Description
Technical field
The application belongs to Electromagnetic Survey of Underground Pipelines field, specifically, is related to a kind of super buried depth Electromagnetic Survey of Underground Pipelines device.
Background technology
Underground pipeline finder is that pipeline owner and pipeline management department are used for buried pipeline position and bury native depth detection
Instrument, its principle be using reception antenna in ground detection underground utilities specific electromagnetic field signal, according to the change of signal
Law determines the position of underground utilities, and measure pipeline according to the signal difference of upper and lower two horizontal antennas buries native depth.
Underground pipeline finder in the market using reception antenna be all fixed on inside receiver, in ground no-dig technique situation
Under, the depth of buried pipeline is measured, this method is due to being limited by apparatus structure, therefore the spacing of upper and lower two antennas is received
Limit, the scope for fathoming also is limited, and upper and lower two antennas receive the signal difference very little on buried pipeline, when signal it is micro-
It is weak to receiver be difficult to differentiate when, the depth of buried pipeline also cannot just be measured.The depth survey scope of conventional pipeline survey meter
Within being 0-5 rice, but developing rapidly with no-dig technique Directional Drilling Technology, got over using the underground utilities of Directional Drilling construction at present
Come more, and buried depth be also increasingly deeper, river crossing, highway pipeline now with buried depth met or exceeded
30 meters, using common detection methods, due to the signal difference by upper and lower two coils, very little can cause so deep pipeline
Measurement error is very big, or even detect is full of prunes information.In order to ensure super buried pipeline depth and position measurement essence
Degree, needs to measure using indirect method, and at present conventional indirect method is exactly to use near target pipeline with quiet
Electric feeler inspection method bores detecting deep well.But the problem that the method is present is, using which type of rapier, how will smoothly to visit very much
Pole is put in bored deep-well, and ensures that rapier can be moved freely in deep-well, and this is the difficult problem run in Site Detection.
Another question be drilling well detection can not direct measurement buried pipeline bury native depth, need by collection site data,
Later stage manually calculate just can determine that pipeline bury soil depth.
