Recommendations for designing cellular wall polyethylene pipes placed in the soil

Abstract

Information about various Ukrainian and international national standards in the field of design and installation of polymer pipes with hollow walls is given. The strength of cellular wall polyethylene pipes placed in the soil is calculated. The choice of the calculation formula for determination of relative pipe deflection depending on the features of its operation is substantiated. The critical deflection of such structures on this basis is determined, therefore, it is recommended to calculate the strength of the cellular pipes placed in the soil according to the size of deflection, which should not exceed the critical value.
