1. A modular element or semi-module (100) for making underground structures for basins designed to manage meteoric waters or underground structures for retaining soil, comprising:
a planar base portion (101); and
a plurality of pillars (10) rising from said base portion (101), said plurality of pillars (10) being connected to said base portion (101) by a larger base (11);
wherein each of said pillars (10) is hollow and each of said pillars (10) comprises a first external wall (14) defining an internal cavity (13),
wherein said first external wall (14) is tubular and defines said internal cavity (13),
wherein, inside said internal cavity (13) in each of said pillars, there is a stiffening tubular internal wall (17) which is spaced from said external wall (14) and has a prismatic shape or a shape corresponding to that of said external wall (14), said stiffening tubular internal wall (17) being connected to said external wall (14) by a smaller pillar base (12) opposite said larger base (11),
wherein said external wall (14) and said internal wall (17) have a same height, and
wherein said internal wall (17) and said external wall (14) are joined together by connecting partitions (18) configured to allow water to flow therethrough.
