DRY WELL Russian patent published in 2017 - IPC E02B11/00 

FIELD: construction.

SUBSTANCE: dry well 1 comprises the cylindrical housing, in the bottom part of which the closed arch-type structure with the vault of the hemispherical shape is placed. The closed structure has the perforation in the form of mesh partitions of the upper part 3 and the lower part 2. Inside the closed structure made in the form of mesh partitions 2 and 3, the drainage element is placed, in the form of a soft elastic material, e.g. rounded rubber 4, the longitudinal edges of which are fixed between the partitions 2 and 3. The closed structure is made of metal mesh or a plastic material of increased strength with perforation. The circular channels in the soft elastic material 4 are placed around the entire perimeter relatively to the vertical symmetry axis symmetrically and at an acute angle to the vertical symmetry plane of the housing and toward the meshed partitions 2 and 3 perforation. The filter unit 8 in the form of a plate made of coarse porous concrete overlaps the body 1 in the upper part and is placed in a recess within the boundaries of the day ground surface base. At the top the mesh partition 3 is closed with the filter material in the form of gravel backfill 10. The outer sidewalls of the housing 1 have the seal 11, namely poroizol or a thickened geotextile material, which adheres to the sidewalls of the well housing 1, is greased with mastic.

EFFECT: invention can be applied to different objects, can operate all year round and increases the operational reliability of the dry well.
