2. by medicament retracting device, for the characteristic of powder medicine, take negative pressure extraction method, effectively prevent medicament for the pollution of environment and waste.
3., by multilamellar three-dimensional blade and along the particular design such as spray-hole of blade uniform stationing, the mixing efficiency of medicament and contaminated soil can be improved.
4. this invention adapts to multiple stratum and the pollution of different depth, pollutes particularly with the deep layer within hard soil layer and more than 5 meters 20 meters and has a clear superiority in.
5. this invention can carry out normal construction, at the contaminated site that level of ground water is higher under und rained condition, it is not necessary to carries out engineering dewatering in advance.
