FIELD: construction.
SUBSTANCE: invention relates to excavators and is intended for digging trenches. Trenching machine contains one or more rocket engines directed to a place of desired ground excavation. Structural design is made in three versions. In the first version the trenching machine has a fan directed to the dug trench. In the second version the trenching machine has a transversely located ahead and/or behind reflector in the form of letter V or of "gull wing” type. In the third version the trenching machine is made as a crossbar temporarily transversally attached to two tanks to support the rocket engines, tanks with rocket fuel, and an engine with the fan.
