摘要： A method for mapping a bore below a ground surface is provided. A boring rod head configured to transmit a signal indicating the pitch angle of the boring rod head with respect to a horizontal plane is disposed within a bore. The boring rod head is advanced within the bore in predetermined linear increments. The pitch angle is measured at each increment. The change in depth is determined at each increment from a prior increment based on the length of the increment and the measured pitch angle at the increment. For each increment, the changes of depth determined in the prior step are added, including the change of depth for the most recent increment. Thus, the depth of the bore at each increment with respect to a predetermined horizontal plane is determined. The depths determined in the prior step are then adjusted by an amount equal to the difference between the predetermined horizontal plane and a ground surface above the bore at each increment so that the adjusted depth at each increment describes the depth of the bore with respect to the ground surface at that increment. The adjusted depth data is accumulated.

摘要： A system for mapping horizontal bores below a ground surface is provided. A transmitting source radiates a location signal from a bore. The bore may be a newly dug bore or a bore containing an existing utility. A receiver device receives a location signal and indicates, responsively to the location signal, the lateral position of the horizontal bore with respect to the receiver device. A measurement device measures the depth of the bore with respect to the ground surface at selected locations along the bore. A monitor device receives the depth data from the measurement device, compiles the depth data associated with the selected locations with respect to at least one reference position, and outputs the compiled depth data so that the depth of the bore at the selected locations may be collectively identified.

摘要： A system and method for locating a horizontal bore below a ground surface includes a transmitting source configured to radiate from the bore a dipole magnetic field aligned with the bore. A receiver is located remote from the transmitting source and has a first coil and a second coil. Each coil defines an axis, wherein the axes of the first coil and the second coil are orthogonal to each other. A measurement device is in communication with the coils and configured to measure the phase of signals induced on the coils by the magnetic field when the axis of the first coil is horizontally perpendicular to the axis of the magnetic field and the axis of the second coil is vertically perpendicular to the axis of the magnetic field. The measurement device is also configured to determine the lateral position of the transmitting source relative to the coils responsively to the phase of the signals on the first coil and the second coil.

摘要： A boring head of a boring tool for boring the ground includes a device for detecting inclination of the boring head therein. The device includes a roll angle sensor and a pitch angle sensor. The roll angle sensor detects an angular position of the boring head in a roll direction and outputs a roll angle detecting signal. The pitch angle sensor detects an angular position of the boring head in a pitch direction outputs a pitch angle detecting signal. A signal modulating circuit converts the roll angle detecting signal and the pitch angle detecting signal into a serial signal and modulates the serial signal. An output circuit receives the modulated serial signal and outputs a magnetic field which is receivable by a receiver located on the ground and which permits determination of the roll angle and the pitch angle of the boring head.

摘要： A system and method for fault detection including a transmitter adapted to transmit a composite signal on a buried cable so that fault leakage of the composite signal returns to the transmitter through the ground surrounding the buried cable. The composite signal is composed of a low frequency first component that alternates at a first frequency and that defines a phase, and a low frequency second component that alternates at a second frequency higher than the first frequency and that defines a duty cycle having a predetermined relationship with the phase of the first component. A receiver receives the composite signal from the probe and filters the first component, filters the second component, defines an alternating reference signal having a phase based on the duty cycle of the filtered second component, and compares the phase of the reference signal with the phase of the filtered first component.
