Abstract

The invention discloses a sustained-release soil heavy metal repair pile foundation comprising a pile foundation body, a sealing cover and filtering cloths. The pile foundation body is of a structurewith the sealed bottom and the hollow interior. The pile foundation body is internally provided with a heavy metal decomposer. The pile foundation body comprises an external pile foundation main body,a shallow pile foundation main body and a deep pile foundation main body which are arranged from top to bottom. Filtering holes are formed in the outer surfaces of both the shallow pile foundation main body and the deep pile foundation main body correspondingly. The sealing cover is located at the top end of the pile foundation body and matched with the external pile foundation main body. The filtering cloths are located on the outer surfaces of both the shallow pile foundation main body and the deep pile foundation main body. According to the sustained-release soil heavy metal repair pile foundation, heavy metal contaminated soil can be repaired continuously, and due to the simple structure, the sustained-release soil heavy metal repair pile foundation can be used for repair of the heavymetal contaminated soil on a large scale.

Description

Technical field [0001] The invention relates to a soil restoration technology, in particular to a slow-release soil heavy metal restoration pile foundation. Background technique [0002] With the development of society and economy, more and more land has been put into use. While a large amount of land has been put into use, it has also caused various soil pollution. At present, societies in various countries are paying more and more attention to environmental issues. Remediation of the contaminated soil is urgent. [0003] Among the current soil pollution, heavy metal pollution is particularly serious. The main sources of heavy metal pollution are the three wastes discharged by industrial and mining enterprises such as mining, metallurgy, and ore processing, the burning of fossil fuels such as coal and oil, and the excessive use of fertilizers and pesticides, which mainly include Mercury, cadmium, lead, chromium, zinc, copper, nickel and metal-like arsenic, etc. Heavy metals are ...
