Description

TECHNICAL FIELD

[0001] The utility model relates to monitoring equipment technical field, especially a kind of support rod of tunnel pavement state monitoring equipment. BACKGROUND

[0002] The support rod of tunnel pavement state monitoring equipment is a device for providing support and fixation for tunnel pavement state monitoring equipment, which is generally composed of a vertical column standing vertically on the edge of the road to provide stable support, and a crossbar arranged transversely on the top of the vertical column to bear the monitoring equipment. Some crossbars are also equipped with connecting pieces for quick installation and fixation of the equipment. The monitoring equipment can be stably placed in the appropriate position, and the auxiliary equipment can complete the pavement state monitoring work, helping to ensure the safety of driving in the tunnel.

[0003] When installing the pavement state monitoring equipment, the support rod is usually installed and fixed first, and then the worker is lifted to the position of the crossbar using a lifting vehicle, so that the worker can use bolts to fix the pavement state monitoring equipment. This results in low installation efficiency of the pavement state monitoring equipment, especially for tunnels that have been opened to traffic. When installing the pavement state monitoring equipment, the normal lane needs to be occupied, which seriously affects the normal traffic of vehicles and may even cause traffic accidents.
