Steel sand cylinder temporary support

The utility model discloses a steel sand cylinder temporary support, which is characterized in that the steel sand cylinder temporary support comprises a secondary cylinder at an upper part and a primary cylinder at a lower part, the secondary cylinder is inserted into the primary cylinder, concrete which is arranged on the same level of the upper end of the secondary cylinder is filled in the secondary cylinder and pure dry sand is filled in the primary cylinder. By adopting the structure, the temporary supporting of a bridge body during bridge construction and the removal of the temporary support after system transformation are facilitated. Since sulfur mortar is not used, the defects that the construction process is relatively complex, the construction operation is difficult, the construction period is long, pollution is usually caused to the environment and the concrete and dangers exist during construction when the traditional sulfur mortar temporary support is used can be avoided, and the smooth conduct
