水塔贮水箱池底和项帽一般呈圆弧锥形,施工时整个塔箱贮水池需连续现浇钢筋混凝土。我单位在安县及绵阳市等数座大型水塔工程施工中,对贮水箱池底顶采取了以土泥代模的方法,取得了较好的效果。具体做法是:塔箱底按水平由定型组合钢模板支模。底平板钢模安装毕,再接续箱身圆弧形立支模到1.5米左右,然后放线,定准箱底弧形起拱高度,接着回填中等密实的粘性土或二、三类黄土。这种粘黄泥回填夯实到起拱高度的面层时,
The bottom of the water tower storage tank and the cap are generally arc-shaped. When the construction is completed, the entire tower tank needs continuous cast-in-place reinforced concrete. In the construction of several large-scale water towers in Anxian County and Mianyang City, the unit adopted the method of using clay instead of the bottom of the reservoir tank and achieved good results. The specific approach is: the bottom of the tower is leveled by the fixed combination steel template. The bottom plate steel mold is installed, and then the box body arc-shaped vertical mold is about 1.5 meters, and then the line is laid, the arch height of the bottom of the box is determined, and then the medium compacted clay soil or the second and third types of loess is backfilled. When this sticky yellow mud is backfilled to cover the height of the arched height,
