Pier prefabricated spliced viaduct building method capable of shortening construction period
The invention relates to a pier prefabricated spliced viaduct building method. A plurality of piers are built, a bridge plate is built on the piers, and the specific process of building the piers comprises the steps that a subsection located at the bottommost position is poured on a construction site, and the first prefabricated subsection is connected to the subsection at the bottommost position in an overlapped mode to achieve height increase of the piers; and the second prefabricated subsection is connected to the first prefabricated subsection in an overlapped mode, then the height of the pier is increased, the height of the bridge pier is increased to meet the protection requirement in the same way, and the adjacent subsections are connected together through a plurality of inserting structures. The method has the advantage that the construction period can be shortened, and the problems that due to the fact that piers of an existing viaduct are of a cast-in-place structure, the construction period is long when the piers are high, and formwork supporting frames are inconvenient to build are solved.
本发明涉及一种桥墩预制拼接式高架桥建筑方法，建筑若干桥墩，在桥墩上建筑桥板，建筑桥墩的具体过程为，在施工现场浇筑位于最底下的分段，将第一个预制好的分段叠接到最底下的分段上实现桥墩的高度增加，再将第二个预制好的分段叠接到第一个预制好的分段上再实现桥墩的高度增加，依次类推而将桥墩的高度增加到防护要求，相邻的所述分段之间通过若干个插接结构连接在一起。本发明具有能够缩短施工周期的优点，解决了现有的高架桥的桥墩为现浇结构导致的桥墩高时施工周期长且搭建模板支撑架时不便的问题。
