Abstract

The invention discloses a tunnel construction surrounding rock loosing circle deformation automatic monitoring early-warning device and method. The device comprises sensing systems and collection transmission systems fixedly connected to a tunnel lining surface; multiple detection fracture surfaces are arranged in a tunnel, and multiple sensing systems are arranged on each detection fracture surface; at least one collection transmission system connected with each sensing system is arranged between multiple adjacent detection fracture surfaces; the sensing systems are used for monitoring tunnel construction surrounding rock loosing circle deformation in real time and the monitoring data is sent to the collection transmission systems, and the data interaction is performed between the collection transmission systems and a remote terminal, and the early-warning in different levels is performed. The device disclosed by the invention is simple in structure, convenient to mount and use, low in cost, and capable of eliminating tunnel construction interference, high in monitoring precision, good in performance, and real and reliable in measurement; the automatic data collection and automatic alarming are performed, and the information is automatically pushed to a background, thereby facilitating a construction department to formulate a solution in time according to the corresponding monitoring information, the tunnel construction security and the construction efficiency are greatly improved.

Description

technical field [0001] The invention relates to an automatic monitoring and early warning device and method for deformation of surrounding rock loose circles during tunnel construction, and belongs to the technical field of tunnel manufacturing and monitoring equipment. Background technique [0002] During the tunnel construction process, the measurement of the deformation of the surrounding rock loose circle is a must-test item, and the accuracy of the measuring instrument is required to be no less than 0.1mm. Due to the limitation of accuracy, the measurement of the deformation of the surrounding rock loose circle during the tunnel construction process is divided into two items: the peripheral displacement and the vault sinking, which are measured by the convergence meter and the level instrument respectively; if necessary, the internal displacement of the surrounding rock is monitored by a multi-point displacement meter . In addition, some projects have also got rid of t...
