Abstract
The invention belongs to the field of bridge engineering, and particularly relates to a steel arch bridge river crossing installation technology. The steel arch bridge river crossing installation technology is mainly used for a steel arch bridge. According to the technology, pier steel structures of the steel arch bridge are prefabricated and produced in a workshop and transported to a construction site, meanwhile, bridge boards of the steel arch bridge are prefabricated and produced in the workshop and transported to the construction site, construction is conducted from the two sides of the river to the middle of the river till the two ends are assembled, and therefore construction of the steel arch bridge is finished. By the adoption of the technology, construction of auxiliary facilities in the construction process can be reduced, the construction amount is reduced, time and manpower are saved, cost is reduced, and the project schedule can be guaranteed as well.
Description
Technical field
The invention belongs to science of bridge building field, particularly apply and get over river mounting technique in steel bow spanning.
Background technology
Bridge crosses over river, mountain valley or other traffic line, the road is clear in realization, in recent years in order to make the traffic of two sides, river more convenient, economic development is rapider, and a large amount of crossing bridges, in construction, the invention provides steel bow spanning and get over river mounting technique, both can guarantee that the progress of engineering, time and manpower can be saved again, reduce cost, increase economic efficiency.
Summary of the invention
It is an object of the present invention to provide steel bow spanning and get over river mounting technique, be mainly used for steel bow bridge, engineering construction amount can be reduced by the present invention, save time and manpower, and can guarantee that project progress, and reduce cost, increase economic efficiency.
The technical solution used in the present invention is: producing steel bow bridge bridge pier steel construction in shop-fabricated, be transported to construction site, steel bow bridge bridge plate produces in shop-fabricated simultaneously, it is transported to job site, constructing in the middle of river two is lateral simultaneously, until joining in two ends, completing steel bow bridge construction.
Described steel bow bridge bridge plate, is made up of basic body steel construction.
Described construct in the middle of river two is lateral simultaneously, after i.e. steel bow bridge bridge plate is connected with bridge pier, lateral middle construct from two simultaneously, until two ends junction.
The present invention is applicable to steel bow bridge, by producing bridge pier steel construction and steel bow bridge bridge plate in shop-fabricated, after being transported to construction site, constructing in the middle of river two is lateral simultaneously, until joining in two ends, both can reduce the construction of auxiliary equipment in work progress, reduce construction volume, saving time and manpower, reduce cost, ensure that again project progress.
Accompanying drawing explanation
Fig. 1 is that steel bends bridge construction schematic diagram.
Fig. 2 is that steel bends bridge bridge plate structural representation.
Fig. 3 is basic body steel construction schematic diagram.
Reference: 1, steel bow bridge bridge；2, steel bow bridge bridge pier；3, seamless steel pipe；4, H profile steel；5, H profile steel diagonal brace.
Detailed description of the invention
Describe the present invention below with reference to accompanying drawing.But embodiments of the present invention are not limited to that.
Prefabrication steel bow bridge bridge pier 2 in workshop, prefabricated complete after be transported to construction site, and be fixed on the corresponding position, both sides, river of steel bow bridge design；Prefabrication steel bow bridge bridge plate as shown in Figure 2 in workshop, and it is transported to construction site, steel is bent that bridge bridge plate and steel bow bridge bridge pier 2 is fixing to be connected, the bow bridge bridge plate of basic body steel structure connection steel as shown in Figure 3 consisted of seamless steel pipe 3, H profile steel 4 and H profile steel diagonal brace 5, completes the extension of radial direction, constructs in the both sides in river simultaneously, until joining in steel Gong Qiao two ends, complete the construction of steel bow bridge bridge.
The present invention is not limited to above-mentioned embodiment, and anyone can obtain steel bow spanning under the enlightenment of the present invention and get over the installation method in river.All impartial changes done according to scope of the present invention patent and modification, all should belong to the covering scope of the present invention.
