The construction method of above-mentioned precast segment assembly concrete arch-type bridge, includes the following steps：
(1) arch seat construction is completed first, and the batch production for completing arch ring prefabricated subsection and soffit prefabricated subsection makes, in arch ring
Pre-buried steel hinge is respectively set and for permanently connected pre-embedded steel slab in the end of prefabricated subsection and soffit prefabricated subsection；
(2) each arch ring prefabricated subsection is hinged by pre-buried steel, using combined sling, in lifting lifting process, automatically
Forming curves shape arch ring, is positioned on skewback；
(3) by the way of pre-embedded steel slab welding, permanently connected each arch ring prefabricated subsection；
(4) soffit prefabricated subsection is symmetrically lifted, by the way of pre-embedded steel slab welding, permanently connected each prefabricated section of soffit
Section；
(5) prefabricated railing is installed, deck paving is completed.
Compared with prior art, the present invention has the advantages that：
(1) arch ring is dexterously divided into several " wedge-shaped prefabricated subsections ", is attached, is used by the way that hogback steel hinge is arranged
Combined sling, the automatic forming in lifting, soffit are also that precast segment is assembled, the present invention have it is very strong can application property, can
Realize that the fast industrialization of arch bridge is built.
(2) by " breaking the whole up into parts " the prefabricated integral hoisting with " collection zero is whole ", reduce the safety wind in work progress
Danger, prefabricated arch ring get a promotion than the quality of cast-in-place arch ring, enhance the safety of structure.
(3) over-the-counter prefabricated and on-site consolidation, need not set up template and holder at the scene, it is ensured that live civilized construction,
Site environment interference is reduced, the environmental protection concept of green construction is implemented.
