Problems solved by technology
[0002] Traditional manual monitoring cannot realize the settlement monitoring during the subway operation period, and the intensive reading is low, the cost of human resources is high, and the measurement interval is long, so it is difficult to realize the extraction and analysis of the continuous settlement law of the tunnel; the measurement points of the static level are generally arranged discretely In order to reduce costs, it is difficult to measure continuous settlement; the robot total station has high rental or purchase costs, and has high requirements for power supply. It is necessary to configure a special power supply box nearby or install it near the existing distribution box. Make the deployment section restricted

Embodiment Construction
[0051] like figure 1 As shown in the figure, the present invention proposes a tunnel longitudinal deformation monitoring system based on a flexible displacement sensing device, which includes several series-connected measurement units 1 and a wireless transmission gateway 2, and the measurement unit 1 includes a long thin hard round rod 11 and one end of the rubber soft joint 12 wrapped with wiring, and the other end is a slot 13. Insert the rubber soft joint 12 of the previous measurement unit into the slot 13 of the latter measurement unit to complete the series connection. The hard round rod 11 has a built-in inclination sensor 14, which can sense the spatial attitude change of the measuring unit 1, and output the angle measurement value between the three-axis coordinate system built in the angle sensor 14 itself and the horizontal plane, so that the angle measured in the same direction as the long thin hard round rod 11 is output. The measured value of the angle between th...

The invention discloses a tunnel longitudinal deformation monitoring system based on a flexible sensing device, an installation method and a settlement algorithm. The tunnel longitudinal deformation monitoring system comprises a plurality of sections of measuring units which are connected in series and a wireless transmission gateway, and the installation method comprises the steps of punching holes in a tunnel lining or installing a support of the deformation monitoring system on a tunnel lining pre-buried groove and an installation process. The settlement algorithm comprises a single-section measurement unit settlement monitoring algorithm based on a built-in tilt angle sensor of the flexible sensing device and an algorithm for monitoring settlement in a certain section by a plurality of sections of measurement units connected in series. The monitoring equipment and the algorithm systematically provide a wireless, real-time and sectionally continuous monitoring means for monitoring the longitudinal deformation of the tunnel, and provide a powerful monitoring guarantee for the construction and operation of the tunnel.
Description
technical field [0001] The invention relates to the technical field of tunnel engineering monitoring, in particular to a tunnel longitudinal settlement monitoring system based on a flexible displacement sensing device, an installation method and a settlement calculation method. Background technique [0002] The traditional manual monitoring cannot realize the settlement monitoring during the subway operation period, and the intensive reading is low, the cost of human resources is high, and the measurement interval is long, so it is difficult to extract and analyze the continuous settlement law of the tunnel; the static level measuring points are generally discretely arranged In order to reduce costs, it is difficult to measure continuous settlement; the robotic total station has high rental or purchase costs, and has high requirements for power supply. It needs to be equipped with a special power supply box nearby or installed near the existing power distribution box. The la...
