Embodiment Construction

[0081] The present invention will be further described below in conjunction with accompanying drawing.

[0082] see Figure 1 to Figure 10 , the construction method of the main bridge of a kind of down-through steel box arch bridge of the present invention, down-through steel box arch bridge comprises south bank approach bridge 200, north bank approach bridge 300 and main bridge 100. The main bridge 100 includes arch ribs 1, suspenders 3, main girders 4 and orthogonal special-shaped bridge decks 5; the arch ribs 1 have two upstream and downstream lines, and the middle is connected by 7 permanent cross braces 2, and the single arch rib 1 is divided into 37 The main beam 4 includes longitudinal beams and beams and is divided into 37 sections longitudinally along the bridge deck; the beams include two end beams 40 and several general beams, and the two end beams 40 are arranged separately At the arch foot on the north bank side and the arch foot on the south bank side, generally...

Abstract

The invention discloses a constructing method of a through steel box arch bridge. Construction is conducted in the sequence of arches first and then beams, and the method includes the main bridge starting section construction process, the support area main beam construction process, the support area arch rib construction process, the cantilever area arch rib construction process, the hanging rod construction process, the cantilever area main beam construction process, the bridge deck slab construction process and the system conversion construction process. Cable hanging construction is adoptedfor the cantilever area arch rib construction process and the cantilever area main beam construction process. By means of the construction method, the construction period can be effectively shortened, the work efficiency is improved, it is ensured that the bridge profile conforms to the design and standard requirements, risks can be reduced, and the potential safety hazards of upstream power station discharged flood and rainy flood season flood on temporary supporting piers and other structures at the center of a riverway are reduced to the maximum extent.

Description

technical field [0001] The invention relates to a construction method of a main bridge of an under-supported steel box arch bridge. Background technique [0002] The overall length of the under-supported steel box arch bridge related to the present invention is 402.5m, the span of the main bridge is 230m, the length of the main bridge is 233.2m, the deck width of the main bridge is 34.12m, the total length of the approach bridges on both banks is 169.3m, and the deck width of the approach bridge is 28.9m. rice. The main bridge type is simply supported arch bridge with steel structure. The upper part of the main bridge includes arch ribs, longitudinal beams, arch feet, beams, suspenders, cross braces, deck orthotropic plates, and arch rib decoration structures. The main bridge pier at the lower part of the main bridge adopts a portal frame structure pier, and the pier columns and pier top beams are all box-shaped hollow sections. [0003] Arch ribs: there are two left and r...
