PURPOSE: An anchorage unit and a support for a prestressed temporary structure are provided to reduce construction cost and period by working efficiently under the ground with decreasing the number of strut beams, and to support earth pressure and water pressure stably by adjusting tension of the support with forming various shapes and kinds of supports. CONSTITUTION: The support(11) is installed in a horizontal beam(50), and anchorage units(12) are installed at both sides of the horizontal beam. A steel wire(13) is strained by the anchorage unit, and strut beams(20) are installed at both sides of the horizontal beam to support the horizontal beam. The support and the anchorage unit are mounted to the horizontal beam with welding. The vertical support is placed in the position of an H-pile(10) to minimize moment to the horizontal beam, and the strut beam is integrated with the H-pile. A tendon is strained by using a height adjustable screw jack or a coupler in prestressing, and tension of the support is adjusted with the height adjustable support.
