在预应力混凝土斜拉桥挂篮悬浇施工中 ,利用斜拉桥的永久索作为悬浇挂篮临时牵索 ;将挂篮上的荷载传递给主塔 ,从而加大挂篮施工能力。武汉长江二桥主梁截面由双分离斜腹式单箱单室边箱梁组成 ,为安全移动挂篮 ,在梁面上设置三角架。用三角架的前吊杆吊挂挂篮的悬臂端 ,减小了 In the prestressed concrete cable-stayed bridge suspension cantilever construction, the use of cable-stayed bridge as the temporary suspension cable hanging rope temporary suspension; the load on the basket will be passed to the main tower, thereby increasing the capacity of hanging basket construction. Wuhan Yangtze River Bridge girder cross-section by the dual-separation slant belly single-box single-chamber box girder composition for the safe mobile hanging basket, setting the tripod on the beam surface. Use the front boom of the tripod to hang the cantilever end of the hanging basket and reduce it
