Pipeline structure for guaranteeing in-pipe concrete pouring compactness and bridge
The invention relates to the technical field of bridge engineering, and provides a pipeline structure and a bridge for guaranteeing the in-pipe concrete pouring compactness, and the pipeline structure for guaranteeing the in-pipe concrete pouring compactness comprises a main pipeline; one end of the main pipeline is provided with a pouring structure, the other end of the main pipeline is provided with a grout emitting structure, and concrete can enter the main pipeline from the pouring structure and flow out of the main pipeline from the grout emitting structure; the upper surface of the main pipeline is also provided with a gas emitting through hole; the gas emitting through holes are distributed in the length direction of the main pipeline at intervals and used for exhausting gas in the main pipeline. The problems that when concrete pouring is conducted on the steel pipe concrete combined member in the high-altitude low-air-pressure environment, the pouring compactness of concrete is difficult to guarantee, the pipe is prone to being blocked by the concrete, and the concrete is debonded and disengaged relative to a main pipeline can be solved.
本发明涉及桥梁工程技术领域，提供了一种用于保证管内混凝土灌注密实度的管道构造及桥梁，其中用于保证管内混凝土灌注密实度的管道构造包含主管道；所述主管道一端设置灌注结构，另一端设置冒浆结构，混凝土能够从所述灌注结构进入所述主管道内部并从所述冒浆结构流出所述主管道；所述主管道的上表面还设置有冒气通孔；所述冒气通孔沿主管道的长度方向间隔分布，所述冒气通孔用于排除主管道内部的气体。本发明能解决在高海拔低气压环境中对钢管混凝土组合构件进行混凝土浇筑时，难以保证混凝土的灌注密实度，容易发生混凝土堵管、混凝土相对主管道脱粘脱空的问题。
