Support method construction method for main bridge steel beams and arch ribs for crossing riverway
The invention discloses a support method construction method for a main bridge steel beam and an arch rib for crossing a river channel, and belongs to the technical field of bridge construction.The support method construction method comprises the following steps that a main bridge steel beam temporary support is constructed firstly; constructing a plurality of groups of main arch steel pipe pile brackets; then main bridge steel beams are closed; secondly, auxiliary arch lattice supporting frames are symmetrically erected on the two sides of a bridge deck of a main bridge steel beam, the corresponding auxiliary arch sections are symmetrically installed on the auxiliary arch lattice supporting frames, inter-arch decoration sections are hoisted between the auxiliary arch sections, main arch lattice supporting frames are symmetrically hoisted on main arch steel pipe pile supports, and main arch sections are symmetrically hoisted on the main arch lattice supporting frames; and wind braces are hoisted between the corresponding main arch sections and the corresponding auxiliary arch sections. A support of a main bridge steel beam is constructed underwater, a main arch support is constructed in batches according to the underwater part and the overwater part, rock-socketed piles are arranged on the underwater part, and concrete is poured into the underwater part; and after the main bridge steel beam is completed, the overwater part of the main arch and the temporary support of the auxiliary arch are arranged in time according to the installation progress of the arch rib sections.
本发明公开一种用于跨越河道的主桥钢梁及拱肋的支架法施工方法，属于桥梁建筑技术领域，包括如下步骤：先施工主桥钢梁临时支架；然后施工多组主拱钢管桩支架；接着主桥钢梁合拢；接着在主桥钢梁的桥面板两侧对称架设副拱格构支撑架，并将对应的副拱节段对称安装在副拱格构支撑架上，并在副拱节段之间吊装拱间装饰节段，在主拱钢管桩支架上对称吊装主拱格构支撑架，并在主拱格构支撑架对称吊装主拱节段；在对应的主拱节段和副拱节段之间吊装风撑。本发明主桥钢梁的支架在水下施工，主拱支架按水下、水上两部分分次施工，水下部分设置嵌岩桩，灌注混凝土；主桥钢梁完成后，主拱水上部分和副拱的临时支架根据拱肋节段安装进度及时进行设置。
