The invention relates to a construction method for dismantling an acid tank in a limited space, which comprises the following steps: neutralizing the acid concentration in the acid tank, and circularly washing with purified water; the groove body is cut into a plurality of sections according to the space size of the structural platform stand columns; an air pick is used for chiseling off the acid-proof bricks with the width of 300 mm in the cutting seam, and the groove body lining rubber is exposed; removing the cutting seam lining rubber by using a flat spade; disintegrating the tank body along the cutting seam by using oxygen acetylene; dismounting a structural platform checkered plate above the acid tank, hoisting the tank body by a travelling crane through the lower part of the platform, rotating by 90 degrees, and hoisting the tank body away from the side of the platform; rolling bar steel pipes are laid below, and the tank body is lifted out and placed in a designated position area to be stacked. The acid tank can be quickly disassembled, and the problem that the acid tank is not easy to disassemble in a limited space is solved. The acid tank dismantling time can be shortened, and the construction method is reliable in connection; the crane is used for segmental disassembly, hoisting and dismantling, heavy physical labor is relieved, and working efficiency is improved.

    本发明涉及一种受限空间内酸槽拆除施工方法,中和酸槽内酸浓度,使用净化水进行循环冲洗;根据结构平台立柱间距尺寸,将槽体分段切割若干段;使用风镐凿除切割缝内耐酸砖宽度300mm,露出槽体衬胶;使用扁铲拆除切割缝内衬胶;使用氧气乙炔沿着切割缝解体槽体;拆除酸槽上方结构平台花纹板,行车通过平台下方吊装槽体,旋转90度,将槽体吊离平台边;下方铺设滚杠钢管,将槽体吊出摆放指定位置区域堆放。本发明能够实现酸槽快速拆除,解决了受限空间酸槽不易拆除的问题。本发明能够缩短酸槽拆除时间,施工方法衔接可靠;使用行车分段解体吊装拆除,减轻繁重的体力劳动,提高工作效率。
