Description
Technical Field
[0001] This utility model is a riverbank protection device, belonging to the field of water conservancy construction. Background Technology
[0002] During river construction, edge protection is of paramount importance. It not only concerns the safety of construction workers, but effective edge protection can also prevent accidents such as falls and falling objects, ensuring the safety of the surrounding environment. Among edge protection measures in river construction, guardrails are a very common facility. Typically, guardrails are installed along the edge of the river with their bottoms buried to prevent accidents such as accidental falls.
[0003] However, in the actual process of river construction, the geological conditions at the riverbank are often complex and unstable. The combined effects of construction disturbances, water erosion, and other factors make the riverbank highly susceptible to collapse. Since the anchorage of the guardrail is limited to the riverbank, it loses its stable support when the riverbank collapses. In this situation, the guardrail can easily fall into the river along with the collapsed soil. Once the guardrail falls into the river, it is not only difficult to lose and retrieve, but it is also highly likely to be damaged during the fall and by the impact of the river current, rendering it unusable. This seriously affects the effectiveness of the edge protection and poses a significant safety hazard to construction. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a river construction edge protection device to solve the problems mentioned in the background technology. This utility model prevents the guardrail from falling into the river and being lost or damaged when the river edge collapses.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a river construction edge protection device, comprising a guardrail, with two legs installed at the bottom of the guardrail, and a horizontal plate installed between the two legs. Both ends of the horizontal plate are fitted with L-shaped plates for burying in the ground via fasteners formed by multiple sets of screws and first nuts. Ear plates are installed on the lower surface of the horizontal portion of the L-shaped plates. A first through hole is provided on one side of the ear plate, and a screw is inserted into the first through hole. A U-shaped plate for burying in the ground is provided on one side of the L-shaped plate, and a second through hole is provided on one side of the U-shaped plate. The end of the screw away from the ear plate passes through the second through hole, and a second nut is threadedly connected to one end of the screw on both sides of the first through hole. A third nut is threadedly connected to the end of the screw away from the ear plate on both sides of the second through hole.
[0006] Furthermore, a limiting plate for limiting the position of the screw head is installed on the upper surface of the horizontal part of the L-shaped plate. There is a gap between the limiting plate and the vertical part of the L-shaped plate. One end of the screw passes through the limiting plate, the vertical part of the L-shaped plate and the horizontal plate and is threaded with a first nut.
[0007] Furthermore, a reinforcing plate is installed on the lower part of one side of the limiting plate facing the vertical part of the L-shaped plate, and the end of the reinforcing plate away from the limiting plate is connected and fixed to the vertical part of the L-shaped plate.
[0008] Furthermore, multiple vertical pipes connected and fixed to the guardrail are evenly arranged inside the guardrail, and multiple horizontal pipes connected and fixed to the guardrail are evenly arranged inside the guardrail, with the horizontal pipes penetrating the vertical pipes.
[0009] Furthermore, a first support plate is provided on one side of the ear plate, and there is a gap between the first support plate and the ear plate. The first support plate is installed on the lower surface of the horizontal part of the L-shaped plate, and the screw passes through the first support plate. The first support plate and the ear plate are arranged between two second nuts on a screw.
[0010] Furthermore, a second support plate is installed on one side of the lower surface of the U-shaped plate, and a vertical part of the U-shaped plate and the second support plate are disposed between two third nuts on a screw.
[0011] Furthermore, the outer surface of the support leg has an opening, the cross plate passes through the opening, and a base plate is installed at the lower end of the support leg.
[0012] The beneficial effects of this utility model are:
[0013] 1. By installing L-shaped plates at both ends of the horizontal plate between the bottom legs of the guardrail and connecting the L-shaped plates and U-shaped plates with screws, the L-shaped plates and U-shaped plates are buried deep underground, expanding the anchoring range of the guardrail in the ground. When the geological conditions are unstable and the river edge collapses, the U-shaped plates can provide additional anchoring force to prevent the guardrail from falling into the river with the collapsed soil, reducing the risk of loss and damage.
[0014] 2. Adjust the spacing between the U-shaped plate and the L-shaped plate. At this time, the relative position of the screw and the U-shaped plate and the L-shaped plate will change. Then, use two second nuts to limit the relative position of the screw and the L-shaped plate, and use two third nuts to limit the relative position of the screw and the U-shaped plate, so that the U-shaped plate is away from the edge of the river, and the distance between the U-shaped plate and the guardrail can be adjusted according to the condition of the river edge.
[0015] 3. After the screw and the first nut are assembled, the screw is exposed between the vertical part of the limiting plate and the L-shaped plate. This makes it easy to separate the screw and the first nut by sawing off the screw later, which facilitates the smooth separation of the L-shaped plate and the horizontal plate. At the same time, the screw rod can be sawed off by using the gap between the first support plate and the ear plate or by using the gap between the second support plate and the vertical part of the U-shaped plate, which facilitates the easy separation of the screw rod from the L-shaped plate and the U-shaped plate.

Detailed Implementation
[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] Please see Figure 1 and Figure 2This utility model provides a technical solution: a river construction edge protection device, including a guardrail 1, wherein a plurality of vertical pipes 2 are evenly arranged inside the guardrail 1 and connected and fixed to the guardrail 1, and a plurality of horizontal pipes 3 are evenly arranged inside the guardrail 1 and connected and fixed to the guardrail 1, the horizontal pipes 3 penetrating the vertical pipes 2, two support legs 11 are installed at the bottom of the guardrail 1, and a horizontal plate 9 is installed between the two support legs 11, wherein the outer surface of the support legs 11 has an opening, the horizontal plate 9 penetrating the opening, and a base plate 10 is installed at the lower end of the support legs 11, the base plate 10 increasing the contact range between the support legs 11 and the ground.
