Kind Code:
A1
Abstract:
The present invention relates to a channel (1) for use in the field of basic sanitary services, more specifically to a pre-moulded channel for rainwater draining systems, developed to satisfy the surface drainage needs of hydrographic basins and urban areas of growing density. The disclosed channel (1) does not require a stabilised ground, can operate at the surface of roads, allowing traffic to circulate and the road section used to be paved, can use modules of variable lengths, and can even serve, when already in use, as a street surface. The channel (1) comprises four basic pre-moulded modular elements made of reinforced concrete or pre-stressed concrete, i.e.: guide cradle (2), bottom (3), walls (4) and (5) and cover (6), of variable dimensions depending on the projected collecting system.
