Underwater intake trash-rack cleaning in China

The published reference

The supplied manufacturer brochure identifies an A-80 application at the Baihetan hydropower intake trash rack in China.

The task

Assess and clean suitable submerged intake surfaces using a remotely operated contact-cleaning platform.

The system to verify

A-80 vehicle and its cleaning attachment with external support equipment. Verify the pump, hose, attachment and actual substrate from the original project materials.

The reported outcome

For this project, the manufacturer reports wall-adhering travel and cavitation water-jet cleaning, without draining the water, stopping the facility or sending personnel underwater. These are project-specific manufacturer statements, not promises for every intake.

Evidence for a comparable project

• Rack spacing, angle, material and deposit type
• Cleaning attachment and pump/hose configuration
• Before-and-after evidence under comparable conditions
• Measured area, working time and substrate condition

What this reference establishes

The brochure identifies a relevant manufacturer application. It offers a starting point for asking about the technical approach and original evidence.

This reference does not demonstrate extraction of every type of large debris or a universal cleaning rate. Request the original operating record and a representative surface test.
