EXHAUST SYSTEM FOR DEEP WELL-TYPE DIRECT CURRENT GROUNDING ELECTRODE

WIPO Patent Application WO/2021/052001

A1

An exhaust system for a deep well-type direct current grounding electrode. A filling system is located in a deep well, and comprises: an exhaust pipe (1), coke particles (2) and a geotextile (3). The exhaust pipe (1) is fixed to the outer side of a deep well-type direct current grounding electrode (4) that extends underground, and the length of the exhaust pipe (1) is greater than the total depth of the deep well. Exhaust holes are distributed on the pipe wall of the exhaust pipe (1). The coke particles (2) are filled between the well wall of the deep well and the deep well-type direct current grounding electrode (4). The geotextile (3) is wrapped on the outer side of the exhaust holes. According to a method for constructing the exhaust system of the deep well-type direct current grounding electrode, loose flow sections of the deep well can be effectively filled, and the service life of the exhaust system is improved while efficiently exhausting gas.
