Waterproof Project On Metro
Mar 05, 2018

Metro is an important part of urban rapid rail transit. It has the advantages of large capacity, fast, punctuality, low energy consumption, less pollution and comfortable ride, enjoying the reputation of "green passage". At present, all countries in the world are making great efforts to develop the urban subway transportation system to solve the increasingly serious traffic pressure on the ground. Since the construction of the first phase of Metro Line 23.6km long in Beijing began in 1965 in Mainland China, the development of China's urban rail transit has reached 405km (including light rail) and the subway construction has entered a period of rapid development.


Waterproofing is an important part of the subway project. It is directly related to the subway operating environment, structural robustness and durability, urban environmental protection, subway operating costs and operational safety. Therefore, it is very important to make subway waterproofing very important and economical significance. However, it is not optimistic that as the subway projects are mostly below the groundwater level, seepage water phenomenon is more common. It reduces the operational efficiency of the MTRC and affects passenger comfort and even endangers traffic safety. How to carry out metro waterproofing and prevent the occurrence of common problems in the quality of seepage water has always plagued the engineering community and has become a challenging engineering project in the engineering field.
