Fabricated concrete U-shaped structure and construction method
The invention provides an assembly type concrete U-shaped structure and a construction method.The assembly type concrete U-shaped structure comprises a prefabricated bottom plate, a first prefabricated side wall and a second prefabricated side wall, the first prefabricated side wall and the second prefabricated side wall are symmetrically arranged on the two sides of the prefabricated bottom plate, and a first connecting steel bar is arranged at the position, opposite to the prefabricated bottom plate, of the first prefabricated side wall; second connecting steel bars are arranged at the positions, opposite to the prefabricated bottom plate, of the second prefabricated side wall, third connecting steel bars are arranged at the two ends of the prefabricated bottom plate, the third connecting steel bars, the first connecting steel bars and the second connecting steel bars are poured into single U-shaped structures through cast-in-place belts, and every two adjacent single U-shaped structures are poured into a whole through a transverse cast-in-place belt. The advantages of environment friendliness, small construction interference, high speed and the like of a prefabrication and assembly construction method are exerted, permanent and temporary combination is achieved, the sectional size of a traditional U-shaped roadbed structure is optimized, and the effects of reliable stress, good integrity, efficient assembly, construction period saving, land saving, earthwork reduction and environmental protection are achieved.
本发明提供一种装配式混凝土U型结构及施工方法，装配式混凝土U型结构包括预制底板、第一预制边墙和第二预制边墙，第一预制边墙和第二预制边墙对称设置在预制底板两侧，在第一预制边墙上与预制底板相对处设有第一连接钢筋，在第二预制边墙上与预制底板相对处设有第二连接钢筋，在预制底板两端设有第三连接钢筋，第三连接钢筋通过现浇带与第一连接钢筋、第二连接钢筋浇筑成为单块U型结构，相邻两个单块U型结构之间通过横向现浇带浇筑成为整体。通过发挥预制拼装工法绿色环保、施工干扰小、速度快等优点，永临结合，优化了传统路基U型结构的截面尺寸，达到受力可靠、整体性好、拼装高效、节省工期、节约用地、减少土方工程、利于环保的效果。
