Description

Technical Field

[0001] This utility model relates to the field of ecological restoration technology, specifically to an ecological greening slope protection structure based on wire mesh spraying. Background Technology

[0002] In various engineering construction projects, such as road construction and mining, a large number of slopes are often created. These slopes not only affect the natural landscape but also pose safety hazards such as soil erosion and slope collapse. Therefore, slope protection and ecological greening are particularly important. Ecological greening slope protection structures based on wire mesh and shotcrete are widely used in practical engineering as an effective slope management method.

[0003] Traditional ecological greening slope protection structures based on wire mesh and shotcrete typically involve drilling holes in the slope, inserting anchor bolts, fixing the steel mesh to the anchor bolts, and finally performing shotcrete to form a unified protective layer on the slope, upon which plants are then planted to achieve ecological greening.

[0004] However, existing protective structures have some obvious drawbacks. In actual use, when pedestrians or animals walk on the slope, they exert external forces on the steel mesh. Because the steel mesh is only fixed by anchor bolts, its stability on the slope is poor, and it is prone to sliding.

[0005] The slippage of steel mesh can severely damage slope vegetation. In the early stages of growth, the root systems of slope vegetation are relatively fragile. The slippage of the steel mesh directly damages the roots and stems of the plants, leading to poor growth or even death, thus affecting the ecological greening effect of the slope. Furthermore, the damage to vegetation can further exacerbate soil erosion and reduce slope stability.

[0006] Meanwhile, the slippage of the reinforcing mesh can also adversely affect the overall protective structure. It may loosen the connection between the mesh and anchor bolts, damage the bond between the shotcrete layer and the slope, and reduce the integrity and strength of the protective structure. Over time, this damage will intensify, leading to cracks and spalling in the protective structure, severely reducing its durability and reliability, and increasing the risk of slope collapses and other safety accidents. Therefore, an ecological greening slope protection structure based on shotcrete with reinforcing mesh is proposed to address these problems. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model proposes an ecological greening slope protection structure based on wire mesh shotcrete. This solves the technical problem mentioned in the background art: when pedestrians or animals walk on the slope, the wire mesh is prone to sliding, which damages the slope vegetation and the overall protection structure, thus reducing its durability and reliability.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an ecological greening slope protection structure based on wire mesh shotcrete, comprising:

[0009] A concrete layer is laid on the slope.

[0010] An anchor bolt is inserted into the slope surface, with one end exposed outside the slope surface;

[0011] A steel mesh layer is laid on the slope, and the anchor bolts are arranged at the nodes of the steel mesh layer;

[0012] A connecting component is disposed at the end of the anchor rod and connects to the node of the reinforcing mesh layer after the reinforcing mesh layer slides, thereby defining the position of the node of the reinforcing mesh layer; and

[0013] A curing layer is laid on the side of the steel mesh layer away from the slope.

[0014] In a preferred embodiment, multiple sets of through holes are formed on the slope surface.

[0015] In a preferred embodiment, a nut is screwed onto the end of the anchor rod exposed outside the slope, a steel washer is provided between the nut and the slope, and the connecting assembly is disposed on the nut.

[0016] In a preferred embodiment, the connection component includes:

[0017] A connecting sleeve is fixedly mounted on the nut and has a hollow structure. A retaining ring is provided on the connecting sleeve.

[0018] The mounting ring is slidably fitted onto the connecting sleeve along its axis; and

[0019] The hook is set on the mounting ring and can be locked onto the node of the steel mesh layer.

[0020] In a preferred embodiment, the inner side of the hook is a flat surface that abuts against the steel mesh layer, and the outer side of the hook is a sloping surface.

