Description

Technical Field

[0001] This utility model relates to the field of infrastructure construction, and in particular to a platform for storing crushed stone on the surface of roadside slope protection. Background Technology

[0002] Slope protection engineering refers to a series of protective measures taken to prevent damage to slopes caused by erosion or weathering from water bodies such as roads, canals, and reservoirs, as well as to prevent soil slippage and collapse that could threaten the safety of the project. Slope protection reduces the erosion of the slope by water flow, preventing soil from being carried away by water and thus protecting the slope from erosion. By increasing slope stability, slope protection can prevent soil sliding or collapse caused by rainwater infiltration or other factors. Slope protection can protect infrastructure such as roads, railways, and buildings from the impact of slope slippage, improving the safety of the project. During slope protection construction, after the earthwork is completed, a crushed stone cushion layer is laid on the slope. The crushed stone is transported by truck from the stockpile to the construction site, and then transported to the paving surface using small transport vehicles or handcarts. The problem is that the paving surface is sloping, and the crushed stone pile has poor stability and is prone to sliding down. Construction workers need to frequently intervene and maintain the paving surface, making the construction process time-consuming, labor-intensive, and posing certain safety risks.

[0018] Example 1, see appendix Figure 1-4 A roadside slope protection surface crushed stone paving and storage platform includes a supporting base frame and a platform support frame installed above the supporting base frame. The ends of the platform support frame and the supporting base frame are hinged to form a V-shaped structure. The platform support frame and the supporting base frame can be folded or opened relative to each other to change the included angle. The surface of the platform support frame is evenly provided with several platform plates 1. The bottom surfaces on both sides of the platform support frame are provided with snap-fit ​​plates 32. The snap-fit ​​plates 32 have sufficient thickness to ensure their limiting support force. Several snap-fit ​​plates 32 are evenly spaced along their length direction. A U-shaped slot 321 has a rounded chamfer at its port. A U-shaped support leg 4 is connected between the two sides of the outer end of the support base. The inner end of the U-shaped support leg 4 is rotatably connected to the side of the support base through a horizontal shaft 42. The horizontal rod 41 in the middle of the U-shaped support leg 4 corresponds to the position and size of the U-shaped slot 321 on the snap-fit ​​plate 32. The horizontal rod 41 on the U-shaped support leg 4 is snapped into the U-shaped slot 321 on the two snap-fit ​​plates 32 to achieve limiting support for the platform bracket and keep it in a horizontal support state.

[0019] A U-shaped auxiliary support leg 5 is rotatably connected between the two sides of the middle of the support base. The size of the auxiliary support leg 5 is smaller than that of the U-shaped support leg 4. The auxiliary support leg 5 is used to assist the U-shaped support leg 4 in supporting the platform support, ensuring that the platform support has sufficient support strength to bear the crushed stone.

[0020] When using the storage platform, move it to the working surface on the slope, then insert the positioning pins 22 into the holes 23 on both sides of the support frame.
