MODULAR NEEDLE FILTER ASSEMBLY OF THE DEWATERING UNIT Russian patent published in 2023 - IPC E02D19/10 B33Y80/00 

FIELD: construction.

SUBSTANCE: invention relates to dewatering during the construction of foundations and structures, in particular to needle filter units and can be used to extract water in hard-to-reach areas without local water sources. The modular needle filter assembly of the dewatering unit made using additive manufacturing technologies includes a cone-shaped tip, a base, and a transition element connected to each other by a threaded connection. The base of the needle filter assembly consists of external and internal perforated cylinders having a common partition in the lower part, separating the modules of the needle filter assembly into separate independent containers, and the filter element is located in the cavity between the perforated cylinders.

EFFECT: simplification of the needle filter design with the possibility of using the potential of the aquifer in full.
