Description
Technical Field
[0001] The utility model relates to the technical field of urban infrastructure, in particular to a concrete ditch cover and a prefabricated mold. Background Art
[0002] With the rapid development of cities, the construction standards of road drainage facilities in some urban areas are low, the time of operation is long, and the drainage facilities have been damaged to varying degrees. In order to solve urban waterlogging and improve urban management capabilities and quality image, it is necessary to transform and upgrade urban infrastructure construction.
[0003] In the process of drainage facility construction, the existing technology adopts water collection wells for drainage ditches. By setting collection ports at intervals on the cover plate of the drainage ditch, rainwater on the ground can be concentrated into the water collection wells through the collection ports. Although this collection method can ensure the cleanliness of the road surface to a certain extent, in areas or seasons with relatively concentrated rainfall, rainwater may not flow into the drainage ditch in time, resulting in water accumulation on the road surface, affecting the passage of vehicles and pedestrians. Especially when the rainfall is heavy, when the collection ports are blocked by floating objects such as ground debris and garbage, a small number of collection ports will be blocked, which will cause serious water accumulation and even cause waterlogging, seriously affecting the normal use of drainage facilities.
[0004] In addition, due to the adoption of the above-mentioned confluence setting method, the existing drainage ditch cover and other parts of the ground adopt an integral concrete pouring construction method, and only the location where the confluence or manhole cover is set is an openable cover. When maintaining the drainage ditch, the manhole cover or cover is opened to carry out unblocking and silt removal work.
[0005] Therefore, how to increase the speed of rainwater convergence, eliminate road surface waterlogging, and avoid waterlogging has become an issue that needs to be focused on during urban road construction and drainage facility construction. Utility Model Content
[0006] At least one of the purposes of the invention of the utility model is to provide a concrete ditch cover and a prefabricated mold to address the problem that the existing drainage ditches are prone to clogging and serious water accumulation due to the centralized arrangement of confluence outlets during construction. The concrete ditch cover is continuously laid on the top of the drainage ditch as a whole, and multiple rows of drainage holes are arranged on each concrete ditch cover, so that rainwater from the road surface can be discharged from any part of the drainage ditch into the drainage ditch, and then concentratedly drained through the drainage ditch to the rainwater accumulation well for centralized treatment.
[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model includes the following aspects.
[0008] A concrete ditch cover comprises a square main structure, and a plurality of rows of drainage holes are arranged along the length direction of the square main structure. The plurality of rows of drainage holes are strip holes extending along the width direction of the square main structure. A connecting seam groove is also reserved at the end of the length direction of the square main structure, so that a long strip connecting seam is formed when two adjacent concrete ditch covers are spliced.
[0009] After multiple rows of drainage holes are arranged on the concrete ditch cover, the top of the drainage ditch is paved with the concrete ditch cover of the present application within the entire length to form a drainage ditch top plate, which can prevent rainwater on the road from flowing and gathering on the road for a long time, ensure that rainwater on the road can be discharged into the drainage ditch from any part, and improve the drainage ditch confluence capacity. At the same time, after multiple rows of drainage holes are arranged, the bearing strength of the concrete ditch cover will not be affected, ensuring the safety of vehicles and pedestrians on the road.
[0010] By using the end connecting seam groove in the length direction of the square main structure, after the concrete ditch cover of the present application is used within the overall length range on the top of the drainage ditch, two adjacent concrete ditch cover plates can be spliced together to form a long strip connecting seam, which can, on the one hand, play a drainage role together with the drainage holes to enhance the drainage capacity of the drainage ditch top plate; on the other hand, it is convenient for the disassembly and installation of the concrete ditch cover plate, and for the maintenance work such as deblocking and silting of the drainage ditch.
[0011] As a preferred solution of the utility model, the concrete ditch cover has two rows of drainage holes, and the drainage holes are strip-shaped oblong holes.

The drainage hole boss is set as a hollow structure, so that during the demolding process, the concrete trench cover prefabricated mold has better flexibility and deformation ability, further facilitates the separation of the concrete trench cover from the mold, and improves the demolding ability.
[0020] As a preferred solution of the utility model, the top of the drainage hole boss is provided with a strip-shaped small hole for eliminating the residual stress of the mold. The provision of the strip-shaped small hole can eliminate the influence of the residual stress of the mold, so that the trench cover plate made by the mold has higher precision and less deformation, thereby improving the prefabrication quality of the concrete trench cover plate.
[0021] Furthermore, two small holes are arranged on both sides of the top of the drainage hole boss.
[0022] As a preferred solution of the utility model, the edge of the concrete ditch cover prefabricated mold is provided with an extended skirt, and the height of the drainage hole boss is consistent with the depth of the sinking groove. The extended skirt can increase the width of the mold edge surface, and combined with the drainage hole boss that is consistent with the depth of the sinking groove, it is convenient to use tools such as scrapers to smooth the surface of the concrete ditch cover prefabricated mold during the process of prefabricating the ditch cover, thereby ensuring the manufacturing accuracy of the ditch cover and facilitating the operation of the scraper.
