Embodiment Construction
[0024] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that all the drawings of the present invention are in simplified form and use inaccurate scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.
[0025] The steel truss bridge integral roll-on launching device provided by the present invention, such as figure 1 As shown, it includes a pontoon 10 that is arranged on the river near the abutment and a flatbed truck 20 on the bank. The upper surface of the pontoon 10 is laid with a track beam 11, and one end of the steel truss bridge 30 is fixed with a support shoe 12. A hoist 13 is also fixed on the buoyancy tank 10 , the hoist 13 pulls the steel truss bridge 30 to slide along the length direction o...

The invention relates to a steel truss bridge integral roll-on launching device and a construction method thereof. The device includes a floating box arranged in the river and a flatbed truck on the bank. One end of the bridge is provided with a supporting shoe, and the buoy is also provided with a winch, which pulls the steel truss bridge to slide along the length direction of the track beam, and the other end of the steel truss bridge is fixed on the on the flatbed. In the present invention, the pontoon is used to replace the ro-ro ship in the prior art to support one end of the steel truss bridge in the river, and at the same time, it is used as the traction end; end; when the hoist on the pontoon pulls the steel truss bridge, the supporting shoes slide in the track girder to realize the roll-on launching of the steel truss bridge, which has low requirements on the clearance of the river and the depth of the river, and is especially suitable for launching bridges in urban inland rivers Reset works.
Description
technical field [0001] The invention relates to the technical field of bridge construction, in particular to an integral roll-on-roll-off launching device for a steel truss bridge and a construction method thereof. Background technique [0002] Roll-on-roll-off transportation refers to a waterway transportation method that uses "roll-on-roll-off ships" to ship together with vehicles and goods. This transportation method has high loading and unloading efficiency and is suitable for wharves without lifting equipment. For inland river steel truss bridges that are returned to the factory for overhaul, often due to the weight of the bridge body and the large span of the bridge body, the performance requirements for the lifting equipment on the bank are extremely high. Therefore, roll-on transportation and launching have become the best way to save lifting equipment costs Excellent choice. [0003] However, the traditional ro-ro transportation requires flatbed trucks to load the ...
