Abstract The present invention relates to a drain bole fibre bundle ooze-guiding method and its equipment. It includes the following steps: 1. drilling holes on defined position of engineering rock-soil body according to the defined bore size and length; 2. preparing plastic pipes; 3. making plastic pipe into perforated pipe; 4. placing the fibre bundles into the perforated pipe and making all fibre bundles axially distribute along drilled holes; and 5. placing the perforated pipe into the above-mentioned drilled hole and fixing it. Said invented method can make water continuously ooze out along all fibre bundles so as to can greatly reduce kinetic water pressure and static water pressure and can retain the stability of slopping engineering and underground engineering.
