ON THE MECHANICS AND EFFECTIVENESS OF A WATERPROOFING PLASTIC SLEEVE IN CONCRETE SHAFT LININGS

文章介绍了两淮矿区在1978～1981年施工的十个塑料夹层井壁结构井筒的施工工艺、井壁结构特点和封水效果;探讨了塑料夹层井壁的封水机理;对AV井壁在我国的可行性进行了分析;对塑料夹层井壁的封水深度提出了看法;对塑料夹层井壁提出了改进意见。

synopsis This paper presents in detail the engineering techniques of sandwiching a plastic sleeve in between two reinforced concrete linings as applied in the construction of 10 completed shafts in the Liang Huai mining area in 1978-1981. It discusses the waterproofing mechanics of the plastic sandwich lin ing; the feasibility of employing the AV shaft lining under present conditions in China; the depth limitations of the plastic sandwich lining, and proposals for improving the waterproofing proper ties of the plastic sleeve.
