Detailed Implementation

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

[0026] Example 1

[0027] like Figure 1 As shown, this embodiment discloses an octagonal protective net unit, which includes several octagonal wire rope loops 1. All the octagonal wire rope loops 1 have the same shape, which can be regular octagonal or non-regular octagonal. In this embodiment, the octagonal wire rope loops 1 are set to regular octagonal.

[0028] Furthermore, each octagonal wire rope loop 1 is of a different size and is arranged sequentially inside and outside; that is, the larger octagonal wire rope loop 1 surrounds the smaller octagonal wire rope loop 1, the center points of all octagonal wire rope loops 1 coincide, and the eight corners are aligned one-to-one. The corresponding vertices of all octagonal wire rope loops 1 are connected together by connecting wire ropes 2. In other words, the eight vertices of all octagonal wire rope loops 1 are connected together by eight connecting wire ropes 2, thus forming a spider web-like structure within the octagonal protective net unit. Figure 1 As shown.

[0029] In the specific setup, the octagonal wire rope ring 1 and the connecting wire rope 2 are connected by a protective net cross buckle 13, so that all the octagonal wire rope rings 1 are connected into a whole.

[0030] The octagonal protective net unit in this embodiment is composed of multiple octagonal steel wire rope loops 1 connected on the inner and outer perimeters, which can better disperse stress and has stronger tensile and puncture resistance.

[0031] Example 2

[0032] This embodiment discloses a protective net composed of the octagonal protective net units from Embodiment 1, such as... Figure 2 As shown, the protective net includes several octagonal protective net units 3 as in Embodiment 1. All the octagonal protective net units 3 are arranged in a matrix, and the two opposite vertices of two adjacent octagonal protective net units 3 are connected to each other.

[0033] In practical implementation, all octagonal protective netting units 3 are laid in a matrix on the slope requiring protection. The two opposite vertices of two adjacent octagonal protective netting units 3 are tied together with steel wire ropes. Alternatively, the two opposite vertices of two adjacent octagonal protective netting units 3 are fixed together with self-drilling anchor bolts 14. That is, while laying the octagonal protective netting units 3, self-drilling anchor bolts 14 are anchored into the slope at the two opposite vertices of two adjacent octagonal protective netting units 3. The anchor plates of the self-drilling anchor bolts 14 press the two opposite vertices of two adjacent octagonal protective netting units 3 firmly onto the slope, thereby connecting all the octagonal protective netting units 3 together to form a protective net. Figure 2 As shown.

[0034] In addition, such as Figure 2 As shown, the vertices located at the edge of the matrix are connected together by supporting steel wire ropes 4. The protective net is reinforced in the horizontal and vertical directions by supporting steel wire ropes 4, which makes the structure of the entire protective net more stable.

[0035] The protective net in this embodiment is spliced ​​together from several octagonal protective net units 3, which gives it better tensile strength and higher stability of the entire protective net.

[0036] Example 3

[0037] This embodiment discloses a slope protection system composed of the protective netting described in Embodiment 2. Specifically, the slope protection system includes the protective netting described in Embodiment 2, which is laid on the surface of the slope requiring protection.

[0038] During installation, the octagonal protective netting units 3 from Example 1 are laid one by one on the slope surface, with all octagonal protective netting units 3 arranged in a matrix. During installation, the positions of the two opposite vertices of two adjacent octagonal protective netting units 3 are anchored into the slope with self-drilling anchor rods 14. The rod body of the self-drilling anchor rod 14 is hollow, so it is not necessary to remove the drill rod during drilling. Instead, the anchor rod body directly replaces the drill rod. After drilling into the soil, it does not need to be removed. Grouting is performed on-site, and the mortar can automatically fill the hole through the hollow part in the rod body and the bottom grouting hole. The exposed part adopts an anchor plate structure. The anchor plate presses the two opposite vertices of two adjacent octagonal protective netting units 3 tightly onto the slope. This self-drilling anchor rod 14 is an existing mature technology, and its usage method will not be described in detail. After the octagonal protective net unit 3 is covered on the slope, the supporting steel wire rope 4 is passed through the holes of the octagonal protective net unit 3 located at the edge of the matrix, or the supporting steel wire rope 4 is used to connect and fix all the vertices of the matrix edge together. At this time, all the octagonal protective net units 3 are connected together to form a protective net that is fixedly laid on the slope.

[0039] As one implementation of this embodiment, the slope protection system also includes willow stakes planted on the slope, with the stakes planted in the gaps between four adjacent octagonal protective net units 3, such as... Figure 2 As shown.

[0040] As one implementation of this embodiment, the slope protection system may also include a hydroseeding layer 12, which is laid on top of the protective net. When willow stumps are planted on the slope, the hydroseeding layer 12 can avoid the planting location of the willow stumps.

[0041] The hydroseeding layer 12 is an existing greening method. It involves mixing grass seeds, water-retaining agents, adhesives, green fiber mulch, and fertilizers with water in a mixing container to form a gel-like slurry. This slurry is then sprayed onto the land to be sown using a pressure pump, thus forming the hydroseeding layer 12.

[0042] As one implementation of this embodiment, the slope protection system may further include anti-slide piles 9 installed on the slope. Specifically, during installation, the anti-slide piles 9 can pass through the central hole of the octagonal protective net unit 3 and be anchored to the slope. By installing the anti-slide piles 9, the slope protection system can be more firmly fixed to the slope.

[0043] As one implementation of this embodiment, the slope protection system also includes a drip irrigation system. Figure 3 As shown, the drip irrigation system includes a drainage ditch 8 set at the top of the slope and drip irrigation pipes laid on the hydroseeded grass layer 12; the inlet end of the drip irrigation pipes is connected to the drainage ditch 8.

[0044] In addition, the slope protection system also includes a water pump 5 and a water storage tank 6 connected to the water pump 5 via a pipe; the water storage tank 6 is connected to the intercepting ditch 8 via a pipe, and a filter screen 7 is installed on the outlet of the water storage tank 6.

[0045] Water is drawn into the water storage tank 6 by the water pump 5. The water in the water storage tank 6 also enters the intercepting ditch 8, and then is distributed from the intercepting ditch 8 to each drip irrigation pipe. Finally, the water leaks out from the drip irrigation pipe to irrigate the vegetation on the slope.

[0046] As one implementation of this embodiment, the slope protection system also includes a controller and a humidity monitoring device 11 installed on the slope. A solenoid valve is installed on the pipe between the water storage tank 6 and the intercepting ditch 8, and the solenoid valve is electrically connected to the humidity monitoring device 11. The humidity monitoring device 11 mainly consists of a humidity sensor, which collects humidity information from the hydroseeded vegetation layer 12 or the slope soil. If the humidity is insufficient, the controller controls the solenoid valve to open, replenishing the water into the intercepting ditch 8, thereby irrigating the vegetation, resulting in higher automation.

[0047] As one implementation of this embodiment, the slope protection system also includes a gabion 10; the gabion 10 is placed at the bottom of the slope and filled with stones. If a landslide occurs on the slope, the gabion 10 can prevent the landslide debris from falling onto the road surface.

[0048] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0049] Furthermore, the specific embodiments described above are exemplary. Those skilled in the art can devise various solutions inspired by the disclosure of this utility model, and these solutions all fall within the scope of this utility model and its protection. Those skilled in the art should understand that this utility model specification and its drawings are illustrative and not intended to limit the scope of the claims.
