Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage engineering, in particular to a hidden rainwater outlet. Background Art

[0002] In addition to meeting the function of traffic passage, urban road design also requires the layout of various municipal pipelines under the municipal roads to maintain the basic living needs of urban residents. This leads to a variety of ancillary structures under the urban roads, resulting in various types of manhole covers or covers in the carriageway, sidewalk, and green belt.

[0003] Different types of manhole covers or covers are located on the pavement of urban roads, which not only affect the comfort of pedestrians and the appearance of the road surface, but also the uneven force on the road around the manhole cover often causes the road surface and roadbed around the manhole cover to be damaged, resulting in the manhole cover sinking, damage or abnormal noise. Among them, there are many rainwater grates on the pavement of urban roads, which are located on both sides of the road, not only affecting the comfort of driving and parking, but also easily causing garbage to accumulate at the rainwater outlet, seriously affecting the appearance of urban roads.

[0004] At present, when most domestic designers design road storm drains, most of them use side ditch type storm drains, and the storm drain grates appear directly on both sides of the road, or a few use vertical grate type storm drains, but there is still the problem of storm drain inspection manhole covers, and the aesthetics is worse. Therefore, more research is needed on how to solve such problems and improve the overall texture of the road.

[0005] At present, there are few examples in China on how to achieve effective drainage and concealment of rainwater outlets on urban roads. The present invention develops a hidden rainwater outlet, which, by providing a vertical water collecting device and an invisible U-shaped cover, reasonably coordinates the positional relationship between the rainwater outlet and the road curb, thereby realizing the removal of manhole covers from the rainwater outlet, greatly improving the appearance of the road and the comfort of driving.
