Abstract

FIELD: ecological investigations. SUBSTANCE: proposed method is based on measurement of intensity of variable magnetic field of stray current over observation lines on surface of the Earth. Horizontal component Hof magnetic field or its gradientalong vertical is measured. Position of pipe-line in plan is found by position of point of maximum Hor. Intensity of Horis measured above pipe-line at two levels over surface of the Earth and depth of lying of pipe-line is evaluated by relation of these values. Induction route finder has two induction coils connected in series or in series opposition to capacitor by means of switch and forming resonance loop in both cases. This loop is connected to narrow-band amplifier, detector and indicator connected in series. EFFECT: increased noise immunity. 2 cl, 1 dwg

на двух уровнях над поверхностью Земли и по отношению этих величин судят о глубине залегания трубопровода. Индукционный трассоискатель содержит две индукционные катушки, подсоединяемые последовательно или встречно-последовательно с помощью переключателя к конденсатору и образующие в обоих случаях резонансный контур. Этот контур подключен к последовательно соединенным узкополосному усилителю, детектору и индикатору.Purpose: increasing noise immunity. The inventive method is based on measuring the intensity of the alternating magnetic field of stray currents along observation lines on the surface of the Earth. The horizontal component of the magnetic field H y or its vertical gradient is measured

at two levels above the Earth’s surface and in relation to these values, they judge the depth of the pipeline. The induction tracing detector contains two induction coils connected in series or counter-sequentially using a switch to a capacitor and in both cases form a resonant circuit. This circuit is connected to a narrow-band amplifier, detector, and indicator connected in series.
