Caisson structures are widely used in jetty,wharf and levee construction because of their good stability and little underwater construction work. But caissons have to be constructed in special construction factories where there are transport instruments such as trolleys and trials. Building traditional transport instruments is expensive and needs a long construction time. Then in area far from caisson pre-construction factories it comes to be difficult to use caissons for construction. To build temporary construction factories near wanted construction area people need to find an easy caisson transport solution.
