Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor found that the overall erection length of the pedestrian bridge across the Wusong River in Lujia Town, Kunshan City exceeds 100 meters. The bottom of the river is not enough to prevent heavy objects from falling, and it is necessary to prohibit navigation, which will cause defects that affect normal navigation

Embodiment Construction

[0040] The following is attached Figure 1-3 The application is described in further detail.

[0041] The embodiment of the present application discloses a construction method of a prefabricated steel box girder pedestrian landscape bridge. refer to figure 1 , the construction method of the prefabricated steel box girder pedestrian landscape bridge comprises the following steps:

[0042] S1. First measure the position and range of the cofferdam on both sides of the river width direction, and then use the water dredger to dredge the silt within the cofferdam range, transport the silt to the designated place for stacking, and then carry out the driving of steel sheet piles.

[0043] When the steel sheet piles are driven, it is planned to start from both ends, and then gradually extend to close, try not to interrupt so as not to cause too much mud to affect the strength of the cofferdam. The driving of steel sheet piles needs to be carried out in sections and intensified, and ...

Abstract

The invention relates to a construction method of a prefabricated steel box girder pedestrian landscape bridge. The construction method comprises the following steps that S1, cofferdams are built in riverways on the two sides in the width direction of the riverways, and a plurality of pouring piles are poured; S2, a plurality of arch rib sections and box girder sections are prefabricated; S3, thearch rib sections are sequentially hoisted and installed on the pouring piles to form complete arch ribs, and then the box girder sections are installed on the pouring piles to form a steel box girder; S4, a plurality of auxiliary cables are tensioned between the steel box girder and the arch ribs; and S5, a bridge deck is laid on the top surface of the steel box girder. The construction method has the effects of improving the overall construction efficiency of a bridge and reducing the influence of construction on river navigation.

Description

technical field [0001] The present application relates to the field of bridge building construction, in particular to a construction method of a prefabricated steel box girder pedestrian landscape bridge. Background technique [0002] At present, in the construction process of the pedestrian bridge across the Wusong River in Lujia Town, Kunshan City, in order to ensure the normal navigation and flood discharge requirements in the river, the river cannot be cut off for drainage and then poured directly. [0003] In related technologies, in order to ensure the normal flood discharge requirements of the river channel, bridge piers are often erected at both ends of the river channel, and then poured and closed from both ends to the middle of the river channel by a bridge erecting machine, thereby completing the erection of the overall bridge. [0004] In view of the related technologies mentioned above, the inventor found that the overall erection length of the pedestrian bridge...
