Rapid construction method for steel trestle
The invention discloses a rapid construction method for a steel trestle, which relates to the technical field of bridge construction and comprises the following steps: constructing temporary steel pipe piles, erecting a temporary orifice platform, inserting and driving the temporary steel pipe piles, and erecting Bailey; lowering a steel casing and punching; steel pipe piles are installed and designed, and the steel pipe piles are inserted and driven in each steel casing; concrete is poured, and the steel casing is pulled out after the concrete is poured; steel pipe parallel connection construction; the upper structure construction sequentially comprises the steps of bearing beam installation, bailey beam installation, distribution beam installation and bridge floor installation, and before the upper structure construction, a temporary punching platform formed by laying channel steel is dismantled; bailey beam installation is operated after concrete in the designed steel pipe piles is finally set, construction cooperation is conducted through cooperation of the temporary steel pipe piles and the designed steel pipe piles, the temporary steel pipe piles form supports, the strength requirement of early-stage construction is met, part of steps are operated in the concrete curing process, the shutdown waiting time is shortened, and construction is more efficient and faster.
本申请公开了一种钢栈桥快速施工方法，涉及桥梁施工技术领域，其包括如下步骤：临时钢管桩施工及临时孔口平台搭设，插打临时钢管桩，架设贝雷；钢护筒下放及冲孔；安装设计钢管桩，每个钢护筒内插打设计钢管桩；浇筑混凝土，在混凝土浇筑后拔出钢护筒；钢管平联施工；上部结构施工，依次包括承重梁安装、贝雷梁安装，分配梁安装以及桥面安装，其中，在上部结构施工前，将槽钢铺设形成的临时冲孔平台拆除；待设计钢管桩内混凝土终凝后才操作贝雷梁安装，通过临时钢管桩配合设计钢管桩进行施工配合，临时钢管桩形成支撑，满足前期施工的强度要求，在混凝土固化过程中操作部分步骤，减少了停工等待时间的时长，使得施工更加高效快捷。
