At the same time, the ranging leg assemblies 2 on both sides can facilitate people to measure the buried depth of the top of the pipeline 4 (i.e., the actual measured elevation value of the ranging leg assembly + the thickness of the curved plate = the buried depth of the top of the pipeline), thereby realizing accurate measurement of the pipeline slope and elevation (such as buried depth).
