[0017] The technical scheme in the utility model is further explained below in combination with the drawings and embodiments.
[0018] As Figure 1 The utility model discloses a highway drainage ditch structure, including the drainage ditch body 1 of the same direction setting of along highway roadbed 2 side, in this embodiment, drainage ditch body 1 adopts concrete pouring, makes the vertical section of drainage ditch body 1 "concave" type groove structure. The lowest point of drainage ditch body 1 inside bottom end position is lower than roadbed 2, in order to collect the rainwater overflowed on the road surface.
[0019] In this embodiment, the outer side of the two opposite inner walls of the drainage ditch body 1 is provided with a plurality of groups of intermittently distributed limiting pieces, wherein each group of limiting pieces includes two oppositely arranged limiting blocks 3, the limiting block 3 is an arc-shaped tapered surface, the height of the limiting block 3 corresponds to the height of the drainage ditch body 1, and the thickness gradually decreases from top to bottom, forming a structure that protrudes inwardly. In this way, the drainage ditch body 1 forms a narrow-top wide-bottom structure, and the small opening at the top makes it more difficult for soil and rocks to fall into the interior of the drainage ditch body 1. When facing small mountain landslides or soil falling, the problem of blockage caused by large stones falling into the interior of the drainage ditch is reduced.
[0020] As Figure 2 As shown in the drawings, the limiting block 3 has an arc-shaped protruding shape that protrudes inwardly in the middle and gradually fits the inner wall of the drainage ditch body 1 on both sides along the extension direction of the drainage ditch body 1, so that the water flow passing through the limiting piece is reduced while being restricted in the area below the drainage ditch body 1. Because the limiting pieces are intermittently distributed inside the drainage ditch body 1, the flow rate of the water flow is fast at times and slow at times, which can form a more intense scouring effect on the inner wall of the drainage ditch body 1, so that a small amount of soil entering the drainage ditch body 1 can be stripped from the inner wall of the drainage ditch body 1 and washed away by the water, avoiding blockage caused by long-term soil accumulation.
[0021] In a further embodiment, the limiting component also includes a diversion plate 4 disposed between the two limiting blocks 3. The diversion plate 4 is a vertically arranged plate-like structure, with a height not less than half the height of the drainage ditch body 1 and not higher than the drainage ditch body 1. The diversion plate 4 is parallel to the extension direction of the drainage ditch body 1 and is positioned precisely at the center of the bottom surface of the drainage ditch body 1. The diversion plate 4 forms two parallel channels within the limiting component, further guiding the water flow to accelerate its velocity and flushing the inner wall of the drainage ditch body 1 behind it, preventing soil deposition caused by the water flow slowing down after passing through the limiting component. Additionally, the bottom of the diversion plate 4 is provided with several through holes 41 extending to both sides. The through holes 41 connect the spaces on both sides of the diversion plate 4 and are evenly distributed along the bottom of the diversion plate 4. The through holes 41 allow rainwater flowing in from both sides of the drainage ditch body 1 to form a transverse water flow, laterally flushing the areas on both sides of the diversion plate 4, further reducing the problem of soil deposition and accumulation.
[0022] Preferably, in this embodiment, the limiting block 3 and the drainage ditch body 1 are separate structures, and the limiting block 3 and the drainage ditch body 1 are connected by a one-way detachable load-bearing component. That is, the limiting block 3 cannot be manually disassembled after installation, and the limiting block 3 and the drainage ditch body 1 have a load-bearing limit. When subjected to pressure exceeding the load-bearing limit, the limiting block 3 will separate from the side of the drainage ditch body 1.
[0023] like Figure 3 As shown, in the specific solution, the side of the drainage ditch body 1 is provided with several vertically distributed connecting grooves 11. The connecting grooves 11 are recessed towards the inside of the drainage ditch body 1, and a vertically raised baffle 12 is provided near the side wall of the drainage ditch body. The limiting block 3 is equipped with several connectors 31 corresponding to the connecting grooves 11 on the inner wall side of the drainage ditch body. The connectors 31 have a hook-like structure that extends horizontally and then bends vertically downward, allowing them to extend into the connecting groove 11. After being placed downward, they form a locking structure with the baffle 12. In this way, the limiting block 3 can be hung on the inner wall of the drainage ditch body 1 through the locking structure, and then the limiting block 3 can be kept stable by gravity. Because the baffle 12 is also a concrete structure, it has a certain upper limit of bearing capacity. When a large amount of soil and rocks fall onto the limiting block 3 due to a landslide, the limiting block 3 is subjected to huge pressure exceeding the upper limit of bearing capacity, causing the baffle 12 to break and the connection between the limiting block 3 and the inner wall of the drainage ditch body 1 to detach. Then, because the top of the limiting block 3 is thicker, it tilts to the opposite side under the action of gravity, eventually forming a high-compression-resistant shielding structure that is tilted inside the drainage ditch body 1, leaving space for water to flow through below, thereby preventing the drainage ditch body 1 from being completely blocked by soil and rocks, maintaining a certain drainage effect, and further maintaining the function of the drainage ditch.
[0024] Further, after the connecting piece 31 is clamped with the baffle 12, a gap exists between the limiting block 3 and the side wall of the drainage ditch body 1, and the gap is filled with a concrete connecting layer 5. The connecting layer 5 can strengthen the connection of the limiting block 3, and avoid problems such as loosening, accidental breakage of the baffle 12, etc.
[0025] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the technical solutions of the present application, and all should be covered in the scope of the claims of the present application.
