Description

Technical Field

[0001] This utility model relates to the field of erosion gully control technology, and in particular to a flexible protective grid device for erosion gully control. Background Technology

[0002] The flexible geogrid device for gully erosion control refers to the geocell and gabion mesh device with flexible protection function used in gully erosion control. The geocells are laid on the slope and bottom of the gully. Through the lateral restraint of the filling material by the geocells, the stability of the slope is improved, the slope soil sliding and collapse are prevented, and the resistance to water erosion is enhanced.

[0003] A search revealed Chinese patent publication number CN106609510A, which discloses a flexible slope protection device belonging to the field of ecological restoration engineering. Primarily used for river and lake slope protection and ecological restoration, the device comprises an integral honeycomb grid matrix, umbrella-shaped anchors, a filter pad layer, and a vegetation layer. It provides three-dimensional slope protection, flexible slope protection, and high-density soil and water conservation, offering low cost and convenient installation and maintenance, thus having significant application potential in ecological restoration. However, the deployed grid requires a high density of anchor bolts, necessitates high terrain flatness, and presents significant construction challenges and low efficiency on steep slopes and complex terrains. Developing foldable grid modules reduces on-site installation time through prefabrication and enhances construction safety through joint anchoring with anchors and grids. However, this approach still requires substantial manpower and resources, involves a large workload, and is prone to re-forming erosion gullies due to water erosion, making effective utilization of these gullies impossible. Furthermore, the large workload and high cost contribute to its complexity. Utility Model Content

Bolts two and three are then screwed into the outer walls of clamping blocks two from both sides, thus entering the inner wall of the outer frame to form a stable connection.

[0016] As a further description of the above technical solution:

[0017] The top wall of the clamping block 2 is threaded with bolt 2, and the upper and lower ends of the outer wall of the outer frame are equidistantly equipped with mounting components.

[0018] The above technical solution involves placing the clip in the groove on the outer wall of the outer frame, and then rotating the two fixing posts equidistantly into the threaded holes at the top of the clip, thereby allowing the fixing posts to enter the inner wall of the outer frame.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a flexible protective grid device for gully erosion control, comprising a gully bottom 1, slopes 2 fixedly connected to the left and right sides of the top wall of the gully bottom 1, a protective mechanism 3 installed on the inner side of the slopes 2 for controlling the gully erosion, and a fixing mechanism 4 installed on the outer side of the protective mechanism 3 for fixing the protective mechanism 3; the protective mechanism 3 includes a gully slope 301 fixedly connected to the inner wall of the slope 2, an outer frame 302 fixedly connected to the outer wall of the gully slope 301, multiple railings 305 equidistantly installed on the inner wall of the outer frame 302, a planting component 303 installed on the inner side of the outer frame 302, the planting component 303 including a protective grid 3031 equidistantly installed on the inner side of the outer frame 302, planting soil 3032 installed on the inner bottom wall of the protective grid 3031, a protective net 3033 fixedly connected to the right side of the outer wall of the protective grid 3031, and vegetation 3 fixedly connected to the right side of the outer wall of the planting soil 3032. 04. Vegetation 304 is installed inside the protective net 3033. The protective grid 3031 is composed of numerous small mesh openings, and its interior is filled with planting soil 3032. The protective net 3033 is used to prevent the loss of planting soil 3032. The planting soil 3032 must be water-resistant, not easily scattered, and suitable for plant growth. During use, the protective grid 3031 should be spliced ​​to the inside of the outer frame 302 according to the length of the ditch slope 301, placed at an angle, and fixed to the ditch slope. Above 301, vegetation 304 is planted inside the protective grid 3031. The selected vegetation 304 should have good water resistance and be able to survive when soaked in water for a long time. After the vegetation 304 grows, its root system will penetrate the protective grid 3031 and go deep into the soil of the ditch slope 301, thereby reinforcing the ditch slope 301, preventing erosion, and purifying water quality. During flood impact, vegetation 304 also has an energy reduction effect, which can effectively reduce the impact of water flow on the soil.

[0040] Specifically, the protective grid 3031 is composed of multiple small mesh grids, filled with planting soil 3032. The protective net 3033 prevents the planting soil 3032 from spilling out. The planting soil 3032 needs to be resistant to soaking, not easily dispersed, and suitable for plant growth. When in use, the protective grid 3031 is spliced ​​to the inside of the outer frame 302 according to the length of the ditch slope 301, placed obliquely and fixed on the ditch slope 301. Planting vegetation 304 is planted in the protective grid 3031. The vegetation 304 used needs to be water resistant and able to survive long-term immersion in water. After the vegetation 304 grows, the roots of the vegetation 304 penetrate the protective grid 3031 and take root in the soil of the ditch slope 301, thereby stabilizing the ditch slope 301, preventing erosion, and purifying water quality. During flood impact, the vegetation 304 also has an energy reduction function, effectively slowing down the impact of water flow on the soil.

