Design method of large-span arch bridge pipe concrete pouring system, pouring system and pouring method
The invention relates to the technical field of large-span arch bridge pipe concrete pouring, in particular to a design method of a large-span arch bridge pipe concrete pouring system, a pouring system and a pouring method.According to the design method, the number of segments of a single main chord pipe is determined by combining the initial setting time of concrete and the time needed for full pouring of a half main chord pipe; the grading number of each section of main chord pipe is determined by combining the optimal working performance maintaining time of concrete and the time required for filling one section of main chord pipe, the concrete in the main chord pipe is in the optimal working performance during each-stage pouring, the pouring quality of each stage is improved, and improvement of the overall pouring quality is facilitated; meanwhile, the filling system scientifically determines the number of sections and the number of grades, so that the number of sections and the number of grades are combined with actual construction, and accuracy is achieved; the arrangement number and positions of the bin partition plates and the slurry inlet pipes can be accurately determined, accidents such as pipe blockage and pipe explosion caused by inaccurate segmentation and grading of a pouring system are effectively avoided, and the construction period, the construction safety and the pouring quality can be guaranteed.
本发明涉及大跨拱桥管内混凝土灌注技术领域，特别涉及大跨拱桥管砼灌注系统的设计方法、灌注系统及灌注方法，其设计方法结合混凝土的初凝时间和灌满半根主弦管所需时间确定单根主弦管的分段数量，结合混凝土最佳工作性能维持时间和灌满一段主弦管所需时间确定每段主弦管的分级数量，各级灌注时主弦管内混凝土均处于最佳工作性能，提高各级灌注质量，利于整体灌注质量的提高；同时，灌注系统科学确定分段数量和分级数量，使分段数量和分级数量与实际施工相结合，较为准确；利于准确确定隔仓板和进浆管的设置数量和位置，有效避免因灌注系统分段分级不准确导致的堵管、爆管等事故，有利于保证施工工期、施工安全和灌注质量。
