Problems solved by technology

[0003] The general subsidence monitoring is to use a total station with a prism for fixed-point monitoring, but the daily operation of the subway cannot be interrupted, so it is difficult for the staff to frequently enter the tunnel for monitoring, and it is impossible to obtain tunnel subsidence information in time. Security risks

Embodiment Construction

[0065] The following is attached Figure 1-7 The application is described in further detail.

[0066] In one embodiment, as Figure 7 As shown, the application discloses a method for monitoring the settlement of a buried tunnel, which specifically includes the following steps:

[0067] S10: Obtain the monitoring position and install the total station based on the length and direction of the tunnel.

[0068] In this embodiment, based on the length and direction of the tunnel, a total station is installed in each tunnel and the total station is located in the middle of the tunnel. The total station includes a CMDA communication module for receiving and sending wireless signals.

[0069] Specifically, based on the length and direction of the tunnel, a bracket is used to fix a total station in the middle of each tunnel, and the installation position of the total station is obtained as the monitoring position.

[0070] S20: Obtain several reference point positions and install se...

Abstract

The invention relates to a monitoring method and system for subsurface tunnel settlement, and the method comprises the steps: obtaining a monitoring position based on the length and direction of a tunnel, and installing a total station; based on the monitoring position, obtaining a plurality of reference point positions and installing a plurality of prisms; when a monitoring instruction sent by the monitoring terminal is received, sending a starting instruction to the total station; when the total station receives a starting instruction, test signals are sequentially sent to the prisms at the reference point positions, and a monitoring result is generated; and sending a monitoring result to the monitoring terminal. The tunnel settlement monitoring device has the advantages that the tunnel settlement degree can be monitored conveniently, and workers can obtain tunnel settlement information in time.

Description

technical field [0001] The present application relates to the technical field of tunnel monitoring, in particular to a monitoring method and monitoring system for submerged tunnel settlement. Background technique [0002] With the development of urban rail transit and the continuous increase of subway lines, the pattern of urban underground engineering has become more and more complex. Therefore, periodic monitoring of the settlement information of subway tunnels is the key to ensuring the normal operation of the subway during the construction process. work one. [0003] The general subsidence monitoring is to use a total station with a prism for fixed-point monitoring, but the daily operation of the subway cannot be interrupted, so it is difficult for the staff to frequently enter the tunnel for monitoring, and it is impossible to obtain tunnel subsidence information in time. Security risks. Contents of the invention [0004] In order to facilitate the monitoring of the...
