The Practical Uses of Dredging

Many a times there is a need to move the earth beneath the water. This can be due to accumulation of wastes, presence of metals, uneven earth bed orremoving earth for construction. All of the requirements listed above can easily be achieved with the help of dredging. This advanced and state of the art technique of excavation is highly practical and it is now used by different industries and authorities around the world. This method utilizes the concept of agitation and vacuum pumping. Water is a mandate for dredging and it acts the medium for the creation and movement of slurry. First, the earth under the water body is agitated with the help of a cutter head. This results in the formation of slurry which is a mix of earth and water. This mixture is then moved to the exit point with the help of vacuum which is located right behind the cutter. The vacuum pressure is generated with the help of a slurry pump. There are many practical uses of this method and it comes as a relief for those who need to clean the beds of rivers, lakes and other water bodies. As one does not have to move the water before excavation, there is no extra cost involved and wide areas can be cleaned with dredging. Let us go through some. Land Reclamation Dredging can easily help in reclaiming land in low lying areas and places where coastal erosion is high. It can rebuild land where nothing existedand the Palm islands in Dubai are an example of how this process can be utilized for construction at a vast scale. Beaches which are completely eroded can be reinstated with the help of a slurry pump. Flood control systems also basetheir construction on this process in many locations around the world. Navigation Water ways can easily get clogged by the accumulation of earth and trash. It can result in a decrease of water traffic and unprecedented dangers with loss. A slurry pump can easily clean the bed of the waterways and make the area navigable. Hence it acts as an aid to trade and helps economies flourish. Environment Protection Even though dredging certainly has its own disadvantages, it has helped in the restoration of ecosystems around the world. Natural preserves have been cleaned and revamped with the help of a slurry pump and now there again exists a balance in the environment.
