abstract

Quality control and quality assurance during horizontal directional drilling installations (HDD) is a topic that is gaining increasing interest and concern in the engineering community as HDD is becoming a mainstream construction technology. The paper describes a method for increasing the transparency of pulled-in-place trenchless installations using an array of sensors mounted within a protective casing, located ahead of the pipe product pull head. The data collected by the sensors, including pull-load and borehole pressure, is stored on a memory chip placed onboard the platform, thus creating a permanent electronic record of the installation. This data can be used by contractors, consultants and owners for quality control purposes and the improvement of design models and construction practices. In addition, real-time information can be provided to the operator, giving him/her the opportunity to detect potential problems in a timely manner so that appropriate mitigation measures can be taken.
