0.前言伴随着铁路跨越式发展,列车运行速度不断提高,对铁路要求越来越高,对既有铁路的更新改造越来越频繁,其中针对既有铁路平交改立交施工成为铁路改造的一项重点项目,在平改立工程施工过程中,对既有铁路进行线路加固,确保营运和施工两不误又成为平改立工程施工的重点。如何充分利用既有技术装备,最大程度降低施工成本,确保施工安全就成为平改立工程的关键,本文通过泰安望岳路立交桥施工方案的介绍及检算,就如何利用既有标准跨度的铁路D型施工便梁拼装,来完成大跨度的平改立工程施工进行简单介绍,供大家交流。
0. Preface Along with the leap-forward development of railways, the running speed of trains is continuously increasing, the requirements for railways are getting higher and higher, and the renewal of existing railways is becoming more and more frequent. In particular, As a key project, during the construction of Pingguangli Project, the line reinforcement of the existing railway line will ensure the correct operation and construction and become the focus of Pingguangli Project construction. How to make full use of the existing technology and equipment to minimize the construction cost and ensure the construction safety has become the key to reforming the project. Through the introduction and checking of the construction scheme of Wangyue Road overpass in Tai’an, how to make use of the existing standard span of railway D-type construction of beam assembly, to complete the long-span construction of the project to change a brief introduction for your exchange.
