How much ground load can the PE tube bear
The tests and verifications usually considered for PE pipes are for hydrostatic tests, and the load should be considered for all buried pipes. PE to pipe is no exception, the following together to understand.
Load refers to the external forces and other factors that cause internal forces and deformation of a structure or component. Or commonly refers to a variety of direct actions applied on engineering structures to make engineering structures or components produce effects, common are: structural dead weight, floor live load, roof live load, roof ash load, vehicle load, crane load, equipment dynamic load and wind, snow, ice, wave and other natural loads.
As a result of industry national standard did not undertake mandatory detection to the annulus rigidity of conduit, the reason is to give conduit itself pressure requirement is high, use material requirement is high, from theory and design experience value looks, his annulus rigidity is greater than the blowdown pipe of same wall thickness certainly. Therefore, it is necessary to add casing to protect the water pipe from excessive force when it passes through the load road, and the pavement and other non-load road are not affected. The embedding depth should not be less than 0.8 meters, and the freezing line should be considered in the north. The tests and verifications usually considered for PE pipes are for hydrostatic tests, and the load should be considered for all buried pipes. PE to pipe is no exception, the following together to understand.
