一种用于隧道二衬厚度监测的压力感应装置及使用方法
摘要：
本公开提供了一种用于隧道二衬厚度监测的压力感应装置及使用方法。其中，用于隧道二衬厚度监测的压力感应装置，包括：固定部和压力监测部，所述固定部用于固定在洞口内，所述洞口由初次衬砌表面向内开凿而成；所述压力监测部包括气压管，所述气压管的一端与固定部密封连接，另一端与活动部密封连接，所述活动部还与悬浮标相连；所述气压管内设置有压力感应器，所述压力感应器与监测仪相连；所述压力感应器用于实时监测气压管内的压力，隧道二次衬砌的厚度与悬浮标接触且气压管内的压力发生变化时，隧道二次衬砌的厚度达到预设要求。
摘要（英）：

The disclosure provides a pressure sensing device used for tunnel secondary-lining thickness monitoring and a use method. The pressure sensing device used for tunnel secondary-lining thickness monitoring includes a fixing portion and a pressure monitoring portion. The fixing portion is used for fixing in a structural opening. The structural opening is formed by inward digging of a primary-lining surface. The pressure monitoring portion includes an air pressure tube. One end of the air pressure tube is connected with the fixing portion in a sealing manner, and the other end is connected with amoving portion in a sealing manner. The moving portion is also connected with a floating label. A pressure sensor is disposed in the air pressure tube, and is connected with a monitor, and is used formonitoring pressure in the air pressure tube in real time, and the thickness of a secondary lining of a tunnel reaches a preset requirement when the thickness of the secondary lining is in contact with the floating label and the pressure in the air pressure tube has a change.
