Abstract
The invention discloses an underwater pipe arranging device which is characterized in that a roadbed pipe-jacking fixing part is provided with a jack group which is connected with an underwater injection digging part through a welded steel pipe part; the underwater injection digging part is connected with an overwater positioning part through a connecting steel cable; a bank water pumping part is connected with the welded pipeline part through the pipeline. The invention ensures all the welding work to be finished on bank and adopts the pressure water injection and the buoyancy of the steel pipe to finish the ditch groove digging and the positioning work so that the water flow resistance and the wind wave resistance are strong; the influence of the variable water level is small; the climatic adaptation is strong. The water quantity in the welded steel pipe part can be controlled through the water depth scale, a jet flow water-supply pump and a temporal water-pumping and diving pump; the depth of the ditch groove can be accurately controlled through the buoyancy of the welded steel pipe part; the welded steel pipe part and the underwater injection digging part can be sunk into the ditch groove to reduce the influence on the pipeline from the water flow when the construction is temporally paused. The overwater positioning part is not only used for ensuring the power supply and control of the jet flow water-supply pump, but also used for the deviation correction when the pipe position has deviation.
