AI Technical Summary

Technical Problem

Existing rock-dumping leveling vessels have shortcomings in terms of leveling efficiency and applicability, especially in their inability to efficiently level foundation beds that are close to or located in prefabricated docks, and manual leveling is inefficient.

Method used

A rock-throwing leveling vessel is designed, employing a leveling actuator that combines a large traveling trolley and a small traveling trolley. By setting flip positions above and outside the moon pool, the leveling actuator can be flipped to enter the first and second working states respectively, making it suitable for leveling the base bed within and outside the moon pool.

Benefits of technology

It improves leveling efficiency and range, and can efficiently level the base bed within and outside the moon pool. It has a wide range of applications, a simple structure, and convenient flipping control.

Abstract

The present application relates to a kind of riprap leveling boat and gravel bed leveling construction method, belong to bed leveling technical field.The riprap leveling boat includes hull and leveling device;Hull middle is opened with moon pool;Leveling device includes travelling car, travelling trolley and leveling actuator;Travelling car one end extends to moon pool outside, and travelling car is equipped with first turnover position and second turnover position;Wherein, leveling actuator is overturned by travelling trolley in first turnover position and second turnover position, to make leveling actuator convert between first working state, second working state and non-working state;When first working state, leveling actuator carries out leveling work to the bed in the moon pool surrounded range;When second working state, leveling actuator carries out leveling work to the bed outside the moon pool surrounded range;When non-working state, leveling actuator is overturned to the moon pool above.The riprap leveling boat, and leveling efficiency is higher, and widely applicable.
