TUBULAR ABSORBING WELL Russian patent published in 2018 - IPC E02B11/00 

FIELD: construction.

SUBSTANCE: invention relates to the construction and hydrotechnical melioration and can be used for drainage of underground parts of buildings and constructions, road sections, banking, excavations. Technical goal of the invention is to increase the service life. Said technical problem is achieved in that the vertical drainage structure includes a drainage pipe 2, the upper end of which is located in the water collector 6, and the lower end is located in the drainage layer 8, the waterproof layer 7 and the gravel package 5 as the sorbent. Gravel package 5 is located in shells 3, enclosing the mouth of drainage pipe 2. Shells 3 are made of a nonwoven filter material 4. Use of a nonwoven filter material as a sheating material ensures a constant outflow of water from the water collector to the water-absorbing layer.

EFFECT: due to the physical and mechanical properties of the non-woven material, mud injection does not take place, the service life of the proposed vertical drainage structure increases.
