Device for reinforced (rfd) thermal vacuum pre-compaction that has with fever type drain bar of ultra-soft soil

The utility model discloses a device for reinforced (rfd) thermal vacuum pre-compaction that has with fever type drain bar of ultra-soft soil. Including a plurality of U-shaped hot-water lines of multirow, all be equipped with the lattice-shaped core of cladding filter membrane between every U-shaped hot-water line, the hot water bucket is through the water pump, the inlet tube, a plurality of U-shaped hot-water lines and return water pipe connector hot water bucket, the vacuum pump is connected with the lattice-shaped core of cladding filter membrane respectively through the drain pipe, and the polyvinyl chloride film is laid on a plurality of U-shaped hot-water line upper portions, and both ends form seals up the ditch, seals up and is filled with earth in the ditch the utility model discloses an outward appearance and ordinary drain bar are similar, need not to change the drain bar and beat and establish machinery, can adopt solar energy heating cycle water, energy saving, reduce cost, thermal vacuum pre-compaction NULL heating and vacuum pre-compaction advantage between them, not only can accelerate the concrete speed of ultra-soft soil, still can improve the final settlement of ultra-soft soil, this method is similar with conventional vacuum pre-compaction method, has only increased the connection of hot-water line and has added nice and warm pumping installations, and easily the engineering is implemented and is promoted
