Coke mixture liquid of deep well type DC grounding electrode and filling method thereof

Abstract

The invention discloses a coke mixture liquid of a deep well type DC grounding electrode. The ratio of the weight of coke particles to the weight of water is not more than 1: 1 in the coke mixture liquid. The particle size of the coke particles is 0.1 mm-0.2 mm. The invention discloses a coke mixture liquid filling method of the deep well type DC grounding electrode. The coke mixture liquid is enabled to be effectively filled, and the exhaust performance of the exhaust system of the deep well type DC grounding electrode can also be guaranteed. The invention also discloses a filling method of the coke mixture liquid of the deep well type DC grounding electrode. The coke mixture liquid of the deep well type DC grounding electrode fills into the deep well through the hollow feed steel pipe extending to the underground by the way of hole bottom slurry pressing.

Description

technical field [0001] The invention relates to the technical field of deep well grounding electrodes, in particular to a coke mixture filling method for deep well type DC grounding electrodes. Background technique [0002] Coke, as the main filling material for the gap between the downhole feeder rod and the well wall, is an important part of the grounding electrode. However, there are ionic conduction in the actual feed conductor in the process of scattering. In the process of ion conduction, the interaction between coke and water will be accompanied by the generation of gas. If the gas cannot be discharged smoothly from the downhole feeder system, the gas will adhere to the feeder system in the form of bubbles; as the amount of gas continues to increase , the grounding resistance will increase accordingly, eventually leading to the failure of the grounding electrode. [0003] Therefore, there is a need for a filling method for the coke mixture of the deep well type dire...
