Description
Technical Field
[0001] The utility model relates to the technical field of geological slope reinforcement, in particular to a load-relief fissure geological slope reinforcement structure. Background Art
[0002] In the field of geological engineering, the stability of geological slopes is an important factor related to engineering safety, especially those slopes with unloading cracks. Due to the unloading effect, cracks will appear in the rock mass, which not only affects the overall stability of the slope, but may also lead to geological disasters. Therefore, the reinforcement of geological slopes with unloading cracks is an urgent problem to be solved in engineering practice. Traditional slope reinforcement methods mostly use structures such as anchor rods and anchor cables for reinforcement. However, these methods are not ideal in dealing with unloading cracks. On the one hand, the distribution of unloading cracks is often irregular, and it is difficult to fully cover them with traditional fixed reinforcement devices; on the other hand, traditional reinforcement methods often require drilling holes on the rock surface, which not only increases the difficulty of construction, but may also cause further damage to the rock mass.
[0003] In recent years, with the continuous development of engineering technology, some new reinforcement technologies have gradually emerged. However, these technologies still have some shortcomings. For example, although some technologies can repair unloading cracks by grouting, the movement and positioning of the grouting device are relatively difficult, and it is difficult to adapt to unloading cracks of different shapes and sizes; in addition, although some technologies can realize the sliding of the grouting device, they are blocked by the protrusions of the rock surface and cannot perform precise grouting treatment at specific locations. Therefore, in response to the above technical problems, a reinforcement structure for geological slopes with unloading cracks is proposed. Utility Model Content

[0028] The surface of the slope structure 23 has a raised geological feature 24, and the raised geological feature 24 is located inside the reinforcement frame 1. There are geological fissures 25 outside the raised geological feature 24. The geological fissures 25 are unloading fissures, which are formed during the stress release and adjustment process of the rock mass, and are often caused by natural erosion or artificial excavation. These fissures are parallel to the ground surface, and the development depth can reach from several meters to more than ten meters, posing a threat to the stability of the slope and hydraulic structures. Their tortuous, discontinuous state and internal fillings reflect the complex mechanical properties of the rock mass.
[0029] The outside of the reinforcement frame 1 is fixedly connected with a mounting plate 2 , an anchor rod 3 is inserted into the upper side of the mounting plate 2 , and the anchor rod 3 is inserted into the slope structure 23 , so that the reinforcement frame 1 is installed and connected with the slope structure 23 .

The inside of the gap can be repaired simply, thereby enhancing the stability of the geological slope and ensuring the safety of construction. When grouting is carried out, the No. 2 motor 17 can be operated to lengthen the wound conduit 21. When grouting is required for a more raised rock surface or a more distant unloading crack, the conduit 21 can be extended to ensure that the repair slurry can accurately reach the target position. After the grouting is completed, the No. 2 motor 17 can be reversed to automatically reel in the conduit 21 for easy storage and carrying. The reinforcement frame 1 can be set to different lengths and widths as needed to adapt to slopes of different shapes, thereby avoiding the grouting device being blocked by the rock surface protrusions during the sliding process, thereby ensuring the smooth progress of the grouting work.
