| description | The invention discloses a tunneling construction method for a super-large-section reloading chamber. The method adopts a roadheader for tunneling construction, and specifically comprises the followingsteps that (1) a chamber external measure roadway is constructed from a shaft bottom passenger station to reach the central position of the top arch of the reloading chamber; (2) first-layer tunneling pilot tunnel construction is performed from the central position of the top arch of the reloading chamber to form a semicircular arch top plate; (3) a thin spray material is sprayed on an anchor netarranged on the semicircular arch top plate for reinforcement; (4) a ventilation ramp communicated with the exit of the reloading chamber is formed by tunneling in the reloading chamber to achieve full-air-pressure ventilation; and (5) tunneling construction is performed downwards through a step layering method to finally reach a designed bottom plate height to complete reloading chamber construction.
