METHOD FOR JOINING DAM TO LANDSLIDE WATER SIDE SLOPE Russian patent published in 1996 - IPC

FIELD: water development works. SUBSTANCE: pioneer prism 5 is made in tail race on immovable bottom 2 of river 3 at slope foot 4 and along it. Integrity of landslide massif 7 is broken in head race directly at dam 1 under construction by cutting trench slot filled with binding soil of soft or flowing-soft consistency. The trench length is oriented along motion of landslide massif 7. Integrity of massif 7 is broken in tail race by forming vertical drain slot in massif 7. The slot is oriented towards the motion of landslide massif 7. Drain slot is formed concurrently with shooting charges placed in tiers over well depth with provoking landslide shifts in water side slope 4. As a result rest 21 is formed under protective prism 5. EFFECT: landslide preventing. 4 cl, 4 dwg
