The invention discloses a construction method for installing a nodular cast iron pipe, and relates to the technical field of municipal water supply and the like. The position and depth of a groove of the nodular cast iron pipe are determined through groove foundation survey, guidance is provided for follow-up construction work, excavation is conducted according to geotechnical engineering survey results, slope making is conducted according to construction acceptance specification requirements, and the nodular cast iron pipe is installed. After the nodular cast iron pipeline is installed at a surveying and determining position, the nodular cast iron pipeline is connected through a rubber ring connector so as to ensure connection firmness and sealing performance of the pipeline, a 360-DEG C 30-degree full-wrapping concrete foundation, a sand gravel cushion layer and a 180-degree medium-coarse sand cushion layer foundation are adopted at the position, stable supporting and protection can be provided for the pipe
