Research on Wire-Line Core Drilling Combination with Water Pressure Test in Water Conservancy and Hydropower Engineering

Abstract:

the organic union of water pressure test and wire-line coring is the serious problem that must be solved, want to play the advantage of wire-line coring drilling in Water conservancy and hydropower engineering drilling.It Points out that water pressure test scheme not to extract tools can well adapt to Water conservancy and hydropower engineering drilling,through the analysis and comparison of water pressure test scheme not to extract tools and double embolization water pressure test.
