The amazing technology used in the construction of Palm Island in Dubai. In construction, technology can be used as a means to refine, accelerate construction times and achieve what seems impossible. Palm Islands was a complex project in the sense that only natural materials were used and the shape was quite particular. This land reclamation project expanded Dubai's coastline by 75 km, where 94 million cubic meters of sand and 5.5 million cubic meters of stone were used to create the palm-shaped island on which they would later luxury villas and hotels have been built, C.Gibling (2013, page 4). This required special technologies and techniques to ensure the success of the project.DredgesThe first challenge was to collect the sand and deposit it in certain areas of the sea. This was done using dredgers. Dredging according to the Oxford dictionary means clearing the bed (of a port, river or other water area) by collecting mud, weeds and waste. However, there are different types of dredgers, for the Palm Islands project, the drag suction hopper dredger (TSHD) was used because it is the only non-stationary dredger. This is because the dredge had to move from the suction area to the deposition area. The drag dredger with suction hopper is equipped with suction pipes dragged on the seabed during dredging, dredging pumps to suck the material, hopper where the dredged material is deposited and a swelling compensator to control the contact between the suction mouth and the seabed during dredging. Since Dubai is rich in sand as it is a desert, it was possible to use the right type of sand that was cohesive enough and was only found on the seabed. Rain Arch To create the shape of the palm tree, the rain arch was made. The dredging vessel is used for... middle of paper......sign and Construction challenges of the underwater directional crossings on the Palm Jumeirah, Dubai.
