Well cover assembly for pipe-containing ground pavement of sponge city

Abstract

The invention discloses a well cover assembly for pipe-containing ground pavement of a sponge city. The well cover assembly comprises a well cover base and an upper well cover installed on the well cover base, wherein the well cover base comprises an upper well cover frame seat, a drainage layer and an inner well cover placing groove seat, the upper well cover frame seat is provided with an upperwell cover placing hole, the drainage layer is provided with a water collecting hole, an annular water collecting groove is formed in one circle on the side wall of the drainage layer, a plurality ofdrainage holes are formed in the bottom of the water collecting groove in the circumferential direction, a connecting well hole is formed in the inner well cover placing groove seat, a hollow layer isarranged in the horizontal direction of the inner well cover placing groove seat, the projection area of the hollow layer in the vertical direction is larger than the projection area of the connecting well hole in the vertical direction, an inner well cover is arranged in the hollow layer of the inner well cover placing groove seat, and a plurality of inner well cover hollowed holes and slag discharging seams are formed in the inner well cover. The drainage layer is communicated and matched with the urban pipe-containing ground, the pavement integrity of the urban pipe-containing ground is guaranteed, the drainage layer is not influenced by a rainwater well and a sewage well, a double-layer well cover structure prevents pedestrians from falling, and the well cover assembly is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of well cover drainage, and in particular relates to a well cover assembly used for laying pipe-containing ground in a sponge city. Background technique [0002] At present, in order to solve the problem of urban waterlogging in my country and improve the waterlogging performance of sidewalk surfaces, people have developed various sidewalk floor tile pavement structures containing pipelines, such as Chinese patents CN204875442U, CN207828739U, CN209602894U and so on. For this type of pavement floor tiles, the continuous splicing of the bricks is required to effectively ensure the drainage function of the inner pipe. Under normal circumstances, the rainwater pipe network and sewage pipe network are often arranged under the sidewalk surface. In this type of sidewalk pavement, due to the layout of rainwater wells and inspection wells, the continuity of the connection between the brick inner pipes is destroyed, a...

AI Technical Summary

Problems solved by technology

Under normal circumstances, the rainwater pipe network and sewage pipe network are often arranged under the sidewalk surface. In this type of sidewalk pavement, due to the layout of rainwater wells and inspection wells, the continuity of the connection between the brick inner pipes is destroyed, and the manhole cover and manhole cover components. The impermeability of the side affects the smooth flow of water in the brick, resulting in a decrease in the drainage performance of the floor tile
