FIELD: construction. ^ SUBSTANCE: method for water drawdown of vertical type in basement premises of residential houses, office and industrial buildings and storages includes organisation of a depression zone within the area of a basement premise due to installation of bore pits and a collecting-filtering trench. Inside the perimetre of the basement a collecting-filtering trench (well) is mounted having arbitrary shape, as well as bore pits, arranging the latter in the depression zone, formed by a collecting-filtering trench. Filtering material is laid into bore pits, and when loose, this material forms lower density compared to the main soil of the basement room, or perforated pipes are laid into bore pits as closed with a cover on top, wrapped with a filtering material and sprinkled with a material at the outer side, which does not contain lime. From the collecting-filtering trench at the level of its bottom a water-drain pipe is installed towards a well of a sewage or a storm water system, a check valve is installed into the water-drain pipe, or a device that prevents water ingress from a sewage or storm water system into the drainage system of the basement room. Upon completion of the drainage system assembly, the basement area is filled with a material, which does not contain lime or sand (for instance, with gravel or pebbles). ^ EFFECT: lower ingress of ground waters, reduced wear of engineering utilities and their increased service life, provision of soil skeleton reinforcement. ^ 1 ex |
