Description

Technical Field

[0001] The present application belongs to the field of rock slope protection, and specifically relates to a rock slope protection structure. Background Art

[0002] Rock slopes are slopes composed of rock. Greening slope protection structures: Slope protection is an engineering measure used to protect slopes from erosion and collapse. Greening slope protection involves planting vegetation. The plant roots firmly anchor the soil, effectively preventing soil erosion and providing aesthetic benefits.

[0003] In the prior art, rock slopes are protected by lattice beam support or protective nets. Lattice beam support protects the slope surface by using mortared blocks, cast-in-place reinforced concrete or precast prestressed concrete, and fixes it with anchor rods or cables to achieve deep landslide protection of rock slopes. However, due to the large gap between lattice beams (usually there is a gap of 2-3m), this method cannot effectively protect shallow broken rock slopes. The protective net is fixed to the slope surface with short anchor rods of 3-4m in length, but because the anchor rod tension generally does not exceed 50kN, it cannot effectively protect deep rock slopes from instability. Lattice beams and protective nets have different protective functions for rock slopes, but due to the different fixing methods and laying requirements of the two, the prior art has not proposed a structure that can provide dual protection for deep and shallow rock slopes. Utility Model Content

[0004] The present application provides a rock slope protection structure, which solves the problem that rock slopes cannot be effectively protected at both shallow and deep levels at the same time.

[0005] The technical solutions adopted in this application are:

[0006] A rock slope protection structure, comprising:

[0007] a first protection unit, the first protection unit comprising a lattice beam arranged along the slope surface, the lattice beam being fixed to the rock slope by anchor rods;

[0008] a second protection unit, the second protection unit comprising a protection net connected to the lattice girder;

[0009] The third protection unit includes a growth bag connected to the protection net, wherein plants are placed in the growth bag, and the growth bag is provided with growth holes for the roots of the plants to pass through.

[0010] The lattice beams include transverse lattice beams and vertical lattice beams connected to the transverse lattice beams. Steel meshes are provided inside the transverse lattice beams and the vertical lattice beams, and the protective meshes are fixed to the steel meshes.

[0011] There are multiple transverse lattice beams and multiple vertical lattice beams, and fasteners are provided at the connection between the transverse lattice beams and the vertical lattice beams, and the other ends of the fasteners extend into the rock slope.

[0012] The distance between adjacent transverse lattice beams is 2-3 m, and / or the distance between adjacent vertical lattice beams is 2-3 m.

[0013] The adjacent transverse lattice beams and the vertical lattice beams connected to the transverse lattice beams enclose a plurality of protection cavities, and the protection net is provided in each of the protection cavities.

[0014] The growth bag is arranged in an inverted cone shape with an open upper end and a sealed bottom end, and a plurality of growth holes are provided on a side of the growth bag that is in contact with the protective net.

[0015] The growth holes are evenly distributed on the side where the growth bag and the protection net are in contact, or the growth holes are concentrated on the bottom of the growth bag.

[0016] Connectors are provided between the protective net and the lattice beam, and / or between the growing bag and the protective net.

[0017] The connecting member includes an annular lock.

[0018] The bottom surface of the protective net is in contact with the slope surface of the rock slope.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0020] (1) A first protection unit is set up, and the lattice beams of the first protection unit are used to achieve deep structural protection for the rock slope to prevent deep sliding and instability of the rock slope; the protection net of the second protection unit is used to achieve shallow structural protection for the rock slope to prevent shallow rock blocks from becoming unstable and falling, which endangers the safety of the slope foot; vegetation is planted on the rock slope through growth bags. Compared with the conventional slot planting of vegetation, its setting method is simpler and less costly to construct, and the growth bags are easy to deform according to the placement space, so they can cooperate well with the grid of the protection net to achieve good coordination and limitation. The plants in the growth bags can extend their roots through the growth holes to take root in the surface cracks of the rock slope, further preventing the rock slope from shallow collapse. The combination of the first protection unit, the second protection unit and the third protection unit can achieve deep and shallow dual protection for the rock slope. The lattice beams, the protection net and the plants work together to prevent the rock slope from deep sliding and instability and shallow collapse.

