Document Type and Number:
WIPO Patent Application WO/2021/051978
Kind Code:
A1
Abstract:
Disclosed is a coke mixed liquid for a deep-well-type direct-current grounding electrode. In the coke mixed liquid, the ratio of the weight of coke particles to the weight of water is not greater than 1:1, and the particle diameter of the coke particles is 0.1 mm to 0.2 mm. According to the filling method for the coke mixed liquid for a deep-well-type direct-current grounding electrode, the coke mixed liquid can be effectively subjected to filling, and at the same time, the exhaust performance of an exhaust system of a deep-well-type direct-current grounding electrode can be guaranteed. Further disclosed is a filling method for the coke mixed liquid for a deep-well-type direct-current grounding electrode. The coke mixed liquid for a deep-well-type direct-current grounding electrode fills, in a hole-bottom grouting manner, a deep well by means of a hollow feed steel pipe extending to the downhole.
