Modular prefabricated component for ecological slope protection of high-cold slopes

Abstract

This utility model discloses a modular prefabricated component for ecological slope protection in cold regions, including a slope body with an internal drainage mechanism to reduce water erosion. A protective net is laid on the upper surface of the slope, and a drainage ditch is installed at the lower end of the net. This allows rainwater to quickly flow into drainage pipes and then into drainage ditches during rainy weather, reducing water erosion. The protective net design prevents rocks from rolling down the slope surface and causing traffic accidents. Furthermore, the net does not damage or alter the original landform or vegetation growth conditions of the slope. Its open design preserves the necessary conditions for subsequent artificial slope greening, allowing green plants to grow freely in its open space. Anchor rods are inserted into the slope body to press the insulation layer against the outer surface of the slope, facilitating the installation of the protective net. The design of the anti-tensile head increases the tensile strength of the anchor rods, preventing them from being pulled out of the slope body.

Description

Technical Field

[0001] This utility model relates to the technical field of slope protection devices, specifically to modular prefabricated components for ecological slope protection in cold regions. Background Technology

[0002] Slope protection is a common construction element in highway engineering, and it is also involved in some mountainous towns. As my country's highway mileage gradually increases, the effectiveness of slope protection measures is crucial to the quality and safety of construction. In recent years, ecological environment protection has received increasing attention; however, traditional highway construction techniques and slope protection measures have damaged vegetation around highways, harmed the ecological environment, and hindered ecological restoration within the highway area.

[0003] For example, the prefabricated assembled high slope ecological slope protection UHPC component disclosed in the authorization announcement number CN215329950U includes a prefabricated concrete square plate, reserved planting holes, reserved soil nail holes, and prefabricated soil nails; the prefabricated concrete square plate includes connecting member rods and connecting grooves; the prefabricated concrete square plate is divided into A square plate and B square plate, the side of the A square plate is provided with outwardly protruding connecting member rods, and the side of the B square plate is provided with inwardly recessed connecting grooves.

[0004] This prefabricated UHPC ecological slope protection component for high slopes utilizes the splicing structure of concrete square slabs to achieve rapid and efficient installation of the slope protection; the excellent tensile, compressive and shear properties of UHPC high-strength concrete further enhance the strength of the slope protection structure, making it better suited for the protection of high slopes. It belongs to the fields of geotechnical engineering and slope protection technology.

[0005] As can be seen from the solutions disclosed in the existing patent documents, during rainy weather, rainwater easily forms water flow on the slope surface and flows down the slope to erode it. The existing precast concrete slabs cannot prevent water flow from flowing down the slope surface and eroding it. In addition, the precast soil nails are designed with a conical structure and have low tensile strength. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0006] The purpose of this invention is to provide modular prefabricated components for ecological slope protection in cold regions, in order to solve the problems existing in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a modular prefabricated component for ecological slope protection in cold regions, comprising a slope body, wherein a drainage mechanism is installed inside the slope body to reduce water erosion of the slope body, the drainage mechanism including a drainage pipe installed inside the slope body, an inlet pipe connected to the upper end of each drainage pipe, a drainage trough connected to the upper end of each inlet pipe, a protective net covering the upper surface of the slope body, and a drainage ditch provided at the lower end of each drainage pipe;

[0008] The upper surface of the protective net is covered with an insulation layer, and a pad is pressed onto the upper surface of the insulation layer. An anchor rod is connected to the lower surface of the pad, and an anti-tensile head is provided on the outside of the anchor rod. A precast concrete square slab is poured and connected to the upper surface of the insulation layer, and a planting trough is provided inside the precast concrete square slab.

[0009] Preferably, a water inlet pipe is laid inside the slope, and anchor rods are inserted inside the protective net.

[0010] Preferably, the interior of the slope is provided with a drainage trough, and the upper surface of the drainage trough is in close contact with the protective net.

[0011] Preferably, anchor rods are inserted inside the slope, anchor rods are inserted inside the insulation layer, anti-tensile heads are inserted inside the slope, and connecting pads are poured inside the precast concrete square slab.

[0012] Preferably, a precast concrete slab is cast at the lower end of one side of the slope, a drainage pipe is cast inside the lower end of the precast concrete slab, and a drainage ditch is cast at the lower end of the precast concrete slab.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This modular prefabricated ecological slope protection component for high-altitude and cold slopes uses a protective net to be laid on the upper surface of the slope and a drainage ditch installed at the lower end of the net. This allows rainwater on the upper surface of the slope to quickly flow into the drainage pipe and then into the drainage ditch during rainy weather, reducing the erosion of the slope by flowing water. The design of the protective net can prevent stones from rolling down the slope surface and causing traffic accidents. Moreover, the protective net does not damage or change the original landform and vegetation growth conditions of the slope. Its open feature preserves the necessary conditions for subsequent artificial slope greening, allowing green plants to grow freely in its open space.

