Mud concentration type shield tunneling construction method for shield tunneling machine
The invention relates to a mud concentration type shield tunneling construction method for a shield tunneling machine. According to the method, an excavating surface and an over-excavation part are pressurized and filled with thick mud to form a mud film layer, so that the accidents of surface subsidence, upheaval and the like can be completely eliminated, construction accuracy is well improved, and the cost is reduced; a plasticizer is added, and a lubricating layer is maintained, so that long-distance tunneling, sharp curve tunneling and rock stratum tunneling are facilitated; working shafts are reduced, working efficiency is improved, and the cost of a construction period is reduced; a vacuum mud discharging manner is adopted, so that low workload and high safety are achieved, forced ventilation in a tunnel can be driven, and harmful gas hazards such as gas in the tunnel can be completely eliminated.
