FIELD: construction.
SUBSTANCE: method for connection of drainage pipes by toroid coupling made of recycled tyre includes putting coupling on end sections of connected drainage pipes with fixation of coupling sides in erection joints of drainage pipes. Single-sided transverse cut is provided on coupling on top. Putting coupling on drainage pipes is done by elastic opening of coupling ends from cut towards opposite sides at the distance that is not less than diametre of connected drainage pipes, lower parts of erection joints of connected drainage pipes are installed onto central parts of open coupling sides. Afterwards coupling ends are elastically returned into initial condition with full entry and fixation of coupling sides in erection joints of connected drainage pipes.
EFFECT: invention makes it possible to simplify process of drainage pipes connection by means of coupling made of recycled tyre.
