摘要
针对朔黄铁路K549+014涵洞出现的混凝土腐蚀风化严重,沉降缝普遍渗水泛白,沉降缝处剥落露筋,边墙剥落露筋,中墙沉降缝周围混凝土鼓起、剥落等病害现象,提出了对应的套涵加固技术,论述了该方法的施工工艺、技术要求及适用性。实践证明,该方法应用于铁路涵洞加固,不影响运输,投资少,施工安全、快捷,可对类似的工程提供借鉴。
Aiming at the diseases of culvert at section K549 ＋014 on Shuozhou-Huanghuagang railway,such as concrete corrosion weathering seriously,settlement joint universal seepage whitening,settlement joint and side wall spalling and exposed reinforcement,the concrete of settlement joint in the middle wall cracking and spalling.The culvert reinforcement technology was proposed correspondingly,the method of construction technology and technical requirements and applicability was discussed in this paper.Practice has proved that the application of this method in the reinforcement of railway culvert will not affect the transportation,and the investment is less,the construction is safe and fast,and can provide a reference for similar project.
