悬臂浇筑法因为具有大跨越能力、施工便捷、工期短、成本低等一系列优势，而

Cantilever Construction Method because the ability to have a big leap, construction convenient, short construction period, a series of low cost advantage, high pier of the bridge across the river, extensive application of large span continuous beam. Closure of mature technology is an important prerequisite to improve the basis for the stability of the bridge, the bridge across the river is the key technology project, it is necessary to strengthen quality control. Introduces the construction and its impact and effect on the structure of the bridge collapsed section cantilever beam, and the actual project as an example to explore the hanging beam construction points irrigation Closure segment.

Cantilever pouring method has a series of advantages such as large span ability, convenient construction, short duration and low cost, and is widely used in continuous beams of high-rise and large-span girders in cross-river bridges. Mature convergence technology is an important prerequisite to improve the stability of bridge foundation, but also the key technology of cross-river bridge project, and quality control must be strengthened. This paper introduces the construction of the suspended irrigation beam close section and its influence and effect on the bridge structure, and discusses the construction points of the suspended irrigation beam close section with the actual project as an example.

Cantilever casting method has a series of advantages, such as large span capacity, convenient construction, short construction period, low cost and so on. It is widely used in high pier and long-span continuous beam of river crossing bridge. Mature closure technology is an important prerequisite to improve the stability of bridge foundation, and also a key technology of river crossing bridge engineering. Therefore, quality control must be strengthened. This paper introduces the construction of the closure section of the cantilever beam and its influence and function on the bridge structure, and discusses the key points of the construction of the closure section of the cantilever beam taking the actual project as an example.
