Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of highway slope protection, concretely relates to a highway slope reinforcing structure. BACKGROUND

[0002] With the rapid development of highway construction, the stability of the slope, as an important part of the highway, is directly related to the safe operation of the road and the balance of the surrounding ecological environment. The highway slope often faces complex geological conditions and natural environment, such as weathering, erosion, rainwater erosion and other natural factors, as well as the influence of human activities such as blasting construction, which may lead to the loosening and instability of the slope rock-soil mass. Once the slope occurs landslide, collapse and other disasters, it will not only have a serious impact on the traffic of the highway, but also may threaten the safety of life and property of the surrounding residents.

[0003] In order to cope with these challenges, the highway slope reinforcing technology has emerged. This technology mainly includes two methods, one is to use a series of engineering measures such as grouting reinforcement, anchor rod reinforcement, soil nailing reinforcement, anti-slide pile, etc. to reinforce the slope as a whole or locally to improve the anti-slide and anti-collapse ability of the slope. Although this mode can realize the slope reinforcement, the grouting and other methods will affect the ecological environment of the slope, and the later maintenance is more complicated; the other method is ecological slope reinforcement technology, which realizes slope reinforcement through the gripping force of the vegetation roots and promotes the recovery of slope vegetation and the improvement of ecological environment.

[0004] The prior art such as patent application No. 202020391028.3 proposes an ecological slope, which comprises a slope body, a plurality of planting holes are formed on the slope surface of the slope body, a net and a substrate layer are sequentially laid on the slope surface from bottom to top, the net is anchored to the slope body, the thickness of the net is 2-4cm, the thickness of the substrate layer is 5-8cm; plants are planted in the planting holes. Although the above ecological slope can realize the prevention of water and soil loss and other problems, it still has the following deficiencies:

[0005] 1. The slope needs to be planted artificially when laying or planting plants, which is more dangerous on the slope with high slope.

[0006] 2. The device is anchored on the slope surface by the net, and the anchor nails need to be pulled out again for secondary positioning and anchoring when reinforcing later, which has high later maintenance cost. UTILITY MODEL CONTENT

[0013] Preferably, it also includes an anchoring nail, the length of which is greater than the length of the anchoring rod; the anchoring nail passes through the first through hole, pushes open the drill bit, and then passes through the second through hole to insert into the slope.

[0031] Example 1:

[0032] Please see Figures 1-6In order to solve the problem of ecological slope 2 reinforcement on steep slope surface 23, this embodiment proposes a highway slope reinforcement structure, including several ecological blankets 1, which are laid on the slope 2 in sequence; a pressing component 3 is provided between adjacent ecological blankets 1, which presses the ecological blankets 1 onto the surface of the slope 2; adjacent pressing components 3 are connected by connecting components 4; several steps 32 for easy walking are opened on the pressing component 3 along the slope 2 direction.

[0033] In this embodiment, the pressing component 3 includes a pressing plate 33, the bottom surface of which presses against the slope 2, and a step 32 is provided on the top surface of the pressing plate 33; the two ends of the pressing plate 33 are respectively connected to a fixing plate 31, which is provided at the top 21 and bottom 22 of the slope 2, and the two ends of the ecological blanket 1 are pressed against the bottom of the pressing components 3 on both sides.

[0034] When in use, the above-mentioned holding component 3 only needs to be rolled up first, and then a person stands on the top of the slope 21 to roll the ecological blanket 1 down to cover the slope surface 23. Then, the holding component 3 is pressed on the ecological blanket 1, and the holding component 3 is fixed at the top of the slope 21 and the bottom of the slope 22 to fix the ecological blanket 1. After that, the slope surface 23 can be constructed by standing on the steps 32 of the holding component 3.

[0035] Example 2:

[0036] Please see Figure 3 In this embodiment, the connecting component 4 includes a connecting block 41, with inclined blocks 42 connected to both ends of the connecting block 41. An inclined groove 34 is opened at the end of the corresponding fixing plate 31. The two inclined blocks 42 are respectively inserted into the inclined grooves 34 on the two adjacent fixing plates 31. The anchor nail 7 passes through the connecting block 41, the fixing plate 31 and the ecological blanket 1 in sequence and is then inserted into the slope 2.

[0037] In this embodiment, the connecting component 4 fixes the top 21 and bottom 22 of the slope of the ecological blanket 1 and the pressing component 3 through the anchor nail 7. At the same time, when the anchor nail 7 is pressed down to fix it, the fixing plates 31 of the adjacent pressing components 3 can be pulled tight in opposite directions by the inclined block 42, so that all the pressing components 3 form a unified whole and prevent the partial detachment due to loosening of one part.

