The dredging spiral steel pipe adopts the technology of submerged arc welding, also called submerged arc welded straight seam steel pipe. The main function is to clean up the steel pipes that transport sediment, mud and other mixed debris. The purpose is to excavate port basins, access channels, etc., reclamation and reclamation to build wharfs, port areas and port-facing industrial areas, coastal urban land and recreational and leisure land, shore and beach maintenance, water conservancy and flood control, and reservoir area dredging, rivers and rivers. Improvement and ecological restoration of water environment such as lakes and seas, as well as construction and landfilling of various underwater pipeline trenches.

Dredging spiral steel pipes are widely used in beaches, rivers, waterways, urban environmental protection, engineering construction and other fields.

Common matching machinery and equipment for dredging spiral steel pipes

①The dredger is divided into mechanical type and hydraulic type according to the working principle and soil material conveying method. Mechanical dredgers use buckets or shovels to dig and lift soil directly from the water, including chain bucket, grab, bucket, bucket wheel, etc. Hydraulic dredgers use high-pressure water to flush the mud or cut the mud with a reamer and a rake head, and then use a mud pump to suck the mud and transport it through the dredging steel pipe. It is also called a suction dredger. , No reamer type, pneumatic type, etc. Dredgers are divided into self-propelled and non-self-propelled types, and non-self-propelled dredgers need to be hauled by tugboats.

②Water work vessels, such as surveying vessels, crane vessels, drilling and blasting vessels, anchor boats, etc.

③ Auxiliary ships, including tugboats, oil barges and fresh water barges and other supply ships, mud barges, barges and lifeboats, etc.

④ Buoys, pipelines and other ancillary equipment. When selecting dredging equipment, first select the main dredger, and then equip other auxiliary vessels to form a dredging fleet.
