SYSTEM OF GUTTERS Russian patent published in 2015 - IPC E01C11/22 

FIELD: construction.

SUBSTANCE: system of gutters comprises three elements made of polymer material and connected to each other - a receiving socket, a gutter made of sections and a draining socket with a sprinkler attachment. In the cross section the gutter and sockets have flat bottom and boards inclined outside. Receiving and draining sockets have inclined sections for joining with overlap to a gutter at the angle of road embankment inclination. Boards and bottoms of all three elements from outside are reinforced with transverse stiffening ribs, sections of the gutter are equipped with anchor elements in the form of rods. To each other the elements are connected as overlapping by means of metal fastening elements. All elements are made from polymer composite material by means of layering. The inner layer of the elements comprises light-stabilising additives, and the outer one is made from fireproof resin. Transverse stiffening ribs are made as solid with layering. Sections are connected to each other as overlapping by means of a bolted connection from stainless or carbon steel. The receiving socket in the intake part is equipped with a rib deepened into soil. In the lower part the gutter is equipped with longitudinal ribs-anchors that connect to each other the lower side parts of the transverse stiffening ribs. Anchor elements in the form of rods are installed into the embankment with the possibility of transverse ribs thrusting against them.

EFFECT: provision of gutter strength, reliability of their joints and prevention of their unfixing.
