The invention discloses a round tunnel flow-passing surface inverted arch special protection device and a manufacturing method. The special protection device mainly comprises geotechnical cloth, a bamboo springboard, graded broken stone, a water stable layer and bricked drainage ditches arranged on two sides, the geotechnical cloth is arranged on a poured round tunnel flow-passing surface inverted arch, the bamboo springboard is paved above the geotechnical cloth and covers the same, the graded broken stone is paved on the bamboo springboard and rolled compactly, the water stable layer is paved on the graded broken stone and rolled flatly and smoothly, and the bricked drainage ditches are arranged on two sides of the water stable layer. The graded broken stone is composed of 15% of medium stone, 45% of small stone and 40% of sand, and the water stable layer is formed by mixing sand-stone aggregate, adding cement accounting for 4% of weight of the sand-stone aggregate and mixing, wherein the sand-stone aggregate is composed of 55% of small stone and 45% of sand. By the special protection device and the manufacturing method, civilized construction environment is improved, the problems of low construction efficiency, high cleaning labor intensity of personnel, time and labor consumption and protruding potential safety hazards are solved, labor intensity and potential safety hazards of manpower are lowered, civilized construction image is improved, construction progress is accelerated, and construction cost is saved.
