FIELD: water supply engineering.
SUBSTANCE: invention concerns devices for water collection and drainage from road surface and can be applied in development of yards, public and private gardens, parks etc. Claimed concrete gutter chute includes horizontal support surfaces in upper part, carrying cartridges forming horizontal support surfaces for metal grate at the outer surface. Internal lengthwise sides feature holes holding inset parts out of steel sheets in the form elongated plate with holes oriented along the chute side, with upper edges bent inwards by 90°. The chute features coaxial hole matching hole in the base of cartridges, and rack strip notching bent to the same direction as plate edge; together they form hollow for tie bolt of metal grate fixation. Each part features lengthwise side walls with anchor elements in the form of lugs with holes for fixture elements. Bent edge of each inset part has flanged mouth in respective hole in the base of cartridges. Bent plate edge and rack strip together with side walls of inset part form hollow holding a nut for tie bolt of metal grate fixation to prevent nut slipping.
EFFECT: enhanced rigidity of concrete gutter chute due to the inset part design and fixation in the chute.
