Abstract
The invention provides a method for preventing a partition from biasing in a tunnel. The method comprises the steps as follows: driving a movable reinforcing truss trolley to a preset position at current construction section through a driving motor; adjusting a transverse reversed H-shaped steel to prop against an initial support at one side of a guiding hole and an intermediate partition at the other side of the guiding hole in the current construction section in the tunnel; dismounting the transverse reversed H-shaped steel of the current construction section after finishing the construction; and carrying out the construction of the next construction section. According to the method, the circulating flow process has a large number of turns, so that the repeated utilization rate can be increased, and the quantity of used profile steels can be reduced; a reinforcing supporting point is conveniently mounted and dismounted, and the mounting time is short; the transverse reversed H-shaped steel is positioned through a level guiding channel steel, so high accuracy is achieved; and the tension of the transverse reversed H-shaped steel is adjusted through a lead screw, thereby the work of calculating the blanked materials can be effectively reduced.
