Proper soil support of the pipe is critical to the performance of both types of pipe, and proper inspection of pipe installation is essential in obtaining the required support. The bedding material is laid below the Condron Twinwall Pipe to provide uniform support and to permit small adjustment of the pipe’s line and level. Installation of pipe and specifically corrugated high density polyethylene (HDPE) pipe has historically been accomplished with the use of crushed granular materials, such as number 57 stone or a well graded crusher run material. The calculator compares the nominal diameter of a concrete pipe with the equivalent nominal diameter of a plastic pipe. . For example, the volume of a 10 metre long pipe with a radius of 28.7 cm is 2.46 cubic metres. How much will I need? Width and quality of contact between the pipe and bedding. CLASS F – PIPES LAID ON A BED OF SINGLE SIZE OR GRADED MATERIAL (BEDDING FACTOR 1.9) Appropriate where the depth of cover over the pipe requires a higher bedding factor: 20mm single size or 20 to 5mm graded granular material to conform to Tables B15-B17 of App B to BS EN1610; CLASS B – PIPES LAID ON GRANULAR MATERIAL (BEDDING FACTOR 2.5) SfA7: E5.2 (iii) Pipe Bedding / E5.4 (i) Pipe Surround Full bed and surround may not be required for rigid, large diameter pipes.

Spangler’s theory proposed that the bedding factor for a particular pipeline and, consequently, the supporting strength of the buried pipe, is dependent on two instal-lation characteristics: 1. These vary from moisture content to method of compaction. Driveways handle surface water by being permeable. . Precise values are shown in Figure C on page 15. The soil structure requirements for pressure pipe are less stringent than for gravity sewer pipe. soil calculations must be carried out for every installation technique modified to suit the results of that calculation. If the width of the top and bottom of the trench will be different then calculated Additionally useful volume C and volume of sloped sections D. Use our calculator to estimate how much you need.
