Description
corrugated pipe allowable deformation
These years in the domestic application, our company in the cross section deformation have been studied, because the corrugated pipe is a flexible tube, because both sides of the soil pressure, the pipe in longitudinal direction would be higher than diameter 2-5cm, when filled to the top tube 9 meters, tends to be circular, in some high embankment, shall ensure that the wedge part and both sides of the back filling of good,corrugated pipe deformation at around 2%,the size of the deformation depends directly on the backfill material, should choose good mechanical properties of sand, gravel, Graded Macadam or fine stone concrete,compactness meets the requirements, the deformation of the tube body is very small, the recent my company in Henan, Sanmenxia to do the 5 meters in diameter, four holes side by side, culvert length of 780 meters, the embankment height 32 meters, has been filled to 32 m tall, tube deformation 2--10cm.
