Urban sinking corridor landscape wetland

Abstract

The invention discloses an urban sinking corridor type landscape wetland. It includes a pool body, a medium pool and a plant pool. The cross section of the pool body is an inverted trapezoid, and the side wall is provided with hard impermeable pavement; the medium pool and the plant pool are arranged at intervals in the pool body. Purify the water body through the series structure of the medium pool and the plant pool, increase the landscape benefit and ecological service function; the narrowing from wide to narrow increases the kinetic energy of the river water body, increases the contact area between the water body and the atmosphere interface, increases reoxygenation, and improves the entire corridor wetland The self-purification ability of the structure; the permeable structure at the bottom of the pool increases the filtration, purification and infiltration of surface runoff, and promotes the purification of groundwater quality.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to an urban sunken corridor-style landscape wetland. Background technique [0002] With the acceleration of the urbanization process and the increase in the number of motor vehicles, the road surface accumulates a large amount of pollutants such as suspended particles, nutrients, heavy metals and polycyclic aromatic hydrocarbons through vehicle exhaust emissions, tire and road wear, and oil leakage. During urban rainfall and snowfall, the pollutants accumulated in the air and on the road surface are leached, washed, and engulfed by rainwater, forming urban road surface runoff, which migrates to the receiving water body through the urban pipe network system with the water flow, and affects the receiving water body. It will cause obvious damage to the water quality and affect the aquatic ecological environment. Surface runoff from urban roads is the second largest sourc...
