Problems solved by technology
However, during the construction of the tunnel, the lighting conditions are poor, and the dust concentration in the tunnel is high. During the monitoring and measurement work, it is often impossible to find the monitoring point in time, which greatly reduces the measurement efficiency.
[0003] In the construction of tunnel engineering, there are many cases of spraying concrete in the tunnel, and the dust concentration in the tunnel is high, which is not easy for surveyors to find. Moreover, during the construction of the tunnel, the operators and construction machinery are likely to damage the hanging rings and reflective stickers of the measuring points by mistake.

Embodiment
[0050] Such as Figure 1 to Figure 4 ,, This embodiment provides a tunnel convergence measuring instrument installation assembly, which is mainly used for installing the convergence measuring instrument so as to monitor the convergence of the surrounding rock on both sides of the tunnel. The above-mentioned installation components mainly include a base and a connecting piece, the base is used for connecting with the wall of the tunnel; the connecting piece is used for connecting the measuring instrument.
[0051] Specifically, the base includes a seat body 2 and a fixing rod 1, and the fixing rod 1 is used to fix the base as a whole on the tunnel wall. The fixed rod 1 includes expansion bolts. During installation, anchor holes are first drilled on the side wall of the surrounding rock of the tunnel, and then the fixed rod 1 is integrally packed into. The base as a whole is a quadrangular pyramid structure, including a large end face and a small end face, the large end face an...

The invention provides a tunnel convergence measuring instrument mounting component and mounting base and belongs to the field of tunnel monitoring and measuring. The tunnel convergence measuring instrument mounting component comprises a base and a connector and is characterized in that the base comprises a base body and a fixing rod, and a connecting groove, the fixing rod and a self-luminous tritium tube are arranged on the base body; the connector is used for being connected with a measuring instrument; the connector comprises a fastener which is connected with the connecting groove in a clamped manner. When the tunnel convergence measuring instrument mounting component is used, the fixing rod is fixedly connected with a tunnel rock wall, and then the connector is connected with the base body; during measuring, the tunnel convergence measuring instrument is mounted on the connector. Due to the fact that the base body of the base is provided with the self-luminous tritium tube, measuring staff can conveniently find the mounting component, and the measuring instrument can be mounted conveniently.
Description
technical field [0001] The invention relates to the field of tunnel monitoring and measurement, in particular to a tunnel convergence measuring instrument installation component and installation base. Background technique [0002] In tunnel engineering construction, in order to protect the safety of tunnel construction, it is necessary to monitor the convergence of surrounding rock on both sides of the tunnel. The usual practice is to set up a measuring point device at the monitoring site, and use a total station or an extensometer to measure its horizontal distance regularly. However, during the construction of the tunnel, the lighting conditions are poor, and the dust concentration in the tunnel is high. During the monitoring and measurement work, it is often impossible to find the monitoring measurement points in time, which greatly reduces the measurement efficiency. [0003] In the construction of tunnel engineering, there are many cases of spraying concrete in the tun...
