PROBLEM TO BE SOLVED: To efficiently fill a plurality of embedded pipes which are embedded under the ground in a span between manholes, and to sufficiently fill an embedded pipe which has one end thereof exposed from the ground. SOLUTION: There is provided an embedded pipe filling method. According to the method, the three embedded pipes 2a, 2b, 2c are arranged in the manhole 1a, and a filler is injected from an end of one of the embedded pipes 2a. Then in the manhole 1b where the other ends of the respective embedded pipes 2a, 2b, 2c are present, the other end of the embedded pipe 2a into which the filler is injected is connected to the other ends of the other two embedded pipes 2b, 2c via a hose 15. By virtue of provision of the hose 15, the three embedded pipes 2a, 2b, 2c connected via the hose 15 can be collectively and efficiently filled, and further a barricade need not be set on the periphery of the manhole 1b in which the other ends of the embedded pipes are present.
