| Zusammenfassung: | To provide a tunnel lining construction system capable of improving the work efficiency of a worker in concrete placing.SOLUTION: A tunnel lining construction system according to this invention includes: a placing nozzle for placing concrete from a placing port provided in a gable form of a lining form; a plurality of sensors provided on a surface of a waterproof sheet and the lining form, and used for measuring on the provided positions placing conditions of the placed concrete; a placing nozzle moving guide provided along a circumferential direction of a tunnel; a moving mechanism for moving the placing nozzle in the circumferential direction of the tunnel along the placing nozzle moving guide; and an operation control unit for moving the placing nozzle by the moving mechanism to a height determined according to the placing conditions based on the detection result of the sensors at the position where the sensors are provided between the base end portion and the top end portion of the lining form.SELECTED DRAWING: Figure 1
【課題】コンクリート打設における作業員の作業効率を向上させることができるトンネル覆工施工システムを提供する。【解決手段】覆工型枠の妻型枠に設けられた打込み口からコンクリートを打込む打込みノズルと、防水シート表面と前記覆工型枠に複数設けられ、打込まれるコンクリートの打込み状況を前記設けられた位置において測定するセンサと、トンネルの周方向に沿って設けられる打込みノズル移動ガイドと、打込みノズル移動ガイドに沿って打込みノズルをトンネルの周方向に移動させる移動機構と、覆工型枠の下端部から天端部側のうち、移動機構によって打込みノズルを、センサが設けられた位置における当該センサの検出結果に基づく打込み状況に応じた高さに移動させてコンクリートの打込みをする稼働制御部とを有する。【選択図】図１ |
