DEVELOPMENT OF INNOVATIVE DRAINAGE PIPE DESIGNS THAT REDUCE THE RISKS OF LOSS OF STABILITY IN DIFFICULT CONDITIONS.

The article shows natural and architectural analogies in which triangular and arched arches are the most stable. A new design of a drainage pipe with a cross section in the form of a Reulot triangle with an angular arch, related to cycloidal structures and increased stability, has been developed. Based on model studies, it was revealed that the arches in the form of half an astroid are the most stable, in this regard, a new design of a drainage pipe with a vault in the form of intersecting hyperbolas has been developed, which practically corresponds to half an astroid.
