淮北桃园立井采用冻结法凿井,井壁结构采用由外层井壁、聚苯乙烯泡沫板、内层井壁和中央夹层组成的复合井壁结构形式。在取消了表土段的生根双锥形大壁座后,改用一段内外井壁整体浇筑混凝土代替生根壁座获得成功。这种内外壁整体浇筑代替壁座的方法,还相继在淮北任楼矿主、副井筒采用。现从理论上对该段井壁(代壁座段)进行初步分析计算。 The Taoyuan vertical shaft in Huaibei adopts the freezing method for shaft sinking. The shaft lining structure adopts the composite shaft wall structure composed of the outer shaft lining, the polystyrene foam board, the inner lining and the central lining. After the abolition of the root section of the root biconvex wall base, using a whole section of inner and outer wall cast concrete instead of rooting wall seat to be successful. This whole wall instead of wall pouring the whole method of pouring, but also in succession in Huaibei Lord mine, deputy shaft used. In theory, this section of the wall (on behalf of the wall seat segment) for a preliminary analysis and calculation.
