小跨径连续梁新型受压式临时固结施工技术

Construction Technology of New Compression Type Temporary Consolidation of Small-span Continuous Beam

随着国内外重载铁路大跨度桥梁的普及,连续梁的施工技术日趋成熟,新型施工技术显得尤为重要;本文按照连续梁的施工工艺,对临时固结方法进行创新方案研究;明确了新型受压式临时固结的施工方法,从理论和实践上证明此方法的合理性、可行性;同时,此技术对连续梁0#块短小、0#块现浇支架布置的重难点,也给予了很大的启发作用,极具研究推广意义。

Along with the popularization of the large span bridge of the heavy haul railway at home and abroad, the construction technology of the continuous beam is becoming more and more mature, and the new construction technology is particularly important;according to the continuous beam construction technology, the temporary consolidation method is studied; the construction method of the new compression type temporary consolidation is defined, and the rationality and feasibility of the method is proved theoretically and practically; at the same time, the technology gives a great inspiration to the continuous beam 0# short block cast-in-place support layout,and has great significance of research and extension.
