Abstract

The invention discloses a shield tunneling machine with a freeze-reinforcing function, comprising a cutter, a cutter main tool beam arranged on the cutter, a shield, a center rotary connector, and a freezing unit; the center rotary connector is provided with a charging passage and a discharging passage; a cutter freezing circulating pipeline is distributed on the cutter, an inlet of the cutter freezing circulating pipeline is communicated with an outlet of the charging passage in the center rotary connector, an inlet of the charging passage is communicated with an outlet of the freezing unit, an outlet of the cutter freezing circulating pipeline is communicated with an inlet of the discharging passage of the center rotary connector, an outlet of a discharging pipeline is communicated with an inlet of the freezing unit, the shield is provided with a shield freezing circulating pipeline, an inlet of the shield freezing circulating pipeline is communicated with the outlet of the freezing unit, and an outlet of the shield circulating pipeline is communicated with an inlet of the freezing unit. Waste soil in a tunnel face and a soil chamber is freeze-reinforced through the cutter freezing circulating pipeline and the shield freezing circulating pipeline, and workers may the chamber to perform operating just after reinforcing.

Description

technical field [0001] The invention belongs to the field of tunnel shield machine equipment, and in particular relates to an earth pressure and mud-water balance shield machine capable of freezing and strengthening strata. Background technique [0002] At present, the tunnel excavation process of the earth pressure and mud-water balance shield machine is a tunnel construction method in which the cutter cuts the tunnel face while digging and supporting. Therefore, the shield machine will have cutterhead and cutter wear during the shield tunneling process. If it is damaged, it needs to be shut down for maintenance or to replace the tool. When personnel enter the warehouse to work, it is necessary to reinforce the working surface to avoid major accidents such as casualties caused by the collapse of the working surface. In the prior art, the operation of entering the soil bin generally adopts the method of entering the bin with pressure or ground reinforcement. Pressurized si...
