1屋面防水工程的重要性做好屋面防水工程维护,延长防水层耐用年限。屋面工程竣工交付使用后,要长期在恶劣的环境下工作,经常要受到阳光的辐射,冰雪冻融,温差变形,结构变形,人为破坏,积尘积水,防水材料老化,植物滋生,根茎扎破防水层等的影响。这些影响逐渐使屋面防水功能由量变到质变,最后造成屋面渗漏。由小漏到大漏,直到发生严重破坏。这时再去修理,修复的难度和费用都大大增加。如果能及时管理和维护,防患于未然,及时排除屋面工程有害的各种因素,控制微小、局部损坏的扩展,及时加以维护,就可以大大延长屋面防水层的耐用年限。
1 The importance of roofing waterproofing Good roof waterproofing maintenance, prolong the service life of waterproofing layer. After the roofing project is completed and delivered for use, it will work for a long time under harsh environment and often suffer from sunshine radiation, freezing and thawing, temperature deformation, structural deformation, man-made damage, dust accumulation, waterproof material aging, plant breeding, Broken waterproof layer and other effects. These effects gradually change the quality of the waterproofing of the roof from qualitative to quantitative, resulting in roof leakage. From small leak to big leak until serious damage occurs. At this time to go to repair, repair the difficulty and cost are greatly increased. If the timely management and maintenance, take preventive measures, the timely elimination of various harmful roofing factors, the control of small, partial damage expansion, timely maintenance, you can greatly extend the durability of the roof waterproofing layer.
