Embodiment 1

[0043] This embodiment provides a tunnel deformation detection device 100 whose function is to detect the deformation of the tunnel pipe ring 10 . In actual construction, the tunnel is formed by a plurality of tunnel pipe rings 10 connected in series, and of course the tunnel pipe ring 10 is also composed of a plurality of units.

[0044] Such as figure 1 As shown, the tunnel pipe ring 10 includes a plurality of arc segments 11, and the arc segments 11 are fan-shaped. All arc tube pieces 11 are connected end to end to form a full circle. Of course, in the actual construction process, a certain gap needs to be left between the two circular arc segments 11, and the gap is the connecting seam 12 between two adjacent circular arc segments 11, that is, on the entire tunnel ring 10. A plurality of connecting seams 12 will be formed.

[0045] The tunnel may be deformed within the service life, and the deformation of the tunnel means that the tunnel pipe ring 10 is deformed. The inv...

Embodiment 2

[0088] This embodiment provides a tunnel structure, including a plurality of tunnel rings 10 and the tunnel deformation measuring device in the above embodiment, at least one tunnel ring 10 is equipped with a tunnel deformation measuring device. All tunnel pipe rings 10 are connected in series.

[0089] In this embodiment, a tunnel deformation measuring device is arranged in every three tunnel pipe rings 10, so as to detect the apex of the tunnel and determine the deformation of the entire tunnel.

Abstract

The invention provides a tunnel deformation measurement device and a tunnel structure, and belongs to the technical field of tunnel deformation measurement. The tunnel deformation measurement device is used for measuring deformation quantity of a tunnel pipe ring. The tunnel pipe ring comprises multiple arc segments. A joint seam is formed between the two adjacent arc segments. The tunnel deformation measurement device comprises terminal equipment and multiple angle sensors which are electrically connected with the terminal equipment. One angle sensor is correspondingly arranged at one joint seam, and the angle sensor is used for detecting the relative rotating angle between the two adjacent arc segments to be converted into an electric signal. The terminal equipment is used for receiving the electric signal and processing the electric signal so as to obtain the deformation quantity of the tunnel pipe ring. The detection device can rapidly and efficiently detect the tunnel and can be suitable for the severe environment.

Description

technical field [0001] The invention relates to the technical field of tunnel deformation measurement, in particular to a tunnel deformation measurement device and a tunnel structure. Background technique [0002] With the development of the urban economy, the shield method has gradually become one of the main forms in the fields of transportation and sewage, and this proportion will become larger and larger. During the design service life of the shield tunnel, its healthy service is crucial to the normal operation of the city, and the most important way to evaluate its health is on-site monitoring. [0003] However, most of the existing shield tunnel monitoring is the traditional monitoring method, that is, manual hand-held traditional monitoring instruments are carried out on-site for deformation measurement, which consumes a lot of manpower and financial resources, and the efficiency is low; Monitoring methods are also difficult to implement. Contents of the invention ...
