摘要
渗漏成为当前轨道交通工程的主要病害之一,福建省城市轨道交通工程渗漏现象主要集中于混凝土裂缝、施工缝、变形缝及诱导缝部位。对福建省轨道交通工程渗漏进行治理时,首先分析渗漏原因,可知混凝土裂缝主要由于收缩及耐久性下降导致,而轨道交通工程中施工缝、变形缝及诱导缝产生渗漏的原因千差万别。在渗漏治理过程中,对治理原则、材料进行分析研究,并提出福建省轨道交通工程渗漏治理应遵循的原则及不同渗漏部位采取的具体治理措施。
Leakage has become one of the main diseases of rail transit engineering.The leakage phenomenon of urban rail transit engineering mainly concentrates on concrete cracks,construction joints,deformation joints and induced joints.It should be analyzed the causes of leakage firstly when treat the leakage of rail transit engineering in Fujian province,the main causes of concrete cracks are shrinkage and durability,and the reasons for the leakage of construction joints,deformation joints and induced joints in rail transit engineering vary widely.In the treatment of leakage,this paper analyzes and studies the principles and materials of treatment,and puts forward the principles that should be followed in the leakage treatment of rail transit engineering in Fujian province and the specific measures to be taken at different leakage locations.
