1 概况在克拉玛依炼油厂第二套循环水第一期工程的钢筋混凝土水池施工中,我们首次采用分层赶浆连续浇筑的方法,从池底到池壁一次完成混凝土的全部浇筑。循环塔池底及池壁为双排双向钢筋,池深2.6m,池底厚300mm,壁厚250mm,较大塔池周长86.5m,较小塔池周长为68.8m,混凝土设计标号为3kN/cm~2(300~#),抗冻标号D250次循环,抗渗标号S80N/cm~2。 1983～1987年建设的16个大型水池,都
1 Overview In the construction of reinforced concrete tanks for the first phase of the second circulating water project in the Karamay Refinery, we first used the method of layered caking and continuous pouring to complete all the pouring of concrete from the bottom of the pool to the walls of the pool. The bottom of the circulatory tower and the wall of the pylon are double-row two-way steel bars with a depth of 2.6m, a thickness of 300mm at the bottom of the pool, a wall thickness of 250mm, a perimeter of a larger tower pool of 86.5m, a perimeter of a smaller tower pool of 68.8m, and a concrete design number of 3kN. /cm~2(300~#), antifreeze label D250 cycles, impermeability index S80N/cm~2. The 16 large-scale pools constructed from 1983 to 1987 were
