Drainage structure of sunken plaza and construction method thereof

Abstract

The invention relates to a drainage structure of a sunken plaza, and belongs to the field of building construction. The structure comprises a bottom plate, a water storage ditch and a retaining wall,multiple sets of flood discharge areas are mounted on the bottom plate in an evenly spaced manner, each flood discharge area comprises multiple drainage grooves formed in the bottom plate, the multiple drainage grooves are formed in the same straight line, a top plate is arranged in each drainage groove, the size of the top plates is matched with the size of the drainage grooves, the top faces ofthe top plates are flush with the top face of the bottom plate, a confluence pipe is arranged between two adjacent sets of flood discharge areas, and is located below the bottom plate, a drainage opening is formed in the inner side wall of each drainage groove, the drainage openings communicate with drainage pipes, the ends, away from the drainage grooves, of the drainage pipes communicate with the confluence pipe, drive devices used for driving the top plates to move to the positions of the drainage openings are arranged in the drainage grooves, and the drainage structure has the effect of conveniently improving the flood discharge capacity.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a drainage structure of a sunken square and a construction method thereof. Background technique [0002] The sunken square is a kind of urban leisure square. It is an enclosed open public space. The whole or part of the sunken square sinks into the surrounding environment. The difference between it and the ground square is mainly reflected in the sense of enclosure of the space. , plane form, ground design and safety. The sunken square is now known as one of the methods of making open space in high-density central cities. In the design of the sunken plaza, its drainage structure design is one of the most important links. [0003] The existing application publication number is the Chinese patent of CN110258624A, which discloses a sunken square drainage structure and its construction method, including a base plate and a retaining wall arranged on the edge of the bas...

Problems solved by technology

[0004] The above existing technical solutions have the following defects: the rainwater enters the storage ditch through the cover plate for storage, and penetrates into the planting soil through the transfer sponge in the recovery pipe to protect the moisture of the planting soil, but when the rainfall is large, the storage The water in the ditch may not be able to discharge quickly, causing flooding in the square and even causing losses to businesses in the square