[0026] See Figures 1-6 Both ends of the horizontal plate 9 are fastened with L-shaped plates 6 for burying in the ground by fasteners formed by multiple sets of screws 4 and first nuts 12. A limiting plate 5 for limiting the position of the screw head is installed on the upper surface of the horizontal part of the L-shaped plate 6. There is a gap between the limiting plate 5 and the vertical part of the L-shaped plate 6. One end of the screw 4 passes through the limiting plate 5, the vertical part of the L-shaped plate 6 and the horizontal plate 9 and is threaded to the first nut 12. A reinforcing plate 18 is installed at the lower part of the side of the limiting plate 5 facing the vertical part of the L-shaped plate 6. The end of the reinforcing plate 18 away from the limiting plate 5 is connected and fixed to the vertical part of the L-shaped plate 6. The reinforcing plate 18 improves the mechanical strength of the connection between the limiting plate 5 and the L-shaped plate 6. After the assembly of the screw 4 and the first nut 12 is completed, the part of the screw 4 located between the limiting plate 5 and the vertical part of the L-shaped plate 6 is not covered and is exposed. This design is ingenious. When it is necessary to separate the L-shaped plate 6 from the horizontal plate 9, if the screw 4 and the first nut 12 are difficult to separate by conventional tightening, the exposed screw 4 can be used to cut it off with a saw. In this way, the L-shaped plate 6 and the horizontal plate 9 can be easily separated. The operation is simple and convenient, greatly improving the efficiency of maintenance and replacement of related parts, and reducing construction costs and difficulty.
[0027] See Figures 1-6An ear plate 15 is installed on the lower horizontal surface of the L-shaped plate 6. A first through hole is opened on one side of the ear plate 15, and a screw 7 is inserted into the first through hole. A U-shaped plate 8 for burying in the ground is provided on one side of the L-shaped plate 6. A second through hole is opened on one side of the U-shaped plate 8. The end of the screw 7 away from the ear plate 15 passes through the second through hole. A second nut 13 located on both sides of the first through hole is threaded to one end of the screw 7. A third nut 17 located on both sides of the second through hole is threaded to the other end of the screw 7 away from the ear plate 15. At the bottom of the guardrail 1, a horizontal plate 9 is connected between two support legs 11. L-shaped plates 6 are installed at both ends of the horizontal plate 9. During installation, the L-shaped plate 6 is deeply buried in the ground, and the screw 7 is used to connect the L-shaped plate 6 to the U-shaped plate 8, which is also deeply buried in the ground. This design greatly expands the anchoring range of the guardrail 1 in the ground and enhances the overall stability. In actual river construction environments, geological conditions are often complex and varied. When encountering unstable geological conditions and riverbank collapses, the U-shaped plate 8 plays a crucial role. It provides additional anchoring force, firmly holding the guardrail 1 in place, effectively preventing it from falling into the river with the collapsed soil. This significantly reduces the risk of loss or damage to the guardrail 1, ensuring the integrity and safety of the edge protection facilities. Furthermore, the spacing between the U-shaped plate 8 and the L-shaped plate 6 can be adjusted according to the actual conditions of the riverbank. During adjustment, the relative positions of the screw 7 with the U-shaped plate 8 and L-shaped plate 6 will change accordingly. After adjustment, tightening the two second nuts 13 on the side of the screw 7 located on the L-shaped plate 6 restricts the relative position of the screw 7 with the L-shaped plate 6; tightening the two third nuts 17 on the side of the screw 7 located on the U-shaped plate 8 restricts the relative position of the screw 7 with the U-shaped plate 8. This allows for easy adjustment of the U-shaped plate 8 to be closer to or further away from the river edge, enabling the distance between the U-shaped plate 8 and the guardrail 1 to be flexibly changed according to the site conditions, further enhancing the applicability of the protective device.
[0028] See Figures 1-6A first support plate 14 is provided on one side of the ear plate 15, with a gap between the first support plate 14 and the ear plate 15. The first support plate 14 is installed on the lower surface of the horizontal part of the L-shaped plate 6, and the screw 7 passes through the first support plate 14. The first support plate 14 and the ear plate 15 are positioned between two second nuts 13 on the screw 7. A second support plate 16 is installed on one side of the lower surface of the U-shaped plate 8, and a vertical part of the U-shaped plate 8 and the second support plate 16 are positioned between two third nuts 17 on the screw 7. To facilitate the subsequent disassembly of the screw 7 from the L-shaped plate 6 and the U-shaped plate 8, a first support plate 14 is provided on one side of the ear plate 15 on the lower surface of the horizontal part of the L-shaped plate 6, with a certain gap reserved between the first support plate 14 and the ear plate 15; at the same time, a second support plate 16 is installed on one side of the lower surface of the U-shaped plate 8, with a gap between the second support plate 16 and a vertical part of the U-shaped plate 8. These two gaps play an important role when it is necessary to disassemble the screw 7 from the L-shaped plate 6 and the U-shaped plate 8. Workers can use the gap between the first support plate 14 and the ear plate 15 to saw off the screw 7, thus easily separating the screw 7 from the L-shaped plate 6. Similarly, by utilizing the gap between the second support plate 16 and the vertical part of the U-shaped plate 8, the screw 7 can also be easily sawed off, completing the separation of the screw 7 from the U-shaped plate 8. This design greatly simplifies the disassembly process, improves the efficiency of construction and maintenance, and reduces unnecessary work difficulty and time costs.
