Horizontal guiding drill while-drilling acoustic wave imaging detection early warning system and detection method thereof

Abstract

The invention relates to a horizontal guiding drill while-drilling acoustic wave imaging detection early warning system which comprises an underground while-drilling detection and attitude measurementsystem and a ground data processing system that are connected with each other by a communication cable; wherein the underground while-drilling detection and attitude measurement system is installed between a drill rod on a horizontal guiding drill and a back-drawing device (or a guide plate) and comprises a while-drilling detection system and a while-drilling attitude measurement system which arerespectively connected with the communication cable, and a power supply administration module respectively connected with the while-drilling detection system and the while-drilling attitude measurement system by circuits; when in construction by using the horizontal guiding drill, construction and detection are carried out at the same time, and underground pipelines existing near the constructionlocus can be detected in real time; when in danger, the early warning system gives an alarm to operating staff of a drilling machine; meanwhile, the construction route map of the horizontal guiding drill can be accurately drawn, and the distribution situation of the pipelines existing near the construction route can be provided by combining the detection early warning information.

Description

technical field [0001] The invention relates to a horizontal directional drilling while drilling acoustic wave imaging detection and early warning system and a detection method thereof. Background technique [0002] Horizontal directional drill is a new type of trenchless construction equipment for municipal construction that has emerged in recent years. In the process of pipeline construction, it can effectively protect the original municipal construction facilities, and has little environmental damage and intervention, high construction precision and short cycle, and has been widely valued by people. At present, in the construction of urban pipelines in Shanghai, horizontal directional drilling has been widely used for construction, and obvious economic and social benefits have been achieved. [0003] For horizontal directional drilling, the construction process is "invisible", so it is necessary to accurately grasp the distribution of the original underground pipelines i...

AI Technical Summary

Problems solved by technology

We know that due to the influence of geological conditions and the deflection of the horizontal directional drill drill pipe, there will inevitably be deviations between the actual trajectory of the horizontal directional drill and the predetermined trajectory. Using geophysical prospecting equipment for subsequent detection and mapping will not be effective in terms of efficiency and accuracy. ensure
