Construction management method of earth pressure shield method, construction management equipment and earth pressure shield excavator

摘要

PROBLEM TO BE SOLVED: To provide a construction management method of soil pressure type shield construction capable of aiming a rationalization of the injection method of a mud-added material toward excavated soil in a chamber, a construction management device and a soil pressure type shield drilling machine.SOLUTION: The construction management method of soil pressure type shield construction includes: an estimation step S1 of estimating a plastic flow state of excavated soil in a chamber for each combination of parameters by performing a parameter study by particle method analysis of setting an injection condition of a mud-added material as a parameter before drilling beforehand; an evaluation step S2 of evaluating the plastic flow state of excavated soil in the chamber in drilling; and an injection step S3 of selecting a predetermined injection condition suitable for the plastic flow state evaluated by the evaluation step S2 from estimated results estimated by the estimation step S1 and injecting the mud-added material into excavated soil in the chamber on the selected injection condition.SELECTED DRAWING: Figure 1
