Abstract

PURPOSE: To dispense with expensive conduit installation and ensure labor-saving pipe-laying operations in connection with equipment for constructing air conduit which is used for-horticulture (plant raising by hothonse, vinyl house, etc.) to accumulate and adjust underground temperature.
CONSTITUTION: A port 7 for injecting agents for solidfiying soil around the digging groove is provided for the rear end of the underground mover 1 of proper size which is equipped with digging section 1' at the tip. Connecting pipe 6 is connected to the port 7 through the solidifier tank 4 to manipulate by dragging W the underground mover 1 from the surface.
