Fabricated pier bearing platform anchoring method
The invention belongs to the technical field of bridge construction, and particularly relates to a fabricated pier bearing platform anchoring method. Comprising the following construction steps that S1, surveying and setting out are conducted, and the size of a bearing platform and the position of an anchoring structure are determined; s2, a pile head is chiseled away, a pile foundation is detected, the pile top elevation is measured again, and a bearing platform foundation pit is excavated; s3, a cushion layer is arranged, and after accurate positioning, the anchoring structure is hoisted to the set position; s4, the steel bars penetrate through steel bar reserved holes in the anchoring structure, and the steel bars are welded; and S5, concrete is poured in a layered mode, and then backfilling maintenance is conducted on the foundation pit. According to the method, the bearing platform, the pile foundation, the bridge pier and the main beam can be better consolidated, and then the overall shear resistance and shock resistance of the bridge are enhanced.
本发明属于桥梁施工技术领域，尤其涉及一种装配式墩承台锚固方法。包括以下施工步骤：S1：测量放线，确定承台尺寸及锚固结构位置；S2：凿除桩头，桩基检测，复测桩顶高程，开挖承台基坑；S3：设置垫层，在准确定位后，吊放锚固结构至设定位置；S4：将钢筋穿过锚固结构上的钢筋预留孔，并焊接钢筋；S5：采用分层方式浇筑混凝土，后对基坑进行回填养护。该方法能够将承台与桩基、桥墩、主梁更好的固结，进而增强桥梁整体的抗剪、抗震能力。
