Pipe Bedding

Definition

Pipe bedding refers to the layer of material that the pipe is typically required to lay on to maintain a uniform layer of material. Bedding is used to help keep the pipe at a constant grade.

Purpose

The purpose of pipe bedding is to provide a stable and even base for the pipe, preventing it from shifting or settling over time. Proper bedding ensures that the pipe maintains its alignment and grade, which is critical for the flow of liquids and gases.

Examples of Use

• Sewer Systems: Bedding sewer pipes to ensure proper flow and prevent blockages.
• Water Mains: Providing a stable base for water distribution pipes.
• Gas Lines: Ensuring gas pipes remain at a consistent grade to avoid leaks and maintain safety.

Related Terms

• Backfill: Material used to fill the trench after the pipe is laid.
• Haunching: The area between the bottom of the pipe and the sides of the trench.
• Trench Shield: A safety device used to protect workers in the trench during pipe installation.

Notes

• Materials: Common bedding materials include sand, gravel, and crushed stone, selected for their stability and drainage properties.
• Installation: The bedding layer should be compacted and leveled before laying the pipe to ensure proper support.
