Method of treating tunnel collapse with roof-contacted shield support
A method of treating tunnel collapse includes mounting a shield plate, a column, a support column to form a combined support and moving the combined support onto an operation platform, lifting up the combined support, and enabling the height of canopy to be greater than the height of an initial supporting arch. Actively contacting a surface of a collapse cavity by a fixed support column and bearing a load, and lifting a movable support column to the top of the collapse cavity and bearing a load. Mounting an initial supporting arch, and welding the initial supporting arch with the support column. Removing a hydraulic prop after the support column contacting the initial supporting arch is cut off and the load of the shield plate is transferred to a supporting shed. Mounting an exhaust pipe and a filling material pumping pipe, and pumping a filling material into a collapse cavity space.
