Description
Technical field
The present invention relates to highway and municipal bridge technology, more particularly, to a kind of crossing river channel or the base-supporting tie-rod of cross-line
Arch bridge, the invention further relates to the construction method of the bowstring arch bridge.
Background technology
Through tied arch bridge will encircle with two kinds of structural groupings of beam together with, common bearing load, give full play to beam receive it is curved,
The pressurized compound action of arch, thus lower bearing arch bridge is that one of bridge type is commonly used in cross a river or cross-line newly building bridge.
The construction method of existing through tied arch bridge mainly includes rack construction method, construction by swing and cantilever-construction
Three kinds of methods, the key problem of above-mentioned three kinds of construction methods is the construction problem for solving arch rib.Rack construction method is in river course
Erection bracket is constructed, and the advantage of the method is simple to operate, there is the operation platform for being available for operating in work progress；But,
The long construction period of the method, has a strong impact on the navigation in river course；According to limited bracket, support collides with passing ships, deposits
In potential safety hazard.Construction by swing is the construction party that a kind of utilization landform and support are carried out cast-in-place or prefabricated arch rib by design altitude
Method, in work progress vertically or level to around skewback bottom vertical pivot rotate, make arch rib close up arching.The construction method is not
Need to set up support, work high above the ground is converted into into land operation, not only ensure construction safety and construction quality, and be easy to control
Construct really, reduce construction to river course or the interference of intersecting roads, but the method needs large-scale tumbler, increases
Fund input, and the control of tumbler is relatively complicated.Cantilever-construction is to carry out horizontal transport work by cable crane,
Arch ring sections is vertically sling and installed, using cantilever truss segmentation installation is carried out, arch ring is closed up, finally carry out suspension rod
Install, tensioning and floorings are constructed；The method needs to arrange tower crane（That is cable hoisting device）, increase fund input.Above-mentioned three
Plant construction method all to there is long construction period, need to arrange temporary facility（Such as support, tumbler or cable device）, to existing
Field execution conditions have high demands, it is impossible to the shortcomings of making full use of existing bridge, high cost.
The content of the invention
Present invention aims to the defect that above-mentioned prior art is present, there is provided a kind of through tied arch bridge, this
Invention also provides the construction method of the bowstring arch bridge.The bowstring arch bridge constructing operation of the present invention is simple, and short construction period, engineering is whole
