PROBLEM TO BE SOLVED: To provide a grouting method support processing device allowing a solidifying material to be uniformly grouted into an improvement object ground area regardless of the building direction of grouting outer pipes 3.;SOLUTION: The device carries out support processing for a grouting method for improving the ground by forming a plurality of grouting holes in the ground Z, installing the grouting outer pipes 3 having a plurality of grouting ports 5, in the holes, and then grouting the solidifying material into the ground from the respective grouting ports 5 of the grouting outer pipes 3. The device includes a device for computing actual position information of each grouting port 5 based on position information of each grouting outer pipe 3 based on design, and measured hole bending information of the grouting outer pipes 3, selecting the grouting port 5 in charge located in the shortest distance regarding injection mesh M based on the actual position information and position information of each injection mesh M, computing the total soil quantity of the injection mesh M of which each charge grouting port 5 is in charge based on the selection, and preparing grouting quantity information of the solidifying material grouted from each charge grouting port 5 according the computed value.;COPYRIGHT: (C)2011,JPO&INPIT
