GRAB DREDGE Meaning and
Definition
-
Grab dredging refers to a method of excavating and removing sediment or material from the bed of a water body using a mechanical device called a grab bucket. The grab bucket, also known as a clamshell bucket or simply a grab, is a hinged tool consisting of two hinged shells or buckets that are operated by hydraulic power.
In the process of grab dredging, the grab bucket is lowered onto the bottom of the water body, allowing the open shells to scoop up and collect the desired material. Once the material is secured within the bucket, it is lifted and transported to another location, usually a barge or a disposal site. The material can consist of various substances such as sand, silt, gravel, or even debris like rocks or rubbish.
Grab dredging is commonly used for various purposes including maintenance of waterways, harbor deepening, and land reclamation projects. It is particularly effective in areas with loose or soft sediments that can be easily excavated by the grab bucket. The size and capacity of the grab bucket can vary depending on the specific project requirements.
This method of dredging offers advantages such as versatility, as the grab bucket can be easily adapted to different requirements, and efficiency, as it allows for precise control over the excavated material. Grab dredging is widely employed in marine construction and engineering projects, and it plays a crucial role in ensuring safe and navigable waterways.
