[0017] In order to further understand the purpose, structure, characteristics and functions of the present utility model, the following is a detailed description in conjunction with the embodiments.
[0018] Please refer to Figure 2 , the precast U-shaped groove concrete greening drainage ditch of an embodiment of the present utility model includes a main body of the ditch 2, a baffle 3, and a filter screen 1.
[0019] As Figure 4 shown, the main body of the ditch 2 is in a "U" shape, the main body of the ditch 2 is made of concrete, and an upper part of the inner wall of the main body of the ditch 2 is provided with a fixing groove 201. The fixing groove 201 is in a square structure and penetrates through the left and right end faces of the main body of the ditch 2.
[0020] As Figure 3 shown, the baffle 3 is in a trapezoidal structure, the baffle 3 opens upward, a plurality of partition plates 304 are provided at the bottom of the baffle 3, the partition plates 304 are perpendicular to the bottom of the baffle 3, and fixing members 303 are provided at the left and right edges of the upper end of the baffle 3. The fixing members 303 are connected to Figure 4corresponding to the fixed groove 201 shown, two middle parts at the left and right ends of the baffle 3 are respectively provided with an arc-shaped flow guide plate 302, the arc-shaped flow guide plate 302 opens downward, and a water outlet 301 is arranged at the lower end of the arc-shaped flow guide plate 302.
[0021] As Figure 1 shown, a layer of filter screen 1 is arranged at the upper end of the ditch main body 2.
[0022] Preferably, the diameter of the mesh holes of the filter screen 1 is less than 2 CM. The filter screen 1 can effectively intercept the solid waste larger than 2 CM in the drainage ditch, ensuring the drainage efficiency of the drainage ditch.
[0023] Preferably, the distance from the water outlet 301 to the arc-shaped flow guide plate 302 is less than the distance between the upper and lower ends of the arc-shaped flow guide plate 302. The arc-shaped baffle 302 can be effectively used to discharge the solid waste to the middle area of the baffle 3, avoiding the solid waste directly entering the water outlet 301 and thus blocking the drainage ditch.
[0024] Preferably, the width of the water outlet 301 is less than 1 CM. The water outlet 301 can intercept the solid waste larger than 1 CM inside the baffle 3, further improving the drainage efficiency of the drainage ditch.
[0025] Preferably, a sawtooth structure is arranged at the lower end of the water outlet 301. The sawtooth structure can improve the efficiency of intercepting solid waste and ensure the drainage efficiency of the drainage ditch.
[0026] Preferably, the filter screen 1 is fixed on the ditch main body 2 by screws. Fixing the filter screen 1 on the ditch main body 2 can prevent the filter screen 1 from shifting on the ditch main body 2, thus affecting the drainage efficiency of the drainage ditch, and is convenient for removing the filter screen 1 later.
[0027] Preferably, the partition plate 304 is flush with the lower end of the water outlet 301. The partition plate 304 can intercept the solid waste inside the baffle 3 while not affecting the drainage of the water outlet 301.
[0028] During use, first pour the concrete into the mold to form the ditch main body, then horizontally set two fixed grooves on the inner wall of the ditch main body, then fix the baffle on the ditch main body through the fixing parts and the fixed grooves, and finally fix the filter screen on the upper surface of the ditch main body by screws. During drainage, the filter screen will roughly block the solid waste outside the drainage ditch, and at the same time the baffle will play a secondary filtering effect, leaving the solid waste at the bottom of the baffle. When the water level in the baffle reaches a certain level, the sewage can be discharged into the drainage ditch through the water outlet.
[0029] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
