The invention discloses a method for constructing a large bagged graded broken stone inverted filter. Inverted filter construction is carried out according to the requirements for the flatness and thickness of the inverted filter. The method mainly comprises the following steps that workers process a foundation layer, paying-off workers detect the foundation layer and process the foundation layer slope face, color bar cloth is laid by the workers, graded broken stone is laid through an excavator and is leveled primarily through an excavator, the thickness of the graded broken stone is detected, secondary leveling is carried out through the workers, the color bar cloth is turned back and covers the graded broken stone, other three remaining edges of the color bar cloth are sewn, and the edges needing to be sewn face upward, leftward and rightward to form a large woven bag body. The method has the advantages that the machine and the workers can cooperate with one another to level the surface layer of the large bagged graded broken stone inverted filter, the flatness and thickness of the inverted filter can be improved; the thickness of the inverted filter can be detected conveniently, and the height can be adjusted easily; the graded broken stone can be rammed by the excavator at any time; the woven bag can be sewn more easily, conveniently, quickly and firmly.
