Construction method and traction device for suspended and cantilever concrete bridge deck slab
The invention relates to the field of bridge construction, in particular to a construction method and a traction device for a suspended and cantilever concrete bridge deck, specifically, a precast beam is arranged above a cover beam, the bridge deck is poured at the top end of the precast beam of the same bridge deck in three sections, and when the cantilever bridge deck is poured, the bridge deck which is firstly poured and formed serves as a support to pull a pouring formwork. By the adoption of the technical scheme, the first section of bridge deck slab is firstly poured and formed, the poured first section of bridge deck slab serves as a follow-up pouring operation platform and a supporting platform, when the second section of bridge deck slab and the third section of bridge deck slab are constructed, the first section of bridge deck slab serves as a support to pull a pouring formwork, and therefore a supporting frame does not need to be erected with the ground as the support, and construction is convenient. The construction of the suspended and cantilever concrete bridge deck is not limited by the terrain of a construction area and the height of the bridge, so that the construction difficulty is reduced, and the construction cost is also reduced.
本申请涉及桥梁施工领域，尤其涉及一种悬空、悬臂的混凝土桥面板施工方法和牵拉装置，具体为：于盖梁上方布设预制梁，于同幅桥面的预制梁顶端分三段浇筑桥面板，在浇筑悬挑桥面板时，以先浇筑成型的桥面板为支撑牵拉浇筑模板。通过采用上述技术方案，先浇筑成型第一段桥面板，将已经浇筑完工的第一段桥面板作为后续浇筑作业平台和支撑平台，施工第二段桥面板和第三段桥面板时，以第一段桥面板为支撑牵拉浇筑模板，从而不必以地面为支撑搭设支撑架，使得悬空、悬臂混凝土桥面板的施工不必受施工区域地形和桥梁高度的限制，不仅降低了施工难度，也减少了施工成本。
