What should be paid attention to during dredger construction
During the construction of a dredger, there are several important factors that should be considered to ensure the successful completion of the project. These factors include: Design: The design of the dredger is critical to its performance and efficiency. The design should be carefully planned and reviewed by [...]
Qatar 2022 World Cup site preparation dredging project design
The Qatar Road Race Site Preparation Project is located in the north of Doha, Qatar, covering an area of about 35 km, with a length and width of 7 km × 5 km. The project achieves the purpose of coastline reconstruction through engineering measures such as wasteland reconstruction, new [...]
Application of water depth maintenance dredging technology model
For most ports formed by manual excavation, the shallow water depth caused by back-silting is a major problem faced by most ports, and even some ports have sudden siltation under the action of cold waves, typhoons, and even strong waves To ensure navigable water depth of the navigation area [...]
What is beach maintenance?
Beach maintenance refers to artificially replenishing the beach when the natural supply of sand on the beach is relatively insufficient, that is, placing a certain particle gradation of sand and gravel on certain eroded beaches by means of hydraulic or mechanical transportation. At the same time, depending on the [...]
Precautions for the use of high-efficiency and high-power mud pumping in dredgers
Due to its dredging, mud transporting, mud unloading, and other working processes, the dredger can be completed continuously at one time. It is a kind of dredging and dredging equipment with high efficiency and low cost. It is a good underwater excavation machine and is widely used. , then [...]
Causes of high bearing temperature of dredger
In recent years, dredgers have made considerable and steady development in dredging and dredging fields such as lake and river regulation. We often encounter various failure problems in the construction process. Today, let's introduce the reasons for the high bearing temperature of dredgers: the amount of lubricating oil is [...]
Classification of dredgers
Dredgers are mainly used for river dredging, sand dredging, land reclamation, road construction, etc., and they shine with the promotion of the ecological civilization construction. Classification of dredgers: cutter suction dredgers, trailing suction hopper dredgers, bucket wheel dredgers, chain bucket dredgers and bucket dredgers. Cutter suction dredger: Cutter [...]
Cutter suction dredger construction foundation
1.The maximum digging width of the steel pile dredger: the maximum digging width is limited by the length of the ship, generally, it is the total horizontal length of the ship during the construction (please remember that the vertical distance between the steel pile and the cutter head [...]
Development trend of the CSDs
Since the first CSD was born in the US in 1884, after 100-year development, the CSD has become the largest ship type in the dredger kingdom. At present, the CSDs are widely used in dredging constructions and land reclamation projects in ports and channels. With the rapid development of [...]
Construction Features of Large Cutter Suction Dredgers with Large Discharge Distance
Cutter suction dredgers are currently widely used in dredging constructions, which are using the front end of the suction pipe to install rotary reamer device around it to cut and stir the sediment at the bottom of the river, and then the twisted sediment material is transported to disposal [...]
History of the World Dredging Industry
With the continuous development of science and technology, dredging equipment and technology have been developed rapidly in the past hundred years, which can roughly be divided into three stages. The invention of the steam engine by Watt in Englandattheendof the 18th century triggered the industrial revolution in Europe and [...]
Preparation before dredging construction
Before dredging, we should first carry out a soil survey and understand the local hydrological and meteorological conditions. And we should also apply the theory of dredging and mud transportation, which mainly includes the setting of reamer excavation parameters and the matching of key parameters of centrifugal pump, mud pump, [...]
