建筑工程防水层在某些位置上由于应力集中,变形频繁,雨水冲刷严重或外力损害,会较早地出现局部损坏,导致整个防水层未到合理使用年限即需返修。故在防水工程设计和施工中,对容易造成局部损坏的薄弱部位应设置增强层,以提高防水层的整体设防能力,延长整个防水层的使用寿命。 Construction of waterproof layer in some places due to stress concentration, frequent deformation, severe rain erosion or external damage, will appear earlier partial damage, leading to the entire waterproof layer is not to the reasonable use of the years that need to be repaired. Therefore, waterproofing engineering design and construction, vulnerable to local damage vulnerable parts should be set to enhance the layer in order to improve the waterproofing of the overall fortification capabilities to extend the life of the entire waterproof layer.
