Vertical storage tank height reduction bottom changing construction method
The invention discloses a vertical storage tank height reduction bottom changing construction method, and the method specifically comprises the following steps: step 1, preparing for construction; step 2, performing protective detaching of related accessories and connection parts; step 3, locating distribution positions of a cutting line and a derrick; step 4, changing an edge plate of a tank bottom plate; step 5, cutting a wall plate; step 6, descending a tank body; step 7, welding the tank body; step 8, performing detection, test and corrosion prevention; step 9, performing restoring mounting of the accessories; and step 10, performing an inner floating disc lifting test and executing overall acceptance inspection. The vertical storage tank height reduction bottom changing construction method provided by the invention takes a single edge plate as a cutting unit, separates a bottom zone plate and the edge plate, firstly, changes the edge plate according to local symmetry, then, standsthe derrick, consequently reduces work procedures of detaching the derrick and standing the derrick for the second time, is advanced in technology and rational in optimization, and belongs to an advanced level in the same industry.
一种立式储罐降高换底施工方法，具体步骤如下，步骤一；施工准备：步骤二：相关附件、连接部件保护性拆除：步骤三：定位切割线及抱杆分布位置；步骤四：罐底板边缘板更换；步骤五：壁板切割；步骤六：罐体降落；步骤七：罐体焊接；步骤八：检验、试验、防腐；步骤九：附件恢复安装；步骤十：内浮盘升降试验、整体验收。本发明提供一种立式储罐降高换底施工方法，以单个边缘板为切割单元，分离底带板与边缘板，先局部对称更换边缘板，再立抱杆，减少抱杆的拆除和二次立抱杆的工序，工艺先进，优化合理，在同行业中属领先水平。
