There are few basic occupational diseases. I am now in charge of a shield interval survey. Except for the new comrades who just started working in the tunnel, measuring in the tunnel may not adapt to dizziness. This is caused by the sweltering heat in the tunnel and the relatively little oxygen outside. I will get used to it in a day or two. The main duties of the survey team in the tunnel are to control the wires in the tunnel, do a good job of moving stations and often measure the posture of segments. We are. In the process of excavation, we are afraid of geological or survey factors, and the excavation is out of tolerance. We should find out the reasons in time and deal with them, draw a survey conclusion, and remind drivers to rectify the excavation. The safety of the surveyors in the cave is also the most important. When the battery car travels back and forth in the hole, it is necessary to prepare warning lights and pay attention to avoiding them. When the total station moves to the station, the hanging basket needs to be punched and inflated, and the hanging basket needs to be dismantled on the ladder for aerial work. Be careful. You can communicate with the project department, dismantle the hanging basket and let the workers do it. The rest is the safety of instrument disassembly. If it has problems, it can't be excavated. This is my personal experience, I hope to adopt it! Good luck with your work!
