The invention provides an emergency deployable cable-stayed bridge beam and a self-erecting construction method thereof. The cable-stayed bridge beam comprises a telescopic main beam structure, a maintower structure and a transportation platform. The transportation platform, the main beam structure and the main tower structure are connected to a platform pin shaft; the main beam structure is provided with a first driving locking device used for driving the main beam structure to be folded and unfolded. A plurality of stay cables are arranged between the main tower structure and the main beamstructure; one end of each stay cable is connected with the second driving locking device after being attached to a first guide wheel on the main tower structure in a winding manner, and the other endof each stay cable is hinged to the main beam structure at one point; a back cable is arranged between the main tower structure and the transportation platform; one end of the back cable is hinged tothe main tower structure, and the other end of the back cable is wound around a second guide wheel on the transportation platform and then connected with a third drive locking device. The back cableand the stay cable are located on the two sides of the main tower structure. The deployable cable-stayed bridge has the advantages of being large in spanning capacity, high in bearing capacity, adjustable in span, convenient and fast to self-erect and construct and high in maneuvering performance.
本发明提出了一种应急可展斜拉桥梁及其自架设施工方法，该斜拉桥梁包括可伸缩的主梁结构、主塔结构和运输平台；运输平台、主梁结构和主塔结构连接于一平台销轴；主梁结构上设置一用于驱动主梁结构收放的第一驱动锁定装置；主塔结构和主梁结构之间设有若干斜拉索；每根斜拉索的一端均绕附于主塔结构上的第一导向轮后与第二驱动锁定装置连接，另一端均与主梁结构铰接于一点；主塔结构和运输平台之间设有一背索；背索的一端与主塔结构铰接，另一端绕附于运输平台上的第二导向轮后与第三驱动锁定装置连接；背索和斜拉索位于主塔结构的两侧。本发明的可展斜拉桥具有跨越能力大、承载能力高、跨度可调、自架设施工便捷、机动性能高的优点。
