Embodiment 1

[0040] like Figure 1~7 A real-time monitoring device for tunnel deformation, comprising a plurality of level gauges 2 arranged at the top of the tunnel 7 for measuring the settlement of the vault of the tunnel 7;

[0041] It also includes a laser range finder 3 arranged on the side wall of the tunnel 7 for monitoring the convergence of the tunnel 7;

[0042] The level 2 and the laser range finder 3 are electrically connected to the data acquisition device 4 , and the data acquisition device 4 is electrically connected to the data base station 5 . Based on this structure, the level instrument 2 and the laser range finder 3 are used to jointly monitor the deformation of the tunnel, which improves the success rate of monitoring and reduces the interference of construction personnel and equipment on the monitoring device.

[0043] The preferred solution is as figure 1 Among them, the data base station 5 is electrically connected to the tunnel monitoring platform 6 . With this ...

Embodiment 2

[0055] On the basis of embodiment 1, a kind of method that adopts above-mentioned tunnel deformation real-time monitoring device comprises the following steps:

[0056] S1, select the position of the deformation measuring point of the tunnel 7;

[0057] S2. Install level 2, laser range finder 3, data acquisition device 4 and data base station 5; set the number of laser beam reflections in laser range finder 3 according to the working conditions, usually it should be set slightly smaller than the limit range to ensure reliability sex.

[0058] There are at least two level gauges in a group, which are communicated through the connecting pipe 23, and liquid is arranged in the level gauge 2; the level gauge 2 in a group should be arranged roughly in the same elevation. For example, the elevation difference does not exceed 1 / 2 of the range.

[0059] The height data of one group of leveling instruments 2 is differenced, and the data is sent to the data acquisition device 4; multip...

Abstract

The invention provides a tunnel deformation real-time monitoring device and method. The tunnel deformation real-time monitoring device comprises a plurality of spirit levels and a laser distance measuring instrument, wherein the spirit levels are arranged at the top part of a tunnel and are used for measuring the vault crown settlement of the tunnel; the laser distance measuring instrument is arranged at the side wall of the tunnel, and is used for monitoring the surrounding convergence of the tunnel; the spirit levels and the laser distance measuring instrument are electrically connected witha data collection device, and the data collection device is electrically connected with a data base station. In the use process, the method comprises the following steps of selecting the deformationmeasuring points of the tunnel, and arranging the spirit levels, the laser distance measuring instrument, the data collection device and the data base station, so as to monitor the vault crown settlement and the surrounding convergence of the tunnel. The tunnel deformation real-time monitoring device and method have the advantages that the vault crown settlement and the surrounding convergence ofthe tunnel are respectively measured by the spirit levels and the laser distance measuring instrument, so as to more reliably monitor the deformation of the tunnel in real time; by arranging the monitoring type of data collection device and data base station, the unmanned duty type monitoring can be realized.

Description

technical field [0001] The invention relates to the field of tunnel deformation monitoring, in particular to a tunnel deformation real-time monitoring device and method. Background technique [0002] With the rapid development of the transportation industry, tunnel projects are increasing day by day. Tunnel engineering is an underground project with complex construction conditions and high risks. Sudden accidents often lead to personal casualties, delays in the construction period, and huge economic losses. important means of safety. In the existing technology, the manual method of total station is used for monitoring, and it is necessary for monitoring personnel to enter the tunnel regularly to obtain changes in the settlement of the vault and the convergence of the arch waist. There are problems such as limited monitoring frequency, untimely feedback of monitoring information, and artificial modification of monitoring data. . A safety hazard has been laid. [0003] Chi...
