浅谈公路桥预制梁先张法施工工艺

Shallow discussion on highway bridge prefabricated beam construction technology with pretension method

简要介绍了公路桥施工中预制梁先张法的施工特点,并重点阐述了先张法中的钢筋张拉施工、张拉台座的制作、混凝土的浇筑等技术,结合"铁路装车站公路桥"的实际情况,说明了各项技术的运用情况,以便先张法的推广应用。

This paper briefly introduces the construction features of prefabricated beam with pretension method in highway bridge construction,mainly introduces the steel reinforced tension construction,pretension formwork fabrication,and concrete pouring and other technologies with pretension method,and demonstrates the technology application condition by combining with actual condition of ＂railway loading station highway bridge＂,so as to promote the application the pretension method.
