Small-radius curve cast-in-place continuous box girder construction method
The invention discloses a construction method of a small-radius curve cast-in-place continuous box girder. The construction method comprises the following steps of foundation treatment, replacement and filling treatment of a river valley section in the middle of a girder body and foundation pit treatment on the periphery of a pier column. The construction method comprises the steps of construction of a support, construction and calculation of a support system, reinforcement and protection of the support, and finally installation of a formwork. Performing a pre-pressing test on the bracket; the cast-in-place beam is constructed, steel bars are bound, concrete is poured, and the concrete is cured after pouring; the formwork and the support are sequentially dismantled after concrete is poured, through the series of construction methods, compared with a prefabricated box girder, the pouring time is greatly shortened while the quality of the concrete cast-in-place beam is guaranteed, and the production speed of the small-radius cast-in-place beam is remarkably increased.
本发明公开了小半径曲线现浇连续箱梁施工工法，包括以下步骤地基处理，梁体中间位于河谷段的换填处理和墩柱四周的基坑处理；支架的搭设，支架体系的搭设和计算，支架的加固和防护，最后进行模板的安装；支架进行预压的测试；现浇梁的施工，对钢筋进行绑扎，混凝土进行浇筑，浇筑后对混凝土进行养护；对混凝土浇筑之后对模板和支架进行依次拆除，通过此种一系列的施工方法，该技术在模板和砼的浇筑与预制箱梁相比，在保证了混凝土现浇梁的质量的同时大大的缩短了浇筑的时间，显著加快了小半径现浇梁的生产速度。
