DRAINAGE CHANNEL ELEMENT AND LATTICE LOCK FOR IT

FIELD: drainage system.SUBSTANCE: invention relates to the elements of drainage channels and a bolt-free lattice lock on a tray for collecting and draining water from ground road surfaces in a drainage system. The element of a drainage channel consists of tray 2, lattice 3 and lattice lock 4. Tray 2 has bottom 5, lateral longitudinal sides 6 with horizontal supporting surfaces 7. Niches 8 are made in the upper part of tray 2 on its inner side of side walls 6, open to the inside of tray 2. Niche 8 has supporting upper edge 9. Vertical holes 10 are made from the side of supporting surfaces 7. Along the longitudinal edges of lattice 3 opposite niches 8 of tray 2, there are recesses 14 with supporting guide protrusions 15. Lattice lock 4 is made of an elastic material and has support head part 16, in which grooves 17 are made with supporting surfaces corresponding to the surfaces of supporting guide protrusions 15 made in recesses 14 of lattice 3. Head part 16 of lock 4 is equipped with console 18, on the free movable lower end of which fixing protrusion 19 is made, in contact with supporting upper edge 9 of tray 2 niche 8. Additional guide protrusion 20 is made in head part 16 of lattice lock 4 on the opposite side of console 18, oriented perpendicular to the supporting surfaces of head part 16 of lattice lock 4, located in vertical holes 10 and 12 of tray 2. On console 18 of lattice lock 4 on the opposite side of fixing protrusion 19, protrusion 23 with vertical hole 24 for dismantling tool 25 can be made.EFFECT: technical result is ensuring reliable fixation of the lattice to the tray body in all planes, as well as simplifying the process of both installation and removal of the lattice from the tray.10 cl, 22 dwg Изобретение относится к элементам водоотводных каналов и к безболтовым фиксаторам решеток на лотке, предназначенных для сбора и отвода воды с наземных дорожных покрытий в системе водоотвода. Технический результат - обеспечение надежной фиксации решетки на корпусе лотка во всех плоскостях, а также упрощение процесса как установки, так и съема решетки с лотка. Элемент водоотводного канала содержит лоток 2, решетку 3 и фиксатор решетки 4. Лоток 2 имеет дно 5, боковые продольные стороны 6 с горизонтальными опорными поверхностями 7. В верхней части лотка 2 на его внутренней стороне боковых стенок 6 выполнены ниши 8, открытые во внутреннюю часть лотка 2. Ниша 8 имеет опорную верхнюю кромку 9. Со стороны опорных поверхностей 7 выполнены вертикальные отвер
