UNIVERSAL FLEXIBLE PROTECTIVE CONCRETE QUILL Russian patent published in 2008 - IPC E01C5/06 E02B3/12 

FIELD: construction, road construction.

SUBSTANCE: invention relates to road construction, particularly to construction of pavements, and can as well be used in hydraulic construction. The universal flexible protective concrete quill consists of concrete blocks, joined together one after the other and in rows by flexible cables. In the upper part the blocks are in the form of rectangular parallelepipeds, and in the lower part they are in the form of truncated pyramids with an inclination angle of the edges between 20° and 45°. The base sides of the truncated pyramids are smaller than the sides of the rectangular parallelepipeds with value equal to the minimum diameter of the curved circle of the cable. The height of the truncated pyramids is less than or equal to the height of the rectangular parallelepipeds. The preferred dimensions of the blocks are 400×400×300 mm. Together with provision of effective installation and high service characteristics, the proposed universal flexible protective concrete quill considerably lowers injury cases among pedestrians when used as topping for pavements.

EFFECT: possibility of fast installation of the quill; reduced injury cases among pedestrians.
