The present invention concerns a drainage network, which is characterized by the fact that said drainage network is a network for ground constructions equipped with drainage belts with which a three-dimensional drainage network system for diverting water can be formed in the ground, thereby providing rain water and underground water accumulated in the ground a means to be drained for the purposes of alleviating hydraulic pressure exerted on the ground, increasing ground stability and preventing earth movements from occurring in the construction site.
