Abstract

The invention discloses a flexible barrier having restoration and vertical obstruction functions. The flexible barrier having the restoration and vertical obstruction functions comprises a restoration functional portion and a vertical obstruction portion. The restoration functional portion comprises two layers of nonwoven geotextile and a restoration functional material layer placed between the two layers of nonwoven geotextile. The vertical obstruction portion is composed of HDPE geomembrane. The vertical obstruction portion is fixed to the outer side of one of the two layers of nonwoven geotextile of the restoration functional portion. The flexible barrier having the restoration and vertical obstruction functions is established in the manner that the restoration functional portion and the HDPE geomembrane are combined, the problems that a traditional vertical anti-seepage barrier do not have the restoration function, and a permeable reactive barrier do not have the vertical obstruction function are solved, and the flexible barrier having the restoration and vertical obstruction functions has the advantages of being simple in construction, good in anti-seepage effect, good in restoration function and the like.

Description

technical field [0001] The invention relates to the fields of groundwater seepage prevention and environmental restoration, in particular to a flexible barrier with restoration and vertical barrier functions and its preparation and application. Background technique [0002] With the rapid development of my country's industry, environmental pollution is also becoming more and more serious. The storage yards, heap leaching sites, and tailings ponds of some chemical and mining companies lack effective anti-seepage measures, resulting in industrial waste (liquid), chemical products, slag, etc. polluting the soil and groundwater, seriously endangering people's livelihood. environment to survive. [0003] The permeable reaction wall technology based on nano-zero-valent iron filling has been widely used in the remediation treatment of groundwater containing heavy metals, petroleum hydrocarbons, and nitroaromatic compounds. Osmotic reaction wall restoration technology has the adva...
