Step 3: setting up suspension bridge in the job location of pre-selection, track be laid on suspension bridge, according to number order successively by institute
One end that carrying trolley is placed in the track is stated, is fixedly connected with corresponding bridge section further according to number corresponding relationship
In on carrying trolley accordingly, the other end of the carrying trolley to the track is successively pulled in numerical order；
Step 4: when all carrying trolleies are placed on the track, by two sections of bridge section butt welding adjacent to each other
It is connected together, all bridge sections is made to be connected as one to form arch steel structure truss bridge, and by the arch steel structure truss-type bridges
The both ends of beam are fixed on ground；
Step 5: it releases and is fixedly connected with relationship between every section of bridge section and carrying trolley, will be welded using jack
Arch steel structure truss bridge jack up, removing all carrying trolleies and suspension bridge, construction terminates.
The curvature of the bottom surface of bridge section arch described in step 1 is consistent.
Carrying car frame's top surface area described in step 2 is less than bridge section arch corresponding with the carrying trolley number
The area of bottom surface.
Successively pulling the carrying trolley described in step 3 in numerical order is drawn by hoist engine or electric block
Driving.
Successively pulling the carrying trolley described in step 3 in numerical order is with constant at the uniform velocity towing.
The vehicle frame is made of fashioned iron steel-pipe welding, the fashioned iron steel that the top of frame is arranged along vertical direction by more
Pipe upper surface composition.
The idler wheel includes wheel shaft and hollow form wheel body, and wheel shaft both ends are fixed together with the vehicle frame, wheel body two
Rolling bearing is arranged at the port of end, rolling bearing inner ring is sleeved in the middle part of wheel shaft.
The track (4) is made of duplexing word steel.
The beneficial effects of the present invention are: technical solution of the present invention is used, each section of bridge section is made in advance, ensure that each
Each section of bridge section is towed to pre-position by carrying trolley and welded, make to weld by the outer dimension precision of section bridge section
The form accuracy of the arch steel structure truss bridge formed after connecing greatly improves, and alleviates labor intensity, meanwhile, carrying vehicle
Top of frame area corresponding with bridge section arch-shaped bottom face curvature is smaller on frame, manufacture easy to process, is conducive to improve vehicle frame
The accuracy of manufacture of top surface advantageously reduces the cost of manufacture of carrying trolley, compared with prior art, entire bridge erection of the invention
In the process without setting up moulding bed, the work such as is leveled, corrected without the assembly to each section of bridge section, enormously simplifying construction
Technique improves construction efficiency, in addition, during towing carrying trolley, related personnel can be far from carrying trolley and corresponding
Bridge section avoids personnel from being damaged, and ensure that the safety of construction personnel.

Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
As shown in Figures 1 to 4, a kind of arch steel structure truss bridge erection method of the invention, comprising the following steps:
Step 1: prefabricated multistage steel structural bridge beam section 1, every section of bridge section 1 all have arch bottom surface, to every section of bridge section 1
Serial number, the type arched steel structure truss bridge when all bridge sections 1 successively join end to end together according to number order；
Further, the curvature of 1 arch bottom surface of step 1 jackshaft beam section is consistent.
Step 2: according to every section of 1 numbering scheme of bridge section in step 1 for corresponding carrying trolley, trolley packet is carried
Vehicle frame 2 is included, 2 bottom of vehicle frame is equipped with idler wheel 3, and top of frame 21 is 1 arch-shaped bottom of bridge section corresponding with the carrying trolley number
The identical curved surface of face curvature；Further, carrying 21 area of car frame top surface is less than bridge corresponding with the carrying trolley number
The area of 1 arch bottom surface of beam section.Vehicle frame 2 is made of fashioned iron steel-pipe welding, and top of frame 21 is arranged along vertical direction by more
Fashioned iron steel pipe upper surface composition.Idler wheel 3 includes wheel shaft 31 and hollow form wheel body 32, and 31 both ends of wheel shaft are fixedly connected with vehicle frame 2
Together, rolling bearing 33 is arranged at 32 both ends port of wheel body, 33 inner ring of rolling bearing is sleeved on 31 middle part of wheel shaft.
Step 3: setting up suspension bridge in the job location of pre-selection, and track 4 is laid on suspension bridge, successively will according to number order
Carrying trolley is placed in one end of track 4, and corresponding bridge section 1 is fixedly connected on phase further according to number corresponding relationship
On the carrying trolley answered, the other end of carrying trolley to track 4 is successively pulled in numerical order；Further, track 4 is by double
I-steel is made.Further, successively towing carrying trolley is by hoist engine or electric block in numerical order in step 3
Traction drive.Successively towing carrying trolley is with constant at the uniform velocity towing in numerical order.
Step 4: when all carrying trolleies are placed on track 4, by two sections of bridge sections adjacent to each other, 1 butt welding
Together, all bridge sections 1 are made to be connected as one to form arch steel structure truss bridge, and by the arch steel structure truss bridge
Both ends be fixed on ground；
Step 5: it releases and is fixedly connected with relationship between every section of bridge section 1 and carrying trolley, will be welded using jack
Arch steel structure truss bridge jack up, removing all carrying trolleies and suspension bridge, construction terminates.
Using technical solution of the present invention, each section of bridge section is made in advance, ensure that the outer dimension essence of each section of bridge section
Each section of bridge section is towed to pre-position by carrying trolley and welded, make the arch steel structure formed after welding by degree
The form accuracy of truss bridge greatly improves, and alleviates labor intensity, meanwhile, on loading carriage with bridge section arch bottom surface
The corresponding top of frame area of curvature is smaller, manufacture easy to process, is conducive to the accuracy of manufacture for improving top of frame, is conducive to
The cost of manufacture of carrying trolley is reduced, compared with prior art, is not necessarily to set up moulding bed during entire bridge erection of the invention,
It the work such as leveled, corrected without the assembly to each section of bridge section, enormously simplifying construction technology, improve construction efficiency,
In addition, related personnel can avoid personnel from being touched far from carrying trolley and corresponding bridge section during towing carrying trolley
Wound, ensure that the safety of construction personnel.
