The device is adopted to control the sliding of the large-diameter pipeline:
(1) pipe laying
In the process of controlling the laying of the pipeline, the pipeline is firstly penetrated into the clamping hole between the upper steel hoop and the lower steel hoop, and the lower surface of the pipeline is in close contact with the lower steel hoop by utilizing the dead weight of the pipeline. And then, feeding oil into the oil cylinder of the upper jack 7, and utilizing jacking force generated by the upper jack 7 to press the upper steel hoop downwards to enable the upper steel hoop to move downwards along the guide column 2 until the upper arc-shaped groove 5 of the upper steel hoop is in close contact with the upper surface of the pipeline.
(2) Pipeline holding tightly
After the large-diameter pipeline is tightly contacted with the rubber gasket 10 between the upper steel hoop and the lower steel hoop, the oil feeding valve of the oil cylinder of the upper jack 7 is closed, and the position of the upper jack 7 is limited. And opening an oil feeding valve of the lower jack 8, feeding oil into an oil cylinder of the lower jack 8, and jacking the lower steel hoop to move upwards along the guide column 2 by utilizing jacking force generated by the lower jack 8. And simultaneously observing the magnitude of the jacking force generated by the lower jack 8, and stopping oil feeding into the lower jack 8 when the jacking force generated by the lower jack 8 reaches the control force required by tightly holding the pipeline, so as to stop pushing the lower steel hoop to move. At the moment, the pipeline is firmly fixed by the upper steel hoop and the lower steel hoop, and the pipeline cannot slip and release with the large-diameter pipeline to control the clasping device to generate relative displacement, so that stable working conditions are provided for the next construction operation of the pipeline.