[0041] Reference Figure 3 , Figure 4 and Figure 5 The fixing mechanism 4 includes a second clamping block 403, which is installed at the four corners on the left side of the outer wall of the outer frame 302. A first clamping block 401 is installed on the right side of the outer wall of the second clamping block 403. A first bolt 402 is threaded to the inner bottom wall of the second clamping block 403. A third bolt 405 is threaded to the front side of the outer wall of the second clamping block 403. A second bolt 404 is threaded to the top wall of the second clamping block 403. Mounting components 406 are installed at equal intervals at the upper and lower ends of the outer wall of the outer frame 302. The mounting components 406 include fixing posts 4061, which are installed inside the grooves on the outer wall of the outer frame 302. A clamping piece 406 is rotatably connected to the inner side of the fixing post 4061. 2. The clamping piece 4062 is threaded onto the inner wall of the railing 305. The railing 305 is placed at equal intervals at the bottom of the outer frame 302. Then, the clamping piece 4062 is embedded into the groove on the outer wall of the outer frame 302. Next, two fixing posts 4061 are screwed into the threaded holes at the top of the clamping piece 4062 at equal intervals, so that the fixing posts 4061 penetrate and enter the inner wall of the outer frame 302, thereby firmly connecting the outer frame 302 and the railing 305 together. The clamping block 1 401 and clamping block 2 403 are placed at the four corners of the outer frame 302 respectively. Then, bolt 1 402 is screwed in from the bottom of clamping block 1 401 to fix clamping block 1 401 and clamping block 2 403. Finally, screw bolts 404 and 405 into the outer walls of the clamping block 403 from both sides until they enter the inner wall of the outer frame 302 to form a stable connection. This structure can effectively prevent the connection of the outer frame 302 from loosening and avoid affecting the stability of the overall structure due to falling off.

[0042] Specifically, the railing 305 is placed at equal intervals at the bottom of the outer frame 302. Then, the clamping piece 4062 is placed in the groove on the outer wall of the outer frame 302. Then, the two fixing posts 4061 are rotated at equal intervals into the threaded holes at the top of the clamping piece 4062, so that the fixing posts 4061 enter the inner wall of the outer frame 302, fixing the outer frame 302 and the railing 305 together. The clamping block 1 401 and clamping block 2 403 are placed at the four corners of the outer frame 302. Then, the bolt 1 402 is screwed in from the bottom of the clamping block 1 401, fixing the clamping block 1 401 and clamping block 2 403 together. Then, the bolt 2 404 and bolt 3 405 are screwed in from the outer walls on both sides of the clamping block 2 403, so that they enter the inner wall of the outer frame 302, forming a stable connection and preventing the connection of the outer frame 302 from loosening and falling off, which would affect the overall structural stability.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The top wall of the slope 2 is fixedly connected to a water-absorbing sheet 5, the top wall of the water-absorbing sheet 5 is fixedly connected to water-absorbing blocks 8 at equal intervals, the top wall of the water-absorbing sheet 5 is fixedly connected to a water-absorbing layer 6, and the top wall of the water-absorbing layer 6 is fixedly connected to the ground 7.

[0044] Specifically, the water-absorbing block 8 guides water to the water-absorbing sheet 5. The water-absorbing sheet 5 is mainly used to absorb and store water and regulate soil moisture. In the treatment of erosion gullies, it can slow down rainwater runoff, increase water infiltration, and reduce soil erosion. At the same time, maintaining suitable soil moisture helps the growth and recovery of vegetation 304, provides a continuous water supply for vegetation 304, improves the survival rate and growth quality of vegetation 304, and thus enhances the slope protection effect of the flexible retaining grid device.

[0045] Working principle: The protective grid 3031 is a grid structure composed of numerous tiny mesh openings, carefully filled with planting soil 3032 with special properties. This planting soil 3032 not only needs to be resistant to soaking but also ensures that it does not easily disperse under prolonged water immersion, while also meeting the needs of plant growth. In practical applications, the protective grid 3031 is spliced ​​according to the length of the ditch slope 301, placed inside the outer frame 302, and then placed diagonally and firmly fixed to the ditch slope 301. These protective grids 3031 are planted with highly water-resistant vegetation 304. This vegetation 304 can survive in water for a long time. As the vegetation 304 grows, its roots will penetrate the protective grid 3031 and take root in the soil of the ditch slope 301, thereby stabilizing the ditch slope 301 and effectively preventing the erosion of the ditch slope 301. In addition, the vegetation 304 also has the function of purifying water quality. Under the impact of floods, the vegetation 304 can also play an energy reduction role, significantly reducing the impact of water flow on the soil.

[0046] To further enhance structural stability, railings 305 are placed at equal intervals at the bottom of the outer frame 302. Next, clamping pieces 4062 are placed in grooves on the outer wall of the outer frame 302. Then, two fixing posts 4061 are rotated at equal intervals into the threaded holes at the top of the clamping pieces 4062, allowing the fixing posts 4061 to penetrate deep into the inner wall of the outer frame 302, thus firmly fixing the outer frame 302 and railings 305 together. Subsequently, clamping blocks 1 401 and 2 403 are placed at the four corners of the outer frame 302, and bolts 1 402 are screwed in from the bottom of clamping block 1 401, securing clamping blocks 1 401 and clamping blocks 305 together. The two 403 are tightly fixed together. Finally, bolts 404 and 405 are screwed into the outer walls of the two sides of the clamping block 403, so that they enter the inner wall of the outer frame 302, forming a stable connection. This design can effectively prevent the connection of the outer frame 302 from loosening and avoid the phenomenon of falling off due to loose connection, thereby ensuring that the stability of the overall structure is not affected. In addition, this structural design can withstand greater external impact, ensuring that the entire protection system can still maintain its integrity and functionality under severe weather conditions, such as strong winds or heavy rain, providing long-term and stable protection for the ditch slope 301.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
