Transverse three-support-arm radial gate and method for controlling concentricity of support hinges of transverse three-support-arm radial gate
The invention provides a transverse three-support-arm radial gate and a method for controlling the concentricity of support hinges of the transverse three-support-arm radial gate. The method comprisesthe following steps that prestress is applied to a gate support hinge girder fixed on a mountain body through a prestressed anchor cable, and a large-span single-span support hinge girder is simply supported into three small-span continuous beams, and each section of the small-span continuous beam is provided with a trunnion; when the gate is opened for flood discharge, a prestressed anchorage can homogenize deformation of the trunnion girder under the action of underground water pressure and self weight of a mountain, so that relative displacement of the three trunnion positions meets the requirement of concentricity deviation of the gate trunnion. The deformation coordination of the three supporting arms of the radial gate can be controlled to the maximum extent, it is ensured that relative displacement of the three supporting hinges meets the concentricity deviation requirement, and the water retaining safety of the gate is improved.
本发明提供了一种横向三支臂弧形闸门及横向三支臂弧形闸门支铰同心度控制方法，对固定在山体的闸门支铰大梁通过预应力锚索施加预应力，将大跨度的单跨支铰大梁简支为三个小跨度连续梁，每一段小跨度连续梁被配置有一个支铰；闸门开启泄洪时，预应力锚固可均化受山体地下水压力和自重作用的支铰大梁的变形，使三个支铰位置的相对变位满足闸门支铰同心度偏差要求。本发明能最大程度控制弧形闸门三个支臂的变形协调性，确保三个支铰的相对变位满足同心度偏差要求，提高闸门挡水安全性。
