Technical Field

[0001] This utility model belongs to the field of cathodic protection test pile technology, specifically a small cathodic protection test pile structure with protective function. Background Technology

[0002] Gas pipelines are laid underground year-round, and regular testing is usually required to understand their usage. However, some pipelines are laid in the carriageways of existing or planned roads, creating "roadside test piles." Problems such as "the inability to extend cathodic protection test piles to both sides of the road," "impact on the urban landscape," and "poor waterproofing performance of test wells and test piles" have become unsolvable challenges for urban gas companies, hindering the construction and safe operation of urban gas pipelines.

[0003] However, most existing test piles are directly fixed underground, which makes them prone to water accumulation, thus reducing their service life and the overall scope of application of the device. In addition, existing test piles require personnel to enter the well during testing, resulting in poor testing results. To address these issues, this invention designs a small cathodic protection test pile structure with protective functions. Utility Model Content