[0038] Example 3:

[0039] Continue reading Figures 1-6For the construction of slope 23, reinforcement plates 6 can be used. Several reinforcement plates 6 are connected between adjacent pressure components 3. The reinforcement plates 6 are connected to the pressure plate 33 through anchoring components 5. The bottom of the reinforcement plates 6 between adjacent pressure plates 33 is thickened so that the bottom can press on the ecological carpet 1 of the slope 23 to fix the ecological carpet 1. Only a few people need to carry the reinforcement plates 6 up the steps 32 at the same time, and fix the reinforcement plates 6 to the pressure plate 33 from top to bottom to complete the lateral fixation and pressure of the ecological carpet 1.

[0040] To facilitate secondary reinforcement, in this embodiment, the anchoring assembly 5 includes an anchor rod 51. The anchor rod 51 is hollow inside. A first through hole 52 is opened at the top of the anchor rod 51, and a second through hole 53 with a radius that gradually decreases from the outside to the inside is opened at the bottom. A drill bit 54 is detachably connected to the wall of the second through hole 53. The anchor rod 51 passes through the reinforcing plate 6 and the pressure plate 33 in sequence and is then fixed on the slope 23.

[0041] During the first anchoring, the top of the anchor rod 51 is provided with a top cover 57. The inner ring of the top cover 57 has an internal thread, and the corresponding outer wall of the top of the anchor rod 51 has an external thread. The top cover 57 can be threadedly connected to the top of the anchor rod 51.

[0042] During the second reinforcement, there is no need to re-drill holes in the pressure plate 33 and the reinforcement plate 6. Simply open the top cover 57, pass the anchor nail 7 with a length greater than that of the anchor rod 51 through the first through hole 52, push the drill bit 54 open and pass it out through the second through hole 53 to insert it into the slope 23 to achieve secondary fixation.

[0043] In addition, several transverse through holes 55 are opened on the side wall of the anchor rod 51, and a reinforcing rod 56 is slidably connected in the transverse through holes 55. One end of the reinforcing rod 56 can extend out of the anchor rod 51 and is connected to the anchor head; the other end is located in the anchor rod 51 and has a beveled surface, so that the anchor head can extend out of the anchor rod 51 as the anchor nail 7 is pressed down.

[0044] The aforementioned anchoring component 5 facilitates subsequent maintenance and secondary reinforcement, resulting in better reinforcement of slope 2.

[0045] Example 4:

[0046] Please see Figure 6 In this embodiment, the ecological blanket 1 includes a plant fiber layer 12, the top of the plant fiber layer 12 is connected to an upper shaping net 11, the bottom surface of the plant fiber layer 12 is connected to a seed layer 13, the bottom of the seed layer 13 is connected to a nutrient layer 14, and the bottom of the nutrient layer 14 is connected to a lower shaping net 15. The upper shaping net 11 and the lower shaping net 15 are connected to fix the plant fiber layer 12, the seed layer 13 and the nutrient layer 14 between the upper shaping net 11 and the lower shaping net 15.

[0047] The advantages of the above-mentioned ecological blanket 1 are:

[0048] (1) It protects the slope 23 from rainwater erosion by its own tensile force. It can withstand a flow velocity of 1.2-1.8 m / s in the long term and up to 3 m / s in the short term, thus preventing soil erosion caused by the flow of surface water.

[0049] (2) Strong wind erosion resistance: Its roughness is 600 times higher than that of quicksand, reducing sand transport by 99% and wind speed resistance up to 10m / s. It can create suitable growing conditions for vegetation in harsh climates and can effectively prevent dust from occurring during construction, thus replacing dust nets.

[0050] (3) It effectively inhibits the evaporation of soil moisture, ensures soil humidity and temperature, has good air permeability, and can avoid direct sunlight, which is beneficial to the early growth of plants.

[0051] (4) All materials of the ecological blanket 1 are non-toxic, non-polluting and degradable. The straw, coconut fiber and shaping net (PP net) have different degradation cycles, which can continuously provide nutrients to plants at different stages of growth and increase the organic matter content of the soil until the ecological blanket is completely degraded.

[0052] (5) Using ecological grass mats with added carbon particles on the slope 2 of the highway can absorb vehicle exhaust to a certain extent.

[0053] (6) Low cost. Both material and construction costs are far lower than traditional masonry protection and other green protection methods such as topsoil spraying and planting bags. The overall cost is less than 1 / 3 of other protection methods.

[0054] (7) The construction is simple and quick, which greatly promotes plant growth and is almost unaffected by soil quality and roadbed height;

[0055] (8) In addition to the slope 2 of the highway, the ecological blanket 1 also has great application prospects in landscaping, mine reclamation, desertification control and other projects.

[0056] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
