Summary: | PROBLEM TO BE SOLVED: To provide a center formwork device of tunnel lining capable of determining a concrete placement height and a concrete lining placement system using the formwork device that ensure quality of the lining concrete and save labor in lining placement work, utilizing a low-priced non-contact type sensor.SOLUTION: A lining placement system of the present invention includes: a center formwork for a tunnel installed over an inner space side of a tunnel, from an outer peripheral surface of a tunnel lining toward a tunnel central side leaving a prescribed interval; a non-contact type sensor installed at a prescribed location on the center formwork for a tunnel that has been installed, for receiving a detection signal that detects whether concrete has been placed; and control means for specifying a concrete placement location between the outer peripheral surface of the tunnel lining and the center formwork for a tunnel, based on the detection signal received by the non-contact type sensor.SELECTED DRAWING: Figure 1
【課題】本発明は安価な非接触型のセンサを利用し、覆工コンクリートの品質確保と覆工作業の省力化を実現できる、コンクリートの打設高さを判別するトンネル覆工のセントル型枠装置およびこれを利用したコンクリートの覆工打設システムを提供することを目的とする。【解決手段】本発明は、トンネルの覆工外周面からトンネル中心側に向かい所定間隔をおいて、トンネル内空側に亘って設置されるトンネル用セントル型枠と、前記設置されたトンネル用セントル型枠の所定箇所に設置され、コンクリートの有無を検出する検出信号を受信する非接触型センサと、トンネルの覆工外周面と前記トンネル用セントル型枠間に打設されるコンクリートの打設位置を前記非接触型センサが受信した前記検出信号によって特定する制御手段とを有することを特徴とする。【選択図】 図1 |
