The invention discloses a device for avoiding buried pipeline sedimentation in a room subsoil backfill region and a construction method. The device comprises a pipe hanger. The upper end of the pipe hanger is connected with anchoring components in a concrete ground beam or a reinforced concrete floor. The center of the bottom of the pipe hanger is connected with a U-shaped clamp. The construction method includes the steps of arranging the pipe hanger in a pipeline trench, arranging a pipeline at the bottom of the pipe hanger and fixing the pipeline through the U-shaped clamp, performing a hydraulic test or a closed water test, performing trench backfill, performing floor construction and the like. The device and the construction method have the beneficial effects that defects existing in the prior art are overcome, the stress carrier of the pipeline is changed fundamentally, the problems of pipeline blocking and breakage and the like caused by foundation settlement are eliminated completely, and the safety an
