Short-cantilever ballasting single-hole variable-height beam and construction method
The invention relates to a short-cantilever ballasting single-hole variable-height beam and a construction method. The short-cantilever ballasting single-hole variable-height beam comprises a main beam mid-span heightening section and main beam short cantilever ballasting sections assembled on the two sides of the main beam mid-span heightening section, the main beam mid-span heightening section is gradually lowered from a fulcrum to the mid-span, and the main beam short cantilever ballasting sections are arranged on a pier support and connected with the main beam mid-span heightening section; the pre-stressed anchor rod is arranged at the tail part of the short cantilever ballasting section of the main beam and is anchored in a foundation; the construction is convenient and fast; a conventional suspension casting method can be adopted for construction, support erection can be avoided, interference of support construction and crossing roads and river valleys is reduced, and construction is convenient and fast.
本发明涉及一种短悬臂压重单孔变高度梁及施工方法；包括主梁跨中变高段、装配于主梁跨中变高段两侧的主梁短悬臂压重段，所述主梁跨中变高段从支点向跨中逐渐变低，主梁短悬臂压重段设置于桥墩支座上，与主梁跨中变高段相连；所述预应力锚杆设置于主梁短悬臂压重段尾部，锚固于地基中；本发明施工方便、快捷；本发明可采用常规的悬浇法施工，可避免支架搭设，减少支架施工与跨越公路、河谷的干扰，施工方便快捷。
