Features of the drainage device for backfilling the sinuses of retaining walls, depending on the type of flooding and the structure design
Incoming article date: 27.12.2025The location of large logistics centers in mountainous terrain areas requires, as a rule, the installation of protective retaining walls. Construction conditions are often complicated by anthropogenic changes in the terrain in the form of embankments, recesses, technological sites and driveways, as well as communication corridors. In these conditions, in the presence of flooding and seismicity of the site, it is necessary to install wall drainage and surface drainage from the structures of the retaining walls. The paper presents solutions for the drainage of backfilling sinuses of retaining protective walls, depending on the engineering-geological, engineering-hydrogeological conditions of the territories and the structure of the structure. In particular, for walls with a height of more than 3.6 m and the possibility of draining drainage water to the front of the structure, it is recommended to install a wall drainage with geotextile on a layer of greasy clay at the level of the outdoor blind area and reverse drainage filling of the GPS. For walls up to 3.6 m high and prohibiting drainage to the neighboring territory, the most acceptable option would be a wall-mounted drainage with water drainage along the drainage pipe to the edge of the structure.
