Description
本発明のトンネル切羽面の変位監視装置は、上述した目的を達成するため、以下の特徴点を有している。すなわち、本発明のトンネル切羽面の変位監視装置は、初期形状データ取得手段と、初期形状データ記憶手段と、現形状データ取得手段と、切羽面変位情報作成手段と、切羽面変位情報投影手段とを備えたことを特徴とするものであり、さらに、警報発生手段を備えることが可能である。 In order to achieve the above-mentioned object, the displacement monitoring device for a tunnel face according to the present invention has the following features. That is, the tunnel face displacement monitoring apparatus of the present invention includes an initial shape data acquisition means, an initial shape data storage means, a current shape data acquisition means, a face face displacement information creation means, and a face face displacement information projection means. It is possible to further comprise an alarm generating means.
＜現形状データ取得手段＞
現形状データ取得手段１３は、トンネル掘削工程において形成したトンネル切羽面の現形状データを取得するための手段であり、例えば、ビデオカメラ等の撮像装置及び照明装置等からなる。この現形状データ取得手段１３は、例えば、トンネルの天端等に設置して、トンネル切羽面を撮像対象とする。この際、照度が不足していれば、投光器やＬＥＤライト等の照明装置によりトンネル切羽面に撮影光を照射することが好ましい。現形状データ取得手段１３により取得した現形状データは、切羽面変位情報作成手段１４に送信されて、初期形状データとともに切羽面変位情報の作成に使用する。なお、現形状データ取得手段１３は、初期形状データ取得手段１１と兼用の手段として構成してもよい。
<Current shape data acquisition means>
The current shape data acquisition unit 13 is a unit for acquiring current shape data of the tunnel face formed in the tunnel excavation process, and includes, for example, an imaging device such as a video camera, an illumination device, and the like. This current shape data acquisition means 13 is installed, for example, at the top end of the tunnel, and the tunnel face is taken as an imaging target. At this time, if the illuminance is insufficient, it is preferable to irradiate the tunnel face with photographing light by an illumination device such as a projector or an LED light. The current shape data acquired by the current shape data acquisition means 13 is transmitted to the face surface displacement information creation means 14 and is used to create face surface displacement information together with the initial shape data. The current shape data acquisition unit 13 may be configured as a unit that also serves as the initial shape data acquisition unit 11.
＜切羽面変位情報作成手段＞
切羽面変位情報作成手段１４は、初期形状データ記憶手段１２に記憶したトンネル切羽面の初期形状データと、取得した現形状データとの比較に基づいて、初期形状データと現形状データとの差違を示す切羽面変位情報を作成するための手段であり、例えば、コンピュータ及びその付帯装置と、コンピュータにインストールすることによりハードウェアと協同して動作するアプリケーションプログラムとからなる。
<Cut face displacement information creation means>
The face surface displacement information creation means 14 determines the difference between the initial shape data and the current shape data based on the comparison between the initial shape data of the tunnel face and the acquired current shape data stored in the initial shape data storage means 12. It is a means for creating the face face displacement information shown, and comprises, for example, a computer and its associated devices, and an application program that operates in cooperation with hardware by being installed in the computer.
