20世纪八九十年代建造的大部分住宅,其屋面板为预应力空心板,目前渗漏现象普遍。本文结合一工程实例,分析了此类屋面的渗漏原因、渗漏治理的难点,提出了在不影响相邻屋面防水效果的要求下,通过“局部维修、开槽封堵、灌浆堵截”的施工工艺,解决了屋面渗漏的方案,实施效果好。
Most of the dwellings constructed in the 1980s and 1990s have roofing panels prestressed with hollow slabs, and the current leakage is widespread. Based on an engineering example, the causes of seepage of such roofs and the difficulties of seepage control are analyzed. It is put forward that through “local maintenance, slotting plugging, grouting plugging ”The construction process to solve the roof leakage of the program, the implementation of good effect.
