Mountainous area ultrahigh main tower cable-stayed bridge installation method
The invention discloses a mountainous area ultrahigh main tower cable-stayed bridge installation method which comprises the steps that a wall-attached crane is arranged on a main tower, and an assembling pier top section and a bridge deck crane are sequentially hoisted by the wall-attached crane; after the wall-attached crane hoists the component on the bridge deck, the component is transferred bythe bridge deck girder transporting vehicle, and a transfer platform is additionally arranged at the sidewalk position of the bridge deck and used for the bridge deck girder transporting vehicle to receive a temporary parking point where the wall-attached crane is lifted to a bridge deck steel beam; bridge deck transferring: the bridge deck precast slabs and the sidewalk integral structure are transported to the front of a bridge deck crane through the lower part of the bridge deck crane, and the beams are taken and erected in front of the bridge deck crane; bridge segment components are hoisted and erected; and pouring a wet joint is poured and a corresponding stay cable is tensioned every time two sections of steel structure beams are erected, the wet joint is maintained to be equal instrength, and then the next round of hoisting erection is carried out until the whole bridge is completely installed and erected, so that the problems that the construction site is insufficient, the deck crane is complex to install, and construction equipment interferes with the stay cable under the special conditions of the stay cable can be solved.
本发明公开了一种山区超高主塔斜拉桥安装方法，包括在主塔上布置附壁吊机，由附臂吊机依次吊装组拼墩顶节段和桥面吊机；附壁吊机吊装构件上桥面后，由桥面运梁车对所述构件进行转运，并在桥面的人行道位置增设中转平台，用于桥面运梁车对接收附壁吊机提升至桥面钢梁的临时停靠点；桥面转运：桥面预制板和人行道整体结构通过桥面吊机下方运输至桥面吊机前方，由桥面吊机前方取梁架设；桥梁节段构件吊装架设；按每架设2段钢结构梁浇筑一次湿接缝和张拉相应斜拉索，湿接缝养生等强后进行下一轮次的吊装架设，直至全桥安装架设完毕，本发明能够解决施工场地不足、桥面吊机安装繁琐、斜拉索特殊条件下施工设备与斜拉索干涉的问题。
