Construction method of prestressed concrete box girder bridge
The invention provides a construction method of a prestressed concrete box girder bridge. The construction method comprises the following steps that S1, a bridge foundation is constructed; s2, construction of a pier column is conducted; s3, a first 0 # block, a first cantilever section, a second cantilever section, a second 0 # block, a third cantilever section, a fourth cantilever section, a third 0 # block, a fifth cantilever section and a sixth cantilever section are constructed; s4, the cantilever sections at the two ends of the middle closure section are reversely jacked through jacking equipment; s5, construction of a middle closure section is conducted; s6, a first cast-in-place section of the side span cast-in-place section is constructed; s7, a tower is erected on the top of the first pier column and the top of the fifth pier column, and construction of a second cast-in-place section of the side span cast-in-place section is conducted; s8, construction of a side span closure section is conducted; and S9, construction of the remaining structure of the bridge is completed. According to the construction method of the prestressed concrete box girder bridge, the construction difficulty and the construction cost of the prestressed concrete box girder bridge are reduced.
本发明提供了一种预应力混凝土箱梁桥的施工方法，其包括如下步骤：步骤S1：进行桥梁基础的施工；步骤S2：进行墩柱的施工；步骤S3：进行第一0号块、第一悬臂段、第二悬臂段、第二0号块、第三悬臂段、第四悬臂段、第三0号块、第五悬臂段、第六悬臂段的施工；步骤S4：采用顶推设备将中部合拢段两端的悬臂段进行反顶；步骤S5：进行中部合拢段的施工；步骤S6：进行边跨现浇段的第一现浇段施工；步骤S7：在第一墩柱和第五墩柱的顶部搭设塔架，进行边跨现浇段的第二现浇段施工；步骤S8：进行边跨合拢段的施工；步骤S9：完成桥梁剩余结构施工。本发明一种预应力混凝土箱梁桥的施工方法降低了预应力混凝土箱梁桥的施工难度和施工成本。
