[0002] During dam construction, every step requires meticulous control to ensure the smooth progress and safety of the entire project. One crucial and indispensable task is installing rockfall barriers around the construction site. These barriers are vital for preventing rocks of varying sizes and shapes from accidentally falling from the dam under construction. The barriers effectively block the path of these falling rocks, and even if a rock slips, it will be firmly intercepted, preventing it from falling below the construction area and causing serious injury or damage to workers, equipment, and other related facilities. Existing rockfall barriers are typically installed on the ground at the base of the dam, making them unsuitable for installation on slopes and limiting their flexibility. Utility Model Content

[0024] 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.

[0025] like Figures 1-5 As shown, the anti-rolling stone guardrail for reservoir dam construction in this embodiment includes a base and a box body 1. The base includes a bottom plate 2 and an arc-shaped support 3. The bottom plate 2 has fixing holes 4 on its edge. By setting fixing cones, anchor rods, or expansion bolts 8 in the fixing holes 4, the bottom plate 2 is fixed to the flat ground or slope. The arc-shaped support 3 is fixed to the top surface of the bottom plate 2. The box body 1 is located above the bottom plate 2 and covers the outside of the arc-shaped support 3. A rotating shaft 5 is provided at the front end of the bottom of the box body 1. An ear plate 6 is provided on the outside of the box body 1 and is rotatably connected to the rotating shaft 5. The ear plate 6 is fixed to the top surface of the bottom plate 2. The rotating shaft 5 and the center of the arc-shaped support 3 are collinear. A connecting plate 7 is fixed at the rear end of the bottom of the box body 1 and behind the arc-shaped support 3. The connecting plate 7 is connected to different positions of the arc-shaped support 3 by bolts 8. A baffle 9 is provided inside the box body 1.

[0026] In this embodiment, multiple arc-shaped supports 3 are provided, and the multiple arc-shaped supports 3 are equally spaced along the length direction of the base plate 2. The lower end of the arc-shaped support 3 is fixed to the top surface of the base plate 2, specifically by welding or bolts 8. A connecting inclined plate 10 is provided between the upper end of the arc-shaped support 3 and the top surface of the base plate 2. The lower end of the connecting inclined plate 10 is fixed to the top surface of the base plate 2, specifically by welding or bolts 8; the upper end of the connecting inclined plate 10 is fixedly connected to the upper end of the arc-shaped support 3, specifically by welding or bolts 8.

[0027] A connecting plate 7 is located at the rear end of the housing 1 and behind the arc-shaped support 3. Both ends of the connecting plate 7 are fixedly connected to the inner wall of the housing 1. The connecting plate 7 is also arc-shaped, and its front side contacts the rear side of the arc-shaped support 3. Bolt holes 8 are provided at positions corresponding to the connecting plate 7 and the arc-shaped support 3. In this embodiment, the arc-shaped support 3 has multiple connecting holes 16, which are circular and evenly distributed. Bolts 8 pass through the bolt holes 8 and the corresponding connecting holes 16, thereby connecting the connecting plate 7 to the arc-shaped support 3. By connecting the connecting holes 16 at different positions with bolts 8, the angle between the housing 1 and the base plate 2 changes. When the housing 1 and the base plate 2 are at a right angle, the anti-rolling stone guardrail can be installed on flat ground. Adjusting the angle between the housing 1 and the base plate 2 facilitates the installation of the anti-rolling stone guardrail on a slope, ensuring that the housing 1 is always vertical or nearly vertical, thus intercepting rolling stones.

[0028] In another embodiment, such as Figure 6 As shown, the arc-shaped support 3 has a connecting groove 17, which is a long strip structure. The bolt 8 passes through the connecting groove 17 and connects to the connecting plate 7.

[0029] In this embodiment, a pull plate 12 is provided at the top front end of the box 1, and a pull rope 13 is connected to the pull plate 12. A ground nail 14 is provided at the end of the pull rope 13 away from the pull plate 12. Specifically, the two ends of the pull rope 13 are respectively tied to the pull plate 12 and the ground nail 14. The ground nail 14 is inserted into the ground or slope and keeps the pull rope 13 taut, thereby making the box 1 more stable.

[0030] In this embodiment, the lower part of the baffle 9 has a rearward concave arc-shaped structure, with the upper and lower ends of the arc-shaped structure located at the front and rear ends of the housing 1, respectively. The upper part of the baffle 9 has a vertical flat plate structure, with the upper end extending to the top of the inner side of the housing 1. A protective net 11 is provided on the front side of the baffle 9, and the protective net 11 is connected to the inner side wall of the housing 1. The protective net 11 is inclined, with the upper end of the protective net 11 closer to the rear end of the housing 1 than the lower end. Preferably, the protective net 11 is an elastic net. By providing a protective net 11 on the front side of the baffle 9, when falling rocks arrive, the protective net 11 first intercepts the falling rocks, effectively buffering the impact of the falling rocks on the baffle 9, thereby forming a double interception structure and enhancing the impact resistance of the anti-rolling stone barrier in this embodiment.

[0031] In this embodiment, a stiffening plate 15 is provided at the rear end of the housing 1, and multiple stiffening plates 15 are arranged sequentially from top to bottom.

[0032] The working principle of the anti-rolling stone guardrail used in the construction of the reservoir dam in this embodiment is as follows:

[0033] By setting an arc-shaped support 3 on the base, and setting a rotating shaft 5 and a connecting plate 7 on the box body 1, and the connecting plate 7 can be connected to the arc-shaped support 3 at different positions by bolts 8, the angle between the box body 1 and the bottom plate 2 can be adjusted. When the box body 1 and the bottom plate 2 are at a right angle, the anti-rolling stone guardrail can be installed on flat ground. Adjusting the angle between the box body 1 and the bottom plate 2 makes it easy to install the anti-rolling stone guardrail on a slope, so that the box body 1 is always in a vertical or nearly vertical state, thereby intercepting the rolling stones.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
