Pillar and abutment prefabrication construction method
An abutment prefabrication construction method belongs to the technical field of capital construction and comprises the steps of bearing platform construction, integral prefabrication of steel bars of a pier body and an abutment and bridge connection of pier steel bars and bearing platform steel bars. The reinforcing steel bars adopt special double coatings, the binding distance of the reinforcing steel bars is increased, and the pier body prefabricated reinforcing mesh is in the form of a hollow sleeve. The steel bars with the special coatings are reasonably designed and matched with the steel bars in diameter specification, the use amount of the steel bars is reduced, the structural complexity is reduced, the bearing capacity is not reduced, good corrosion resistance is achieved, the service life is longer, and the service life can reach 100 years. The prefabricated part of the pier body is designed into a hollow sleeve type, so that the bulkiness is reduced, and transportation, hoisting and assembling are facilitated; prefabricating of the pier body steel bars is added, the construction period for binding the pier body steel bars on site is greatly shortened, the influence of the environment is avoided, and the quality is better. The pier body and the pier abutment are integrally bound, the same steel bar can be used at the demarcation point of the pier body and the pier abutment, binding connection points of the demarcation point are reduced, the combining performance is enhanced, and the using performance of the pier abutment is improved.
一种墩台预制施工方法，所属基建技术领域，方法包括承台施工、墩身和墩台的钢筋的一体预制，桥墩钢筋与承台钢筋的架接；钢筋采用特制的双涂层，钢筋绑扎间距加大，墩身预制钢筋网为空心套筒形式。本发明利用特制涂层的钢筋与钢筋直径规格合理设计搭配，降低钢筋用量，降低结构复杂性，但不会降低承载力，并具有很好的防腐性，使用寿命更长，能够达到100年使用寿命。将墩身预制部分设计为空心套筒式，降低笨重性，方便运输、吊装组装；增加墩身钢筋的预制，大幅缩短现场绑扎墩身钢筋的施工工期，不受环境影响，质量更好。将墩身与墩台一体绑扎，墩身与墩台的分界点能够使用同一条钢筋，减少分界点的绑扎连接点，增强结合性，提高墩台使用性能。
