Description
Technical field
The invention belongs to soil and underground water based technique for in-situ remediation fields, and in particular to a kind of soil and underground water are in situ single
Repair system and method are stirred in axis major diameter injection.
Background technology
Increasingly the situation is tense with underground water pollution for China's soil, and industrial sites pollution problem protrudes, and there is an urgent need for carry out to repair to control
Reason.Contaminated site is relatively conventional and has a large capacity and a wide range, and involved pollutant includes heavy metal, volatile organic matter（VOCs）, half
Volatile organic matter（SVOCs）And total petroleum hydrocarbon（TPH）.Especially VOCs and SVOCs have volatility, toxic, concealment,
The features such as cumulative bad, diversity is typical high risk pollutant, is easy to cause nearby residents health and environmental quality huge
Long-term damage, social demand and the market demand for carrying out repairing and treating be huge.
Soil and groudwater remediation pattern is divided into in-situ immobilization and showering, and there are larger contaminations for showering
Risk causes secondary pollution, and more demanding to construction site, and some are located at the contaminated site of developed area often not
Has such condition.Showering is deeper in pollution depth, may relate to base pit dewatering, excavation and supporting, special
It is not east China soft clay area, engineering construction risk is high.And in-situ immobilization is in the feelings that do not carried to soil and groundwater
It completes under condition, has a clear superiority under the conditions ofs using site area anxiety etc..
Chemistry redox technology is proved to be able to reach preferable removal effect to the pollutant in water and soil, by chemical oxygen
Change reduction to be combined with in-situ immobilization pattern, there is relevant art in the market：Geoprobe direct press types high-pressure injection, shaft building note
Enter, High-pressure Spiral Spray Technology etc..But there is also some problems for these technologies, for example it is difficult to adapt to miscellaneous fill place, shaft building cost
It is high, complicated for operation, it is difficult to ensure mixing evenness etc., ensure that water and soil is sufficiently mixed with medicament, simplifies construction technology, improves and construct
Efficiency is that this technology is successfully crucial.
Existing stir in situ technology has more application in base pit engineering water-stop curtain and local stiffening, passes through jet cement
Slurry construction water-stop curtain, water-stop curtain permeability can reach 10-7Cm/s, mixing evenness can be guaranteed.
