冻结法环保性探讨

Freezing method as an outstanding reinforcing method has been widely used in underground project.Currently low carbon is increasingly popular, freezing method does less harm to environment has been widely accepted, and considering environmental protection is an important direction of the underground engineering.But this point only sees the surface of underground engineering and neglects the fact when the big freeze equipment run long time consuming a lot of energy. Here I do some discussion by examples to show the pollution of artificial freezing. Underground engineering's future is not only low pollution on surface, but low pollution and low carbon in the whole process.
