The invention discloses a rapid rescuing method for tunnel gateway collapse. The rapid recuing method comprises the following steps: I, installing spiral excavation pipe-jacking pipe curtain construction equipment provided with a spiral excavation function and an oil cylinder jacking function, and capable of simultaneously performing spiral excavation operation and oil cylinder jacking operation at a safety area in an excavated tunnel hole; II, arranging at least one steel tube capable of passing through a person on the bottom of a gateway collapse area in an the excavated tunnel by virtue of the spiral excavation pipe-jacking pipe curtain construction equipment, introducing the steel through into a construction operation area of the excavated tunnel after passing through the gateway collapse area, and forming an escape channel by the steel tube; III, directing the staff in the construction operation area to escape to the safety area from the escape channel. The invention belongs to a novel-use invention of the known product, the spiral excavation pipe-jacking pipe curtain construction equipment is transferred and applied to a tunnel collapse manual rescuing direction from the tunnel forepoling construction direction, so that the complexity of the tunnel collapse rescue is greatly lowered, and the tunnel collapse rescue speed is increased.
