Description

Technical Field

[0001] The utility model specifically relates to a sand-based water seepage well cover with warning function. Background Art

[0002] Sponge city construction is an important way to enhance urban value and realize ecological civilization and the construction of a beautiful China. As an important measure for sponge city construction, permeable pavement is widely used in urban roads, communities, squares, parking lots and other areas. These areas need to install rainwater wells and sewage wells, and use them with manhole covers to achieve strong water absorption, permeability and water seepage.

[0003] Traditional manhole covers are mostly made of cast iron or prefabricated concrete, and generally use large-pore water-permeable methods. The pores are easily clogged and the water permeability is short. In actual construction, problems such as alkali fracture and severe water accumulation have occurred. The connection between the cover and the manhole ring is mostly a one-point hinged connection or no connection. As urban roads are prone to waterlogging, rainwater wells, sewage wells and other problems, the cover is easily displaced or lost due to upwelling water or other external forces, causing traffic accidents and personal injury accidents.
