Description
Technical Field
The utility model belongs to the field, and particularly relates to a steel box girder high-position girder falling buttress structure.
Background
For municipal bridge engineering of a busy road and a railway, in order to reduce the interference of bridge construction on traffic under the bridge, a pushing method is generally adopted for construction. For concrete beams, because of large weight and a large number of supporting points, the concrete beams are generally pushed by adopting a pulling method; for steel beams, the number of supporting points is small due to light weight, and walking pushing is generally adopted. In general, the construction sequence of the pushing method is as follows: after the construction of all the lower structures of the whole bridge is finished, pushing equipment is arranged on the bridge approach pier, and the construction of the upper structures of the bridge approach is carried out after the main bridge is pushed in place.
Under special conditions, for example, the steel structure main bridge cannot be erected in advance due to the influence of special reasons such as sites, transportation, epidemic situations and the like, and in order to ensure the overall construction period, the conventional construction sequence must be adjusted, namely, the bridge approach upper structure is constructed firstly, and then the main bridge pushing construction is carried out above the bridge approach. This results in the main bridge having to "drop" from above the approach bridge onto the permanent support.
Therefore, a pier capable of temporarily supporting a high-position drop beam is needed, and the pier is required to meet double guarantees of stability and safety.
