Hydraulic Excavation System. Phase 2

Abstract

The hydraulic excavation (HYDREX) system developed during this SBIR project is capable of non-explosive excavation of hard rock in any geometry required. The system is based on a tool which discharges a pulse of extremely high pressure water into a drilled hole. The objective of the Phase II project was to develop the HYDREX concept into a practical excavation system. The first task of this project was to develop a quick opening discharge valve for the HYDREX tool. This work resulted in a poppet valve design which allows the tool to be repeatedly discharged. The prototype HYDREX tool developed in Phase II delivers a hydraulic impact greater than the most powerful impact hammers available.
