FILLING SITUATION CHECKING APPARATUS OF UNDERGROUND CAVITY AND FILLING SITUATION CHECKING METHOD
PROBLEM TO BE SOLVED: To detect a filling situation of a plurality of places separated in a horizontal direction at a stretch in a filling work to back fill an underground cavity, while keeping each detecting part stabbed on the ground.SOLUTION: A filling situation checking apparatus 1 is provided with a plurality of sensor harnesses 10 to be inserted from the ground surface g into an underground cavity s through a plurality of measurement holes h formed in a longitudinal direction from a plurality of locations on the ground surface g to the underground cavity s. Each sensor harness 10 includes a flexible wire harness 12 extending from the ground surface g to a bottom of the underground cavity s and a plurality of sensors 13 for detecting a presence of filler f, which are connected to the wire harness 12 with a mutual vertical interval selected from the range of 10-50 cm at least in the upper half portion between a lower end of the wire harness 12 and a position in which the length corresponds to the internal height of the underground cavity s or more.SELECTED DRAWING: Figure 1
【課題】地下空洞を埋め戻す充填工事において、水平方向に離間した複数箇所の充填状況を一気に、かつ各検知部を地面に刺したままの状態で検知する。【解決手段】充填状況確認装置１は、地面ｇの複数箇所から地下空洞ｓまで縦方向に形成された複数の計測孔ｈを通して、地面ｇから地下空洞ｓに挿入する複数のセンサーハーネス１０を備えている。各センサーハーネス１０は、地面ｇから地下空洞ｓの底面まで到達する可撓性のワイヤーハーネス１２と、ワイヤーハーネス１２の下端から地下空洞ｓの内法高さ以上に相当する長さまでの間の少なくとも上半部に、１０〜５０ｃｍの範囲から選ばれる相互上下間隔をおいて配置されてワイヤーハーネス１２に結線された、充填材ｆの存在を検知するための複数のセンサー１３とを含む。【選択図】図１
