Fabricated bridge and construction method thereof
The invention provides a fabricated bridge and a construction method thereof, and belongs to the technical field of bridge engineering. The fabricated bridge comprises prefabricated pile foundations,cast-in-place slurry, a cast-in-place bearing platform, prefabricated piers, prefabricated main beams, a cast-in-place pavement layer and prefabricated guardrails. The technical effects are that: communicating holes communicated with grouting holes are formed in the wall thickness direction of the prefabricated pile foundations, during grouting operation, the communicating holes can be filled withgrouting materials, compaction and reinforcement are conducted on surrounding soil foundations, later settlement of a tubular pile structure under the action of dynamic loads can be effectively reduced, and the bearing capacity of the whole prefabricated pile foundations is improved. Besides, the prefabricated pile foundations, the prefabricated piers, the prefabricated main beams and the prefabricated guardrails adopt standardized design, industrialized production and prefabricated construction modes, so that the standardized design is easy to popularize, the industrialized manufacturing efficiency is improved, the automatic production quality is strictly controlled, the construction bridging speed is increased, the labor intensity is reduced, the comprehensive cost is reduced, and the green, energy-saving and environment-friendly effects are enhanced.
本发明提供了一种装配式桥梁及其施工方法，属于桥梁工程技术领域，装配式桥梁包括：预制桩基，现浇注浆体，现浇承台，预制桥墩，预制主梁，现浇铺装层，以及预制护栏。技术效果：在预制桩基的壁厚方向开设有与注浆孔连通的连通孔，在进行注浆操作时，能够使注浆材料填充于连通孔内，并对周边土基进行挤密加固，能够有效地降低管桩结构在动载作用下的后期沉降，提高整个预制桩基的承载力。此外，预制桩基、预制桥墩、预制主梁和预制护栏采用标准化设计、工厂化生产、装配化施工的方式，能够使标准化设计易于推广，提高工业化制造效率，严格控制自动化生产质量，加快施工成桥速度，降低劳动强度，降低综合成本，加强绿色节能环保。
