聚氨酯化学注浆与背水面防水处理技术

Polyurethane grout and negative side waterproof technique

除了常用的迎水面防水技术之外 ,背水面防水则更为困难、在某些条件下甚至无其他方法可代替。为增进人们的认识和推广应用新技术 ,介绍了三种背水面防水材料 ,及材料的形成发展过程、施工工艺、实用范围和在实践中存在的问题 ,特别是水泥基渗透结晶型防水材料 ,具有防水堵漏并能使混凝土致密的特殊效果。工程实例证明 。

Besides usually adopted positive side water proofing technique,the negative side water proofing is a more difficult and unsubstitutional engineering measure under certain conditions.For enhancing people's understanding,applying and disseminating new techniques,three types of negative side water proofing materials,their process of formation and development,construction technology,ranges of application and problems occurred in engineering practice,are introduced,especially the cementitious capillary/ crystalline waterproofing(CCCW) material which possesses special effectiveness of sealing leakage,anti seepage and keeping concrete compacting. Engineeing illustrations demonstrated that the coat of negative side waterproofing is advantageous to that of positive side water proofing.
