Liftable waterlogging-preventing drainage type sidewalk slab paving structure and control method thereof

Abstract

The invention discloses a liftable waterlogging-preventing drainage type sidewalk slab paving structure and a control method thereof. The liftable waterlogging-preventing drainage type sidewalk slab paving structure is arranged on one side of a common sidewalk and comprises drainage sidewalk slabs, drainage ditches, liftable support columns and a rainwater pipeline, wherein the drainage sidewalk slabs, the drainage ditch, the liftable support column and the rainwater pipeline are paved in a length direction; each drainage sidewalk slab is arranged above the corresponding drainage ditch; each liftable support column is arranged just below the corresponding drainage sidewalk slab and can automatically extend and retract up and down according to the height of the water level in the drainage ditch so as to lift or lower the corresponding drainage sidewalk slab; the side walls of the drainage ditches are connected with the rainwater pipeline through connecting pipes; and a water level monitoring device is arranged above the side walls, which are away from the common sidewalk, of the drainage ditches. During use, the height of the water level of the common sidewalk is monitored by the water level monitoring device, so that whether the corresponding liftable support columns need to be lifted so as to lift the corresponding drainage sidewalk slabs to the position above the water levelis determined. According to the liftable waterlogging-preventing drainage type sidewalk slab paving structure, pedestrians are ensured to safely and conveniently pass through in heavy rain or accumulated water, and the phenomenon that the pedestrians walk in rainstorm is avoided.

Description

technical field [0001] The invention relates to the technical field of urban road drainage, in particular to a liftable anti-waterlogging and drainage type sidewalk slab pavement structure and a control method thereof. Background technique [0002] The pavement structure of the existing sidewalk is cement concrete sidewalk slab plus cement mortar, cement concrete base, gravel sand cushion and natural soil structure. The 2% cross slope of the sidewalk is used to let the water flow naturally to the roadway with a lower elevation, and then pass through the roadway. The rainwater outlet on the road enters the rainwater pipe and is further discharged. [0003] During severe rainstorms, due to the insufficient instantaneous drainage capacity of rainwater outlets and rainwater pipes, it is easy to accumulate water on the sidewalk, and the water depth is sometimes as high as 5cm to 10cm or even higher, which brings great inconvenience to pedestrians on the sidewalk. , Wet shoes and...

Problems solved by technology

[0003] During severe rainstorms, due to the insufficient instantaneous drainage capacity of rainwater outlets and rainwater pipes, it is easy to accumulate water on the sidewalk, and the water depth is sometimes as high as 5cm to 10cm or even higher, which brings great inconvenience to pedestrians on the sidewalk. , wet shoes, wet pants, easy to slip and wrestle, affecting personal health and safety

[0004] Therefore, how to solve the problem of water accumulation on the sidewalk during heavy rain or water accumulation has become a technical problem urgently needed by those skilled in the art
