随着我国经济的快速发展,对铁路的投资日益加大,同时对铁路工程施工质量要求越来越高。涵洞是铁路施工中的重要组成部分,然而在施工过程中往往很难成为重点控制性工程,不能引起施工管理者的高度重视。所选用的作业队往往也没有专业施工经验,对施工中的一些细节很难按规范要求施工,虽然采取了一些措施,但依然出现沉降缝渗漏水造成基础持续沉降,结构物表面平整度差甚至出现蜂窝麻面,涵背过渡段回填没按规范要求填筑产生不均匀沉降等问题。对此很多施工人员对其采取人工修饰,修饰出来的东西不仅达不到美观效果也达不到质量效果。为此,笔者根据自己长期从事铁路工程施工的经验和教训,进行了认真分析总结,希望能对同行起到借鉴作用。
With the rapid economic development in our country, the investment in the railway is increasing day by day, meanwhile, the quality of the railway construction is getting higher and higher. Culverts are an important part of railway construction. However, it is often difficult to become a key controlled project during construction and can not attract the attention of construction managers. The selected team often do not have the professional construction experience, some of the details of the construction is difficult to press the construction requirements, although some measures taken, but there are still sinking seepage caused by continuous settlement of the foundation, the structure of the surface roughness is poor Even the emergence of honeycomb ma face, culvert transition backfill did not press the specifications required to fill uneven settlement and other issues. In this regard, many construction workers to adopt artificial modification, modified things not only fail to achieve the aesthetic effect but also fail to quality effect. To this end, the author has long been engaged in railway construction based on his experience and lessons learned, conducted a careful analysis and summary, hoping to play a reference for peers.
