This material is wear-resistant, corrosion-resistant, UV-resistant, light-weight, and high-strength, and can meet the strength and reliability requirements of long-term work at sea, and meet the need for one side of the airbag to be reused.

[0010] A method for using a submarine cable floating device with an ignition device comprises the following steps:

[0011] 1) The floating device is transported to the construction sea area by a construction ship, and the submarine cable is placed on the floating sheet between the two air bags of the floating device;

[0012] 2) As the submarine cable is slowly released into the sea, a floating device is arranged at intervals to ensure that the submarine cable floats steadily on the sea surface;

[0013] 3) After the landing construction of the submarine cable is completed and the position of the submarine cable is adjusted according to the pre-set laying route, the ignition transformer discharges to generate sparks to burn the connecting buckle and burn the airbag where it is located. After the airbag is burned, it is quickly deflated, and the submarine cable can sink into its routing line from the side of the deflated airbag;
