BANK PROTECTION, SLOPE PROTECTION AND RETAINER HOLDING FACILITY Russian patent published in 1995 - IPC

FIELD: water-development works. SUBSTANCE: bank protection, slope protection and retainer holding facility has facing slabs 1-1′ of rectangular or square configuration with reinforced films made of polymer materials rigidly embedded in each frame 2 over perimeter. Slabs 1-1′ adjoin one another longitudinally and are coupled and rigidly secured both to front profiled bars 4 of abutment frames 5-5′ and relative to one another by means of anchor ties and inserted parts by the tops of each of adjacent slabs 1-1′ and in middle portion along their length 7. Front profiled trapezoidal bars 1 are rigidly secured to similar lower bars 9 and rear bars 10 by means of ties; bars 4, 9 and 10 are engageable relative to one another by their end fins on the side of their constricted faces and form in each abutment row (in the section of the facility) abutment frames 5-5′ mounted in succession in vertical plane and adjoining each other by end fins of widened faces 16 of engageable lower bars 9 and rear bars 10. Front bars 4 of frames 5-5′ and facing slabs 5′ are oriented in plane of slope 17. Lower abutment frames 1-1′ of each row are deepened to non-washable depth - below the level of low waters with facing slabs 1′ mounted on them. Lower bars 9 are coupled together by their widened faces 16. Each row of abutment frames 5-5′ is mounted in the slops cut beforehand in slope 17. Joints of adjacent slabs 1-1′ are embedded in cement and slots with abutment frames 5-5′ mounted in them are filled with local or draining soil. EFFECT: enhanced reliability. 3 cl, 11 dwg
