[0029] A plurality of fixing members 4 are sequentially arranged along the axial direction on the flexible traction cable 2 , and each fixing member 4 is connected to a counterweight 5 so that the aeration hose 1 sinks to the bottom of the tank body 10 . The head end of the aeration hose 1 is connected to the air supply main pipe 7 through the first air supply branch pipe 6 .

[0030] During the laying process, a tool similar to a hull can be used to float on the water body, the counterweight 5 can be fixed together with the flexible traction cable 2 through the fixing piece 4, and then the limit piece 3 can be fixed together with the flexible traction cable 2, and the aeration hose 1 can be inserted into each limit piece 3 in turn, so that the flexible traction cable 2 and the aeration hose 1 are fixed, and the two extend in the same direction. As the hull moves forward, the assembled device is continuously placed in the pool body 10 and sinks to the bottom under the action of the counterweight 5. During the entire operation, it is only necessary to always pull the flexible traction cable 2 along the laying path and gradually put it into the pool body 10 to complete accurate laying and prevent path deviation. In the case of no drainage, the aeration hose 1 can be sunk to the bottom of the pool body 10, the hull moves to the end of the pool body 10, and the head end of the aeration hose 1 is connected to the air supply main pipe 7 through the first air supply branch pipe 6, and the air supply of the blower can enter the aeration hose 1.
