Steel-concrete combined section of cable-stayed bridge and ultra-large area grouting construction method of steel-concrete combined section
The invention provides a cable-stayed bridge steel-concrete combined section and an ultra-large area grouting construction method thereof. The method comprises the steps of notch chiseling, partition wall arrangement, cushion block arrangement, first section steel tower installation and bearing plate grouting. Wherein the notch chiseling is realized by pouring the tower base to the top surface of a grouting layer in the construction process of the tower base, then reserving tower base concrete with the width of 30cm on the periphery of the top surface of the tower base, and chiseling over-poured concrete with the width of 5cm in a chiseling manner, region segmentation is performed by arranging a partition wall, and a cushion block is arranged to support the first section of steel tower; grouting is achieved by directly conducting grouting from the opening position of the pressure bearing plate. The concrete around the tower base is used as the fence, so that a template does not need to be erected, the pollution to the inclined plane of the tower base during grouting is avoided, and the grouting quality is improved; the partition wall adopts the grouting material and the rubber strip, so that the leakproofness is enhanced; by means of the construction method, guarantee is provided for high-quality and high-efficiency construction of super-large-area grouting of the steel-concrete combined section of the cable-stayed bridge.
本发明提供了一种斜拉桥钢混结合段及其超大面积灌浆施工方法，包括凿槽口、设置隔墙、设置垫块、安装首节段钢塔及承压板灌浆。其中凿槽口是通过在塔座施工过程中将塔座浇筑至灌浆层顶面，然后在塔座顶面除四周预留30cm宽的塔座混凝土外，用凿毛的方式将超浇的5cm混凝土凿除来实现的，通过设置隔墙进行区域分割，设置垫块以支撑首节段钢塔，灌浆是通过直接从承压板开孔位置灌浆来实现的。由于利用塔座四周混凝土用作围挡，不需要再支立模板，避免了灌浆时对塔座斜面的污染，提高了灌浆质量；由于隔墙采用灌浆材料和橡胶条，增强了密闭性；通过这种施工方法，为斜拉桥钢混结合段超大面积灌浆高质量、高效率的施工提供了保证。
