In the buried pipe propulsion device for propulsion, a hydraulic gradient detection unit detects the hydraulic pressure between the hydraulic pump and the hydraulic jack at predetermined intervals and calculates the hydraulic gradient of this hydraulic pressure, and the hydraulic gradient detecting unit detects the hydraulic pressure between the hydraulic pump and the hydraulic jack, and calculates the hydraulic gradient of this hydraulic pressure, and compares the hydraulic gradient with the hydraulic gradient. a setting unit configured to set a standard setting value, and a setting unit that determines that the lead pipe has come into contact with an existing underground object when the hydraulic gradient reaches the standard setting value, and stops the operation of the hydraulic pump. A buried pipe propulsion device comprising a pump control means. (2) The buried pipe propulsion device according to claim 1, wherein the period is variable. (3) The buried pipe propulsion device according to claim 1, wherein the reference setting value of the setting section is variable depending on soil quality, propulsion pipe diameter, etc.
