Ecological wetland buffering system along high-speed rails

Abstract

The invention relates to an ecological wetland buffering system along high-speed rails. A constructed wetland system is built in isolation lands along the high-speed rails and comprises a rammed earth layer, a stuffing mix layer, a water inlet channel and a water outlet channel, the rammed earth layer is paved on the isolation lands along the high-speed rails, a waterproof layer is paved on the rammed earth layer, drainage grooves are paved on the waterproof layer, an ecological stuffing layer and the stuffing mix layer are sequentially paved on the drainage grooves, a water distribution main pipe and a water distribution branch pipe are erected on the stuffing mix layer, the water distribution branch pipe communicated with the water distribution main pipe is transversely arranged in a radial mode, plant carriers are paved on the water distribution main pipe and the water distribution branch pipe, plants are planted on the plant carriers, the water distribution main pipe is communicated with the water inlet channel through a pipeline, the drainage grooves are connected with the water outlet channel through water outlet pipes, and the water outlet channel is connected with an ecological pond through a recycling water pipe. A sound shielding board is distributed on the isolation lands along the high-speed rails, and a sound vibration measuring apparatus is installed on the sound shielding board. The ecological wetland buffering system is used for processing sewage, absorbing sound, lowering noise and reducing vibration on the surface of the earth.

Description

technical field [0001] The invention relates to an ecological wetland buffer system used along high-speed railways for sewage treatment, rainwater reuse, sound absorption and noise reduction, effective use of land, and surface vibration buffering, and belongs to the technical fields of environmental protection engineering and water treatment technology. Background technique [0002] The high-speed rail buffer zone is a flexible and diverse ecological sewage treatment system and sound absorption and noise reduction system that utilizes the combination of various functional components, and can design different forms of treatment units along the high-speed rail according to different terrains and the conditions of surrounding buildings, saving construction costs , improve efficiency, reduce energy consumption, and improve the function of sound absorption and noise reduction. It combines the functions of sound absorption and noise reduction and artificial wetland treatment. Con...
