Title:
EMBEDDED BRANCH LINE STRUCTURE OF BRANCH LINE SUPPORTING ELECTRIC POLE, AND LAYING METHOD OF EMBEDDED BRANCH LINE
Document Type and Number:
Japanese Patent JP2023068252
Kind Code:
A
Abstract:
To provide a branch line structure which prevents an embedded branch line embedded in the ground from being corroded or electrolytically corroded for a long period of time or even broken, and which can be constructed at a low cost by a safe, reliable and easy work by using a hard case-like concrete coating member having a high insulating effect so as to prevent an embedded branch line from directly contacting the soil and causing electric corrosion.SOLUTION: An embedded branch line structure of a branch line supporting an electric pole includes: a stay block 3 having an anchor portion 4; a steel pipe-like embedded branch line rod 7 embedded in the ground of a branch line 1 connected to the stay block 3 and supporting an electric pole; and a cylindrical coating member 10 for coating the embedded branch line rod 7 in the ground. The coating member 10 is formed of a concrete member, has a structure capable of insulating the steel pipe-like embedded branch line rod 7 from electric current in the ground and has a structure capable of not damaging the embedded branch line rod 7 due to external pressure in the ground.SELECTED DRAWING: Figure 1
