Temperature control method for hot work in shield tunneling machine cutter body reinforced by freezing

The invention discloses a temperature control method for hot work in a shield tunneling machine cutter body reinforced by freezing. The temperature control method comprises the following steps that 1,the preparation of low-temperature freezing water and the formation of the shield tunneling machine cutter body reinforced by freezing are carried out; 2, a monitoring point and an installation sensor are arranged in the body reinforced by freezing; 3, a fire insulation layer is laid; 4, a muddy water bin partition board is arranged as a cold plate; and 5, an air replacement device is installed.According to the temperature control method for the hot work in the shield tunneling machine cutter body reinforced by freezing, the design is reasonable, the fire insulation layer is arranged on thebody reinforced by freezing on the tunnel face and on the shell of the shield tunneling machine anterior shell through the arrangement of the monitoring point, the muddy water bin partition board is arranged as the cold plate a
