FIELD: machine building.
SUBSTANCE: invention relates to municipal infrastructure and particularly describes an assembled bamboo composite communication tunnel. Communication tunnel comprises interconnected components of tunnel, each of which has housing 1 of round cross section, formed by interconnected skin layer 11, structural layer 12 and external protective layer 13, located in radial direction, from inner surface to outer surface of housing 1. Housing 1 is equipped with support element 2 fixed on inner side of housing. Coating layer 11 contains refractory resin and refractory fibers. Structural layer 12 comprises interlayers of bamboo strips wound with the use of water-soluble resin. External protective layer 13 of the housing contains refractory resin.
EFFECT: technical result achieved during implementation of tunnel consists in high strength at low weight, low cost of materials used for its production, low intensity of leaks and high resistance to tectonic processes.
