摘要
非预留伸缩缝具有施工便捷,质量可靠的特性。在欧洲,特别是以法国标准为主导的公路桥梁领域被广泛应用。依托塞内加尔机场高速公路项目,从伸缩缝选型三要素“伸缩量、交通量、密封性”出发,结合伸缩缝的使用舒适性、牢固耐用性、良好的密闭性和排水性及更换易行性对伸缩缝选型进行阐述,确保了推荐的经济适用产品获得了工程师的批准。总结形成了一套非预留伸缩缝施工工艺,少走弯路,使沟通更容易,工期更可控、成本更节省。
The non-reserved expansion joint is characterized by convenient construction and reliable quality.It is widely used in Europe,especially in the field of road and Bridge dominated by French standards.Based on the Senegal Airport Expressway Project,this paper elaborates the selection of expansion joint from the perspective of three elements of expansion joint type selection:expansion,traffic volume and sealing,combined with comfort,durability,good tightness,drainability and ease of replacement of expansion joint.At last,this paper summarizes and forms a set of construction technology of non-reserved expansion joint,which can make communication easier,construction period more controllable and cost-saving by taking less detours.
