近几年来,随着国民经济的迅速发展,平交道口改立交的越来越多,其中,相当一部分采用了上跨形式。我局京广、陇海等主要干线已大部分实现了电气化,在修建上跨立交时如何减少架梁时对电气化的影响,减少对运输的干扰,是施工单位常常难以解决的问题,笔者在陇海线K871+051跨线公路桥施工设计中,用100型工字钢拚成简易架梁滑道,成功地完成了架梁任务。一、概况陇海线K870+936原有一处二班看守道口,两侧路堑高约9.8m,公路引道以7%的坡度下坡,瞭望条件差,交通不便,曾多次发生险情。洛阳铁路分局与地方政府多次报告要求取消平交道口,修建上跨立交桥。经路局立项批准,同意修建。
In recent years, with the rapid development of the national economy, more and more people pay more attention to the establishment of cross-border trade. Among them, a considerable part adopts the cross-border form. Most of the main lines of Jingguang and Longhai of our bureau have been electrified, and how to reduce the influence on the electrification of the girder during the overpass construction and reduce the interference with the transportation are often problems that the construction unit often can not solve. Longhai line K871 + 051 cross-line highway bridge construction design, with 100 I-beam into a simple girder slide, successfully completed the girder task. First, an overview Longhai line K870 +936 the original one of the second shift crossing, cutting about 9.8m high on both sides, the road leading to a gradient of 7% downhill, looking poor conditions, traffic inconvenience, there have been many dangerous situations. Luoyang Railway Branch and local governments repeatedly asked to cancel the level crossings and build overpass. Approved by the Road Authority project, agreed to build.
