Description

Technical Field

[0001] This utility model relates to the field of roadbed slope technology, and in particular to an integrated green protection structure for roadbed slopes. Background Technology

[0002] Roadbed slopes refer to the sloping surfaces on both sides of the roadbed cross section that connect to the ground. They are classified as embankment slopes and cutting slopes, and are a crucial factor affecting roadbed stability. The shape of slopes in roadbeds is often constructed as single slopes, broken lines, or stepped shapes. To prevent soil erosion and collapse of roadbed slopes, protective structures are needed to reinforce them.

[0003] As shown in the reference case "Overall Green Protection Structure for Roadbed Slope" (Announcement No. CN208251125U), a complete roadbed slope structure is formed by using new ecological grass mats as the main component and hollow hexagonal concrete blocks as the auxiliary component. Through overall slope planning and reasonable arrangement of procedures, the various elements of the slope are connected, thereby making the roadbed slope more stable and achieving the purpose of soil stabilization and moisture retention. The slope between the main road line and the first drainage ditch is subject to greater vibration, so precast hollow hexagonal concrete blocks are laid to ensure the stability of the slope in this area. Other slopes are constructed using environmentally friendly, low-cost, fast-construction ecological grass mats that are conducive to plant growth.

[0004] According to the above reference materials, the above-mentioned device involves excavating construction trenches for toe protection and water interception shoulder protection. The grass mat at the top of the slope is buried in the water interception shoulder protection trench, and the grass mat at the bottom of the slope is buried in the toe protection trench. Other parts are fixed with U-shaped nails. The hollow blocks should be crisscrossed, with tight interlocking between the blocks. The hollow blocks should be in close contact with the slope surface, and the gaps at the connection between the hollow blocks and the drainage channel should be filled with concrete. However, when this device is used to protect the roadbed slope, the hollow blocks and drainage channels are not ideal in terms of stabilizing soil and water loss. Water flow can easily erode the roadbed slope, affecting its stability. It is also inconvenient to effectively reinforce and drain the roadbed slope, thus reducing the service effectiveness of the roadbed slope. Utility Model Content

[0005] Therefore, it is necessary to provide an overall green protection structure for roadbed slopes to address the problem of inconvenience in effectively reinforcing and draining roadbed slopes.

[0006] The device includes a shoulder guard, with several evenly arranged mounting plates at the bottom of one end of the shoulder guard. A protective mechanism, capable of reinforcing the roadbed slope and guiding water flow, is located on both sides of the mounting plates. The protective mechanism includes several evenly arranged mounting grooves at the top of the mounting plates. A baffle is fixedly connected to one end of each mounting plate, and several evenly arranged drainage ditches are fixedly connected to one end of each shoulder guard. All drainage ditches are located on both sides of the mounting plates.

[0007] In one embodiment, the protective mechanism further includes a vegetation concrete layer fixedly connected to the bottom of the mounting plate, wherein a three-dimensional mesh is provided at the bottom of the vegetation concrete layer.

[0008] In one embodiment, the inner wall of the baffle is provided with a water guide groove, which is inclined to both sides.

[0009] In one embodiment, both sides of the water guide channel are located above the drainage ditch.

[0010] In one embodiment, the inner wall of the mounting groove is provided with a planting mat.

[0011] In one embodiment, a foot guard is fixedly connected to the lower part of the mounting plate, and the inner wall of the foot guard has several evenly arranged first drainage grooves.

[0012] In one embodiment, the top of the foot guard is aligned with the drain ditch.

[0013] In one embodiment, a second drainage groove is provided at the top of the shoulder pad.

[0014] Beneficial effects

[0015] 1. The above-mentioned overall green protection structure for roadbed slopes uses a three-dimensional net to intercept soil on the surface of the roadbed slope. Then, vegetation concrete is sprayed onto the three-dimensional net. The vegetation concrete achieves both safety protection and ecological planting. Multiple mounting plates are installed on the vegetation concrete, and planting mats can be placed in the mounting grooves. In conjunction with the vegetation concrete, vegetation can be planted and maintained. The baffles at the bottom of the mounting plates have an L-shaped structure, which can intercept the soil washed away on the roadbed slope. Excess water flow is guided by the water guide channels that slope to both sides. In conjunction with the drainage ditch, the water flow is guided and discharged, which can effectively reinforce and protect the roadbed slope and improve the protective stability of the structure.

[0016] 2. The toe protection at the bottom of the roadbed slope can improve the erosion resistance of the roadbed slope. In conjunction with the shoulder protection, it can protect the roadbed slope. The first drainage channel on the inner wall of the toe protection, together with the drainage ditch, can guide and discharge the water flow on the roadbed slope. The second drainage channel on the shoulder can intercept and guide the water flow on the roadbed slope, reduce the erosion of the roadbed slope, and improve the service effect of the roadbed slope.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The following is combined with Figure 1 - Figure 5 This invention describes the overall green protection structure for roadbed slopes.

