Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a monitoring device for deformation of an advanced support structure. Background Art

[0002] When a tunnel passes through soft and broken surrounding rock, excavation disturbance will cause large deformation of the surrounding rock. If the initial support is not implemented in time, the deformation of the surrounding rock may exceed its allowable range, which may cause instability of the heading face and tunnel collapse in severe cases, resulting in significant economic losses. At this time, advance support measures such as the tunnel pipe shed method are required to control the deformation of the surrounding rock, so as to ensure the safety of tunnel construction. Therefore, in the initial support construction process, in order to ensure the support service performance and ensure construction and driving safety, it is very important to monitor the vertical displacement, deformation and deformation pressure of the vertical road surface of the advance support.

[0003] For example, the monitoring device for deformation of the advance support structure with application number CN202320138681.2 and publication date 20230919 includes a monitoring component and a positioning component for installing the monitoring component on the advance support structure; wherein, the monitoring component includes: a support part, the support part has a cavity; a moving part, the moving part can move freely along the axial direction of the cavity; a deformation part, one end of the deformation part is connected to the cavity, and the other end is connected to the moving part; the positioning component includes: a hole body, the hole body passes through the advance support structure and extends into the surrounding rock behind the advance support structure; a positioning part, the positioning part positions the monitoring component between the positioning part and the advance support structure; a rod body, the rod body passes through the positioning part and the monitoring component and is inserted into the hole body. The utility model has a simple structure, is easy to install and use, can monitor the deformation, displacement and force of the advance support structure at the same time, and has strong practicality.

[0004] Most traditional advanced support structure deformation monitoring devices only have detection functions and are unable to adjust the advanced support structure while detecting deformation, so their practicality is low. Therefore, it is urgent to design a monitoring device for the deformation of the advanced support structure to solve the above problems. Utility Model Content
