Embodiment Construction
[0013] Below in conjunction with accompanying drawing, the present invention will be further described: as figure 1 As shown, the rapid steel bow bridge technology includes prefabricated pile foundation 1, prefabricated abutment 2, prefabricated steel frame 3, prefabricated bridge deck 4, prefabricated anti-collision barrier 5, steel strand pipe 6, and concrete 7. First, select a relatively wide horizontal ground, and after drilling holes on the ground, put 2 sets of prefabricated pile foundations 1 into the holes, pour concrete 7 into the pile body to form bored piles, and 1 set of prefabricated pile foundations consists of 4 Composed of steel pipes of the same size, 4 steel pipes are arranged in a square shape, and the distance between two groups of pile foundations is 50m. After fixing, weld the two prefabricated piers 2 on the pile foundation that has been filled with concrete 7, and pour two 0.5m high reinforced concrete piers to form the steel arch bridge foundation. Th...

The invention relates to a steel bow bridge quick manufacturing technology. Prefabricated pile foundations, prefabricated abutment walls, prefabricated steel frames, a prefabricated bridge panel, prefabricated crash barriers, steel strand pipes and concrete are included. Firstly, holes are formed in the ground through a drilling machine, two sets of prefabricated pile foundations are placed into the holes, concrete is poured to form drilling piles, one prefabricated pile foundation is composed of four identical steel pipes, the four steel pipes are arranged in a square shape, and the distancebetween the two sets of pile foundations is 50 m; after fixation, the two prefabricated abutment walls are welded to the pile foundations, and two 0.5 m tall reinforced concrete abutment walls are cast to form a steel bow bridge foundation; the two abutment walls are fixed to the ground in a welded mode through six steel strand pipes, the two sides of the steel bow bridge are provided with four rows of prefabricated steel frames to be fixed above the prefabricated abutment walls, the prefabricated bridge panel is formed by welding three steel plates, and the prefabricated crash barriers are formed by cutting and welding steel materials and evenly distributed on the two sides of the prefabricated bridge panel. The construction efficiency is greatly improved, and construction pollution is lowered.
Description
technical field [0001] The invention relates to the field of bridge construction, in particular to a rapid steel arch bridge technology, which is mainly used for fabricated steel bridges. Background technique [0002] With the rapid development of the transportation industry, the construction speed of bridges is gradually accelerating. However, traditional bridge construction takes a long time and has high construction costs, which do not match the rapid development of cities. The emergence of the steel bow bridge has solved the above problems very well, it can reduce the bridge construction cost, shorten the construction period, and prolong the service life of the bridge. The present invention proposes a rapid steel bow bridge technology, through which the skeleton of the entire bridge is assembled through a fully prefabricated assembly structure, and is properly matched with concrete pouring to form an assembly bridge with a stable overall structure. The technology is sim...
