Assembly type prestress Y-shaped hollow pier
The invention discloses an assembly type prestress Y-shaped hollow pier, and belongs to the field of bridge engineering. The Y-shaped hollow pier is characterized in that a pile foundation and a bearing platform are foundations of the bridge, the pier arranged on bearing platform, the pier comprises an adjusting section, a plurality of standard sections and a pier cap section, the adjusting section, the standard section and the pier cap section are prefabricated reinforced concrete components and are all provided with ducts, steel strands penetrate through the ducts, the anchored steel strandsare arranged on the bearing platform, and the adjusting section, the standard section and the pier cap section are tensioned and anchored by applying prestress to the steel strands to form an integral assembled prestressed pier. The pier is prefabricated in a factory and assembled and combined on site, the procedures of binding steel bars, erecting a formwork, pouring concrete, maintaining, removing the formwork and the like of cast-in-place concrete are reduced, and the construction period of on-site construction is shortened; the reinforced concrete components are tensioned by applying prestress to the steel strands, so that the components are firmly fixed; the prefabricated components of the pier are of a hollow structure, the weight of the pier is reduced, and the foundation bearing capacity requirement is lowered.
本发明公开一种装配式预应力Y形空心桥墩，属于桥梁工程领域，桩基和承台为桥梁的基础，桥墩设置在承台上，桥墩包括一个调节段、若干个标准段和一个墩帽段，调节段、标准段、墩帽段为预制钢筋混凝土构件，调节段、标准段、墩帽段均设有孔道，内穿钢绞线，在承台设置锚固的钢绞线，调节段、标准段、墩帽段采用钢绞线施加预应力张拉并锚固，构成一个整体的装配式预应力桥墩。桥墩采用工厂预制，现场装配组合，减少了现浇混凝土绑扎钢筋、支模、浇筑混凝土、养护、拆模等工序，缩短了现场施工的工期；钢筋混凝土构件采用钢绞线施加预应力张拉，使构件之间牢固固定；桥墩的预制构件采用空心结构，减轻了桥墩的重量，降低了地基承载力要求。
