Embodiment Construction
[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0037] A kind of butt joint construction method of Bailey arch frame of the present invention, such as Figure 1 ~ Figure 3 shown, follow the steps below:
[0038] step 1
[0039] The worker assembles the single-row single-layer Bailey sheet 7 and the transverse connection support frame 8 at the shore abutment to form the assembled Bailey frame 1, and installs the arch closing and docking device 6 at the female end joint of the Bailey frame;
[0040] step 2 ...

The invention discloses a bailey arch butt joint and shut construction method, and the method comprises the steps of assembling a bailey rack with a single-row single-layer bailey sheet and a transversal connection bracing frame at an ashore abutment by a worker, and installing an arch shut butt joint apparatus at a bailey rack female connector; hoisting the bailey rack assembled in step 1 to an assigned construction place to butt joint a suspending arch in the air through two hoisting points of the bailey rack cable hoisting system; after assembling the arch, drawing vertically 2-4 channel segment buckle cables to an I-steel crossbeam at the bottom of the arch, and drawing transversally 2 channels for stabilizing a segment wind cable of the arch on the I-steel crossbeam to complete a whole segment of bailey rack. Repeat the steps above until the top of the arch so as to complete the whole arch erection. According to index like the construction place and the cable hoisting system for on-site bailey arch assembling, optimal hoisting and assembling combination suitable for the assembly is selected, and best hoisting and assembling combination is realized.
Description
technical field [0001] The invention belongs to the technical field of construction methods of Bailey arch frames of bridges, and relates to a butt joint construction method of Bailey arch frames. Background technique [0002] Due to the limitation of the prefabricated site or hoisting capacity of the arch box, when the traditional prefabricated hoisting cannot be realized, the construction method of cast-in-place concrete on the Bailey arch is very popular. When splicing straight standard Bailey pieces into a curved arch, Usually there are the following problems: [0003] 1. The number of hoisting is small, the number of hoisting is more, the docking is difficult, the assembly is slow, and then there are problems such as poor assembly quality and low overall stability of the arch. [0004] 2. Because the cable hoisting system has 10 tons, 20 tons, 30 tons and other models, and under certain site conditions, it is limited by the hoisting quality, and the assembly section of...
