¢ Active acoustic technology that injects pulses of sound into a pipe utility. Such as pipe depth, date of installation, pipe size, and content. These can be read to obtain stored information ¢ Smart tags detectable on utilities at depths of 20 ft. Of the project, these five technologies were reduced to two for prototype development: Long-range (in excess of 10 ft) radio frequency identification (RFID) tags.ĢDetails on all five technologies and their progress are included in this report.

A scanning electromagnetic (EM) locator ģ. Pipe mapping using inserted inertial navigation devices Ģ. This project proposed research into developing five complementary technologies:ġ. On the basis of the literature review and with guidance from the TETG and the user group, Tions, and terrain/environmental issues such as traffic. Factors that make them unsuitable includeįederal Communications Commission (FCC) power and frequency restrictions, geometry restric. Nologies that are unsuitable for deep or stacked utilities.
Niques requiring technological breakthroughs were eliminated from consideration, as were tech. The goal of this R01C project is development of near-term solutions. Of these techniques require a large amount of development to make them usable for application in The literature search discovered 24 possible technologies available to detect and map utilities. Taken by the projects was a literature search. (TETG) and user group for guidance and feedback on direction. Additionally, the two projects had a common technical expert task group Some activities of the two projects were conducted together and jointly analyzed in order
Ment Using Multisensor Platforms, to avoid duplication and provide a complementary set of The R01C project worked closely with the R01B project, Utility Locating Technology Develop. Of the locatable zoneâ might produce a larger return on investment to the transportation The SHRP 2 R01C project proceeded with the concept that âinnovations to improve the extent It is more likely that these shallower utilities,ĭifficult to locate, would be more frequently impacted by highway construction. Utilities that prove difficult to locate there are also utility systems that are hidden or maskedīy those utilities that reside on top of them. Result, there was a slight realignment in goals to include the concept that it is not always deep Niques based on vacuum-excavated boreholes.â This recommendation garnered a low priorityīecause of its expected technological difficulty and probable low return on investment. TheseĬould include direct-path detection methods deployed from inside a utility or cross-bore tech. That target deep utilities that currently cannot be detected by surface-based approaches. Ing and Characterizing Underground Utilities, was âthe development of locating technologies One of the recommendations from the SHRP 2 R01 study, Encouraging Innovation in Locat.
