Аннотация

The article considers the bending of a long concrete pipeline when its section is raised to the free surface of a reservoir. The initial horizontal position of the pipeline is rectilinear. Its static bending occurs under the action of concentrated forces, the weights of the pipe and the transported medium, and the lifting force of water. The minimum required value of the lifting force and the corresponding length of the raised section of a long pipeline are determined. Taking into account the large ratio of this length to the depth of the reservoir, a linear bending equation is used. An analysis of the bend is given depending on the controlled lifting force and the controlled rise of the pipeline.
