Backfill Detail 300mm Width 790mm Height HDPE 65 by 50 DWG file

The Backfill Detail 300mm Width 790mm Height HDPE 65 50 DWG was prepared with precise sectional representation for underground service installation. This AutoCAD 2D drawing clearly illustrates a 300mm wide trench section with a total height of 790mm, including layered backfill composition. The detail shows an HDPE pipe 65 50 diameter placed over a compacted base, surrounded by sand bedding and a brick protective layer. Dimension markings include 50mm, 65mm, 100mm, and 150mm vertical layer divisions, along with a 640mm sloped profile reference for ground level. The sectional hatch patterns distinctly identify backfill soil, sand cushion, brick cover, and pipe positioning for construction accuracy.
