摘要
The method involves putting all pipes and lines underneath a roadway (12). The new lines are arranged one above the other underneath a lateral sidewalk with one or two sewer pipes covering them and a gas pipe (44) further above and completely above the telecommunications cables. All lines are accessed by several inspection pits (34), which are accessible underneath the sidewalk (14) arranged in distances to each other, and having a cover (40). The distances are in accordance with the need of branches needed to the individual pipes and lines. The road pavement is adapted to an easy downward gradient to the side of the sidewalk, under that the shifted pipes are located.
