1.	In which method a refrigeration plant of required capacity is needed to be installed near the site of work?(a) Pumping(b) Well Point System(c) Freezing process(d) Electro osmosis processI got this question in an interview for internship.I'd like to ask this question from Deep Excavations topic in section Deep Excavations, Pile Foundations and Caisson of Construction & Building Materials
Answer» Right option is (C) Freezing process Best EXPLANATION: The PRINCIPLE of ground freezing process is the USE of refrigeration to convert in-situ pore water to Ice. Hence, refrigeration plant of required capacity is installed near the SITE of work to perform the process of refrigeration.
