Temporary support construction method for bridge crossing riverway
The invention belongs to the technical field of bridge construction, and particularly relates to a temporary support construction method for a bridge crossing a river channel. The method comprises the steps that S1, after bridge stack wharfs on the two sides of a river channel are constructed, multiple sets of middle cross beam steel pipe pile supports are arranged in the center of a bridge in the direction of the bridge, and multiple sets of straining beam steel pipe pile supports are arranged on the two sides of the middle cross beam steel pipe pile supports; s2, multiple sets of main arch steel pipe pile supports are constructed on the outer sides of the two sets of straining beam steel pipe pile supports; s3, main bridge steel beams are constructed at the top ends of the middle cross beam steel pipe pile supports and the straining beam steel pipe pile supports; and S4, after construction of the main bridge steel beam is completed, auxiliary arch lattice supporting frames are symmetrically erected on the two sides of the bridge deck of the main bridge steel beam from the two sides to the middle of the river channel, and main arch lattice supporting frames are symmetrically hoisted on the main arch steel pipe pile supports. The temporary support is reliable in structure and convenient to mount and dismount, so that the construction period can be greatly shortened, and the construction efficiency is improved.
本发明属于桥梁施工技术领域，具体涉及一种跨越河道的桥梁的临时支架施工方法。S1.河道两侧的桥栈码头施工完成后，顺着桥的方向在桥的中心布置多组中横梁钢管桩支架，在中横梁钢管桩支架的两侧布置多组系梁钢管桩支架；S2.在两组系梁钢管桩支架的外侧施工多组主拱钢管桩支架；S3.在中横梁钢管桩支架和系梁钢管桩支架顶端施工主桥钢梁；S4.主桥钢梁施工完成后，从河道两侧向中间，在主桥钢梁的桥面板两侧对称架设副拱格构支撑架，在主拱钢管桩支架上对称吊装主拱格构支撑架。本发明的临时支架不仅结构可靠，而且便于安装和拆卸，因此能够极大的降低施工的工期，提高施工的效率。
