An Analysis On Waterproof And Impervious Treatment Of Subway Engineering In Changchun

With the continuous development of subway engineering,waterproof of subway engineering has become a concern difficulty.In the process of utilizing the underground resources to build a subway,the selection of waterproof materials,construction technology and waterproof measures on some certain structure are directly impacted on the subway waterproof effection.Therefore,in the subway construction process,it is extremely important to select the waterproof materials and waterproof measures properly.This thesis discusses the selection of waterproof materials and waterproof measures and reasearched waterproof program in China.By studying the major city’s waterproof programs,we can safely draw the conclusion that the position of construction should be considered while selecting the waterproof materials.Under the premise of durability,we should select materials that adapted to the local environment and convenient to consturct.Avoiding to over-handle waterproofing contact between different materiel we should minimize the types of materiels.Under the premise of regulatory requirements in waterproof structure we should reduce setting construction joints and deformation joints and process the corners specifically.The establishment of drainage system should also consider the impact on surrounding environment.Finally, in the practice study of a changchun subway,comparing the difference between the specific construction and designed waterproof program,obtain the advantages and disadvantages of the changchun subway.Ultimately,test and verify the possible operation of waterproof program in certain subway of changchun...
