. The left and right edges of the grid layer 1 can also be provided with raised blocking edges, and the grids close to the edges and the blocking edges also form longitudinal drainage channels 2.

[0039] In this embodiment, the slope protection structure can further include a flow guide plate, the longitudinal section of the flow guide plate is in the shape of "L", and the flow guide plate is connected to the lower end of the grid layer to form a transverse drainage channel 3 that communicates with the longitudinal drainage channel 2; the longitudinal drainage channel 2 and the transverse drainage channel 3 combine to form a slope drainage system, which is used to effectively drain water when it rains and underground water flows, and prevent landslides or structural instability caused by water accumulation; the slope drainage system effectively and timely drains excess water from the surface of the slope body to the bottom of the slope body, preventing rainwater from overflowing; the flow guide plate is made of a corrosion-resistant material to ensure the stability of the drainage and the stability of the slope body, and when the water flow is too large, the grid is used to assist in drainage, and the water in the lower longitudinal drainage channel 2 is drained through the transverse drainage channel 3.

[0040] In this embodiment, at least one of the grids is provided with a sensor mounting hole for mounting a first monitoring sensor 4, and the first monitoring sensor 4 is used to monitor the state of the slope body in real time and is connected to an external host computer. The first monitoring sensor 4 can be a temperature and humidity sensor and / or a displacement sensor, which can detect the displacement and deformation of the slope, detect the drainage condition, and timely warn of potential landslide or structural instability risk; when in use, a hole is drilled on the surface of the slope, the sensor is embedded, and cement or special glue is used for fixation.

[0041] In addition, the grid layer 1 and the support layer 6 can be riveted to the slope by a plurality of U-shaped rivets to improve the anti-sliding and anti-seismic ability of the slope body.

[0042] Embodiment Two

[0043] The assembled green ring protection slope structure provided in this embodiment can be further improved on the basis of the structure shown in Embodiment One, and therefore the same structure and principles between the two will not be described here.

[0044] The assembled green ring protection slope structure provided in this embodiment, as shown in Figures 3 to 5 The anchor device includes a plurality of anchor rods; the anchor rod includes an outer rod body with a hollow structure and an inner rod body 12 coaxially movably arranged in the outer rod body; the lower end of the inner rod body 12 is rotatably connected (for example, through a hinge 14) with a plurality of movable rods 10 uniformly arranged in the circumferential direction, and the lower end of the outer rod body is provided with a plurality of rod holes 16 corresponding to the movable rods 10 in the circumferential direction; the movable rods 10 are withdrawn (as shown in Figure 4 ) or extended (as shown in Figure 3 ) from the rod holes 16 with the up-and-down movement of the inner rod body 12.

[0045] The movable rod 10 connected to the lower end of the inner rod body 12 and the rod hole of the lower end of the outer rod body can be extended or retracted from the rod hole 16 when the movable rod 10 moves up and down, which is equivalent to a locking and releasing mechanism, which can increase the anchoring force when needed, or release the stress when the geological conditions change; in addition, since the movable rod 10 can be extended or retracted according to the movement of the inner rod body 12, this structure can adapt to the uneven deformation of the geology, reducing the risk of anchor rod fracture caused by geological changes.

[0046] In this embodiment, the anchor rod further comprises a knob 9 and an elastic return member 17 (such as a compression spring); the knob 9 is arranged above the inner rod body 12 and coaxially extends into the outer rod body 7 and is threadedly connected, and the elastic return member 17 is arranged below the inner rod body 12; when the knob 9 moves downward along the outer rod body 7, it pushes the inner rod body 12 to move downward against the elastic force of the elastic return member 17, and when the knob 9 moves upward along the outer rod body 7, the elastic return member 17 pushes the inner rod body 12 to move upward.

[0047] The knob 9 is arranged above the inner rod body 12 and coaxially extends into the outer rod body 7, and is connected with the inner rod body 12 through threaded connection, and the position of the inner rod body 12 can be quickly changed by rotating the knob 9; when the knob 9 is tightened, the inner rod body 12 is locked at a specific position, and due to the self-locking property of the thread, the inner rod body 12 will not slide even when subjected to external force, ensuring the stability of the anchor rod; the elastic return member 17 is arranged below the inner rod body 12, and its function is to push the inner rod body 12 to move upward by elastic force when the knob 9 moves upward, and to push the inner rod body 12 to move downward against the elastic force of the elastic return member 17 when the knob 9 moves downward; the elastic return member 17 provides a restoring force, so that the inner rod body 12 can automatically return to the preset position when the knob 9 is loosened, simplifying the installation and adjustment process of the anchor rod; this structure also reduces the dependence on external tools, and the operator can adjust the anchor rod by simply rotating the knob 9, reducing the labor intensity and operation difficulty.

[0048] In this embodiment, the bottom end of the outer rod body 7 is in a pointed structure, which is beneficial to reduce the drilling operation and directly insert the anchor rod into the stratum through the pointed head to achieve rapid anchoring; the upper part of the outer rod body 7 can be fixed with a sleeve with a baffle 11, which can be clamped on the surface of the slope protection structure to form a limit.

[0049] In this embodiment, the outer rod body 7 is provided with a second monitoring sensor 8 for monitoring the force state of the anchor rod in real time and being connectable with an external host computer. Real-time monitoring of the force state of the anchor rod is crucial for evaluating the stability and safety of the anchor rod. Through real-time data, potential structural problems can be found in time to prevent accidents; the second monitoring sensor can be based on a certain physical effect (such as strain, pressure, displacement, etc.) to monitor the force state of the anchor rod, and these sensors can convert the mechanical behavior (such as force, deformation) of the anchor rod into measurable electrical signals; the electrical signals collected by the sensors are amplified, filtered, and analog-to-digital converted (AD converted) after appropriate amplification, filtering, and analog-to-digital conversion, and can be transmitted to the host computer through wired or wireless means; the host computer can be a computer on site or a remote monitoring system, responsible for receiving, storing and analyzing these data.

[0050] The above is only an embodiment of the present application, and the specific structure and characteristics of the scheme known in the art are not described in detail. It should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
