Abstract

The invention discloses a multi-suspended span across-river oil transmission pipeline mechanics experiment device for internal and external flows. The mechanics experiment device comprises a support bench. A high-level water tank and an arc-shaped rail are arranged on the support bench. A water pool is arranged on the right side of the support. A water inlet-outlet is arranged in the high-level water tank. The right end of the rail is arranged right below the water inlet-outlet. The right end of the rail is arranged in an inner cavity of the water pool. A support is arranged in the water pool. A pipeline is installed on the support. A strain sheet is arranged on the pipeline. According to the invention, movement of sediment, pebbles and fluid in the pipeline in flood is considered and the mechanics experiment device is capable of carrying out simulation tests on pipelines similar to 'multi-span beams' in different naked degrees.

Description

technical field

[0001] The invention relates to the design of an oil pipeline, in particular to a mechanical experiment device for a multi-span oil pipeline crossing a river for internal and external flow. Background technique

[0002] The oil pipeline is an important part of the national lifeline project and the main artery of the country's energy. Its safe operation has a great impact on the country's economic development. Due to the influence of various reasons, the existing pipeline design codes have deficiencies in the design of pipelines crossing rivers, and it is necessary to carry out systematic research on this issue, among which experimental research is an important aspect, and the experimental bench is the guarantee for carrying out experimental research . However, in the actual problem of large-scale crossing pipelines, the flow velocity of the flood and the degree of exposure of the pipeline are not constant, especially for the experimental testing of pipelines...
