PROBLEM TO BE SOLVED: To provide an automatic slurry pressure control method and controller capable of realizing smooth drive without causing troubles in drive while performing slurry pressure control. SOLUTION: This is an automatic slurry pressure control method for an excavation and drive machine based on a slurry shield method and is able to select the a parameter out of pressured feed speed, amount of filling, and drive speed out of automatic or manual transfer by the operator's judgment operating the excavation drive machine is controlling the slurry pressure and controlling the earth covering (depth of pipe line embedded), soil (sandy soil, cohesive soil, sand gravel and property of sand), N value (value expressing the hardness of soil) under the condition where the changes in these values occur and also automatic or manual switching out of feed speed, amount of filling or drive speed. |
