Discussion of Issues on Waterproof Construction of Metro Station

Abstract

With the stable economic growth and rapid urban construction, urban metro is becoming the major transportation tool in medium and large scaled cities. Metro provides convenient and effective transportation services to the public. During the metro construction, water leakage issues occurred frequently and creates huge impacts on the construction and usage of metros. This paper analyzes the causes of metro station water leakage and states the detailed metro station foundation surface and waterproof layer construction techniques, waterproof techniques on construction joints and induction joints, concrete waterproof techniques and waterproof materials leaking stoppage techniques. It is critical to adopt scientific waterproof measures in construction which secure the metro construction quality. It has significant meanings to facilitate a sustainable development of metro construction corporates.
