Waterproofing Technologies and Measures of Prefabricated Concrete Buildings
According to a large number of engineering practices and literatures,the significance of the waterproof resistance of prefabricated concrete(PC)buildings was addressed in depth,and the waterproofing technologies and measures of PC buildings were systematically analyzed and innovatively classified.Accordingly,3 types of structural waterproofing measures and 5 kinds of constructional waterproofing measures of PC buildings were described in detail,and the waterproofing focus of PC buildings was further clarified.It is indicated that the waterproofing measures of PC buildings can be classified as structural,constructional and material waterproofing technologies,which are the fundamental,key and directional waterproofing measures,respectively.Therefore,such waterproofing measures as selecting the PC structure system with good integrity,applying proper constructional measures,producing PC parts with good quality,protecting the PC parts during storing and transporting,promoting the installation accuracy and quality of PC parts,enhancing the waterproof treatment of gaps and sealing methods,and intensifying the integration of waterproofing technologies and products should be considered comprehensively and applied integrally to improve the waterproofing resistance.
