浅谈箱涵沉降缝及防水层施工

Discussion on the Settlement Joint and Waterproof Layer Construction of Box Culvert

涵洞属于路基工程中满足交通、排洪、灌溉功能的结构设施,主要解决沿线两侧村庄或城市之间的交通以及田地的水利灌溉和泄洪,为惠民工程。有交通功能的涵洞对沉降缝及防水层的施工要求尤为严格,同时,优良的防水系统才能使结构物免遭水的侵蚀。论文通过成兰铁路工程实例,介绍了涵洞沉降缝及防水层施工的关键技术工序、施工过程中的质量控制要点,供类似工程参考。

Culvert is a kind of structural facility which can meet the function of traffic, flood discharge and irrigation in the subgrade engineering. It mainly solves the traffic between villages or cities on both sides of the road as well as irrigation and flood discharge in the fields. It is a beneficial project for the people. The construction of culvert with traffic function is especially strict to the settlement joint and waterproof layer. At the same time, excellent waterproof system can protect the structure from water erosion. Through the example of railway project from Chengdu to Lanzhou, this paper introduces the key technical procedures and quality control points in the construction of culvert settlement joints and waterproof layer, which can be used as reference for similar projects.
