近年来,交通的发展使得城市主干道行车速度接近准高速或高速状态,立交桥梁的应用也越来越多,桥梁、路面防水的重要性日益显现出来,许多桥梁因未重视防水使得钢筋混凝土遭到酸雨、渗透水的侵蚀而不得不加固改造,影响了桥梁的正常使用寿命,道桥的防水工程造价在整个桥梁工程中所占的比例很小,然而防水系统所发挥的作用却是巨大的。本文对改性沥青卷材防水系统施工工艺做了阐述。
In recent years, the development of traffic makes the driving speed of urban trunk road close to quasi-high-speed or high-speed state, and the application of overpass bridges is also more and more. The importance of waterproofing bridges and pavements has become increasingly apparent. Many bridges, due to lack of waterproofing, To acid rain, infiltration of water erosion and had to reinforce the reform, affecting the normal life of the bridge, waterproof bridge project cost a small proportion of the entire bridge project, but the role played by the waterproof system is huge . This article describes the modified asphalt membrane waterproofing system construction technology.