[0021] (2) The lattice beams are provided with transverse lattice beams and vertical lattice beams to achieve deep protection and fixation of the rock slope in different directions. The protective net is fixed to the steel mesh inside the transverse lattice beams and the vertical lattice beams through annular locks, so that the protective net can be attached to the slope surface of the rock slope through the protective cavity, thereby achieving shallow protection of the rock slope.

[0022] (3) The growth bag is set in an inverted cone shape, which is conducive to concentrating nutrients to plants to promote plant growth, and is convenient for nutrient filling and plant planting or sowing from the open end. The back of the growth bag is in close contact with the protective net, and the protective net is in close contact with the slope of the rock slope, which makes it easy for plant roots to pass through the growth holes on the back of the growth bag and take root in the surface cracks of the rock slope, thereby enhancing the shallow protection effect of the rock slope.

[0036] This application provides a rock slope protection structure, such as Figures 1 to 5 As shown, it includes: a first protection unit, the first protection unit includes a lattice beam 3 arranged along the slope surface, and the lattice beam 3 is fixed to the rock slope 1 through an anchor rod 2; a second protection unit, the second protection unit includes a protection net 4 connected to the lattice beam 3; a third protection unit, the third protection unit includes a growth bag 5 connected to the protection net 4, a plant 6 is placed in the growth bag 5, and the growth bag 5 is provided with a growth hole 51 for the roots of the plant 6 to pass through.

[0037] In this solution, a first protection unit is set up, and the lattice beam 3 of the first protection unit is used to realize deep structural protection of the rock slope 1 to prevent the rock slope 1 from deep sliding and instability; the protection net 4 of the second protection unit is used to realize shallow structural protection of the rock slope 1 to prevent the rock slope 1 from becoming unstable and falling, which endangers the safety of the slope foot; the vegetation planting of the rock slope 1 is realized by the growth bag 5. Compared with the conventional groove planting of vegetation, its setting method is simpler and less costly to construct, and the growth bag 5 is easy to deform according to the placement space, so This can cooperate well with the grid of the protective net 4 to achieve good cooperation and limitation. The plants 6 in the growth bag 5 can extend their roots through the growth holes 51 and take root in the surface cracks of the rock slope 1, further preventing the rock slope 1 from shallow collapse. The first protection unit, the second protection unit and the third protection unit are combined to achieve deep and shallow dual protection of the rock slope 1. The lattice beam 3, the protective net 4 and the plants 6 work together to prevent the rock slope 1 from deep sliding instability and shallow collapse.

[0038] In one embodiment, Figure 1 、 Figure 3 As shown, the lattice beam 3 includes a transverse lattice beam 31 and a vertical lattice beam 32 connected to the transverse lattice beam 31 . A steel mesh 33 is provided inside the transverse lattice beam 31 and the vertical lattice beam 32 , and the protective net 4 is fixed to the steel mesh 33 .

[0039] The supporting strength of the transverse lattice beams 31 and the vertical lattice beams 32 is strengthened by the steel mesh 33, and the protective net 4 is fixed on the steel mesh 33 inside the transverse lattice beams 31 and the vertical lattice beams 32, so that the protective net 4 can be attached to the slope surface of the rock slope 1 through the protective cavity and the protective net 4 wraps the entire slope surface of the rock slope 1, preventing the film from causing instability and falling of shallow rocks and endangering the safety of the slope foot.

[0040] Furthermore, a plurality of transverse lattice beams 31 and vertical lattice beams 32 are provided, and fasteners are provided at the connection between the transverse lattice beams 31 and the vertical lattice beams 32 , and the other ends of the fasteners extend into the rock slope 1 .

[0041] The plurality of transverse lattice beams 31 and the vertical lattice beams 32 are deeply connected to the rock slope 1 in the protection range at multiple locations, thereby ensuring that the rock slope 1 is reinforced as a whole.

[0042] Preferably, the distance between adjacent transverse lattice girders 31 is 2-3 m, and / or the distance between adjacent vertical lattice girders 32 is 2-3 m.

[0043] Preferably, the distances between two adjacent transverse lattice beams 31 and two adjacent vertical lattice beams 32 are the same, thereby strengthening the overall structural stability of the lattice beams 3 and increasing the overall reinforcement strength of the lattice beams 3 on the rock slope 1. Selecting a distance of 2-3m not only achieves a deep, overall fixation effect of the lattice beams 3 on the rock slope 1, but also provides sufficient space for installing the protective nets 4 and plants 6 between the lattice beams 3. If the distance is too large, effective fixation and protection of the rock slope 1 cannot be achieved. If the distance is too small, on the one hand, it will cause layout difficulties and increase the difficulty. On the other hand, it will not be convenient to install shallow protective elements on the rock slope 1, such as the protective nets 4 and plants 6.

