Труба содержит поперечные гофры 1,2, выполненные на верхней и нижней част х поперечного сечени трубы . Между верхними и нижними гофрами 1 и 2 расположен участок гладкой трубы 3, высоту которого определ ют по соотношениюThe pipe contains transverse corrugations 1.2, formed on the upper and lower parts of the pipe cross section. Between the upper and lower corrugations 1 and 2 there is a section of smooth pipe 3, the height of which is determined by the ratio

Труба работает следующим образом .The pipe works as follows.
Гофры 1 и 2 создают наибольшую жесткость труб в горизонтальном направлении , а наличие участков гладкой трубы 3 позвол ет допускать значительные, деформации изгиба в вертикальной плоскости.The corrugations 1 and 2 create the greatest rigidity of the pipes in the horizontal direction, and the presence of sections of the smooth pipe 3 allows for considerable bending deformations in the vertical plane.
Предлагаема труба имеет повышенную надежность при прокладке трубопроводов на просадочных и ..мерзлых грунтах оThe proposed pipe has increased reliability when laying pipelines on subsiding and .. frozen soils on
