Erecting method of cable-stayed bridge main beam and cable-stayed bridge main beam
The invention discloses an erecting method of a cable-stayed bridge main beam and the cable-stayed bridge main beam, and relates to the technical field of bridge construction. The method includes 1) prefabricating a plurality of steel beam assembly segments; 2) moving a bridge deck crane to the erected segmental beams; 3) sequentially hoisting the two steel beam assembly segments on cantilevers ofthe erected section beams by utilizing the bridge deck crane to form two connected section steel beams, after each section of steel beam is formed, connecting the section steel beams with a main tower of the cable-stayed bridge through stay cables, and tensioning the stay cables for the first time; 4) hoisting prefabricated concrete bridge deck slabs to the two section steel beams by using the bridge deck crane; 5) pouring a wet joint between the concrete bridge deck slabs, tensioning the stay cables on the two sections again, and when erection of the two section beams is completed, moving the bridge deck crane in the direction of the newly-erected section beams; and 6) repeating the steps 2-5 until all the segmental beams are erected. The erecting speed of the main beam of the cable-stayed bridge can be increased, and the beam erecting period is shortened.
本申请公开一种斜拉桥主梁的架设方法和斜拉桥主梁，涉及桥梁建设技术领域，架设方法包括：步骤1：预制多个节段钢梁组件；步骤2：移动桥面吊机于已架节段梁上；步骤3：使用桥面吊机在已架节段梁的悬臂上依次吊装两节段钢梁组件形成相连的两个节段钢梁，并在每形成一节段钢梁后，将节段钢梁通过斜拉索与斜拉桥主塔连接，以及初次张拉斜拉索；步骤4：使用桥面吊机吊装预制的混凝土桥面板于两个节段钢梁上；步骤5：浇筑混凝土桥面板间的湿接缝，并再次张拉两个节段上的斜拉索，当完成两个节段梁的架设时，向新架设的节段梁方向移动桥面吊机；步骤6：重复步骤2～5，直至全部节段梁架设完成。本申请能够加快斜拉桥主梁的架设速度，并缩短架梁周期。
