The invention specifically relates to an energy-saving
rapid construction method for ventilating shafts of tunnels, which solves the problem that shortcomings exist in the construction on the existing ventilating shafts of tunnels by using a downward driving method. The method comprises the following steps of: a, measuring the position of a positioned shaft; b, carrying out strengthening construction on the geologic status of a shaft mouth, meanwhile, excavating a vertical
ballast-
discharge hole downwards from the shaft mouth, and carrying out excavation from the front hole of a tunnel to the position of the shaft until the excavating position meets the vertical
ballast-
discharge hole; c, carrying out shaft excavation by using a
drilling and blasting combined method; d, when the shaft is excavated to a certain depth, carrying out secondary lining construction on the upper part of the shaft, wherein the secondary lining construction and the shaft construction are performed synchronously; and e, installing a shaft ventilating device. According to the invention, through adopting a mode of carrying out equidirectional and synchronous operation flow on the shaft excavation construction and the shaft secondary-lining construction, the method has the significant advantages of small
safety risk, high construction speed, high working efficiency, energy saving, consumption reduction, easiness in construction drainage in shafts, low comprehensive construction cost, and capabilities of reducing the equipment investment, saving the occupied land and the cost of ecological restoration
engineering, and obviously improving the construction work environment.
