While passing through waterbodies the pipeline crossings are affected by the inward flow. It might lead to soil erosion near it, and objects floating in this flow can cause damage of the pipeline, increasing risks of collapse. There are several types of protective coatings that are used on the pipelines, including the flexible protective concrete pavement (mats). Experience has shown that partial erosion of soil foundation can cause flipping of the blocks in first row of the protective coating that would result in its wrapping. This article presents the results of experimental research of hydraulic characteristics of water flow while flowing over two types of flexible concrete mats UGZBM-S and UGZBM placed crosswise the inward flow, that protect the pipeline. We’ve also determined the levels of free surface above differently buried pipeline crossings protected with two types of flexible concrete pavements under the conditions of stationary inward flow.
