Description

本発明は、切羽の状況を工事関係者にメールで報知するシステムと、その報知方法に関する。   The present invention relates to a system for notifying a person concerned with a work face by e-mail and a notification method thereof.

特許文献１において、シールド掘削中のトンネル切羽でのガス濃度を計測して警報を発する提案が公知となっている。
また、特許文献２において、切羽から放射される熱赤外線の検知による温度分布情報と、切羽を反射した近赤外線の検知によるその強度分布情報とから、湧水が生じているエリアを評価特定する提案が公知となっている。 In patent document 1, the proposal which issues a warning by measuring the gas concentration in the tunnel face during shield excavation is known.
