HDPE Pipe Side Ditch Detail Plan With 300mm Trench Section Layout

This HDPE pipe side ditch detail plan drawing presents a sectional construction layout showing the installation of an HDPE pipe within a trench beside a roadway or throughway. The drawing labeled detail B with scale 1 to 20 illustrates a pipe placement section using HDPE D112 or 90 pipe positioned inside a compacted trench structure. The trench width is approximately 300mm, and the section height is about 300mm, which provides adequate structural space for pipe installation and bedding layers. The drawing clearly shows layered construction, including the base bedding layer of approximately 100mm thickness, followed by compacted fill material surrounding the HDPE pipe. Vertical measurements such as 94mm, 112mm, and 94mm indicate the structural spacing around the pipe within the trench profile. This HDPE pipe side ditch detail plan provides a clear reference for pipe placement and protective covering in drainage or utility installations.
