| description | To provide a shield machine capable of predicting a factor that reduces excavation efficiency.SOLUTION: A shield machine includes a machine body, a cutter head provided at the tip of the machine body, a shield jack for advancing the machine body, and an evaluation device for evaluating excavation. Also the evaluation device calculates an excavation index over time, that is gained by dividing the product of torque (T) of the cutter head, rotational speed (r) of the cutter head, and thrust (F) of the shield jack by speed (V) of the machine body. Further the evaluation device is configured to predict factors that causes drilling index to peak based on the excavation index that is gained, when the excavation index reaches a peak, by dividing any one, or the product of two, that are selected from the group including the torque (T) of the cutter head, the rotational speed (r) of the cutter head, and the thrust (F) of the shield jack by the speed (V) of the machine bod, if the excavation index reaches a peak.SELECTED DRAWING: Figure 2
【課題】掘削効率が低下する要因を予測することができるシールド掘進機を提供する。【解決手段】シールド掘進機は、掘進機本体と、掘進機本体の先端に設けられたカッターヘッドと、掘進機本体を前進させるシールドジャッキと、掘削に関する評価を行う評価装置とを備え、評価装置は、カッターヘッドのトルク（Ｔ）とカッターヘッドの回転数（ｒ）とシールドジャッキの推力（Ｆ）との積を掘進機本体の速度（Ｖ）で除算した掘削指数を経時的に算出し、掘削指数がピークとなる場合に、カッターヘッドのトルク（Ｔ）、カッターヘッドの回転数（ｒ）、およびシールドジャッキの推力（Ｆ）を含む群から選択される何れか１つ又は２つの積を掘進機本体の速度（Ｖ）で除算した評価指数に基づいて掘削指数がピークとなる要因を予測するように構成されている。【選択図】図２ |
