Research Progress of Dike Leak Rescue Technology

Leaks refer to seepage holes running through a dike body or foundation, the formation of which may pose dire threats safety and cause breaching due large flow rate strong scouring force. Once water inlet leak is detected, sealing rescue measures should be taken in accordance with principle “inlet plugging outlet anti-filtration”. The key quick filling stability materials. Herein, technology leaks systematically laid out; causes development mechanism are analyzed; detection, plugging, summarized; future research direction clarified. Existing equipment complicated time-consuming. Hence, methods innovated improved effectively improve efficiency success emergency rescues. A new concept “grade-by-grade sealing” correspondingly proposed for leaks, changing rescues from “single-level at inlet” portal inside leak”. tandem closed space formed leak. hydrodynamic pressure changed independent bearing gradual materials
