简介:虽然钢筋混凝土的比重达2.5T/M3,其构件自重大,但当其形成薄壁水池构件时,在未灌水中空时,在特定环境下也会发生倾斜、漂移。1990年春节前,安徽省皖江机械厂两个400M3钢筋混凝土水池在施工过程中,由于拆模后未及时向池内灌水、池壁外回填土和池顶覆土,在外侧池塘渗透积水的浮力作用下,导致水池发生漂移,将池内立柱、底板与池壁连接处多处拉裂。一、两个400M3砼水池周围环境概况该蓄水池位于工厂生产区的东北隅,距东侧围墙约4米,围墙外侧有一面积约900M2深2米的水塘。工厂地下水位较低,约在自然地坪以下5M左右,两水池位于水泵房两侧,东西两厢布置,水池各为直径12.6M,高度3.5M的圆柱形钢筋混
