Abstract
The utility model discloses a soil pressure balance beam vertical rod with multilayered axisymmetric curved plates at the end part. The soil pressure balance beam vertical rod with multilayered axisymmetric curved plates at the end part comprises a bottom supporting piece and a head wire supporting piece, the head wire supporting piece comprises at least two standing plates and at least one wire supporting plate; the standing plates are fixed at the top end of the bottom supporting piece; the wire supporting plates are fixed between the standing plates; the wire supporting plates and the standing plates surround multilayered accommodating cavities used for accommodating steel stranded wires; the wire supporting plates adopt axisymmetric curved plates. According to the utility model, multiple standing plates and the multiple wire supporting plates are fixed at the top end of the bottom wire supporting piece; the standing plates and the wire supporting plates surround the multilayered accommodating cavities; since the accommodating cavities adopt hierarchical design, the steel stranded wires are prevented from winding with one another; the loss of prestress force is small; each root of the steel stranded wires is totally independent from one another and is not interfered by one another, so that pre-stress tension of the steel stranded wires can be realized for many times; acting force on all the steel stranded wires is shared by the multiple wire supporting plates; since component force of the steel stranded wires in the direction of vertical rods shared by each wire supporting plate is relatively small, the use safety of the soil pressure balance beam vertical rod becomes higher.
