電極体の埋設形態
Document Type and Number:
Japanese Patent JP7075651
Kind Code:
B2
Abstract:
To provide a burial method for electrode body capable of providing anticorrosive effect of a long term underground burial piping by preventing increase of grounding resistance in an electrode body for electrical protection, and a burial jig for electrode body.SOLUTION: An electrode body for electrical protection of underground burial piping is buried by penetrating the same through a concrete wall 23, in which an open hole 23a is formed in the concrete wall 23, the electrode body is housed in a casing part 17 in a burial jig 15 having a base end part 16, the casing part 17 connected detachably to the base end part 16 at a rear end, and an acute part 18 connected detachably to a front end of the casing part 17, pushing pressure is loaded on the base end part 16 to push the burial jig 15 into ground through the open hole 23a from an underground pit, and the base end part 16 and the casing part 17 are extracted at a state that the electrode body is positioned in the ground to leave the acute part 18 and the electrode body in the ground.SELECTED DRAWING: Figure 3
