Abstract: A tilt support structure is disclosed. The structure comprises a force exerted unit and a restriction unit, characterized in that the cross section of the end portion of the force exerted unit is larger than that of the middle section and the force exerted unit is mounted into the restriction unit, the restriction unit includes a single or a plurality of sleeves and in combination with concrete, cement slurry or enhanced steel beam or steel plate to form an external frame to restrict the main force exerted unit so as to prevent damage as a result of compression and the structure is stable under compression or pulling.
