Standard Practice for Installing Corrugated Aluminum Structural Plate Pipe for Culverts and Sewers

This standard provides guidance on the installation of corrugated aluminum structural plate culverts and sewers, focusing on both trench and embankment scenarios. The installation practice ensures that the structural performance of buried conduits is optimized by considering the interaction between flexible pipes and compacted surrounding soils.

Key requirements and specifications:

• Ensures correct procedures for trench and embankment preparation

• Specifies soil quality and compaction for optimal load resistance

• Requires detailed bedding design to maintain uniform support beneath pipes

• Outlines step-by-step assembly processes for field-bolted plate pipe systems

• Provides guidelines for field verification of soil structure (e.g., density testing)

• References laboratory compaction and field density tests to ensure compliance with project specifications

Who should comply? Civil engineers, contractors, public works personnel, and maintenance teams involved in road, rail, drainage, and sewer projects where structural plate pipes are used.

Practical benefits:

• Minimizes risk of early infrastructure failure due to settling, poor bedding, or inadequate compaction

• Reduces maintenance frequency through improved structural reliability

• Supports compliance with safety, health, and environmental regulations

Key highlights:

• Focuses on field practices for lasting structural performance

• Integrates with related standards for buried conduits (e.g., Practice B790/B790M)
