Construction method for drilling existing roof and additionally building piping shaft
The invention relates to the field of building transformation, in particular to a construction method for drilling an existing roof and additionally building a piping shaft. The construction method comprises the steps that the surface of a roof is dug downwards to a structural layer to expose the structural layer, a temporary water retaining wall higher than the surface of the roof is built on the exposed structural layer, the temporary water retaining wall is detachable and is cylindrical to surround a to-be-perforated area of the structural layer; the structural layer is excavated in the to-be-perforated area to form a structural layer through hole in the to-be-perforated area, and the hole edge of the structural layer through hole is away from the temporary retention wall by a preset distance, so that an annular sinking table is formed in the portion, between the hole edge of the structural layer through hole and the temporary retention wall, of the structural layer in the to-be-perforated area; a permanent retention wall higher than the surface of the roof on the sinking platform is built, wherein the permanent retention wall is cylindrical to surround the structural layer through hole; and the temporary retention wall is dismantled. The temporary retention wall is arranged, so that the waterproof problem when a piping shaft is additionally built during roof tapping is solved.
本发明涉及建筑改造领域，尤其涉及一种既有屋面开孔加建管道井的施工方法。包括自屋面的表面向下挖至结构层以显露结构层，在所显露的结构层上修筑高于屋面的表面的临时性挡水墙，该临时性挡水墙是可拆除的，且临时性挡水墙呈筒状以包围结构层的待开孔区域；在待开孔区域内挖穿结构层以于待开孔区域内形成结构层通孔，且结构层通孔的孔缘离开临时性挡水墙预定的距离，以使待开孔区域内从结构层通孔的孔缘到临时性挡水墙之间的结构层形成呈环形的沉台；在沉台上修筑高于屋面的表面的永久性挡水墙，该永久性挡水墙呈筒状以包围结构层通孔；拆除临时性挡水墙。本发明通过设置临时性挡水墙，解决现有屋面开孔加建管道井时的防水问题。
