Concrete drum-shaped hollow pier
The invention relates to a concrete drum-shaped hollow pier, which belongs to the technical field of large-span bridge construction and consists of a concrete foundation pile, a bearing platform, a hollow pier body, an eyebrow beam and a ground line from bottom to top. Wherein the bearing platform is provided with a cooling water pipe; the hollow pier body is composed of a concrete bottom plate, a transverse partition plate, a top plate, a pier body plate, a vertical partition plate, a lower-layer drum-shaped hollow part, an upper-layer drum-shaped hollow part, a lower-layer hollow large-dip-angle chamfer, a lower-layer hollow equiangular chamfer, a lower-layer hollow horizontal chamfer, an upper-layer hollow equiangular chamfer, an upper-layer hollow horizontal chamfer, an upper-layer hollow large-dip-angle chamfer, a drainage hole, a vent hole, a transverse partition plate hole and a transition angle. And steel bars are arranged on the transition angle chamfers and the pier body chamfers. The construction method has the beneficial effects that stress is reasonable, theoretical stress is matched with designed stress, the structure is stable, the appearance is attractive, bending resistance and torsion resistance are good, the economical efficiency is improved, meanwhile, the masonry amount is reduced, the drainage capacity is high, the foundation engineering amount is reduced, the construction period is short, and the requirements for energy conservation and emission reduction are met.
本发明涉及一种混凝土类鼓状空心桥墩，属于大跨桥施工技术领域，其自下而上由混凝土式基桩、承台、空心墩身、眉梁和地面线组成。其中承台设冷却水管，空心墩身由混凝土底板、横隔板、顶板、墩身板、竖隔板、下层类鼓形空心、上层类鼓形空心、下层空心大倾角倒角、下层空心等角倒角、下层空心水平倒角、上层空心等角倒角、上层空心水平倒角、上层空心大倾角倒角、排水孔、通气孔、横隔板孔、过渡角、过渡角倒角和墩身倒角组成，并布设钢筋。本发明有益效果在于受力合理，达到理论受力与设计受力相匹配、结构稳定、外形美观、抗弯和抗扭性能好、提高经济性同时减少圬工用量、排水能力强、减少基础工程量、施工工期短、符合节能减排的需求。
