Problems solved by technology

However, most of them are in the experimental stage. Considering the economy and applicability, they have not been widely used. During the normal operation of the existing subway lines, the traditional monitoring technology cannot be implemented in the high-density traffic section, and cannot meet the needs of a large amount of data. Requirements for collection, analysis and timely and accurate feedback

Embodiment Construction

[0027] Below in conjunction with accompanying drawing and embodiment, the present invention will be further described:

[0028] refer to Figure 1-5 : An optical fiber static level, including a sensor fixing plate 7, the top of the sensor fixing plate 7 is fixed with a casing 1, the position of the casing 1 can be fixed by the sensor fixing plate 7, and the interior of the casing 1 is close to the top edge The ring block is fixed by the inner hexagon fixing screw 2, and the temperature compensation grating 4 is fixed inside the ring block. The position of the ring block can be fixed by the inner hexagon fixing screw 2. The position of the complementary grating 4 is installed and fixed. The temperature-compensated grating 4 can eliminate the influence of temperature on the sensitivity and accuracy of the sedimentation sensor, and improve the reliability of the sensor. The fiber grating and the steel sheet connector 5 are rotatably connected, and the steel wire rope 11 is fixed...

Abstract

The invention provides a method for optical fiber static level monitoring subway tunnel settlement, and relates to the technical field of subway tunnel settlement monitoring. The optical fiber static level includes a sensor fixing plate, a casing is fixed on the top of the sensor fixing plate, and a ring block is fixed inside the casing near the top edge by a hexagonal inner stabilizing screw, and the ring block is A temperature-compensated grating is fixed inside. The optical fiber static level monitoring method for the settlement of subway tunnels. In addition to the characteristics of the general static level, the optical fiber static level is combined with a fiber grating and a steel sheet connector to form a clamping device, which will make the static level use for a long time. It is stable and can be used for more than five years. At the same time, in use, the use of optical fiber static level to monitor the settlement of subway tunnels can effectively improve the use space of subway tunnel settlement monitoring, and improve economy and applicability.

Description

technical field [0001] The invention relates to the technical field of settlement monitoring of subway tunnels, in particular to a method for optical fiber static level monitoring of subway tunnel settlement. Background technique [0002] Subway tunnel settlement monitoring is an important branch of underground space health monitoring, and it is also an extensive and in-depth research topic by domestic and foreign experts in recent years. The subway tunnel is located underground, the structure is complex, the monitoring is difficult, and the amount of monitoring works is large. The traditional monitoring methods are difficult to meet the safety monitoring of the subway tunnel. Therefore, it is imperative to develop an effective new monitoring method. Many domestic and foreign experts are also working on an effective monitoring scheme to ensure the normal operation of subway tunnels and to guide the construction of subway tunnels. [0003] At present, the health monitoring o...
