Underwater pipe device and method thereof

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.

Description

Technical field: [0001] The invention relates to an underwater piping engineering equipment, in particular to an underwater piping equipment for excavating and arranging medium and large-diameter water supply and drainage pipes in riverbeds of large-area water bodies such as rivers and lakes, and underwater piping equipment thereof method. Background technique: [0002] At present, the water intake projects of waterworks that take water from the far shore of large-area water bodies such as rivers and lakes and the urban sewage projects that drain water from the far shore of large-area water bodies need to arrange medium and large-diameter pipes from the riverbed. Considering safety and inconvenient maintenance, the pipe materials are general Using steel pipe. The main difficulty of traditional underwater piping lies in the large workload of underwater excavation using large-scale special machinery, the difficulty of controlling the position and elevation of the trench, and ...

AI Technical Summary

Problems solved by technology

The main difficulty of traditional underwater piping lies in the large workload of underwater excavation using large-scale special machinery, the difficulty of controlling the position and elevation of the trench, and the difficulty of water transportation of the pipeline. The amount of work on the water is heavy, and if the Huff joint is used, the cost of the joint itself is high

In addition, large-scale water bodies such as rivers and lakes often have large annual water level changes, and the pipe drainage project is easily affected by factors such as water flow, wind and waves, and can only be constructed during the dry season of the year and when the wind and waves are small, and there are many construction restrictions.
