The system consists of prefabricated parts of two types 1 and 2, it being possible to form the gutter from either one of said types or by means of a combination of both, depending on the features desired. The principal novelty consists in the fact that each side of the gutter is formed by means of parts 1 and/or 2 which are totally independent of those of the other side, allowing great constructional flexibility, to produce pipe (drainage) systems of various shapes and sizes, including variations in and asymmetry of width, angle and volume of the corresponding gutters. This makes it possible perfectly to adapt the system to the requirements of each case, especially open pipe systems in parks, gardens and by thoroughfares, roads, etc. <IMAGE>
