The weight m of G1, the weight G2 of tracheae 2 and pendant block 5, when generated buoyancy F1 and tracheae 2 are full of air when float tube 3 is full of air
Generated buoyancy F2, designs the structure size of pipe-line system, so that G1+G2+m=F1+F2；
The air bag 16 of water pumping aerator 1 is inflated, so that the buoyancy that air bag 16 generates is slightly less than water pumping aerator 1 and exists
Water pumping aerator 1 is placed in water by the gravity in water, so that water pumping aerator 1 is in state to be sunk；
Original state closes all valves in pipe-line system, then opens tracheae intake valve 10 and float tube intake valve 13,

The Pipe-lining methods that the utility model uses are that the improved laying of a kind of pair of conventional pipelines laying and construction method is applied
Work method, after connecting together tracheae with aerator in conventional method, with the sinking of aerator, the end of tracheae is also sunk to
In water, starting constantly increase pendant number of blocks at this time makes its quick submerged to complete the laying of pipeline.It is this directly under
Under heavy laying and construction method is longer in feed channel and the biggish situation of the depth of water, it will cause the bending deformation of pipeline, be easy because of shape
Become and gas leakage.The laying and construction method of the utility model is then that by pipeline and pendant block, all assembling is finished on the water surface, with exposure
The sinking watching of gas device, it is only necessary to be adjusted by air compressor machine air and guarantee the i.e. certifiable pipeline of pipeline buoyancy with aerator together
Sink, finally pipeline buoyancy is removed in water filling, completes laying.
The method of the utility model is solved since pipeline is larger and lead by pendant block pulling force during flood depth reservoir construction