[0015] By inserting anchor bolts into the slope, the insulation layer is pressed tightly against the outer side of the slope, facilitating the installation of the protective net. The design of the anti-tensile head can improve the tensile strength of the anchor bolts and prevent them from being pulled out of the slope. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 The modular prefabricated ecological slope protection component shown in the figure includes a slope body 1. The slope body 1 is equipped with a drainage mechanism to reduce the erosion of the slope body 1 by water flow. The drainage mechanism includes a drainage pipe 11 installed inside the slope body 1. The upper end of the drainage pipe 11 is connected to a water inlet pipe 12. The upper end of the water inlet pipe 12 is connected to a drainage trough 13. A protective net 14 is laid on the upper surface of the slope body 1. A drainage ditch 15 is set at the lower end of the drainage pipe 11.

[0022] An insulation layer 2 is laid on the upper surface of the protective net 14. A pad 21 is pressed on the upper surface of the insulation layer 2. An anchor 22 is connected to the lower surface of the pad 21. Tensile head 23 is set on the outside of the anchor 22. A precast concrete square slab 24 is poured and connected to the upper surface of the insulation layer 2. A planting trough 25 is set inside the precast concrete square slab 24.

[0023] Please see Figure 1-2 Water inlet pipe 12 is laid inside the slope 1, and anchor rod 22 is inserted inside the protective net 14;

[0024] With this setup, by laying a protective net 14 on the upper surface of the slope 1 and installing a drainage ditch 13 at the lower end of the protective net 14, rainwater on the upper surface of the slope 1 can quickly flow into the drainage pipe 11 and be directed to the drainage ditch 15 for drainage during rainy weather, thereby reducing the erosion of the slope 1 by the flowing water.

[0025] Please see Figure 1-2 Drainage troughs 13 are laid inside the slope 1, and the upper surface of the drainage troughs 13 is tightly attached to the protective netting 14.

[0026] With this setup, the design of the protective net 14 can prevent stones from rolling down the surface of the slope 1 and causing traffic accidents. Moreover, the protective net 14 does not damage or change the original landform and vegetation growth conditions of the slope. Its open feature preserves the necessary conditions for subsequent artificial slope greening, and green plants can grow freely in its open space.

[0027] Please see Figure 1 and Figure 3 Anchor rods 22 are inserted inside the slope 1, anchor rods 22 are inserted inside the insulation layer 2, anti-tensile head 23 is inserted inside the slope 1, and connecting pad 21 is poured inside the precast concrete square slab 24.

[0028] With this setup, by inserting the anchor rod 22 into the interior of the slope 1, the insulation layer 2 is pressed against the outer side of the protective net 14, which facilitates the fixed installation of the protective net 14. The design of the tensile head 23 can improve the tensile strength of the anchor rod 22 and prevent the anchor rod 22 from being pulled out of the slope 1.

[0029] Please see Figure 1 and Figure 3 A precast concrete slab 24 is poured at the lower end of one side of the slope 1. A connecting drainage pipe 11 is poured inside the lower end of the precast concrete slab 24. A connecting drainage ditch 15 is poured at the lower end of the precast concrete slab 24.

[0030] With this setup, by casting and connecting precast concrete square slabs 24 on the upper surface of the insulation layer 2, green vegetation can be planted inside the planting trough 25, which slows down the flow speed of rainwater on the slope, allowing rainwater more time to infiltrate into the soil, reducing the erosion of the soil by surface runoff, thereby controlling soil loss. At the same time, the roots of the green vegetation intertwine within the slope 1, strengthening the stability of the slope 1 and reducing the possibility of soil being washed away by rainwater.

[0031] The working principle of this embodiment is as follows: The modular prefabricated component for ecological slope protection for high-altitude cold slopes lays a protective net 14 on the upper surface of the slope 1 and installs a drainage ditch 13 at the lower end of the protective net 14, so that rainwater on the upper surface of the slope 1 can quickly flow into the drainage pipe 11 and be directed into the drainage ditch 15 for drainage during rainy weather, thereby reducing the erosion of the slope 1 by the flowing water.

[0032] The design of the protective net 14 can prevent stones from rolling down the surface of the slope 1 and causing traffic accidents. The protective net 14 does not damage or change the original landform and vegetation growth conditions of the slope. Its open feature preserves the necessary conditions for subsequent artificial slope greening, and green plants can grow freely in its open space.

[0033] It is worth noting that the design of the drainage trough 13 can extend the interception of water flow, expand the drainage area, and effectively reduce the erosion of the slope 1 by the water flow.

[0034] By inserting anchor rods 22 into the interior of slope 1, the insulation layer 2 is pressed against the outer side of slope 1, which facilitates the installation of the protective netting 14. By pouring and connecting precast concrete square slabs 24 on the upper surface of the insulation layer 2, green vegetation can be planted inside the planting trough 25, which slows down the flow speed of rainwater on the slope, allowing rainwater to have more time to infiltrate into the soil, reducing the erosion of the soil by surface runoff, thereby controlling soil loss. At the same time, the roots of the green vegetation are intertwined in the slope 1, which strengthens the stability of the slope 1 and reduces the possibility of soil being washed away by rainwater.

[0035] It is worth noting that the design of the tensile head 23 can improve the tensile strength of the anchor rod 22 and prevent the anchor rod 22 from being pulled out of the slope 1.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
