PURPOSE: A reinforcing system for the soft ground by a double vertical drainage structure is provided to reinforce the soft ground rapidly by discharging pore water of the soft ground. CONSTITUTION: The reinforcing system for the soft ground by a double vertical drainage structure comprises: a sand column(31) formed in the soft ground(20) to absorb pore water from the soft ground and to discharge to the surface of the earth; and a porous tube(14) installed along the inside of the sand column(31), provided with many passages for letting pore water flow in and an inner space for discharging the pore water to the surface of the earth, so that the soft ground is reinforced by discharging pore water double through the sand column(31) and the porous tube(14).
