Description

Technical Field

[0001] This utility model relates to the technical field of crushed stone bed leveling devices, specifically to an experimental device used for leveling crushed stone beds. Background Technology

[0002] In marine engineering construction, leveling the crushed stone foundation is a crucial step in ensuring the stability of the foundation structure. Traditional underwater crushed stone foundation leveling typically involves placing stones from surface vessels, followed by deploying a leveling robot to perform the leveling operation. Common leveling methods include scraper leveling and spiral scraper leveling. However, with increasing water depth, the surface elevation difference of the foundation after underwater stone placement increases significantly, posing a serious challenge to the applicability of traditional leveling robots. This also necessitates systematic experimental verification of the leveling effect of newly developed robots to allow for targeted improvements in the robot's structural design and operating methods.

[0003] Currently, experimental setups for leveling crushed stone beds have significant shortcomings. Existing setups often lack mechanisms for breaking up and gathering the crushed stone. After each round of testing, researchers must manually break up or gather the leveled stone using tools. Since crushed stone bed leveling experiments require multiple rounds of testing, the repeated work of gathering and gathering the stone is time-consuming and labor-intensive. Utility Model Content