[0021] In a preferred embodiment, the curing layer comprises a three-dimensional galvanized mesh layer, a reinforced geogrid, and an ecological substrate layer arranged sequentially from bottom to top.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] During construction, the slope protection structure involves first manually cleaning the slope, then installing anchor bolts, followed by suspending a steel mesh layer, and then spraying a layer of concrete. Initially, the nodes of the steel mesh layer are located outside the connecting components. The steel mesh layer is then pulled so that its nodes enter the connecting components, which then constrain the node positions. Finally, a curing layer is laid. This protective structure effectively prevents the steel mesh layer from sliding on the slope, avoiding damage to slope vegetation and preventing damage to the overall protection structure, thus improving its durability and reliability.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0031] Example:

[0032] like Figures 1 to 3As shown, this utility model provides an ecological greening slope protection structure based on shotcrete with wire mesh, including a concrete layer 1 laid on the slope, anchor rods 6 passing through the slope, one end of the anchor rods 6 being exposed outside the slope, and a steel mesh layer 2 laid on the slope, with the anchor rods 6 arranged at the nodes of the steel mesh layer 2.

[0033] During construction, the slope surface is first cleaned and debris is removed manually, then anchor rods 6 are installed, and the steel mesh layer 2 is laid. Then, the concrete layer 1 is sprayed. At the same time, the anchor rods 6 provide initial support for the steel mesh layer 2 to prevent the steel mesh layer 2 from sliding significantly.

[0034] like Figure 1 , 3 As shown, in this embodiment, the end of the anchor rod 6 is provided with a connecting component. After the steel mesh layer 2 slides, it connects with the node of the steel mesh layer 2 to limit the position of the node of the steel mesh layer 2. The end of the anchor rod 6 exposed outside the slope is screwed with a nut 8. A steel washer 7 is provided between the nut 8 and the slope. The connecting component is provided on the nut 8. The connecting component includes a connecting sleeve 9 fixedly provided on the nut 8. The connecting sleeve 9 has a hollow structure and a retaining ring 10 is provided on the connecting sleeve 9. An installation ring 11 is slidably sleeved on the connecting sleeve 9 along its axis. A hook 12 is provided on the installation ring 11. The hook 12 can be locked onto the node of the steel mesh layer 2.

[0035] After the reinforcing mesh layer 2 is installed, in the initial state, the nodes of the reinforcing mesh layer 2 are located outside the hook 12, the inner side of the hook 12 is a straight surface that abuts against the reinforcing mesh layer 2, and the outer side of the hook 12 is a sloping surface. After a single reinforcing mesh layer 2 is installed, it can be pulled diagonally downwards. The sloping surface on the outer side of the hook 12 pushes the connecting sleeve 9 to slide along the axis of the connecting sleeve 9, allowing the nodes of the reinforcing mesh layer 2 to enter the inner side of the hook 12. The arrangement of the straight surface on the inner side of the hook 12 effectively prevents the reinforcing mesh layer 2 from detaching from the hook 12, thereby limiting the position of the reinforcing mesh layer 2 and preventing it from sliding on the slope.

[0036] like Figure 2 As shown, in this embodiment, a curing layer is laid on the side of the steel mesh layer 2 away from the slope. The curing layer includes a three-dimensional galvanized mesh layer 3, a reinforced geogrid 4, and an ecological substrate layer 5 arranged sequentially from bottom to top. Additionally, it is understood that in some preferred embodiments, a wire mesh layer can be laid outside the steel mesh layer 2 to further increase the strength of the curing layer. The ecological substrate layer 5 is an active matrix composed of plant fibers, water-retaining gel, microbial agents, etc., and has multiple sets of through holes 13 opened on the slope surface. The through holes 13 are filled and the surface is covered by a jet grouting process.

[0037] The specific usage and beneficial effects of this utility model are as follows:

[0038] During construction, the slope protection structure involves first manually cleaning the slope, then installing the anchor bolts 6, followed by suspending the steel mesh layer 2, and then spraying the concrete layer 1. Initially, the nodes of the steel mesh layer 2 are located outside the hook 12 in the connecting assembly. Then, the steel mesh layer 2 is pulled so that its nodes push the connecting sleeve 9 through the inclined surface outside the hook 12 until the nodes of the steel mesh layer 2 enter the hook 12. The hook 12 limits the position of the nodes of the steel mesh layer 2. Finally, the curing layer is laid out. This protection structure effectively prevents the steel mesh layer 2 from sliding on the slope, avoiding damage to the slope vegetation after sliding, and preventing damage to the overall protection structure after sliding, thus improving the durability and reliability of the protection structure.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
