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.
