description The invention discloses a deep soft foundation treatment construction technology. The deep soft foundation treatment construction technology comprises the following steps that construction preparationand field flattening are conducted; a sand cushion layer is laid, and a vertical water drainage device is punched and arranged; vacuum pipe net arrangement is conducted, and a horizontal pipe and a vertical pipe are included; sealing film pavement is conducted; a sealing ditch is excavated along the periphery outer edge of a pre-pressing area; a vacuum pump is started; after completion, a grouting pump is arranged and connected to the vertical pipe, and grouting work is conducted after grouting liquid is prepared; during grouting work, the vertical pipe is upwards pulled out many times, and grouting work continues after upward lifting each time till deep soft foundation treatment is finished. The vertical pipe has good breathability, the outer surface of the vertical pipe is wrapped by aninverse filtering materia
