Description

Technical Field

[0002] In water conservancy projects, it is necessary to protect the river embankments or slopes on both sides to prevent soil erosion caused by rain erosion. In the prior art, slope protection nets are used for reinforcement and protection. The existing slope protection nets on the market usually use a whole piece of metal protection net to cover the river embankments or slopes on both sides, and are directly fixed with fixed gripping parts to achieve the purpose of preventing soil erosion. The existing slope protection nets have the following shortcomings when in use: 1. The slope protection net lacks a buffer unloading support structure. Under the impact of rain for a long time, the slope protection net is prone to damage by impact, thereby reducing the service life of the slope protection net; 2. The slope protection net is directly fixed with fixed gripping parts. When the slope protection net needs to be replaced or repaired, a large amount of manpower is required to remove the fixed gripping parts from the soil and release the fixation for replacement or repair. This operation method has high labor intensity and low work efficiency and cannot meet the use requirements. Based on the above situation, we propose a slope protection net for water conservancy project design. Utility Model Content

In addition, the slope protection net main body 100 can be disassembled, assembled and replaced by a simple rotation, and there is no need for personnel to take out the anchor rods from the soil for de-fixing and replacement, which saves a lot of labor and thus improves work efficiency.

[0028] Working principle: When in use, the slope protection net body 100 is fixed to the top of the circular support frame 1 by a fixed positioning mechanism. When fixing the entire device, first, the bottom of the circular support frame 1 and the bottom of the two fixing plates 12 are in active contact with the slope surface, and then the T-shaped fixing anchor rod 11 is inserted into the soil through the corresponding through hole by a hammer, and then the pressing plate 14 is aligned with the top of the corresponding T-shaped fixing anchor rod 11, and the pressing plate 14 is knocked down by knocking, and the pressing plate 14 drives the first fixing anchor rod 13 to be inserted downward into the soil. After the six T-shaped fixing anchor rods 11 and the six first fixing anchor rods 13 are inserted, the bite force of the six T-shaped fixing anchor rods 11 and the six first fixing anchor rods 13 with the soil can be used to fix the entire device, and the fixing stability is improved by superimposing and pressing the pressing plate 14 and the T-shaped fixing anchor rod 11.

[0029] After installation, when in use, the arched support frame 1 and the support plate 12 are in contact with the slope surface, and the bottom of the slope protection net main body 100 is supported by multiple first support rods 2 and multiple second support rods 3. When subjected to the impact force of rain and mud, the impact force is the impact force away from the slope surface, and the impact force will first impact the first support rod 2 and the second support rod 3. Under the impact force, the first support rod 2 and the second support rod 3 move in the direction away from the slope surface, and the first support rod 2 and the second support rod 3 drive the arched support frame 1 to move, and the arched support frame 1 drives the multiple guide rods 9 to slide in the guide holes of the corresponding guide blocks 8 respectively. While the arched support frame 1 moves, it compresses the multiple buffer springs 10. Under the elastic force of the multiple buffer springs 10, the impact force of rain, mud and soil can be effectively buffered and unloaded, and with the support of the first support rod 2 and the second support rod 3 at the bottom, the risk of the slope protection net main body 100 being damaged by hard impact can be effectively reduced, thereby improving the safety and service life of the slope protection net main body 100.

[0030] After long-term use, when the slope protection net main body 100 is damaged and needs to be repaired or replaced, the corresponding handle rod 6 can be rotated in the opposite direction, and the handle rod 6 drives the corresponding compression nut 5 to rotate on the positioning screw 4 and separate from it, and the compression nut 5 drives the corresponding anti-slip rubber ring 15 to separate from the slope protection net main body 100 and the corresponding positioning screw 4. When the multiple compression nuts 5 on the top of the slope protection net main body 100 are removed, the obstruction on the top of the slope protection net main body 100 can be removed, and the slope protection net main body 100 can be directly removed upward for replacement or repair. After replacement or repair, the slope protection net main body 100 is again set on the corresponding multiple positioning screws 4 and rotated forward by the handle rod 6 drives the corresponding compression nut 5 and anti-skid rubber ring 15 to be sleeved on the positioning screw 4. When the bottom of the anti-skid rubber ring 15 contacts the top of the slope protection net main body 100, the rotation of the handle rod 6 is stopped. When multiple compression nuts 5 and anti-skid rubber rings 15 are sleeved on the corresponding positioning screws 4, the slope protection net main body 100 can be fixed. This method of fixing the slope protection net main body 100 to the circular support frame 1 through a fixed positioning mechanism can disassemble and replace the slope protection net main body 100 by rotating the handle rod 6. There is no need for personnel to take out the anchor rod from the soil for unfastening and replacement. Compared with the traditional disassembly method, a lot of labor is saved, thereby improving work efficiency.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
