FIELD: mining.
SUBSTANCE: invention relates to the mining and construction, particularly, to the system for excavating ground from under buried pipe laid close to the ground surface. The invented system contains the vehicle placed on the ground and provided with the hydraulic supply, and the equipment for ground excavation. The equipment for ground excavation has the catching mechanism, earth-moving mechanism for ground excavation from under the pipe and the propellant device to move the equipment for ground excavation. The equipment is activated by hydraulic supply placed at the vehicle. The equipment is provided with the remote control device installed at the vehicle.
EFFECT: ground excavation from under the buried pipe in preparation the pipeline for repair without marring the pipe skin is available.
