The invention proposes a series pressure sensor applied to the shield tail sealing system of a shield machine, including a base, the upper part of the base is connected with a cover plate, and a mounting groove is arranged in the base, and a ceramic pressure sensor is arranged in the mounting groove, and a ceramic pressure sensor is arranged in the mounting groove. The pressure sensor is matched with the cover plate, a positioning groove is arranged on one side of the installation groove, a control circuit board is arranged in the positioning groove, and a detection component is arranged at the bottom of the base, and both the ceramic pressure sensor and the detection component are connected with the control circuit board; The circuit board is respectively connected with the power circuit and the communication circuit, and both the communication circuit and the power circuit are connected in series with the communication bus, and the communication bus is connected with the upper computer. In the present invention, the overall structure is compact and compact by integrating the sensors together, and the sensors are connected in series through a bus, which is convenient for installation, and at the same time avoids opening a large area on the surface of the shield tail, and the structure of the shield tail is changed little, which is conducive to popularization .
Description
technical field [0001] The invention relates to the technical field of monitoring the shield tail sealing system of a shield machine, in particular to a series pressure sensor applied to the shield tail sealing system of a shield machine. Background technique [0002] The tunnel forming technology of the shield method is a modern forming technology that uses a large-scale tunnel boring machine that integrates various engineering operations such as excavation, support, advancement, and lining to complete tunnel excavation. There will be a certain gap (generally within 200mm) between the shield tail support structure of the shield machine and the tunnel lining structure, and a shield tail sealing device is provided at the end of the shield tail to prevent muddy water and grouting materials from entering between the shield tail and the lining. The gap flows into the shield body. At present, the commonly used shield tail sealing device is to apply shield tail sealing grease to ...
