EXCAVATION BOTTOM FACE MONITORING SYSTEM
To provide an excavation bottom face monitoring system which obtains deformation of an excavation bottom face and detects abnormality from the deformation by combining change information of a distance from a caisson bottom slab to an excavation bottom face and progress information of caisson settlement.SOLUTION: An excavation bottom face monitoring system comprises: a settlement amount obtaining portion 11 obtaining caisson settlement amount from measurement start time to measurement finish time; a distance measurement portion 12 installed on a bottom slab of the caisson and measuring a distance to an excavation bottom face; an excavation bottom face obtaining portion 13 obtaining deformation information of the excavation bottom face by correcting change amount of the distance from the measurement start time to the measurement finish time using the settlement amount; a determination portion 14 determining whether abnormality is generated on the excavation bottom face based on the deformation information; and an alarm generation portion 15 notifying the abnormality when the determination portion 14 detects generation of the abnormality.SELECTED DRAWING: Figure 1
【課題】ケーソン底版から掘削底面までの距離の変化情報と、ケーソン沈下の経過情報とを併用することにより、掘削底面の変形を取得し、当該変形から異常を検知する、掘削底面監視システムを提供する。【解決手段】測定開始時刻から測定終了時刻までのケーソンの沈下量を取得する沈下量取得部１１と、ケーソンの底版に設置され、掘削底面までの距離を測定する測距部１２と、測定開始時刻から測定終了時刻までの前記距離の変化量を、沈下量で補正することにより、掘削底面の変形情報を取得する掘削底面取得部１３と、変形情報に基づいて掘削底面に異常が発生しているか否かを判定する判定部１４と、判定部１４が異常発生を検知したときに異常を報知する警報発生部１５とを備える。【選択図】図１
