METHOD FOR FORMATION OF TWO-SPACE PIPE IN DRAIN OF ELASTIC TAPE Russian patent published in 2010 - IPC E02B11/00 

FIELD: agriculture.

SUBSTANCE: method for formation of drainage and irrigation system includes transformation of elastic tape directly in drain into shape of pipe, which is formed into two longitudinal equivalent cavities, by bending of tape edges inside drain cavity, which support upper arch of shaped two-space pipe, in case when two-space pipe operates as drain. If two-space pipe is turned by 180 degrees, then it operates as subsoil sprinkler. At the same time tape edges are leaned against lower arch of pipe in drain. Between edges bent inside tape, strip of filtering material is arranged along joint length, which also reinforces support of pipe arch. Elastic tape that forms two-space pipe may be withdrawn from drain for prophylactics when there is a technological necessity to involve field into crop rotation.

EFFECT: invention makes it possible to increase assembly manufacturability, to reinforce arch supports, to eliminate penetration of soil particles into pipe cavities and to expand application range.
