PURPOSE: A management system for the soft ground improvement is provided to improve the accuracy and convenience on construction. CONSTITUTION: The management system for the soft ground improvement contains a tractor grade sensor(21) sensing a grade of a tractor, a leader grade sensor(22) sensing a grade against a leader of the tractor, a transmitter(23) sensing the indentation depth of a mandrel attached to the leader, a sweep back length sensor(24) sensing the sweep back length of a drain board which goes back by drawing the mandrel after indenting together with the mandrel, a current sensor(25) sensing the current flowing along a vibro-hammer used for indenting the mandrel, a drawing motor(26) drawing the defective drain board, a tension sensor(27) sensing the tensile force of the drain board if the drawing motor(26) pulls out the indented drain board, an approach sensor(28) sensing the zero point of the mandrel, and a management system(300) analyzing and displaying the information transmitted from various sensors. |
