    Corrosion of weathered granite to dredging pipeline

    Whether the weathered granite is corrosive to the dredging pipeline

    In dredging engineering, pipeline is dredging construction of main auxiliary equipment, the construction of wear is a common physical phenomenon, the usual practice is to change the new, even in order to save costs, repair of conveyor pipelines in the wear part is also need high cost and delay a lot of construction time, reduce time utilization, affect the efficiency of construction, in the construction project cost management, along with the deepening of the management process shall be of pipe wear are discussed. In dredging engineering, pipeline wear is influenced by conveying pressure, concentration, velocity, transport characteristics of rock and soil, pipeline material, pipeline roughness and fluid movement state.

    In severe cutter suction dredger conveying weathered granite as an example. It is pointed out that the transport process in pipeline wear often occurs in parts of the pipeline shaped component, such as elbow, tee, water and water tube junction and land and water pipe joint etc.. The wear and tear in the pipeline can be divided into three types: friction and wear, impact wear and cutting wear. The analysis and evaluation of the relationship between soil properties and wear types of transport, from the angle of the transport of soil properties to investigate the law of sediment movement and pipe wear.
