PARFECT soil stabilization equipment can transfer the soil binder through the air compressor to the mixing head which is mounted on the excavator, and mix with the soil to improve the strength of the foundation.Learn more about in situ soil stabilization Because of the lag of soil pollution, and there are many difficulties in the identification and monitoring of soil pollutants in the past, the problem of land pollution has been paid less attention in the past. The relocation and abandonment of industrial enterprises is the product of accelerated urbanization in China in recent years. The relocation of polluting enterprises has been vigorously implemented in various large and medium-sized cities, such as Beijing, Tianjin, northeast old industrial bases, the Yangtze River Delta and the Pearl River Delta.

The environmental problem of contaminated land has become an obstacle in the process of land redevelopment. At present, some old industrial districts located in cities cannot be redeveloped due to pollution problems, so they are very concerned by governments and enterprises in recent years.

Based on the strong support of national policies, soil remediation industry is gradually emerging. According to the data released by the foresight Industry Research Institute, in September 2013, the number of domestic enterprises engaged in soil remediation reached more than 300. In 2014, there were about 500 enterprises in the soil remediation market and up to more than 1000 in 2016.

At present, the most popular soil remediation in China is the remediation of contaminated sites. Because of the expansion of the urban area, the former industrial and mining enterprises have gradually become urban construction land, but the pollution left over by the industrial and mining enterprises is urgent to be harnessing, and the site restoration has become the focus of the industry. The market of arable land restoration began to grow as the importance of ensuring the quantity of arable land, and improving the quality of cultivated land was gradually implemented.

In the soil remediation enterprises, almighty enterprises can carry out pollution site investigation, risk assessment, repair construction and so on. Business basically covers the various links of soil remediation, and has a more competitive advantage. It has become the biggest beneficiary of the development of the industry.

In recent years, more and more soil stabilized projects in China have been growing rapidly, and have become the leading technology. Engineering amount from hundreds of cubic meters to several million cubic meters of soil, soil stabilization technology is not only applied in the remediation of contaminated soil, but also has become an important technology for sediment treatment of river pollution. Soil stabilization technology has been applied to heavy metal contaminated soil and sediment, such as Hg, Pb, CD and as, and is applied in the sediments contaminated by PAHs and pesticides. The technology of chemical oxidation and stabilization combined to repair organic polluted river sediment has also been applied. The stabilized soil and sediment are used in landfill disposal, site barrier and used as subgrade material.

At present, most of the soil stabilization projects in China are implemented by stabilizing technology. There are few works on solidification technology, which is in sharp contrast with the technology adopted by the US super fund contaminated sites. Solidification can stabilize and encapsulate pollution at the same time. It has no direct exposure to human body, and the long-term environmental safety is better than stabilization. Stabilization plays a stabilizing role in pollutants. The stabilization effect is influenced by soil properties, pollutant types and external environment. The uncertainty of long-term environmental safety is large. However, due to the stable repair technology, including the selection of stabilizing materials and the mixture of agents and soil, the technology is simple and the solidification time is short. Because of the complex technology, strict process requirements, long maintenance time and great influence on the temperature, the solidification technology has influenced the enthusiasm of the remediation enterprise. In addition, although in situ solidification technology does not require the process of soil excavation, transportation and disposal, it has significant economic advantages, and at the same time, because of the overall solidification block, it is less affected by external environment, and its environmental risk is smaller. However, the soil remediation technology of contaminated sites is still mainly based on heterotopic technology. In situ stabilization treatment is only several cases. The main reason is that in situ solidification will affect the future use of the site, and it is not easy to combine with site development.
