秦山核电二期工程核岛区地下防水综合应用及施工技术

COMPREHENSIVE APPLICATION AND CONSTRUCTION TECHNOLOGY FOR UNDERGROUND WATERPROOFING OF QINSHAN PHASE ⅡNUCLEAR POWER STATION PROJECT

秦山核电二期核岛地下防水工程共设置３道防水系统，并采取特殊的构造防水与合理选择回填土的综合性方案。３道防水系统从外到内依次为：室外排渗系统（地下排水盲沟）、结构外侧材料防水（大面积特种氰凝涂膜防水层）和结构自身刚性防水（自防水混凝土）。采取上述措施后，取得了较好的效果。

During construction of Qinshan Phase ⅡNuclear Power Station project,there were 3-layer waterproofing underground systems implemented.It has adopted not only the special structural waterproofing but also the comprehensive technology of proper back filling method.These 3-layer waterproofing underground systems have been carried out successively as following:1,outside room drainage system(underground ditch drain) 2,structural external-side waterproofing materials (large area special low-polymerized ployurethane leakproofing agent film waterproof materials) and 3,structure's self rigid waterproofing system(self waterproofing concrete).The above mentioned measures have been proved fairly successful in waterproofing technology.
