description The invention discloses a foundation heating device and a construction method for foundation heating combined vacuum prepressing of a soft soil foundation by applying such device. Vertical plastic draining plates are arranged in a foundation, plate heads of the vertical plastic draining plates are connected to transversely arranged filter pipes, outlet ends of all filter pipes are communicated with an inlet of a pressure guiding flow separating device, heating devices are further arranged in the foundation, a sand cushion layer is paved on the foundation, the filter pipes are buried in the sand cushion layer, a thermal insulation layer is paved on the sand cushion layer, and a sealing film is paved on the thermal insulation layer to form a closed vacuum prepressing system. During work, the pressure guiding flow separating device is firstly opened to perform foundation reinforcing treatment by a general vacuum prepressing method; when general drainage consolidation is performed to the later stage, a temperatur
