TRAY FOR SYSTEMS OF WATER COLLECTION AND REMOVAL FROM THE ROADWAY Russian patent published in 2020 - IPC E01C11/22 

FIELD: drains.

SUBSTANCE: invention represents an element of surface water discharge channel and is intended for collection and removal of water from ground road pavements in drainage system. Tray 1 for systems for collection and removal of water from the roadway is made in the form of a solid monolithic body - an elongated straight parallelepiped with side walls, a bottom and an upper part. Inside the central part of the tray body there is longitudinal partition 6, which forms with the side walls of the tray two internal longitudinal channels having an oval profile. Partition 6 in cross section together with profiles of upper part of tray and its bottom 4, which are arranged between longitudinal axes O₁ and O₂ of channels 7 and 8, has a profile of double tee. Part of bottom and upper part of tray arranged between longitudinal axial planes of channels form shelves of double tee, and longitudinal partition wall - wall of double tee. At least along one side of the axial longitudinal plane Y of the partition above one of channels 7 or 8 in the upper part of tray 1 there are through water passages. Through cassettes can be arranged on both sides of longitudinal axial plane Y of the partition above two longitudinal channels 7 and 8. Versions of the tray are proposed.

EFFECT: higher strength properties of the tray for longitudinal loads, as well as reduced weight of the tray due to reduced thickness of the upper part and side walls.
