Technical Field
The utility model belongs to the technical field of tunnel engineering deformation monitoring technique and specifically relates to a novel tunnel engineering deformation monitoring measurement station device.
Background
The tunnel engineering monitoring and measuring is an essential part in the existing tunnel construction design, and is widely applied to the tunnel fields of mines, railways, highways, light rails, water conservancy and the like. In recent years, with continuous development of urban underground engineering and massive construction of high-speed railways and highways, tunnel engineering is increasingly increased, the tunnel engineering as a concealed engineering has many unsafe factors, and tunnel monitoring can be used for stability analysis and deformation quantity test of a tunnel internal structure in a tunnel excavation process.
The main method currently applied to monitoring horizontal convergence and vault settlement of the tunnel is to use a total station and a reflector for monitoring. The method has the characteristics of simple measurement, easy embedding of the measuring points, low cost and the like, but the existing monitoring measuring point device still has defects in the using process, for example, when the embedded rod with the expansion bolt arranged at the bottom is inserted into the embedded hole, part of air is blocked in the hole and cannot be removed, so that the embedding depth of the embedded rod is not enough; the method has the advantages that the depth of the holes punched in the embedding process of the embedded rods is not uniform, so that the embedded rods are not fixed; the cylindrical solid bodies with the same height of the existing embedded rods are not beneficial to the cementation between the embedded rods and the hole walls after the embedded rods are embedded, so that the embedded rods are unstable after installation, and the measurement precision is reduced; the reflector is extremely easy to be damaged in the construction process, and when the reflector is damaged, the reflector needs to be embedded again, so that the workload and the monitoring cost are greatly improved. Therefore, a novel tunnel engineering deformation monitoring measuring point device is needed.