[0044] Furthermore, adjacent transverse lattice beams 31 and vertical lattice beams 32 connected to the transverse lattice beams 31 enclose a plurality of protective cavities, and a protective net 4 is provided in each protective cavity. On the basis of setting the lattice beams 3, a protective cavity is further provided, vegetation is planted in the protective cavity or other protective devices are combined to further protect the rock slope 1. The form of the protective net 4 is selected to be combined with the lattice beams 3 to further protect the rock slope 1. The protective net 4 can protect the shallow gravel of the rock slope 1 and prevent the gravel from falling. The lattice beams 3 are fixed by anchor rods 2 to prevent deep cracking of the rock slope 1, thereby achieving shallow and deep double-layer protection of the rock slope. This method is simple to install and low in cost, and the lattice beams 3 and the protective net 4 can make use of existing technical structures.

[0045] Preferably, the bottom surface of the protective net 4 is in contact with the surface of the rock slope 1. The protective net 4 is a flexible net. When fixed, the flexible net can adapt to the surface of the rock slope 1 and the shape of the protective cavity of the lattice beam 3, so that it is closely attached to the surface of the rock slope 1 and covers the surface of the rock slope 1, forming a protective covering for the surface of the rock slope 1 and preventing collapse of the shallow layer of the rock slope 1.

[0046] In one embodiment, Figure 4 、 Figure 5 As shown, the growth bag 5 is arranged in an inverted cone shape with an open upper end and a sealed bottom end, and a plurality of growth holes 51 are provided on the side of the growth bag 5 that is in contact with the protective net 4 .

[0047] The inverted cone shape of the growth bag 5 facilitates the concentrated supply of nutrients to the plants 6, promoting their growth. It also facilitates nutrient filling and planting or sowing of the plants 6 from the open end. The back of the growth bag 5 is in close contact with the protective net 4, which in turn is in close contact with the surface of the rock slope 1. This facilitates the roots of the plants 6 to penetrate through the growth holes 51 on the back of the growth bag 5 and take root in the surface cracks of the rock slope 1, thereby enhancing the shallow protection of the rock slope 1. Furthermore, because the protective net 4 is formed in a crisscross pattern, i.e., it comprises multiple grids, the inverted cone shape of the growth bag 5 can adapt to the grid shape. The growth bag 5 can be fixed at the diagonal of the grid, making installation simple and cost-effective.

[0048] Preferably, the growth holes 51 are evenly distributed on the side where the growth bag 5 is in contact with the protective net 4 , or the growth holes 51 are concentrated on the bottom of the growth bag 5 .

[0049] The roots of the plant 6 continue to grow through the growth holes 51. Figure 5 As shown, the growth hole 51 is set on one side of the protective net 4 so that the roots of the plant 6 extend toward the rock slope 1 after passing through the growth hole 51 .

[0050] In one embodiment, Figure 3 、 Figure 4 As shown, a connecting piece is provided between the protective net 4 and the lattice beam 3 , and / or between the growing bag 5 and the protective net 4 . The connecting piece includes a ring lock 7 .

[0051] Specifically, the beam structure comprises transverse lattice beams 31 and vertical lattice beams 32. A protective net 4 is secured to the steel mesh 33 within the transverse and vertical lattice beams 31 and 32 via annular locks 7. This allows the protective net 4 to adhere to the surface of the rock slope 1 through the protective cavity, providing shallow protection for the rock slope 1. Furthermore, the protective net 4 is tightly attached to the rock slope 1, and the annular locks 7 secure the growth bag 5 to the protective net 4. This facilitates the growth bag 5's movement along the protective net 4 toward the rock slope 1, allowing the roots of the plant 6 to more quickly penetrate the shallow cracks of the rock slope 1.

[0052] In addition, the connecting pieces may also be connected in the form of bolts, rivets or adhesives to achieve the fixation of the protective net 4 and the growth bag 5.

[0053] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0054] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0055] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
