Single-soldier-equipped integrated fire-fighting bomb throwing system and throwing method

The invention discloses a single-soldier-equipped integrated fire-fighting bomb throwing system and throwing method. An installing structure is arranged at the bottom end of each fire-fighting bomb, each fire-fighting bomb is rotationally installed in a corresponding launching barrel, multiple launching barrels are installed on a launcher support, multiple fire-fighting bombs can be carried at a time, and the explosive load is two times or above of that of existing equipment; and the fire-fighting bombs are kept stationary under the combined action of an installing positioning assembly, launching barrel sealing covers and air in a low-pressure air chamber. When the air pressure is continuously increased and exceeds a pressure threshold, pressure in the low-pressure air chamber is higher than the sum of shearing force borne by the installing positioning assembly and shearing force borne by the launching barrel sealing covers, and pressure of the air pushes the fire-fighting bombs to be launched from the launch
