PROBLEM TO BE SOLVED: To provide a long distance pressure feed injection method of a cement system filler which is used for performing long distance pressure feeding and injection of a filler which can be injected and executed without choking a pipe even when it is transferred long distance by using a conventional material. SOLUTION: Liquid A is made by adding and arranging a first thickener and a second thickener to cement and water, and liquid B is made by adding and arranging the first thickener and the second thickener to an inorganic system filler and water. In the long distance pressure feed injection method of the cement system filler, which is executed after mixing liquid A with liquid B and thickening them, liquid A and liquid B are transferred long distance by separate pipes 154, 174. Then they are mixed with each other through the means of an agitation device immediately before an execution part, and are injected and executed. COPYRIGHT: (C)2009,JPO&INPIT
