PPROBLEM TO BE SOLVED: To provide a method of constructing an arch culvert capable of easily depositing shotcrete and taking measure against water discharge on the outer periphery thereof without assembling an external scaffold and without impairing landscape. PSOLUTION: In this method of constructing an arch culvert, a plurality of timbering of H-shape in cross section are installed at intervals while the flanges thereof are positioned parallel to the mine shaft of the arch culvert to be constructed. A water conducting sheet and a net covering the surface of the water conducting sheet which faces the inside of the arch culvert to be constructed are arranged so that the water conducting sheet is brought into contact with the inner surfaces of the flanges disposed further on the outer side than the arch culvert to be constructed so as to close the intervals between the timbering. After the shotcrete is sprayed at the portion where the water conducting sheet and the net are overlapped with the flanges, the shotcrete is sprayed on the water conducting sheet through the net.
