「これまでは事前に遠隔操作システム専用PLC制御盤や比例電磁弁等を吹付け機に搭載した専用機を使用するため、高額な費用を要し汎用性が低く…これらの課題を解決し新たに開発した技術を取り入れた。無線通信やバッテリー駆動を主体としたシステム構成で、汎用機械に容易に搭載できる。」
従来の専用機方式を、無線通信・バッテリー駆動により汎用機械へ搭載できるシステムへ改良し、現場適用性と普及性を高める方向へ進展した。 - FY2017First statedAnnual report
「Three cameras are installed on the remote shotcrete machine, and shotcreting is performed while viewing monitors in a control room located away from the tunnel face. Trial construction was conducted at an actual tunnel site to confirm feasibility. The Group plans to actively deploy the remote shotcrete system at actual sites.」
The Group developed a system that keeps workers away from the hazardous tunnel face and enables shotcreting from a control room using 3 cameras, and confirmed its feasibility through trial construction at a tunnel site.
