Case study of pipeline failure analysis from two automated vacuum collection system

Area of Science:

• Environmental Engineering
• Mechanical Engineering
• Materials Science

Background:

• Conventional waste management poses environmental and hygiene challenges.
• Automated Waste Collection Systems (AWCS) offer an eco-friendly alternative by transporting waste underground.
• Pipe failures in AWCS can disrupt efficient waste management.

Purpose of the Study:

• To investigate the root causes of pipe failures in two distinct AWCS facilities.
• To identify and classify various failure phenomena within AWCS pipelines.
• To provide actionable recommendations for preventing common AWCS pipe failures.

Main Methods:

• Classification of 90 failure cases based on primary causes.
• Detailed analysis of failure phenomena.
• Computational Fluid Dynamics (CFD) simulation for failure analysis.

Main Results:

• Identification of specific failure origins and phenomena in AWCS pipes.
• A comprehensive classification of failure causes.
• CFD simulations provided insights into failure mechanisms.

Conclusions:

• Understanding pipe failure causes is crucial for AWCS reliability.
• Implementing recommended preventive measures can significantly reduce AWCS failures.
• AWCS technology presents a sustainable solution for municipal waste management when optimized.