[0027] In one embodiment, a roadbed slope integrated green protection structure includes a shoulder 100, with several evenly arranged mounting plates 200 at the bottom of one end of the shoulder 100, and a protection mechanism 300. The protection mechanism 300, which can reinforce the roadbed slope and guide water flow, is arranged on both sides of the mounting plates 200. The protection mechanism 300 includes several evenly arranged mounting grooves 310 opened at the top of the mounting plates 200, a baffle 320 is fixedly connected to one end of the mounting plates 200, and several evenly arranged drainage ditches 330 are fixedly connected to one end of the shoulder 100. The drainage ditches 330 are all arranged on both sides of the mounting plates 200.

[0028] It should be noted that the roadbed slope protection structure mainly consists of facing walls, retaining walls, frame slope protection, and vegetation protection.

[0029] Facing wall: made of mortar-grouted rubble or concrete, used to protect severely weathered or easily collapsible soil and broken rock slopes.

[0030] Retaining walls: used to support roadbed fill or hillside soil to prevent collapse.

[0031] Skeleton slope protection: The frame is constructed with concrete or masonry rubble and filled with grass. It has both structural reinforcement and ecological protection functions and is suitable for preventing slope collapse.

[0032] Vegetation protection: Slopes are stabilized by planting grass, laying turf, and planting trees, and the ecological protection effect is improved by combining technologies such as three-dimensional plant nets.

[0033] When protecting the roadbed slope, the protection mechanism 300, in conjunction with the vegetation concrete layer 340 and the three-dimensional mesh 350, can intercept and reinforce the sand and soil on the roadbed slope. The installation plate 200, through the installation groove 310, places the planting mat 370 to reinforce the roadbed slope. The baffle 320, in conjunction with the drainage ditch 330 and the toe guard 380, can guide and discharge water flow and reduce soil loss. The shoulder guard 100, through the second drainage ditch 382, ​​can intercept water flow on the roadbed slope, thus reinforcing the roadbed slope without affecting the normal use of the roadbed slope protection structure.

[0034] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the protective mechanism 300 also includes a vegetation concrete layer 340 fixedly connected to the bottom of the mounting plate 200. A three-dimensional mesh 350 is provided at the bottom of the vegetation concrete layer 340. A water guide channel 360 is provided on the inner wall of the baffle 320. The water guide channel 360 is inclined to both sides and both sides of the water guide channel 360 are provided above the drainage ditch 330. A planting mat 370 is provided on the inner wall of the mounting groove 310.

[0035] In this embodiment, the three-dimensional mesh 350 and the vegetation concrete layer 340 are sequentially installed on the roadbed slope. Multiple mounting plates 200 and baffles 320 are installed on the vegetation concrete layer 340. Drainage ditches 330 are installed on both sides of the mounting plates 200. The planting mat 370 in the mounting groove 310 can plant vegetation. When water flows on the roadbed slope, the vegetation in the mounting groove 310 stabilizes the soil and reduces soil erosion. The baffles 320 can intercept the washed-down soil to a certain extent. The water flow is discharged into the drainage ditch 330 through the water guide channel 360. The drainage ditch 330 can guide and discharge the water flow, which can stabilize and reinforce the roadbed slope and improve the protective stability of the protective structure.

[0036] like Figure 4 and Figure 5 As shown, a foot guard 380 is fixedly connected to the bottom of the mounting plate 200. Several evenly arranged first drainage grooves 381 are provided on the inner wall of the foot guard 380. The top of the foot guard 380 is aligned with the drainage ditch 330. A second drainage groove 382 is provided on the top of the shoulder guard 100.

[0037] In this embodiment, the foot guard 380 is aligned with the drainage ditch 330, which can transport the water flow in the drainage ditch 330 to the first drainage channel 381 on the foot guard 380. The first drainage channel 381 can discharge excess water flow. The shoulder guard 100 can intercept the water flow at the top of the roadbed slope and intercept and discharge the water flow through the second drainage channel 382, ​​thereby reducing the scouring of the roadbed slope by the water flow and improving the protective effect of the protective structure on the roadbed slope.

[0038] Working principle: First, a 3D mesh 350 is laid on the surface of the roadbed slope. Then, vegetation concrete is sprayed onto the 3D mesh 350 to form a vegetation concrete layer 340. Shoulder guards 100 are installed at the top of the roadbed slope. Multiple mounting plates 200 are evenly arranged on the vegetation concrete layer 340. Baffles 320 are installed with their bottoms aligned with the mounting plates 200. Multiple drainage ditches 330 are installed on both sides of the mounting plates 200. Foot guards 380 are installed at the bottom of the roadbed slope and aligned with the drainage ditches 330. The components include shoulder guards 100, mounting plates 200, baffles 320, drainage ditches 330, and foot guards 380. All are connected together by concrete. The planting mat 370 is placed in the installation groove 310, and then vegetation seeds are planted on the planting mat 370. It works in conjunction with the vegetation concrete layer 340 to maintain the vegetation. When the roadbed slope is eroded by water flow, the baffle 320 can intercept the eroded soil and guide the water flow to the drainage ditch 330 through the water guide channel 360. The water flow along the drainage ditch 330 to the foot guard 380. The foot guard 380 can guide and discharge the water flow through the first drainage channel 381. The shoulder guard 100 discharges the water flow on the roadbed slope through the second drainage channel 382.
