Pouring construction process for bridge pier through concrete conduit method
The invention discloses a pouring construction process for a bridge pier through a concrete conduit method and relates to pouring construction processes for underground bridge piers through the concrete conduit method. The process mainly aims to solve the problems of low efficiency and the like as a result of two times of construction of a pile body and a pier currently. According to the process,firstly, cut-pile elevation of a bridge pile foundation is raised to the bottom of a bent cap or an abutment, and then a construction platform is filled, wherein the elevation of the construction platform is consistent with the new cut-pile elevation; after platform filling is completed, a steel casing is inserted and driven into a pile position, and next a construction pile foundation is poured according to the conduit method, wherein steel bars in pier height are arranged according to pier steel bars; the steel casing is pulled out after concrete is poured to the top face of the steel casing, and two theodolites are used for recording a plane position when the casing is pulled out; the pier casing is inserted again according to the recorded position, and concrete is supplemented again tothe bottom of the bent cap or the abutment; and after the concrete meets the strength requirement, a soil body within the height range of the pier is excavated, the pier casing is dismantled, and thepier concrete is maintained. The process has the advantages that the construction period is short, and construction cost is low.
一种桥梁墩柱混凝土导管法浇筑施工工艺涉及地面下桥梁墩柱混凝土导管法浇筑的施工工艺。主要是为解决目前桩身和墩柱分两次施工效率低等问题而发明的。先将桥梁桩基的截桩标高提升至盖梁或桥台的底部，然后填筑施工平台，施工平台的高程与新的截桩标高一致。平台填筑完毕后，在桩位处插打钢护筒，接下来按导管法浇筑施工桩基础，墩柱高度内钢筋按照墩柱钢筋设置。待混凝土浇筑至钢护筒顶面时拔出钢护筒，使用两台经纬仪记录护筒拔出时的平面位置。按照记录的位置再重新插入墩柱护筒，重新补充混凝土至盖梁或桥台的底部。待混凝土达到强度后，开挖墩柱高度范围内土体，拆解墩柱护筒，养护墩柱混凝土。优点是施工工期短，施工成本低。
