Rapid construction method for overcrossing existing high-speed railway on large-span and large-section pedestrian overpass
The invention discloses a rapid construction method for overcrossing an existing high-speed railway on a large-span and large-section pedestrian overpass, and relates to the technical field of large-span overpass construction. The method comprises the following steps: measuring and taking points of existing facilities on a construction site by using a measuring instrument; importing the measured data into software, and carrying out modeling analysis on the construction site by using the software; and treating the foundation, building a lifting device walking channel and a lifting station point, and conducting concrete hardening treatment on the lifting station point. According to the construction method, installation of the overpass is completed through design of conventional materials such as steel plates and I-shaped steel and other auxiliary measures, the process principle is easy to understand, the construction method is simple, high operability is achieved, large hoisting equipment is adopted, a large-scale structure overcrossing the existing railway is hoisted, compared with a pushing method, a large number of temporary supports and pushing equipment do not need to be input, the requirement that the welding amount of an overpass structure is completed from hoisting to 60% within two hours can be met, construction procedures are reduced, and high economical efficiency, high construction efficiency and high safety are achieved.
本发明公开了一种大跨度、大截面人行天桥上跨既有高速铁路快速施工工法，涉及大跨度天桥施工技术领域。本发明包括如下步骤：利用测量仪器对施工现场既有设施进行测量取点；将测取的数据导入软件，利用软件对施工现场进行建模分析；对地基进行处理，修建起吊装置行走通道和起吊站位点，并对起吊站位点进行混凝土硬化处理。本施工方法使用钢板、工字钢等常规材料设计及其它辅助措施完成天桥的安装，工艺原理易懂，施工方法简单，具有较强的可操作性，采用大型吊装设备，对上跨既有铁路大型结构物吊装，相比顶推法无需投入大量临时支架及顶推设备，可以满足2个小时内完成上跨结构物的从吊装到焊接量完成60％的要求，减少施工工序，具有较高的经济性、较高的施工效率以及较高的安全性。
