AI Technical Summary
Existing underwater silt rheological property testing devices exhibit significant size effects, making it difficult to reproduce the actual underwater silt flow path. They do not integrate slope and gravel cushion layers, cannot reproduce the effects of multi-boundary coupling, and are difficult to clearly capture the flow pattern of silt. They are also not recyclable and do not meet the requirements of green, low-carbon and environmentally friendly practices.
A device was designed that includes a perspective test tank, a immersion area, and a silt collection area. It is equipped with a crushed stone cushion layer and a slope, and features pressure sensors, ultrasonic flow meters, cameras, etc. The device simulates the installation of immersed tubes through hoisting components, reproduces the effects of multi-boundary coupling, and utilizes a silt collection system to achieve recycling.
It has achieved large-scale experiments, accurately reproduced the underwater silt flow path, reproduced the effects of multi-boundary coupling, clearly captured the flow pattern, supported the recycling of silt, and met the requirements of green, low-carbon and environmental protection.
