PURPOSE:To efficiently bury gas pipes, etc., laid in a trench by providing a tank device to discharge soil and sand loaded and a rammer to consolidate the soil and sand discharged to a vehicle running over the trench. CONSTITUTION:A self-running vehicle 1 reciprocally moving over a trench 13 in which gas pipes, etc., are to be buried underground is provided with a tank 3 for loading embedding soil and sand and a rammer for consolidating soil and sand embedded in the trench 13. In the tank 3, soil and sand are loaded and discharged from the outlet 6 of the tank 3 by a screw 7 while being diffused by a soil diffuser blade 8. In this way, soil and sand are discharged from the tank 3 and embedded in the trench 13. Then, the soil and sand are consolidated by the rammer 4 while a gas pipe is buried in the trench. |
