AI Technical Summary

Technical Problem

Tunnel support structures are prone to dislocation during settlement, resulting in reduced support capacity, changes in the position of monitoring equipment, and affecting the accuracy of monitoring information.

Method used

Anti-settling parts are used as bottom supports. The locking effect of the locking block is adjusted through the liquid chamber and the liquid guide assembly to maintain the stability of the upper fixed rod. The position of the support frame is adjusted by adjusting the motor and threaded rod to adapt to tunnel deformation.

Benefits of technology

This ensures the stability of the tunnel support structure and the accuracy of the monitoring data, avoids large height differences caused by settlement of the support structure, improves the consistency and accuracy of the monitoring data, and reduces the need for manual adjustments.

Abstract

The invention discloses a supporting structure suitable for tunnel curved surface monitoring and dynamic adjustment, and relates to the technical field of tunnel supporting structures.The supporting structure comprises supporting steel frames and right-angle connecting frames, the right-angle connecting frames are arranged in a left-right symmetry mode, and the supporting steel frames are erected on the right-angle connecting frames through adjusting assemblies; multiple sets of supporting units are arranged between the supporting steel frames, multiple sets of anti-settling parts are arranged at the bottom of the positioning frame, each anti-settling part comprises a lower settling column, the lower end of the lower settling column is embedded into soil, a liquid cavity and a storage cavity are formed in the lower settling column, and a liquid guiding assembly is arranged between the storage cavity and the liquid cavity; liquid in the storage cavity can enter the liquid cavity with the reduced pressure intensity under the action of the liquid guide assembly, and a plurality of sets of locking blocks are arranged in the liquid cavity. According to the device, the anti-sedimentation part serves as a bottom support, the influence of sedimentation on the positions of the supporting steel frame and the monitoring equipment is reduced, and the stability of tunnel supporting and the accuracy of monitoring information are ensured.
